<P>PROBLEM TO BE SOLVED: To provide a Pachinko game machine which can detect fraudulent act using a game ball attached with a thread. <P>SOLUTION: The Pachinko game machine 1 includes: a fraudulent act-detecting unit 87 (a pivoting member 61 and a photosensor 85) which operates by a load of the game ball through the thread S (a linear member), the unit 87 being prepared on a game ball passage 58 (a game ball passage from a game ball receiving tray 6 to a playfield 3); and a determining unit (a main control board 20) which determines that the game ball attached with the thread S is shot to the playfield 3 based on the operation of the fraudulent act-detecting unit 87. In the fraudulent act in which the game ball attached with the thread S is shot to the playfield 3 and the game ball is guided to a winning pocket by operating the thread S, the load of the game ball is applied to the pivoting member 61 arranged on the game ball passage 58 through the thread S when the game ball is falling down thereby causing the fraudulent act-detecting unit 87 to operate. Thus, the fraudulent act using the game ball attached with the thread S can be detected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
