As for the method of (3) above, for example, JP-A-52-
As disclosed in Japanese Patent No. 82336, an "automatic negative film processing device" has been proposed in which a negative film insertion/extraction port of a negative sheet is opened, a negative film is taken out, subjected to printing, and then returned again. In addition, in order to integrate and record the frame data of the negative film on the negative sheet, Japanese Patent Application Laid-Open No. 53-51730 describes a method in which the negative sheets are sequentially pasted onto a roll-shaped strip having a recording body so that the negative film is perpendicular to the roll. is proposed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for handling negative film that facilitates the insertion and removal of negative films in a method in which negative sheets are sequentially attached to a rolled band.

A composite body of a negative sheet containing a negative film applied to the present invention and a flexible transparent band includes a negative sheet film inserted under the band along near the longitudinal side edge of the band. A plurality of negative sheets are fixed to a band so that the ejection ports are arranged in sequence.

A method and apparatus for achieving the above-mentioned objects of the present invention are such that when a composite is fed out from a supply section that supplies a rolled composite and is traveling on a conveyance table, a first guide The plate separates the flexible transparent band and the upper side piece of the negative sheet insertion/ejection port fixed thereto, and the negative film end and the lower side piece of the negative sheet insertion/ejection port, and separates the second guide plate and the side piece adjacent to it. A direction changing roller provided at a downstream position integrally bends the end of the negative film and the lower side piece of the negative sheet downward to maintain separation from the upper side piece and the flexible transparent strip, and the third The negative film edge and the lower side piece of the negative sheet are separated by the guide plate and the fourth guide plate, and the lower side piece of the negative sheet is kept bent downward by the fifth guide plate. An opening is opened between the upper end piece and the lower end piece to facilitate taking out the negative film to guide it to the negative carrier (printing frame) through the take-out position regulating part.

The present invention will be specifically described below with reference to Examples.

FIG. 1 shows a composite body 1 of a flexible transparent band 4 wound into a roll and a negative sheet 2 containing a shortened negative film 3 used in the present invention. The film insertion/removal portions of the negative sheet 2 containing the negative film 3 are sequentially arranged along the longitudinal edge 4' of the film 4, slightly inside thereof.
It is fixed to a flexible transparent band 4. Each of the set of negative sheets 2 has a plurality of bag portions, and the negative film 3 is housed therein. Negative film insertion/extraction port upper piece 2 of negative sheet 2
A is a flexible transparent band 4 made of, for example, double-sided tape.
It is attached to. Alternatively, a single-sided tape may be used between two adjacent sets of negative sheets to connect and fix them across the gap between the two sets of negative sheets. However, it is not necessary to connect the pieces 2B and 2B' of the two sets of negative sheets below the negative film insertion/extraction opening with tape.

As the flexible transparent strip used in the present invention, it is preferable to use a material that can withstand repeated bending of the edges, such as polyester film, but other plastic films can also be used. It is preferable that the negative sheet has one side piece longer than the other at the end of the negative film insertion/take-out opening, but other shapes can also be used, and in either case, a flexible transparent strip is used. The edge of the film must be bent so that when one film follows the other film, the other film remains, for example, the negative film insertion/ejection openings must be separated. . Therefore, apply some force to the vicinity of the insertion/extraction port of the heat-welded part for forming the bag part of the negative sheet to separate them from each other to form the upper part 2A and the lower part 2B, giving each part a degree of freedom. .

FIG. 2 is a schematic diagram of an apparatus for carrying out the method according to the present invention, in which a composite body 1 of a negative sheet containing a negative film and a flexible transparent band to which it is fixed is conveyed. At this time, the flexible transparent band is wound around the negative sheet supply magazine section 5 so as to be above the negative sheet. The composite 1 is sent out from the supply magazine section 5, passes through a dancer roller 18, a guide roller 19, and is conveyed by a drive roller 7 in the direction of arrow A. 8 is a fixed roller, 9 is a negative take-out position regulating section, and 10 is a negative sheet winding magazine section. A negative film transport path 11 extends perpendicularly to the paper surface and is connected to a negative carrier (printing frame), not shown. When the negative film to be printed reaches the negative take-out position (based on information given in advance to a detector (not shown))
The conveyance of the composite 1 is stopped, and the negative film is guided to the negative film conveyance path.

In the present invention, the first guide plate 12, the second guide plate 13, the direction change roller 14, the third guide plate 15, the fourth guide plate 16, and the fifth The method and apparatus are characterized in that the combination of guide plates 17 makes it easy to take out the negative film from the negative sheet.

The first guide plate 12 is provided substantially parallel to the conveyance table above a position facing the side edge of the conveyance table 6, and extends in the conveyance direction between the second guide plate 13 and the fourth guide plate. . The second guide plate 13 is installed substantially below the first guide plate 12 to face the side edge of the conveyor table 6, and is attached to the flexible transparent strip 4 shown in FIG. Upper side piece 2 of the negative sheet
The negative film 3 and the negative sheet lower side piece 2B are separated from the integral part A. That is, the end of the flexible transparent strip 4 and the upper side of the negative sheet 2A are bent upward by the first guide plate, and the end of the negative film 3 and the lower side of the negative sheet 2B are bent upward by the second guide plate 13.
As a result, it bends downward and flexes into the gap between the edge of the conveyor table and the second guide plate 13. Second guide plate 13
has such a shape that the end of the negative film 3 and the lower side piece 2B of the negative sheet gradually bend downward as the composite 1 is conveyed.

The direction change roller 14 is installed at a position adjacent to the second guide plate 13 on the downstream side of the second guide plate 13 in the conveyance direction and facing the side edge of the conveyance table 6 . The direction changing roller 14 integrally separates the lower side piece 2B of the negative sheet 2 and the end of the negative film 3 from the integrated body of the flexible transparent band 4 and the upper side piece 2A of the negative film, and rotates the negative film 3. It leads from the negative take-out position regulating section 9 to the negative film transport path 11.

As shown in FIG.
is fixed at one end to the conveyor table 6 with its axis at an angle α toward the conveyor table, and the lower side piece 2B of the negative sheet and the end of the negative film 3 are located in the gap between the conveyor table 6 and the direction change roller 14. bent inward, while
The ends of the upper side piece 2A of the negative sheet and the flexible transparent strip 4 are kept bent upward by the first guide plate 12.

A third guide plate 15 and a fourth guide plate 16 are installed downstream of the direction change roller 14. The third guide plate has its most upstream end separated from the direction change roller 14 by a distance equal to or more than the width of at least one negative film (35 mm), and its most downstream end restricted to the negative take-out position. It extends to section 9. The most upstream end position of the third guide plate 15 is located at a position lower than the end position of the negative film 3 bent downward by the direction change roller 14, and the height gradually increases toward the downstream direction. It is an inclined surface 15', and the negative ejection position regulating part 9
Nearby, a horizontal surface 15'' is formed so as to be flush with the negative film take-out position, and the negative film passes over the upper surface thereof and is guided to the negative take-out position regulating section.

The fourth guide plate 16 extends from the vicinity immediately downstream of the direction change roller 14 to just before the negative take-out position regulating section 9, and its height is below the first guide plate 7 and above the composite being conveyed. This prevents the end of the negative film released from the direction changing roller 14 from bending upward due to the elastic force.

The fifth guide plate 17 is provided on the conveyance platform 6 side, substantially facing the third guide plate 15, and maintains the downward bending of the negative sheet lower side piece 2B. That is,
The lower end side piece 2B of the negative sheet is maintained bent in the gap between the third guide plate 15 and the fifth guide plate 17. This state is shown in FIG. Here, reference numeral 20 denotes a sixth guide plate located at the same height as the first guide plate 12 provided in the negative take-out insertion section 21 located near the negative take-out position regulating section 9.

The effects of the above configuration will be explained in more detail.

First, by manual operation, the flexible transparent band 4 and the negative sheet upper side piece 2A fixed to it are attached to the first
The negative film 3 and the negative sheet lower side piece 2B are separated from each other so as to be bent above the guide plate 12.
By conveying the composite body 1 in the direction of arrow A, the end portion of the negative film 3 and the lower side piece 2B of the negative sheet are transferred to the second
The guide plate 13 bends the second guide plate 13 downward between it and the conveyance table 6. The end of the negative film 3 and the lower side piece 2B of the negative sheet, which are bent downward as the composite 1 is conveyed, are moved by the direction changing roll 1.
Pass 4. The situation is shown in FIG. Since the direction changing roll 14 and the end of the negative film 3 are in almost line contact, the negative film 3 is less likely to be damaged. By the direction changing roll 14, the edge of the negative film and the lower side piece of the negative sheet are
Forced in the desired direction. Immediately after the negative film end and the negative sheet lower side piece 2B pass the direction change roll, the distance between the direction change roll 14 and the most upstream end of the third guide plate 15 is longer than the width of the film. The edge of the film is not subject to any restrictions and returns to the horizontal direction due to its own elastic force. At this time, since the upstream side of the negative sheet lower side piece 2B is bent downward by the direction change roller 14, the negative film 3 returns to the horizontal position.
The downward bending of the negative sheet lower side piece 2B at the position corresponding to the end of the negative sheet is maintained. In other words, the force of the negative film 3 as an elastic body to return upward is greater than that of the negative sheet lower side piece 2B.

The end of the negative film 3 released from the direction changing roller 14 springs up toward the fourth guide plate 16 due to its own elastic force. The fourth guide plate is
This prevents excessive rebound of the end portion of the negative film 3, and is particularly effective when the negative film 3 itself has a tendency to curl upward.

As the composite 1 is conveyed, the end of the negative film 3 passes above the third guide plate 15. As mentioned above, when the end of the negative film 3 is released from the direction changing roll 14, due to its own elastic force,
Although the negative film 3 is placed in the restored position in the horizontal direction, if the negative film 3 itself has a tendency to curl downward, there is a possibility that the restoration will not be performed satisfactorily. Since the most upstream end of the third guide plate 15 is located at a lower position than the lowermost end of the downwardly bent negative film 3, even if the negative film has a tendency to curl downward, the third guide plate 15 It becomes possible to be guided onto the inclined surface of the third guide plate and onto the horizontal surface of the third guide plate. At this time, the lower side piece 2B of the negative sheet has the third guide plate 15 and the fifth guide plate 17.
During the downward flexion is maintained. The end portion of the flexible transparent band 4 and the upper side piece 2A of the negative sheet are bent upward by the relatively long first guide plate 12, and even after passing through the first guide plate 12, the upper side piece 2A of the negative sheet is bent upward. The bend in the upstream section is propagated. In this embodiment, the first guide plate 1 is attached to the negative extraction position regulating section 9.
2, a sixth guide plate 20 is provided at the same height as the end of the flexible transparent band 4 and the upper side piece 2A of the negative sheet.
In the negative take-out position regulating section 9, the upper side piece 2A of the negative sheet and the lower side piece 2B are completely separated and opened, and after the negative film take-out and printing operations are completed. This makes it easy to insert negative film.

In addition, in the present invention, a plurality of rollers may be arranged in parallel instead of the second guide plate 13, and the positional relationship and shape of each guide plate and the direction changing roller are determined by the negative take-out position regulating section. In this case, any method may be used as long as the upper side piece and the lower side piece of the negative sheet are separated and an opening is provided between them. Furthermore, it goes without saying that the technical idea of the present invention is not limited to the above-described embodiments, but extends to various modifications within the scope of the claims.
