Abstract
A transport belt for an automatic camera vacuum feed and hold down system is provided. The movable, flexible opaque transport belt has a substantially uniform bottom surface facing the exposure platen and a top surface provided with at least one transverse resilient belt flexing member. The belt flexing member is preferably a curved plastic member having memory which assumes a first, curved position to create at least one air channel beneath the belt. The air channels reduce the length of time required to evacuate air beneath the belt. During vacuum hold down for exposure, the resilient belt flexing member assumes a second position, substantially parallel to the platen and the air channels are eliminated, such that the bottom belt surface presents a substantially flat uniform background surface during exposure.
