Filtervorschaltgerät für fotografische Vergrößerungsgeräte und Repro- Kameras.Filter ballast for photographic enlargers and repro cameras.

Gegenstand der Erfindung ist ein Zusatzgerät für fotografische Vergrößerungsgeräte und Repro- Kameras zur automatischen Vorschaltung verschiedener Farbfilter.The invention relates to an accessory for photographic Enlargers and repro cameras for automatic pre-switching of various color filters.

Der Gegenstand der Erfindung ist nach beiliegender Zeichnung wie folgt beschrieben.The object of the invention is according to the accompanying drawing described as follows.

An das Gerät 1 uiird das Filtergerät 2 aufgesetzt. Die Blende 3 welche an einem Anschlag 4 anliegt, kann über deren Drehpunkt mittels der Zahnstange soujie Ritzel eingeschwenkt werden. Die Schwenkbewegung führt der mit der Zahnstange fest verbundene Magnet 6 durch, sobald er einen Stromimpuls über die Zuleitung erhält. Nach abschalten des Stromes, wird die Blende 3 mittels der Rückholfeder 8 in Anfangsstellung bis zu dem Anschlag 4 gebracht. In dieser Konstruktionsanordnung können mehrere Filter übereinander angeordnet sein.The filter device 2 is attached to the device 1. The aperture 3 which rests against a stop 4 can be pivoted in via its pivot point by means of the rack soujie pinion. the The magnet 6, which is firmly connected to the rack, performs a pivoting movement as soon as it receives a current pulse via the supply line receives. After the current has been switched off, the diaphragm 3 is moved in the initial position up to the stop 4 by means of the return spring 8 brought. In this construction arrangement, several filters can be arranged one above the other.
