Abstract
Abstract A reverse mirror for reversing an image is disposed between a subject holder and an object lens. The reverse mirror and the object lens are moved for varying image magnification and focusing the image. A movable mirror disposed between the object lens and a platen can selectively establish a focusing optical system for focusing the image of an original on the platen, a focusing optical system for focusing the image of the original on an index plate, and a focusing optical system for focusing the image of the index plate on the original plate. After a prescribed number of originals have been photographed on a photosensitive member, the platen and mask plates are moved to predetermined positions to photograph marks necessary for cutting and bookbinding in non-image areas on the photosensitive member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
A process camera comprising: a subject holder for supporting one, at a time, of a plurality of originals each composed of a page or a combination of pages; an object lens; a movable platen for mounting a photosensitive member thereon, said movable platen being associated with movable mask plates, said subject holder, said object lens, and said movable platen being successively arranged in the order named along an optical path from said subject holder toward said platen through said object lens; and the arrangement being such that said originals can successively be supported on said subject holder and exposed to light to produce respective images thereof which are focused by said object lens and reproduced on said photosensitive member according to a programmed sequence.
Claim 2
Dependent Claim
124 words
A process camera comprising: a subject holder for supporting one, at a time, of a plurality of originals each composed of a page or a combination of pages; an object lens; a movable platen for mounting a photosensitive member thereon, said movable platen being associated with movable mask plates, said subject holder, said object lens, and said movable platen being successively arranged in the order named along an optical path from said subject holder toward said platen through said object lens; and the arrangement being such that said originals can successively be supported on said subject holder and exposed to light to produce respective images thereof which are focused by said object lens and reproduced on said photosensitive member according to a programmed sequence.
Claim 3
Dependent Claim
71 words
A process camera according to claim 1, further including a reverse mirror disposed between said subject holder and said object lens for reversing the images, said reverse mirror being movable parallel to an original supporting surface of said subject holder and being movable in the direction of an optical axis of said object lens, said object lens and said reverse mirror being movable for varying image magnification and focusing the images.
Claim 4
Dependent Claim
143 words
A process camera according to claim 1, further including a movable mirror disposed between said object lens and said platen and movable into and out of an optical path of said object lens; an index plate positioned in conjugate relationship to a photosensitive member supporting surface of said platen with respect to said movable mirror when said movable mirror projects into said optical path of the object lens; an illuminating light source for illuminating said index plate; and said movable mirror being selectively movable into a position for establishing a focusing optical system for focusing the images of the originals on said platen, a position for establishing a focusing optical system for focusing the images of the originals on said index plate, and a position for establishing a focusing optical system for focusing the image of said index plate on said subject holder.
Claim 5
Dependent Claim
101 words
A process camera according to claim 1, wherein said platen and said mask plates are movable to respective predetermined positions for photographing marks necessary for cutting and bookbinding in non-image areas on the photosensitive member after said originals have been photographed, and wherein in case said photosensitive member is of the positive-positive type, said platen and said mask plates are movable to respective predetermined positions for photographing marks necessary for cutting and bookbinding in non-image areas on the photosensitive member, and a white original is photographed in non-image areas to eliminate any black non-image areas, after said originals have been photographed.
Claim 6
Dependent Claim
68 words
A process camera according to claim 1, or 4, further including a display unit for displaying the directions of the originals to be placed on said subject holder according to a prescribed format, and photographing switches selected according to the directions of the originals placed on said subject holder, the arrangement being such that the originals will be photographed only when the selected photographing switches are properly directed.
Claim 7
Dependent Claim
91 words
A process camera according to claim 1, further including a cartridge for storing said photosensitive member, said cartridge having grips on opposite sides thereof and wheels rotatably mounted on a bottom thereof, and a cartridge loading device including guide surfaces for guiding said cartridge when the cartridge is loaded, the arrangement being such that after the wheels on one side have been placed on said guide surfaces by holding one of said grips, the other grip is held and the wheels on the other side are placed on said guide surfaces.
Claim 8
Dependent Claim
103 words
A process camera according to claim 1, further including a suction plate capable of attracting said photosensitive member and movable along said platen for transferring the photosensitive member to and receiving the photosensitive member from said platen; and a pair of grip rollers for gripping and feeding said photosensitive member, said grip rollers being movable between a position for transferring the photosensitive member which is unexposed to said platen via said suction plate and a position for receiving the photosensitive member which is exposed from said platen via said suction plate and for feeding the received photosensitive member to an image developing machine.
Claim 9
Dependent Claim
36 words
A process camera according to claim 1, further including a pinhole forming device disposed upwardly of said platen for forming a positioning pinhole in said photosensitive member while the photosensitive member is mounted on said platen.
