Abstract
Abstract A camera box for a microfilm camera for processing a film carried by an aperture card comprises an elongated housing, a magazine for a series of the aperture cards in the housing, a film exposure station arranged in the housing to receive the aperture cards from the magazine in sequence, conveyors arranged in the housing for conveying a respective aperture card carrying an exposed film, the conveyors defining a travel path for the aperture cards in the housing, and a drying station in the travel path. The throughput speed of the cards through the camera box is improved by providing a first station for completely developing the exposed film of the respective aperture card and a second, like station for completely developing the exposed film of a subsequent one of the aperture cards, the first and second developing stations being arranged in the travel path between the exposure and drying stations, and the conveyors being arranged for alternately delivering the sequence of aperture cards carrying the exposed films from the exposure station to the first and second developing stations.
