摘要： A lens-fitted photo film unit provides a daylight photography mode to select no flash emission and the small stop, a daylight synchro photography mode to select normal flash emission and the small stop, and a night view synchro photography mode to select reduced flash emission and the large stop. The small stop is composed of the small stop aperture of f/16 and an ND filter of transmittance of 25% to be attached to cover the small stop aperture. The shutter speed is set at 1/64 sec. in any modes. The photo film preloaded in the lens-fitted photo film unit has ISO sensitivity 3200. The stable photographing is achieved under the wide range of brightness by the changeover of the stop, without the change of the shutter speed. In brightness of EV 9 to 11, the exposure amount becomes proper either in the daylight photography mode and in the night view synchro photography mode.

摘要： A shutter device has a front blade which is biased by a spring to a closed position for closing an exposure aperture, and a rear blade biased by a spring to an open position for opening the exposure aperture. A shutter drive lever kicks the front blade and the rear blade successively while moving to one direction. As soon as the front blade opens the exposure aperture, the rear blade closes the exposure aperture. And while the rear blade is biased by the spring to return to the initial position before opening the exposure aperture, the front blade is biased by the spring to close the exposure aperture. When the front blade and the rear blade return to the initial position by the urge of the spring, the two blades return with partly overlapped each other.

摘要： A lens-fitted photo film unit is provided with a movable stop plate formed with small and middle stop apertures. The small stop aperture has a smaller diameter, and the middle stop aperture is larger than the small stop aperture. A fixed large stop aperture, which is larger than the middle stop aperture, is disposed behind the movable stop plate. The movable stop plate is moved to position the small stop aperture at a photographic optical axis when subject brightness is a predetermined reference value or more. Similarly, the middle stop aperture is positioned at the optical axis when the subject brightness is less than the reference value and a flash switch is turned off. Further, the fixed large stop aperture is set to the optical axis when the subject brightness is less than the reference value and the flash switch is turned on.

摘要： There is disclosed a method and an apparatus of correcting image picked up from a frame photographed on a photo filmstrip through a photographic device. An exposure correction amount is calculated by use of correction parameters predetermined with regard to decrease in illuminance on a focal plane of the taking lens with radial distance from an optical axis of the taking lens, and a curvature of the photo filmstrip relative to the focal plane. The exposure correction amount is calculated for a respective pixel of the picture with regard to a relative position of the respective pixel in the frame to an optical axis of a taking lens of the photographic device. The relative positions are defined on the assumption that the photo filmstrip is held flat in a focal plane of the taking lens with a center point of the frame located on the optical axis at the photography.

摘要： A mechanism for cocking a shutter actuating lever during the one-frame advance of a photographic film having one or two perforations per frame. A cocking lever pushes the shutter actuating lever toward a cocked position when a claw lever mounted on a distal end of the cocking lever is engaged in one of the perforations along with advancing of the photographic film. When the shutter actuating lever reaches the cocked position, an arresting lever is rotated into an anti-winding position wherein the arresting lever arrests the shutter actuating lever in the cocked position and, simultaneously, engages with a film winding wheel to stop film advancing. The arresting lever is connected to the claw lever through the cocking lever so as to cause the claw lever to remove from the perforation when the arresting lever rotates into the anti-winding position. A film securing member cooperates with the arresting lever to secure the photographic film after the claw lever is removed from the perforation until the shutter actuating lever is released.

摘要： A consecutive taking camera is adapted to taking eight exposures time-sequentially in a single frame on photo film. Four shutter disks are provided with a shutter slit and rotated from an initial position upon a single releasing operation. Each shutter slit is moved past two stationary openings. A shutter-driving slide plate with a spring is moved in a releasing direction upon the releasing operation, and rotates the shutter disks. A governor mechanism is disposed in fashion couplable with the slide plate, and reduces speed of rotation of the shutter disks. The governor mechanism is coupled with, and uncoupled from, the slide plate by an intermittent toothed wheel. The intermittent toothed wheel sets the coupled state when the shutter slit is away from the stationary openings. The intermittent toothed wheel exits from the coupled state to set the uncoupled state in response to coming of the shutter slit to a predetermined angular position, which is respectively a predetermined angle short of the stationary openings. The intermittent toothed wheel keeps the uncoupled state while the shutter slit is moved past the stationary openings.
