Description

 Itoda ク リ ー Cleaner for optical information processing equipment and optical information processing equipment

 The present invention relates to a cleaner and an optical information processing apparatus for cleaning an optical head of an optical information processing apparatus.

 The “optical information processing device” in this specification means an information processing device capable of recording, Z, or reproducing data by using optical means. Therefore, in addition to a narrowly-defined optical information processing device dedicated to reading data from an optical disk, there is also a wide range of information processing devices including a type capable of rewriting data on an optical recording medium by a magneto-optical recording method or a phase change method. It is a concept. Background art

 In an optical disk device represented by a CD player or a DVD player, reading and writing of information from and to an optical disk are performed using an optical head. The optical head includes an objective lens that forms a laser spot on the recording surface of the optical disk by focusing laser light traveling from a laser light source. Dust may adhere to the objective lens, and if the objective lens becomes dirty, the read / write performance of the optical head deteriorates. Therefore, it is desirable that the optical head is periodically cleaned, and conventionally, various cleaners have been proposed as described below.

 Japanese Patent Application Laid-Open Publication No. 2000-2501296 describes a cleaner for an optical disk device. This cleaner has a brush provided on a disk. When the brush is brought into contact with the optical head of the optical disk device while the disk is rotated at a high speed by loading the cleaner into the optical disk device, the optical disk is cleaned.

Japanese Patent Application Laid-Open No. Hei 4-2-2214, Japanese Patent Application Laid-Open No. 5-120731, Japanese Patent Application Laid-Open No. 6_ In Japanese Patent Application Laid-Open Nos. 124444/73 and JP-A-8-55356 / 1994, cloth, wet chips, and elastically deformable contact members for cleaning an optical head are disclosed. A cleaner using a simple porous body or a sponge-like elastic member is described. In the cleaners described in these publications, as in the case of the cleaner described in Japanese Patent Application Laid-Open Publication No. 2000-251926, the above-mentioned contact member contacts the optical head while rotating at a high speed. By doing so, the optical head is cleaned. However, in these conventional techniques, since the contact member is brought into contact with the optical head while rotating at a high speed, the objective lens of the optical head may be damaged. Further, dust adhering to the optical head scatters into the optical information processing device due to a high-speed rotation of the contact member. Therefore, there is also a problem that dust remains and accumulates in the optical disc device. Disclosure of the invention

 Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

 1 and 2 show an example of a cleaner for an optical information processing device to which the present invention is applied. The cleaner is used for cleaning the magneto-optical disk drive, and includes a cartridge 4, a disk 1 contained in the cartridge 4, an adhesive sheet 2, a clamping disk 3, and a shutter 5. It is configured with.

The cartridge 4 is formed by joining the first member 40 and the second member 41 so as to form a space inside. The first member 40 has a window 40a. At the center of the cartridge 4, a clamping disk 3 rotated by a spindle 20 of the magneto-optical disk device Pi shown in FIG. 3 is mounted. In the center of the second member 41, a circular opening 41a is formed so as to expose one side of the clamping disk 3 so that the spindle of the magneto-optical disk device Pi can be contacted. Is formed. The shutter 5 is for opening and closing the window 40a, and normally keeps the window 40a closed by the force of a panel (not shown). On the other hand, when the cleaner Ci is loaded in the magneto-optical disc device Pi, the shutter 5 moves by the shutter opening mechanism of the magneto-optical disc device P #, and opens the window 40a. The adhesive sheet 2 is affixed to one side of the disc 1 at a position facing the window 40a. As the adhesive sheet 2, a material having a surface with sufficient adhesiveness to effectively adhere dust is used. However, a material having excessive adhesiveness is not suitable because the adhesive component adheres to the optical head 17 of the magneto-optical disk device Pi. The entirety of the adhesive sheet 2 has rubber-like elasticity, and a specific material thereof is silicone rubber. Materials that meet the above requirements and are widely distributed include, for example, KE 3495—Shin-Etsu Chemical Co., Ltd. SRT—33—S—Sakase Chemical Industry Co., Ltd. Specifically, the adhesive sheet 2 can be configured so that the entirety thereof is made of silicone rubber and is attached to the disk 1 with an adhesive or the like. Further, in the present invention, a configuration using a sheet in which only the surface layer portion is made of silicone rubber and an adhesive layer is formed on the other surface, and these are laminated with a base material may be adopted.

 The disk 1 has an opening 1a at the center, and the shape and size when combined with the clamping disk 3 are similar to a general cartridge type magneto-optical disk. The disc 1 is fixed to the second member 41 by fitting an opening 1a provided in the disc 1 with a pin 41b provided in the second member 41 of the cartridge. ing. On the other hand, the clamping disk 3 is rotatably supported by the first member 40 and the second member 41 of the cartridge 4. In the example shown in FIG. 1, the pin 40b provided in the first member 40 is inserted into the opening 3a provided in the clamping disk 3, and the clamping disk 3 is The clamping member 3 is rotatably supported inside the disk 1 by being sandwiched between the first member 40 and the second member 41. According to such a configuration, the cleaner uses the magneto-optical disk device P! When the disk 1 is loaded, only the clamping disk 3 is rotated by the spindle of the magneto-optical disk device Pi, and the disk 1 is not rotated.

Next, the configuration of a magneto-optical disk drive using the cleaner C will be described with reference to FIG. The magneto-optical disk device Pi includes an optical unit 13, a carriage 15, and a spindle 20. The optical cut 13 is composed of a laser light source, a light emitting system such as a prism for shaping light, a beam splitter for dispersing light returning from the optical disk, a detector for sensing the returned light, and a light collector for the detector. It has a light receiving system such as a lens that emits light (both not shown). The laser light 14 emitted from the optical unit 13 can be turned to the disk 1 by the rising mirror 16 of the carriage 15. The laser beam 14 passes through an objective lens 17a provided in the optical head 17 and is irradiated on a magneto-optical disk (not shown) loaded in the loading section 1 ^. (FIG. 3 shows a state in which the cleaner is loaded, and the magneto-optical disk is not shown.) The carriage 15 is provided with a bearing 19, and the disk 1 is provided with a bearing 19. It is movable in the radial direction. The optical head 17 is supported by a suspension (not shown) in the actuator 18. The position of the optical head 17 is controlled by the actuator 18 to perform focus control. Specifically, immediately after the magneto-optical disk device Pi is loaded with a magneto-optical disk or when data is read or written, the actuator 18 brings the optical head 17 closer to the magneto-optical disk, and the focusing is accurate. In this case, the actuator 18 is controlled to maintain the state. If the focusing is not properly performed, the above-described control is executed again, and the above-described control is repeatedly performed a fixed number of times until the focusing is properly performed. The optical head 17 includes a magnetic forming coil (not shown) in addition to the objective lens 1a. Next, the cleaning operation of the optical head 17 by the cleaner will be described.

First, when the cleaner Ci is loaded into the loading section Li of the magneto-optical disk device P, the clubbing disk 3 is held by the spindle 20. The window 40a is opened by moving the shutter 5 by the opening mechanism (not shown) of the magneto-optical disc device Pi. Next, focus control is started, and the objective lens 17 a is brought closer to the cleaner by the actuator 18. During this operation, the spindle 20 rotates, so that the cleaning disk 3 is rotated. Even in such a case, the disk 1 is not rotated by the above configuration. Therefore, the objective lens 17a is moved toward the stopped adhesive sheet 2, and the adhesive sheet 2 and the objective lens 17a come into contact with each other. At this time, the adhesive sheet 2 is stationary and does not physically wipe the lens 17a. However, since the adhesive sheet 2 has appropriate adhesiveness, dust from the lens 17a adheres to the adhesive sheet 2. As a result, the objective lens 17a is cleaned. On the other hand, since the adhesive sheet 2 is made of silicone rubber, it is difficult to reflect light. Therefore, since the detector cannot detect the return light, the focus control is continued thereafter. Therefore, by repeatedly driving the objective lens 17a up and down, the adhesive sheet 2 and the objective lens 17a come into contact repeatedly, and the cleaning of the objective lens 17a is repeated. After the above steps are repeated several times, for example, the magneto-optical disk device Pi recognizes that an error has occurred in disc determination, and ends the focus control. Thereby, the optical head 17 having the objective lens 17a is retracted to a predetermined position, and the cleaning of the objective lens 17a is completed.

 In this way, the adhesive sheet 2 does not rotate but remains stationary and only contacts the objective lens 17a. Therefore, there is almost no horizontal friction between them. In addition, the pressure-sensitive adhesive sheet 2 made of silicone rubber has flexibility, and at the time of contact, is elastically deformed so as to conform to the objective lens 1a, so that an unreasonable force due to collision or the like is not applied. Therefore, it is possible to prevent the objective lens 17a from being damaged and from damaging other portions of the optical head 17. Further, since the adhesive sheet 2 exhibits a function of retaining the dust attached to the surface thereof, the dust attached to the adhesive sheet 2 does not adhere to the reproduction objective lens 17a. Since dust is not wiped off at high speed as in the case of cleaning with a brush, dust is not scattered in the magneto-optical disk device Pi. Therefore, it is possible to prevent dust from remaining and accumulating in the magneto-optical disk device Pi.

4 and 5 show another example of the present invention. The cleaner C ₂ of the present embodiment includes: Unlike the cleaner C i, it is used for cleaning the optical disk device for reading and writing the medium without the cartridge. The cleaner disk 51, the clamping disk 52, and the ring-shaped adhesiveness The seat 53 is provided.

 The adhesive sheet 53 is attached so as to cover the entire circumference of one surface of the disk 51. As the material of the adhesive sheet 53, silicone rubber is suitable as in the above-described embodiment.

 The clamping disk 52 is fitted into an opening provided at the center of the disk 51. The annular concave portion 51a on the inner peripheral surface of the disk 51 and the annular convex portion 52a on the outer peripheral surface of the clamping disk 52 are fitted together, thereby forming the disk 51 and the clamping disk 5a. 2 are configured to be rotatable relative to each other in their circumferential direction and not to be displaced in their thickness direction.

Next, the operation of the cleaner C _2.

First, when loading the cleaner C ₂ to the loading of the optical disc apparatus, by the spindle 8 1 of the optical disc apparatus, Klang Bing disk 5 2 is held. Head 8 0 to the optical of the optical disk apparatus to perform focus control, to approach towards the lower side of the cleaner C ₂ to the cleaner C _2. After that, the objective lens 80a provided in the optical head 80 comes into contact with the adhesive sheet 53. At this time, there is a case where the clamping disk 52 is rotated by the rotation of the spindle 81. However, the disk 51 and the clamping disk 52 are configured to be rotatable relative to each other. Further, the disc 51 comes into contact with the objective lens through the adhesive sheet 53. Therefore, in the above case, at least while the adhesive sheet 53 and the objective lens 80a are in contact with each other, the disk 51 is stopped, and only the clamping disk 52 rotates. Then, the dust of the objective lens 80a adheres to the adhesive sheet 53, so that the objective lens 80a is cleaned. Therefore, the same tallening action as in the above-described embodiment can be obtained. FIG. 6 shows another example of a cleaner used in an optical disk apparatus for reading and writing a medium having no cartridge. Cleaner c ₃ of the present embodiment is similar to that configuration and cleaner c _2, a de Isku 6 1, a clan Bing disc 6 2, and a ring-shaped adhesive sheet 6 3. The clamping disk 62 is composed of a lower member 62a and an upper member 62b. A part of the lower member 62 a is inserted into the hole provided in the upper member 62 b through the hole provided in the disk 61, so that the upper member 62 a and the lower member 62 and b are combined. With such a configuration, the disk 61 and the crumbing disk 62 can rotate relative to each other, and do not come off in their thickness direction. According to this structure, the same effect as when cleaning with the cleaner C ₂ is obtained.

 FIG. 7 shows an example of a magneto-optical disk drive according to the present invention.

The magneto-optical disk device P ₂ includes an optical unit (not shown), a carriage 15, an optical head 17, and a spindle 20, similarly to the above-described magneto-optical disk device. Further, in addition to these, it has a cleaner 70. The cleaner 70 includes an arm 71, an adhesive sheet 72, and a driving mechanism 73.

 The adhesive sheet 72 is made of the silicone rubber used in the above-described embodiment, and is attached to the lower surface of the arm 71. The arm 71 can be rotated and moved up and down by a drive mechanism 73.

 The procedure for cleaning the optical head 17 by the cleaner 70 will be described below.

Can the optical disk D is loaded in the loading section L ₂ of the magneto-optical disk device P _2, the arms 71 are retracted to a position which does not interfere with the optical disk D. In FIG. 7, the cleaner mechanism 70 in the retracted position is shown by a solid line. And, the magneto-optical disc D is from summer and a state which is not loaded in the magneto-optical disc device P _2, the cleaning is initiated. First, the arm 71 is rotated by the drive mechanism 73 from the retracted position to a position immediately above the optical head 17. Next, the arm 71 is moved down in the direction of the optical head 17 by the drive mechanism 73. Then, the adhesive sheet 72 and the objective lens 17a of the optical head 17 come into contact with each other. And the objective lens 1 When the dust of 7a adheres to the adhesive sheet 2, the objective lens 17a is cleaned. Thereafter, the arm 71 is raised by the driving mechanism 73 in a direction away from the optical head 17 and then rotated to the retreat position.

According to such a configuration, the optical head 17 can be tarry-ung without the user performing an operation for loading the cleaner. Further, dust is attached to the adhesive sheet 7 2, because it does not scatter to the magneto-optical disk device P _2, can be avoided dust is deposited on the magneto-optical de Isku the device P _2. The adhesive sheet 72 and the objective lens 17a may be brought into contact by raising and lowering the optical head 17 without raising and lowering the arm 71.

 In the above embodiment, silicone rubber is used as the material of the adhesive sheet, but the present invention is not limited to this. In the present invention, the adhesive sheet can be made of a material having rubber-like elasticity other than silicone rubber.

 In the present invention, as the material of the adhesive sheet, for example, a gel-like substance containing silicone as a main raw material (for example, Alf Azier, trade name, manufactured by Diltech Co., Ltd.) may be used. This gel-like substance can have sufficient adhesiveness for adhering dust of the objective lens 17a, similarly to the silicone rubber used in the above embodiment. Moreover, the gel-like substance is soft and can be deformed by an external force. Therefore, even when this gel-like substance is brought into contact with the objective lens 17a, it can be flexibly adapted to the objective lens 17a. Therefore, when a gel-like substance is used, it is not particularly necessary to have elasticity.
