Abstract
Abstract A continuous taking camera has eight exposure chambers arranged in two horizontal rows and four vertical columns. One 35 mm full size original frames of photographic film is divided into eight sub-frames. One taking lens is disposed in front of each of the exposure chambers. A stationary shutter plate is disposed behind the taking lenses. Openings are formed in the stationary plate behind the respective lenses. First and second shutter disks are rotatably supported coaxially on the stationary plate on a single shaft. A first group of two holes is formed in the first disk. A second group of two holes is formed in the second disk. The second disk is rotated by the rotation of the first disk, there being a pin-and-slot lost motion connection between the two disks, so that different sets of holes in the disk register with each other, depending on the direction of rotation of the disks. Thus, the holes of the groups are either in registry with or displaced from each other, in accordance with a direction of rotation of the disks. When the holes are in registry and the disks are rotated, they open/close the eight stationary openings sequentially. The disks are actuable through one complete cycle of movement to take sequential scenes on the eight sub-frames.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
228 words
A continuous taking camera comprising: 2N exposure chambers arranged in a matrix for allowing light to fall on photographic film, so as to split at least one full size original frame into sub-frames arranged in two rows across the width of said film and in N columns along the length of said film, wherein N is an integer equal to at least 3; 2N taking lenses disposed respectively in front of said exposure chambers; a stationary plate disposed between said taking lenses and said exposure chambers; 2N stationary openings formed in said stationary plate in registry with said exposure chambers; first and second shutter disks rotatably supported on said stationary plate; a first hole group formed in said first disk and constituted of M holes, wherein M is an integer equal to at least 2; a second hole group formed in said second disk and constituted of M holes; and means for displacing said first and second disks relative to each other in order to change said first and second hole groups between an open condition wherein holes of respective hole groups register with each other and a closed condition wherein holes of respective hole groups are displaced from each other, said hole groups being adapted to open/close said 2N stationary openings sequentially, said two disks being so actuable as to take sequential scenes on said 2N sub-frames.
Claim 2
Dependent Claim
228 words
A continuous taking camera comprising: 2N exposure chambers arranged in a matrix for allowing light to fall on photographic film, so as to split at least one full size original frame into sub-frames arranged in two rows across the width of said film and in N columns along the length of said film, wherein N is an integer equal to at least 3; 2N taking lenses disposed respectively in front of said exposure chambers; a stationary plate disposed between said taking lenses and said exposure chambers; 2N stationary openings formed in said stationary plate in registry with said exposure chambers; first and second shutter disks rotatably supported on said stationary plate; a first hole group formed in said first disk and constituted of M holes, wherein M is an integer equal to at least 2; a second hole group formed in said second disk and constituted of M holes; and means for displacing said first and second disks relative to each other in order to change said first and second hole groups between an open condition wherein holes of respective hole groups register with each other and a closed condition wherein holes of respective hole groups are displaced from each other, said hole groups being adapted to open/close said 2N stationary openings sequentially, said two disks being so actuable as to take sequential scenes on said 2N sub-frames.
