Abstract:
1. A sheet feeding apparatus comprising: a placement surface on which a sheet to be transported is placed; a fixed guide which abuts against one side edge of the sheet in the width direction to guide transport of the sheet; a movable guide which abuts against the other side edge of the sheet in the width direction to guide transport of the sheet while a distance between the movable guide and the fixed guide in the width direction of the sheet is adjustable; a sheet feeding roller which abuts against a surface of the sheet at a position which is at the side of the fixed guide between the fixed guide and the movable guide and rotationally drives to transport the sheet; an abutment member which is provided on the movable guide and abuts against the surface of the sheet; a support member which rotatably supports the abutment member with respect to the movable guide, wherein the support member includes a side surface opposed to the fixed guide and is arranged to project progressively to the fixed side from a downstream side to an upstream side, wherein the side surface of the support member is slanted such that as a portion of the side surface becomes nearer to the fixed quide in the width direction, a distance between the portion of the side surface of the support member and the placement surface is increased; and an elastic member which biases the abutment member toward the placement surface, wherein the abutment member has a side surface opposed to the fixed guide in the width direction, and the side surface is configured such that as a portion of the side surface becomes nearer to the fixed guide in the width direction, a distance between the portion of the side surface and the placement surface is increased.
