Abstract
A sheet conveying apparatus includes: a shutter member against which a leading edge of a sheet being conveyed abuts, for a skew feed correction, wherein the shutter member is pressed and moved by the sheet; and an actuation member which moves the shutter member that has been pressed and moved by the sheet being conveyed to a retracted position at which the shutter member is retracted from a sheet conveying path and holds the shutter member at the retracted position until the leading edge of the sheet being conveyed by the second conveying rotary member is nipped by the transfer nip portion.
Claims12
A sheet conveying apparatus, comprising:
- a first conveying portion which conveys a sheet;
- a second conveying portion, disposed downstream of the first conveying portion in a sheet conveying direction, having a nip portion that nips and conveys a sheet;
- a third conveying portion, disposed downstream of the second conveying portion, which nips and conveys a sheet;
- a shutter portion against which a leading edge of the sheet being conveyed abuts downstream of the first conveying portion and upstream of the nip portion of the second conveying portion,
- an urging portion configured to urge the shutter portion to a position at which the shutter portion abuts against the leading edge of sheet being conveyed, wherein the shutter portion is pressed and moved by the sheet being conveyed, against an urging force of the urging portion;
- and
- an actuation portion which moves the shutter portion that has been pressed and moved by the sheet being conveyed to a retracted position at which the shutter portion is retracted from a sheet conveying path and holds the shutter portion at the retracted position until the leading edge of the sheet being conveyed by the second conveying portion is nipped by the third conveying portion.
An image forming apparatus, comprising:
- a first conveying portion which conveys a sheet;
- a second conveying portion, disposed downstream of the first conveying portion in a sheet conveying direction, having a nip portion that nips and conveys a sheet;
- an image transfer portion which transfers a toner image to a sheet at a transfer nip portion disposed downstream of the second conveying portion in the sheet conveying direction;
- a fixing portion which fixes, to the sheet, the toner image transferred to the sheet by the image transfer portion;
- a shutter portion against which a leading edge of the sheet being conveyed abuts downstream of the first conveying portion and upstream of the nip portion of the second conveying portion;
- an urging portion configured to urge the shutter portion to a position at which the shutter portion abuts against the leading edge of sheet being conveyed, wherein the shutter portion is pressed and moved by the sheet being conveyed, against an urging force of the urging portion;
- and
- an actuation portion which moves the shutter portion that has been pressed and moved by the sheet being conveyed to a retracted position at which the shutter portion is retracted from a sheet conveying path and holds the shutter portion at the retracted position until the leading edge of the sheet being conveyed by the second conveying portion is nipped by the transfer nip portion.
