PURPOSE:To get rid of any position slippage due to the recoil of a cam-follower in the time of applying and welding to a stopper by positioning to the position of the other stopper by rotating reversedly after applying and welding the cam-follower to one stopper. CONSTITUTION:The 90 steps rotation of a stepping motor is made, and a cam 3 rotates in the direction of the arrow. Accordingly, wherever a pin 11 may be placed in a cam-groove 4, it is applied and welded to the second stopper 4b. In the case of applying and welding to the second stopper 4b, a driving lever achieves a position of 5b, and the stepping motor steps out. Then, the stepping motor is reversedly rotated by 90 steps. According to the constitution, the driving lever achieves a position of 5c, and the pin 11 is positioned in the position of the first stopper 4a of the inside end of the cam-groove 4. |
