PURPOSE:To operate the system smoothly and improve the reliability, by providing a position detector and a fixed pattern signal generator in a package card to detect the mounting state of the stored package card. CONSTITUTION:A central control device 1 reports storage positions of mounted package cards 7 to a position information transmitter 5 provided in a searching device 2 and transmits storage position signals to card classification detection bus 12. Signals are identified by position detectors 3 provided in respective cards 7, and peculiar pattern signals are transmitted from pattern signal gennerators 4 to the card classification detection bus 12 and are read by a pattern signal detector 6 and are reported to the central control device 1. The central control device 1 compares these reported signals with data indicating classifications of package cards in storage positions; and if they are different from each other, storage positions, card classifications, etc. are outputted to an input/output control device and are transmitted to the maintenancer. |
