Title:
入力装置及び入力システム
Document Type and Number:
Japanese Patent JP7426562
Kind Code:
B2
Abstract:
An input device includes a detection surface configured to be operated by an operation body, a first fixed electrode, a movable electrode, first and second terminals configured to be connected to an outside of the input device, and a direct-connection line electrically connecting the movable electrode to the second terminal via no capacitor. The movable electrode has a lower surface facing an upper surface of the first fixed electrode to be capacitively coupled to the first fixed electrode. The movable contact is displaceable to approach the first fixed electrode in response to a pressing of the detection surface by the operation body. The first terminal is configured to output, to the outside of the input device, a first electric signal containing a change in a capacitance between the first fixed electrode and the movable electrode. The second terminal is configured to output, from the movable electrode to the outside of the input device, a second electric signal containing a change in a capacitance between the operation body and the movable electrode. This input device improves the detection sensitivity to detect approximating or contacting the input device by the operation body.
