A sheet feeding apparatus for feeding sheets is provided with a multi feed detecting section for detecting multi feed of conveyed sheets in a predetermined detection position of a conveyance path, and first and second discharge sections to which multi-fed sheets with the multi feed detected are discharged, and corresponding to one of a front end position of the multi-fed sheets at the time the multi feed detecting section detects the multi feed of sheets, a sheet storage state of the second discharge section, sheet storage states of the first and second discharge sections, a size of sheets and weighing, selects one of the first and second discharge sections to discharge the multi-fed sheets to the selected discharge section.

Sheet feeding apparatus

Tray means for stacking sheets, pickup means for separating and for conveying sheets into a single sheet on the tray means, and sheet conveyance means for conveying a sheet separated by the pickup means to a predetermined processing position are provided. Projecting guide means project from a sheet support surface of the tray means into a notched opening of the sheet is provided; and an oblique surface is formed to prevent a trailing side edge of the opening from catching on a leading side edge of the opening of a lower sheet when feeding an uppermost sheet to the projecting guide means. This makes it possible to feed only the uppermost sheet downstream without an opening edge formed in the uppermost sheet from interfering with an opening edge of a lower sheet.
