Abstract

PURPOSE: To detect the position of a moving object by arranging a piezoelectric tape or wire with separated electrodes at a place where the moving object moves, converting air pressure blown from the moving object into a signal by the piezoelectric object and detecting the signal.
CONSTITUTION: A detecting wire 1 is formed by arranging electrodes 7 on both sides with a piezoelectric object 6 as a center, providing one side electrode at certain intervals to detect positions and connecting each electrode by a lead wire 4. As a voltage is generated by air pressure given by the air blowing device 3 of a moving object 2 at an electrode position where air is blown against the piezoelectric object of the detecting wire 1, the position of the moving object 2 can be detected by supplying the signal of the voltage to a detecting circuit 3 via the lead wire 4.
