Abstract

A sheet feeding apparatus includes a regulating member, provided along a feeding path of the sheet, for regulating a widthwise position of a sheet by being abutted by an edge of the sheet A sheet turning mechanism including a first pair of first driving roller and first follower roller for nipping and feeding the sheet is disposed at a position upstream of the regulating member, as is a second pair of second driving roller and second follower roller, where the first pair and the second pair are disposed in a line extending in a widthwise direction of the feeding path, and where the first and the second driving roller are rotatable in opposite directions to turn the sheet to abut the edge of the sheet to the regulating member. A sheet correcting mechanism is disposed downstream of the sheet turning mechanism, and includes a feeding roller and a third follower roller for correcting an attitude of the sheet by feeding the sheet so as to abut the edge of the sheet turned by the sheet turning mechanism to the regulating member.

Claims9

Dependent claims

A sheet feeding apparatus comprising:

a regulating member for regulating a widthwise position of the sheet by being abutted by a lateral edge of the sheet;
attitude changing means for changing an attitude of the sheet;
inclined feeding means for correcting an inclination of the sheet by feeding the sheet with inclination in a direction of abutting the lateral edge of the sheet to said regulating member;
moving means for moving said regulating member and said inclined feeding means between respective correcting positions for correcting an inclination of the sheet and respective retracted positions in which said regulating member and said inclined feed means do not contact the sheet,
wherein, in a state in which said regulating member and said inclined feeding means are in their respective retracted positions, said attitude changing means changes the attitude of the sheet inclinedly such that a trailing edge of the sheet is offset toward said regulating member, and thereafter, said moving means moves said regulating member and said inclined feeding means to their respective correcting positions to correct the inclination of the sheet by abutting a lateral edge of the inclined sheet to said regulating member.
