<p>PURPOSE:To prevent the accident and clinch of each part of a device by the inertia of a motor and driving each part by abutting a pair of the arm members rotatable co-axially with a gear to the right and left parts of the projecting piece provided on the pin sliding inside a guide hole and the gear with projection, and loading an energizing member between a pair of the arm bodies. CONSTITUTION:A pair of arm bodies 19, 20 are loosely fitted rotatably on a shaft 18, the projecting piece 9a of a buffer gear 9 is located between the arms 19a, 20a and both ends of the spring 11 wound on a boss 9b are locked to the arm bodies 19, 20. Three pins 13b-13d are respectively planted at the right and left both sides on a container 13 and inserted slidably into the guide holes 1a-1c of a stationary chassis 1 respectively. The pin 13c reaches the terminal of the guide hole 1b and further movement is made impossible but with the spring 11 being extended in the reverse direction to its energizing direction, the force accompanied by the rotation of a motor is made to release. The clinching state and the breakdown of each part are thus prevented.</p> |
