Abstract
A preexposure apparatus comprises a film supply station ST1 for arranging a film cartridge 14 containing a film 12 accommodated therein, a film-drawing station ST3 for automatically drawing the film 12 over its entire length, an exposure station ST5 for exposing a predetermined portion of the drawn film 12 with an image by the aid of an exposure section 32, a winding station ST6 for automatically rewinding the film 12 after the exposure into the film cartridge 14, and a withdrawing station ST8 for withdrawing the film cartridge 14. Accordingly, the predetermined portion of the film can be preexposed with a desired image automatically and efficiently.
Claims19
A preexposure method for photosensitive films, comprising the steps of:
- holding, with a holding means (20), (410), a shield container (14), (404) containing a photosensitive film (12), (402) wound and accommodated therein;
- automatically drawing said photosensitive film (12), (402) from said shield container (14), (404) held by said holding means (20), (410);
- relatively positioning said drawn photosensitive film (12), (402) and an exposure section (32), (436);
- exposing a predetermined portion of said photosensitive film (12), (402) with an image by the aid of a preexposure manuscript (228) arranged in said exposure section (32), (436);
- and
- automatically rewinding said photosensitive film (12), (402) after said exposure into said shield container (14), (404).
A preexposure method for photosensitive films, for preparing a preexposure manuscript (228) on which an image for preexposing a photosensitive film (12), (402) is recorded, and relatively positioning said preexposure manuscript (228) and said photosensitive film (12), (402) to expose a predetermined portion of said photosensitive film (12), (402) with said image, said preexposure method comprising the steps of:
- preparing a manuscript design with digital data;
- directly exposing a predetermined portion of a sheet manuscript (300) with an arbitrary positive image by using a laser (322) on the basis of said digital data;
- and
- preparing said preexposure manuscript (228) by using at least one of said sheet manuscript (300).
A preexposure method for photosensitive films, for preparing a preexposure manuscript (228) on which an image for preexposing a photosensitive film (12), (402) is recorded, and relatively positioning said preexposure manuscript (228) and said photosensitive film (12), (402) to expose a predetermined portion of said photosensitive film (12), (402) with said image, said preexposure method comprising the steps of:
- preparing a manuscript design with image data;
- directly exposing a predetermined portion of a sheet manuscript (300) with an arbitrary positive image from CRT (536) by the aid of an optical system for image formation (544) on the basis of said image data;
- and
- preparing said preexposure manuscript (228) by using at least one of said sheet manuscript (300).
A preexposure method for photosensitive films, for preparing a preexposure manuscript (228) on which an image for preexposing a photosensitive film (12), (402) is recorded, and relatively positioning said preexposure manuscript (228) and said photosensitive film (12), (402) to expose a predetermined portion of said photosensitive film (12), (402) with said image, said preexposure method comprising the steps of:
- preparing image data for forming said image on a plurality of frames;
- directly recording said image data and a positioning reference (306) on a sheet manuscript (300);
- arranging said sheet manuscript (300) in a processing mechanism (330) on the basis of said positioning reference (306) to perform cutting into manuscript segments (308a, 308b) having a desired number of frames;
- and
- preparing said preexposure manuscript (228) by using at least one of said manuscript segments (308a, 308b).
A preexposure method for photosensitive films, for preparing a preexposure manuscript (228) on which an image for preexposing a photosensitive film (12), (402) is recorded, and relatively positioning said preexposure manuscript (228) and said photosensitive film (12), (402) to expose a predetermined portion of said photosensitive film (12), (402) with said image, said preexposure method comprising the steps of:
- preparing image data for forming said image on a plurality of frames;
- directly recording said image data and a positioning reference (306) on a sheet manuscript (300);
- arranging said sheet manuscript (300) in a processing mechanism (330) on the basis of said positioning reference (306) to perform cutting Into manuscript segments (308a, 308b) having a desired number of frames, and forming a positioning site (310a, 310b) on said manuscript segment (308a, 308b);
- and
- preparing said preexposure manuscript (228) by arranging a plurality of said manuscript segments (308a, 308b) in a manuscript holder (226) on the basis of said positioning sites (310a, 310b).
A preexposure method for photosensitive films, comprising the steps of:
- preparing a preexposure manuscript (520) which is composed of a reversal film (514) to record an image thereon and which has a length corresponding to a plurality of photosensitive films (518);
- forming said preexposure manuscript (520) to have a loop-shaped configuration and arranging said preexposure manuscript in an exposure section (554);
- and
- exposing a predetermined portion of said photosensitive film (518) with said image by the aid of said exposure section (554) while moving said preexposure manuscript (520) in a circumscribing manner in a state in which a part of said photosensitive film (518) is overlapped with a part of said preexposure manuscript (520) in said exposure section (554).
