Abstract

195,965. Zeiss, C., [Firm of]. April 10, 1922, [Convention date]. Enlarging, copying, and reducing.-In photographic reproducing apparatus the lens system comprises a fixed member d and a movable member j<3>. The lens d and the frame g may be connected by bellows, and the lens j<3> and holder n<2> are adjustable on the guide b. The focusing is rendered automatic for different ratios of reproduction by means of grooved drums k, p controlling the movements of the supports j2 and m<2> on the guide b. The frame g is vertically adjustable in the pillar i<2>. The holder n<2> is vertically adjustable on the frame n<1> by the screw o<3>, and the frame n<1> is transversely adjustable on the support m<2> by a transverse screw m<4>.
