The above is a description of the operation of uniform spreading, but FIG.
In the case of the non-uniform spreading shown in (1), the non-uniform spreading can be performed by setting the set time of the spread space forming timer between the shelves to a transition time that becomes non-uniform in advance. Since the operation flow in that case is the same as that in FIG. 11, description thereof will be omitted.

As described above with reference to the embodiments, according to the present invention, the movable shelves are configured so that they can be spread and densely packed to increase the storage density in a narrow space, and the dispensing operation is quick and easy. It is a moving rack device, a structure that saves the number of spreading space forming timers, a structure that can independently set the forming width of the spreading space, and a passage selection / blocking operation device that has functions of passage selection operation and passage blocking operation. In combination with the above, when the desired passage is selected or when the shelf is not used, the passage entrance operation between the shelves is blocked and the passage is shut off after the passage is shut off. It is possible to achieve a better air conditioning effect for the stored items while ensuring the safety of the space between them. Further, even if a semiconductor circuit or a sequencer is used instead of the relay circuit of this embodiment, the same effect can be obtained by using a spread space forming timer for each passage.
