Abstract: A storage case comprising a case body having two or more storage parts into which CDs or recorded cassettes are inserted respectively, sensors detecting said CDs or said video cassettes taken out from said storage parts, a counter integrated by signals from these sensors, and an indicator part indicating an integrated value from this counter. This structure enables said storage itself to manage the rental of said CDs or said video cassettes, which leads to a very easy confirmation of the rental volumes without using conventional technical know-hows such as unopened seal or the likes.
