A film end holder includes a rectangular and hollow main body and a guide plate projected upward from the main body. First and second film end holders are attached to both sides of the work table of a photographic printer. The trailing end portion of a developed photographic film is inserted in the main body of the first film end holder while the leading end portion is inserted in the passage of the film carrier of the work table. Accordingly, in the beginning of printing, the developed photographic film is looped between the first film end holder and the film carrier. The leading end portion being advanced from the film carrier during printing is guided by a guide plate to enter the main body of the second film end holder. Thereafter, a loop is formed between the film carrier and the second film end holder. Therefore, the photographic film will never be brought into contact with the floor and is thus protected from dust and scratches.

Film end holder for photographic printer

A light-scattering-type smoke detector is disclosed which comprises a base portion to be secured to a ceiling, a head part forming one of the parts of a detecting portion to be detachably mounted to the base portion through setscrews passed therethrough, and a dark box forming the other of the portions of the detecting part to be detachably connected to the head part by screwing the setscrews thereto, the dark box comprising a body portion and a cover portion put one upon another. The body portion has a printed circuit board integrally secured thereto on its upper surface and the dark box is surrounded by a labyrinth around its outer periphery that is internally provided with a light projection element and a light receiving element. The smoke detector allows the dismounting of the head part from the base portion, and the dark box from the head part so that maintenance and repair of the smoke detector can be carried out quite easily.
