Abstract
A negative film handling method and apparatus in which negative films to be printed are inserted into negative film carrier sheets and the film sheets are attached side-by-side on a conveyor flexible transparent belt. Negative film inserting and removing openings provided in the film sheets are aligned with one another perpendicular to the inserting and removing direction. The negative film inserting and removing openings are opened by bending an edge portion of the flexible transparent belt.
Claims27
A negative film handling method comprising the steps of:
- inserting negative films into inserting and removing openings in negative sheets, positioning said negative sheets and attaching said negative sheets side-by-side on a flexible transparent belt in such a manner that said negative film inserting and removing openings of said negative sheets are aligned with one another perpendicularly to the negative film inserting and removing direction, and opening said negative film inserting and removing openings of said negative sheets including bending at least an edge portion of said flexible transparent belt.
An automatic negative film handling apparatus in which negative sheets into which negative films are inserted are attached side-by-side on a flexible transparent belt in such a manner that negative film inserting and removing openings of said negative sheets are aligned with one another perpendicularly to the negative film inserting and removing direction, which apparatus comprises:
- (a) negative sheet conveying means for intermittently conveying said negative sheets which contain said negative films and are attached to said flexible transparent belt;
- (b) negative sheet opening means for bending upwardly an upper side portion on the negative film inserting and removing opening side of each negative sheet and one edge portion on the negative film inserting and removing opening side of said flexible transparent belt and for bending a lower side portion of each negative sheet downwardly to open said negative film inserting and removing opening thereby to separate the end portion of each negative film from said negative film inserting and removing opening;
- (c) negative film conveying path forming means disposed perpendicularly to the direction of conveyance of said negative sheets for conveying each negative film to a printing opening section;
- (d) negative film removing position regulating means for, while said negative film inserting and removing opening is opened so as to be separated from the end portion of said negative film, bringing into coincidence the longitudinal center line of said negative film with the longitudinal center line of said negative film conveying path forming means;
- (e) negative film removing and inserting means for moving said negative film thus positioned onto said negative film conveying path and inserting said negative film into said negative sheet after printing;
- (f) negative film picture detection notch detecting means including means for detecting a picture of said negative film for feeding said negative film as required to said printing opening section;
- and
- (g) negative film feeding means operated in accordance with a signal produced by said negative film picture detection notch detecting means for feeding said negative film uniformly to said printing opening section.
