<p>PROBLEM TO BE SOLVED: To invalidate input by a pointing device by using an existing input device and without using a control circuit such as a switch and an interruption signal generating part. SOLUTION: A CPU which is not shown invalidates the input by a mouse (not shown) when input operation by combination of specific keys, for example, of a keyboard 32 which is not shown is performed. And the invalidated input is not reflected on cursor transfer, etc., (Yes in step S32). In the case except the above operation (No in step S32, step S34), the cursor transfer, etc., by the mouse is performed.</p> |
