摘要

PPROBLEM TO BE SOLVED: To replace a model of a game machine set in a game parlor with a new model without adding change in the hardware to the game machine or to a fraudulence monitor device only by changing the software, and to centrally monitor the fraudulence. PSOLUTION: The game machine 2, the fraudulence monitor device 1 and a primary synthetic monitor device 8 are set in the game parlor, and a secondary synthetic monitor device 303 and a system management device 305 are connected via a network. The fraudulence monitor device 1 and the game machine 2 are connected in the electrically non-contact state by a sensor 3. The system management device 305 transmits a normal operation pattern of the game machine 2 to the fraudulence monitor device 1 and the pattern is stored in the fraudulence monitor device 1. The fraudulence monitor device 1 compares the operation pattern based on an input signal from the sensor 3 and the previously stored normal operation pattern and determines an abnormal state of the game machine 2. The fraudulence monitor device 1 monitors the fraudulence to the game machine 2 from outside in this way. PCOPYRIGHT: (C)2006,JPO&NCIPI
