Claims (9)

A gaming machine in which an electronic tag including a storage unit storing unique identification information and an antenna unit that transmits a radio wave including the identification information is attached to a control device that controls the game,
Comprising reader means for reading the identification information by receiving the radio wave;
A gaming machine, wherein the reader means is arranged in a radio wave arrival area where radio waves of a level at which the identification information can be read reach. The reader means includes a call wave transmitting means for transmitting a call wave for calling the identification information, and a response wave receiving means for receiving a response wave from the electronic tag for the call wave,
Furthermore, response period measuring means for measuring a response period from when the call wave is transmitted until the response wave is received;
A determination unit that compares a reference response period set in advance with a response period measured by the response period measurement unit, and determines whether the measured response period is normal based on the comparison result;
The gaming machine according to claim 1, further comprising: an abnormal process executing unit that executes an abnormal process when it is determined by the determining unit that the measured response period is not normal. A fraud monitoring system comprising the gaming machine according to claim 1,
The reader means includes a call wave transmitting means for transmitting a call wave for calling the identification information, and a response wave receiving means for receiving a response wave from the electronic tag for the call wave,
Furthermore, response period measuring means for measuring a response period from when the call wave is transmitted until the response wave is received;
A determination unit that compares a reference response period set in advance with the response period measured by the response period measurement unit, and determines whether or not the measured response period is normal based on the comparison result;
A fraud monitoring system comprising: an abnormal process executing unit configured to execute an abnormal process when the determination unit determines that the measured response period is not normal. A gaming machine in which an electronic tag including a storage unit storing unique identification information and an antenna unit that transmits a radio wave including the identification information is attached to a control device that controls the game,
When the identification information is read, the reader device that reads the identification information by receiving the radio wave is used to position the reader device in a radio wave arrival area where a radio wave of a level at which the identification information can be read reaches. A gaming machine comprising a positioning means. The gaming machine according to claim 4, wherein the positioning means is a reader device contact portion provided so as to face the electronic tag. The reader device abutting portion is formed of a material that can transmit the radio wave, and an end of the reader device on the side of the radio wave receiving portion is abutted on the side opposite to the side facing the electronic tag The gaming machine according to claim 5, which is formed. A base body rotatably attached to the front of the gaming machine with respect to the attachment object, and the control device is disposed on the back of the base body;
7. The radio wave arrival area is set on the rotating tip side on the back surface of the base body, and the positioning means is provided on the rotating tip side on the back surface of the base body. A gaming machine according to claim 1. 8. The positioning device according to claim 4, wherein the positioning unit defines the position of the reader device so that a distance between the receiving unit that receives the radio wave in the reader device and the electronic tag is always constant. The gaming machine according to any one of the above. A fraud monitoring system comprising the gaming machine according to any one of claims 4 to 8,
The reader device includes a call wave transmitting means for transmitting a call wave for calling the identification information, and a response wave receiving means for receiving a response wave from the electronic tag for the call wave,
Furthermore, response period measuring means for measuring a response period from when the call wave is transmitted until the response wave is received;
A determination unit that compares a reference response period set in advance with the response period measured by the response period measurement unit, and determines whether or not the measured response period is normal based on the comparison result;
A fraud monitoring system comprising: an abnormal process executing unit configured to execute an abnormal process when the determination unit determines that the measured response period is not normal.
