Abstract
A displacement between an input point on a touch-sensitive panel and a display point on a display panel must be reliably corrected by a simple, inexpensive structure. A transparent touch-sensitive panel having a coordinate system formed on its surface for locating the position of a point input and a LCD panel having a coordinate system for locating the position of a display point corresponding to the input point on the touch-sensitive panel are laminated together and swingably attached to a main body. A rotation angle of the touch-sensitive panel and the LCD panel with respect to the main,body is detected by an angle detector. The abscissa and ordinate values of an input point in the coordinate system of the touch-sensitive panel are corrected according to a rotation angle detected by the angle detector and a distance between the surfaces of two panels and displayed in the display coordinate system of the LCD panel.
