Abstract
A pedal device for performance (1) has a pedal (4) where a player can perform a depressing operation with his/her foot. A rod (6) is movable in an axial direction in accordance with the depressing operation of the pedal (4). A detecting mechanism detects an amount of movement of the rod (6) and outputs a detection signal corresponding to the amount of movement. The detecting mechanism has an optical sensor (10) that is a non-contact sensor detecting an amount of displacement in the axial direction L of the rod (6) in a non-contact manner.
Claims8
A pedal device for performance, comprising:
- a pedal where a player can perform a depressing operation with his/her foot;
- a rod movable in an axial direction in accordance with the depressing operation of the pedal;
- a detecting mechanism detecting an amount of movement of the rod in a non-contact manner and outputting a detection signal corresponding to the amount of movement, the detecting mechanism position adjacent the rod and pedal connection;
- a stopper member, including an upper portion and a lower portion, is attached to the rod, the upper portion of the stopper member including an abutting portion that abuts against an outside portion of the housing when the pedal is depressed to a maximum position, and further movement of the rod is restricted by the abutting portion abutting the outside portion of the housing, the lower portion of the stopper member passing through the housing and extending in an axial direction within the housing;
- and
- a member to be detected attached to the lower portion of the stopper member so as to be movable integrally with the rod and the stopper member inside of the housing, an axial gap between the member and the detecting mechanism that enables the detecting mechanism to detect positions of the rod and the stopper member;
- wherein the detecting mechanism includes a non-contact sensor detecting an amount of displacement in the axial direction of the rod in a non-contact manner.
