Abstract: An illumination measuring device for panoramic picture taking has a first photoelectric illumination intensity receiver which diffusely determines light falling in a first measuring region and illuminating a first panoramic portion, at least one further photoelectric illumination intensity receiver which diffusely determines light falling in a second measuring region and illuminating a further panoramic portion, and an evaluating unit determining a deviation of an illumination intensity determined by the further illumination intensity receiver from an illumination intensity determined by the first illumination intensity receiver.

Abstract: A panoramic camera has an objective drum, an electric motor which drives the objective drum and has a motor shaft, the electric motor being arranged axis-parallel to and at a distance from the objective drum and having a regulatable speed, a plurality of outputs having different speeds and connected with the motor shaft, and a plurality of intermediate outputs connecting the outputs selectively with the objective drum.

Abstract: A panoramic camera has a camera housing having a cylinder segment provided with an image window, an objective drum which is rotatable relative to the cylinder segment about a rotary axis, the cylinder segment having segment flanks located laterally near the image window, the segment flanks being provided with light catching grooves extending parallel to the rotary axis of the objective drum and ending at an angular distance from the outer edges of the cylinder segment, covered by a curvature of the drum.

Abstract: A focal-plane leaf shutter for photographic cameras, comprises an opening group of leaves and a closing group of leaves, each group having a main leaf which forms a parallelogram linkage with a pair of carrier levers, and secondary leaves. The main leaves serve to define an exposure aperture. The carrier levers are mounted by means of stationary pivot journals on a plate at one short side of the exposure aperture and the main leaves are pivotally connected by means of bearing journals to the free ends of the carrier levers. The secondary leaves are connected with the carrier levers at intervals between the pivot journals and the bearing journals. The two innermost carrier levers forming parallelogram linkages with the main leaves are mounted on a common pivot journal.

Abstract: The invention relates to a mirror mechanism for a monocular reflex camera with a laminated focal plane shutter, in which at least the opening blades of the shutter are automatically guided back into their initial positions by a spring-operated guidance member after the exposing procedure.To simplify construction of the opening blades return mechanism there is provided an arm on the shutter return mechanism which is capable of being coupled to the swivel lever for the viewfinder mirror when the opening blades move back. The swivel lever can be moved back against the action of a spring and held by a catch.

Abstract: The micro-filming apparatus comprises an object table, a camera head arranged above said table, a frame pivotally mounted on said table, a glass plate and mounting therefor mounted on said frame, said glass plate being capable of movement perpendicularly of the plane of the frame to adjust the distance between the object and the film, setting sliders mounted on said frame movable between first and second positions, a handle attached to said sliders by which movement between said two positions is effected, and coacting means arranged between said sliders and the plate to effect perpendicular movement of said glass plate on movement of said sliders, wherein on movement of said sliders into the first position the lower surface of the glass plate is brought into the picture-taking plane and on movement into the second position the upper surface of the plate is brought into the picture-taking plane.

Abstract: A microfilm camera is provided which has a camera head positioned above an exposure table. The exposure table included a pivotable glass plate and originals to be photographed can be placed beneath the glass plate or on its upper surface. To enable in-focus pictures of originals in either position to be taken, means are provided to vary the distance between the film in the camera head and the glass plate. In one embodiment the exposure table is mounted on four columns each having a lifting cam operated by a common activating handle. In a second embodiment the camera head can be raised or lowered by a handle operated eccentric cam.

Abstract: A microfilm camera has a carrier plate for holding a film sheet and a slidable carriage for sliding the carrier plate into and out of an operative position. The carrier plate is secured to the slidable carriage either directly or via a guide bush by means of three retaining screws which form the angles of a triangle which includes the geometric center of the carrier plate. Associated with each retaining screw is a support screw by means of which the distance between the carrier plate and the slidable carriage can be adjusted at each of the angles of the triangle. To enable the adjustment to be made by means of an auto-collimator, the carrier plate may be mirror-coated or the surface thereof which is intended to hold the film sheet.
