Abstract:
PURPOSE: To attain the sure and correct input of each mark by providing a means which produces an alarm tone right before the reference time elapses from the start of marking.
CONSTITUTION: A signal generator 21 contained in a touch pen 1 works in response to the writing pressure when the marking is carried out on the paper, etc., by the pen 1. Then the signal is produced while the writing pressure is applied and sent to a timer circuit 22.

A marking person decides whether he/she should finish the marking action or not based on an alarm tone. Thus the correct input is secured for each mark.
