PROBLEM TO BE SOLVED: To read storage content information stored in a tag in a short time.SOLUTION: A library system 100 is formed of an information collection device 30 having a directional antenna 14 for emitting the predetermined electric wave, a management part 24, antenna moving means for moving the antenna 14 to a plurality of predetermined positions in response to first and second control signals from the management part 24, and antenna direction changing means for changing a direction of the antenna 14 within the predetermined angle; and a storage device 10 having a plurality of slots 13. Each of the plurality of slots 13 can be inserted respectively with a storage container 16 for storing a storage medium 11 which stores the storage content information for specifying the content stored in the storage medium 11 and having the tug 12 for emitting the electric wave including the storage content information stored at the time of receiving the predetermined electric wave from the antenna 14. The antenna 14 receives the electric wave emitted by the tug 12 and transmits the storage content information included in the electric wave to the management part 24.SELECTED DRAWING: Figure 1 |
