More Information
Summary:The utility model relates to a paper tester for automatically testing the length of a photographic paper, which comprises a paper-advancing passageway, a photographic paper in the paper-advancing passageway, a paper-advancing passageway baffle which is arranged out of the paper-advancing passageway, paper-advancing rollers which are arranged on the paper-advancing passageway baffle and mutually roll to compact and advance the photographic paper, and paper sensors which are arranged on the paper-advancing passageway baffle for testing the photographic paper. The paper tester can automatically test the length of the photographic paper, improves the speed for producing a photo album, and reduces the length error of the photo album caused by manual test. Furthermore, with the two sets of paper sensors, the paper tester reduces the moving distance of the photographic paper, thereby reducing the volume of a paper length-testing mechanism and lowering the cost thereof.
