ABSTRACT:
An apparatus for filming a plurality of index or library cards is disclosed which feeds, spaces and photographs the individual cards automatically. The apparatus is provided with a means for sensing the height of cards in a stack, adjusting the height of the stack so that a feeding mechanism may properly engage the cards for delivering them to a belt. The cards are photographed on the belt and are held stationary thereon by means of an electric charge on the individual cards so that they adhere to the surface of the belt. Subsequent to being photographed, the cards are restacked in the same order as they were stacked prior to being photographed.
