Abstract
Abstract A pair of parallel card hoppers are spaced from a projector film gate. A reversible drive roller and two idler pinch rollers, defining two reversible, oppositely transporting nips, are positioned near the hoppers for transporting a card from either hopper and later delivering it to the other hopper. A second reversible drive roller and idler pinch roller, defining a third, reversible-go, or no-go nip, are positioned near the film gate for transporting the card from one of the first two nips into the film gate, and then retrieving it from the film gate and delivering it to the other nip, or for preventing the card from entering the film gate, causing the trailing edge of the card to follow the first reversible drive roller from the one nip to the other.
