Abstract
A photographic film cassette has a connecting sheet of which a trailing end is fixed on a spool, and a front end is drawn out from a cassette shell through a film passage mouth beforehand. A developed photographic film is connected to the front end of the connecting sheet drawn out of the cassette shell. The spool is rotated to wind up the developed film in the cassette shell with the connecting sheet. In a preferred embodiment, before developing the photographic film after exposure, the exposed film is drawn out of the cassette shell, and is cut on a film trailer. As a result, the exposed film is separated into a first portion and a second portion left on the spool with a front end of the second portion drawn out. The second portion is provided as the connecting sheet. Further, a hot-melt adhesive agent is applied to the photographic film in a position to be the front end of the second portion.
