Relay apparatus and image forming system

摘要

Disclosed is an image forming system including: an image forming device to notify a downstream post-processing device of sheet information relating to a sheet on which an image is formed, before the sheet is discharged, and to notify the downstream post-processing device of set separation information indicating a final sheet of each set of document in synchronization with the sheet information relating to the final sheet of each set in case that a plurality of sets of document are printed, the image forming device being compliant with a first communication system; a post-processing device which is connected to a downstream of the image forming device and is compliant with a second communication system which is different from the first communication system; and the relay apparatus which is connected to the image forming device through the first communication system and is connected to the post-processing device through the second communication system.

主权项

1. A relay apparatus comprising:
a receiving unit to receive set separation information indicating a final sheet of each set of documents to be printed, from an image forming device which is compliant with a first communication system, the image forming device notifying at least one downstream post-processing device of sheet information relating to a sheet on which an image is formed, before the sheet is discharged, and the image forming device notifying the downstream post-processing device of the set separation information in synchronization with the sheet information relating to the final sheet of each set of documents in a case in which a plurality of sets of documents are printed, wherein the at least one downstream post-processing device comprises a first post-processing device which is connected to a downstream side of the image forming device and is compliant with a second communication system which is different from the first communication system; a storage unit to store the set separation information received by the receiving unit; and a notification unit to notify the first post-processing device of the set separation information stored in the storage unit, in synchronization with a timing at which the final sheet of the each set indicated by the set separation information is discharged to the first post-processing device.
