Sheet skew feed correction apparatus, image forming apparatus and skew feed correction apparatus

摘要

A sheet skew feed correcting apparatus is provided which includes: a driving rotation member that is driven to rotate; a first driven rotation member that is pressure contacted against the driving rotation member; a first holder rotatably holding the first driven rotation member; a second driven rotation member that is pressure contacted against the driving rotation member; a second holder rotatably holding the second driven rotation member; and a shutter portion with which a leading end of a sheet comes into contact for skew feed correction, the shutter portion moving pivotally with one end portion thereof supported by the first holder and another end portion thereof supported by the second holder; wherein the shutter portion has abutting portions with which the leading end comes into contact, and a coupling portion extending so as to couple the abutting portions together between the first and the second driven rotation members.

主权项

1. A sheet conveying apparatus comprising:
a first driven rotation member; a second driven rotation member provided at a position different from the first driven rotation member in a rotational axis direction of the first driven rotation member; a driving rotation member configured to rotate by receiving a driving force, the driving rotation member including a first rotation portion configured to contact with the first driven rotation member and a second rotation portion configured to contact with the second driven rotation member; a first abutting portion against which a leading edge of a conveyed sheet abuts, the first abutting portion provided at a first position; a second abutting portion against which the leading edge of the conveyed sheet abuts, the second abutting portion provided at a second position different from the first position in the rotational axis direction; a first holder configured to hold the first driven rotation member and the first abutting portion, wherein the first driven rotation member is rotatable with respect to the first holder and the first abutting portion is movable with respect to the first holder; a second holder configured to hold the second driven rotation member and the second abutting portion, wherein the second driven rotation member is rotatable with respect to the second holder and the second abutting portion is movable with respect to the second holder; and a connecting portion configured to connect the first abutting portion and the second abutting portion, wherein the connecting portion, the first abutting portion and the second abutting portion integrally move from a home position by the first abutting portion and the second abutting portion being pushed by the conveyed sheet, wherein, in a state that the connecting portion, the first abutting portion and the second abutting portion are at the home position, a center of gravity of the connecting portion is set at an inner side of an outer periphery of the first driven rotation member when viewed in a direction parallel to the rotational axis direction, and wherein the first holder holds the first driven rotation member so that an inner end of the first driven rotation member facing the connecting portion is located downstream of an outer end of the first driven rotation member facing away from the connecting portion, and the second holder holds the second driven rotation member so that a second inner end of the second driven rotation member facing the connecting portion is located downstream of an outer end of the second driven rotation member facing away from the connecting portion.
