Abstract
An apparatus for individually feeding sheets from a stack of sheets, comprises a tray for supporting a stack of sheets to be fed therefrom. A sheet feeder is provided for individually capturing a top sheet from the stack and for conveying the top sheet out of the tray. A solenoid-activated sheet hold down device is provided which includes a portion being cyclically movable toward and away from the stack for exerting a force on a next top sheet beneath the top sheet to prevent the next top sheet from being forwarded out of the tray while the top sheet is being forwarded.
