Claims (1)

Patentanspruch:Claim: Kinoprojektor mit periodisch wirkendem optischem Ausgleich der absatzweisen Bildwanderung, dadurch gekennzeichnet, daß zwei zum optischen Ausgleich an sich bekannte Schwingungsspiegel -(Cl1, d%) mit zwei Greifern (^1, g2) durch Hebel zwangläufig so verbunden sind, daß sie entsprechend der jeweiligen Schaltung des Films durch einen der Greifer abwechselnd gekippt werden sowie daß während jedes Stillstands des Films im Bildfenster die Spiegel, ohne Veränderung ihrer den beiden durchleuchteten Bildern zugeordneten Kippstellungen, auf ihrer Kippachse längs dieser verschoben werden, so daß auf dem Projektionsschirm ein Bild durch das nächste ersetzt wird.Cinema projector with periodically acting optical compensation of the intermittent image wandering, characterized in that two oscillating mirrors known per se for optical compensation - (Cl 1 , d%) with two grippers (^ 1 , g 2 ) are necessarily connected by levers in such a way that they are correspondingly the respective switching of the film are alternately tilted by one of the grippers and that during each standstill of the film in the picture window the mirrors, without changing their tilting positions assigned to the two illuminated images, are shifted along their tilt axis along this, so that an image through the projection screen the next is replaced.
