[Modes for carrying out the invention]

[0010] [Outline of Embodiments of the Invention] The sewing device according to the present invention will be described below with reference to the drawings. Figure 1 is a front view of the sewing machine 10 as a sewing device, Figure 2 is a left side view, and Figure 3 is a functional block diagram showing the control system.

[0011] The sewing machine 10 includes a needle vertical movement mechanism that uses a sewing machine motor 11 as a drive source to give vertical movement to the needle bar that holds the sewing needle 2, a lower feed mechanism that uses the power of the sewing machine motor 11 to feed the workpiece from below the needle plate by feed dogs, an upper feed mechanism that uses the power of the sewing machine motor 11 to feed the workpiece from above by an upper feed 4 that contacts the workpiece from above, a bobbin mechanism, a presser foot 3 that presses down on the workpiece on the needle plate from above, a needle swing mechanism that moves the needle bar arbitrarily in a direction perpendicular to the fabric feed direction, a thread tension device that applies thread tension to the upper thread that passes through the sewing needle 2, a balance that pulls up the upper thread, a thread cutting device that cuts the end ends of the upper and lower threads, a display input device 80 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 houses or supports each component of the sewing machine 10.

[0012] In the following description, the horizontal direction parallel to the direction in which the lower feed mechanism feeds the sewing material is defined as the X-axis direction, the downstream side in the feeding direction of the sewing material is defined as "front", and the upstream side in the feeding direction is defined as "rear". Also, the horizontal direction orthogonal to the X-axis direction is defined as the Y-axis direction, the left side facing forward is defined as "left", and the right side is defined as "right". Further, the direction orthogonal to the X-axis direction and the Y-axis direction is defined as the Z-axis direction, one of which is defined as "up" and the other as "down".

[0013] The sewing machine frame 20 includes a sewing machine bed portion 21 extending along the Y-axis direction, a vertical cylinder portion 22 rising from the right end portion of the sewing machine bed portion 21, and a sewing machine arm portion 23 extending leftward along the Y-axis direction from the upper end portion of the vertical cylinder portion 22. The needle bar holding 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.

[0014] On the front side of the vertical cylinder portion 22, a rectangular display screen of the display input device 80 is arranged. The front surface of the vertical cylinder portion 22 and the display screen of the display input device 80 flush with the front surface are composed of an inclined surface that is inclined slightly rearward on the upper side and the left side of the X-Z plane. Due to the above inclination, the display screen of the display input device 80 is easily visible to the operator of the sewing machine who performs work facing the needle drop position of the sewing machine 10 from the rear.

[0015] 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 arranged flush with the upper surface of the sewing machine bed portion 21 at the needle drop position of the sewing needle 2.

[0016] Since the needle vertical movement mechanism is the same as a well-known mechanism, a detailed description thereof is omitted. The needle vertical movement mechanism can vertically move the needle bar by a crank mechanism using a sewing machine motor 11 built into the sewing machine as a drive source.

[0017] Since the needle swing mechanism is the same as a well-known mechanism, a detailed description thereof is omitted. The needle swing mechanism includes a support frame that supports the needle bar so as to be vertically movable, and a needle swing motor 15 that arbitrarily moves the tip of the needle bar along the Y-axis direction via the support frame.

[0018] The bobbin mechanism is the same as a well-known mechanism, so a detailed explanation will be omitted. The bobbin mechanism has a bobbin that rotates, powered by the sewing machine motor 11, located below the needle plate. It captures the loop of the upper thread from the descending sewing needle 2, entangles the lower thread, and forms a stitch on the workpiece. The balance beam receives power from the sewing machine motor 11 and moves up and down in the same cycle as the needle falls. The upper thread leading to the sewing needle is passed over the balance beam, and when the bobbin forms a stitch between the upper and lower threads, the balance beam pulls up the upper thread to fasten the stitch.

[0019] The lower feed mechanism is the same as a well-known mechanism, so a detailed explanation will be omitted. The lower feed mechanism has feed dogs that extend and retract their tips from an opening in the needle plate, and reciprocating motion in the X-axis direction and the Z-axis direction is taken from the sewing machine motor 11 and applied to the feed dogs. As a result, the feed dogs perform an elliptical motion around the Y-axis with their longitudinal direction aligned with the X-axis direction. Then, as the feed dogs pass over the trajectory of their elliptical motion, their tips protrude upward from the opening in the needle plate and move forward, feeding the workpiece on the needle plate forward. Furthermore, the lower feed mechanism is equipped with a lower 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, allowing the amount of material being fed by the feed dogs to be arbitrarily adjusted.

[0020] The upper feed mechanism is the same as a well-known mechanism, so a detailed explanation will be omitted. The upper feed mechanism has an upper feed that contacts the workpiece at the needle drop position from above the needle plate and performs a feeding operation. Reciprocating motion in the X-axis direction and reciprocating motion in the Z-axis direction are taken from the sewing machine motor 11 and applied to the upper feed. As a result, the upper feed performs an elliptical motion around the Y-axis with its longitudinal direction aligned with the X-axis direction. Then, as the upper feed passes the lower part of the trajectory of its elliptical motion, its tip moves forward along the upper surface of the needle plate, feeding the workpiece on the needle plate forward. Furthermore, the upper feed mechanism is equipped with 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, allowing the amount of material to be fed by the feed dogs to be adjusted as needed. Furthermore, the upward feed mechanism can be manually switched between a retracted position where feeding does not occur and a feed position where feeding does occur, allowing the user to select whether or not to perform the upward feed. A sensor may also be provided to detect whether the upward feed mechanism is in the retracted position or the feed position, and the detection signal may be input to the control device 90.

[0021] The presser foot 3 is located above the needle drop position on the needle plate and can press down on the workpiece from above. The presser foot 3 is attached to the lower end of a presser bar that is suspended from the lower left end of the sewing machine arm 23. The presser bar is subjected to spring pressure within the sewing machine arm 23, and the presser foot 3 is pressed toward the needle plate, applying pressing pressure to the workpiece. There are several types of presser foot 3, and you can replace it with the appropriate presser foot 3 depending on the type of sewing you are doing. Furthermore, the presser bar can be moved upward by a manual lever (not shown) or a presser motor 14. In addition, the presser motor 14 can adjust the pressing pressure of the presser foot as desired.

[0022] The thread tension device is the same as a well-known mechanism, so a detailed explanation is omitted. Although not shown in the diagram, the thread tension device clamps the upper thread in the middle of its path and applies tension to the upper thread by clamping pressure. The clamping pressure of the thread tension device can be adjusted by the thread tension solenoid 16, thereby allowing any desired thread tension to be applied to the upper thread.

[0023] The thread cutting device is the same as a well-known mechanism, so a detailed explanation will be omitted. The thread cutting device includes a blade that operates between the needle plate and the bobbin mechanism to cut the upper and lower threads. The thread cutting device is equipped with a thread cutting solenoid 17 for operating the blade.

[0024] The display input device 80 comprises a display unit 81 provided on the front side of the vertical section 22 of the sewing machine frame 20, a touch panel 82 superimposed on the front side of the display unit 81, and three dials 83, 84, and 85 provided just below the display unit 81, arranged in roughly the Y-axis direction. The portion of the display input device 80 consisting of the display unit 81 and the touch panel 82 corresponds to a contact-operated display input device in this embodiment, while the dials 83, 84, and 85 are hardware dials corresponding to a hardware operation unit. The display unit 81 consists of a liquid crystal display or an organic EL (Electro-Luminescence) and displays the input screen G1, which will be described later, through display control by the control device 90. The touch panel 82 functions as an input detection unit that detects the contact input position by the sewing machine operator and detects input operations on the input screen G1. The three dials 83, 84, and 85 each have built-in encoders 831, 841, and 851, respectively, and the amount of rotation performed by the operator is input to the control device 90 through the encoders 831, 841, and 851.

[0025] [Sewing machine control system] Next, the configuration of the control system of the sewing machine 10 will be explained based on Figure 3. The control device 90 of the sewing machine 10 includes a ROM 92 that stores various programs for various control and processing described later, sewing pattern data for various sewing operations, and other various setting data, a CPU 91 that executes the various programs in the ROM 92, a RAM 93 that serves as a work area when executing the various programs, and an input / output interface 94 and an output interface 95 connected to the CPU 91, ROM 92, and RAM 93 via a bus.

[0026] The output interface 95 is connected to the sewing machine motor 11, lower feed adjustment motor 12, upper feed adjustment motor 13, presser foot motor 14, needle swing motor 15, thread tension solenoid 16, and thread cutting solenoid 17 via drive circuits 11a, 12a, 13a, 14a, 15a, 16a, and 17a. The CPU 91 can control the operation of these components. The input / output interface 94 is connected to each component of the display input device 80 and to the power switch 96.

[0027] The sewing machine 10, using a control device 90, controls 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, making it possible to drop the needle at any position on the XY plane relative to the workpiece. Sewing pattern data consists of data indicating multiple needle drop positions within the XY plane, as defined by the sewing pattern. The control device 90 can read sewing pattern data and control the lower feed adjustment motor 12 and the needle swing motor 15 to perform sewing that forms stitches according to the sewing pattern.

[0028] [Display control of display input devices] The display control of the display input device 80 performed by the control device 90 described above will now be explained. All of the processing performed by the display control and input of the display input device 80 described below is carried out by the CPU 91 of the control device 90 executing a program in the ROM 92.

[0029] Figure 4 is an explanatory diagram showing an 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 dashed lines. In these explanatory diagrams showing example displays, as well as in the explanatory diagrams showing other example displays described later, the top, bottom, left, and right of the paper substantially coincide with the top, bottom, left, and right of the sewing machine 10.

[0030] As shown in the diagram, the input screen G1 is a vertically elongated rectangle and is divided into a first region R1 that extends across the entire width from left to right at the top of the screen, a second region R2 that extends across the entire width from left to right below it, third to fifth regions R3 to R5 located below that, and a sixth region R6 that extends across the entire width from left to right at the bottom of the screen. The third to fifth regions R3 to R5 are vertically elongated rectangular regions created by dividing the area between the second region R2 and the sixth region R6 into three horizontally. The left side is the third region R3, the middle is the fourth region R4, and the right side is the fifth region R5. In the example in Figure 5, the third to fifth regions R3 to R5 are divided into three equal parts horizontally, but this is not the only way, and the individual ratios can be increased or decreased. For example, the width of the central fourth region R4 can be changed within the range of 1 / 4 to 1 / 2 of the total width, and the widths of the third region R3 and the fifth region R5 on either side can be made equal.

[0031] In the first area R1, the following buttons are arranged from left to right in order: support button B11 (which displays text), settings button B12, sewing button B13, history button B14, and portal button B15, all of which are used to switch between various input screens. Each of these buttons B11-B15 can be accessed by touching its respective location. Additionally, swiping the first area R1 left or right will scroll the positions of each button B11-B15.

[0032] Support button B11 is used to switch the display to the support screen, which shows the operation manual for sewing machine 10, etc. The setting button B12 is used to switch the display to a settings screen for adjusting settings related to the surrounding environment of the sewing machine 10, such as the brightness of the work light (not shown) and the speaker volume (not shown). Sewing button B13 is a button used to switch the display to input screen G1 in Figure 4. This input screen G1 allows you to make various settings related to sewing. The history button B14 is used to switch the display to the history screen, which is not shown in the diagram. The history screen is an input screen for retrieving sewing pattern data and recorded data related to the settings used during sewing for multiple sewing patterns that have been sewn in the past. Portal button B15 is a button that switches the display to a browser screen for connecting to the Sewing Machine 10 portal site via the network connection.

[0033] 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, and the sewing pattern selection button B21, sewing pattern setting button B22, and cycle selection button B23, which serve as the operation section, are arranged from left to right.

[0034] The presser foot candidate display frame W21 shows the types of presser feet 3 that are suitable for the currently selected sewing pattern. For example, in the example in Figure 4, graphic and text information is displayed indicating that presser feet A and B are suitable for the selected sewing pattern.

[0035] The sewing pattern selection button B21 has a roughly rectangular contact area, and when touched within this contact area, the display switches to the sewing pattern selection screen G3 (Figure 6). Multiple types of sewing patterns are registered in the control device 90, and each sewing pattern is assigned a pattern number (identification number). When a pattern number is selected and confirmed on the selection screen G3, the selected pattern number (identification number) is displayed within the roughly rectangular contact area of ​​the selection button B21.

[0036] Details regarding the selection of sewing patterns are as follows: Figure 6 is an explanatory diagram showing an example of the display of the sewing pattern selection screen G3 shown on the display unit 81 of the display input device 80. The top of the selection screen G3 displays the genre names B71-B73. The bottom of the selection screen G3 displays the pattern number (identification number). The pattern number consists of three digits: hundreds digit A41, tens digit A42, and units digit A43. Furthermore, below pattern numbers A41-A43 in selection screen G3, lines A44 indicate that dial 83 corresponds to the operation of A41 in the hundreds digit, line A45 indicates that dial 84 corresponds to the operation of A42 in the tens digit, and line A46 indicates that dial 85 corresponds to the operation of A43 in the units digit. Additionally, the area between the genre names B71-B73 and pattern numbers A41-A43 on selection screen G3 displays the sewing pattern list page L3.

[0037] In Figure 6, the first 15 sewing pattern thumbnails B101- of the list page L3 for buttonhole stitching B72 are displayed in a 5x3 matrix. The thumbnails will be labeled B001 to B999, corresponding to pattern numbers 001 to 999 in order. There may be pattern numbers that do not have a sewing pattern assigned to them (missing numbers). In Figure 6, sewing pattern thumbnails B101-B105 are arranged in the upper row, sewing pattern thumbnails B106-B110 in the middle row, and sewing pattern thumbnails B111-B115 in the lower row. The lower part of sewing pattern thumbnails B111-B115 in the lower row, which overlap as the background for pattern numbers A41-A43, is displayed with a gradient that gradually darkens towards the bottom, increasing the contrast with pattern numbers A41-A43 and making them easier to read.

[0038] The list page L3 for buttonhole stitching B72 has more than 15 additional sewing patterns registered. By flicking (or swiping) vertically on the selection screen G3, you can display subsequent sewing pattern thumbnails after sewing pattern thumbnail B115, or return to the top of the page, allowing you to view the entire list page L3. Additionally, by swiping horizontally on the selection screen G3, you can display list pages for other genres (for example, swiping left from Figure 6 will display the list page for appliqué B73). Based on the above, all sewing patterns are available for viewing.

[0039] Each sewing pattern thumbnail B101- displays not only the pattern image but also the pattern number for that sewing pattern. A list of all sewing pattern images and pattern numbers is also provided in other media, for example, as shown in Figure 7. Figure 7 shows an example configuration in which the complete sewing pattern list 89 is arranged inside the top cover 88 of the sewing machine arm section 23. The top cover 88 is supported at its rear end by a hinge, and Figure 7 shows the top cover 88 in the open position. Each sewing pattern thumbnail B101- acts as a software key, allowing you to select and confirm a pattern by touching it with your finger or other object.

[0040] The selection method using pattern numbers is as follows: The hundreds digit A41 of the pattern number is a number that identifies each genre and each list page. For example, in Figure 6, the hundreds digit A41 is "1", which identifies list page L3 for buttonhole stitching B72, and this list page L3 is displayed on selection screen G3. By turning dial 83 to change the hundreds digit A41, a list page corresponding to the number in the hundreds digit A41 will be displayed on selection screen G3. The hundreds digit A41, the tens digit A42, and the units digit A43 form an identification number that identifies each individual sewing pattern. If we now turn dial 83 to set the hundreds digit A41 to "1", dial 84 to set the tens digit A42 to "0", and dial 85 to set the units digit A43 to "6", that is, if we set the identification number (A41-A43) to "106", then sewing pattern thumbnail B106 will be displayed as shown in Figure 6.

[0041] In this manner, the control device 90 switches and controls the sewing pattern displayed on the display unit 81 in response to input operations to the hardware operation units (83, 84, 85). Furthermore, the control device 90 displays the sewing pattern identification numbers (A41-A43) and the sewing pattern (B106) identified by the said identification numbers on the display unit 81 in response to input operations on the hardware operation units (83, 84, 85). Furthermore, in this embodiment, the control device 90 displays the sewing pattern identification numbers (A41-A43) on the display unit 81 in response to input operations on the hardware operation units (83, 84, 85), and also displays a list page (L3) that includes the sewing pattern (B106) identified by the said identification number and other sewing patterns. On list page L3 of buttonhole stitching B72, sewing patterns with identification numbers "101" through "122" are registered. For example, if you turn the dial 83-85 to set the identification number (A41-A43) to "112", sewing pattern thumbnails B111-B115, which include sewing pattern thumbnail B112, will be displayed in the middle section. For example, if you turn the dial 83-85 to set the identification number (A41-A43) to "118", sewing pattern thumbnails B116-B120 (not shown), which include sewing pattern thumbnail B118 (not shown), will be displayed in the middle section.

[0042] The control device 90 controls the above display. The control device 90 enlarges the portion of the list page (L3) containing the sewing pattern (B106) identified by the identification number (A41-A43), and controls the display so that other portions of the list page can be viewed by scrolling. When an identification number is entered by the hardware operation unit (83, 84, 85), the control device 90 places the sewing pattern identified by the identification number in a predetermined area on the screen. In this embodiment, the control device 90 sets the predetermined area to the vertical center (= middle section) of screen G3. Notwithstanding this embodiment, depending on the scrolling direction of the list page, the predetermined area may be the horizontal center of the screen (in the case of horizontal scrolling), or the vertical and horizontal center of the screen (in the case of vertical and horizontal scrolling).

[0043] However, this does not apply if the identification numbers of the sewing patterns included in the top row (B101-B105) and the last row (B121-122) of the list page are selected using dial 83-85. The top row (B101-B105) will be displayed in the upper row, and the last row (B121-122) will be displayed in the lower row. This is to display as many sewing patterns as possible on the screen without scrolling into the margins. Nevertheless, even for the sewing patterns included in the top row (B101-B105) and the last row (B121-122) of the list page, if selected using dial 83-85, they may be displayed in the middle row.

[0044] When a user touches the sewing pattern thumbnail B106 with their finger or the like, the sewing pattern to be applied to sewing is determined to be the sewing pattern thumbnail 106. In other words, the control device 90 determines the sewing pattern based on a screen touch on one of the sewing patterns (B106) in the list page (L3) detected by the input detection unit (touch panel 82). Once the sewing pattern is determined, the control device 90 returns to the input screen G1 and displays the pattern number of the determined sewing pattern on the selection button B21. Furthermore, if a missing number is selected using dial 83-85, the control device 90 will not perform any control over the display portion of the list page shown on the selection screen G3.

[0045] The sewing pattern setting button B22 has a circular contact area, and an icon indicating that it is a setting button is displayed inside this area. Touching the contact area of ​​setting button B22 switches the display to a predetermined setting screen. From this setting screen, you can make settings related to the sewing pattern other than the parameters set by buttons B31 to B53, which will be described later. For example, you can edit the sewing pattern, such as flipping it vertically or horizontally, from this setting screen.

[0046] The cycle selection button B23 has a circular contact area, and an icon indicating that it is a cycle selection button is displayed inside this area. Touching the contact area of ​​the cycle selection button B23 allows you to set whether to perform single-stroke sewing, which sews one sewing pattern at a time, or continuous sewing, which sews repeatedly. For this cycle selection button B23, the number "1" is displayed inside the icon when single-stroke sewing is selected, and the number inside the icon disappears when continuous sewing is selected.

[0047] In the third region R3 and the fifth region R5, there are three buttons arranged vertically in each region, which serve as operating buttons for setting predetermined settings for the sewing pattern. In the third area R3, the sewing start setting button B31, the thread tension setting button B32, and the sewing end setting button B33 are arranged in order from top to bottom. In the fifth area R5, the upper feed setting button B51, the presser foot lifting setting button B52, and the thread cutting setting button B53 are arranged in order from top to bottom. These various setting buttons B31, B32, B33, B51, B52, and B53 each have a circular contact area, and inside this area, icons are displayed as content indicators showing the input content for each setting button. Furthermore, at the lower outer edges of the various setting buttons B31, B32, B33, B51, B52, and B53, there are setting information display units W31, W32, W33, W51, W52, and W53, respectively, which display the content entered from each setting button and its setting value or setting status in text format.

[0048] The sewing start setting button B31 is a button that allows you to select whether or not to perform a backstitch at the beginning of the sewing process and the type of backstitch. For example, by repeatedly touching the contact area of ​​the sewing start setting button B31, you can switch between backstitch, knot stitch, and no backstitch setting.

[0049] The thread tension setting button B32 is a button for arbitrarily setting the thread tension of the thread tension device operated by the thread tension solenoid 16. When the user touches within the contact range of the thread tension setting button B32, a thread tension input screen (not shown) is displayed, and the thread tension can be set by inputting on this screen or by rotating the dial 84.

[0050] The sewing end processing setting button B33 is a button that allows you to select whether or not to perform a backstitch at the end of the sewing and the type of backstitch. For example, by repeatedly touching the contact area of ​​the sewing end processing setting button B33, you can switch between backstitch, knot stitch, and no backstitch.

[0051] The upper feed setting button B51 is used to set whether or not to perform an upper feed using the upper feed 4 and the amount of the upper feed (the difference between the upper feed amount and the lower feed amount by the feed teeth). Touching the upper feed setting button B51 within its contact range switches the setting between performing an upper feed and not performing one. When the upper feed is set to perform one, an input screen for the upper feed amount is displayed, and the upper feed amount can be set by inputting on this screen or by rotating the dial 84.

[0052] The presser foot lift setting button B52 is a button that sets whether or not to automatically raise the presser foot 3 and release the workpiece when sewing a sewing pattern is complete. Touching the contact area of ​​the presser foot lift setting button B52 switches the setting on or off whether or not to perform the automatic raising of the presser foot 3.

[0053] The thread cutting setting button B53 is used to set whether or not to automatically cut the thread using the thread cutting device when sewing a sewing pattern is complete. Touching the contact area of ​​the thread cutting setting button B53 switches the setting on or off for automatic thread cutting.

[0054] In the fourth area R4, the pattern image display frame W41, which displays the image of the currently selected sewing pattern, and the baseline position setting button B42, which serves as the control unit, are arranged from top to bottom.

[0055] The pattern image display frame W41 displays a sewing pattern image consisting of the design of the currently selected sewing pattern. 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 needle is currently dropping is displayed at the top of the image. Below the needle drop position, the stitch that will be formed at the needle drop position is displayed. This sewing pattern image is a moving image in which one stitch's worth of stitch moves upward each time a needle is dropped.

[0056] The baseline position setting button B42 has a circular contact area, and an icon is displayed inside this area as a content display section indicating the content to be entered from the baseline position setting button B42. The baseline is the reference line of the sewing pattern along the fabric feed direction, and the amount of needle swing at each needle drop position of the sewing pattern is determined based on this baseline. When the user touches the contact area of ​​the baseline position setting button B42, the baseline position input screen is displayed, and the baseline position can be set by inputting information on this screen or by rotating the dial 84. The lower outer side of the baseline position setting button B42 is a setting information display unit W42, which displays the content entered via the button and its setting value as text information.

[0057] In the sixth area R6, the following are arranged from left to right: a presser foot pressure display unit W61 that numerically displays the set value of the presser foot pressure by the presser foot 3; a stitch width display unit W62 that numerically displays the set value of the left-right width of the needle swing of the sewing pattern; and a stitch length display unit W63 that numerically displays the set value of the interval (sewing pitch) in the fabric feed direction for each stitch.

[0058] The presser foot pressure indicator W61, the stitch width indicator W62, and the stitch length indicator W63 are positioned directly above dials 83, 84, and 85, respectively. The clamping pressure is set based on the input rotation amount of the dial 83 detected by the encoder 831, and the input clamping pressure setting value is numerically displayed on the clamping pressure display unit 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 numerically displayed on the stitch width display unit 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 numerically displayed on the stitch width display unit W63.

[0059] [Summary, effects, and other information] As described above, the control device 90 switches and controls the sewing pattern displayed on the display unit 81 in response to input operations to the hardware operation units (83, 84, 85). Therefore, when the number of pages between the currently displayed page and the desired page is large, the cumbersome process of performing multiple flick or other touch operations on the screen can be avoided by rotating the dial, improving the usability of selecting sewing patterns. Compared to screen touch operations that involve sliding actions such as flicking and swiping the screen, operation using a hardware dial requires fewer steps and involves smaller movements, thus shortening the operation time. Regardless of the above embodiments, the same effects can be obtained even if only a hardware operation unit (83) that supports page turning operations is implemented. Therefore, it is not always necessary to adopt a pattern number specification method.

[0060] Furthermore, as described above, the control device 90 displays the sewing pattern identification numbers (A41-A43) on the display unit 81 in response to input operations to the hardware operation units (83, 84, 85), and also displays the sewing pattern (B106) identified by the said identification numbers. Therefore, if a user knows the identification number of a sewing pattern, they can directly access the desired sewing pattern on the screen by entering that identification number, improving the ease of selecting sewing patterns.

[0061] Furthermore, as described above, the control device 90 displays the sewing pattern identification numbers (A41-A43) on the display unit 81 in response to input operations on the hardware operation units (83, 84, 85), and also displays a list page (L3) that includes the sewing pattern (B106) identified by the said identification number and other sewing patterns. Sewing patterns are categorized and organized across multiple list pages, with similar sewing patterns arranged relatively close together on each page. Therefore, users can easily select a sewing pattern similar to a sewing pattern whose identification number they know, with fewer steps, improving the ease of use of sewing pattern selection.

[0062] Furthermore, as described above, the control device 90 enlarges the portion of the list page (L3) that contains the sewing pattern (B106) identified by the identification number (A41-A43), and controls it so that other parts of the list page can be displayed by scrolling. Therefore, even if the number of similar sewing patterns becomes enormous, they can be displayed clearly and easily by enlarging a portion of the list page, while at the same time, scrolling makes it easy to view every corner of the page, improving the usability of selecting sewing patterns.

[0063] Furthermore, as described above, the control device 90 places the sewing pattern identified by the input identification number in a predetermined area (the middle section in the above embodiment). Therefore, users can easily find the sewing pattern corresponding to the identification number they entered on the screen, improving the ease of selecting sewing patterns. By designating a predetermined area as the central area of ​​the screen in the vertical and / or horizontal direction, the sewing pattern corresponding to the identification number entered by the user can be displayed clearly on the screen, and similar sewing patterns before and after can also be displayed, improving the usability of selecting sewing patterns.

[0064] Furthermore, as described above, screen scrolling and sewing pattern selection can be performed by touching the screen, and the operability is good due to the linkage between the hardware operation unit (83, 84, 85) and the touch panel 82, improving the ease of selecting sewing patterns.

[0065] Furthermore, as described above, the hardware operation section includes dials 83, 84, and 85, each individually provided for a digit of the identification number, which allow for the modification of the numerical values ​​of the digits in the identification number. Therefore, dials for digits that do not change do not need to be operated, and with one dial, only 10 steps from 0 to 9 are required, reducing the amount of dial operation and improving the ease of selecting sewing patterns. Furthermore, since a dial is used as the hardware control, it offers better operability compared to using two keys (an up key and a down key) to increase or decrease the numbers, improving the ease of selecting sewing patterns. The above embodiment does not prevent the selection of a hardware operating unit other than a dial. For example, a hardware numeric keypad may be used to input pattern numbers.
