PROBLEM TO BE SOLVED: To eliminate the need for a high place work accompanied by danger even when contents of voice information are revised and reproduced by configuring the device with a remote controller and a voice notice device main body operated by remote control of the remote controller. SOLUTION: A recording operation signal is generated by pressing a recording key of a remote controller 45. An infrared ray transmission section 36 modulates a recording operation signal into a pulse code signal and allows an infrared ray LED 34 to emit a resulting infrared ray, which is received by an infrared ray reception section 35 of the voice notice device main body 30. When a control section 42 decodes the pulse code signal to be a recording operation signal, a recording section 19 is set to the recording mode and enters the recording state. A voice signal is given to a recording microphone 46 and a radio transmission section 40 modulates the signal into a prescribed radio frequency and the radio wave is sent from a transmission antenna 41. The radio wave is received by a reception antenna 37 of the voice notice device main body 30 and demodulated into a voice signal by a radio wave reception section 39, recorded on a recording section 19 as voice information and stored in a memory section 20 as voice data. |
