Abstract
A wireless data input device requiring no cable for connection to the keyboard or to the pointing device. A wireless keyboard 16 incorporating a pointing device has a data encoder 21 and an RF transmitter 22, and transmits the key data and the pointing cursor data to the reception unit 3 which is connected to a keyboard connector 6 and to a mouse connector 7 of a computer 1 through connection cables 8 and 9. The reception unit 3 has a data decoder 11 and an input/output control unit 12, and decodes the received data and inputs them to the computer through bidirectional communication.
