In this state, the lifting mechanism 34 separates from the storage frame and descends. On the descending passage side, when the descending mechanism 35 starts to descend, the support protrusions 11, 1" automatically engage the support hooking holes 16, 16" of the next stage storage frame 13, and then engage the descending mechanism 35. When only the storage frame 13 that is in the
6" can be removed from the lifting hook holes 17, 17".

The storage frame 13 of the forward passage 5 and the storage frame 13 of the backward passage 6 are moved in opposite directions by hooks 29 for lateral movement of the forward and backward movement mechanisms 24, 24'' hooking into the latching holes 18 for lateral movement of the storage frame 13. Migrate.

The above sequence is repeated to store or take out the required object.

As mentioned above, the present application provides a space for two storage frames to be placed in the circulation passage consisting of an ascending passage, a descending passage, a forward passage, and a retreat passage within the enclosure frame, and then makes full use of the entire space. As a result, space utilization is extremely efficient, and circulation movement by the support mechanism, lifting mechanism, lowering mechanism, and back and forth movement mechanism can be performed smoothly.

In addition, it has a wide range of applications, including automation of product stock in automated factories, household cupboards, bookshelves, and display shelves.

Furthermore, the longitudinal movement mechanism, the raising mechanism, and the lowering mechanism are driven by movement of drive wires by a crank drive mechanism, which is the same driving source, so that they are both inexpensive and compact.
