[Display Control of Input Screen]
Next, characteristic display control for the input screen G1 performed by the control apparatus 90 will be described with reference to
In the input screen G1 of
In this case, the control apparatus 90 performs the following display control.
The input screen G1 is displayed in the whole display range of the display unit 81, and a background of the input screen G1 is displayed with a dark color (for example, black) as a whole.
The sewing pattern image displayed in the pattern image display frame W41 of the input screen G1 is displayed with a light color (for example, white), the brightness of which is higher than that of the background.
The pattern information and character information of the presser foot 3 in the presser foot candidate display frame W21, the icons in the respective buttons B21, B22, B23, B31, B32, B33, B42, B51, B52, and B53, the character information and setting numerical values of the respective display units W31, W32, W33, W42, W51, W52, W53, W61, W62, and W63 are also displayed with a light color (for example, white), the brightness of which is higher than that of the background. The pattern information and character information thereof, the icons therein, and the character information and setting numerical values thereof may have the same brightness as that of the sewing pattern image.
The character string displays of the support button B11, the setting button B12, the sewing button B13, the history button B14, and the portal button B15 are also displayed with a light color (for example, gray), the brightness of which is higher than that of the background. The character string display of the currently selected button (“the sewing button B13” in
The character string display of the selected button may be set to the same brightness as that of the sewing pattern image.
The contact ranges of the respective buttons B21, B22, B23, B31, B32, B33, B42, B51, B52, and B53 are displayed with a light color (for example, gray), the brightness of which is higher than that of the background. With respect to each of the buttons B21 to B53, since an operator of the sewing machine only needs to visually recognize the location of each button, a difference in brightness between the background and the button may not be large. When the brightness of the button is increased, it becomes difficult to identify the icon inside the button, such that the contact range is displayed with brightness which is identifiable with the background and is sufficiently lower than that of the icon inside the button.
On the other hand, the control apparatus 90 performs the following display control on the input screen G1 after the input operation is performed on the specific button.
Specifically, when the input operation is performed on any one of the buttons B22, B23, B31, B32, B33, B41, B51, B52, and B53 and the default data thereof is changed, the contact range of the changed button is changed to be displayed with higher brightness. The contact range of the changed button is changed to be displayed with a color based on blue.
Accordingly, it can be recognized at a glance that a setting content is changed from the default data with respect to the parameter determined by the button.
The icon within the contact range of the button, the display of which is changed to higher brightness, is changed from the light color (for example, white), the brightness of which is higher than that of the background, to the dark color (for example, black). Accordingly, it is possible to easily identify the icon within the contact range of the button having the high brightness.
As described above, the control apparatus 90 of the sewing machine 10 performs the display control in which the background of the input screen G1 is set to the dark color as a whole, the sewing pattern image displayed in the pattern image display frame W41 of the input screen G1 is set to brightness higher than that of the background, and the respective buttons B21 to B53 that receive the input operations on the input screen G1 are set to the color lighter than that of the background.
Since the background of the input screen G1 is dark as a whole in this manner, it is easier to see a display content than a case where the input screen G1 is bright as a whole, such that eye fatigue is reduced, a burden on the operator is reduced, and visibility and operability are improved, thereby making it possible to smoothly perform setting work and improve workability.
Since the sewing pattern image is displayed with brightness higher than that of the background in a state where the dark color is used for the background, the sewing pattern image can be clearly recognized, and the operator of the sewing machine can accurately grasp the currently selected sewing pattern.
Since the sewing pattern image is the moving image that is linked to the sewing operation, in which the seam for one stitch moves upward every time one stitch point is performed, it is possible to accurately grasp a progress state of the current sewing by performing clear display as described above.
The sewing pattern image is such a moving image, such that even when the setting content is confirmed by looking at the input screen G1 during the sewing, it is possible to grasp the progress state of the sewing from the moving image even in a state where the user takes the eyes off the actual sewing needle 2, and the setting content during the sewing can be satisfactorily confirmed.
Since each of the buttons B21 to B53 is displayed with the color lighter than that of the background in the input screen G1, the location of each of the buttons B21 to B53 can be easily grasped. Therefore, the setting work using the buttons B21 to B53 can be smoothly performed, such that the workability can be improved.
When the brightness of each of the buttons B21 to B53 is lower than that of the sewing pattern image, it is possible to avoid damaging the sharpness of the sewing pattern image. The buttons B21 to B53 disposed in the respective locations on the input screen G1 prevent the whole screen from becoming complicated, such that the display content is easy to be seen, the burden on the operator can be reduced, the setting work can be smoothly performed, and the workability can be further improved.
The control apparatus 90 performs the display control for increasing the brightness of the contact range of the buttons B22 to B53 on which the input operation is performed.
Accordingly, it is possible to clearly grasp which of the various parameters set in the sewing pattern is changed.
Particularly, the control apparatus 90 performs the display control for changing the color of the contact range of the buttons B22 to B53, on which the input operation is performed, to the color based on blue.
In this case, even when the sewing machine operator tends to have low color vision recognition ability, it is possible to clearly grasp the parameter whose setting is changed.
Deterioration in the color vision recognition ability is likely to occur mainly with respect to distinguishment between red and green. As described above, even when the deterioration in distinguishment ability between red and green occurs, the color based on blue can be easily recognized. Therefore, even the operator whose color vision recognition ability deteriorates can easily recognize that the color of the button is changed to the color based on blue, such that more people can grasp which of the parameters is changed.
The control apparatus 90 displays the icon inside the buttons B22 to B53, additionally displays the setting information display units W31 to W53 on the outside of the buttons B31 to B53, and performs the display control for allowing the buttons B22 to B53 and the setting information display units W31 to W53 to have brightness higher than that of the background.
Therefore, the sewing machine operator can clearly recognize the current setting content of the sewing pattern, thereby making it possible to perform sewing with the desired setting content.
The control apparatus 90 displays the sewing pattern image in the fourth area R4 along the longitudinal direction of the input screen G1. The control apparatus 90 further perform the display control in which a plurality of buttons B31 to B33 and buttons B51 to B53 disposed along the longitudinal direction of the input screen G1 are disposed in the third area R3 and the fifth area R5 on both the left and right sides of the fourth area R4.
Accordingly, it is possible to dispose the sewing pattern image near the center of the screen. When the longitudinal direction of the sewing pattern image is displayed along a vertical direction, a seam forming direction by the sewing machine 10 and a seam extending direction of the sewing pattern image correspond to each other, such that the sewing pattern can be easily grasped.
When the sewing pattern image is set to the moving image that moves upward as described above, a direction in which the actual sewing pattern is formed and the sewing pattern image correspond to each other, such that it becomes possible to more easily and accurately recognize a formation state of the seam from the sewing pattern image.
In addition to the area division of the first area R1 to the sixth area R6, the buttons B11 to B15, the buttons B21 to B23, the display unit W21, and the display units W61 to W63, which are respective display configurations, are divided and disposed by the vertical virtual line L1, and the dials 83 to 85 are also divided and disposed, such that a layout of a display image is arranged in order regardless of any operation, and the dials 83 to 85 linked to the layout of the display image are also consistent with the layout of the display image, thereby achieving a display effect that visibility of an operation-related configuration is significantly good for the operator.
While the embodiments of the present invention are described above, the present invention is not limited thereto. The details shown in the embodiments can be appropriately modified without departing from the spirit of the invention.
For example, while the embodiments describe a case where the control apparatus 90 performs the display control in which when the input operation is performed on the buttons B22 to B53 and the default data thereof is changed, the contact range of the button is displayed with higher brightness, the present invention is not limited thereto.
For example, the control apparatus 90 may perform display control in which when the input operation is performed on the buttons B22 to B53 (even when the setting content is not changed), the contact range of the button is displayed with higher brightness. Accordingly, the operator of the sewing machine can clearly grasp a button on which the input operation is performed and a setting content thereof.
