PURPOSE:To move freely a plurality of terminal devices in radio transmission space, by transmitting information such as instructions and data of the terminal devices and a terminal controller in radio electromagnetic waves. CONSTITUTION:The terminal controller 1 transmits the content of data after converting it into radio electromagnetic waves F1, when the instruction given from a central processing unit is edited into a concrete instruction an transmitted to a transmitter/receiver 2 in the form of serial data to execute the instruction. The electromagnetic waves are received at antennas 13, 23, fetched to terminals 10, 20, where demodulation and analysis are performed and when the instruction is for each terminal, it is executed. When data to the controller 1 is transferred, the content is converted into radio electromagnetic waves F10, F20, which are transmitted to the device 2 of the controller 1. |
