Abstract

PURPOSE: To evade the report of the wrong coordinates and to realize the continuous use of a touch panel by excluding an abnormal element pair out of a coordinate detecting process in case the abnormal element is detected during a normal coordinate detecting action.
CONSTITUTION: An abnormal light shielding detecting part 94 of a processor 90 of a touch panel device decides the presence or absence of the abnormal detection light from the contents of a light shielding decision result table 72. Then a counter of a counting means 80 calculates continuously the scan frequency of an element pair whose abnormal light shielding states are decided for each axis. In case ≥2 axes have the element pairs decided as abnormal light shielding are detected, the scan frequency of the utmost left element pair is counted. When this count value exceeds a fixed level, the element pair is decided abnormal and registered into an abnormal element table 73. An alarm means 75 refers to the contents of the table 73 and turns on an LED 1 as a 1st alarm. Then the element pair registered in the table 73 is excluded out of the subsequent coordinate deciding processes of a coordinate deciding process part 93.
