Abstract: ID readers 22 are provided on both left and right sides of a hoisting frame of a stacker crane in an automated warehouse for reading an ID tag 44 of a container 40. ID readers 24 are provided above the hoisting frame 24 for reading ID tags 48 of individual goods 46 on the container 40. When the container 40 is pulled onto the hoisting frame 8 by a slide fork 10, the ID tags 48 of the individual goods 46 are read. It is possible to read an ID of the container and IDs of the individual goods simply and reliably, and an inventory check or the like can be performed on the hoisting frame.
