[Outline of the embodiment of the invention]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sewing apparatus according to the present invention will now be described with reference to the accompanying drawings, in which: Fig. 1 is a front view of a sewing machine 10 as a sewing apparatus, Fig. 2 is a left side view, and Fig. 3 is a functional block diagram showing a control system.

The sewing machine 10 is equipped with a needle up-down movement mechanism that uses the sewing machine motor 11 as a drive source to give up-down movement to the needle bar that holds the sewing needle 2, a bottom feed mechanism that uses the power of the sewing machine motor 11 to feed the workpiece from below the needle plate using a feed dog, an upper feed mechanism that uses the power of the sewing machine motor 11 to feed the workpiece using an upper feed 4 that contacts the workpiece from above, a shuttle mechanism, a fabric presser 3 that presses down the workpiece on the needle plate from above, a needle swing mechanism that arbitrarily moves the needle bar in a direction perpendicular to the fabric feed direction, a thread tensioner that applies thread tension to the upper thread that passes through the sewing needle 2, a thread take-up that pulls up the upper thread, a thread cutter that cuts off the sewing end ends of the upper thread and lower thread, a display input device 80 that serves as a display input unit that displays various information related to sewing and accepts input of various settings, a control device 90 that controls the operation of each component of the sewing machine 10, and a sewing machine frame 20 that stores or supports each component of the sewing machine 10.

In the following explanation, the horizontal direction parallel to the direction in which the bottom feed mechanism feeds the sewn material is referred to as the X-axis direction, the downstream side of the sewn material in the feed direction is referred to as the "front", and the upstream side of the feed direction is referred to as the "rear". The horizontal direction perpendicular to the X-axis direction is referred to as the Y-axis direction, the left hand side facing forward is referred to as the "left", and the right hand side is referred to as the "right". The direction perpendicular to the X-axis and Y-axis directions is referred to as the Z-axis direction, one of which is referred to as the "up" and the other as the "down".

The sewing machine frame 20 comprises a sewing machine bed portion 21 extending along the Y-axis direction, an upright body portion 22 raised from the right end portion of the sewing machine bed portion 21, and a sewing machine arm portion 23 extending to the left along the Y-axis direction from the upper end portion of the upright body portion 22.
The needle bar which holds the sewing needle 2, the presser foot 3 and the upper feed 4 are supported at the lower left end of the sewing machine arm portion 23.

A rectangular display screen of a display input device 80 is disposed on the front side of the standing body 22. The front surface of the standing body 22 and the display screen of the display input device 80, which is flush with the front surface, are inclined surfaces with the upper and left sides of the XZ plane slightly inclined backward.
The display screen of the display input device 80 is inclined as described above so that it is easily visible to a sewing machine operator working from behind facing the needle drop position of the sewing machine 10.

The upper surface of the sewing machine bed portion 21 is a smooth surface along the X-Y plane, and a needle plate (not shown) is positioned flush with the upper surface of the sewing machine bed portion 21 at the needle drop position of the sewing needle 2.

The needle up/down movement mechanism is the same as a well-known mechanism, so a detailed description will be omitted. The needle up/down movement mechanism uses a sewing machine motor 11 built into the sewing machine as a drive source and can move the needle bar up and down using a crank mechanism.

The needle swing mechanism is the same as a well-known mechanism, so a detailed description will be omitted. The needle swing mechanism includes a support frame that supports the needle bar so that it can move up and down, and a needle swing motor 15 that moves the tip of the needle bar along the Y-axis direction via the support frame.

The shuttle mechanism is a well-known mechanism and will not be described in detail here. The shuttle mechanism has a shuttle that rotates with power from the sewing machine motor 11 below the needle plate, and captures the upper thread loop from the lowering sewing needle 2 and entangles the lower thread to form a stitch on the sewn item.
The thread take-up receives power from the sewing machine motor 11 and moves up and down in the same cycle as the needle drop. The needle thread heading toward the sewing needle is hung on the thread take-up, and when the shuttlecock forms a stitch with the needle thread and the bobbin thread, the thread is pulled up to fasten the stitch.

The bottom feed mechanism is the same as a well-known mechanism, and therefore a detailed description thereof will be omitted. The bottom feed mechanism has a feed dog whose teeth appear and disappear from the opening of the needle plate, and receives reciprocating motion in the X-axis direction and reciprocating motion in the Z-axis direction from the sewing machine motor 11 and applies them to the feed dog. As a result, the feed dog performs an elliptical motion around the Y-axis whose longitudinal direction is along the X-axis direction. When the feed dog passes the upper part of the locus of the elliptical motion, the tooth tip of the feed dog moves forward while protruding upward from the opening of the needle plate, and feeds the sewn material on the needle plate forward.
The bottom feed mechanism also includes a bottom feed adjustment motor 12 that adjusts the stroke width of the reciprocating motion in the X-axis direction transmitted from the sewing machine motor 11, and the amount of feed of the workpiece by the feed dog can be adjusted as desired.

The upper feed mechanism is the same as a well-known mechanism, and therefore a detailed description thereof will be omitted. The upper feed mechanism has an upper feed that performs a feed operation by contacting the workpiece at the needle drop position from above the needle plate, and receives reciprocating motion in the X-axis direction and reciprocating motion in the Z-axis direction from the sewing machine motor 11 and applies them to the upper feed. As a result, the upper feed performs an elliptical motion around the Y-axis whose longitudinal direction is aligned with the X-axis direction. When the upper feed passes under the locus of the elliptical motion, the tip portion moves forward along the upper surface of the needle plate, feeding the workpiece on the needle plate forward.
The upper feed mechanism also includes an upper feed adjustment motor 13 that adjusts the stroke width of the reciprocating motion in the X-axis direction transmitted from the sewing machine motor 11, and the amount of feed of the workpiece by the feed dog can be adjusted as desired.
In addition, the upper feed can be manually switched between a retracted position where no feed is performed and a feed position where feed is performed, and it is possible to select whether or not to perform the upper feed. A sensor may be provided to detect whether the upper feed is located at the retracted position or the feed position, and the detection signal may be input to the control device 90.

The presser foot 3 is provided above the needle drop position of the needle plate and can press down the material to be sewn from above. The presser foot 3 is attached to the lower end of a presser bar that is supported hanging down from the lower left end of the sewing machine arm section 23. A spring pressure is applied to the presser bar within the sewing machine arm section 23, and the presser foot 3 is pressed towards the needle plate side to apply pressure to the material to be sewn.
There are a number of different types of presser foot 3, and the presser foot 3 can be replaced with an appropriate one depending on the type of sewing.
The presser bar can retract the presser foot 3 upward by a manual lever (not shown) or the presser foot motor 14. Furthermore, the presser foot motor 14 can adjust the pressing pressure of the presser foot as desired.

The thread tension device is a well-known mechanism and will not be described in detail. Although not shown in the figure, the thread tension device clamps the upper thread midway through its path and applies tension to the upper thread by clamping pressure. The thread tension device can adjust the clamping pressure using the thread tension solenoid 16, which allows any desired thread tension to be applied to the upper thread.

The thread cutting device is a well-known mechanism and will not be described in detail. The thread cutting device has a knife that operates between the needle plate and the shuttle mechanism to cut the upper and lower threads. The thread cutting device has a thread cutting solenoid 17 for operating the knife.

The display input device 80 includes a display unit 81 provided on the front side of the upright body portion 22 of the sewing machine frame 20, a touch panel 82 provided overlapping the front side of the display unit 81, and three dials 83, 84, 85 provided side by side approximately in the Y-axis direction immediately below the display unit 81. The portion of the display input device 80 consisting of the display unit 81 and the touch panel 82 corresponds to the touch operation type display input device in this embodiment, and the dials 83, 84, 85 are hardware dials corresponding to the hardware operation unit.
The display unit 81 is composed of a liquid crystal display or an organic EL (Electro Luminescence) display, and displays an input screen G1, which will be described later, under display control by the control device 90. The touch panel 82 detects the position of a touch input by an operator of the sewing machine, and functions as an input detection unit that detects an input operation on the input screen G1.
The three dials 83 , 84 , 85 each have an internal encoder 831 , 841 , 851 , and the amount of rotation performed by the operator is input to the control device 90 through the encoders 831 , 841 , 851 .

[Sewing machine control system]
Next, the configuration of a control system of the sewing machine 10 will be described with reference to FIG.
The control device 90 of the sewing machine 10 includes a ROM 92 that stores various programs for performing various controls and processes described below, sewing pattern data for performing various stitches, and other various setting data, a CPU 91 that executes the various programs in the ROM 92, a RAM 93 that serves as a working area when executing the various programs, and an input/output interface 94 and an output interface 95 that are connected to the CPU 91, ROM 92, and RAM 93 via buses.

The output interface 95 is connected to the sewing machine motor 11, the bottom feed adjustment motor 12, the top feed adjustment motor 13, the presser motor 14, the needle swing motor 15, the thread tension solenoid 16, and the thread cutting solenoid 17 via drive circuits 11a, 12a, 13a, 14a, 15a, 16a, and 17a. The CPU 91 can control the operations of these components.
The input/output interface 94 is connected to each component of the display/input device 80 and a power switch 96 .

The sewing machine 10 uses the control device 90 to control the amount of forward and backward feed by the bottom feed adjustment motor 12 and the amount of left and right needle swing by the needle swing motor 15, allowing the needle to drop at any position on the X-Y plane on the material being sewn.
The sewing pattern data is made up of data indicating a plurality of needle drop positions within an XY plane that is determined according to the sewing pattern.
The control device 90 reads the sewing pattern data and controls the bottom feed adjustment motor 12 and the needle swing motor 15 to perform sewing that forms stitches in accordance with the sewing pattern.

[Display control of display input device]
The following describes the display control of the display input device 80 performed by the control device 90. The display control of the display input device 80 and the processing performed by input described below are all performed by the CPU 91 of the control device 90 executing a program in the ROM 92.

Figure 4 is an explanatory diagram showing a display example of the input screen G1 displayed on the display unit 81 of the display input device 80, and Figure 5 is an explanatory diagram showing the division of multiple display areas of the input screen G1 with virtual lines. In these explanatory diagrams showing display examples and the explanatory diagrams showing other display examples described below, the top, bottom, left, and right on the paper surface approximately correspond to the top, bottom, left, and right on the sewing machine 10.

As shown in the figure, the input screen G1 is generally a vertically elongated rectangle and is divided into a first region R1 extending across the entire width of the top of the screen from left to right, a second region R2 extending across the entire width of the top of the screen from left to right below that, third to fifth regions R3 to R5 located below that, and a sixth region R6 extending across the entire width of the bottom of the screen from left to right.
The third to fifth regions R3 to R5 are vertically elongated rectangular regions that divide the area between the second region R2 and the sixth region R6 into thirds, with the third region R3 on the left, the fourth region R4 in the middle, and the fifth region R5 on the right.
5, the third to fifth regions R3 to R5 are divided into three equal parts in the left-right direction, but this is not limited thereto, and the ratio of each part can be increased or decreased. For example, the left-right width of the central fourth region R4 may be changed within a range of 1/4 to 1/2 of the overall width, and the left-right widths of the third region R3 and the fifth region R5 on both sides of the central fourth region R4 may be made equal.

In the first area R1, a support button B11, a settings button B12, a sewing button B13, a history button B14, and a portal button B15, each of which is displayed as a character string, are arranged in order from left to right for switching to various input screens.

The history button B14 is a button for switching the display to a history screen (not shown). The history screen is an input screen for calling up sewing pattern data and record data related to settings at the time of sewing for a plurality of sewing patterns that have been sewn in the past.
The portal button B15 is a button for switching the display to a browser screen for connecting to a portal site of the sewing machine 10 via a network line.

In the second area R2, a presser foot candidate display frame W21 consisting of a pattern and text display for switching between various display screens, a sewing pattern selection button B21, a sewing pattern setting button B22, and a cycle selection button B23 are arranged in order from the left as an operation section.

The presser foot candidate display frame W21 displays the type of presser foot 3 that is suitable for the currently selected sewing pattern. For example, in the example of Figure 4, pattern information and text information are displayed indicating that presser foot A and presser foot B are suitable for the currently selected sewing pattern.

The sewing pattern selection button B21 has a substantially rectangular contact range set, and when this contact range is touched, the display switches to a sewing pattern selection screen. Multiple types of sewing patterns are registered in the control device 90, and each sewing pattern is assigned a pattern number. When a pattern number is selected and confirmed on the selection screen, the selected pattern number is displayed within the substantially rectangular contact range of the selection button B21.

The sewing pattern setting button B22 has a circular contact range set, and an icon indicating that it is a setting button is displayed inside the circular contact range. When the user touches within the contact range of this setting button B22, the display switches to a specified setting screen. From this setting screen, settings related to the sewing pattern other than the parameters set by buttons B31 to B53, which will be described later, can be made. For example, from this setting screen, pattern editing such as flipping the sewing pattern upside down or leftside to right can be performed.

The cycle selection button B23 has a circular contact range set, and an icon indicating that it is a cycle selection button is displayed inside the range. When the user touches within the contact range of the cycle selection button B23, the user can set whether to perform single-shot sewing, which sews one sewing pattern, or continuous sewing, which sews repeatedly. When single-shot sewing is set for this cycle selection button B23, the number "1" is displayed inside the icon, and when repeated sewing is selected, the number inside the icon is erased.

In each of the third area R3 and the fifth area R5, three buttons are arranged vertically as operation units for making predetermined settings for the sewing pattern.
In the third area R3, a sewing start process setting button B31, a thread tension setting button B32, and a sewing end process setting button B33 are arranged in this order from the top.
In the fifth area R5, a top feed setting button B51, a presser lifting setting button B52, and a thread cutting setting button B53 are arranged in order from the top.
A circular contact range is set for each of these various setting buttons B31, B32, B33, B51, B52, and B53, and an icon is displayed inside the range as a content display section showing the content to be input from each setting button.
In addition, on the outer lower part of the various setting buttons B31, B32, B33, B51, B52, B53, there are respectively arranged setting information display sections W31, W32, W33, W51, W52, W53 which serve as content display sections showing the content to be entered from each setting button and its setting value or setting status in text information.

The sewing start process setting button B31 is a button for selecting whether or not to perform densification stitching at the start end of sewing and the type of densification stitching. For example, by repeatedly touching within the contact range of the sewing start process setting button B31, the settings can be switched between backstitching, welt stitching, and no densification stitching.

The thread tension setting button B32 is a button for arbitrarily setting the thread tension of the thread tension device using the thread tension solenoid 16. When the touch range of the thread tension setting button B32 is touched, the thread tension input screen G21 (Figure 6) is displayed, and the thread tension can be set by inputting data on the screen G21 or by rotating the dial 84.

Details are as follows:
FIG. 6 is an explanatory diagram showing an example of a display of the thread tension input screen G21 displayed on the display unit 81 of the display input device 80. As shown in FIG.
The input screen G21 displays a thread tension setting information display section W32, a software dial D11, and an illustration display A10 simulating an upper thread A11 and a lower thread A12.
7, when the software dial D11 is touched with a finger or the like and turned clockwise, or when the dial 84 is turned clockwise, the value displayed in the setting information display section W32 (thread tension setting) increases, and at the same time, the thread tension of the upper thread A11 in the illustration display A10 changes to a relatively stronger state (the node of the upper thread A11 and the lower thread A12 rises). The thread tension setting (W32) indicates the relative magnitude of the upper thread tension to the lower thread tension, with a positive value indicating that the upper thread tension is greater than the lower thread tension, and a negative value indicating that the upper thread tension is less than the lower thread tension.

In addition, when the software dial D11 is touched with a finger or the like and turned counterclockwise, or when the dial 84 is turned counterclockwise, the numerical value displayed in the setting information display section W32 decreases, and at the same time, the thread tension of the upper thread A11 in the illustration display A10 changes to a relatively weaker state (the node of the upper thread A11 and the lower thread A12 descends).
The control device 90 controls the change in the display of the input screen G21 in response to the above input operations, and at the same time, executes and controls the adjustment of the thread tension according to the set value (W32). However, if the presser foot 3 is raised, when the presser foot 3 is lowered, the control device 90 executes and controls the adjustment of the thread tension according to the set value (W32) of the thread tension.

The end-of-sewing setting button B33 is a button for selecting whether or not to perform densification stitching at the end of the sewing and the type of densification stitching. For example, by repeatedly touching within the contact range of the end-of-sewing setting button B33, the settings can be switched between backstitching, welt stitching, and no densification stitching.

The top feed setting button B51 is a button for setting whether or not top feed is performed by the top feed 4 and the top feed amount (the difference value relative to the bottom feed amount by the feed dog). Touching within the contact range of the top feed setting button B51 switches between a setting with or without top feed being performed. Furthermore, when top feed is set to be performed, the top feed amount input screen G22 (Figure 8) is displayed, and the top feed amount can be set by inputting information on the screen G22 or by rotating the dial 84.

Details are as follows:
FIG. 8 is an explanatory diagram showing an example of a display of an input screen G22 for inputting the feed amount of the sewing workpiece, which is displayed on the display section 81 of the display input device 80. As shown in FIG.
The input screen G22 displays the smart feed setting information display section W51, the software dial D12, and an illustration display A20 showing the relationship between the top feed amount and the bottom feed amount. Display A21 shows the top feed 4, display A22 shows the fabric, display A23 shows the center line in the feed direction, square display A24 shows an image of the fabric according to the bottom feed amount, and square display A25 shows an image of the fabric according to the top feed amount. Although not shown, the square display A24 is gray and the square display A25 is blue, and in FIG. 8, the smart feed setting value is 0, so they are perfectly overlapped.
When the software dial D12 shown in Fig. 8 is touched with a finger or the like and turned clockwise, or when the dial 84 is turned clockwise, the value displayed in the setting information display section W51 (the setting value of smart feed) increases, and at the same time, the square display A25 in the illustration display A20 shifts downward (toward the viewer) relative to the square display A24. This indicates that the top feed amount has become proportionally larger. The setting value of smart feed indicates the relative size of the top feed amount to the bottom feed amount, with a positive value indicating that the top feed amount is larger than the bottom feed amount, and a negative value indicating that the top feed amount is smaller than the bottom feed amount.

Furthermore, when the software dial D12 is touched with a finger or the like and turned counterclockwise, or when the dial 84 is turned counterclockwise, the value displayed in the setting information display section W51 (the setting value of smart feed) decreases, and at the same time, the square display A25 in the illustration display A20 shifts upward (toward the back) relative to the square display A24, indicating that the upward feed amount has become proportionally smaller.
The control device 90 controls the change in the display of the input screen G22 in response to the above input operations, and at the same time, executes and controls the adjustment of the feed amount of the sewing workpiece in accordance with the smart feed setting value (W51). However, if the fabric presser foot 3 is raised, the control device 90 executes and controls the adjustment of the feed amount of the sewing workpiece when the fabric presser foot 3 is lowered.

The presser foot lifting setting button B52 is a button that sets whether or not to automatically lift the presser foot 3 and release the sewn material when sewing of the sewing pattern is completed. By touching within the contact range of the presser foot lifting setting button B52, the setting for whether or not to automatically lift the presser foot 3 can be switched.

The thread cutting setting button B53 is a button for setting whether or not to automatically perform thread cutting using the thread cutting device when sewing of the sewing pattern is completed. By touching within the contact range of the thread cutting setting button B53, the setting for whether or not to perform automatic thread cutting can be switched.

In the fourth area R4, a pattern image display frame W41 that displays an image of the currently selected sewing pattern, and a baseline position setting button B42 as an operation unit are arranged in order from the top.

A sewing pattern image consisting of the design of the currently selected sewing pattern is displayed in the pattern image display frame W41. This sewing pattern image is a moving image that is linked to the sewing operation, and the needle drop position in the left-right direction where the current needle drop is taking place is displayed at the top of the image. In addition, below the needle drop position, the stitch that will be formed at the needle drop position where the needle drop will take place next is displayed. This sewing pattern image is a moving image in which the stitch moves upward by one stitch each time a needle drop is made.

The baseline position setting button B42 has a circular contact range set thereon, and an icon is displayed inside the range as a content display section showing the content to be input via the baseline position setting button B42.
The base line is a reference line of the sewing pattern that is aligned in the cloth feed direction, and the needle swing amount of each needle drop position of the sewing pattern is determined based on the base line.
When a touch is made within the contact range of this baseline position setting button B42, a baseline position input screen G23 (FIG. 9) is displayed, and the baseline position can be set by inputting data on the screen G23 or by rotating the dial 84.

Details are as follows:
FIG. 9 is an explanatory diagram showing an example of a display of an input screen G23 for inputting a sewing reference position displayed on the display unit 81 of the display input device 80. As shown in FIG.
The input screen G23 displays a setting information display section W42 for the baseline position, a software dial D13, an illustration display A30 showing the baseline position, and setting buttons B61 and B62. Display A31 displays the settable range, display A32 displays the baseline, and display A33 displays the sewing pattern.
9 is turned clockwise with a finger or the like, or the dial 84 is turned clockwise, the numerical value (baseline position setting value) displayed in the setting information display section W42 increases, and at the same time, the baseline display A32 in the illustration display A30 is shifted to the right together with the sewing pattern display A33. This indicates that the baseline position has moved to the right. For example, a positive value of the baseline position setting value indicates that the baseline is to the right of the center, and a negative value indicates that the baseline is to the left of the center.
Furthermore, when the setting button B62 is touched with a finger or the like, the baseline is set to the rightmost end, and the numerical value in the setting information display section W42 and the illustration display A30 change accordingly.

Furthermore, when the software dial D13 is touched with a finger or the like and turned counterclockwise, or when the dial 84 is turned counterclockwise, the numerical value (the baseline position setting value) displayed in the setting information display section W42 decreases, and at the same time, the baseline display A32 in the illustration display A30 is shifted to the left together with the sewing pattern display A33, indicating that the baseline position has moved to the left.
Furthermore, when the setting button B61 is touched with a finger or the like, the baseline is set to the leftmost end, and the numerical value in the setting information display section W42 and the illustration display A30 change accordingly.
The control device 90 controls the change of the display of the input screen G23 in response to the above input operations, and at the same time, executes and controls the adjustment of the sewing reference position in accordance with the set value (W42) of the baseline position. However, if the presser foot 3 is raised, the control device 90 executes and controls the adjustment of the sewing reference position when the presser foot 3 is lowered.

In the sixth area R6, the presser pressure display section W61, which numerically displays the set value of the pressure applied by the presser foot 3, the stitch width display section W62, which numerically displays the set value of the left-right width of the needle swing in the sewing pattern, and the stitch length display section W63, which numerically displays the set value of the spacing (stitch pitch) between each stitch in the fabric feed direction, are arranged in order from the left.

The presser pressure display W61, stitch width display W62 and stitch length display W63 are disposed immediately above the dials 83, 84 and 85, respectively.
The pressure is set based on the input rotation amount of the dial 83 detected by the encoder 831, and the input pressure setting value is displayed numerically on the pressure display section W61.
The stitch width is set based on the input rotation amount of the dial 84 detected by the encoder 841, and the input stitch width setting value is displayed numerically in the stitch width display section W62.
The stitch length is set based on the input rotation amount of the dial 85 detected by the encoder 851, and the input stitch width setting value is displayed numerically on the stitch width display section W63.

[Summary, effects, etc.]
As described above, the control device 90 controls so that a predetermined operation item can be inputted from either the touch operation type display input device (81, 82) or the hardware operation unit (84).
Therefore, the user can select either one of the touch operation display input devices (81, 82) or the hardware operation unit (84) as necessary to perform input operations, improving operability.
By applying a dial that produces a click-like tactile sensation according to a constant operating pitch as the hardware operating section (84), the user can easily recognize the amount of operation by the tactile sensation even when operating blindly, improving operability.
In addition, by applying a dial that generates a clicking sound according to a certain operation pitch as the hardware operation unit (84), the user can easily recognize the amount of operation by hearing even when operating blindly, improving operability. The operation sound may be electrically amplified and output from a speaker, and the volume may be adjusted to an easy-to-hear level.
On the other hand, when a touch-operated display input device (81, 82) is selected as the operating means, the screen area and display variability of the display unit 81 can be utilized to display a larger area occupied by the software operating unit, making it easier for the user to perform fine input operations, thereby improving operability.

In the above embodiment, the specified operation items are adjustments of the set values of the sewing conditions, and the adjustments are three items: thread tension adjustment, sewing reference position adjustment, and feed amount adjustment of the sewn material. This improves the convenience of setting the sewing device. However, the scope of application of the present invention is not limited to these operation items.

The control device 90 also changes the operation result display ((A10, W32), (A20, W51) or (A30, W42)) of the touch-operated display input device (81, 82) in real time in response to the input operation. Therefore, the user can easily recognize the current settings.

The control device 90 changes the display of the operation result for the specified operation item in the same way whether the input operation is from the touch-type display input device (81, 82) or the hardware operation unit (84). Since the real-time operation result is displayed in the same way by either operation means, the user can select either one without any difference in merit.
In the above embodiment, the operation result display includes a numerical value display (W32, W51 or W42) that increases or decreases according to the amount of operation, and an illustrated display (A10, A20 or A30) that illustrates the sewing conditions and moves according to the amount of operation. The user can accurately recognize the numerical value display and intuitively recognize the illustration display, improving operability.

In the above embodiment, the software dials (D11, D12, D13) are arc-shaped with a larger diameter than the hardware dial (84). This improves the operability of the software dial (D11) and makes it easier to secure space for the hardware dial (84).
