The detent plate 12 is provided with a blocking plate 13 serving as blocking means and a solenoid 14 for driving the blocking plate 13 on the side where the contoured portion P is formed. Here, the blocking plate 13 is allowed to swing about a shaft 15 as a fulcrum. This blocking plate 13 is reciprocated between a blocking position where the detent bin 8 located at the contour part P is prevented from descending and a non-blocking position to prevent the detent bin 8 from leaving the contour part P. The blocking plate 13 is the detent bin 8
This indicates a state in which the fifth
The figure shows a state in which the blocking plate 13 is in a blocking position where it prevents the detent bin 8 from descending.
