<P>PROBLEM TO BE SOLVED: To solve a problem in a conventional pinball game machine wherein an illegal act is performed because the processing cycle of a CPU is recognized from the driving cycle of a driven device recognizable by a player. <P>SOLUTION: Driven devices such as a normal symbol display device 11, a special symbol display device 12, a state display device 15, a normal electric generator 17 and a large prize hole 18 are driven by an output driving circuit 38 outputting drive signals based on drive data held in a data latching circuit 39 synchronously with a specific cycle of 8 [msec] by the input of a dividing clock signal from a dividing circuit 41. Consequently, an output cycle of drive data output in a predetermined cycle of 2 [msec] from a data output means by the control of a main CPU 32 differs from the output cycle of drive signals output in the specific cycle of 8 [msec] from the output driving circuit 38, and the player cannot recognize the control processing cycle of the main CPU 32 from the recognizable operation cycle of the driven device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
