<p><P>PROBLEM TO BE SOLVED: To provide a game machine which allows a player to highly flexibly adjust sound volume. <P>SOLUTION: In a general control ROM, loudness indicated by a sound volume signal to be output to a speaker is stored as a sound volume value. On a general control board, a turning type sound volume adjusting knob is arranged. By turning the sound volume adjusting knob, the loudness (sound volume) output from the speaker can be adjusted in multiple stages. A general control CPU can select one sound volume value from the sound volume values stored in the general control ROM on the basis of the operation of the sound volume adjusting knob and a second operation button. The range of the sound volume value changeable by the second operation button is constituted to be set in a wider range than the range of the sound volume value changeable by the sound volume adjusting knob. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
