A film cassette includes a first cylindrical body forming a film supply section, a second cylindrical body forming a film take-up section, and a coupling section extending between the first and second cylindrical bodies and connected at both ends to the two cylindrical bodies thereby integrally coupling the cylindrical bodies. The coupling section has an outer face continuous with the outer peripheral surfaces of the first and second cylindrical bodies. First cylindrical body includes a ridge protruding from the outer peripheral surface thereof, to which is applied an urging force to rock the film cassette around that cylindrical body with the ridge thereon.
