Abstract: A casing, particularly for roll film cartridges, includes a hollow housing having a chamber for closely receiving a film cartridge and a channel which communicates with the chamber. The channel is operative for receiving a length of roll film which extends out of the cartridge when the latter is inserted into the chamber. The channel extends tangentially to the chamber and has at least one flat inner surface along which the length of roll film can extend to be held in flat condition.

Abstract: Relative movement is effected between the original and the projection system of the copying machine, and the latter projects images of successive transverse strip-shaped sections of the original onto the recording medium. The projection system comprises a plurality of lens-row systems. Each lens-row system includes a first lens row which receives light from a strip-shaped section of the original and projects into an intermediate image plane, and a second lens row which receives light from the intermediate image plane and projects that light onto the recording medium. The lens-row systems are spaced apart in a direction transverse to the direction of elongation of the individual lens rows. The light passing through each lens-row system includes a plurality of central rays, each passing through the optical center of one lens element of the first lens row and through the optical center of the corresponding lens element of the second lens row.

Abstract: A camera body has mounted on it a lens mount which is pivotable relative to the camera between an operative and an inoperative position. A mechanism in the camera is activated and transports film from the camera film chamber through the camera during movement of the lens mount from one to the other (or from the other to the one) of the aforementioned positions.

Abstract: A camera body has an upper end provided with a slot and with a film chamber which is so dimensioned that it can receive an instant-picture film pack of rectangular shape in such an orientation that those narrow edges of the film sheets adjacent which each sheet has a compartment containing a supply of developer, are located beneath and adjacent to the film slot through which each exposed film sheet is expelled.

Abstract: The camera has a housing and a lens. A film transport mechanism is arranged in the housing. An operating element includes a member which is displaceable by a user in longitudinal direction of the optical axis of the lens and which, during at least part of such displacement, actuates the film transport mechanism. The operating element may include two of these members; if so, they are located at opposite lateral sides of the lens and are coupled so as to move in unison.

Abstract: A motion-picture camera has a housing provided with a chamber having a film compartment. A plate-shaped carrier is detachably mountable in this chamber and can carry one or two film cassettes, so that one cassette is located within and the other cassette is located without the film compartment. A movable cover closes an open side of the chamber.

Abstract: An accessory unit, for example an electronic flash unit, for use with photographic apparatus has a housing provided with one or more connecting elements for detachably connecting the unit to the apparatus. The housing has a through-going, essentially slot-shaped passage through which self-developing film sheets ejected from the apparatus can pass, or through which a strap or other retaining element of the camera can extend which holds the unit adjacent to the camera even when the unit is not in operative position, i.e. when the unit is detached from the photographic apparatus.

Abstract: A cinematographic camera has a housing composed of a main section which carries at its narrow front side a photographic lens, and a cover section which straddles the main section and is provided with a viewfinder. The main section can be telescoped into and out of the cover section and in so doing respectively blocks and unblocks the viewfinder. A handgrip is pivoted to the main section and can be displaced between a position in which it hugs the main section and overlies the photographic lens which it thereby protects, and a position in which it projects from the main section so that it can be gripped by a user.
