Title:
PRESSING INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/070010
Kind Code:
A1
Abstract:
This pressing input device is an input device the reaction force characteristic of which when a single metallic inverted dome is pushed downward is a first reaction force characteristic that reaction force increases monotonously from an initial position to a maximum position, decreases monotonously from the maximum position to a minimum position, and increases monotonously from the minimum position, the reaction force characteristic of which when a single elastic member is pushed downward is a second reaction force characteristic that reaction force increases monotonously from the initial position, and the reaction force characteristic of which when an operation member is displaced downward is a synthesized reaction force characteristic obtained by synthesizing the first reaction force characteristic and the second reaction force characteristic, wherein a plate-shaped intermediate member having a larger area than the elastic member when viewed from above is provided between the metallic inverted dome and the elastic member, and the elastic member comprises a metallic plate spring member having a peripheral portion that is in contact with the plate-shaped intermediate member and a central portion that is away from the plate-shaped intermediate member.
