PROBLEM TO BE SOLVED: To transmit an optimum signal, considering influences of a service environment, to improve efficiency and to reduce power consumption by detecting the environmental conditions of a service place of a remote controller such as brightness, and changing the level of an output operation signal from the remote controller in accordance with the detected value of an environment detection element. SOLUTION: A wireless remote controller is operated and an input key identification circuit 15 transfers data corresponding to a key of the remote controller to a register memory 13. A control circuit 12 receives data from the register memory 13 and gives an instruction for measuring the degree of peripheral environment affecting a light signal from LED 6 to an environment condition detection circuit 18. The control circuit 12 turns on a transistor corresponding to environment data sent from the transistors of an LED light emitting circuit 19, controls current flowing in LED 6 and transmits an operation signal corresponding to control data of a depressed key. |
