Abstract
A handwritten data input device has a coordinate detection tablet for detecting writing data input by handwriting using an input pen and a program storage medium. When a predetermined preprocess is required for an input process to accept writing data input by handwriting from the tablet, useless handwritten input can be effectively avoided when the preprocess has not been completed. In the handwritten data input device, a CPU determines whether the preprocess has been completed when the input pen approaches the tablet and, if the preprocess has not been completed, drives a buzzer to generate an alarm tone, thereby notifying the operator that the handwritten input is invalid in advance.
