A lens-fitted film unit is preloaded with photographic film, and has an eight-toothed driven sprocket wheel in mesh with perforations on the film. When the photographic film is fed by one frame, the sprocket is caused to make one rotation. A shutter mechanism is cocked responsive to rotation of the sprocket. During assembly of the film unit, the shutter mechanism is cocked. The photographic film is loaded while the shutter mechanism remains cocked. In a preferred embodiment, the sprocket is set in a predetermined rotated position which is two teeth short of the position at the end of one winding up of the film. This brings the shutter mechanism into an incompletely cocked state. The photographic film is loaded while the shutter mechanism remains in the incompletely cocked state. In the film unit, a film passageway is provided behind the main body, for passage of the film. A shiftable engaging portion projects into the film passageway in retractable fashion. A notch is formed in an edge of the film, is engaged with the shiftable portion, and during assembly properly positions the film within the film passageway relative to the lengthwise direction of the film.

A pallet conveyer for successively conveying a plurality of pallets to stations arranged in accordance with a sequence of steps to be executed on each of the pallets. The pallet conveyer comprises at least two intermittent conveyers disposed in series with and spaced apart from each other, and a supplementary conveyer mounted removably between the two intermittent conveyers. The intermittent conveyer is associated with at least one work station, and is driven intermittently at a speed and an interval according to location and working time of the associated work station. The supplementary conveyer is driven continuously to convey the pallets from the preceding to the following intermittent conveyer, while absorbing the difference in speed and interval between the two intermittent conveyers.

In a magnetic disk cartridge, a magnetic disk sheet is accommodated in a casing in such a way that it may be rotated. A heat-sensitive adhesive is provided on one side of a raw sheet material composed of the same material as wear-resistant members which are to be bonded to the casing. The raw sheet material is cut into wear-resistant members and each of the wear-resistant members is heated in order to melt the heat-sensitive adhesive while the wear-resistant member is supported with a suction force. Then the wear-resistant member is released while the heat-sensitive adhesive is in a molten state, and it is pressed against the central portion of the inner surface of the casing. Thus the casing has a wear-resistant member bonded to a central portion of the inner surface of the casing.

A magnetic disk cartridge comprises a hard case, a magnetic disk sheet rotatably housed in the hard case, and a disk-shaped or polygonal liner disposed between the magnetic disk sheet and an inner wall surface of the hard case for cleaning the recording surface of the magnetic disk sheet. Internal peripheral wall sections at corners of the hard case are formed by linear portions conforming with the outer shape of the polygonal liner, and curved portions conforming with the outer shape of the disk-shaped liner.

In a decorative winding method for a magnetic tape or the like, a tape reel comprising a lower flange and a reel shaft one end of which is secured to the lower flange is supported with the other end of the reel shaft facing up. One end of a tape is clamped to the reel shaft, and the tape is wound up on the reel shaft while the tape is pushed onto the lower flange side by the weight of a cap placed on the upper side edge of the tape. An upper flange is then secured to the other end of the reel shaft, thereby obtaining the tape reel with the tape wound up in an aligned winding appearance.
