In addition, by pressing the color tablets 6a to 6g, the color of the image to be input by handwriting is selected.
[0029]
The tip of the stylus pen 3 is a light emitting unit 3a. The light emitting unit 3a emits a designated color when the stylus pen 3 contacts the color tablets 6a to 6g. For example, by incorporating the light emitting circuit 30 shown in FIG. 4 into the stylus pen 3, the light emitting unit 3a emits light.
[0030]
The light emitting circuit 30 is connected to a red laser diode (hereinafter referred to as an LED) 31, a first resistor 32 connected in series to the red LED 31, and connected in series to the first resistor 32. A first switch 33. The light emitting circuit 30 includes a blue LED 34, a second resistor 35 connected in series to the blue LED 34, and a second switch 36 connected in series to the second resistor 35. Prepare.

The position data, color data, and timing data read from the card 12 are temporarily stored. The control unit 2 controls the LCD driver 10 according to the reproduction mode, and causes the LCD 11 to display an image based on the position data, color data, and timing data stored in the RAM 7.
[0036]
The reproduction mode includes a handwriting input process reproduction mode and a completed image reproduction mode. In the completed image reproduction mode, the handwriting input ends, and the completed image is displayed on the LCD 11. On the other hand, in the handwriting input process reproduction mode, a process in which an image is handwritten is displayed on the LCD 11. For example, by changing the pixels of the LCD 11 in order from the pixel at the position indicated by the position data generated earlier to the color indicated by the corresponding color data, the process of handwritten input of the image is performed on the LCD 11. Is displayed.
[0037]
Specifically, for example, as shown in FIG. 5, when two horizontal lines having the same length and parallel to each other are handwritten by drawing the upper line from the left and then drawing the lower line from the left, First, as shown in FIGS. 6A to 6C, the upper line is gradually displayed from the left, and then, as shown in FIGS. 6D to 6F, the lower line is displayed from the left. By being gradually displayed, the process of handwriting input is displayed.
