Abstract
The present invention relates to a sheet conveying apparatus, comprising: a conveying portion conveying a sheet; a shutter member having an abutting surface for abutting the sheet to correct skew feeding; a biasing member for biasing the shutter member to position at a first position where the leading end abuts against the abutting surface; and a support mechanism which movably supports the shutter member to move in an order of the first position, a second position to which the shutter member moves by the sheet against biasing from the biasing member, and a third position where the shutter member abuts the sheet and stands by to move to the first position when a trailing end of the sheet passes the shutter member, while keeping the abutting surface facing upstream.
Claims17
A sheet conveying apparatus, comprising:
- a conveying portion which conveys a sheet;
- a shutter member having an abutting surface that abuts against a leading end of the sheet to correct skew feeding of the sheet conveyed by the conveying portion;
- a biasing member which applies a biasing force to the shutter member to position at a first position where the leading end abuts against the abutting surface;
- and
- a support mechanism which movably supports the shutter member such that the shutter member moves in an order of the first position, a second position, and a third position, while keeping the abutting surface facing upstream in a sheet conveying direction,
- wherein the second position is a position to which the shutter member moves by the sheet being conveyed against the biasing force of the biasing member, and
- the third position is a position where the abutting surface is positioned upstream in the sheet conveying direction of a position of the abutting surface at the second position and where the shutter member abuts the surface of the sheet being conveyed and stands by to move to the first position when a trailing end of the sheet passes the shutter member.
An image forming apparatus, comprising:
- a conveying portion which conveys a sheet;
- a shutter member having an abutting surface that abuts against a leading end of the sheet to correct skew feeding of the sheet conveyed by the conveying portion;
- a biasing member which applies a biasing force to the shutter member to position at a first position where the leading end abuts against the abutting surface;
- a support mechanism which movably supports the shutter member such that the shutter member moves in an order of the first position, a second position, and a third position, while keeping the abutting surface facing upstream in a sheet conveying direction,
- wherein the second position is a position to which the shutter member moves by the sheet being conveyed against the biasing force of the biasing member, and
- the third position is a position where the abutting surface is positioned upstream in the sheet conveying direction of a position of the abutting surface at the second position and where the shutter member abuts the surface of the sheet being conveyed and stands by to move to the first position when a trailing end of the sheet passes the shutter member;
- and
- an image forming portion which forms an image on the sheet fed from the sheet conveying apparatus.
A sheet conveying apparatus, comprising:
- a conveying portion which conveys a sheet;
- a shutter member having an abutting surface that abuts against a leading end of the sheet;
- a pair of rollers which nips a sheet during a movement of the shutter member while being pressed against the sheet in a state where the leading end of the sheet abuts against the abutting surface;
- a biasing member which applies a biasing force to the shutter member to position the shutter member at a position where the leading end abuts against the abutting surface;
- and
- a support mechanism which movably supports the shutter member so that the shutter member performs a crank-movement.
