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.
