METHOD FOR TAKING UP FILM, METHOD FOR LOADING FILM IN FILM UNIT WITH LENS AND FILM TAKE-UP SPOOL

摘要

PURPOSE: To take up film to a take-up spool without deforming the leading edge of the film, especially, to take up even the film having no perforation at its edge by taking up the film while sucking the leading edge of the film to a suction hole by taking the air in from the hollow hole of the take-up spool. ;CONSTITUTION: The suction hole 1b for sucking the film pierces the take-up part 1a for taking up the film of the take-up spool 1, and the hollow hole 1c is formed at a shaft center. Since the suction hole 1b and the hollow hole 1c communicate with each other, the air is taken in from the hollow hole 1c through the suction hole 1b. By using the spool 1 and taking the air in from the hollow hole 1c of the spool 1, the film is taken up while sucking the leading edge of the film to the suction hole 1b. Thus, the film is taken up to the spool 1 without having the perforation at the leading edge of the film caught by pawls nor bending the leading edge of the film.;COPYRIGHT: (C)1996,JPO
