Abstract
A continuous taking camera has a plurality of exposure chambers disposed linearly. Two shutter discs rotated by a motor are provided at the back of the exposure chambers. Each shutter disc is formed with two movable shutter openings at positions different in distance from the axis of rotation of the shutter disc. When the motor is energized by a shutter release operation, the motor causes the two shutter discs to perform one rotation for sequentially opening and closing the exposure chambers starting from an outermost exposure chamber. A 35 mm full size original frame is divided in the longitudinal direction of the film into four sub-frames. Scenes for eight sub-frames are taken using two full size original frames.
Claims20
A continuous taking camera comprising:
- means defining at least three exposure chambers disposed linearly in the direction of advance of a photographic film such that at least one full size original frame of said photographic film is divided into at least three sub-frames;
- at least three taking lenses each disposed in front of a respective one of said exposure chambers;
- and
- shutter means for taking scenes for said at least three sub-frames, said shutter means comprising at least one shutter disc rotatable about an axis and having two movable shutter openings, a fixed plate for rotatably supporting said shutter disc, and at least three stationary shutter openings being linearly formed in said fixed plate in registry respectively with said exposure chambers, said two movable shutter openings lying on a straight line passing through said axis and differing in distance from said axis for sequentially opening and closing said three stationary shutter openings.

A continuous taking camera comprising:
- means defining two exposure chamber groups each including four exposure chambers disposed linearly in the direction of advance of a photographic film such that at least one full size original frame of said photographic film is divided into two series of four sub-frames each;
- eight taking lenses one disposed in front of each of the eight exposure chambers;
- and
- shutter means for sequentially taking scenes for the eight sub-frames, said shutter means comprising two shutter discs one for each of said exposure chamber group, said shutter discs each having an axis of rotation, a fixed plate for rotatably supporting said shutter discs, said shutter discs each having two movable shutter openings, said fixed plate having eight stationary shutter openings linearly formed to register one with each of said eight exposure chambers, said two movable shutter openings lying on a straight line passing through the associated said axis and differing in distance from said associated axis, and each said movable shutter opening passing before two of said stationary shutter openings.

- means defining a plurality of exposure chambers disposed linearly in the direction of advance of a photographic film such that at least one full size original frame of said photographic film is divided into a plurality of sub-frames;
- a plurality of taking lenses each disposed in front of a respective one of said plurality of exposure chambers;
- and
- shutter means for allowing light from a continuously taken scene to fall on each of said plurality of exposure chambers, said shutter means being actuable once to take sequence scenes successively for said plurality of sub-frames;
- wherein each of said plurality of sub-frames has a size obtained when dividing a panoramic size original frame into a plurality of areas, and said panoramic size original frame has a size such that upper and lower sides of said full size original frame are partially masked.
