    摘要: PROBLEM TO BE SOLVED: To provide a sheet feeding device that can reduce size at lower cost in comparison with a sheet feeding device used for a conventional apparatus, and further has good setting properties of bundle of sheets.SOLUTION: The sheet feeding device includes a movable wall 6 which is tiltable to regulate the leading edges of sheets stacked. When a sheet feed roller 5 is operated to perform a sheet feeding operation, a loop is formed in the uppermost sheet Sa. After formation of the loop, the movable wall 6 is moved to a regulation release position to remove the loop formed in the uppermost sheet Sa. After removal of the loop, the movable wall 6 is returned to a regulation position to raise the leading end of the uppermost sheet Sa so as to separate the uppermost sheet from the second and subsequent sheets.
