摘要： A copying machine for photographic reproduction, comprising a central unit including devices for unrolling, cutting and transporting photographic paper, a photosensitive paper exposing chamber, and a print development unit. The copying machine includes a removable module for forming a light image of an original document to be copied. A plurality of modules each adapted to form a light image of original documents of different types can be removably mounted on the central unit, whereby different types of original documents can be copied. The copying machine also comprises a removable cassette which stocks photographic paper and which is manufactured with plastic material through a thermal forming process. The cassette has two lateral walls between which a mandrel, supporting a photographic paper roll, is pressure mounted. Two felt rings are sticked on the two ends of the mandrel, and rub against the lateral walls of the cassette to prevent rotation of the mandrel by inertia and also to produce a certain tension in the paper during unrolling. A module for automatically preparing and regenerating chemical baths used in the print development unit, can be added to the copying machine.
