Sheet conveyance apparatus

A sheet conveyance apparatus, comprising:

• an abutment member configured to extend along a sheet conveyance direction and configured to have an abutment surface to abut against an edge in a width direction orthogonal to the sheet conveyance direction;
• a first oblique-feed roller pair configured to convey the sheet in a first direction inclined relative to the sheet conveyance direction and configured to be rotatable around an axis orthogonal to the first direction so that the sheet approaches the abutment surface in the width direction;
• a second oblique-feed roller pair configured to convey the sheet in a second direction inclined relative to the sheet conveyance direction and configured to be rotatable around an axis orthogonal to the second direction so that the sheet approaches the abutment surface in the width direction;
• and
• a conveying roller pair disposed upstream of the first oblique-feed roller pair and the second oblique-feed roller pair with respect to the sheet conveyance direction and configured to convey the sheet in the sheet conveyance direction,
• wherein the first oblique-feed roller pair is disposed on a side opposite to the abutment surface in the width direction with respect to a center line of the sheet conveyed by the conveying roller pair,
• wherein the second oblique-feed roller pair is disposed on a same side as the abutment surface in the width direction with respect to the center line of the sheet, and
• wherein an angle of the first direction with respect to the sheet conveyance direction is more than twice of an angle of the second direction with respect to the sheet conveyance direction, and the angle of the first direction with respect to the sheet conveyance direction is set in a range of 20 to 40 degrees.
