Claims

[Claims for Utility Model Registration] 1. Consisting of a microswitch and an actuator that has an operating surface for driving the microswitch and is always biased in a certain direction, and that resists the biasing force by inserting a cassette. 1. A cassette detection actuator mechanism, characterized in that when the actuator is driven, the microswitch contacts and operates over a range of the actuator drive direction on the action surface. 2. The actuator has a circular arc surface with a constant radius from the center of rotation, and is configured so that it is always biased in a constant direction around the center of rotation and stops at a predetermined position □, and the arc surface is The cassette detection actuator tough mechanism according to claim 1, characterized in that it is configured to serve as an operating surface for driving the microswitch.
