Japanese Patent JP2003315965
Kind Code:
A
Abstract:
To reliably prevent a film from being illegally reloaded in a film unit equipped with a lens.
An exclusive photographic film having perforations arranged only at one end of the film in the width direction is used. A plurality of projections 44 having projecting surfaces smaller than the size of the perforation are arranged on the rear side 38 of the main body base part where the other end with no perforations of the film slides on in a film feeding direction. If a commercial photographic film having perforations on both ends of the film in the width direction is loaded in the film unit, the perforations arranged on the other end of the film in the width direction enter the projecting parts 44, and the film feeding is interrupted.
