Abstract
1,187,460. View-finder systems. CARL ZEISS JENA VEB. Nov.7, 1967, No.50515/67. Heading G2A. A view-finder system consists of parts 1 and 2 which are assembled together to provide the viewfinder system, part 1 having an image-erecting mirror 3 and view-finder 5, and part 2 being provided with mirrors 6, 7 positioned at a right angle with respect to each other. Both the mirrors are laterally adjustable against resilient means 10, 14 and mirror 2 may be rotated by plate 16 and adjustable screw 17 to bring the relative positions of the mirrors to exactly a right angle. When this is achieved the mirrors are cemented in position at 18', 19'.
