PURPOSE:To prevent an adverse effect caused by static electricity by performing antistatic processing, that means, processing for preventing the occurrence of the static electricity itself or processing for swiftly leaking generated charges to a part with which film comes into contact. CONSTITUTION:The film F is housed in a cartridge 10 in a light shielded state and the cartridge 10 is constituted of an initial winding part 11, a part 12 for taking up photographed film and an intermediate part 13. IN order to prevent the static electricity from occurring on the contact part of film, an antistatic agent is applied, irradiated with a radiant ray or a hydrophilic group is chemically inducted to the surface of the contact surface or part of the film F, or the synthetic resin material of construction material whose electrostatic charging series is approximate to that of the synthetic resin material for forming the film is used as the synthetic resin for forming the contact surface or the part of the film F. In order to provide conductivity to the contact part, said part is formed of a conductive synthetic resin, a metallic film is formed by the vapor deposition or application or plating of a material having conductivity or a sheet metal material having conductivity is arranged there. Thus, the adverse effect caused by the static electricity can be effectively prevented even if the film is made to travel at high speed. |
