Title:
ROTARY ENCODER
Document Type and Number:
WIPO Patent Application WO/2015/177945
Kind Code:
A1
Abstract:
Provided is a rotary encoder allowing further size-reduction and cost-reduction to be achieved compared to prior art. The rotary encoder (10) comprises a base member (12), a first fixed contact member (14) provided on the base member (12), a plurality of second fixed contact members (16, 18) provided so as to leave a space to the first fixed contact member (14), a rotor member (20) rotatably supported by the base member (12), and a rotating contact member (22) having protruding and recessed portions in the rotation direction and rotating together with the rotor member (20). The first fixed contact member (14) is always in contact with the rotating contact member (22), and, through the rotation of the rotor member (20), the second fixed contact members (16, 18) become caught and released by the protruding and recessed portions of the rotating contact member (22), thereby bringing the rotating contact member (22) and the second fixed contact members (16, 18) into contact to turn the electrical connections between the rotating contact member (22) and the second fixed contact members (16, 18) on and off while giving rise to a clicking feel.
