[0017]

According to the present invention, since the package carrying-in plate for the package supporting plate in the warehouse is outside the package passage, and the package discharging on the supporting plate is also performed by the fixed cam plate, the pusher is used. It is possible to store a large number of packages without the need to install the above in the warehouse and to leave no wasted space in the warehouse.

Further, at the package unloading port, since the package is rolled and ejected only by driving the chain, a drive mechanism for taking out the package is not required, and complicated control control is also unnecessary. . Further, even when different types of packages are stored, it is possible to take out only desired packages by circulating the chain, and there is an advantage that the equipment is inexpensive because of the simple structure.
