<p><P>PROBLEM TO BE SOLVED: To provide a pachinko game machine capable of avoiding overflow disadvantageous to a player. <P>SOLUTION: In this invention, a first circuit 73 provided with a delay electric circuit 70 for tentatively holding ball detection signals outputted by a special pattern start switch S1 provided in a special pattern start area 20 and outputting the held ball detection signals to a main control board 60 after the lapse of prescribed delay time and a second circuit 74 not provided with the delay electric circuit 70 are interposed so as to be electrically parallel to each other in the connecting line of the special pattern start switch S1 and the main control board 60, and a relay circuit 72 connected to the first circuit 73 and the second circuit 74 for selectively validating one of them is provided. Further, the drive of the relay circuit 70 is controlled so as to validate the first circuit 73 in the case that a special pattern variation holding number U is two or larger and to validate the second circuit 74 in the case that it is less than two. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
