<Embodiment>
An embodiment according to the present disclosure will be described. The controller for ophthalmologic apparatus (for example, controller 80) operates the ophthalmologic apparatus (for example, ophthalmic apparatus 1). An ophthalmic apparatus controller (hereinafter also referred to as a controller) is separated from the ophthalmic apparatus. The controller is communicably connected to the ophthalmic apparatus. The ophthalmologic apparatus is connected by, for example, wireless or wired. The controller mainly includes, for example, a first direction input unit (for example, the first input unit 81) and a second direction input unit (for example, the second input unit 82). The first direction input unit receives an input in the first direction. The second direction input unit accepts an input in a second direction different from the first direction. For example, the first direction input unit and the second direction input unit are arranged on different surfaces of the main body of the controller. For example, the first direction input unit is disposed on a first surface (for example, the surface F1), and the second direction input unit is disposed on a second surface (for example, the surface F2 or the surface F3) different from the first surface. . For example, the second surface is a surface that does not coincide with the first surface. For example, the second surface is a surface that forms an angle with the first surface, or a surface that does not contact the first surface. For example, one of the upper surface, the lower surface, the right side surface, the left side surface, the front surface, and the rear surface of the controller body is different from the other surfaces.

The operability of the controller is improved by arranging the first direction input unit and the second direction input unit on different surfaces. For example, the examiner can operate the first direction input unit with one finger (for example, thumb), and can operate the second direction input unit with another finger (for example, index finger, middle finger, ring finger, little finger, etc.). For this reason, when the examiner operates the first direction input unit and the second direction input unit alternately or simultaneously, it is not always necessary to remove the finger from the first direction input unit or the second direction input unit. Therefore, the examiner can operate the controller while stably holding it even when the controller is used with one hand. For example, even when the controller is operated with one hand, the examiner can easily input a three-dimensional direction. Further, when the controller is operated with one hand, dropping from the hand is suppressed. In addition, while operating the controller with one hand, the other hand can assist the subject (for example, opening the eyelid).

Note that the first direction accepted by the first direction input unit may be, for example, a direction in a two-dimensional plane. For example, the first direction may be a direction in the XY plane. The XY plane may be, for example, the direction of a plane perpendicular to the optical axis of the ophthalmologic apparatus. The second direction received by the second direction input unit may be, for example, a one-dimensional direction orthogonal to a two-dimensional plane (for example, an XY plane). For example, the second direction may be the Z direction. The Z direction may be, for example, the optical axis direction of the ophthalmologic apparatus. As a result, the examiner can easily input each direction in three dimensions.

Note that the first direction may be a direction in the ZX plane. The ZX plane may be a plane direction (horizontal direction) parallel to the optical axis of the ophthalmologic apparatus, for example. In this case, the second direction may be the Y-axis direction.

Note that the first direction input by the first direction input unit may be a one-dimensional direction. In this case, the controller may include a third direction input unit for inputting a third direction different from the first direction and the second direction. Thereby, the controller can input a three-dimensional alignment direction. The controller may be configured to issue a direction instruction in a two-dimensional plane with a finger other than the thumb.

The controller may include a function switching input unit (for example, a function button 83). For example, the function switching input unit accepts a function switching input for switching at least one of the functions of the first direction input unit and the second direction input unit. For example, the controller or the ophthalmologic apparatus may change the functions of the first direction input unit and the second direction input unit when receiving a signal from the function switching input unit. Thus, by providing a function switching input unit, a plurality of functions can be assigned to each input unit, and the number of input units can be reduced.

When the function switching input is received by the function switching input unit, the function of the first direction input unit or the second direction input unit may be switched by the controller, or the first direction input unit or the second direction by the ophthalmologic apparatus. The function of the direction input unit may be switched.

For example, the function switching input unit may accept an input for switching the input mode of the controller between the first input mode and the second input mode, for example. For example, the first input mode is an input mode in which an input in the XY direction is received by the first direction input unit and an input in the Z direction is received by the second direction input unit. For example, the second input mode is a mode in which an input in the ZX direction is received by the first direction input unit and an input in the Y direction is received by the second direction input unit. Thus, the setting can be switched in the input direction that is easy for the examiner to operate by the function switching input unit.

The function switching input unit may accept an input for switching an input from the first direction input unit or the second direction input unit to a signal for driving the jaw table, for example. Thereby, the examiner can easily adjust the height of the chin rest by the controller.

Note that the function switching input unit may accept an input for switching, for example, an input from the first direction input unit or the second direction input unit to a signal for switching the eye to be measured left and right. Thus, the examiner can easily switch the eye to be measured by the controller. Further, it is not always necessary to provide an input unit for switching between left and right eyes.

The function switching input unit may accept an input for switching the alignment mode. The alignment mode may be, for example, an auto alignment mode or a manual alignment mode. For example, the function switching input unit may accept an input for switching between the auto alignment mode and the manual alignment mode. Thus, the examiner can easily switch the alignment mode by the controller. For example, the alignment mode can be quickly switched by operating the controller when the alignment with respect to the eye to be examined cannot be performed in the auto alignment mode.

Note that the first direction input unit may be a direction input stick (for example, a stick 81a). The direction input stick receives a direction by being tilted, for example. For example, the direction input stick may have a structure in which the tilt angle is restored. The direction input stick may be pushable. For example, the control unit may detect an on / off operation signal when a direction input stick is pushed. For example, the ophthalmic device may begin measurement when the directional stick is pushed.

Note that the controller and the ophthalmologic apparatus may include a communication setting mode (for example, a pairing mode). For example, when the communication setting mode is executed in the ophthalmologic apparatus, the controller may notify the ophthalmologic apparatus that communication is possible. For example, the controller may notify the ophthalmologic apparatus that communication is possible when an input is received by a first direction input unit, a second direction input unit, a function button, or the like. This allows the ophthalmic device to easily find a controller to communicate with.

Note that the ophthalmologic apparatus or the controller may include a distance detection unit (for example, the communication unit 78 or the communication unit 84). The distance detection unit detects a relative distance between the ophthalmologic apparatus and the controller, for example. For example, when the distance is detected by the distance detection unit, the ophthalmologic apparatus or the controller may select the ophthalmologic apparatus or the controller that performs communication based on the distance. For example, an ophthalmic apparatus or controller may be paired with an ophthalmic apparatus or controller that has been approached to a certain distance, or may be paired with an ophthalmic apparatus or controller that is closest to the distance. In addition, the ophthalmologic apparatus or controller is paired with, for example, an ophthalmologic apparatus or controller that has approached a predetermined distance in a state where input is received by at least one of the first direction input section, the second direction input section, and the function switching input section. You may ring. For example, the distance detection unit detects the distance using a method using GPS, a method using RFID, a method using infrared ID, a method using a mobile phone or a PHS base station, and the signal strength of a wireless LAN. There are methods used. By using the distance information detected by the distance detection unit, it is possible to perform an operation by the controller only by approaching a desired ophthalmic apparatus without switching the pairing setting. In addition, in the controller for ophthalmologic apparatuses other than the present embodiment, a distance detection unit may be provided, and an ophthalmologic apparatus that communicates based on the distance to the ophthalmologic apparatus may be selected.

Note that the controller may include a storage unit (for example, storage unit 86) that stores alignment information. The alignment information is, for example, position information of the eye to be examined, or relative position information between the optometry part and the eye to be examined. And a controller may memorize | store the examiner's alignment information measured with a certain ophthalmologic apparatus, and may transmit the alignment information to another ophthalmologic apparatus. The ophthalmologic apparatus that has received the alignment information may obtain the movement position of the optometry unit based on the alignment information of a certain ophthalmologic apparatus, and move the optometry unit to the obtained movement position. Thereby, the ophthalmologic apparatus can perform alignment efficiently using the alignment information of another ophthalmologic apparatus. In addition, in the controller for ophthalmologic apparatuses other than this embodiment, the memory | storage part which memorize | stores alignment information may be provided, and the alignment information acquired from a certain ophthalmologic apparatus may be utilized for another ophthalmologic apparatus.

Furthermore, the ophthalmologic apparatus 1 of the present embodiment may include, for example, a face photographing unit 3, a housing 6, a display unit 7, an operation unit 8, a face support unit 9, and the like. For example, the face photographing unit 3 photographs the face of the eye to be examined, for example. For example, the face photographing unit 3 photographs a face including at least one of the left and right eyes. The housing 6 houses the optometry unit 2, the face photographing unit 3, the drive unit 4, and the like. The display unit 7 displays, for example, an observation image of the eye to be examined, a measurement result, and the like. For example, the display unit 7 may be provided integrally with the device 1 or may be provided separately from the device. The ophthalmologic apparatus 1 may include an operation unit 8. Various operation instructions by the examiner are input to the operation unit 8. For example, the operation unit 8 may be various human interfaces such as a touch panel, a joystick, a mouse, a keyboard, a trackball, and a button. The face support unit 9 supports, for example, the subject's face. The face support unit 9 may include a forehead pad 10 and a chin rest 11. The chin rest 11 may be moved in the vertical direction by driving the chin rest driving unit 12.

<Communication Department>
The ophthalmologic apparatus 1 may include a communication unit 78. For example, the communication unit 78 receives a signal from a controller described later. Further, the communication unit 78 may transmit a signal from the ophthalmologic apparatus 1 to the controller. Thus, the communication unit 78 performs transmission / reception with the controller. Note that the communication may be wireless or wired.

<Control system>
As illustrated in FIG. 2, the apparatus 1 includes an apparatus control unit 70. The device control unit 70 manages various controls of the device 1. The device control unit 70 includes, for example, a general CPU (Central Processing Unit) 71, a flash ROM 72, a RAM 73, and the like.

For example, the RAM temporarily stores various information. The apparatus control unit 70 includes an optometry unit 2, a face photographing unit 3, a drive unit 4, a display unit 7, an operation unit 8, a chin rest drive unit 12, a communication unit 78, a storage unit (for example, a non-volatile memory) 74, and the like. It is connected. The storage unit 74 is, for example, a non-transitory storage medium that can retain stored contents even when power supply is interrupted. For example, a hard disk drive, a removable USB flash memory, or the like can be used as the storage unit 74.

<Face shooting part>

For example, as shown in FIG. 3, the face photographing unit 3 of the present embodiment includes, for example, a photographing optical system 3A that photographs a subject's face. The imaging optical system 3A mainly includes, for example, an imaging element 3Aa and an imaging lens 3Ab. The face photographing unit 3 of this embodiment is moved together with the optometry unit 2 by the driving unit 4. Of course, the face imaging | photography part 3 may be the structure fixed with respect to the base 5, for example, and not moving.

<Optometry section>
The optometry unit 2 performs measurement, examination, imaging, etc. of the eye to be examined. The optometry unit 2 may include, for example, a measurement optical system that measures the refractive power of the eye to be examined. For example, as shown in FIG. 3, the optometry unit 2 includes a measurement optical system 20, a fixation target presenting optical system 40, an alignment index projection optical system 50, and an observation optical system (imaging optical system) 60. You may prepare.

The measuring optical system 20 has a projection optical system (light projecting optical system) 20a and a light receiving optical system 20b. The projection optical system 20a projects a light beam onto the fundus oculi Ef through the pupil of the eye to be examined. In addition, the light receiving optical system 20b takes out a reflected light beam (fundus reflected light) from the fundus oculi Ef via the periphery of the pupil in a ring shape, and captures a ring-shaped fundus reflection image mainly used for measuring refractive power.

The projection optical system 20a has a measurement light source 21, a relay lens 22, a hall mirror 23, and an objective lens 24 on the optical axis L1. The light source 21 projects a spot-like light source image from the relay lens 22 to the fundus oculi Ef through the objective lens 24 and the pupil center. The light source 21 is moved in the direction of the optical axis L1 by the moving mechanism 33. The hall mirror 23 is provided with an opening through which the light beam from the light source 21 through the relay lens 22 passes. The hall mirror 23 is disposed at a position optically conjugate with the pupil of the eye to be examined.

The light receiving optical system 20b shares the hall mirror 23 and the objective lens 24 with the projection optical system 20a. The light receiving optical system 20b includes a relay lens 26 and a total reflection mirror 27. Further, the light receiving optical system 20 b has a light receiving stop 28, a collimator lens 29, a ring lens 30, and an image sensor 32 on the optical axis L <b> 2 in the reflection direction of the Hall mirror 23. As the imaging element 32, a two-dimensional light receiving element such as an area CCD can be used. The light receiving aperture 28, the collimator lens 29, the ring lens 30, and the image sensor 32 are moved by the moving mechanism 33 in the direction of the optical axis L2 integrally with the measurement light source 21 of the projection optical system 20a. When the light source 21 is disposed at a position optically conjugate with the fundus oculi Ef by the moving mechanism 33, the light receiving aperture 28 and the image sensor 32 are also disposed at positions optically conjugate with the fundus oculi Ef.

The ring lens 30 is an optical element for shaping the fundus reflection light guided from the objective lens 24 through the collimator lens 29 into a ring shape. The ring lens 30 has a ring-shaped lens portion and a light shielding portion. Further, when the light receiving aperture 28 and the image sensor 32 are disposed at a position optically conjugate with the fundus oculi Ef, the ring lens 30 is disposed at a position optically conjugate with the pupil of the eye to be examined. The image sensor 32 receives ring-shaped fundus oculi reflection light (hereinafter referred to as a ring image) via the ring lens 30. The image sensor 32 outputs image information of the received ring image to the CPU 71. As a result, the CPU 71 performs display of the ring image on the display unit 7, calculation of refractive power based on the ring image, and the like.

Further, as shown in FIG. 3, in this embodiment, a dichroic mirror 39 is disposed between the objective lens 24 and the eye to be examined. The dichroic mirror 39 transmits light emitted from the light source 21 and fundus reflected light corresponding to the light from the light source 21. The dichroic mirror 39 guides a light beam from a fixation target presenting optical system 40 described later to the eye to be examined. Furthermore, the dichroic mirror 39 reflects the anterior segment reflected light of light from an alignment index projection optical system 50 described later, and guides the anterior segment reflected light to the observation optical system 60.

As shown in FIG. 3, an alignment index projection optical system 50 is disposed in front of the eye to be examined. The alignment index projection optical system 50 mainly projects an index image used for alignment (alignment) of the optical system with respect to the eye to be examined on the anterior eye segment. The alignment index projection optical system 50 includes a ring index projection optical system 51 and an index projection optical system 52. The ring index projection optical system 51 projects diffused light on the cornea of the subject's eye E and projects a ring index. The ring index projection optical system 51 is also used as anterior ocular segment illumination that illuminates the anterior segment of the subject's eye E in the ophthalmologic apparatus 1 of the present embodiment. The index projection optical system 52 projects parallel light onto the cornea of the eye to be examined and projects an infinity index.

The optotype presenting optical system 40 is provided on the optical axis L4 in the reflection direction of the light source 41, the fixation target 42, the relay lens 43, and the reflection mirror 46. The fixation target 42 is used to fix the eye to be examined when measuring objective refractive power. For example, the fixation target 42 is illuminated by the light source 41 and is presented to the eye to be examined.

The light source 41 and the fixation target 42 are integrally moved in the direction of the optical axis L4 by the drive mechanism 48. The presentation position (presentation distance) of the fixation target may be changed by moving the light source 41 and the fixation target 42. As a result, the refractive power can be measured by applying fog to the eye to be examined.

The anterior ocular photographing optical system 60 includes an imaging lens 61 and an imaging element 62 on the optical axis L3 in the reflection direction of the half mirror 63. The image sensor 62 is disposed at a position optically conjugate with the anterior segment of the eye to be examined. The image sensor 62 images the anterior segment illuminated by the ring index projection optical system 61. An output from the image sensor 62 is input to the CPU 71. As a result, the anterior eye image Ia of the eye to be examined imaged by the image sensor 62 is displayed on the display unit 7 (see FIG. 2). In the image sensor 62, an alignment index image (in this embodiment, a ring index and an infinity index) formed on the cornea of the eye to be examined is captured by the alignment index projection optical system 50. As a result, the CPU 71 can detect the alignment index image based on the imaging result of the imaging element 62. Further, the CPU 71 can determine the suitability of the alignment state based on the position where the alignment index image is detected.

<Controller>
The controller 80 receives an input by the examiner's operation and transmits an operation signal based on the input to the ophthalmologic apparatus 1. Thereby, the examiner can operate the ophthalmologic apparatus 1 by operating the controller 80. The controller 80 may include, for example, a first input unit 81, a second input unit 82, a function button 83, a communication unit 84, a control unit 87, a storage unit 86, and the like. For example, the first input unit 81 inputs a direction in the XY plane (for example, a vertical direction, a horizontal direction, a diagonal direction, or the like). The first input unit 81 is, for example, a stick-type input unit that can be tilted, and a tilt direction, a tilt amount, a tilt speed, and the like may be input thereto. The second input unit 82 inputs, for example, the front-rear direction on the Z axis. The second input unit 82 is, for example, a button for inputting on and off. The second input unit 82 of this embodiment includes, for example, a forward button 82a and a backward button 82b. As shown in FIG. 4, the first input unit 81 is disposed on the surface F <b> 1 of the controller 80, for example. The surface F1 is, for example, the upper surface of the controller 80. The second input unit 82 is disposed on the surface F2 of the controller 80, for example. The surface F2 is, for example, the front surface of the controller 80. For example, the first input unit 81 is provided at a position where the first input unit 81 is operated with a thumb while the grip 85 is held. For example, the second input unit 82 is provided at a position operated by the index finger or the middle finger in a state where the grip 85 is gripped.

As described above, the first input unit 81 and the second input unit 82 are arranged on different surfaces, so that the operability is improved. For example, the first input unit 81 is operated with the thumb and the second operation unit 82 is operated with the index finger and the middle finger, so that the examiner can be stabilized without releasing the finger from the first input unit 81 or the second input unit 82. A three-dimensional alignment operation can be performed in the holding state. Thereby, for example, the examiner can reduce the visual observation of the controller 80 or his / her finger, and can concentrate on the position confirmation between the examinee and the optometry unit 2. Further, the examiner is less likely to drop the controller 80 from the hand.

If the first input unit 81 and the second input unit 82 are arranged on the same surface (for example, the surface F1), the first input unit 81 and the second input unit 82 are operated with the thumb, and the XY direction In the operation and the operation in the Z direction, the finger must be moved between the first input unit 81 and the second input unit 82.

The first input unit 81 inputs, for example, a direction in the XY plane in the ophthalmologic apparatus 1. For example, the first input unit 81 according to the present embodiment accepts inputs in four directions (up, down, left, and right) or eight directions (up, down, left, and right) according to the tilting direction of the stick 81a. Of course, fine direction inputs of eight directions or more may be accepted. For example, the control unit 87 transmits a signal for moving the optometry unit 2 in the XY directions to the ophthalmologic apparatus 1 according to the input signal from the first input unit 81. The device control unit 70 moves the optometry unit 2 according to the signal from the first input unit 81. The first input unit 81 is disposed at a position where it can be easily operated with the examiner's thumb, for example. Since the thumb is separated from the other fingers and is considered to be easily moved in the vertical and horizontal directions, the first input unit 81 may be operated in a two-dimensional direction.

The second input unit 82 inputs, for example, the Z-axis direction. For example, the second input unit 82 includes a forward switch 82a and a backward switch 82b. For example, the control unit 87 transmits a signal for moving the optometry unit forward or backward in the Z-axis direction to the ophthalmologic apparatus 1 in accordance with an input signal from the second input unit 82. The device control unit 70 moves the optometry unit 2 according to the signal from the second input unit. For example, the apparatus control unit 70 advances the optometry unit 2 in a direction approaching the subject when the advance switch 82a is pressed, and retracts the optometry unit 2 in a direction away from the subject when the reverse switch 82a is pressed. Let

Of course, the second input unit 82 may not be the forward switch 82a and the backward switch 82b. For example, the second input unit 82 may include a lever, and the movement in the Z direction may be instructed according to the direction in which the lever is tilted. For example, the 2nd input part 82 may be provided with a roller, and the movement of a Z direction may be instructed according to the rotation direction of a roller.

Note that the first input unit 81 and the second input unit 82 may be arranged at symmetrical positions of the controller 80, respectively. For example, as shown in FIG. 5, when the controller 80 is viewed from above, it may be arranged at the position of the center line (symmetric axis) V1. In this case, it is easy to operate with either the left or right hand. The second input unit 82 may be disposed on the surface F3. The surface F3 is, for example, a lower surface.

The controller 80 may include a function button 83. The function button 83 receives an input for switching the function of each input unit, for example. The function button 83 may be provided on the same surface as the first input unit 81, for example. The function button 83 may be provided on the surface F1, for example. The function button 83 may be provided on the upper surface, for example. The function button 83 may be provided near the thumb, for example. For example, the function button 83 may be provided at a position that can be operated by the first joint in a state where the first input unit 81 is operated with the thumb of the thumb. For example, the function button 83 may be arranged at the position of the symmetry axis V1. Of course, the function button 83 may not be near the thumb. For example, the function button 83 may be in the vicinity of an index finger or a middle finger. When pressing the function button 83, both hands may be used.

For example, when the control unit 87 accepts a function switching input by pressing the function button 83, the control unit 87 converts the input from the first input unit 81 or the second input unit 82 into a left / right eye switching signal, a chin rest drive signal, and the like. May be.

As described above, by providing the function buttons 83, the number of buttons can be reduced, and by assigning a plurality of functions to the same button, it is possible to reduce the trouble of moving a finger to another button.

For example, the device control unit 70 may move the jaw table 11 in the vertical direction when the direction is input by the second input unit 82 while the function button 83 is being pressed. For example, in a state where the function switching input is received by the function button 83, the device control unit 70 moves the jaw table 11 upward when the forward button 32a of the second input unit 82 is pressed, and the backward button 82b is pressed. If this is done, the chin rest 11 may be moved downward. Thereby, the examiner can change the height of the chin rest 11 by the controller 80.

For example, the apparatus control unit 70 may switch the eye to be measured when the forward button 82a and the backward button 82b of the second input unit 82 are pressed simultaneously while the function button 83 is pressed. For example, after the measurement of the right eye of the subject is completed, when the function button, the forward button 82a, and the backward button 82b are pressed at the same time, the device control unit 70 drives the drive unit 4 to drive the left side of the subject. The optometry unit 2 is moved to a position where the eye is measured. Thus, the examiner can easily switch the eye to be measured by the controller 80.

<Control method>
Next, an example of a control operation for measuring the eye to be examined by operating the controller 80 will be described with reference to FIG. The controller 80 is assumed to be connected to the ophthalmologic apparatus 1 in advance.

(S1: Alignment (1))
First, the examiner adjusts the position of the measurement optical axis of the optometry unit 2 with respect to the eye E. For example, the examiner operates the first input unit 81 and the second input unit 82 of the controller 80 to adjust the relative positions of the eye to be examined and the optometry unit 2. For example, the apparatus control unit 70 moves the optometry unit 2 according to the signal received from the controller 80. For example, if the stick 81a is tilted by the examiner, the control unit 87 detects the tilt direction, tilt angle, and the like of the stick 81a and transmits them to the ophthalmologic apparatus 1. The device control unit 70 receives a signal from the controller 80, and moves the optometry unit 2 in the XY directions according to the tilt direction, tilt angle, and the like of the stick 81a. For example, when the advance button 82 a or the backward button 81 b is pressed by the examiner, the control unit 87 detects a signal from the forward button 82 a or the backward button 82 b and transmits the signal to the ophthalmologic apparatus 1. The device control unit 70 receives a signal from the controller 80 and moves the optometry unit 2 forward or backward in the Z direction. The device control unit 70 may control the moving speed of the optometry unit 2 according to the length of the input time of the first input unit 81 or the second input unit 82.

When the eye E is located outside the movable range of the optometry unit 2, the examiner may operate the controller 80 to adjust the height of the chin rest 11. For example, the examiner presses the forward button 82a or the backward button 82b while pressing the function button 83. When the control unit 87 detects signals from the function button 83 and the second input unit 82, the control unit 87 transmits a signal for adjusting the height of the chin rest 11 to the ophthalmic apparatus 1. For example, when the function button 83 and the advance button 82 a are pressed, the control unit 87 transmits a signal for moving the chin rest 11 upward to the ophthalmologic apparatus 1. Further, when the function button 83 and the backward button 82b are pressed, the control unit 87 transmits a signal for moving the chin rest 11 downward to the ophthalmologic apparatus 1. When receiving a signal from the controller, the device control unit 70 drives the chin rest driving unit 12 to adjust the height of the chin rest.

(S2: Measurement (1))
For example, the examiner performs alignment between the ophthalmologic apparatus 1 and the eye E while viewing the observation image Ia of the subject displayed on the display unit 7. When the alignment is completed, the examiner pushes in the stick 81a. When the control unit 87 detects that the stick 81 a is pushed, the control unit 87 transmits a measurement start signal to the ophthalmologic apparatus 1. Upon receiving the measurement start signal from the controller 80, the device control unit 70 starts measuring the eye E by the optometry unit 2.

(S3: Measurement eye switching)
When the examiner finishes measuring one eye, the examiner performs alignment with the other eye. In this case, the examiner may switch the eye to be measured to the left and right by operating the controller 80, for example. For example, when measuring the left eye after the right eye measurement, the examiner presses the forward button 82a and the backward button 82b simultaneously while pressing the function button 83. The control unit 87 detects input signals from the function button 83, the forward button 82a, and the backward button 82b, and transmits a signal for switching the measurement target eye from the right eye to the left eye to the ophthalmologic apparatus 1. For example, when receiving a signal from the controller 80, the device control unit 70 drives the drive unit 4 to move the optometry unit 2 from the measurement position of the right eye to the measurement position of the left eye. For example, the device control unit 70 moves the optometry unit 2 in the left direction. At this time, the device control unit 70 may move the optometry unit 2 toward the predicted position of the left eye based on information on the measurement position of the right eye, or the left acquired by the face photographing unit 3 The optometry unit 2 may be moved based on the eye position information.

(S4: Alignment (2))
When the switching of the eye to be measured is completed, the examiner operates the controller to align the optometry unit 2 with the other eye. For example, the examiner operates the stick while viewing the observation image Ia displayed on the display unit 7 to move the optometry unit 2 in the XY directions.

(S5: Measurement (2))
When the alignment is completed, the examiner pushes in the stick 81a of the controller 80 and performs an operation for starting measurement. The controller 87 transmits a measurement start signal to the ophthalmologic apparatus 1 when the stick 81a is pushed. When receiving the measurement start signal from the controller 80, the ophthalmologic apparatus 1 starts measuring the eye to be examined by the optometry unit 2. At this time, the apparatus control unit 70 may measure the eye to be examined at the position where the measurement start signal is received from the controller 80, or move the optometry unit 2 so that the position of the bright spot is within a predetermined range. Then, the measurement of the eye E may be started automatically. When the measurement is completed, the examiner may perform an operation for printing out the measurement result by operating the controller 80.

In the above description, alignment is performed manually by the controller 80, but manual alignment and automatic alignment may be used in combination. For example, the apparatus control unit 70 detects the eye to be examined from the face image obtained by the face photographing unit 3 and performs the rough alignment by automatically moving the optometry unit 2. When the anterior eye part of the eye E is detected in the observation optical system 60 by the optometry part 2 approaching the eye to be examined, the apparatus control unit 70 detects the alignment bright spot from the anterior eye part image of the eye E to be examined. May be detected, and fine alignment of the optometry unit 2 may be performed based on the position. The examiner may perform manual alignment by operating the controller 80 during execution of automatic alignment. For example, the apparatus control unit 70 may change the alignment mode from the automatic alignment mode to the manual alignment mode when receiving a signal from the controller 80 during execution of the automatic alignment. Thus, the examiner may interrupt the automatic alignment to perform manual alignment. When returning from the manual alignment mode to the automatic alignment mode, the examiner may switch the alignment mode by operating the controller 80, for example. For example, the examiner may perform an operation of tilting the stick 81a in a predetermined direction while pressing the function button 83. The apparatus control unit 70 may receive a signal from the controller 80 and switch the alignment mode.

When the controller 80 is a curved surface, the surface F1 on which the first input unit 81 is provided and the surface F2 on which the second input unit 82 is provided may be defined by the operating direction of each input unit. For example, as shown in FIG. 7, the tilt angle of the stick 81a may be defined by a plane perpendicular to the axis O1 where the tilt angle is 0 °, a plane perpendicular to the axis O2 in the button pressing direction, and the like.

In addition, as shown in FIG. 8, the controller 80 may be provided with an insertion portion 89 into which a finger can be inserted. For example, the controller 80 may be a pistol type, and may include a first input unit 81 on the upper surface and a second input unit 82 inside the insertion unit 89. Thus, by providing the insertion part 89 for inserting a finger, the controller is less likely to be dropped.

Note that the connection between the controller 80 and the ophthalmic apparatus 1 may be wired or wireless. In the case of wired connection, for example, the controller 80 and the ophthalmologic apparatus 1 are connected by being connected by a cable or the like. In the case of wireless connection, pairing setting between the controller 80 and the ophthalmologic apparatus 1 is performed. When performing pairing setting, for example, the examiner pushes the stick 81a of the first input unit 81 while pressing the function button 83 of the controller 80. The control unit 87 may execute the pairing mode when the function button 83 and the stick 81a are simultaneously pressed. In this case, the control unit 87 may notify the connectable ophthalmologic apparatus 1 that pairing is possible. The ophthalmologic apparatus 1 may perform pairing with the controller that has received the notification. As a result, the examiner can easily set the pairing.

In addition, the controller 80 and the ophthalmic apparatus 1 may switch pairing by RFID. For example, the communication unit 78 of the ophthalmologic apparatus 1 may include an IC reader, and the communication unit 84 of the controller 80 may include an IC tag. In this case, for example, the ophthalmologic apparatus 1 may read the IC tag of the controller 80 and set the pairing based on the information of the read IC tag. For example, the ophthalmologic apparatus 1 presses at least one of the input units (for example, the first input unit 81, the second input unit 82, the function button 83, etc.) on the portion where the IC reader is provided (for example, When it is brought close to several centimeters), it may be paired with the controller 80. Thereby, when the controller 80 is shared by a plurality of ophthalmologic apparatuses 1, the selection switching of the ophthalmologic apparatus 1 operated by the controller 80 is facilitated.

The device control unit 70 may switch the direction input by the first input unit 81 and the second input unit 82. For example, if the first input unit is tilted in a predetermined direction while the function button 83 is pressed, the device control unit 70 may switch the input direction between the first input unit 81 and the second input unit 82. Good. For example, the device control unit 70 may switch from the first input mode to the second input mode. For example, the device control unit 70 may switch the input direction of the first input unit 81 from the XY direction to the ZX direction and switch the input direction of the second input unit 82 from the Z direction to the Y direction. Accordingly, the examiner can select a favorite mode from the first input mode and the second input mode.

In addition, the ophthalmologic apparatus 1 may be equipped with the mounting part 13 for mounting | wearing with the controller 80, for example. For example, the mounting portion 13 may be provided on the housing 6, the base 5, or the like. By providing the mounting portion 13, it is possible to prevent the controller from being lost or dropped. For example, the mounting unit 13 may hold the controller 80 in a self-supporting state. As a result, the controller can be operated in a stable posture. The controller may be used not only by the examiner but also by the subject.
