Claims

[Claims for Utility Model Registration] A rotary solenoid that rotates approximately 45 degrees when the drive pulse is at a high level and returns to its original position when the drive pulse reaches a low level; A first rotating plate that rotates together with the rotating shaft of this rotary solenoid; The rotating surface faces the rotating surface of the first rotating plate,
a second rotary plate that rotates to follow the rotation of the first rotary plate in one direction, and is free to rotate in the other direction; and an axis of the rotary plate. The waveguide rotates integrally with the waveguide, and when in the locked state, engages with the second rotating plate to restrict rotational movement in the one direction, and when in the unlocked state, the second rotating plate engages with the second rotating plate. The mechanism is a mechanism that allows rotation of the plate in the one direction, and is driven by the rotary solenoid, and maintains the unlocked state in an initial section when the rotary solenoid starts rotating, and the rotary solenoid passes through the section. and an overrun prevention mechanism that is controlled to a locked state to restrict the second rotating plate at a predetermined angular position; and an elastic member biasing the rotating peripheral surface of the cam that rotates integrally with the second rotating plate. In the initial state of the rotating shaft, the roller is pressed against a recess formed on the rotating peripheral surface of the cam, and the rotating shaft is moved approximately 45° from the initial state.
° When rotated, the large diameter part of the rotating peripheral surface corresponds to the roller, and when passing through this, the roller urges the rotation, and the roller fits into a similar recess at a position 90 degrees from the recess. A waveguide switching device characterized by comprising a cam-shaped positioning mechanism.
