<P>PROBLEM TO BE SOLVED: To provide a game machine for simply controlling volume in a game machine to control volume by rotary-operating an operation part. <P>SOLUTION: The game machine includes: a sound output means for outputting arbitrary sound; a volume control means which has an rotary-operable operation part and controls output volume of the sound output means in accordance with an operation position when the operation part is rotary-operated; and a sound output control means for setting output volume of the sound output means in accordance with the operation position of the operation part of the volume control means and controlling sound output from the sound output means. In the game machine, when an operation position of the operation part of the volume control means is changed, operation sound showing the fact that the volume control means has been rotary-operated is output by the sound output means in volume corresponding to the operation position of the operation part of the volume control means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
