<p>PURPOSE:To eliminate the need for measurement of deviation for each product by using a coordinate detection fixed element and a conversion means. CONSTITUTION:Coordinates (Xd0, Yd0), (Xd1, Yd1) of points P0, P1 of coordinate detection fixed and elements 9, 11 are detected. Then the length of line segments whose value is decided by specifying the points P0, P1, that is, the length of P5P0, P5P1, P1P0 is calculated and the result is stored in a prescribed area of a RAM39. The detection tip 21 of an input pen 19 is abutted on a coordinate input panel 5 and when a pen switch 23 is closed, a CPU23 switches selection circuit SEL25 to the input pen 21 side, a scanning pulse is supplied to electrode lines in directions Xd, Yd to specify a coordinate input point P2. Then the quantity of the Yd coordinate axis components Yd1, Yd0 of the points P0, P1 is compared, and in case of Yd1<Yd0, the length of line segments P6P0, P2P6 is calculated to calculate Xc3, Xc4. In case of Yd1>Yd0, the length of line segments P2P7, P7P0 is calculated to calculate Xc3, Yc4.</p> |
