徴とするカム伝達機構。[Scope of Claim for Utility Model Registration] A disc-shaped cam plate having a cam groove that guides a position regulating pin connected to the moving object in order to move the moving object to a position according to the operation mode, and a motor. A cam transmission mechanism comprising: an intermediate gear that transmits rotational driving force; and a drive transmission gear that transmits the rotational driving force of the motor to the cam plate via the intermediate gear to rotate the cam plate, Teeth and recesses distributed in the circumferential direction at predetermined intervals are provided in parallel on the outer periphery of the cam plate, and the teeth mesh with the teeth of the cam plate over a predetermined angular range on the outer periphery of the drive transmission gear. and a stepped portion that fits into the concave portion of the cam plate in a state where the rotation of the drive transmission gear is not hindered over an angular range in which the tooth portion does not mesh with the tooth portion of the cam plate. A tooth portion that meshes with the intermediate gear is provided around the entire circumference of the drive transmission gear, and when the concave portion of the cam plate and the stepped portion of the drive transmission gear are engaged, the motor is stopped and the moved object is stopped. A cam transmission mechanism characterized in that the cam groove is formed so that the body stops at a position depending on the operation mode.
