  • Radio audio/facsimile communication device
    Patent number: 4922546
    Abstract: A radio facsimile interface unit is connected between a radio set provided with a speaker and a facsimile machine and also connected to a microphone stand provided with a microphone and a manually operable transmission switch. The interface unit is so structured to allow the radio set to carry out an ordinary audio communication using the speaker and the microphone. The radio set is normally set in a reception mode and the transmission switch is depressed only when audio information is to be transmitted. The interface unit is provided with a relay between the microphone and the radio set and the relay is disconnected when the facsimile is in a transmission mode, so that facsimile communication is given a higher priority than audio communication.
