<p><P>PROBLEM TO BE SOLVED: To provide a Pachinko system that can easily detect the fraudulent act of making dispensed balls put out fraudulently. <P>SOLUTION: The number of remaining units of a prepaid card 200 is calculated by both a prepaid recording medium reader 100 and a put-out control board 60. The put-out control board 60 subtracts the number of remaining units when a dispensed ball put-out operation is completed. Meanwhile, the prepaid recording medium reader 100 subtracts the number of remaining units when a ball bending completion signal EXS output from the put-out control board 60 is changed to a low level from a high level. When the fraudulent act of forcedly keeping the ball bending completion signal EXS at the high level is performed, the number of remaining units calculated by the prepaid recording medium reader 100 does not agree with the number of remaining units calculated by put-out control board 60 because the prepaid recording medium reader 100 cannot subtracts the number of remaining units. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
