ABSTRACT:
A card dispensing mechanism for withdrawing individual cards from a stack thereof and feeding it to a use station including a stack support structure and a pressure plate urging the stack with the foremost card at a dispensing point. A carriage has a roller at a first end riding along a track longitudinally parallel to the foremost card front face and is engaged by a rocked lever at its opposite end and a pawl element is mounted proximate the carriage first end and projects toward engagement with the foremost card trailing edge to rotate and rock with the carriage. With the rocking of the lever on its advanced stroke the pawl element initially engages the card trailing edge to impart an advancing outwardly inclined force thereto and during the major advance of the card applies a longitudinal force thereto parallel to the card face and approaching the end of the stroke, the force is again outwardly inclined. Nip rollers are provided to engage and advance the card as it approaches the end of its pawl advanced travel to feed it to a projection station of a microfilm reader.
