<p>PURPOSE:To adjust the origin of a touch panel and the difference of a detection range in each product without requiring a complicated adjusting mechanism. CONSTITUTION:At the time of inputting an origin depression signal 11, an original point coordinate voltage storing memory 6 receives the output voltage of a position to be an original point on a touch panel 1 through an original point writing buffer 5 and stores the received contents. An original point correcting arithmetic circuit 7 corrects an output voltage sent from a buffer 4 by the output voltage stored in the memory 6. At the time of inputting a maximum coordinate depression signal 12, a detection range voltage storing memory 9 receives a maximum coordinate output voltage corrected by the output voltage stored in the memory 6 by the circuit 7 throgh a detection range writing buffer 8 and stores the received contents. A depression point correcting arithmetic circuit 10 corrects the depression point output voltage corrected by the circuit 7 by the output voltage stored in the memory 9 and outputs the corrected contents as a depressed coordinate position.</p> |
