Abstract: Provided is an easily fabricated awning-member molded article having excellent strength, and an awning formed from a plurality of such awning-member molded articles. When an awning-member molded article is viewed from its bottom surface, a small-triangular plate portion bent toward a bottom surface of a second dihedron and a small-triangular plate portion bent toward a bottom surface of a third dihedron have a predetermined thickness at their portions abutted against each other, so that the second dihedron and the third dihedron in each basic element are coupled to each other. Further, a middle-triangular plate portion bent toward the bottom surface of the second basic element and a middle-triangular plate portion bent toward the bottom surface of the third basic element are provided with a predetermined thickness at their portions abutted against each other, so that the second basic element and the third basic element are coupled to each other.
Abstract: A film magazine having a case adapted to be mounted in fixed position adjacent a motion picture camera that is adjustably movable along a fore and aft axis. The magazine includes a film slot and a film guide assembly movable along the length of the film slot for guiding the film in light tight relation through the film slot regardless of the position of the camera. The arrangement does not require rethreading of the film following each change in camera position.
Abstract: An opening and closing mechanism for photographic film cartridges of the type having a film-receiving tray with outwardly extending front and side lips and a flexible cover for the tray resealably engaged with the lips. The opening and closing mechanism includes a cartridge-receiving base with front and side lips for supporting the front and side lips of the tray. A carriage is mounted for movement with respect to the base. An elongated roller including cartridge cover-engaging fingers is rotatably and movably mounted to the carriage. Springs bias the roller toward engagement with the lips of the base. A carriage drive assembly includes a roller drive linkage, a track drive linkage, a motor and a shuttle linkage. A rack is mounted adjacent to the base for engagement by the track drive linkage.

Abstract: A case for a film camera with a film magazine which can be mounted at various positions. The case comprises at least one opening to allow passage of the film, an insertion holder for receiving essentially diametrically opposed, formed shoulders of the film magazine and comprises a lock for the latter. In order to make it possible to re-mount the film magazine in a simple manner, provision is made that the case comprises only one opening to allow passage of the film. Also, two different receiving parts are provided which can be selectively fastened to the outside of the case for covering a part of the film. Passage opening and which are provided with a clamping device for fixing the film magazine.
Abstract: Film boxes for attachment to and use with a camera are keyed and secured by thumb screws to a shutter housing of the camera to permit detachment and accurte reattachment. Light restrictive devices negate transmission of light into each film box upon removal of same. A longitudinally displaceable film reel drive permits rapid disengagement and reengagment of the film boxes without careful alignment and a belt drive prevents, through slippage, film tearing forces.
Abstract: An apparatus for pivotally mounting a film magazine to a motion picture camera which enables the film magazine to be slidably pivoted from a position wherein the film magazine is mounted substantially on top of the camera to a position wherein the film magazine is mounted substantially on the rear of the camera. Light shield means are provided to close off the adjustment aperture in the motion picture camera housing which permits the slidable pivoting motion. Brake means are provided for securing the mounting bracket in the selected pivoted position. Extraneous light is prevented from entering the motion picture camera by light securing members mounted between the camera body and the flexible light shield members.
Abstract: In a reproduction camera having a slant body and anteroinferior platforms, apparatus for setting or replacing a copy comprises a carrier which is anteroinferior and capable of moving along the slant body, where the optical axis is always vertical thereto, a copy holder which is mounted on the carrier to swing back and forth around a fulcrum, and a plate for holding down evenly a copy mounted on the copy holder by a hinge, by which the plate can be opened or closed. The fulcrum is positioned so that the total centroid of the combination of the holder, the plate and the hinge exists in the rear of the fulcrum when the plate is opened and exist in the fore of the fulcrum when the plate is closed.
