Abstract A film cassette unloading and film processing device comprises a light-sealable container having means to hold a film cassette in such a manner that a length of film can be withdrawn therefrom, together with a film cutting means. A lid member of a processing tank of the film-holding spiral type, is rotatably but detachably mounted in a light-tight manner in one side of the container, the spiral being attached to the lid member and so located in the container that the film from a cassette can be wound thereon. On the opposite side of the container there is located a tank-completing base member which, together with the lid member and the spiral, forms a processing tank of the film-holding spiral type. The base member is so held in a light-tight manner that, when the film from the cassette has been wound onto the spiral and its end cut free from the cassette, the base member can be fitted on to the lid member and the tank can be completed while both members are connected to the light-tight container, whereupon the processing tank can be removed from the container as a unit once it has been assembled.
A combined film cassette unloading and film processing device which comprises a light-tight closable container comprising, in its interior, means for holding a film cassette to enable a piece of film of determined length to be withdrawn therefrom, together with a film cutting means; a lid member of a processing tank of the film-holding spiral type being rotatably but detachably mounted in a light-tight manner in one side of the container; a spiral being attached to the inner side of the said lid member and so located in the container that the film from a cassette can be wound thereon; and a tank-completing base member located on the opposite side of the container which base member together with the lid and the spiral form a processing tank of the spiral film holding type, the base member being so held in a light-tight manner that, when the film from the cassette has been wound onto the spiral and when the end of said film piece has been cut off from the cassette, the base member can be fitted on to said lid member whilst both are still connected to the container in a light-tight manner, whereupon the completed processing tank can be removed as a unit from the container as an entity once it has been assembled.
