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.
Claims12
A sheet conveying apparatus for conveying a sheet, comprising:
- a reference guide which is provided on a conveying path of the sheet along a sheet conveying direction;
- an oblique feeding unit which can obliquely convey the sheet and which abuts a side edge of the sheet to the reference guide;
- and
- a moving mechanism which moves the reference guide in a direction which crosses the sheet conveying direction,
- wherein the moving mechanism has a cam and a driving source which moves the cam and moves the reference guide in the direction which crosses the sheet conveying direction by a cam surface of the cam which is moved by the driving source.
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 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 to the reference guide;
- and
- a moving mechanism which moves the reference guide in a direction which crosses the sheet conveying direction,
- wherein the moving mechanism has a cam and a driving source which moves the cam and moves the reference guide in the direction which crosses the sheet conveying direction by a cam surface of the cam which is moved by the driving source.
