Sheet feeding apparatus and two side image forming apparatus therewith










Image Number 5 for United States Patent #5931455.

A sheet feeder for feeding a sheet from a sheet stacker. The sheet feeder includes: a main body of the sheet stacker for holding plural stacked sheets; a movable bottom plate, provided on the bottom portion of the main body and supported bivotally on an axis, for supporting the plural stacked sheets; a lifting lever for lifting the movable bottom plate; and plural pickup rollers, aligned on an axis in a direction perpendicular to a sheet feeding direction, for having a pressure contact with a sheet of the plural stacked sheets on the movable bottom plate, and for feeding the sheet from the main body in the sheet feeding direction. In the sheet feeder, a protruded portion is formed either on the movable bottom plate or on the lifting lever so that a contact portion where the movable bottom plate comes in contact with the lifting lever is of a point contact, and the contact portion is provided at the center of the closest two of the pickup rollers in the direction of their axis.
