Abstract
A film processing apparatus includes a housing and a pair of continuous belts disposed within the housing in a laterally spaced relationship. Guide rollers within the housing guide the belts about parallel serpentine paths through the housing. Drive rollers engaged with the belts drive the belts in synchronization about the paths through the housing. A film carrier card having attachment elements for selectably engaging the belts is provided, such that the film carrier card is transported through the housing by the belts.
