ABSTRACT:
A sequential taking camera has four taking lenses. A stationary plate is disposed behind the lenses. Four stationary openings are formed in the stationary plate, each behind a respective one of the lenses. Two rotary disks are disposed behind the lenses, and rotated in response to a single operation of a shutter release button, so as to render the four stationary openings effective sequentially. A shutter plate is disposed behind the lenses in slidable fashion. Four shutter slits are formed in the shutter plate and each is associated with a respective one of the four stationary openings. When the shutter plate is slid, the slits move past the stationary openings respectively associated therewith, and open and then close the stationary openings thus rendered effective. Thus four imaging sub-frames are created consecutively on a photographic film. In a preferred embodiment, a pin is disposed on either disk. A first retaining bent portion is associated with the release button, and receives the pin, when the shutter button remains inactive, and retains the disks against the bias of a spiral spring mechanism. When the button is depressed, the pin is released from the first retaining portion. A second retaining bent portion associated with the shutter button comes in turn into the path of the pin, receives the pin after being released from the first retaining portion and during rotation of the disks, and retains the disks substantially in an initial rotational position against the spiral spring bias.
