PROBLEM TO BE SOLVED: To provide a game machine which enables diverse sound performances without complicating the constitution of a circuit. SOLUTION: This game machine 21 has a sound control board 4 which separately outputs a plurality of kinds of sound signals in accordance with control commands from a main control board 1 for controlling game operation. The sound control board 4 performs processing which comprises: main processing in which an operation including processing (ST6) of conversion from the control command to an Si command is repeated in an infinitely looped manner; and interruption processing which is started by interrupting the main processing forcedly, when a central processing unit (CPU) is in the state of allowing interruption. The interruption processing includes: first processing (TIMERINT) in which the Si command is interpreted for identification of the sound signal to be outputted; and second processing (SNDINT) in which the sound signal identified in the first processing is outputted in each sampling cycle thereof.
