<p>PURPOSE:To allow the input position and the display position to an operator to be coincident without fail by correcting the position of display information corresponding to the input information with the display information detecting means of an input pen. CONSTITUTION:At the central part of a ring-shaped vibrator 112 of a vibrating pen 3, an optical sensor 113 is provided so as to detect a light transmitted through a horn part 114, reflected by the reflecting surface of an indicator 11' and the presence and absence of the display can be detected by the intensity of the light inputted to the optical sensor 113. When a display dot 121 is detected by the optical sensor 113, the vibrator 112 is driven, the vibration inputted to a vibration transmission plate 8 is processed, and the input coordinates value is obtained. By obtaining the difference in the coordinates of the display point found out beforehand, the correcting control quantity of the display position can be obtained. Thus, the input position and the display position can be made coincident with each other to an operator.</p> |
