Abstract
Abstract A card transport apparatus (12) carries cards along a card transport path through card processing stations (14, 74, 76). The transport apparatus (14) includes a vertically adjustable card carriage (16) for retaining cards along a card transport path throughout the entire card processing operation through the card processing stations (14, 74, 76). The card carriage (16) grips the cards with independently pivoting gripping arms (52, 54), actuated open by push solenoids (18, 20, 22) for picking up and releasing cards.
