Abstract

PURPOSE: To transmit a signal with X and Y-directional coordinate positions coded by detecting an electrical output signal from a piezoelectric substance piece mounted on a pen by making the pen scan on an input substrate.
CONSTITUTION: An electric signal is applied from oscillator 3 to peizoelectic substance 2. The vibration of piezoelectric substance 2 propagates to the edges of input substrate 1, so that an elastic wave travels in the X direction. When the wave surface reaching pen 5, the tip of pen 5 starts vibrating and piezoelectric- substance piece 6 outputs an electrical output signal, so that time measuring instrument 7 will measure the difference in time between the point when the electric signal originates from oscillator 3 and the detection signal from piezoelectric substance 6. On the other hand, the product with the time is the distance between piezoelectric substance 2 and pen 5. Then, the output of oscillator 3 is connected to Y-directional piezoelectric substance 2' through switch circuit 4. Alternate Y- directional piezoelectric substances 2 and 2' are driven to detect the position of pen 5
