Cassette with a photographic film

摘要

A cassette with a photographic film (24) includes a spool (12) provided with a retaining structure (21) for retaining a trailer of said photographic film. Further, a cassette shell (10) is provided with a spool chamber for containing said spool rotatably and with a photographic film passage port for communicating said spool chamber to an outside. Said retaining structure (48B) is so constructed that said trailer (134A) is retained when said spool (50) is rotated. In addition, there is provided a spool body (48) defined while forming a recess in a core of said spool (50) extended in longitudinal direction. A clamper member (49) fitted into said recess in said spool body in order to clamp said trailer with said spool body by connection to said spool body. Further, a foldable connector portion (47) is arranged for connecting said clamper member to said spool body foldably.
