It is energized in the direction of contact with. Next, the operation of this embodiment will be explained.

As shown in FIG. 1, the movable body 19 is waiting at an intermediate position where the article pushing unit 24 faces a position for pushing out the lowest article of the articles 3 stacked on the front leg of the storage frame 1. (
Figure 7a).

In this state, the electric motor 18 that rotates the cam body 11 located below the storage frame 1 of the article 3 selected by the article dispensing signal is driven, and the cam body 11 is rotated in one direction.

Due to this rotation of the cam body 11, the moving body 19 whose slider 22 is engaged with the spiral groove 15 is rotated in the direction of rotation of the cam body 11 because the article pushing part 24 is engaged with the innermost hole 8 of the guide groove 7. (Fig. 7a), and the article 3 is placed in the storage frame 1.
The article is discharged from the article outlet 4. In this state, moving object 1
The position of the notch 9 at the front end of the article extrusion section 24 is reached, and the movable body 19 is allowed to be displaced in the rotational direction of the cam body 11.

At this time, the movable body 19 is pressed against the contact 29 of the stopper 27 by the spring 30', and due to the contact friction with the contact 29, the movable body 19 is rotated together with the cam body 11.
When the article extrusion section 24 that has passed through the notch 9 rotates approximately 270 degrees, it comes into contact with the lower surface of the substrate 6, and the rotation of the movable body 19 is stopped. At this time, the slider 22 of the movable body 19 is connected, for example, from the right helical groove part 12 of the helical groove 15 to the left helical groove part 13 via the connection groove part 14, and the movable body 19 moves the article extrusion part 24 by the rotation of the cam body 11. It is moved rearward along the lower surface of the substrate 6. When the movable body 19 reaches the intermediate position, the detector 25 stops the electric motor 18, and the movable body 19 is stopped (FIG. 7b). Further, when the lowest article of the storage frame 1 is taken out, the next article 3 is supported on the base plate 6 and is made to face the article exit 4.
