Detailed Description

[ outline of embodiments of the invention ]

Next, a sewing device according to the present invention will be described with reference to the drawings. 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 includes: a needle vertical moving mechanism which uses the sewing machine motor 11 as a driving source and provides vertical moving action to the needle bar holding the sewing needle 2; a lower feeding mechanism which utilizes the power of the sewing machine motor 11 to convey the sewed object from the lower part of the needle plate through the feeding teeth; an upper feeding mechanism which conveys the sewed object from the upper feeding part 4 contacted with the upper part of the sewed object by the power of the sewing machine motor 11; a kettle mechanism; a cloth presser foot 3 for pressing the sewed object on the needle plate from the upper part; a needle swing mechanism which makes the needle bar move arbitrarily in the direction orthogonal to the cloth feeding direction; a thread regulator device which gives thread tension to the upper thread passing through the sewing needle 2; a thread take-up lever for lifting the upper thread; a thread cutting device for cutting the sewing end of the upper thread and the lower thread; a display input device 80 as a display input unit for displaying various information related to sewing and receiving input of various settings; a control device 90 for controlling the operation of each component of the sewing machine 10; and a sewing machine frame 20 which accommodates or supports each structure of the sewing machine 10.

In the following description, a horizontal direction parallel to a direction in which the lower feed mechanism conveys the workpiece is referred to as an X-axis direction, a downstream side of the workpiece in the feed direction is referred to as "front", and an upstream side of the workpiece in the feed direction is referred to as "rear". The direction horizontal and orthogonal to the X-axis direction is the Y-axis direction, the left-hand side facing forward is the "left", and the right-hand side is the "right". In addition, a direction orthogonal to the X-axis direction and the Y-axis direction is a Z-axis direction, one of which is "up" and the other is "down".

The sewing machine frame 20 has: a sewing machine base part 21 extending along the Y-axis direction; a vertical body part 22 rising from a right end part of the sewing machine base part 21; and a sewing machine arm 23 projecting leftward in the Y-axis direction from an upper end of the longitudinal body portion 22.

A needle bar for holding the sewing needle 2, the cloth presser foot 3 and the upper feed portion 4 are supported at the lower part of the left end of the arm portion 23 of the sewing machine.

A rectangular display screen of the display input device 80 is disposed on the front surface side of the vertical body section 22. The front surface of the vertical body section 22 and the display screen of the display input device 80 that is flush with the front surface are constituted by inclined surfaces that slightly incline rearward on the upper side and the left side of the X-Z plane.

The display screen of the display input device 80 is inclined as described above, so that the operator of the sewing machine who performs work by facing the needle drop position with respect to the sewing machine 10 from the rear can easily observe the display screen.

The upper surface of the sewing machine base part 21 is a smooth surface along the X-Y plane, and a needle plate not shown is disposed at the needle drop position of the sewing needle 2 in a plane with the upper surface of the sewing machine base part 21.

Since the needle vertical movement mechanism is the same as a known mechanism, a detailed description thereof will be omitted. The needle up-down moving mechanism uses a sewing machine motor 11 built in the sewing machine as a driving source, and can move the needle bar up and down through a crank mechanism.

Since the needle swing mechanism is the same as a known mechanism, a detailed description thereof is omitted. The needle swing mechanism includes: a support frame which supports the needle bar in a manner of moving up and down; and a needle swing motor 15 for arbitrarily moving the tip end of the needle bar in the Y-axis direction via the support frame.

The tank mechanism is the same as a known mechanism, and therefore, a detailed description thereof is omitted. The pot mechanism has a pot which is rotated by power from a sewing machine motor 11 at the lower side of a needle plate, catches a loop of an upper thread from a descending sewing needle 2 and winds the upper thread with the lower thread, and forms a stitch on a sewing object.

The take-up lever is moved up and down by power from a sewing machine motor 11 in a cycle identical to the needle drop. The upper thread towards the sewing needle is arranged on the thread take-up lever frame, and the upper thread is lifted by the kettle when the stitches of the upper thread and the lower thread are formed so as to fasten the stitches.

Since the lower feed mechanism is the same as a known mechanism, a detailed description thereof is omitted. The lower feed mechanism has feed teeth for advancing and retracting the tooth tips from the opening of the needle plate, and the reciprocating motion in the X-axis direction and the reciprocating motion in the Z-axis direction are taken out from the sewing machine motor 11 and applied to the feed teeth. Thereby, the feed teeth perform an oblong motion around the Y axis in the X axis direction in the longitudinal direction. When the feed teeth pass through the upper part of the orbit of the oblong motion, the tooth tops move forward while protruding upward from the opening part of the needle plate, and the sewing object on the needle plate is conveyed forward.

The lower feed mechanism further includes a lower feed adjustment motor 12, and the lower feed adjustment motor 12 adjusts the stroke width of the reciprocating motion in the X-axis direction transmitted from the sewing machine motor 11, and can arbitrarily adjust the feed amount of the workpiece by the feed teeth.

The upper feed mechanism is the same as a known mechanism, and therefore, a detailed description thereof is omitted. The upper feed mechanism has an upper feed portion which is contacted with the sewed object at the needle drop position from the upper side of the needle plate to perform a feed action, and takes out the reciprocating action in the X-axis direction and the reciprocating action in the Z-axis direction from the sewing machine motor 11 to provide the reciprocating action to the upper feed. Thereby, the upper feed portion performs an oblong motion around the Y axis in the X axis direction in the longitudinal direction. When the upper feed portion passes through the lower portion of the orbit of the oblong motion, the front end portion moves forward along the upper surface of the needle plate, and the sewn object on the needle plate is conveyed forward.

The upper feed mechanism further includes an upper feed adjustment motor 13, and the upper feed adjustment motor 13 adjusts the stroke width of the reciprocating motion in the X-axis direction transmitted from the sewing machine motor 11, and can arbitrarily adjust the feed amount of the workpiece by the feed teeth.

The upper feed unit can be manually switched between a retracted position where feeding is not performed and a feed position where feeding is performed, and can be selected whether or not upper feeding is performed. A sensor for detecting which position the upper feeding portion is at, the retracted position or the feeding position may be provided, and a detection signal thereof may be input to the control device 90.

The cloth presser foot 3 is provided above the needle fall position of the needle plate and can press the sewed object from above. The cloth presser foot 3 is attached to the lower end portion of a presser foot bar supported to hang down from the lower portion of the left end of the sewing machine arm 23. The presser bar is provided with spring pressure in the sewing machine arm 23, and the cloth presser 3 is pressed toward the needle plate side to provide presser pressure to the object to be sewn.

The cloth presser foot 3 has a plurality of types, and can be replaced with an appropriate cloth presser foot 3 according to the type of sewing.

The presser bar can retract the cloth presser 3 upward by a manual lever or a presser motor 14, not shown. The presser foot motor 14 can arbitrarily adjust the presser foot pressure of the cloth presser foot.

Since the wire adjuster device is the same as a known mechanism, a detailed description thereof is omitted. The thread adjusting device is not shown in the drawings, but holds the upper thread in the middle of the path of the upper thread and applies tension to the upper thread by the holding pressure. The thread adjuster device can adjust the clamping pressure by the thread adjuster solenoid 16, thereby giving an arbitrary thread tension to the upper thread.

Since the thread cutting device is the same as a known mechanism, a detailed description thereof is omitted. The thread cutting device is provided with a cutter working between the needle plate and the kettle mechanism, and is used for cutting off the upper thread and the lower thread. The thread cutting device has a thread cutting solenoid 17 for operating the cutter.

The display input device 80 includes: a display part 81 provided on the front surface side of the longitudinal body part 22 of the sewing machine frame 20; a touch panel 82 provided so as to overlap the front surface side of the display section 81; and three rotating disks 83, 84, 85 arranged substantially in the Y-axis direction immediately below the display portion 81. The portion of the display input device 80 including the display section 81 and the touch panel 82 corresponds to a touch operation type display input device in the present embodiment, and the reels 83, 84, and 85 are hardware reels corresponding to hardware operation sections.

The display unit 81 is composed of a liquid crystal display and an organic el (electro luminescence), and displays an input screen G1 described later by display control performed by the control device 90. The touch panel 82 functions as an input detection unit that detects a contact input position of an operator of the sewing machine and detects an input operation on the input screen G1.

The three rotation disks 83, 84, and 85 each include an encoder 831, 841, and 851, and the rotation operation amount of the operator is input to the control device 90 via the encoders 831, 841, and 851.

The CPU 91 can control the operations thereof.

The input/output interface 94 is connected to the power switch 96 and the respective configurations of the display input device 80.

The sewing machine 10 is capable of controlling the forward and backward feed amount by the lower feed adjustment motor 12 and the left and right needle swing amount by the needle swing motor 15 by the control device 90, and dropping a needle at an arbitrary position on the X-Y plane with respect to a workpiece.

The sewing pattern data is composed of data representing a plurality of needle drop positions in an X-Y plane determined according to the sewing pattern.

The control device 90 can read the sewing pattern data, control the lower feed adjusting motor 12 and the needle swing motor 15, and perform sewing for forming stitches corresponding to the sewing pattern.

[ display control of display input device ]

The display control of the display input device 80 by the control device 90 will be described. The display control and input processing performed by the display input device 80 described below are all performed by the CPU 91 of the control device 90 executing a program in the ROM 92.

Fig. 4 is an explanatory view showing an example of display of the input screen G1 displayed on the display unit 81 of the display input device 80, and fig. 5 is an explanatory view showing division of a plurality of display areas of the input screen G1 by imaginary lines. In the explanatory drawings showing these display examples and the explanatory drawings showing other display examples described later, the upper, lower, left, and right sides of the paper surface substantially coincide with the upper, lower, left, and right sides of the sewing machine 10.

As shown in the drawing, the input screen G1 is rectangular in overall length and is divided into a first region R1 extending over the entire left-right width of the upper end of the screen, a second region R2 extending over the entire left-right width of the lower portion of the screen, third to fifth regions R3 to R5 disposed below the first region, and a sixth region R6 extending over the entire left-right width of the lower end of the screen.

The third to fifth regions R3 to R5 are vertically long rectangular regions each obtained by dividing the region between the second region R2 and the sixth region R6 into three parts in the left-right direction, and the left side is the third region R3, the center is the fourth region R4, and the right side is the fifth region R5.

The third to fifth regions R3 to R5 are trisected in the left-right direction in the example of fig. 5, but are not limited thereto, and the ratios may be increased or decreased. For example, the left and right widths of the central fourth region R4 may be changed to be 1/4 to 1/2 of the entire width, and the left and right widths of the third region R3 and the fifth region R5 may be made equal on both sides.

In the first region R1, a support button B11, a setting button B12, a sewing button B13, a history button B14, and a portal button B15 for switching to various input screens are arranged in order from left to right.

These buttons B11 to B15 can be operated by touching the button positions to perform button input. Further, by sliding the first region R1 to the left and right, the positions of the buttons B11 to B15 can be scrolled.

The support button B11 is a button for switching the display to a support screen on which an operation manual or the like of the sewing machine 10 is displayed.

The setting button B12 is a button for switching the display to a setting screen for setting the brightness of a not-shown work light, the sound volume of a not-shown speaker, and the like with respect to the surrounding environment of the sewing machine 10.

The sewing button B13 is a button for switching the display to the input screen G1 of fig. 4. The input screen G1 enables various settings related to sewing.

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 a plurality of sewing patterns which have been sewn in the past and for calling the sewing pattern data and the record data related to the setting of the sewing pattern data at the time of sewing.

The portal button B15 is a button for switching display to a browser screen for connection to the web portal of the sewing machine 10 via a network line.

In the second region R2, a cloth presser foot candidate display frame W21 configured by graphic and character string display for switching to various display screens, a selection button B21 of a sewing pattern as an operation portion, a setting button B22 of the sewing pattern, and a circulation selection button B23 are arranged in order from the left.

In the cloth presser candidate display frame W21, the type of the cloth presser 3 suitable for the sewing pattern currently selected is displayed. For example, in the example of fig. 4, graphic information and character information suitable for the selected sewing pattern are displayed for the cloth presser a and the cloth presser B.

The sewing pattern selection button B21 has a substantially rectangular contact range, and if the contact range is touched, the display is switched to the sewing pattern selection screen. A plurality of types of sewing patterns are registered in the control device 90, and a pattern number is set for each sewing pattern. If a pattern number is selected on the selection screen, the selected pattern number is displayed within the substantially rectangular contact range of the selection button B21.

The setting button B22 of the sewing pattern has a circular contact range, and an icon indicating the setting button is displayed on the inner side. If the setting button B22 is touched within the contact range, the display is switched to a predetermined setting screen. From this setting screen, settings relating to sewing patterns other than the parameters set by the buttons B31 to B53 described later can be made. For example, pattern editing such as vertical inversion and horizontal inversion of the sewing pattern can be performed from the setting screen.

The cycle selection button B23 has a circular contact range set therein, and an icon indicating that the button is a cycle selection button is displayed inside the button. If the touch cycle selection button B23 is within the contact range, it can be set whether to perform single-shot sewing or continuous sewing, wherein the single-shot sewing is performed in a single sewing pattern, and the continuous sewing is repeated. When the single-shot sewing is set for the loop selection button B23, the number of "1" is displayed inside the icon, and when the repeated sewing is being selected, display control is performed to delete the number inside the icon.

Three buttons serving as operation sections for setting a predetermined sewing pattern are arranged vertically in the third region R3 and the fifth region R5, respectively.

In the third region 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 above.

In the fifth region R5, the upper feed setting button B51, the presser foot raising setting button B52, and the tangent line setting button B53 are arranged in this order from above.

The various setting buttons B31, B32, B33, B51, B52, and B53 have circular contact ranges, and icons serving as content display units that display contents input from the setting buttons are displayed on the inner sides of the contact ranges.

In addition, setting information display units W31, W32, W33, W51, W52, and W53 as content display units are disposed on the outer lower portions of the various setting buttons B31, B32, B33, B51, B52, and B53, respectively, and display the contents input from the setting buttons and the setting values or setting states thereof by character information.

The sewing start processing setting button B31 is a button for selecting whether or not to execute sewing stop at the sewing start end and the type of sewing stop. For example, by repeatedly touching the contact range of the sewing start processing setting button B31, the settings of return sewing, sewing stop of the band, and sewing non-stop can be switched.

The wire tension setting button B32 is a button for arbitrarily setting the wire tension of the wire adjuster device generated by the wire adjuster solenoid 16. If the touch range of the line tension setting button B32 is touched, a line tension input screen G21 (fig. 6) is displayed, and the line tension can be set by an input operation to the screen G21 or an input operation by rotation of the dial 84.

The details are as follows.

Fig. 6 is an explanatory diagram showing an example of a display of the input screen G21 for the line tension displayed on the display unit 81 of the display input device 80.

On the input screen G21, a setting information display unit W32 of the line controller, a software wheel D11, and an illustration display a10 simulating an upper line a11 and a lower line a12 are displayed.

As shown in fig. 7, if the software dial D11 is touched by a finger or the like to rotate clockwise or the dial 84 is rotated clockwise, the numerical value (the set value of the wire adjuster) displayed on the setting information display portion W32 increases, and at the same time, the line tension of the upper line a11 is changed to a state in which the line tension of the upper line a11 is relatively increased in the illustration display a10 (the knotting point of the upper line a11 and the lower line a12 rises). The set value (W32) of the thread adjuster shows the magnitude of the relativity of the tension of the upper thread with respect to the tension of the lower thread, positive is a tension of the upper thread greater than that of the lower thread, and negative is a tension of the upper thread less than that of the lower thread.

Further, if the software dial D11 is touched by a finger or the like to rotate counterclockwise or rotate the dial 84 counterclockwise, the numerical value displayed on the setting information display portion W32 decreases, and the state where the line tension of the upper line a11 is relatively weakened is changed in the illustration display a10 (the knotting point of the upper line a11 and the lower line a12 lowers).

The control device 90 controls the change in the display of the input screen G21 corresponding to the above input operation, and performs adjustment of the line tension so as to control the line tension to be actually set to the set value (W32). However, when the cloth presser 3 is raised, the control device 90 performs control to adjust the thread tension according to the set value (W32) of the thread adjuster after the cloth presser 3 is lowered.

The sewing end processing setting button B33 is a button for selecting whether or not to execute sewing and a type of stopping sewing at the end of sewing. For example, the settings of the return sewing, the sewing stop of the band, and the non-stop sewing can be switched by repeatedly touching the contact range of the sewing end processing setting button B33.

The top feed setting button B51 is a button for setting the presence or absence of top feed by the top feed unit 4 and the top feed amount (the difference value between the bottom feed amount and the feed tooth). If the upper feed setting button B51 is touched within the contact range, the setting of the presence or absence of the execution of the upper feed is switched. When the execution of the top feed is set, the input screen of the top feed amount is displayed, and the top feed amount can be set by an input operation on the screen or an input operation by the rotation of the dial 84.

The details are as follows.

Fig. 8 is an explanatory diagram showing an example of a display of an input screen G22 for displaying the feed amount of the workpiece on the display unit 81 of the display input device 80.

On the input screen G22, an intelligent feed setting information display unit W51, a software dial D12, and an illustration display a20 showing the relationship between the upper feed amount and the lower feed amount are displayed. Display a21 shows the upper feed section 4, display a22 shows the cloth, display a23 shows the feed direction center line, square display a24 shows the image of the cloth by the lower feed amount, and square display a25 shows the image of the cloth by the upper feed amount. Although not shown, the square display a24 is gray and the square display a25 is blue, and the set values of the smart feeds in fig. 8 are exactly coincident with each other because they are 0.

If the software dial D12 shown in fig. 8 is touched by a finger or the like to rotate clockwise or the dial 84 is rotated clockwise, the numerical value (the set value of the smart feed) displayed on the setting information display portion W51 increases, and the state in which the square display a25 is shifted downward (toward the near end) with respect to the square display a24 is changed in the illustration display a 20. Thereby indicating that the upper feed amount is proportionally larger. The set value of the smart feed shows the magnitude of the relativity of the upper feed amount with respect to the lower feed amount, and a positive value is that the upper feed amount is larger than the lower feed amount, and a negative value is that the upper feed amount is smaller than the lower feed amount.

Further, if the software dial D12 is touched by a finger or the like to rotate counterclockwise or the dial 84 is rotated counterclockwise, the numerical value (smart feed setting value) displayed on the setting information display portion W51 decreases, and the state in which the square display a24 is shifted upward (distal end) from the square display a25 is changed in the illustration display a 20. Thereby indicating that the upper feed amount becomes proportionally smaller.

The control device 90 controls the change of the display of the input screen G22 corresponding to the above input operation, and at the same time, controls the adjustment of the feed amount of the workpiece according to the setting value (W51) of the smart feeding. However, when the cloth presser 3 is lifted, the adjustment for controlling the feed amount of the workpiece is performed after the cloth presser 3 is lowered.

The presser foot lift setting button B52 is a button for setting whether or not to automatically raise the cloth presser foot 3 and release the workpiece when the sewing of the sewing pattern is completed. If the contact range of the presser foot lifting setting button B52 is touched, the setting of whether the automatic cloth presser foot 3 is lifted can be switched.

The thread cutting setting button B53 is a button for setting whether or not to automatically perform thread cutting by the thread cutting device when sewing of the sewing pattern is completed. If the contact range of the tangent setting button B53 is touched, the setting of the presence or absence of automatic tangent execution can be switched.

In the fourth region R4, a pattern image display frame W41 for displaying an image of a sewing pattern currently being selected and a base line position setting button B42 as an operation unit are arranged in order from the top.

A sewing pattern image composed of the pattern of the currently selected sewing pattern is displayed in the pattern image display box W41. The sewing pattern image is a dynamic image linked with the sewing action, and the needle dropping position in the left and right directions where the needle dropping is currently performed is displayed at the upper end part of the image. Further, a stitch formed at the needle falling position where the needle is subsequently dropped is displayed below the needle falling position. The sewing pattern image is composed of a dynamic image in which stitches of a stitch amount move upward every time one stitch is dropped.

The base line position setting button B42 has a circular contact range set therein, and icons serving as a content display section for displaying the content input from the base line position setting button B42 are displayed on the inner side thereof.

The base line is a reference line of the sewing pattern along the cloth feeding direction, and the needle swing amount at each needle drop position of the sewing pattern is determined using the base line as a reference.

If the contact range of the baseline position setting button B42 is touched, a baseline position input screen G23 (fig. 9) is displayed, and the baseline position can be set by an input operation on the screen G23 or an input operation by rotation of the dial 84.

The details are as follows.

Fig. 9 is an explanatory diagram showing an example of display of the input screen G23 for the sewing reference position displayed on the display unit 81 of the display input device 80.

On the input screen G23, a setting information display unit W42 for the base line position, a software wheel D13, an illustration display a30 showing the base line position, and setting buttons B61 and B62 are displayed. Display a31 shows the range that can be set, display a32 shows the baseline, and display a33 shows the sewing pattern.

If the dial 84 is rotated clockwise or rotated clockwise by touching the software dial D13 shown in fig. 9 with a finger or the like, the display a32 changed to the base line in the illustration display a30 is shifted to the right along with the display a33 of the sewing pattern while the numerical value (the set value of the base line position) displayed on the setting information display portion W42 is increased. Thereby indicating that the baseline position is moving to the right. The set value of the baseline position, for example, a positive value indicates that the center is on the right side, and a negative value indicates that the center is on the left side.

Further, if the setting button B62 is touched with a finger or the like, the base line is set at the rightmost end, and the numerical value of the setting information display portion W42 and the illustration display a30 change in accordance therewith.

Further, if the software dial D13 is touched by a finger or the like to rotate counterclockwise or the dial 84 is rotated counterclockwise, the numerical value (the set value of the base line position) displayed on the setting information display portion W42 decreases, and the display a32 changed to the base line in the illustration display a30 is shifted to the left side together with the display a33 of the sewing pattern. Thereby indicating that the baseline position is moving to the left.

Further, if the setting button B61 is touched with a finger or the like, the base line is set at the leftmost end, and the numerical value of the setting information display portion W42 and the illustration display a30 are changed in accordance therewith.

The control device 90 controls the change of the display of the input screen G23 corresponding to the above input operation, and performs control of adjusting the sewing reference position according to the set value (W42) of the baseline position. However, when the cloth presser foot 3 is lifted, the adjustment of the sewing reference position is controlled after the cloth presser foot 3 is lowered.

[ conclusion, Effect and others ]

As described above, the control device 90 controls which of the touch operation type display input devices (81, 82) and the hardware operation unit (84) can perform an input operation for a predetermined operation item.

Therefore, the user can select any one of the operation units from the touch operation type display input devices (81, 82) and the hardware operation unit (84) to perform input operation as required, and operability is improved.

By applying a dial as a hardware operation unit (84) that generates a click operation feeling in accordance with a constant operation pitch, the user can easily recognize the operation amount by the touch feeling even if he/she performs a blind operation, and the operability is improved.

In addition, as a hardware operation part (84), a dial generating a clicking operation sound according to a certain operation pitch is applied, so that even if a user performs blind operation, the operation amount is easy to recognize through hearing, and the operability is improved. The operation sound may be electrically amplified and output through a speaker, and may be adjusted to a sound volume that can be easily heard.

On the other hand, when the touch operation type display input device (81, 82) is selected as the operation means, the area exclusive to the software operation unit is displayed to be large by utilizing the area and the display variability of the screen of the display unit 81, so that the user can easily perform a detailed input operation, and the operability is improved.

In the above embodiment, the predetermined operation items are set value adjustments of the sewing conditions, and the adjustments are 3 items of thread tension adjustment, sewing reference position adjustment, and adjustment of the feed amount of the object to be sewn. Therefore, the convenience of setting of the sewing device is improved. However, the scope of application of the present invention is not limited to these operation items.

The control device 90 changes the operation result display ((a10, W32), (a20, W51), or (a30, W42)) of the contact operation type display input device (81, 82) corresponding to the input operation in real time. Therefore, the user can easily recognize the current setting.

The control device 90 changes the operation result display in accordance with the predetermined operation item, similarly to both the input operation from the touch operation type display input devices (81, 82) and the input operation from the hardware operation unit (84). Since any of the operation units displays the real-time operation result in the same manner, the user can select any one of the operation units without any difference.

In the above embodiment, the case where the operation result display includes the numerical value display (W32, W51, or W42) that increases and decreases according to the operation amount and the display (a10, a20, or a30) that changes according to the operation amount by graphically representing the sewing conditions has been described. The user can perform accurate identification through numerical value display and visual identification through illustration display, and operability is improved.

In the above embodiment, the software reels (D11, D12, D13) are formed in an arc shape having a larger diameter than the hardware reel (84). The operability of the software dial (D11) is improved, and the space for disposing the hardware dial (84) is easily secured.
