Pressing Force Sensor
First Claim
1. A pressing force sensor comprising:
- an expandable and contractible film;
a pressing force detecting resistor membrane on a portion of a first surface of the expandable and contractible film; and
a support adjacent the expandable and contractible film, the support having a recess adjacent the portion of the expandable and contractible film where the pressing force detecting resistor membrane is located, whereina change in resistance value of the pressing force detecting resistor membrane caused by a pressing force exerted on the first surface of the expandable and contractible film that deforms the pressing force detecting resistor membrane is detected.

Abstract
A pressing force sensor that includes an expandable and contractible film, pressing force detecting resistor membranes formed on a portion of a main surface of the film, and a support disposed along the main surface of the film. The support is provided with recesses or holes with openings located in areas where the pressing force detecting resistor membranes on the main surface of the film are located. In the pressing force sensor, when a pressing force is exerted on the main surface of the film, the film is expanded with a pressing force detecting resistor membrane. As a result, the pressing force detecting resistor membrane is deformed, and a change in resistance value of the pressing force detecting resistor membrane corresponding to the deformation is detected.
