When the wireless dongle 20 detects that a predetermined operation (for example, a pressing operation of a registration button not shown in the drawing) is performed with the stylus pen 2, the wireless dongle 20 determines to add a new stylus pen 2. If the stylus pen 2 is not added (S11: NO), the process proceeds to step S15.

  When adding the stylus pen 2 (S11: YES), the wireless dongle 20 performs wireless communication with the new stylus pen 2 and acquires an identifier from the stylus pen 2, thereby recognizing the stylus pen 2 (step). S12).

  Next, the wireless dongle 20 assigns a pen ID to the recognized stylus pen 2 (step S13). For example, when 1 to N pen IDs are assigned to the registered stylus pens 2, 2,..., The wireless dongle 20 sets N + 1 as the pen ID for the new stylus pen 2 recognized in step S12. assign. The main control unit 11 of the touch panel device 1 acquires the newly registered identifier and pen ID of the stylus pen 2 from the wireless dongle 20 and stores them in the pen management table in association with each other.

  Next, the main control unit 11 assigns a display color to the newly registered stylus pen 2 (step S14). In the present embodiment, a color code is predetermined for each display color (that is, black, red, blue, green, yellow, and custom color) that can be assigned to each stylus pen 2. In step S14, the main control unit 11 selects the color code having the smallest value from among the color codes excluding the assigned display color code. The main control unit 11 assigns a display color to the stylus pen 2 by storing the pen ID of the stylus pen 2 to be assigned in the pen assignment table in association with the selected color code.

  Next, the main control unit 11 determines whether or not a predetermined operation for displaying the pen setting screen 100 on the display panel 1A has been received (step S15). If it is determined that a predetermined operation for displaying the pen setting screen 100 is not accepted (S15: NO), the main control unit 11 returns the process to step S11.

  When it is determined that a predetermined operation for displaying the pen setting screen 100 has been received (S15: YES), the main control unit 11 displays the pen setting screen 100 on the display panel 1A (step S16).

For example, the main control unit 11 displays a mark M indicating prohibition of selection on an icon indicating a display color assigned to another stylus pen 2 among the icons 131 to 135 corresponding to each display color. Then, the process of stopping the selection of the display color through the icon is performed.

  Next, the main control unit 11 determines whether or not the display color assigned to the stylus pen 2 has been selected on the pen setting screen 100 (step S19). When the pen setting screen 100 is closed without selecting the display color to be assigned to the stylus pen 2 (S19: NO), the main control unit 11 returns the process to step S11.

  When determining that the display color to be assigned to the stylus pen 2 has been selected (S19: YES), the main control unit 11 assigns the display color to the stylus pen 2 (step S20). Specifically, the display color is assigned to the stylus pen 2 by storing the pen ID of the assignment target stylus pen 2 in the pen assignment table in association with the selected display color and color code.

FIG. 8 is a flowchart showing a procedure of processing executed by the touch panel device 1 when the connection of the stylus pen 2 is released. The main control unit 11 of the touch panel device 1 determines whether or not to release the connection with the stylus pen 2 (step S21). For example, when it is detected that a predetermined operation (such as a pressing operation of a registration release button not shown in the figure) is performed with the stylus pen 2, or wireless communication between the wireless dongle 20 and the stylus pen 2 is performed. The main control unit 11 determines that the connection with the stylus pen 2 is to be released, for example, when it has been interrupted for a predetermined time or longer.
When it is determined that the connection with the stylus pen 2 is not released (S21: NO), the main control unit 11 ends the process according to this flowchart.

  When it is determined that the connection with the stylus pen 2 is to be released (S21: YES), the main control unit 11 deletes the identifier of the corresponding stylus pen 2 from the pen management table and also registers the pen ID registered in the color assignment table. Is deleted (step S22).
