<P>PROBLEM TO BE SOLVED: To reduce the number of components by a novel switch having both a sound volume adjusting function and a game mode setting function. <P>SOLUTION: A setting area of an operating part includes a plurality of output sound volume setting areas. The output sound volume setting areas are associated with different game modes (normal mode and power-saving mode), respectively, thereby providing a single switch with both the sound volume adjusting function and the game mode setting function. <P>COPYRIGHT: (C)2013,JPO&INPIT |
