摘要： Apparatus including a feed bin attached to a frame for supporting cards in parallel planes slightly inclined from vertical. A picker knife extends into the feed bin and periodically elevates the first card in the bin into a feed position. A feed plate mounted for rotation in a plane substantially parallel to the plane of the card in feed position is provided with a plurality of card-engaging protrusions which contact the edge of the card in the feed position and move the card in its plane past read heads. The picker knife elevates the card in synchronism with the rotation of the feed plate through the utilization of camming pins secured to the feed plate which contact the bottom of the picker knife to cause the latter to extend into the feed bin.
