Abstract: A film font for use in conjunction with photocomposing equipment includes a rectangular piece of film having a pair of apertures at either end spaced to fit over a corresponding number of support pins on a font-carrying drum. The film element includes, at one end, a rigidifying bar adapted to fit snugly against the first paid of pins and, at the other end, a cam action slide adapted to lock against the second set of pins to maintain the font in rigid position.

Abstract: In a roll film camera combined with a long length film magazine detachably mounted on the rear of the camera body, a film contained in the supply spool in the magazine is pulled past an exposure aperture by an intermittent-drive film advancing sprocket, while the take up spool in the magazine is driven by a separate driving means through a slip clutch to take up the film advanced from the sprocket. In one embodiment, this arrangement is provided with a film guiding means having buffering and braking functions mounted in the magazine and positioned between the sprocket and the take up spool so that when the sprocket is stopped while the separate driving means is driving the take up spool, the film is brought into frictional engagement with the surface of the film guiding means, whereby the film is braked and stabilized from residual movement during exposure.
