PURPOSE:To prevent the generation of dislocation caused by a misoperation for designating a coordinate by inhibiting the correction of coordinate information except a case when it coincides substantially with a value generated at the time of a threshold position at the time when an instructing means abuts on a guiding member. CONSTITUTION:As for the correction of coordinate information, when a coordinate being the same substantially is designated continuously plural times, it is regarded as the designation of a position where an original sheet is brought into contact with a guiding member 113 and the coordinate information is corrected. However, the case that the same coordinates are inputted plural times continuously even when an operator does not intend, due to an operator's misoperation, etc., may be happened. Therefore, by checking the designated coordinate, the correction of the coordinate is inhibited except the time when it coincides with a value generated at the time of a threshold position at the time when a stylus pen 120 abuts on the member. In such a way, the generation of the dislocation caused by the misoperation for designating the coordinate can be prevented. |
