is fixed to the upper end of a rotating shaft 8 which is rotated at a reduced speed by a motor, and is configured to selectively rotate a desired storage box 1 to the opening 2 position via a switch mechanism to be described later.

Reference numeral 9 designates an elevating plate, whose thick corner 9a is screwed onto a screw shaft 10 that is rotated at a reduced speed by a motor, and the opposite corner 9b is provided with a through hole 11, which is inserted into the guide column 12, and the screw shaft 10, the elevating plate 9 is moved up and down through the screw hole 10a. This guide column 12 is provided with an upper limit switch 13 and a lower limit switch 14 facing the lifting plate 9 to regulate the lifting and lowering movement of the lifting plate 9. Normally, the lifting plate 9 is placed at the lower limit switch 14 position. In this case, the bottom of the storage box 1 is slightly spaced apart from the elevating plate 9 to facilitate rotational movement of the storage boxes 1, 1, . . . .

Furthermore, a light emitting section 1 of a photo sensor 15 is provided at the tip of each of the cross-shaped support arms 6a of the rotating frame 6.
5a, a light receiving section 15b is provided below the floor surface, the rotation angle of the rotating frame 6 is regulated, and a desired storage box 1 is aligned with the opening 2.

Reference numeral 8a denotes a cross-shaped handle fixed to the top end of the rotating shaft 8, which is used to manually move the rotating shaft 8 in the event of a power outage. It is also possible to move. For this purpose, a clutch is provided between the rotation shaft 8 and a speed reduction mechanism (not shown).

Next, the support column 1 that loosely supports the aforementioned rotation shaft 8 is shown.
6 has a vertical groove 17 on the outer periphery, and a protrusion 9d of a cylindrical portion 9c formed integrally with the elevating plate 9 is loosely fitted into the vertical groove 17, so that the cylindrical portion 9c moves along the support column 16. The support column 16 is fixed firmly to the base 18 so as not to rotate, and is designed to withstand the weight of the storage boxes 1, 1, . . . .

Figure 2 shows the controller switch and the housing 2.
