Abstract

PROBLEM TO BE SOLVED: To reduce restrictions on an installation place and to add a two-way data transfer function between devices by implementing a wireless transmitting and receiving function by making use of a radio communication. SOLUTION: When the wireless keyboard device is in operation, information is inputted from a keyboard part 101 as an information input means. The inputted data are processed by an information input processing part 305 and converted into a digital signal, which is transmitted to a signal processing part 301. The signal is processed by the signal processing part 301 and when a signal control means 306 judges that the signal is necessary, the signal is transmitted to a wireless transmission and reception part 300 and transmitted from the wireless transmission and reception part 300 to equipment as a host, e.g. a computer 120 by the control judgement of the signal control means 306 according to the standard of a protocol used for a radio communication. The computer 120 receives the signal by an internal or externally-connected wireless transmission and reception part 121 and receives and confirms the transmission data according to the protocol standard.
