A transmission managing apparatus included in an information transmitting system comprising a serial bus, an IRM node, which has a resource register for storing a channel used for an information transmission executed in a time division manner on the serial bus and a transmission occupation period occupied for the information transmission, for indicating the channel and the transmission occupation period and a general node for insuring a non-used channel and a preservable period, which is the transmission occupation period, that can be occupied, while referring to a memory content of the transmission state memory, to thereby carry out the information transmission. The transmission managing apparatus is provided with: a comparator for monitoring whether or not the memory content is updated; and a command generator for reporting a fact of the updating through the serial bus to the general node when updated.
