Abstract
A sheet conveying apparatus includes first and second rotator pairs, a moving member including an abutment portion against which a front end of the sheet conveyed by the first rotator pair abuts and a guide member provided at upstream, in the sheet conveying direction, of a nip portion of a second rotator pair. The guide member configured to be movable to a first position where the guide member guides the sheet toward the moving member in a projection state and to a second position away from the moving member more than the first position and turns to the second position during when the sheet is conveyed by the second rotator pair.
Claims17
A sheet conveying apparatus comprising:
- a first rotator pair conveying a sheet;
- a second rotator pair provided downstream, in a sheet conveying direction, of the first rotator pair;
- a moving member including an abutment portion against which a front end of the sheet conveyed by the first rotator pair abuts, and being movable from a projection state in which the abutment portion projects into a sheet conveying path upstream, in the sheet conveying direction, of a nip portion of the second rotator pair to a passage state in which the sheet is permitted to pass through the moving member as the abutment portion is pressed by the sheet conveyed by the first rotator pair;
- and
- a guide member provided upstream in the sheet conveying direction of the nip portion of the second rotator pair and movable to a first position where the guide member awaits the sheet conveyed from the first rotator pair and guides the front end of the sheet toward the moving member in the projection state and to a second position away from the moving member more than the first position, the guide member configured to move from the first position to the second position by being pushed by the sheet which is nipped by the first and second rotator pairs, and to return from the second position to the first position after the sheet comes out of the first rotator pair and before the sheet comes out of the second rotator pair,
- wherein the moving member is a rotator configured to rotate in one direction by being pressed by the sheet.

- and
- a guide member being movable from a first position, in which the guide member awaits the sheet conveyed from the first rotator pair and guides the front end of the sheet toward the moving member in the projection state, to a direction away from the moving member, the guide member configured to move from the first position to the direction away from the moving member if the sheet is nipped by the first and second rotator pairs and pushes the guide member, and to return to the first position after the sheet comes out of the first rotator pair and before the sheet comes out of the second rotator pair,
- wherein the moving member is a rotator configured to rotate in one direction by being pressed by the sheet.
