SHREDDER AUTO FEED SYSTEM

摘要

The present invention. is generally related to an apparatus having cutter elements (20) for destroying- articles such as paper sheets and a mechanism (23) for advancing at least a top sheet from a stack of paper in a tray (14) into the cutter elements for shredding. In one embodiment, the apparatus uses a rotatable' feed roller (24) to feed paper atop the stack to the cutter elements. The feed roller moves in an alternating manner between a lowered and raised position to engage and disengage the stack when advancing the paper therethrough. Alternatively, a rotatable cam (72) may be used. In an embodiment, the apparatus uses a rotatable drum (40) or rotatable belt (82) with an internal vacuum to lift paper from the stack and feed into the shredder mechanism.
