PROBLEM TO BE SOLVED: To provide a remote commander and a voice support device that automatically interrupts power to a voice reception circuit and a voice amplifier circuit so as to prevent useless power consumption. SOLUTION: The remote commander 1 is provided with a reception circuit 4 that receives a voice signal of a television monitor 11, an operation button 6 that controls ON/OFF of a power of the television monitor 11. A battery 14 is connected to a power terminal (+B) of a remote control circuit 3 and connected to a relay circuit 15. The relay circuit 15 is provided with a relay contact 15b and the battery 14 is connected to a voice amplifier 12 and the power terminal (+B) of the reception circuit 4 via the relay contact 15b. When a power switch 16 connected in parallel with the relay contact 15b is closed, power is supplied to the voice amplifier 12 and the reception circuit 4 from the battery 14. A caption 17 is a switching transistor(TR) that applies ON/OFF control to a current flowing through a relay coil 15a of the relay circuit 15. |
