<p>PROBLEM TO BE SOLVED: To enhance a degree of freedom of a mounting position of a light receiving/emitting means on a coordinate input surface. SOLUTION: Light shielding position information (u11 to u51), (u12 to u52 and coordinates of reference points in sensor heads 1, 2 when an object is inserted into reference points (x1, y1) to (X5, y5) are stored in first storage parts 3, 4. Coefficient calculating means 5, 6 calculate coefficients (c11 to c51), (c12 to c52) by every sensor head on the basis of the coordinates of the reference points and the light shielding position information and stores them in second storage parts 7, 8. A prescribed operation 9 is performed by using pieces of information u1, u2 corresponding to shielding positions of light generated in each of the sensor heads 1, 2 by the light shielding object inserted in the case of input of the coordinates and the coefficients stored in the second storage parts 2 by and a coordinate (x, y) into which the light shielding object is inserted is outputted.</p> |
