Abstract

The invention relates to an apparatus for thermal development having a receiver for receiving an imagewise exposed thermal film, an accumulator for gathering the film, a drive for advancing the film from the receiver to the accumulator, a heater located between the receiver and the accumulator for developing the film, a compound image scanner for scanning the film after it has been thermally developed, the scanner having a first light source and a fist sensor placed for forming a first electronic record of the image formed on the developed firm by reflection, a second light source and a second sensor placed for forming a second electronic record of the image by an opposing reflection, and a third sensor and a third light source placed for forming a third electronic record of the image formed by transmission, and a lighttight container for the receiver and the heater.
