Claims

[Claims for Utility Model Registration] A cam gear pin that continuously rotates in the same direction during loading, unloading, stop, and play operations, and a cam groove that cooperates with the cam gear pin,
and a movable chassis that is provided with a reel and moves linearly in the loading and unloading states, and stops in the stop and play states, and a first spring supported by the movable chassis is attached to one end of the movable chassis. The end is biased in the direction of the reel, supported rotatably around a fulcrum provided on the movable chassis against the force of the first spring, and biased by the fulcrum in a direction opposite to the reel. and a second spring set to be weaker than the force of the first spring, a lower arm having a groove at the other end, and a protrusion at one end for locking the reel. , and a pin that loosely fits into the groove of the lower arm is provided on the lower surface of the one end, the second spring is attached to the one end, and the second spring is attached to the lower arm around a fulcrum provided at the other end of the lower arm. an upper arm that is rotatably supported against the second spring and has a pushing part on the other end against which the cam gear pin is pressed; The protrusion of the upper arm is moved away from the reel by a spring, and in the stopped state, the cam gear pin pushes the pushing part of the upper arm, so that the upper arm is moved by the force of the second spring. The protrusion rotates against the reel and locks the reel, and in the play state, the cam gear pin further pushes the upper arm, and the pushing force is applied to the lower arm via the pin of the upper arm. a reel lock configured such that the lower arm rotates in a direction opposite to the reel through a fulcrum against the force of the first spring, and the protrusion of the upper arm moves away from the reel; mechanism.
