Claims

[Scope of utility model registration request]

A driving pulley is provided on the output shaft of the motor, a driven pulley is placed at an appropriate distance from this pulley, and a belt suspended between the two is connected to a table to drive the table back and forth as the motor rotates forward and backward. In addition, in a table drive device that reciprocates the position of the table by making both ends of the table abut against stoppers, a drive pulley is loosely fitted to the output shaft of the motor, and a fixed shoe that clamps both end surfaces of the pulley is provided. A table characterized in that a movable shoe is arranged on the outer periphery of the output shaft, and a spring is interposed between the movable shoe and the tip of the output shaft so that the movable shoe is constantly pressed against the end face of the pulley and fixed to the output shaft. Drive device.
