Definitions

  • This invention relates to a photographic film stamping device for stamping out an end portion of a photographic film strip to a given shape.
  • the utilization is made of a flexible leader sheet with the exposed film strip attached at its one end. It is general to attach the film strip to the film leader sheet by means of various types of splice tape.
  • the utilization of splice tape does not always provide reliable splice of the leader sheet and the film strip and, in addition, since the splice tape is not reusable as well as expensive, it is not economical to splice the leader sheet and the film strip by a splice tape.
  • a leader sheet of a type having retainer projections with which one end of a film strip is detachably engaged In order to eliminate these problems, there has been proposed by the applicant of this invention a leader sheet of a type having retainer projections with which one end of a film strip is detachably engaged.
  • Film strips used in company with a leader sheet of this type must have coupling holes engageable with the retainer projections.
  • the film strip For preventing the film strip from inclining with respect to the leader sheet, the film strip must have at least two coupling holes and is formed in accurate positions with respect to the retainer projections of the leader sheet.
  • a new photographic printing system which is called an advanced photographic system
  • a film cartridge is equipped with a rotary spool having a pair of retainer projections to which the film spool is attached and rotation of which causes movement of the film strip our of and into the film cartridge.
  • a processed film strip is pulled out of and pushed into the film cartridge by means of rotation of the spool.
  • the film strip is required to have a tapered tongue at an end for convenience of insertion of the film strip into the film cartridge through an egress/ingress slot as well as coupling holes in precise positions at the trailing end of the film strip for reliable attachment.
  • Japanese Unexamined Patent Publication No. 2 - 272539 teaches a film cartridge which prevents the film strip from being scratched and provides easy withdrawal of the film strip.
  • This film cartridge has a spool having a flange formed with an annular peripheral lip at each end thereof for controlling expansion in diameter of a roll of the film strip on the spool with the effect of preventing the film strip from being brought into contact with the interior surface of the film cartridge shell.
  • the film cartridge is provided with a separator guide therein engageable with the film strip at its tongue formed with a side notch.
  • the film strip in particular the tongue formed with a side notch, is brought into engagement between the side notch and the annular peripheral lip and is separated from the major portion of the film roll.
  • the leader of the film strip is guided by the separator guide and certainly directed to the film egress/ingress slot of the film cartridge.
  • a processed film strip has its tongue torn from the side notch and damaged, it is hard to bring the tongue of the film strip into engagement between the side notch and the annular peripheral lip, which is always undesirable for the film strip to be smoothly and easily withdrawn from the film cartridge. For this reason, such a film strip must be reshaped so as to have a flawless tapered end of the tongue and a faultless side notch. It is also necessitated for the trailing portion of a film strip to be reshaped so as to have a flawless end and faultless coupling holes.
