<P>PROBLEM TO BE SOLVED: To detect a down signal to shift from a power-saving mode to a usual mode quickly, and to exert control to prevent a chance defeat of receiving data. <P>SOLUTION: When network send/receive means (26, 28, and 25) are in the power-saving mode, slave station power-saving control means (27 and 33) shift the network send/receive means (26, 28, and 25) to the usual mode when the down signal is detected by a receiving data detecting means 29, and also the means (27 and 33) store the down signal concerned in a buffer part 30 within a period until shifting to the usual mode concerned is completed, and when the network send/receive means (26, 28, and 25) have completed shifting to the usual mode, the means (27 and 33) exerts control to send out data in the buffer part 30 to an external communication terminal via the network send/receive means (26, 28, and 25). <P>COPYRIGHT: (C)2011,JPO&INPIT |
