<P>PROBLEM TO BE SOLVED: To provide a slot machine preventing fraudulence such as falsification of a command transmitted from a main control board to a subordinate board by monitoring the presence of consistency in processing between the main control board and the subordinate control board. <P>SOLUTION: The slot machine (10) includes the main control board (100) for controlling the progress of the play, and the subordinate board (200) for controlling a performance of the play. At least stopping operation signals from stop switches (56L, 56C and 56R) are input to the main board and the subordinate board. The main control board transmits a command with various coded information, and the subordinate board executes an AT lottery and the performance according to the received command. A consistency discrimination means (651) of the subordinate control board independently determines a display mode of symbols based on an excitation data signal to drive reels, a reference position signal and stopping operation signals from the stop switches, and discriminates the consistency of the display mode with information on the stopping position of the reels specified by a stopping position data command. <P>COPYRIGHT: (C)2013,JPO&INPIT |
