PROBLEM TO BE SOLVED: To provide a game machine capable of effectively excluding illegal practices which misuse reset operation of a random number generating circuit. SOLUTION: The game machine acquires a random number RND from a random generating circuit to perform lottery processing when prize winning switch signals SWa and SWb are ON in correspondence to operation of a player and generates a beneficial state in favor of the player. The random number generating circuit has: an oscillation circuit 40 for generating a counting clockΦ; counters CTa and CTb for counting the counting clockΦ; counted value holding circuits Ra and Rb for temporarily holding counted value outputs of the counters CTa and CTb when the prize winning switch signals SWa and SWb are ON; and a reset circuit 44 for automatically generating a power source reset signal which indicates a power charge state. The counters CTa and CTb are composed so that they are in a reset state by a power source reset signal RST output by the reset circuit 44. COPYRIGHT: (C)2009,JPO&INPIT
