Abstract

An image forming system includes an image forming apparatus, an image reading apparatus, a connecting conveyance path that branches from a second main conveyance path of the image reading apparatus and joins a first sub conveyance path of the image forming apparatus, and configured to convey an original from the image reading apparatus to the image forming apparatus. The system controls conveyance of the original so that a first side becomes a side that faces an image forming unit if the first side of the original is designated as the image formation side or so that a second side becomes the side that faces the image forming unit if the second side of the original iFs designated as the image formation side.

Dependent claims

An image forming system including an image forming apparatus for forming an image on a recording material and an image reading apparatus for reading an original,

wherein the image forming apparatus comprises:
a first main conveyance path configured to convey a recording material from a storage unit to a discharge unit;
an image forming unit arranged on the first main conveyance path and configured to form an image on the recording material;
a first reversing unit configured to reverse a side of the recording material that faces the image forming unit by reversing a conveyance direction of the recording material after the recording material is conveyed through the first main conveyance path;
and
a first sub conveyance path configured to convey the recording material after the conveyance direction of the recording material is reversed by the first reversing unit to a first main conveyance path,
wherein the image reading apparatus comprises:
a second main conveyance path configured to convey an original fed from a feeding unit;
a reading unit arranged on the second main conveyance path and configured to read the original;
a second reversing unit configured to reverse a conveyance direction of the original;
and
a second sub conveyance path configured to convey the original after its conveyance direction is reversed by the second reversing unit to a second main conveyance path, and
wherein the image forming system further comprises
a connecting conveyance path that branches from the second main conveyance path of the image reading apparatus and joins the first sub conveyance path of the image forming apparatus, and configured to convey the original from the image reading apparatus to the image forming apparatus;
a first determination unit configured to determine a first side and a second side of the original based on a result of reading the original by the reading unit;
an acceptance unit configured to accept designation information that designates which of the first side and the second side of the original is to be an image formation side;
and
a conveyance control unit configured to control conveyance of the original in accordance with a result of the determination of the first determination unit so that the first side becomes a side that faces the image forming unit if the first side of the original is designated as the image formation side or so that the second side becomes the side that faces the image forming unit if the second side of the original is designated as the image formation side.

15 more elements

An image forming apparatus comprising:

a feeding unit configured to feed an original;
a reading unit configured to read the original fed from the feeding unit;
a first conveyance path having a reversal function that reverses the front and back of the original, and configured to convey the original;
a second conveyance path having a reversal function that reverses the front and back of the original, and configured to convey the original;
a connecting conveyance path that branches from the first conveyance path, joins the second conveyance path, and is configured to convey the original to the second conveyance path after the original is conveyed through at least a portion of a conveyance section in the first conveyance path;
an image forming unit configured to form an image on the original after the original is conveyed through at least a portion of a section of the second conveyance path;
a determination unit configured to determine a first side and a second side of the original based on a result of reading the original by the reading unit;
an acceptance unit configured to accept designation information that designates which of the first side and the second side of the original is an image formation side;
and
a conveyance control unit configured to control conveyance of the original in accordance with a result of the determination of the determination unit so that the first side becomes a side that faces the image forming unit if the first side of the original is designated as the image formation side or so that the second side becomes the side that faces the image forming unit if the second side of the original is designated as the image formation side.
