[0011] Forms used to implement inventions

[0012] [Summary of the Implementation Forms of the Invention] The sewing apparatus of the present invention will now be described with reference to the accompanying drawings. FIG1 is a front view of the sewing machine 10 as the sewing apparatus, FIG2 is a left side view, and FIG3 is a functional block diagram showing the control system.

[0013] The sewing machine 10 includes: a needle up-and-down movement mechanism that uses a sewing machine motor 11 as a drive source to give the needle bar holding the needle 2 an up-and-down movement action; a lower feed mechanism that uses the power of the sewing machine motor 11 to feed the workpiece from below the needle plate via feed teeth; an upper feed mechanism that uses the power of the sewing machine motor 11 to feed the workpiece by contacting the upper feed member 4 from above; a rotary hook mechanism; a presser foot 3 that presses the workpiece on the needle plate from above; and a needle swing mechanism. The sewing machine 10 includes a needle bar that moves arbitrarily in a direction orthogonal to the fabric feed direction; a thread adjustment device that applies tension to the thread passing through the needle 2; a balance that pulls up the thread; a thread cutting device that cuts off the sewing ends of the upper and lower threads; a display input device 80 that displays various information about sewing and serves as a display input unit for accepting various settings; a control device 90 that controls the various components of the sewing machine 10; and a sewing machine frame 20 that houses or supports the various components of the sewing machine 10.

[0014] Furthermore, in the following explanation, the horizontal direction parallel to the direction in which the lower feed mechanism moves the workpiece is defined as the X-axis direction, and the downstream side of the workpiece's feed direction is defined as "forward," and the upstream side of the feed direction is defined as "rear." Also, the direction horizontal and orthogonal to the X-axis direction is defined as the Y-axis direction, with the left side defined as "left" and the right side as "right" facing forward. Furthermore, the direction orthogonal to both the X-axis and Y-axis directions is defined as the Z-axis direction, with one side defined as "up" and the other side as "down."

[0015] The sewing machine frame 20 includes: a sewing machine base 21 extending along the Y-axis; an upright body 22 erected from the right end of the sewing machine base 21; and a sewing machine arm 23 extending to the left from the upper end of the upright body 22 along the Y-axis. The needle bar of the needle 2, the presser foot 3, and the upper feed member 4 are supported at the lower left end of the sewing machine arm 23.

[0016] A rectangular display screen of a display input device 80 is disposed on the front surface of the upright fuselage 22. The front surface of the upright fuselage 22 and the display screen of the display input device 80, which is flush with the front surface, are composed of inclined surfaces that tilt the upper and left sides of the XZ plane slightly backward. By tilting as described above, the display screen of the input device 80 becomes easier to view for the operator of the sewing machine who is working from behind facing the needle drop position of the sewing machine 10.

[0017] The sewing machine base 21 has an upper surface that is a smooth surface along the XY plane, and the needle plate (not shown) is arranged flush with the upper surface of the sewing machine base 21 at the needle drop position of the needle 2.

[0018] Since the needle up-and-down movement mechanism is the same as the conventional mechanism, detailed description is omitted. The needle up-and-down movement mechanism can use the sewing machine motor 11 built into the sewing machine as the drive source, and use a crank mechanism to move the needle bar up and down.

[0019] Since the needle swing mechanism is the same as conventional mechanisms, detailed descriptions are omitted. The needle swing mechanism includes: a support frame that supports the needle bar so that it can move up and down; and a needle swing motor 15 that moves the front end of the needle bar arbitrarily along the Y-axis direction through the support frame.

[0020] Since the rotary hook mechanism is the same as the conventional mechanism, detailed description is omitted. The rotary hook mechanism has a shuttle that is powered by the sewing machine motor 11 and rotates on the underside of the needle plate. It catches the loop of the upper thread from the descending needle 2 and winds the lower thread to form a stitch on the workpiece. The balance is powered by the sewing machine motor 11 and moves up and down in the same cycle as the needle. The balance is equipped with an upper thread facing the needle, and when the shuttle has upper and lower threads forming a needle, the upper thread is pulled up to secure the needle.

[0021] Since the lower feed mechanism is the same as conventional mechanisms, detailed descriptions are omitted. The lower feed mechanism has feed teeth that allow the tooth tips to emerge from the opening of the needle plate, and extracts and assigns the reciprocating motion in the X-axis direction and the reciprocating motion in the Z-axis direction from the sewing machine motor 11 to the feed teeth. This causes the feed teeth to perform an elliptical motion around the Y-axis along the X-axis direction. Then, as the feed teeth pass through the upper part of the elliptical motion trajectory, the tooth tips protrude upwards from the opening of the needle plate and move forward, thus feeding the workpiece on the needle plate forward. Furthermore, the lower feed mechanism is equipped with a lower feed adjustment motor 12, which adjusts the travel width of the reciprocating motion in the X-axis direction transmitted from the sewing machine motor 11, thereby arbitrarily adjusting the amount of feed movement of the sewn workpiece formed by the feed teeth.

[0022] Since the upward feed mechanism is the same as conventional mechanisms, detailed descriptions are omitted. The upward feed mechanism has an upper feed member that feeds the workpiece from above the needle plate, abutting against it at the needle drop position. The reciprocating motion in the X-axis and Z-axis directions is extracted from the sewing machine motor 11 and assigned to the upper feed member. This causes the upper feed member to perform an elliptical motion about the Y-axis along the X-axis. Then, as the upper feed member passes the lower part of the elliptical motion trajectory, its front end moves forward along the upper surface of the needle plate, thus feeding the workpiece on the needle plate forward. Furthermore, the upper feed mechanism is equipped with an upper feed adjustment motor 13, which adjusts the travel width of the reciprocating motion in the X-axis direction transmitted from the sewing machine motor 11, thereby arbitrarily adjusting the amount of feed movement of the sewn workpiece formed by the feed teeth. Furthermore, the feed mechanism can be manually switched between a retracted position (no feed) and a feed position (feed), allowing selection of whether or not the feed mechanism is being executed. Alternatively, it can be configured as follows: a sensor is installed to detect whether the feed mechanism is in either the retracted or feed position, and its detection signal is input to the control device 90.

[0023] 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 installed at the lower end of the presser foot bar, which is suspended and supported by the lower left end of the sewing machine arm 23. The presser foot bar is given spring pressure inside the sewing machine arm 23, and can push the presser foot 3 towards the needle plate to apply pressure to the workpiece. The presser foot 3 comes in several types, and the appropriate presser foot 3 can be changed according to the type of sewing. Furthermore, the presser foot lever can be used to retract the presser foot 3 to the upper position via a manual lever (not shown) or a pressing motor 14. In addition, the pressing motor 14 can adjust the pressing pressure of the presser foot arbitrarily.

[0024] Because the wire adjustment device is the same as conventional mechanisms, detailed descriptions are omitted. The wire adjustment device, which is not shown in the diagram, clamps the upper wire midway through its path and applies tension to the upper wire through clamping pressure. The clamping pressure can be adjusted via the wire tension adjusting solenoid 16, thereby allowing arbitrary wire tension to be applied to the upper wire.

[0025] Since the thread-cutting device is the same as conventional mechanisms, detailed descriptions are omitted. The thread-cutting device has a cutter that operates between the needle plate and the rotary hook mechanism, and cuts both the upper and lower threads. The thread-cutting device has a thread-cutting solenoid 17 for actuating the cutter.

[0026] The display input device 80 includes: a display unit 81 disposed on the front surface of the vertical body part 22 of the sewing machine frame 20; a touch panel 82 disposed overlapping the front of the display unit 81; and three dials 83, 84, and 85 arranged approximately in the Y-axis direction on the lower side of the display unit 81. The display unit 81 is composed of a liquid crystal display or an organic EL (electroluminescence) display, and the display screen G1 described later is displayed through display control performed by the control device 90. The touch panel 82 functions as an input detection unit that detects the contact input position formed by the sewing machine operator and detects the input operation on the input screen G1. Each of the three turntables 83, 84, and 85 has a built-in encoder 831, 841, and 851, and the rotational operation caused by the operator is input to the control device 90 through the encoder 831, 841, and 851.

[0027] [Sewing machine control system] Next, based on Figure 3, the configuration of the control system of the sewing machine 10 will be explained. The control device 90 of the sewing machine 10 includes: a ROM 92, which stores various programs for performing various controls and processes described later, as well as various setting data such as sewing pattern data for performing various sewing; a CPU 91, which executes various programs stored in the ROM 92; a RAM 93, which becomes the working area when executing various programs; and an input / output interface 94 and an output interface 95, which are connected to the CPU 91, ROM 92 and RAM 93 through a bus.

[0028] The output interface 95 is connected to the sewing machine motor 11, the down feed adjustment motor 12, the up feed adjustment motor 13, the press motor 14, the needle swing motor 15, the thread adjustment solenoid 16, and the tweezers solenoid 17 via drive circuits 11a, 12a, 13a, 14a, 15a, 16a, and 17a. The CPU 91 can control these actions. The input / output interface 94 is connected to the components of the display input device 80 and the power switch 96.

[0029] The sewing machine 10 can control the forward and backward feed movement formed by the lower feed adjustment motor 12 and the left and right needle swing movement formed by the needle swing motor 15 through the control device 90, so as to put the needle on the workpiece at any position in the XY plane. The sewing pattern data consists of data representing multiple needle positions in the XY plane determined by the sewing pattern. The control device 90 can read the sewing pattern data and control the lower feed adjustment motor 12 and the needle swing motor 15 to perform sewing of the corresponding stitches for the sewing pattern.

[0030] [Display control of display input device] The display control of the display input device 80 performed by the control device 90 described above will be explained. The display control and input processing of the display input device 80 described below can all be performed by the CPU 91 of the control device 90 executing the program in the ROM 92.

[0031] Figure 4 is an explanatory diagram of 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 the plurality of display areas of the input screen G1 using virtual lines. In the explanatory diagrams showing these display examples and the other display examples described later, the top, bottom, left, and right directions on the paper are roughly the same as the top, bottom, left, and right directions on the sewing machine 10.

[0032] As shown in the figure, the input screen G1 is a long rectangle in the vertical direction and is divided into: a first area R1 that extends to the full width of the upper part of the screen, a second area R2 that extends to the full width of the screen below the first area R1, third to fifth areas R3 to R5 located below the second area R2, and a sixth area R6 that extends to the full width of the screen below the lower part of the screen. The third to fifth regions, R3 to R5, are formed by dividing the area between the second region R2 and the sixth region R6 into three rectangular regions that are longer at the top and bottom, with the third region R3 on the left, the fourth region R4 in the middle, and the fifth region R5 on the right. Although regions R3 to R5 in the example of Figure 5 are divided into three equal parts in the left and right direction, this is not a limitation, and the ratio of each region can be increased or decreased. For example, the left and right width of the central fourth region R4 can be changed within 1 / 4 to 1 / 2 of the overall width, and the left and right widths of the third region R3 and the fifth region R5 on both sides can be made equal.

[0033] In the first area R1, from left to right, there are a support button B11, a setting button B12, a sewing button B13, a history button B14, and a portal button B15, which are composed of string displays for switching between various input screens. These individual buttons B11 to B15 can be input via touch operation at their respective positions. Furthermore, the buttons B11 to B15 can be scrolled around by sliding left or right across the first area R1.

[0034] The support button B11 is used to switch the display to the support screen for displaying the operation manual of the sewing machine 10, etc. The setting button B12 is used to switch the display to a setting screen for setting the surrounding environment of the sewing machine 10, such as the brightness of the work light (not shown) and the volume of the speaker (not shown). The sewing button B13 is used to switch the display to the input screen G1 shown in Figure 4. This input screen G1 allows for various settings related to sewing. The History button B14 is used to switch the display to a history screen (not shown). The history screen is an input screen used to recall sewing pattern data and recorded settings related to the sewing process for multiple previously sewn patterns. The portal button B15 is used to switch the browser screen to the portal for connecting to the sewing machine 10 via a network line.

[0035] In the second area R2, from left to right, there are a candidate presser foot display frame W21 consisting of a pattern and text display, a sewing pattern selection button B21 for switching between various display screens, a sewing pattern setting button B22, and a cycle selection button B23.

[0036] The candidate presser foot display box W21 will show the types of presser feet 5 that are suitable for the currently selected sewing pattern. For example, in the example of Figure 4, pattern information and text information indicating the following are displayed: Presser feet A and B are suitable for the selected sewing pattern.

[0037] The pattern selection button B21 has a roughly rectangular contact area. Touching within this area will display a pattern selection screen. The control device 90 has multiple types of sewing patterns registered, each with a pattern number. After selecting a pattern number on the selection screen, the selected pattern number will be displayed within the roughly rectangular contact area of ​​the selection button B21.

[0038] The setting button B22 for the sewing pattern has a circular contact area, and an icon indicating that it is a setting button is displayed on its inner side. If you touch this contact area of ​​the setting button B22, the display will switch to the predetermined setting screen. This settings screen allows you to configure sewing patterns other than those set via buttons B31-B53 (described later). For example, you can edit sewing patterns by flipping them vertically or horizontally.

[0039] The cycle selection button B23 has a circular contact area, and an icon indicating that it is a cycle selection button is displayed inside its inner side. Touching the cycle selection button B23 within its contact area allows you to select whether to perform a single stitch or a continuous stitch. A single stitch involves sewing one portion of the pattern, while a continuous stitch involves repeating the stitch. The display control for this cycle selection button B23 is as follows: when single stitch is selected, the number "1" will be displayed inside the icon; when repeated stitch is selected, the number inside the icon will disappear.

[0040] In the third area R3 and the fifth area R5, three buttons are arranged vertically and vertically respectively. These buttons are used as operating parts for setting 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 zone R5, the following buttons are arranged in order from top to bottom: top feed setting button B51, pressure foot rise setting button B52, and tangent setting button B53. These various setting buttons B31, B32, B33, B51, B52, and B53 are designed with circular contact areas, and icons representing the content input from each setting button are displayed on their inner sides as content display sections. Furthermore, each of the various setting buttons B31, B32, B33, B51, B52, and B53 has a setting information display unit W31, W32, W33, W51, W52, and W53 arranged on its lower outer side. This unit displays the content input from each setting button and its setting value or setting status in text format.

[0041] The sewing start setting button B31 is used to select whether to perform a stop stitch at the beginning of the sewing process and the type of stop stitch. For example, by repeatedly touching the sewing start setting button B31 within its contact area, you can switch back to the settings for needle stitch, knotted stitch, or no stop stitch.

[0042] The tension setting button B32 is used to arbitrarily set the tension of the wire adjusting device formed by the wire adjusting solenoid 16. Touching the tension setting button B32 within its contact range will display the tension input screen, allowing the tension to be set via input operations on the screen or by rotating the dial 84.

[0043] The sewing end processing setting button B33 is used to select whether to perform a stop stitch at the end of the sewing and the type of stop stitch. For example, by repeatedly touching the contact area of ​​the sewing end processing setting button B33, you can switch back to the settings of needle stitch, knotted stitch, and no stop stitch.

[0044] The feed setting button B51 is used to set whether feed is performed by the feed unit 4 and the feed amount (the difference between the feed amount and the feed amount performed by the feed teeth). Touching the feed setting button B51 within its contact area will toggle the setting for feed performance. Furthermore, when feed is set to be performed, a feed amount input screen can be displayed, and the feed amount can be set by inputting to the screen or by rotating the dial 84.

[0045] The presser foot rise setting button B52 is used to set whether the presser foot 3 is automatically raised to release the sewn material when the sewing pattern is finished. By touching the presser foot rise setting button B52 within its contact range, you can toggle whether the automatic rise of the presser foot 3 is enabled or disabled.

[0046] The thread cutting setting button B53 is used to set whether the thread cutting device automatically performs the cutting at the end of the sewing pattern. By touching the thread cutting setting button B53 within its contact area, you can toggle the setting for whether automatic thread cutting is performed.

[0047] In the fourth area R4, arranged from top to bottom are a pattern image display frame W41 that displays the image of the currently selected sewing pattern, and a baseline position setting button B42 that serves as the operation unit.

[0048] A sewing pattern image composed of the currently selected sewing pattern can be displayed in the pattern image display box W41. This sewing pattern image is a dynamic image linked to the sewing action, and the current left-right needle position can be displayed at the top of the image. Furthermore, the stitches that will be formed at the next needle position can be displayed below the current needle position. This sewing pattern image is composed of a dynamic image of stitches moving upwards by one stitch for each stitch. Furthermore, the shape of this sewing pattern image will change according to the set values ​​of stitch length and stitch width described later.

[0049] The baseline position setting button B42 has a circular contact area, and an icon representing the content input from the baseline position setting button B42 is displayed on its inner side as a content display area. The baseline is the reference line for the sewing pattern along the fabric feed direction, and the amount of needle movement at each needle drop position of the sewing pattern is determined based on the baseline. If you touch the baseline position setting button B42 within its contact range, the baseline position input screen will be displayed. You can set the baseline position by inputting on the screen or by rotating the dial 84. A setting information display section W42 is arranged on the lower outer side of the baseline position setting button B42, which is a content display section that displays the content input from the button and its setting value in text.

[0050] In the sixth area R6, arranged from left to right are: a pressing pressure display unit W61, which displays the set value of the pressing pressure formed by the presser foot 3; a stitch width display unit W62, which displays the set value of the left and right width of the stitches of the sewing pattern; and a stitch length display unit W63, which displays the set value of the interval (sewing distance) of the fabric feed direction of each stitch.

[0051] The pressure display unit W61, the pin width display unit W62, and the pin length display unit W63 are respectively positioned on the top side of the turntables 83, 84, and 85. The pressing pressure is set based on the input rotation amount of the turntable 83 detected by the encoder 831, and the input pressing pressure setting value is displayed on the pressing pressure display unit W61. The pin width is set based on the input rotation amount of the turntable 84 detected by the encoder 841, and the input pin width setting value is displayed on the pin width display unit W62. The pin length is set based on the input rotation amount of the turntable 85 detected by the encoder 851, and the input pin length setting value is displayed on the pin length display unit W63.

[0052] As shown in Figure 6, the first region R1, the second region R2, and the sixth region R6 can be divided into three by the virtual extension line, i.e., the vertical virtual line L1 (a dashed line in Figure 6), which is the boundary of the third region R3, the fourth region R4, and the fifth region R5 that have been divided in the left and right directions. The above-mentioned display configurations, namely B11~B15, B21~23, W21, and W61~W63, are arranged in the divided regions.

[0053] In the first area R1, as described above, the support button B11, setting button B12, sewing button B13, history button B14, and website button B15, displayed as strings, are arranged sequentially from left to right. The sewing button B13 is located at the center position (in the left-right direction) of the area divided by the vertical virtual line L1, corresponding to the fourth area R4. The support button B11 and setting button B12 are located at the left position (in the left-right direction) of the area divided by the vertical virtual line L1, corresponding to the third area R3. The history button B14 and website button B15 are located at the right position (in the left-right direction) of the area divided by the vertical virtual line L1, corresponding to the fifth area R5.

[0054] When the first area R1 is slid left or right, causing the positions of buttons B11 to B15 to scroll, the position will be, for example, any one of B11 to B15. Alternatively, it can be displayed as follows: the position corresponding to the fourth area R4, divided by the vertical virtual line L1 (the center position in the left-right direction), with other components equally distributed on the third area R3 side and the fifth area R5 side, divided by the vertical virtual line L1.

[0055] In the second region R2, a selection button B21 is arranged at the position (center position in the left-right direction) divided by the vertical virtual line L1 corresponding to the fourth region R4. A candidate presser foot display frame W21 is arranged at the position (left position in the left-right direction) divided by the vertical virtual line L1 corresponding to the third region R3. A setting button B22 and a cycle selection button B23 are arranged at the position (right position in the left-right direction) divided by the vertical virtual line L1 corresponding to the fifth region R5.

[0056] In the sixth region R6, a pin width display unit W62 is arranged at the position (center position in the left-right direction) divided by the vertical virtual line L1 corresponding to the fourth region R4; a pressing pressure display unit W61 is arranged at the position (left position in the left-right direction) divided by the vertical virtual line L1 corresponding to the third region R3; and a pin length display unit W63 is arranged at the position (right position in the left-right direction) divided by the vertical virtual line L1 corresponding to the fifth region R5.

[0057] Furthermore, turntables 83-85 are also arranged by the vertical virtual line L1. Turntable 84 is arranged at the position divided by the vertical virtual line L1 corresponding to the fourth region R4 (the center position in the left-right direction), turntable 83 is arranged at the position divided by the vertical virtual line L1 corresponding to the third region R3 (the left position in the left-right direction), and turntable 85 is arranged at the position divided by the vertical virtual line L1 corresponding to the fifth region R5 (the right position in the left-right direction).

[0058] [Input screen display control] Next, the characteristic display control of the input screen G1 performed by the control device 90 will be explained with reference to Figures 4 to 7. Figure 7 is an explanatory diagram showing an example of the display of the input screen G1 after an input operation has been performed on a specific button.

[0059] The input screen G1 shown in Figure 4 above is the input screen G1 when the data related to the setting of the sewing pattern selected by the selection button B21 is in the initial setting state, that is, the default data state and the setting has not been changed. In this case, the control device 90 will perform the following display control.

[0060] The input screen G1 is displayed in the entire display area of ​​the display unit 81, and the background of the input screen G1 is displayed in a dark (e.g., black) manner. In addition, the stitched pattern image displayed in the pattern image display frame W41 on the input screen G1 is displayed in a light color (such as white) that is brighter than the background. Furthermore, the graphic and text information of the presser foot 5 in the candidate presser foot display frame W21, the icons in each button B21, B22, B23, B31, B32, B33, B42, B51, B52, B53, and the text information or setting values ​​of each display section W31, W32, W33, W42, W51, W52, W53, W61, W62, W63 are also displayed in a light color (such as white) that is brighter than the background. These can also be set to the same level of brightness as the stitched pattern image.

[0061] Furthermore, the text strings for the Support button B11, Setting button B12, Sewing button B13, History button B14, and Portal button B15 are displayed in a lighter color (e.g., gray) that is brighter than the background. Moreover, the text string for the currently selected button among these buttons B11~B15 ("Sewing button B13" in Figure 4) is displayed with a brightness higher than that of the unselected buttons among buttons B11~B15. The text display for the selected button can also be set to the same brightness level as the sewing pattern image.

[0062] Furthermore, within the contact area of ​​buttons B21, B22, B23, B31, B32, B33, B42, B51, B52, and B53, a lighter color (e.g., gray) with a brightness higher than the background will be displayed. Since the brightness of each button B21-B53 only needs to be visually identifiable by the sewing machine operator, it is acceptable not to increase the brightness difference between the background and the buttons. Also, increasing the brightness would make the inner icons difficult to read; therefore, the contact area is displayed with a brightness that is identifiable by the background but sufficiently lower than the inner icons.

[0063] In contrast, regarding the input screen G1 after a specific button has been pressed, the control device 90 will perform the following display control. Specifically, if any of buttons B22, B23, B31, B32, B33, B41, B51, B52, or B53 is used to modify preset data through input, the display within the contact area of ​​the modified button will become brighter. Furthermore, the display within the contact area of ​​the modified button will change to a blue-based color. Figure 7 illustrates the following situation: the preset data has been changed by inputting the sewing start setting button B31, the sewing end setting button B33, and the tangent setting button B53. This makes it immediately clear that the settings have been changed from the default data to the parameters specified by the button.

[0064] Furthermore, icons within the contact area of ​​buttons that have been changed to higher brightness will change from a light color (e.g., white) that is brighter than the background to a dark color (e.g., black). This makes icons easier to identify within the contact area of ​​the high-brightness button.

[0065] [Technical effects in the implementation of the invention] As described above, the control device 90 of the sewing machine 10 will perform the following display control: set the background of the input screen G1 to a dark color, set the sewing pattern image displayed in the pattern image display box W41 on the input screen G1 to a higher brightness than the background, and set each button B21~B53 that accepts input operations on the input screen G1 to a lighter color than the background. Because the background of the input screen G1 is dark, it is easier to see the displayed content compared to a brighter background. This reduces eye fatigue and eases the burden on operators, while improving visual recognition and operability to facilitate setup work and enhance overall workability.

[0066] Furthermore, because the sewing pattern image is displayed against a dark background and with a higher brightness than the background, the sewing pattern image can be clearly identified, allowing the sewing machine operator to correctly grasp the currently selected sewing pattern. Furthermore, since the sewing pattern image is a dynamic image that is linked to the sewing action of moving one stitch upwards with each stitch, the current sewing progress can be accurately grasped by clearly displaying it as described above. Furthermore, since the sewing pattern image is a dynamic image, even when viewing the input screen G1 to confirm the settings during sewing, and thus taking one's eyes off the actual needle 3, one can still grasp the sewing progress from the dynamic image, making it possible to effectively confirm the settings during sewing.

[0067] Furthermore, because buttons B21 to B53 are displayed in a lighter color than the background on the input screen G1, their locations are easily identified. Therefore, setting up operations using buttons B21 to B53 can be performed smoothly, thus improving workability. Furthermore, by setting the brightness of each button B21 to B53 to a lower level than the sewing pattern image, the clarity of the sewing pattern image can be avoided. Also, the buttons B21 to B53 located throughout the input screen G1 prevent the overall screen from becoming cluttered, making the displayed content easier to view and reducing the operator's workload, thus allowing for smooth setup operations and further improving workability.

[0068] Furthermore, the control device 90 will adjust the brightness of the contact area of ​​buttons B22 to B53 that have been input. This makes it clear whether any of the parameters set in the sewing pattern have been changed.

[0069] In particular, the control device 90 will change the display control of the contact area of ​​buttons B22 to B53 that have been input to a blue-based color. In this case, even if the sewing machine operator has a tendency to have low color vision, the changed parameters can be clearly understood. The decline in color perception primarily affects the recognition of red and green. Even with a reduced ability to distinguish red and green, colors with a blue undertone remain easily discernible. Therefore, even operators with diminished color perception can easily identify when a button has changed to a blue undertone, allowing more people to determine whether any parameter has been changed.

[0070] Furthermore, the control device 90 performs the following display control: displays icons inside buttons B22 to B53, and displays setting information display units W31 to W53 on the outside of buttons B31 to B53, and sets these to a brightness higher than the background. Therefore, the sewing machine operator can clearly identify the current settings of the sewing pattern and sew according to the desired settings.

[0071] Furthermore, the control device 90 displays a sewing pattern image in the fourth area R4 along the long side of the input screen G1. In addition, the display control is performed as follows: a plurality of buttons B31 to B33 and buttons B51 to B53 arranged along the long side of the input screen G1 are positioned in the third area R3 and the fifth area R5 on the left and right sides of the fourth area R4. This allows the sewing pattern image to be positioned near the center of the screen. Furthermore, when the long side of the sewing pattern image is displayed along the vertical direction, the direction in which the stitches formed by the sewing machine 10 are formed corresponds to the direction in which the stitches of the sewing pattern image extend, making it easier to grasp the sewing pattern. Furthermore, when the sewing pattern image is set as the aforementioned upward-moving dynamic image, the actual sewing pattern formation direction will correspond to the sewing pattern image direction, making it easier and more accurate to identify the stitch formation from the sewing pattern image.

[0072] In addition to the regional division of the first area R1 to the sixth area R6, the various display components, namely buttons B11 to B15, buttons B21 to B23, display unit W21, and display unit W61 to W63, are also divided and arranged by the vertical virtual line L1. The turntables 83 to 85 are also divided and arranged. Therefore, the arrangement of the displayed images is neat in any operation. The turntables 83 to 85, which are linked to the arrangement of the displayed images, are also consistent with the arrangement of the displayed images. For the operator, this provides a display effect with excellent visual recognition of the operation-related components.

[0073] [other] While the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above. The details shown in the above embodiments may be appropriately modified without departing from the spirit of the invention. For example, although the following situation is illustrated: when the preset data is changed by input operation for buttons B22 to B53, the control device 90 will perform display control to display the contact area of ​​the button with higher brightness; but it is not limited to this. For example, the control device 90 can also perform the following display control: at the time when an input operation is performed on buttons B22 to B53 (even if there is no change in the setting), the contact area of ​​the button will be displayed with higher brightness. In this way, the sewing machine operator can clearly see the button that is being input and its setting.
