Patent ID: 7455290

Claim:
A method of feeding sheets to a sheet processing apparatus, comprising: positioning a first guiding member adapted to move on a stacking plate along a width dimension thereof perpendicular to a sheet feeding direction and to rotate around a vertical axis, the first guiding member having a vertical guiding surface for positioning sheets disposed on the stacking plate; adjusting an angle of the vertical guiding surface on the stacking plate at an angle with the sheet feeding direction using an angle adjustment mechanism, the angle adjustment being independent from movement of the first guiding member along the width dimension; and stacking sheets on the stacking plate, the sheets being to be fed into the sheet processing apparatus; wherein positioning the first guiding member does not adjust the angle of the vertical guiding surface; wherein the first guiding member includes a slant surface at a lower portion adjacent to the stacking plate, the slant surface being disposed in such a manner that the distance between the slant surface and the sheets increases downward.
