<p>PURPOSE:To provide a multiplex transmission device capable of shifting all communication nodes to the sleep state and preventing an increase of the dark current even if an abnormality occurs on either a wake-up dedicated line or a multiplex transmission line by transmitting the sleep judgment information of the communication nodes with multiplex signals via the multiplex transmission line and the wake-up dedicated line. CONSTITUTION:A multiplex transmission device is provided with multiple communication nodes A, B, C connected via a multiplex transmission line 4 and transmitting and receiving control signals via the multiplex transmission line 4, starting means 3 starting the communication nodes A, B, C, a signal forming means forming the on/off signals starting the starting means 3, transmission lines 5, 51 transmitting the on/off signals to the starting means 3, a detecting means 11 detecting that the communication nodes A, B, C are set to the operation releasable state, and a releasing means 12 releasing the operation of the communication nodes A, B, C in response to the output.</p> |
