JPH04125553A - Magnetically recordable anti-static photographic film cartridge - Google Patents

Abstract

PURPOSE:To reduce the formation of a static mark and the malfunction of a camera by rolling a photographic film which is provided with a magnetic layer on the opposite surface from a photograph constituting layer and putting the film in a specific cartridge shell. CONSTITUTION:The photographic film which has the photograph constituting layer, including a photosensitive silver halide emulsion layer, on one surface of a base and the magnetically recordable magnetic layer on the opposite surface is rolled to its overall constant length and put in the cartridge shell. When a sheath cylinder 1 is rotated clockwise, hooks 122 and 222 of peak pieces 12 and 22 are disengaged and hooks 123 and 223 are engaged to lock the sheath cylinder 1 and a fitting cylinder 2, thereby forming a tunnel slit 5. Then when a scroll is rotated anticlockwise, the photographic film is easily and securely led out of the cartridge by the assistance of a handling claw 23 while slipping on the internal surface of the cylinder 2 with its own unwinding force.
