<P>PROBLEM TO BE SOLVED: To provide a transmitter/receiver capable of attaining both high-speed communication responsiveness and low power consumption in accordance with the existence of a plurality of communicable devices when the plurality of devices exist within the same area to be able to communicate. <P>SOLUTION: This transmitter 1 generates transmission data composed of frames in a prescribed format, transmits the transmission data by radio and when generating the transmission data, varies the transfer amount of a bit synchronizing signal being a header of the frames as necessary. This receiver 2 intermittently receives the transmission data from the transmitter 1, and when the transfer amount of the bit synchronizing signal is varied as necessary on the basis of the received transmission data, the receiver 2 varies the cycle of intermittently receiving the next transmission data in accordance with the varied transfer amount. <P>COPYRIGHT: (C)2007,JPO&INPIT |
