タ伝送装置。 When the transmission request signal sent from the transmitting side is off, an idle pattern is generated, and when the transmission request signal changes from off to on, an on pattern of a predetermined length is generated, and reception is detected by this on pattern. On-sign detection for detecting the on-pattern in a data transmission device that transmits a signal to the transmitting side, then receives data sent from the preceding transmitting side, and turns off the reception detection signal based on the idle pattern. an idle code detection circuit for detecting the idle pattern, and an on-sign detection circuit that is set when detecting the on-pattern to turn on the reception detection signal; A flip-flop that is reset to turn off the reception detection signal when detected, and the idle code detection circuit, after the idle pattern is no longer detected, the on-sign detection circuit does not detect the on-pattern within a certain period of time. When the flip-flop is set, and after the data goes down during reception,
A data transmission device comprising: a monitoring circuit that sets the flip-flop when the flip-flop is restored.
