ABSTRACT:
A cassette for light-sensitive photographic material which is to be transferred between the cassette and a copying apparatus having one or more doors which can be opened and closed. The cassette has a housing provided with an open side which can be closed by a removable cover, and it also has a wall provided with a slot connectable to an opening of the copying apparatus. A pair of rollers is mounted inwardly adjacent the slot and at least one of these can move towards and away from the other roller between one position in which the rollers define a gap for passage of the photographic material and another position in which the rollers bear upon each other and form a seal against the entry of light from the slot into the cassette. An arrangement is provided which automatically moves the movable roller into the sealing position in response to placement of the cover on the open side and another arrangement automatically moves the movable roller to the gap-defining position in response to closing of the door or doors of the copying apparatus to which the cassette is connected.
