Next, the operation of the numerical value input device 1 of the present embodiment and the machine tool 10 including the same will be described with reference to FIGS. 5 to 8.

When inputting a numerical value using the numerical value input device 1 of the present embodiment and the machine tool 10 including the same, the input detection unit 52 monitors whether there is any input from the touch panel 2, the keyboard 3, or the external input means 6. To do. As a result of the monitoring, when the fixed input button 23c is touch-selected on the touch panel 2 or when the key for instructing the fixed input of a numerical value is pressed on the keyboard 3 (step S1: YES), the fixed input processing unit 55. Executes the fixed input process shown in FIG.

Further, when an arbitrary cell is touch-selected on the touch panel 2 or an arbitrary direction key is pressed on the keyboard 3 (step S2: YES), the movement input processing unit 53 causes the movement input processing shown in FIG. To execute. Furthermore, when the numeric button 23a is touch-selected on the touch panel 2, when the numeric key is pressed on the keyboard 3, or when the barcode for numeric input is read by the external input means 6 (step S3: YES). ), and the numerical value input processing unit 54 executes the numerical value input processing shown in FIG. Hereinafter, each input process will be specifically described.

If no input is performed (step S1: NO, step S2: NO, step S3: NO) and an instruction to end the numerical value input process is given (step S4: YES), this process is ended. ing.

In the fixed input processing shown in FIG. 6, first, the fixed input processing unit 55 acquires the numerical value of the cell that is currently active from the numerical value storage unit 43 (step S11) and temporarily stores it from the numerical value buffer 45. The numerical value that has been read is acquired (step S12). Then, the fixed input processing unit 55 calculates a new numerical value according to the input method selected by the touch panel 2 or the keyboard 3 (step S13) and stores it in the numerical value storage unit 43 as the numerical value of the active cell (step S14). ..

As a result, the input method for inputting a numerical value into the cell is seamlessly selected from both the touch panel 2 and the keyboard 3, and the numerical value is input according to the selected input method. After execution of step S14, the fixed input processing unit 55 commands the display control unit 51 to hide the numerical value input pad 23, and ends the fixed input process.

Next, in the movement input processing shown in FIG. 7, first, the movement input processing unit 53 determines whether or not the numerical value input pad 23 is displayed on the touch panel 2 (step S21). As a result of the determination, when the numerical value input pad 23 is displayed on the touch panel 2 (step S21: YES), the numerical value input pad 23 is hidden (step S22). As a result, even while inputting a numerical value into the numerical value input pad 23, the numerical value input pad 23 is automatically hidden only by touching an arbitrary cell or pressing an arbitrary direction key. It becomes easier to select and move, improving operability.

Subsequently, the movement input processing unit 53 determines whether it is a touch input from the touch panel 2 or a key input from the keyboard 3 (step S23). If the result of this determination is a key input from the keyboard 3, the movement input processing unit 53 acquires from the cell information storage unit 44 the adjacent cell information for the cell that was active when pressed (step S24), Based on the adjacent cell information, it is determined whether or not there is a cell in the moving direction corresponding to the pressed direction key (step S25).

Then, when there is a cell in the instructed movement direction (step S25: YES), the selection information of the movement destination cell is set to active (step S27), and active display is performed (step S28). On the other hand, when there is no cell in the instructed movement direction (step S25: NO), the movement input processing unit 53 executes a predetermined exception process (step S26). Examples of this exception processing include processing of not moving from the current cell and processing of moving to the first cell of the next row, but are not particularly limited.

Subsequently, the movement input processing unit 53 monitors whether or not any input is made within a predetermined time (step S29). Then, when a predetermined time has elapsed without any input, the movement input processing unit 53 displays the numerical value input pad 23 (step S30).

On the other hand, if the result of determination in step S23 is touch input from the touch panel 2, the movement input processing unit 53 sets the selection information of the touch-selected cell to active (step S31) and makes active display (step S31). S32). This makes it possible to move cells seamlessly from the touch panel 2 and the keyboard 3. After that, the movement input processing unit 53 automatically displays the numerical value input pad 23 (step S30), so that the numerical value input work can be immediately executed.

Next, in the numerical value input process shown in FIG. 8, first, the numerical value input processing unit 54 determines whether or not the numerical value input pad 23 is displayed on the touch panel 2 (step S41). As a result of the determination, when the numerical value input pad 23 is already displayed on the touch panel 2 (step S41: YES), the numerical value input processing unit 54 temporarily saves the input numerical value in the numerical value buffer 45 ( In step S43), the numerical value in the numerical value buffer 45 is displayed in the numerical value display field 23b (step S44).

As a result, both the numerical value input from the touch panel 2 and the numerical value input from the keyboard 3 are displayed on the numerical value input pad 23 as a unified graphical user interface. For this reason, the movement of the user's line of sight is reduced, and the work efficiency and work speed related to numerical value input are improved.

Further, in the present embodiment, not only the numerical value input from the touch panel 2 or the keyboard 3 but also the numerical value input from the external input means 6 is displayed on the unified graphical user interface. For this reason, since a numerical value can be input without manual input such as a touch operation or a key operation, erroneous input of a numerical value is prevented.

As a result of the determination in step S41, when the numeric input pad 23 is not displayed on the touch panel 2 (step S41: NO), the numeric input processing unit 54 displays the numeric input pad 23 (step S42). As a result, even when the numerical input pad 23 is not displayed on the touch panel 2, the numerical input pad 23 is automatically displayed only by inputting a numerical value from the keyboard 3, so that the operability is improved.
