Abstract
PURPOSE: To simplify the unit without using special pen for the input pen, by avoiding the stray current through the provision of the charged electrode pair diffrent in the opposing direction at two resistive films placed on the input plate, eliminating the distortion of input picture and extending the effective input area.
CONSTITUTION: On the insulating base plate 22 of the input plate 21 of the coordinate input unit, the resistive film 23 is adhered, the frame type insulating spacer 24 is adhered on the resistive film 23, on this spacer 24, the flexible film 27 adhering the resistive film 26 under the insulating film 25 is extended and adhered. Further, the electrodes X, X' are placed at the external ridge opposing each other of the resistive film 23 and the opposing electrodes Y, Y' almost orghogonal to the electrodes X, X' is placed at the opposing external ridge of the resistive film 26. The input plate 21 with this constitution is used for the coordinate input unit, the opposing electrodes X, X' provided to the two resistive films 23, 26 and Y, Y' avoid the distortion of input picture produced due to stray current and extend the effective input area, and the copy of input picture can easily be obtained without using any cord for the input pen.
