Title:
CARTRIDGE FOR PHOTOGRAPHIC FILM
Document Type and Number:
Japanese Patent JP3470273
Kind Code:
B2
Abstract:
PURPOSE: To reduce an amount charged by static electricity caused by friction with the teremp of a cartridge for photographic film at the time of pulling out or rewinding the film and to prevent the film from being sensitized by the discharge of the static electricity and making noise.
CONSTITUTION: The teremp stuck to the film pull-out port of the cartridge for the photographic film is formed as the teremp 3 whose absolute amount triboelectrification is decreased by low-temperature plasma processing depending on the atmosphere of fluorine based gas. By using the teremp 3, the triboelectrification amount generated in the case of pulling out the film from the cartridge 1 and rewinding the film is reduced, and frictional resistance is reduced. By imparting water repellency and oil repellency, the cartridge suits to any environment such as low temperature, low humidity, high temperature and high humidity.
