PURPOSE:To facilitate adjusting in factory and to ensure safety upon shipment by designating a first mode for turning a power switch OFF and a second mode for holding the state prevailing before interruption when the power supply for electronic machinery is reset. CONSTITUTION:Upon recovery of a power supply circuit 3, a reset circuit 4 produces a pulse for energizing a microcomputor 6. When a power switch is turned ON by means of a remote transmitter 7 through a photodetecting section 8, the microcomputor 6 turns a transistor 11 ON thus closing the switch 10a of a relay 10. When a second mode is designated by means of a remote controller 7 and a jig, the power switch is held in the state prevailing before power interruption by the data stored in an EEPROM 9 and a variety of adjusting is carried out in the production line. The second mode is sustained for a predetermined time by means of a charge/discharge circuit 5. When a first mode is designated by means of the remote controller 7 and a jig prior to shipment, the power switch is not turned ON even upon recovery of power supply. Consequently, production line work can be carried out efficiently. |
