<p><P>PROBLEM TO BE SOLVED: To solve the problem that, when noise is superposed on output signals of transmitting parts which do not perform transmission, the noise is superposed on transmission signals to receive incorrect data in the case of a serial communication device configured so that a plurality of transmitting parts are operated by time division and transmission signals to be output by the plurality of transmitting parts are transmitted by one communication path. <P>SOLUTION: The serial communication device is provided with a start bit detection part which corresponds one-to-one to the transmitting parts, and in which the transmission signals of the corresponding transmitting parts are input, and when the start bit detection part detects a start bit, the output signals of the transmitting parts which do not perform transmission for a fixed period are masked. Even when the noise is superposed on output of the transmitting parts which do not perform transmission, since the noise is masked, correct signals without being affected by the noise are transmitted. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
