LOCKING SYSTEM, PLAYING MACHINE, AND DEVICE MANAGEMENT SYSTEM

Document Type and Number:

WIPO Patent Application WO/2004/018806

Kind Code:

A1

Abstract:

At the rear side of upper right of a glass frame (111), an open/close monitoring IC tag (86) is attached. On the opposing main body frame (110), a monitoring antenna (68) is attached. Inside the right frame of a wooden frame (112), an open/close monitoring IC tag (186) is attached. On the opposing main body frame (110), a monitoring antenna (168) is attached. The distance between the antennas and the IC tags is set to be about 3 mm when the frame is closed and the R/W unit always performs poling of the IC tag via the antenna. When the glass frame (111) or the main body frame (110) is opened and the distance between the antenna and the IC tag exceeds about 5 mm, communication is disabled and the state is immediately detected. Above a key hole (120), a key antenna (128) is buried. When a key having a built-in IC tag is inserted, the R/W unit reads the ID code. If the ID code is a registered ID, the locking solenoid is turned ON and plunger is pulled to unlock.
