PURPOSE: To control lightup and extinction of illuminations during traveling service simply and allow a single wireless operating unit to have switching function for a plurality of places by comparing a self receiver number set for each receiver with the receiver No. data contained by received signal, delivering a transmission signal to a main operation board in case the two are identical, and making on/off control of the lighting fixture in conformity to command of the wireless unit.

CONSTITUTION: When a person in traveling service selects a receiver No. with a receiver No. selection switch 501 on a wireless operating unit specifically devoted to traveling service 5 at the entrance to a certain room and puts on an ON switch 504, the wireless unit 5 emits a signal containing receiver No. and information that the ON switch is turned on. This emitted signal is received by an entrance receiver 6 installed near the entrance to an illumination facility. Upon receiving it, this entrance receiver 6 judges that the self receiver No. is identical to the receiver No. in the received signal. When they are identical, the receiver 6 gives the main operation board 1 a transmission signal indicating illumination-ON from the wireless unit 5. According to this transmission signal the main operation board 1 delivers a control signal to a specified terminal unit 2 so as to light up the specified load 4.
