O Utility Model Registration Claims A base in which two groups of contacts (each having two fixed contacts) are provided concentrically at an angular interval of approximately 180 degrees, and rotates in conjunction with the rotation of a rotating member. a rotation detection sensor comprising a cap that is provided with a movable contact that moves, and is configured such that the movable contact comes into contact with one and/or the other fixed contact of each contact group in an order according to the rotation direction; When the movable contact contacts one of the contact groups during rotation in one direction, a signal indicating rotation in the one direction is generated; and when the movable contact contacts the other of the contact group during rotation in the opposite direction, the movable contact outputs a signal indicating the rotation in the opposite direction. and a discrimination circuit that outputs a signal indicating the rotation of the movable contact. A rotation direction detection device characterized by outputting a signal indicating a rotation direction.

Claims

[Scope of utility model registration request]

A base is provided with two contact groups having at least two non-concentrically provided fixed contacts at an angular interval of about 180 degrees, and a movable contact that rotates in conjunction with the rotation of the rotating member, A cap configured such that the movable contact comes into contact with one and/or the other fixed contact of each of the contact groups in an order according to the direction of rotation, and the movable contact rotates in one direction toward one of the contact groups. a discrimination circuit that outputs a signal indicating rotation in the one direction when the movable contact contacts the other of the contact groups when the movable contact rotates in the opposite direction; When the movable contact rotates from the neutral position and contacts one fixed contact of the contact group and then contacts the other fixed contact, a signal indicating the rotation direction is output from the discrimination circuit.
