An image of a cursor 80 is displayed at substantially the center of the image. Thereafter, when the stylus pen 11 is sequentially moved to the coordinate input area 1D side, the cursor 80 moves on the display screen 7A as indicated by the arrow X. During this operation, if the coordinate information 104 is determined to be outside the valid coordinate area of the display screen 7A, a cursor erasure signal is output from the cursor control unit 5, and the cursor 80 is erased from the display screen 7A. At this time, the coordinate conversion unit 14 determines that the coordinate information 104 is the effective coordinate area of the display screen 17A, and the cursor 80 is displayed on the display screen 17A. Thereafter, the cursor 80 is displayed on the display screen 17A in a state moved in the direction indicated by the arrow Y in accordance with the operation of the stylus pen 11.

As described above, in the present embodiment, even if two display devices 7 and 17 are connected to the coordinate input device 1, the display screen 7A is switched from one display screen 7A to the other according to the operation of the stylus pen 11 without performing the image switching operation. Can be displayed while sequentially moving the cursor 80 on the display screen 17A, and the display screens 7A and 17A can be operated as if they were one continuous display screen, which can contribute to improvement in operability. .

When the switch unit 1B is operated while the cursor 80 is displayed on the display screen 7A, the switch information 105 is input to the switch information input unit 8, and the coordinates of the display position of the cursor 80 are displayed on the tube surface coordinate information. The data is transferred from the data input / output unit 9 to the computer 10 as 103.
