A multi-purpose radio transmission/reception (T/R) system includes a radio peripheral (PH200) and a multi-purpose transmission/reception device (H100) for executing one-way radio reception or two-way radio transmission/reception by infrared or RF or ultrasonic. The characteristic of this system is that the radio peripheral (PH200) and multi-purpose transmission/reception device (H100), as required, can be converted to a wired mouse, track ball or touch panel, and may function as a wired mouse, track ball or touch panel in case of insufficient power, power failure, channel interference or radio transmission/reception failure. The device can optionally include multiple interface connectors (or plug-socket units) to connect to each other and to connect both the multi-purpose radio transmission/reception (T/R) system and its matching radio peripheral, or transmission wire for electric energy or both signal and electric energy transmissions: as an option, the radio peripheral (PH200) and multi-purpose transmission/reception device (H100) further can be installed individually or be combined for storage and used separately.
