Abstract

See full text

An apparatus for the day light processing of an exposed photographic film wound on a spool including an essentially cylindrical container, a lid to close the container, both made of a material impervious to light, together with a device to rotate the spool with the film wound therein and a film retaining device located in the container. The film retaining device includes at least one tongue extending inwardly from the inner wall of the container, which upon the rotation of the spool in an unwinding direction, enters between a front end of the film and a first outer winding of the wound film and guides the front end to a stop.
