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.

Description

technical field [0001] The present invention relates to a rotary encoder, and more particularly to a rotary encoder that is used, for example, in computer peripherals such as a mouse, mobile phones, and vehicle-mounted electrical Angle) and the signal of the changing direction (rotational direction) of the rotary encoder. Background technique [0002] As an example of the prior art that becomes the background of the present invention, there is, for example, the following rotary encoder (for example, refer to Patent Document 1), which is characterized in that it has a columnar or cylindrical shape made of an insulating material and can rotate. , or a truncated cone-shaped rotating body; a code pattern arranged on the outer surface of the rotating body; a plurality of contact sheets in contact with the code pattern are provided with a code pattern on the circumferential surface of the rotating body, and on an end surface of the rotating body A ratchet concave-convex portion i...
