<p>PROBLEM TO BE SOLVED: To provide a game machine, when a bus is occupied by group unit control means, capable of releasing the bus.SOLUTION: The game machine includes: group unit control means that are provided in respective groups formed by dividing a system of a performance device a plurality of groups; and group integrated control means that integrally controlling the group unit control means. Intervals between the group integrated control means and the group unit control means are connected by timing signal lines and data signal lines so as to enable data transmission. The group integrated control means has first transmission means for transmitting outgoing data, and occupation determination means for determining whether the data signal lines are occupied or not. The group unit control means has validation setup means of initialization means for initializing itself, a second transmission means to which a common address and an individual address are preliminarily allocated and that outputs incoming data, and common address invalidation setup means for invalidating the common address.</p> |
