ABSTRACT:
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.
