Locking system, playing machine, and device management system
First Claim
1. A locking system comprising an IC tag for locking operation, an IC tag monitoring device that makes communication with the IC tag for locking operation, and a locking device that locks and unlocks a device based on a result of monitoring made by the IC tag monitoring device, wherein said IC tag for locking operation stores identification data that is used for distinguishing the IC tag from other IC tags, wherein said IC tag monitoring device includes first transmission means for transmitting a calling wave for calling said IC tag for locking operation, first reception means for receiving a reflected wave returned from said IC tag for locking operation, an antenna for key that is connected to said first transmission means and said first reception means, key determination means for determining as being normal if said first reception means receives a reflected wave containing identification data identical to registered data that is registered beforehand within a specified period of time since said first transmission means transmits a calling wave, and first output means for outputting the result of key determination made by the key determination means to the outside, and wherein said locking device comprises a key including said IC tag for locking operation and a lock that includes said antenna for key and into which said key is to be inserted.

Abstract
An IC tag for monitoring opening/closing operation 86 is attached on the backside of the glass frame 111 at its upper right portion, and on a main body frame 110 opposing to the glass frame 111, an antenna for monitoring 68 is attached. An IC tag for monitoring opening/closing operation 186 is attached on the inside of the right frame of the wooden frame 112, and on the main body frame 111 opposing to the wooden frame 112, an antenna for monitoring 168 is attached. The distance between these antenna and IC tags is respectively set to about 3 mm in a state where the frames on which they are provided are closed. A R/W unit always polls the IC tags via the antennas. 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, the communication becomes unavailable and this state is immediately detected. An antenna for key 128 is buried above a keyhole 120. When a key incorporating an IC tag for key therein is inserted in the keyhole 120, the R/W unit reads the ID code of the IC tag. A solenoid for locking operation is turned on only when the read ID code is identical to the registered ID so as to pull a plunger for unlocking the frame.

8. A locking system comprising an IC tag for locking operation, an IC tag for monitoring opening/closing operation, an IC tag monitoring device that makes communication with said IC tag for locking operation and said IC tag for monitoring opening/closing operation, and a locking device that locks and unlocks a device based on a result of monitoring made by the IC tag monitoring device, wherein said IC tag for locking operationtores identification data that is used for distinguishing the IC tag from other IC tags, wherein said IC tag for monitoring opening/closing operation stores identification data that is used for distinguishing the IC tag from other IC tags, and is provided to an opening/closing member that is opened and closed from the device or to a device main body in the vicinity of the opening/closing member, wherein said IC tag monitoring device includes transmission means for transmitting a calling wave for calling said IC tag for locking operation or said IC tag for monitoring opening/closing operation, reception means for receiving a reflected wave returned from said IC tag for locking operation or said IC tag for monitoring opening/closing operation, an antenna that is connected to said transmission means and said reception means, determination means for determining as being abnormal if said reception means does not receive a reflected wave containing identification data identical to registered data that is registered beforehand within a specified period of time since said transmission means transmits a calling wave to the IC tag for monitoring opening/closing operation and if said reception means does not receive a reflected wave containing identification data identical to registered data that is registered beforehand within a specified period of time since said transmission means transmits a calling wave to said IC tag for locking operation, and output means for outputting the result of determination made by said determination means to the outside, and wherein said locking device comprises a key including said IC tag for locking operation and a lock that includes said antenna and into which said key is to be inserted.
