Abstract
The invention relates to a device for developing photographic film bases with a plurality of treatment tanks to be passed through consecutively, which treatment tanks are connected by transfer devices and of which at least one contains a developing fluid suitable for developing copies of negatives. In front of this developing tank in the direction of processing, a further treatment tank is disposed, having a bath fluid for reverse developing. In addition to the inlet aperture, the reverse developing tank is provided with a further inlet aperture, at the end of a guide bridging the reverse developing tank, to the treatment tank adapted for copies of negatives.
Claims9
Device for developing photographic film bases comprising
- a plurality of treatment tanks for film bases to be passed through consecutively, said treatment tanks having inlet apertures and being connected by transfer devices and guides, wherein at least one of said treatment tanks is a negative copy developing tank which contains a developing fluid suitable for developing copies of negatives, and further wherein a reverse developing tank containing a fluid bath for reverse developing is disposed in front of said negative copy developing tank in the direction of processing,
- a first movable guide element on the guide paths to the inlet apertures of different developing tanks, wherein said movable guide element is capable of switching between the guide paths leading to different developing tanks,
- a guide bridging the reverse developing tank and ending at the inlet aperture of the negative copy developing tank, wherein the guide bridging the reverse developing tank is divided into a first part and a second part, the first part comprising a convertible guide channel and the second part comprising a movably mounted element acting in one position to divert the film base emerging from the reverse developing tank to the negative copy tank.
