OPERATION INPUT DEVICE AND INFORMATION DISPLAY DEVICE
First Claim
1. An input device connectable to an information display device having a first surface with a display unit, the input device comprising:
- a planar piezoelectric element with a piezoelectric film including opposing first and second surfaces, a first electrode disposed on the first surface and a second electrode disposed on the second surface, the piezoelectric element generating a detection signal corresponding to a position of a pressing input; and
a controller coupled to the planar piezoelectric element and configured to generate operation input information based on the detection signal,wherein the planar piezoelectric element is positioned to be arranged adjacent to a second surface of the information display device opposite the first surface when the information display device is connected to the input device.

Abstract
An operation input device has a housing including a concave portion in which an information display device is accommodated. A piezoelectric element of a flat film shape and a control IC connected to the piezoelectric element are built in a base portion of the housing. The control IC is connected to a device IC of the information display device. When a user'"'"'s finger touches an attachment region of the piezoelectric element in the base portion of the housing, a detection signal corresponding to the touch position and a pressing amount is outputted from the piezoelectric element. The control IC generates operation information based on the detection signal, and outputs the operation information to the device IC of the information display device. The device IC shows display corresponding to the operation information.
