<P>PROBLEM TO BE SOLVED: To prevent output volume from changing from maximum volume to minimum volume in a game machine provided with a volume control switch, rotary operation of which is performed. <P>SOLUTION: In the game machine for controlling output volume of a sound output means in accordance with an operation position when an operation part of the volume control means is rotary-operated, at an operation position of the operation part of the volume control means, a minimum volume position corresponding to the minimum volume output by the sound output means and a maximum volume position corresponding to the maximum volume output by the sound output means are arranged to be adjacent to each other, and when the operation part of the volume control means is rotary-operated unidirectionally from the minimum volume position to the maximum volume position, output volume of the sound output means is increased, and when the minimum volume position is reached as a result of unidirectional rotary operation of the operation part of the volume control means from the maximum volume position, the output volume of the sound output means is not changed into the minimum volume. <P>COPYRIGHT: (C)2013,JPO&INPIT |
