Title: Method and device for leading film out of cartridge
Inventor: NAGOSHI KAZUHIRO
IPC: G03D13/00
Filed: 1983-12-08
Abstract: PURPOSE:To form an air layer between a lead-out slit surface and film surface, and lead a film out of its cartridge without damaging the film surface while preventing the generation of static electricity by pressing air in the cartridge from both or one end and discharging the air from the film lead-out slit. CONSTITUTION:Normally, when the film F is led out, the film F is possibly damaged because the internal surface of the lead-out slit 11, i.e. napped part 13 for guidance on the internal surface of an opening insulating material 12 and the surface of the film F are in contact with each other. When, however, a gas such as compressed air is pressed in the cartridge 1 from gaps between a spool and caps and sent out from the part of the lead-out slit 11, the member 12 spreads outward slightly. Further, the guide napped part 13 provided on the internal surface of the member 12 becomes flat to form a buffer air layer between the member 12 and napped part 13, and the surfaces of the film F, so even when the film F is led out at a high speed, damage to its surfaces is little and this is practically used.
