Title:
ELECTROSTATIC CAPACITANCE TYPE INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/053682
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrostatic capacitance type input device that combines: having a switch that is easy to handle and has a rotary dial or push button; and using an electrostatic capacitance touch sensor with a simple design. This electrostatic capacitance type input device comprises: an operation panel; a sensor sheet attached to the rear surface side of the operation panel; and a switch including at least one of a rotary dial and push button. A base material sheet of the sensor sheet is provided with a touch sensor electrode for detecting a touch operation on a surface of the operation panel by a change in electrostatic capacitance, and a detection electrode for detecting a switch operation on the switch by a change in electrostatic capacitance. The switch is provided with a conductor having a distance to the detection electrode that changes by the switch operation, and the switch operation on the switch is detected from a change in electrostatic capacitance caused by the change in distance between the detection electrode and the conductor.
