DETAILED DESCRIPTION OF THE INVENTION The present invention provides a process for reorder printing, etc., in which negative film cut into short lengths for several frames is stored in a negative film storage bag (hereinafter referred to as "negative sheet"). This invention relates to how to handle negative film when it is submitted to

The developed negative film is cut into short lengths of several frames and returned to the customer on negative sheets.
Reorders (orders for extra prints) are made at the laboratory using the negative film still in the negative sheet and an order form with specified items such as the specified number of the negative frame, finished screen size, paper type, number of prints, etc. is requested. At the laboratory, the specified number written on the order form is compared with the side print number of the negative film, and the data regarding the reordered negative frame is input into the recording medium, and the negative frame is supplied to the printer at the time of printing. At this time, data is sequentially output from the recording medium, and printing is performed based on this data.

The handling of negative film for such re-order printing, etc. is as follows: (1) Taking out the negative film contained in the negative sheet and splicing them to make them long and handling them; (2) Japanese Patent Application Laid-Open No. 131717/1983 As disclosed, a method of handling a shortened negative film by sequentially sandwiching it in the longitudinal direction between two flexible transparent strips to lengthen the film; (3) removing the negative film from a negative sheet; There is a method in which a negative film is subjected to printing and then returned to a negative sheet, and the present invention relates to an improvement on method (3) above.

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 which opens a negative film insertion/removal port of a negative sheet, takes out the negative film, subjects it to printing, and returns it 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 that the negative sheets are successively pasted onto a roll-shaped strip having a recording body so that the negative film is at right angles. A method is proposed.

An object of the present invention is to fix and fix negative sheets to a roll-shaped strip in sequence.
It is an object of the present invention to provide a negative film handling method for facilitating removal and handling of a flexible transparent strip.

The present invention has been made to achieve the above-mentioned object, and the present invention has been made in order to align a negative sheet containing a negative film with the insertion/ejection opening sides of the negative film accommodated in the negative sheet, and to align the negative film insertion/ejection opening side.
In a negative film handling method in which the negative film is sequentially arranged and fixed on a flexible transparent strip in a direction perpendicular to the take-out direction, holes are formed in the flexible transparent strip;
The present invention is characterized in that a reusable adhesive tape is previously adhered to the flexible transparent band from one side of the hole, and a negative sheet is adhered to the adhesive tape from the other side through the hole, thereby fixing the negative sheet.

Therefore, in the present invention, the negative sheet can be fixed to the flexible transparent band simply by pressing the negative sheet into the hole of the flexible transparent band, and after processing the negative film, the negative film can be easily attached to the flexible transparent band. It can be separated from the body. To securely fix a negative sheet to prevent the negative sheet from falling off a flexible transparent band during processing of the negative film, and to easily and easily remove the negative sheet from the flexible transparent band after processing the negative film. In order to achieve this, the number and size of holes formed in the flexible band may be adjusted.

As the flexible transparent band used in the present invention, it is preferable to use a material that can withstand repeated rolling, unwinding, and pulling out, such as polyester film, but other materials may be used. Plastic film can be used. Insert the negative film into the negative sheet.
It is preferable that one piece of the end side piece of the outlet, that is, the side that is fixed to the flexible transparent band, is longer than the other piece, but other shapes can also be used, and in either case. The shape may be such that when one side piece is fixed to the flexible transparent band, the other side piece is not fixed.

Hereinafter, the present invention will be specifically described with reference to examples.

FIG. 1 shows a state in which a negative sheet 3 containing a shortened negative film 1 housed in a storage section 2 is fixed to a flexible transparent strip 5 having holes 4 with an adhesive tape 6 through the holes 4. FIG. 2 is a cross-sectional view of the negative sheet 3, and the negative sheet 3 has a pocket-shaped accommodating part 2 for accommodating each negative film 1 separately, and a pocket-shaped accommodating part 2 for accommodating each negative film 1 separately, and a pocket-shaped accommodating part 2 for easily inserting and taking out the negative film 1 into the accommodating part 2. The negative sheet 3 is made up of end side pieces 7A and 7B, and the negative film insertion/take-out opening 8 side is along one edge 9 of the flexible transparent strip 5, that is, the negative film insertion/take-out direction. They are arranged and fastened in order in the direction perpendicular to . The holes 4 are formed continuously along the longitudinal direction of the flexible transparent strip 5, and the adhesive tape 6 is pasted facing the holes 4, so that the negative sheet 3 is inserted through the holes 4. It is fixed to the adhesive tape 6 of the part. Negative film 1
is generally cut into 6-frame pieces, but in the case of an irregular number of frames, it is shorter than this, and negative film 1A is cut into 3-frame pieces, and in this case, the applicant of the present invention Patent application filed earlier: 1972-45415
As proposed in the above, a stopper section 10 is formed in the negative film insertion path of the storage section 2 and the negative film is stored therein. The flexible transparent band 4 to which the negative sheets 3 are sequentially attached in this manner can be rolled up and handled as a roll. In order to open the negative film insertion/take-out port 8 of the negative sheet 3, as shown in the sectional view in FIG.
This can be done by blowing gas from a direction or by suctioning the end side piece 7B under reduced pressure in the direction B as shown in the cross-sectional view in FIG. 4, thereby bending the end side piece 7B. This can also be done by bending the edge 9 of the flexible transparent band 5 as shown in the cross-sectional view in FIG. 5, and furthermore, as shown in the cross-sectional view in FIG. It is also possible to bend the end side piece 7B by spraying or suctioning under reduced pressure in the direction of arrow B. Such openings can be made using conventional means when the flexible transparent strip 5 is unwound and transported longitudinally.

When the negative film 1 is opened to the states shown in FIGS. 3 and 4, the negative film 1 can be taken out from the negative sheet 3 by using a suction cup or by using a roller. When opened to the states shown in FIGS. 5 and 6, the negative film 1 can be pinched and picked out in addition to the method described above. Insertion of the negative film 1 into the negative sheet 3 can be carried out in a similar manner. Then, in order to sequentially stop the flexible transparent band 5 to which the negative sheet 3 is attached while feeding it in the longitudinal direction, it is necessary to sequentially stop the flexible transparent band 5 to which the negative film 1 is inserted and taken out. This can be done by placing a mark at a predetermined position and detecting this mark to control the feeding mechanism.

To attach the negative sheet 3 to the flexible transparent strip 5, first attach an adhesive tape 6 along the holes 4, and then line up the negative sheet 3 on the opposite side of the adhesive tape 6 with the part opposite to the hole 4. This can be done by pressing.
This fixing can be carried out by rolling the flexible transparent band 5 to which the adhesive tape 6 is attached, and sequentially fixing the negative sheets while unrolling the roll.

After the negative sheet 3 has been used for reorder printing, it can be reliably removed from the adhesive tape by peeling it off from the flexible transparent band 5, and the flexible transparent band 5 from which the negative sheet 3 has been removed can be rolled up. Even when handled as a roll, the flexible transparent strip 5 and the adhesive surfaces of the adhesive tape 6 do not stick to each other, and can be immediately used for fixing a negative sheet again.

In order to adhere the adhesive tape 6 to the flexible transparent strip 5 in advance, especially when the adhesive tape 6 is to be attached along the longitudinal direction, a roll of the adhesive tape 6 and a roll of the flexible transparent strip 5 are bonded. It is also easily possible to perform this by a mechanical means of unwinding each roll and sending it out.

As shown in the embodiments of FIGS. 1 and 2,
If the hole 4 is provided at a position facing the end side piece 7A, the end side piece 7A will not be exposed to the flexible transparent strip 5 when the opening method shown in FIGS. 2 to 5 is performed. This is convenient because it is fixed to. By providing the holes 4 continuously along the end side piece 7A, the flexible transparent strip 5 can be easily bent when performing the opening method shown in FIGS. 4 and 5. I can do it.

In the above embodiment, the adhesive tape 6 is placed along the longitudinal direction of the flexible transparent strip 5, but
They may also be aligned in orthogonal directions.

As described above, the present invention is a negative film handling method in which a negative sheet is fixed with an adhesive tape through a hole made in a flexible transparent band, so it is possible to attach and remove the negative sheet and handle the flexible transparent band. can be facilitated.
