Abstract
PURPOSE: To convert the coordinate information in succession into electric signal with fidelity, by means of the resistor adhered on one surface of pressure sensing conductive rubber sheet and the conductor adhered to another surface.
CONSTITUTION: On the both sides of the pressure sensing conductive rubber sheet 20, the resistance plate 21 and the conductor plate 22 are closely provided. Diode groups 31, 32, 34, 35 are connected to the resistance plate 21 and AC voltage V is applied to the drive terminals 12 and 13. When the voltage V is positive, a given potential gradient is present toward Y and toward X when negative. When pencil pressure is fed to the conductor plate 22 with the input pen 8, the resistance of pressed part of the sheet 20 is decreased, and the negative voltage corresponding to the X coordinate is picked up from the terminal 17 and the positive voltage corresponding to the Y coordinate is picked up from the terminal 18. Since insulating particles are not used, consecutive information can be converted with fidelity.
