PURPOSE:To restrain discharging of the battery to make the operation of the load possible, by preventing the power source current from being flowed to the central information processing device when the ignition switch is opened, in the moving material internal wiring system using the optical signal. CONSTITUTION:Light switch 12 or the like which can operate independently of ignition switch 11 operates switch 92 through gate circuit 8 without intervention of central information processing device 2 to drive terminal information device 4 and load 5. Since central information processing device 2 is connected to power source 6 through ignition switch 11 or switch 91 operated together with ignition switch 11, power is not fed to central information processing device 2 unless ignition switch 11 is turned on. Though power is fed to gate circuit 8 independently of ignition switch 11, several milliamperes are sufficient in the ordinary motorcar for riding for limited loads such as the light. |
