<P>PROBLEM TO BE SOLVED: To reduce electric power consumption in a game machine. <P>SOLUTION: The electric power consumption for illumination is reduced while a game is not executed for a certain period of time. A command to be transmitted without exception from a main board to a subordinate board during the game is monitored, and the mode of the game machine is shifted to a power-saving mode if the command is not transmitted for a certain period of time. In the power-saving mode, part of light emitting devices for illumination is turned off. If at least two of light emitting devices of three kinds, red, green and blue are lighted, luminance information is changed so that only one of them is lighted. This change is executed based on a prescribed regulation (table) not to cause disorder before and after the change. <P>COPYRIGHT: (C)2013,JPO&INPIT |
