Patent ID: 8091777

Claim:
A monitoring apparatus for monitoring an open/close status of open/close portions of multiple money processing machines, comprising: an open/close detection unit which detects the open/close status of the open/close portion of each of the multiple money processing machines and which comprises: an RFID inlet which stores individually different ID information, which transmits radio waves and which is attached to each of the multiple money processing machines behind the open/close portion; and an RFID reader which detects the radio waves transmitted from the RFID inlet via the open/close portion only if the open/close portion is opened and which is independently provided outside the money processing machine; an operation status monitoring system monitoring an operation status of each of the multiple money processing machines; and an alarm output unit which outputs an alarm signal if the open/close detection unit detects that the open/close portion is opened based on the radio waves and if the operation status monitoring system determines that the money processing machine is not operating, wherein the operation status monitoring system successively transmits a first signal to each of the money processing machines in a predetermined interval, and the operation status monitoring system determines an operation state of each of the money processing machines based on whether or not a second signal transmitted from the money processing machine in response to the first signal is detected.
