    摘要： A store for record carriers contained in storage units arranged side by side on a support and capable of being withdrawn from said store, said units being selectable by means of codes representing the storage units. Each storage unit is provided with a coding surface on one side. At least one seeker head is provided which is movable relative to said storage units to scan the coding surfaces and to detect a coding surface corresponding to the selected code.

    摘要： An exposure measuring apparatus has a lighting element which can be connected to and influenced by a source of supply potential. Means are provided for presetting the light emission of the lighting element. A photo-sensitive receiver influenced by prevailing light conditions is connectable with the source of supply potential and influences the light emission of a second lighting element which is connected in circuit with the photosensitive receiver and at least one resistance attenuation element. The resistance attenuation element or elements are adapted to adjust the light emission of the second lighting element in accordance with required exposure factors when the supply potential is connected. The lighting elements are formed as light source pillars the color of which are influenced by their supply frequency, e.g. electro luminescent plates. The source of supply potential is an alternating current source and the second lighting element is connected therewith via a variable frequency generator the frequency of which is influenced by the setting of the resistance attenuation elements. The first and second lighting elements are arranged to illuminate respective surfaces positioned immediately adjacent one another whereby when the color and brightness of each of the surfaces is equal, the exposure factors are set to values required for accurate exposure.

    摘要： A photographic camera having a housing, a shutter mechanism and an aperture passage is provided with an additional shutter mechanism for flashlight operation purposes. The additional shutter mechanism includes a drive ring mounted within the housing arranged to be driven by a spring, a plurality of shutter blades pivotably mounted on the housing to form an additional shutter adapted to be driven by the drive ring between a closed position and a fully open position via a pivoted drive lever, a setting ring mounted on the housing settable into ''''flash'''' or ''''daylight'''' exposure positions, release means mounted on the housing for locking the drive ring in a cocked position, an actuating member provided on the drive ring for actuating a flash ignition circuit when the drive ring is running-off out of the cocked position in use during a flash exposure, a stop member provided on the setting ring for stopping the drive ring runningoff out of the cocked position, a first projection on the setting ring arranged to release the release means when the setting ring is set in the ''''daylight'''' position, and a second projection on the setting ring arranged to move the drive lever to open the additional shutter when the setting ring is in the ''''daylight'''' position.

    摘要： An image-focusing plate for cameras comprises two or four parts formed from wedge prisms arranged to form an image-intersection line which is displaced along its length through an angle not exceeding 100* or intersects another image intersection line at an angle gamma not exceeding 100*. The image-intersection line or lines where they intersect a center of symmetry of the plate are at an angle Beta smaller than 46* relative to an end of maximum cross-sectional area of a wedge from which a part is formed.

    摘要： A reflex camera having a photoelectric exposure meter includes a light concentrator guide having reflective surfaces mounted on and arranged behind the reflex mirror which is partially transparent (half silvered). The light concentrator guide is provided with a first reflective surface lying transversely of the optical axis of the object lens of the camera and a second reflective surface lying transversely of the optical axis. The second reflective surface reflects light rays entering the light concentrator guide from the object lens of the camera towards a light emergent surface thereof. A photoelectric receiver is situated opposite the light emergent surface of the light concentrator guide to receive the light rays.
