发明名称 NEGATIVE MASK
摘要 PURPOSE:To use a negative mask for plural kinds of negative films different in picture size by releasing the fixed relation of the negative mask mounter on a printer, and changing only the position of an opening part for exposing and printing. CONSTITUTION:Negative film rollers 111-114 are driven and a negative film F135 is carried. When a notch formed in each picture at a prescribed interval along on side edge of the negative film F135 reaches the surface of a small hole 1358, mark detecting light is detected by a photodetector 13510, the photodetecting signal is carried to each operation member driving signal generating circuit. Consequently, the negative film carrying rollers 111-114 are stopped, a pressing member C is driven, an electromagnet 30 is excited, a surface part 36 to be adsorbed of a pressing plate depressing plate 35 is adsorbed, and a thin plate-like negative film pressing plate 261 of a negative film pressing pressure plate 1352 on a negative film selecting and guiding member B is depressed against a spring 291 by a pressure plate depressing arm plate 37 against a spring 38, so that the negative film F135 is fixed on an exposing and printing position.
