<p>PURPOSE:To inhibit an input device such as a keyboard, etc., at the time of operating a tablet. CONSTITUTION:When an operator grips a pen 5 with his hand, a switch 6 is depressed and a detecting signal 10 is sent out as a detecting signal 11 to a tablet controller 3 through a tablet 4, and this tablet controller 3 sends out a control signal to a CPU 1 through an input control part 2. Accordingly, the CPU 1 makes a keyboard lock part 7 active through an input control part 2, by which an input of a key input signal 13 from a keyboard controller 8 is inhibited, and the tablet 4 sends out coordinate value information read out with the pen 5 to the CPU 1.</p> |
