Abstract
An oblique feeding roller and a reference guide are provided on a re-conveying path for conveying a sheet in which an image has been formed on one side by an image forming unit to the image forming unit again. The sheet is obliquely fed by the oblique feeding roller. A side edge of the sheet abuts to a reference surface provided for the reference guide along a sheet conveying direction, thereby correcting the oblique motion and a positional deviation of the sheet. The reference guide is moved to a position according to a length in a width direction of the sheet which is conveyed by a movement of a cam.

A sheet conveying apparatus for conveying a sheet, comprising:
- a reference guide which is provided on a conveying path of the sheet and which has a guide surface extending along a sheet conveying direction;
- an oblique feeding unit which can obliquely convey the sheet and which abuts a side edge of the sheet against the guide surface of the reference guide;
- and
- a cam rotated by a driving source, wherein the cam moves the reference guide, while keeping the guide surface parallel to the sheet conveying direction, according to a length of the sheet in a width direction crossing the sheet conveying direction,
- wherein the cam has a plurality of cam surfaces that respectively restrict a position of the reference guide according to the length of the sheet in the width direction.
An image forming apparatus having a sheet conveying apparatus which conveys a sheet to an image forming unit, comprising:
- a reference guide which is provided on a conveying path of the sheet and which has a guide surface extending along a sheet conveying direction;
- an oblique feeding unit which is provided so that it can obliquely convey the sheet and which abuts a side edge of the sheet against the guide surface of the reference guide;
- and
- a cam rotated by a driving source, wherein the cam moves the reference guide, while keeping the guide surface parallel to the sheet conveying direction, according to a length of the sheet in a width direction crossing the sheet conveying direction,
- wherein the cam has a plurality of cam surfaces that respectively restrict a position of the reference guide according to the length of the sheet in the width direction.
