Abstract

PURPOSE: To execute easily a work for attaching a touch panel switch to the front of a CRT by generating a coordinate transforming expression by calculating a shift of the touch panel switch and a display picture, and converting a switch coordinate data to a display picture coordinate value.
CONSTITUTION: At the time of assembling, X and Y axes of a transparent touch panel 1 are attached to X and Y axes of a picture of a CRT 2, and thereafter, reference positions P, Q, R and S whose coordinate values are clear are depressed, and a contact coordinate data of the touch panel switch 1 corresponding to these reference positions is stored in a RAM 5. A CPU 3 generates a coordinate transforming expression by calculating a shift of the X and Y axes of the touch panel switch 1 and the X and Y axes of the CRT picture from said contact coordinate data and the coordinate value of the reference position. Thereafter, when depressing the touch panel switch, a coordinate data from a contact detecting circuit 7 is converted to a coordinate value of the picture by using the transforming expression. In this way, a complicated alignment of the time for attaching the switch becomes unnecessary.
