    摘要: A film carrier (1) for use with photographic enlargers has a base plate (1) with base runners (3) and a slider (8) with slider runners (9). Slider runners (9) and base runners (3) contact only the edges of the film strip, allowing the image portion of the film strip to remain untouched by the film carrier. Permanent magnets (4) embedded in base plate (1) attract steel strips (10) embedded in slider (8), thus causing slider (8) to be attracted to base plate (1). This magnetic force secures the film strip, placed between slider (8) and base plate (1), in the film carrier. A frictive coating (11) on slider runners (9) allows the film strip to move with slider (8) to facilitate the alignment of the image to be printed to opening (5).
