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 discloses a method in which the negative sheets are successively pasted onto a roll-shaped band 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 negative film handling device that facilitates the insertion and removal of negative films in a manner 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.

In order to achieve the above-mentioned object of the present invention, a negative film to be printed reaches near the entrance of a negative film transport path, a negative film ejection/insertion port of a negative sheet is opened, and an end of the negative film is moved from the ejection/insertion port. In the state in which the negative film is projected in the direction of the negative film transport path, the ends of the negative film are aligned in a direction parallel to the negative film transport path and the longitudinal center of the negative film is aligned with the longitudinal center of the transport path. The negative film is taken out from the negative sheet through a negative film end alignment regulating means, and is conveyed on a negative film conveyance path to a negative carrier. After printing is completed, the negative film is conveyed on a negative film conveyance path to The device is characterized in that it includes a negative film ejecting/inserting means for inserting the negative film into the film.

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. Film insertion/extraction portions for negative sheets 2 containing negative films 3 are arranged in sequence along the longitudinal edge 4' of the film 4, and fixedly attached to the flexible transparent band 4. Each set of negative sheets 2 has a plurality of bag portions,
A negative film 3 is housed therein.
The upper piece 2A of the negative film insertion/ejection opening of the negative sheet 2 is fixed to the flexible transparent band 4 with, for example, double-sided tape. 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. For example, the end pieces of the negative film insertion/ejection opening must be separated so that when one piece follows the edge of the film, the other piece remains without following. Therefore, the upper piece 2 is separated from each other by applying a slight force to the vicinity of the insertion/extraction opening of the heat-sealed part for forming the bag part of the negative sheet.
A and the lower part 2B are formed to give each a degree of freedom.
