Therefore, when the customer wants to rent a specific disk, he takes out the storage case from the display case and submits it to the store clerk to perform the necessary rental procedure.

[0003] In order to prevent the rental disk from being stolen, various measures have conventionally been taken.

[0004]

As one countermeasure for preventing theft, the present applicant has previously locked a disk with a locking device in a state of being stored in a storage case, and has an unlocking key held by a clerk. A technique has been proposed in which a disk can be detached from a storage case only by using the disk alone (Japanese Patent Laid-Open No. 9-3014).
No. 68). However, this prior art is configured to perform locking and unlocking with the lid of the storage case opened,
The locking and unlocking work of the clerk is complicated. That is, the clerk
At the time of lending, three steps of opening the lid, unlocking, and closing the lid are required. Similarly, at the time of return, a three-step operation of opening the lid, locking the door, and closing the lid is required, and thereafter, it is stored in a display case and displayed. Even more, even if the disk is locked, the lid itself can be opened and closed, so it is possible for a customer visiting for theft to open the lid and attempt to unlock it.

According to this known technique, if a visitor attempts to take a disk storage case out of a store without going through a lending procedure, a tag is detected at an entrance / exit gate of the store and a warning is issued. The system includes an electromagnetic detection type and a radio wave detection type. In addition, the tag attached to the case has an erasing method and a security bag method, and in the former case, the customer who has received the lending procedure deletes the tag detecting means by the clerk, and In the case of, the tag is insulated by putting the storage case in the security bag, so that no alarm is issued when passing through the entrance gate. However, a visitor destined for theft removes the tag from the case and takes it out of the store. For this reason, conventionally, tags have been attached to the case so that they cannot be removed.
There is a problem in that the tag itself, a part of the case, and a stored disk are damaged when the tag is forcibly peeled off.

For this reason, the present invention provides a disk storage case so that the theft detection tag is not visible from the outside.
Moreover, an object of the present invention is to provide an anti-theft device provided so as to make removal completely impossible.

[0008]

Therefore, the present invention is configured as a first means in a configuration in which a theft detection tag is attached to a part of a disk storage case.
