<P>PROBLEM TO BE SOLVED: To provide a game machine with a time information acquisition unit that facilitates maintenance and inspection by specifying a time at which a harness or a connector connecting between a main control board and other board is disconnected or comes off. <P>SOLUTION: A power supply board 851 is equipped with a detection circuit power supply 851h, a RTC control section 4190 is arranged on a peripheral control board 4140, and the detection circuit power supply 851h is connected to the RTC control section 4190 via a main control board 4140. Even when interrupting the power supply, the RTC control section 4190 can detect, by a capacitor BC2, that the main control board 4140 is removed. A diode (not illustrated) for preventing backflow when interrupting the power supply, is prepared between the capacitor BC2 and the detection circuit power supply 851h. Here, the time interrupting the power supply unit is a case that a power supply of the game machine is interrupted and thereby an output of the detection circuit power supply 851h becomes zero. <P>COPYRIGHT: (C)2012,JPO&INPIT |
