PURPOSE:To enable to feed a disk intermittently when a driving lever is turned an angle greater than a prescribed value even if the turning angle of swing angle of the driving lever is not even, by employing such an arrangement that the disk is locked or set free depending on the position of a restriction lever of an intermittent turning apparatus. CONSTITUTION:When a driving lever 8 is turned to the right while keeping engagement of a feed pawl 11 and an internal tooth 7 and a disk 5 is turned one pitch in the counterclockwise direction after a push member 19 has passed through a work cam 17, an engaging member 27 drops into the next internal tooth 7 and a restriction lever 13 is returned from its upper position to a lower position. Then, the feed pawl 11 of a feed lever 10 comes out of engagement with the internal tooth 7 and the driving lever 8 continues its rightward swing motion. However, the feed pawl 11 is moved while simply opposing the inner peripheral surface of the disk 5. Therefore, the disk 5 can be moved at the steps of one pitch positively each time the driving lever 8 is turned reciprocally. |
