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.

A method and apparatus for cutting a web into a specified length in which an upper cutting edge and a lower cutting edge are provided respectively above and below the web run at a constant speed. The web is cut into the specified length by moving said upper cutting edge vertically while said upper and lower cutting edges are swung in the web movement direction. The swinging and vertical movements of said cutting edges are accomplished by rotation of an eccentric crank shaft driven by a DC motor. A rotation angle of the eccentric crank shaft and a movement length of said web are outputs provided in the form of pulses, respectively, in order to coincide a movement speed of the web with a swinging speed of the cutting edges in cutting said web.

A preassembled film cartridge is magnetically gripped by an arm and pivotally delivered between chucks which are moved towards each other to grip the ends of the cartridge spool. A stand mounting chucks is then moved under the cartridge, and the chucks pinch the slotted shell thereof to release the end cap, whereafter the stand is withdrawn to expose the gripped spool. The end of a precut film strip is then inserted in the aligned spool slot, and the spool is rotated to wind the film thereon. The stand is then moved back under the spool, carrying with it the shell and end cap, whereafter a capper engages the end cap and completes the cartridge reassembly. The chucks release the shell, the stand is again withdrawn, an arm magnetically engages the loaded cartridge, and the chucks release the spool, whereafter the cartridge is pivotally removed from the apparatus by the arm.
