A storage shelf 4 is provided which has, for example, two rotatable mounts 18, 19. A notch 41 is formed in the mount 18 so that a cassette 34 can be freely transferred between the lower mount 19 and an overhead travelling carriage 8. ID readers 6 are provided on poles 16, 17 of the mounts 18, 19, respectively. Thus, the ID 36 of the cassette is read and memorized in a storage shelf file 13. The IDs of stored articles can be managed, resulting in advanced operations. |
