Abstract

In a sheet conveyance system in which a plurality of apparatuses each including a communication unit with a plurality of communication channels are connected, and a sheet is conveyed between the apparatuses, each of the plurality of communication channels can be switched between a transmission mode and a reception mode. When a plurality of transmission channels are set by channel assignment, communication can be executed by giving a priority to each transmission destination. If transmission data are accumulated in an apparatus, and they include data for a transmission destination with a higher priority over the current data transmission destination, the number of transmission channels is increased, and the priority is raised.

Dependent claims

A sheet conveyance system which includes a plurality of apparatuses,

each of the apparatuses comprising:
a plurality of communication channels for communicating sheet transfer data to another one of the plurality of apparatuses and capable of being switched between a transmission mode and a reception mode;
a determination unit adapted to determine whether or not a plurality of untransmitted data are present in the apparatus;
and
a control unit adapted to change a setting of the reception mode of a communication channel among the plurality of communication channels into a setting of the transmission mode when said determination unit determines that the plurality of untransmitted data are present in the apparatus,
wherein said control unit transmits the plurality of untransmitted data using the communication channel to which the transmission mode is set.
