Arrangement for introducing band light-sensitive material into developing device and the developing device provided therewith

An arrangement for introducing a band light-sensitive material in daylight from cassettes having a guide part into a treatment station of a developing device, comprising a receiving part arranged to be located on a developing device and to light-tightly receive a guide part of cassettes;

• means for subdividing the interior of said receiving part and including at least one separating element insertable into the interior of said receiving part so as to form at least two compartments therein, whereby in the absence of said separating element a greater cassette can be inserted into the interior of said receiving part, whereas in the presence of said separating element two smaller cassettes can be inserted into the interior of said receiving part each in the respective one of said compartments thereof;
• and means for light-tightly closing the interior of the developing device from the interior of said receiving part and including a closing element provided in each of said compartments at its end adjacent to the developing device and opening in response to insertion of the guide part of a respective one of the cassettes into the interior of said receiving part.
