[0004] [Patent Document 1] JP 2006-156809 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when the dicing device is in operation and the operator wants to check the processing conditions or information of the wafer, if the operator touches a desired button, such as the "processing conditions confirmation button" or the "wafer information button" from among the multiple buttons displayed on the menu screen of the touch panel, but accidentally presses another button, such as the "cutting blade replacement button," the operation of the dicing device will be interrupted, requiring recovery work and causing a decrease in productivity. This type of problem is not limited to dicing devices, but can occur in other devices equipped with touch panels, such as laser processing devices and grinding devices.

[0006] The present invention has been made in consideration of the above-mentioned facts, and its main technical objective is to provide a touch panel that can solve the problem of reduced productivity of a device in which the touch panel is installed due to pressing the wrong button on the touch panel. [Means for solving the problem]

[0007] In order to solve the above-mentioned main technical problem, according to the present invention, there is provided a touch panel that displays an image on which a plurality of function buttons are arranged, and the plurality of function buttons are provided with a function that is activated by pressing the function buttons for a predetermined period of time. By The function is activated It is possible a long press button for pressing the button, By pressing the long press button, the A countdown signal will be displayed to let you know when the function will be activated. When the countdown signal ends and the long press button is pressed and the finger is released from the touch panel, the function is activated, when the countdown signal ends and the finger is released from the touch panel while the long press button is pressed before the countdown signal ends, the function is not activated, when the countdown signal ends and the finger is slid from the long press button without releasing the finger from the touch panel and released from the touch panel at a position away from the long press button, the function is not activated. A touch panel is provided.

[0008] Applicable The length of time until the countdown signal ends is Even if the assigned functions perform the same processing It is preferable that the color of the countdown signal changes with each operation. Even if the assigned functions perform the same processing It is preferable that the countdown signal changes with each operation. Furthermore, it is preferable that the countdown signal goes around the long push button. Effect of the Invention

[0009] The touch panel of the present invention is a touch panel that displays an image in which a plurality of function buttons are arranged, and the plurality of function buttons are each provided with a function button that is pressed for a predetermined period of time. By The function is activated It is possible a long press button for pressing the button, By pressing the long press button, the A countdown signal will be displayed to let you know when the function will be activated. When the countdown signal ends and the long press button is pressed and the finger is released from the touch panel, the function is activated, when the countdown signal ends and the finger is released from the touch panel while the long press button is pressed before the countdown signal ends, the function is not activated, when the countdown signal ends and the finger is slid from the long press button without releasing the finger from the touch panel and released from the touch panel at a position away from the long press button, the function is not activated. As a result, in a device in which this touch panel is employed, a countdown signal is displayed for buttons that would not normally be pressed during operation to draw attention, eliminating the problem of productivity of the device in which the touch panel is installed decreasing due to pressing the wrong function button, and also eliminating the stress that comes with pressing the wrong function button.

[0010] Also, Even if the assigned functions perform the same processing By changing the length of the countdown signal or the color displayed, it is possible to provide an incentive to the operator and prevent operational errors resulting from familiarity or habits when operating the touch panel.

[0011] [Figure 1] 1 is an overall perspective view of a dicing device provided with a touch panel according to an embodiment of the present invention; [Diagram 2] This is a menu screen of a touch panel while the dicing device shown in Figure 1 is in operation. [Diagram 3] 3 is a conceptual diagram showing an embodiment of the operation of the touch panel shown in FIG. 2. [Figure 4] 4 is a conceptual diagram showing another embodiment of the function buttons of the touch panel shown in FIG. 3. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a touch panel configured based on the present invention will be described in detail with reference to the accompanying drawings.

[0013] 1 shows a dicing device 1 to which a touch panel 20 of this embodiment is applied. The dicing device 1 in the illustrated embodiment includes a substantially rectangular parallelepiped device housing 2, and includes a chuck table mechanism 3 arranged as holding means for holding a wafer W, which is a workpiece, and cutting means 4 equipped with a cutting blade 41 for cutting the wafer W held by the chuck table mechanism 3. As shown in the figure, the wafer W to be processed in this embodiment is a substantially disk-shaped semiconductor wafer having a plurality of devices formed on its surface partitioned by planned division lines, and is supported by an annular frame F via an adhesive tape T.

[0014] The cutting device 1 further includes a cassette 5 (shown by a two-dot chain line) for accommodating a plurality of wafers W, a temporary placement table 6 for carrying out and temporarily placing the wafers W accommodated in the cassette 5, a carry-in / out means 7 for carrying out the wafers W to the temporary placement table 6, a transport means 8 for rotating and transporting the wafers W carried out to the temporary placement table 6 onto the chuck table mechanism 3, a cleaning means 9 (details not shown) for cleaning the wafers W cut by the cutting means 4, a cleaning transport means 11 for transporting the cut wafers W from the chuck table mechanism 3 to the cleaning means 9, an imaging means 12 for imaging the wafers W on the chuck table mechanism 3, and a control means (not shown). The cassette 5 is placed on a cassette table 5a arranged so as to be movable up and down by a lifting means (not shown), and when the wafers W are carried out of the cassette 5 by the carry-in / out means 7, the height of the cassette 5 is appropriately adjusted.

[0015] Located within the device housing 2 is an X-axis feed means (not shown) which serves to feed the chuck table mechanism 3 and the cutting means 4 relative to one another for processing, and moves the chuck table mechanism 3 in the X-axis direction indicated by the arrow X, which is the cutting feed direction.

[0016] As shown in the figure, a touch panel 20 is provided on the device housing 2 of the dicing device 1. The touch panel 20 is connected to control means (not shown). The control means is configured by a computer, and the control means controls each operating means of the dicing device 1. The touch panel 20 is capable of displaying various menus, and an operator can give instructions to the dicing device 1 by directly touching (touching) the screen.

[0017] 2 shows a menu screen 20a when the dicing device 1 is performing cutting processing. The menu screen 20a displays an image in which a plurality of circular function buttons 21-26 are arranged. The function buttons 21-26 include, for example, a function button for displaying information about the wafer W being processed as the workpiece, a function button for displaying current processing conditions, a function button for displaying the state of the dicing device 1, and a function button for instructing an operation for replacing a cutting blade for cutting the wafer W. Each function button is provided with a letter or figure indicating a simplified function assigned to each function button, as shown by A-F in the figure (A-F in the figure are shown for convenience of explanation and differ from the actual display).

[0018] 3, a case will be described in which an operator managing the dicing apparatus 1 operates the menu screen 20a of the touch panel 20. First, a case will be described in which the operator mistakenly presses function button 25, which should be pressed when replacing the cutting blade 41, when he or she should press function button 22, which displays the processing conditions related to the cutting processing being performed in the dicing apparatus 1.

[0019] 3 shows a state where the operator's finger F touches the function button 25 displayed on the menu screen 20a of the touch panel 20 shown in step S1. As described above, the function button 25 in this embodiment is a button that is pressed when instructing an operation for replacing the cutting blade 41, and the cutting process of the dicing device 1 is interrupted and the cutting means 4 is moved to a predetermined position for replacing the cutting blade 41 by activating a function assigned to the function button 25. Incidentally, the function button 25 is a long-press button whose function is activated when pressed for a predetermined time, and even if the function button 25 is touched, the function assigned to the function button 25 is not activated immediately, and instead, as shown in the menu screen 20a of step S1 shown in FIG. 3, a countdown signal display area 251 appears around the function button 25, and a countdown signal 252 appears above the countdown display area 251.

[0020] Next, as shown in the menu screen 20a in step S2 in the figure, the countdown signal 252 extends at a constant speed in the direction indicated by the arrow R1 while the operator's finger F is touching the countdown signal display area 251. Here, it is assumed that the operator notices by looking at the extending countdown signal 252 that the function button 25 is not the function button 22 that displays the processing conditions desired by the operator, and removes the finger F from the menu screen 20a (indicated by F' in the figure) as shown in step S2. With this action, the extension of the countdown signal 252 stops, and the countdown signal 252 and the countdown display area 251 disappear from the menu screen 20a as shown in step S7 without the function of the function button 25 being activated, and the cutting processing of the dicing device 1 continues.

[0021] In contrast, a case where the worker touches the function button 25 correctly to instruct an operation for replacing the cutting blade 41 will be described. As shown in step S1 of FIG. 3, even if the worker's finger F touches the function button 25, the function assigned to the function button 25 does not immediately start because the function button 25 is a long-press button, and a countdown signal display area 251 appears around the function button 25, and a short countdown signal 252 appears at the top of the countdown display area 251, as shown in the menu screen 20a of step S1. Then, as shown in step S3, while the worker's finger F is touching the countdown signal display area 251, the countdown signal 252 extends at a constant speed in the direction indicated by the arrow R1. While the countdown signal 252 extends, the worker recognizes that the function button 25 he or she is touching is correct, and continues to touch the function button 25. In this way, the countdown signal 252 extends, and when, for example, 10 seconds have passed, the countdown signal 252 circles the countdown display area 251, i.e., the function button 25 which is a long press button, thereby visually indicating that the countdown signal 252 has ended and the function of the function button 25 will be activated.

[0022] As described above, when the countdown by the countdown signal 252 ends and the operator releases his / her finger F from the function button 25, the process proceeds to step S5, and the function for replacing the cutting blade 41 can be activated.

[0023] According to this embodiment, as described above, by making the function button 25 a long press button, the function assigned to the function button 25 does not operate simply by touching the function button 25, and the problem of productivity of the device provided with the touch panel 20 being deteriorated due to pressing the wrong function button is eliminated. Note that the present invention is not limited to making only the above-mentioned function button 25 a long press button, and the other function buttons 21 to 24, 26 may be made to be long press buttons as described above. Furthermore, in this embodiment, in addition to the above-mentioned embodiment, the following functions can be added to each function button as necessary. A more specific description will be given with reference to FIG. 3, assuming that the function is added to the above-mentioned function button 25.

[0024] As described above, the function button 25 is a long-press button, and the timing when the countdown by the countdown signal 252 ends and the function of the function button 25 is activated is visually notified, and the function can be activated. However, as the worker becomes accustomed to the work, he or she may forget to check whether or not the correct function button is being pressed while the countdown signal 252 is extending, and may realize that the wrong function button is being pressed at the timing when the countdown signal 252 ends, that is, at the stage of step S4 in FIG. 3. Therefore, in this embodiment, when the countdown signal 252 ends and the worker's finger F touches the function button 25, as shown in step S4 in FIG. 3, while keeping the finger F touching the surface of the touch panel 20, the finger F is slid sideways from the position of the function button 25 (indicated by F' in the figure) as shown in step S6, and the finger F' is released at a position away from the function button 25, the function assigned to the function button 25 is not activated.

[0025] According to the above-described configuration, even if function button 25 is pressed and held until countdown signal 252 ends, it is possible to prevent the operation of dicing device 1 from being stopped unintentionally and the operation of replacing cutting blade 41 from being started without activating the function of function button 25, thereby preventing the problem of reduced productivity.

[0026] In the above embodiment, the timing at which the countdown signal 252 ends is 10 seconds after the function button 25 is pressed. However, the present invention is not limited to this. For example, the length of time from the start of pressing the function button 25 until the countdown signal 252 extends and ends may be changed between 5 and 10 seconds. If the length of the countdown signal is constant, the worker may become accustomed to it by repeating the work, and the effect of the long press button may decrease. However, by changing the length of the countdown signal, for example, randomly, the worker is alerted to pressing the wrong function button, and the effect of the present invention can be more effectively achieved. For the same reason, the display color of the countdown signal 252 may be changed. By randomly changing the color of the countdown signal 252 every time an operation is performed, it is possible to avoid operation errors caused by accustomment or habit as much as possible.

[0027] In the above embodiment, the countdown signal 252 that starts when the function button 25 is pressed is shown to circle around the function button 25, which is a long-press button, but the present invention is not limited to this. For example, when the function button 25 shown in FIG. 4(a) is touched by the worker's finger F, a predetermined countdown signal 253, for example, light blue close to white, is displayed in the countdown display area 251 as shown in FIG. 4(b). From this, for example, as shown in FIG. 4(c) to FIG. 4(e), the color of the countdown signals 254 to 256 displayed in the countdown display area 251 is changed to a darker blue color every two seconds, and the color is changed to the darkest blue color shown in FIG. 4(e), thereby notifying the user that the countdown signal has ended. With such countdown signals 253 to 256, the same effects as those of the embodiment described above can be obtained. Furthermore, when the timing of the end of the countdown signal displayed in countdown display area 251 is indicated by a change in color, it is not limited to changing the shade of a single color as described above, but may also be indicated by a change in color, such as blue-green-yellow-red.

[0028] In the above embodiment, an example was described in which function button 25 is a long press button, but it is also possible to make all of function buttons 21 to 26 long press buttons, or it is also possible to make only some of the function buttons that could reduce productivity if pressed accidentally into long press buttons as described above.
