ROLLED PHOTOGRAPHIC FILM CARTRIDGE, IMAGE PICKUP UNIT AND CAMERA USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a rolled photographic film having a new width capable of realizing the improvement of easiness in handling, the reduction of leakage light and the increase of exposure frames by setting the film width within a specified range and providing perforation. SOLUTION: The film width is set between 38.5 mm and 54 mm, desirably, 46.2±1.5 mm. An image frame is not regulated particularly but it is desirable to set the length of the image frame to 41.5±1 mm and the width thereof to 56.0±1.5 mm considering the easiness in handling at a laboratory and the aspect ratio of the image frame. This size is obtained by replacing the relation between the length and the width of 645 size popular as the image frame size of 120 type or 220 type rolled photographic film, so that printing can be performed with the mask of 645 size used till now concerning the processing at the laboratory. It is good to set the perforation 102 to two or less per one frame but it is desirable to set it to one. It does not matter whatever position the perforation 102 exists at regardless of relative relation to a frame 101 but it is desirable to set the perforation 102 between the frames 101 and 101.
