[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 explanation, the horizontal direction parallel to the direction in which the lower feed mechanism feeds the workpiece is defined as the X-axis direction, with the downstream side of the workpiece feed direction being referred to as "front" and the upstream side as "rear". The horizontal direction perpendicular to the X-axis direction is defined as the Y-axis direction, with the left hand side being referred to as "left" and the right hand side being referred to as "right" when facing forward. The direction perpendicular to both the X-axis and Y-axis directions is defined as the Z-axis direction, with one side being referred to 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 backward a bit 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 visible easily 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 in the sewing machine as a driving source.

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

[0018] Since the bobbin mechanism is the same as a well-known mechanism, a detailed description thereof is omitted. The bobbin mechanism has a bobbin that rotates by obtaining power from the sewing machine motor 11 under the needle plate, captures the loop of the upper thread from the descending sewing needle 2, winds the lower thread, and forms a stitch on the sewing material. 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 stitching. 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 includes a display unit 81 provided on the front side of the vertical section 22 of the sewing machine frame 20, a touch panel 82 provided on top of 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 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 and other various setting data for performing various types of stitching, 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, and the sewing pattern selection button B21, sewing pattern setting button B22, and cycle selection button B23, which serve as operation parts for switching between various display screens, are arranged from left to right.

[0034] The presser foot candidate display frame W21 shows the types of presser feet 5 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 area, the display switches to the 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 roughly rectangular contact area of ​​the selection button B21.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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 is displayed, and the thread tension can be set by inputting on the screen or by rotating the dial 84.

[0041] 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.

[0042] 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 amount of the lower feed by the feed teeth and the upper feed amount). 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 the screen or by rotating the dial 84.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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. Furthermore, the shape of this sewing pattern image changes according to the settings for stitch length and stitch width, which will be described later.

[0047] 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 the 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.

[0048] 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.

[0049] 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 length setting value is numerically displayed on the stitch length display unit W63.

[0050] As shown in Figure 6, the first region R1, the second region R2, and the sixth region R6 are divided into three parts by a vertical virtual line L1 (dotted line in Figure 6), which is a virtual extension of the boundary between the third region R3, the fourth region R4, and the fifth region R5, which are divided in the left-right direction. The display configurations B11-B15, B21-23, W21, and W61-W63 described above are placed within the divided areas.

[0051] In the first area R1, as described above, the support button B11, settings button B12, sewing button B13, history button B14, and portal button B15, all consisting of text displays, are arranged in order from left to right. The sewing button B13 is located at the position (center in the left-right direction) divided by the vertical virtual line L1 corresponding to the fourth area R4, the support button B11 and settings button B12 are located at the position (left in the left-right direction) divided by the vertical virtual line L1 corresponding to the third area R3, and the history button B14 and portal button B15 are located at the position (right in the left-right direction) divided by the vertical virtual line L1 corresponding to the fifth area R5.

[0052] By swiping left or right across the first region R1, and scrolling through the positions of buttons B11 to B15, one of B11 to B15 will always be placed at a position (center position in the left-right direction) divided by the vertical virtual line L1 corresponding to the fourth region R4, while the other components may be displayed so as to be evenly distributed to the third region R3 and fifth region R5 sides, which are divided by the vertical virtual line L1.

[0053] In the second region R2, a selection button B21 is located at the position (center in the left-right direction) divided by the vertical virtual line L1 corresponding to the fourth region R4; a fabric presser foot candidate display frame W21 is located at the position (left in the left-right direction) divided by the vertical virtual line L1 corresponding to the third region R3; and a setting button B22 and a cycle selection button B23 are located at the position (right in the left-right direction) divided by the vertical virtual line L1 corresponding to the fifth region R5.

[0054] In the sixth region R6, a stitch width display unit W62 is located at the position (center in the left-right direction) divided by the vertical virtual line L1 corresponding to the fourth region R4, a presser foot pressure display unit W61 is located at the position (left in the left-right direction) divided by the vertical virtual line L1 corresponding to the third region R3, and a stitch length display unit W63 is located at the position (right in the left-right direction) divided by the vertical virtual line L1 corresponding to the fifth region R5.

[0055] Furthermore, dials 83 to 85 are also divided by a vertical imaginary line L1, with dial 84 positioned at the center position in the left-right direction (center position) of the vertical imaginary line L1 corresponding to the fourth region R4, dial 83 positioned at the left position in the left-right direction (left position) of the vertical imaginary line L1 corresponding to the third region R3, and dial 85 positioned at the right position in the left-right direction (right position) of the vertical imaginary line L1 corresponding to the fifth region R5.

[0056] [Display control of the input screen] Next, the characteristic display control performed by the control device 90 on the input screen G1 will be explained based on Figures 4 to 7. Figure 7 is an explanatory diagram showing an example of the display on the input screen G1 after an input operation has been performed on a specific button.

[0057] The input screen G1 in Figure 4, mentioned above, shows the input screen G1 when the recorded data for the sewing pattern settings selected by the selection button B21 remains in its initial state as default data and the settings have not been changed. In this case, the control device 90 performs the following display control.

[0058] The input screen G1 is displayed across the entire display range of the display unit 81, and the background of the input screen G1 is displayed in a dark color (for example, black). Furthermore, the sewing pattern image displayed in the pattern image display frame W41 on the input screen G1 is displayed in a light color (for example, white) with a higher brightness than the background. Furthermore, the design and text information for presser foot 5 within the presser foot candidate display frame W21, the icons within each button B21, B22, B23, B31, B32, B33, B42, B51, B52, B53, and the text information and setting values ​​for each display section W31, W32, W33, W42, W51, W52, W53, W61, W62, W63 are also displayed in a light color with a higher brightness than the background (for example, white). These may be set to the same brightness as the sewing pattern image.

[0059] Additionally, the text for the support button B11, settings button B12, sewing button B13, history button B14, and portal button B15 is displayed in a lighter color (for example, gray) with a higher brightness than the background. Furthermore, the text for the currently selected button (Sewing button B13 in Figure 4) is displayed with a brighter brightness than the unselected buttons within the same group. The text display for this selected button may be set to the same brightness level as the sewing pattern image.

[0060] Furthermore, the contact areas of each button B21, B22, B23, B31, B32, B33, B42, B51, B52, and B53 are displayed in a light color (e.g., gray) with a higher brightness than the background. Since the sewing machine operator only needs to be able to visually identify the location of each button B21-B53, the brightness difference between the background and the buttons does not need to be large. Also, increasing the brightness would make the inner icons difficult to distinguish, so the contact areas are displayed with a brightness that is distinguishable from the background but sufficiently lower than the inner icons.

[0061] In contrast, for the input screen G1 after an input operation has been performed on a specific button, the control device 90 performs the following display control. Specifically, if any of buttons B22, B23, B31, B32, B33, B41, B51, B52, or B53 are modified from their default data through input, the area within the contact range of the modified button will be displayed with a higher brightness. Furthermore, the area within the contact range of the modified button will be displayed with a predominantly blue color scheme. Figure 7 illustrates how changes are made to the default data through input operations on the sewing start setting button B31, sewing end setting button B33, and thread cutting setting button B53. This makes it immediately clear that the parameters assigned to the buttons have been changed from their default settings.

[0062] Additionally, the display is changed to a higher brightness, and icons within the button's contact area are changed from a light color (e.g., white) to a dark color (e.g., black) with a higher brightness than the background. This makes it easier to identify icons within the high-brightness button's contact area.

[0063] [Technical effects in embodiments of the invention] As described above, the control device 90 of the sewing machine 10 performs display control such as making the background of the input screen G1 a dark color overall, making the sewing pattern image displayed in the pattern image display frame W41 of the input screen G1 brighter than the background, and making each of the buttons B21 to B53 that accept input operations on the input screen G1 lighter than the background. Because the background of input screen G1 is generally dark, the displayed content is easier to see compared to when the entire input screen G1 is bright, reducing eye strain and the burden on the operator. This also improves visibility and operability, allowing for smoother setup work and improved overall work efficiency.

[0064] Furthermore, by displaying the sewing pattern image at a higher brightness than the background against a dark background, the sewing pattern image can be clearly recognized, allowing the sewing machine operator to accurately understand which sewing pattern is currently selected. Furthermore, since the sewing pattern image is a moving image that corresponds to the sewing action, with the stitches moving upward by one stitch each time a needle drops, it is displayed clearly as described above, making it possible to accurately grasp the current progress of the sewing. Furthermore, because the sewing pattern image is a moving image, even when checking the settings on the input screen G1 during sewing, the sewing progress can be understood from the moving image even when the eyes are taken off the actual sewing needle 3, making it possible to easily check the settings during sewing.

[0065] Furthermore, since buttons B21 to B53 are displayed in a lighter color than the background on the input screen G1, the location of each button B21 to B53 can be easily identified. This allows for smoother setup operations using buttons B21 to B53, thereby improving work efficiency. Furthermore, by setting the brightness of each button B21-B53 lower than that of the sewing pattern image, the clarity of the sewing pattern image is avoided. In addition, the placement of buttons B21-B53 throughout the input screen G1 prevents the entire screen from becoming cluttered, making the displayed content easier to see, reducing the burden on the operator, and allowing for smoother setting operations, thereby further improving work efficiency.

[0066] Furthermore, the control device 90 performs display control to increase the brightness of the contact area for buttons B22 to B53 that have been operated. This makes it possible to clearly understand which of the various parameters set in the sewing pattern have been changed.

[0067] In particular, the control device 90 performs display control to change the color scheme of the contact area of ​​buttons B22 to B53 that have been operated on to a predominantly blue color. In this case, even if the sewing machine operator has a tendency towards poor color vision, they will still be able to clearly understand the parameters whose settings have been changed. A decline in color vision perception primarily affects the ability to distinguish between red and green. However, even with this impairment, blue-based colors can still be easily recognized. Therefore, even operators with impaired color vision can easily recognize when a button changes to a blue-based color, allowing more people to understand which parameter has been modified.

[0068] Furthermore, the control device 90 displays icons inside buttons B22 to B53 and additionally displays setting information display units W31 to W53 outside buttons B31 to B53, and performs display control to set these to a brightness higher than the background. Therefore, the sewing machine operator can clearly recognize the current settings of the sewing pattern and perform sewing with the desired settings.

[0069] Furthermore, the control device 90 displays the sewing pattern image in the fourth region R4 along the longitudinal direction of the input screen G1. In addition, it performs display control to position the multiple buttons B31-B33 and buttons B51-B53, which are arranged along the longitudinal direction of the input screen G1, into the third region R3 and the fifth region R5 on both the left and right sides of the fourth region R4. This allows the sewing pattern image to be positioned near the center of the screen. Furthermore, when the sewing pattern image is displayed with its longitudinal direction aligned vertically, the direction in which the stitches are formed by the sewing machine 10 corresponds to the direction in which the stitches extend in the sewing pattern image, making it easy to understand the sewing pattern. Furthermore, if the sewing pattern image is made into a moving image that moves upward as described above, the orientation of the sewing pattern image will correspond to the orientation of the actual sewing pattern formation, making it possible to recognize the formation status of the seams more easily and accurately from the sewing pattern image.

[0070] In addition to dividing the display into areas R1 to R6, the vertical dashed line L1 separates and arranges each display component, buttons B11-B15, buttons B21-B23, display unit W21, and display units W61-W63. Dials 83-85 are also separated and arranged in this way. As a result, the layout of the display image is always neat, regardless of the operation, and the dials 83-85, which are linked to the layout of the display image, are consistent with the layout of the display image. This provides an excellent display effect, making the operation-related components highly visible to the operator.

[0071] [others] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above. Details shown in the above embodiments can be modified as appropriate without departing from the spirit of the invention. For example, the control device 90 may perform display control to display the contact area of ​​buttons B22 to B53 with higher brightness when a change is made to the default data due to an input operation, but this is not limited to this example. For example, the control device 90 may perform display control to display the contact area of ​​buttons B22 to B53 with higher brightness when an input operation is performed on those buttons (even if the settings are not changed). This makes it possible for the sewing machine operator to clearly understand which button is being used for input and its settings. [Explanation of symbols]
