Compact Sheet Feeder

Shown and described is an apparatus for feeding multiple documents into a low volume printer. This document handler feeds a combination of sheets or envelopes. As shown, the device can handle up to five documents. These five documents may, for example, comprise a four-page letter and an envelope. Each slot can accommodate a document up to 8"x14" in size in either orientation.

Two picker wheel assemblies are provided. One assembly 10 is shown. Each picker wheel assembly include five separate picker wheels. Each of the pair of picker wheel assemblies is aligned so that their resilient picker fingers 12, 14, 16, 18 and 20 are arranged at 72 degrees intervals about the center of shaft 22 and are correspondingly positioned. Five input slots 24, 26, 28, 30 and 32 are shown. Each slot includes a cut-out portion for receiving only its associated picker finger.

Gate 34 is provided to act as a stop against which each document is aligned prior to entry into the feed path of the utilizing printer. A five-lobe cam 36 is mounted on the same shaft 22 as picker wheel assembly 10. When cam 36 is in its zero position, gate 34 obstructs exit from every document input slot.

When the two picker fingers 12 cooperatively associated with slot 24 move through their first 16 degrees of motion, gate 34 opens enough through the action of the first cam lobe to allow a sheet or envelope to pass from slot 24. Resilient fingers 12 sweep the first document into feed roll pai...
