摘要： A lens-fitted photographic film unit has a flash device for emitting a flash of light. A charge switch is adapted to bring the flash device into an on-state, either by rotation of a film advancing wheel, or when a shutter device is cocked. When the flash device is in the on-state, a main capacitor is charged so as to allow emission of a flash of light. In a preferred embodiment, the charge switch is initially turned on so as to keep the flash device in the on-state. In another preferred embodiment, the flash device is in the on-state while the charge switch is on, and is in the off-state while the charge switch is off, in response to the shutter device. When the lens-fitted photographic film unit is contained in a wrapper, an insulating tape is inserted between a positive electrode of the battery and a contact segment. Upon the wrapper being torn off the lens-fitted photographic film unit, the insulating tape is pulled out of the lens-fitted photographic film unit, so as to bring the flash device into the on-state.

摘要： A lens-fitted photographic film unit has a film supply chamber preloaded with unexposed photographic film. A cassette-containing chamber contains a film cassette. The film after exposure is wound on a spool of the cassette. The film unit is provided with a mechanism for exposing the film in a succession of frames. An axial hole is formed in an upper end of the spool. Knurled inner teeth are formed inside the axial hole. A wind-up wheel is mounted on the film unit over the cassette-containing chamber to be externally operable for rotation. A drive shaft on the wind-up wheel protrudes into the cassette-containing chamber, and is received in the axial hole. Knurled outer teeth about the drive shaft mesh with the inner teeth on the spool. The drive shaft and spool will thus mesh with each other in any relatively rotated position thereof, which avoids loss of usable film.

摘要： First and second parts of a lens-fitted photographic film package are fastened to each other through engagement between hooks and engaging portions which are formed integrally on the first part and the second part, respectively. Holes are formed at the root of the hooks. Each hook is formed with a projection having a sloping surface which extends from the root of the hook toward an engaging surface of the hook and is inclined in a direction to occupy the space behind the hole. A stick-like tool is inserted into the hole in the direction in which the first part is pushed onto the second part to assemble the parts. The tool pushes the hook by sliding along the sloping surface of the projection and bends the hook in a direction to disengage the engaging surface of the hook from the engaging portion.

摘要： A camera with a taking lens system changeable in focal length between a relatively long and a relatively short focal length, which has an exposure control meter comprising a masking member disposed in front of a photoelectric element to provide an electric exposure control output, and formed with first and second openings for allowing light that has passed therethrough to fall on the photoelectric element at different incident angles. A light stop member is movable to cover or uncover the second openings upon changing the taking lens system between the relatively long and relatively short focal lengths. Upon changing the taking lens system to the relatively short focal length, the light stop member is moved to uncover all of the first and second openings so as to increase the quantity of light falling on the photoelectric element and to permit that light to fall at an increased incident angle; and, on the other hand, upon shifting the taking lens system to the relatively long focal length, the light stop member is moved back so as to cover only the second opening means while uncovering the first openings, thereby to decrease the quantity of light falling on the photoelectric element and to permit that light to fall only at a decreased incident angle.

摘要： A stop lever is rotatable on a light shielding tunnel with an exposure aperture. When the stop lever is at a fast shutter speed position, a support pad is located below a lower metal plate of a synchronization switch of a flash circuit. The support pad holds the lower metal plate to limit rotation of a shutter blade, so that photography is carried out at a fast shutter speed. The synchronization switch is turned on after the exposure aperture is fully open. When the stop lever is at a slow shutter speed position, a support pad is away from the lower metal plate to obtain a slow shutter speed. It is possible to obtain a fast shutter speed by providing a light shielding tunnel with a fixed stopper to limit rotation of the shutter speed, and a slow shutter speed by providing a light shielding tunnel without a stopper.

摘要： A lens-fitted photo film is pre-loaded with a photo film. Imaging frames are created on the photo film by releasing the shutter. There is aspect ratio information optically prerecorded on the photo film outside of the imaging frames, and associated with a respective one of the imaging frames. The aspect ratio information includes two dots, and represents an aspect ratio in two bits. The imaging frames are printed in accordance with the aspect ratio. The lens-fitted photo film unit has a viewfinder with a view field of the aspect ratio represented by the aspect ratio information.

摘要： A lens-fitted photo film unit contains a cartridge shell into which an IC memory is incorporated, and a roll of photo filmstrip having a magnetic recording layer. Unit ID data and date-of-manufacture data are written in the IC memory in the factory. A data recording circuit is provided on a flash circuit board. The data recording circuit is connected to the IC memory through a printed circuit board mounted to a cartridge chamber of the film unit. A finder mask and a photo sensor for detecting the position of the finder mask are mounted in the film unit. The photo sensor is connected to the data recording circuit, to write photographic data corresponding to the output of the photo sensor in the IC memory at each exposure. Before printing, the data written in the IC memory is read to be recorded on the magnetic recording layer of the photo filmstrip by use of an external recording device which is connectable to the IC memory through an interface terminal which is exposed to an exterior of the film unit.

摘要： A lens-fitted photo film unit includes a cassette containing chamber and a photo film roll chamber. The cassette containing chamber contains a cassette. The photo film roll chamber contains a roll of unexposed photo film drawn out of the cassette. The cassette incorporates a photo film port shutter rotatable between a closed position to block a photo film passage port and an open position to open the photo film passage port. The photo film is wound into the cassette by one frame after an exposure is taken thereon. A rotating member is connected to the port shutter and rotatable between a first position associated with the open position of the port shutter, and a second position associated with the closed position of the port shutter. The rotating member is disconnected from the port shutter at a time of moving the cassette in the cassette containing chamber for unloading the cassette from the cassette containing chamber. A torsion coil spring rotates the rotating member from the first position to the second position in response to external operation effected prior to moving the cassette in the cassette containing chamber. The cassette is unloaded from the cassette containing chamber after the photo film is wound therein.
