OPERATION INPUT DEVICE

摘要

In an operation input device, a supporting part supports an operation part to be displaceable with respect to the base part, and a reaction force generating part generates reaction force in an axial direction coaxial with the displacement direction in response to the displacement. The supporting part includes: a support member having: one end connected to the base part and another end protruded from the base part; and a plurality of plate springs respectively having a plate surface perpendicular to a center axis of the support member, arranged radially around the center axis, and a tip in a radial direction connected to the operation part. The reaction force generating part includes: an electromagnet generating magnetic force in an axial direction parallel to the center axis of the support member; and a magnetic member arranged opposite to the electromagnet to receive magnetic force to apply reaction force to the operation part.

1. An operation input device comprising:
an operation part that is operated by a user; a supporting part that supports the operation part to be displaceable with respect to a base part; and a reaction force generating part that generates a reaction force in a direction coaxial with a displacement direction of the operation part in response to a displacement of the operation part, wherein the supporting part includes:
a support member that has one end connected to the base part, and has an other end protruded from the base part; anda plurality of plate springs, located at the other end of the support member, that respectively have a plate surface perpendicular to a center axis of the support member in a protruding direction, and that are respectively arranged in a radial direction around the center axis in the protruding direction and have a tip end connected to the operation part, and wherein the reaction force generating part includes:
an electromagnet that is arranged at one of the base part and the operation part to generate a magnetic force in an axial direction parallel to the center axis of the support member; anda magnetic member that is arranged at a position opposite to the electromagnet at the one of the operation part and the base part, and that receives the magnetic force generated by the electromagnet so as to apply a reaction force to the operation part.
