Abstract
A roll film reader/printer transports film to a selected photographic area of imagery. Transparent areas are also left at any one or more selected locations on the roll film. When it is necessary or desirable to read an image on a separate and discrete piece of film, the roll of film is transported through the reader/printer in order to display a transparent area. There, a carrier for the separate and discrete piece of film is manually inserted into the reader/printer and over the transparent area on the roll film. An optically detectable symbol may be provided on the carrier so that a signal may be given when the carrier is in a reading position. Either suitable interlock switches or signals responsive to the optically detected symbol may disable the roll film transport mechanism while the carrier for the manually inserted film is in the reader/printer.
