The Pascal is one of the first cameras for roll film, and the first with spring-motorised film advance. It was made in France by Japy Frères & Compagnie, from about 1899. It is a box camera, with a wood-and-metal body, with leather covering. It makes twelve pictures 40×55 mm on special roll film (not Kodak roll film; an interesting commercial choice).[1] The film has paper leaders, but is not backed along the whole length. According to the advertisement, it is for daylight-loading. One of the items offered is a trial roll; a spool of film without emulsion, and with cloth leaders, to practice loading and test the film advance.[1]

The camera was designed by Francisque Pascal who patented it in several countries.[2][3][4]

Most of the functions of the camera are unexceptional. As standard, it has a 69 mm f/12 achromatic lens; in an article reproduced at Collection d'Appareils, the maker offers to make the camera to order with a Zeiss Anastigmat (at a cost of 100 francs, compared to the price of 14.75 francs with the achromat).[5] The shutter is a simple one, with two instantaneous speeds (marked 'R' (rapide) and 'L' (lente), plus 'P' (pose; 'B' shutter).[6] There are three fixed aperture stops;[7] these are selected by pulling up (or pushing down) a metal tab above the lens. The shutter release button is at the top front corner of the right-hand side. Nearby is the front glass of a Newton finder that swivels about one corner to unfold into place. The finder has a catch that engages with the shutter button to lock it when the finder is folded down.

The spring motor is wound with a key on the bottom of the camera. The motor advances the film after the shutter is released. There is a frame counter in a window in the top of the camera.

Two types were made. In the first, the back and sides are hinged;[8] in the second type, the back and sides slide into place.[9]
