发明名称 ROLL FILM READER/PRINTER WITH MANUALLY INSERTABLE DISCRETE FILM
摘要 <p>ROLL FILM READER/PRINTER WITH MANUALLY INSERTABLE DISCRETE FILM A roll film reader/printer transports film to a selected photographic area. 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 film, "card", the roll of film is transported through the reader/printer in order to display a transparent area. There, the separate and discrete film "card" is manually inserted into the reader/printer, over the transparent area on the roll film. Suitable interlock switches disable the roll film transport mechanism while the manually inserted film is in the reader/printer.</p>
