Abstract: PROBLEM TO BE SOLVED: To easily attach/detach and move a device by transmitting a connection request packet containing self-identification information in response to the reception of a packet showing connection permission from a first radio equipment, receiving a connection permission packet and setting it through the use of path information in accordance with the reception of the packet which is not reception-designated. SOLUTION: When the reading of data is instructed from a computer 1, a USB controller 33 outputs a USB packet containing necessary data to USB 31 and a USB interface unit B27 receives it. A control unit M25 controls the transmitter of a radio transmitter/receiver B23 so that it transmits the radio packet of an appropriate system. The receiver of a radio transmitter/receiver A21 receiving the radio packet containing data from a device 7 informs a control unit A17 of the reception of data and stores data in a buffer 19.
