And
The dimming control unit 5b controls the variable resistor 13 to change the resistance value, thereby adjusting the current flowing through the light emitting diode 12 and adjusting the light emission amount of the light emitting diode 12. In the example shown in FIG. 3 (b), an NPN in which the code signal from the control means 5 is input to the base
The light emitting diode 12 is connected between the collector of the switching transistor 11 and the collector of the current amplification transistor 23 of the PNP to which the current control signal from the dimming control unit 5b is input. Then, the dimming control unit 5b controls the current of the current amplifying transistor 23 to adjust the current flowing through the light emitting diode 12 and adjust the light emission amount of the light emitting diode 12.

A button and a dimming control unit for controlling the dimming unit corresponding to the output setting button are provided in the control unit, so that a user operates the output setting button and emits light of the light emitting unit. By setting the dimming control, the dimming control unit can dimming the dimming means in accordance with the set light emission amount. Therefore, even in a relatively small room, even if the optical signal is weak, the dimming control unit can be sufficiently covered. When light can be received by the operation device, the amount of light emission can be reduced, the current consumption of the battery used as the power source can be reduced, and the life of the battery can be prolonged. On the other hand, in a relatively large room or in a state of the room, if the light cannot be received on the operated device side unless the optical signal is strengthened, the operability can be improved by increasing the light emission amount.
