Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is a photographic film drawer used to pull out film from a cartridge.

[Prior Art] When setting photographic film in a developing device that does not require a darkroom, or when developing photographic film in a cartridge whose lid is difficult to remove, it is necessary to pull out the leading edge of the film from the cartridge. Dedicated equipment is installed in developing laboratories that handle large quantities of photographic film, but it is large and expensive, and not every average photography enthusiast can afford to have one. For this reason, a device as shown in FIG. 4 is known as one that can be used even by general photography enthusiasts. In the same figure, the guide plate 12, the scissor plate 13, and the film holding plate 14 of the film drawer 11 are inserted into the cartridge 15, and the film is placed between the guide plates 12 and 14.
After pinching and holding the film with the scissors plate 13, the film drawer is pulled to the right and the film is drawn out from the cartridge 15.

[Problems to be Solved by the Invention] The above-described conventional film drawer 11 has a problem in that its structure is not necessarily simple, and its operation is not necessarily easy.

This invention was devised to solve these problems, and the object is to provide a photographic film drawer that is simple in construction and easy to operate.

[Means for Solving the Problems] The photographic film drawer of this invention is in the form of an elastic strip having an adhesive surface coated with an adhesive, and allows the film to be attached to the adhesive surface and removed from the cartridge. an insertion plate whose tip can be inserted into the cartridge from between the telescopes in order to pull it out; and an insertion plate that is removably affixed to the adhesive surface to cover the adhesive surface so that the insertion plate can be inserted into the cartridge; The present invention is characterized in that it includes a flexible, non-adhesive peeling tape having a folded part that is folded back at the tip of the insertion plate to enable the peeling.

[Function] The photographic film puller is constructed in this way,
To pull out the film from the cartridge, insert the tip of the insertion plate into the cartridge for an appropriate length between the tapes of the cartridge, then rotate the spool of the cartridge so that the end of the film inside the cartridge is aligned with the insertion plate. After adjusting the position, pull the folded part of the release tape on the pull-out tool and pull it out from the cartridge. When such a pull-out operation is performed, the release tape is peeled off from the folding point of the tip of the insertion plate, the adhesive surface of the insertion plate is exposed, and the film adheres to this adhesive surface. When the film sticks to the adhesive surface, pull the drawer and pull out the insertion board from the cartridge. Since the film is stuck to the adhesive surface of the insertion board, the film will also be pulled out from the cartridge.

[Embodiment] An embodiment of this invention will be described below with reference to the drawings. FIG. 1 is an enlarged side view for explaining one embodiment of this invention, and FIG. 2 is a perspective view of the same embodiment. In FIGS. 1 and 2, reference numeral 1 denotes an elastic, elongated, rectangular insertion plate, one surface of which forms an adhesive surface 1a coated with adhesive. This adhesive surface 1a is covered with a non-adhesive release tape 2 which has a smooth surface and which makes it difficult for the adhesive to transfer to this surface.
is pasted using the adhesive strength of the adhesive to the adhesive side 1.
The release tape 2 is further provided with a folded portion 2a which is folded back at the tip 1b of the insertion plate 1 to facilitate peeling off the release tape 2 from the adhesive surface 1a.

FIG. 3 is a partial cross-sectional view for explaining the operation of pulling out a film from a cartridge using the photographic film drawer constructed as described above. To pull out film 4 from patrone 3,
As shown in the figure, the tip 1b of the insertion plate 1 is inserted by about several centimeters between the telescopes 3a of the cartridge 3. This insertion operation can be easily performed without resistance since the adhesive surface 1a of the insertion plate 1 is covered with the release tape 2.

After the above-mentioned insertion operation is completed, the film 4 is moved to a position where its terminal end overlaps the adhesive surface 1a near the tip 1b of the insertion plate 1. For example, this operation involves holding the spool 3b of the cartridge 3. If you rotate it counterclockwise on the same diagram, film 4
The film 4 moves as if being wound around the spool 3b, but when the end of the film 4 passes the position of the telescope 3a, it makes a faint sound. By this sound, it is detected that the end of the film 4 has come under the insertion plate 1, the rotation of the spool 3b is stopped, and the folded part 2a of the release tape 2 is pulled to the right in the figure. Stretch it and peel it off from the adhesive surface 1a. As mentioned above, since the release tape 2 is non-adhesive, it can be easily attached to the adhesive surface 1a.
Since it is more removable and the adhesive does not transfer to the release tape 2, it is possible to pull out the space between the telescopes 3a without resistance. When the release tape 2 is peeled off, the adhesive surface 1a is exposed and sticks the film 4 to the insertion plate 1, allowing the film 4 to be pulled out.
In this state, when the insertion plate 1 is pulled out to the right in the figure, the terminal end of the film 4 is also pulled out from between the telescopes 3a of the cartridge 3.

In addition, the terminal end of the film 4 is connected to the tip 1 of the insertion plate 1.
Another way to match it near b is to set spool 3
There is also a positioning method in which the end portion of the film 4 is stopped at the position of the telescope 3a by rotating the film 4 clockwise in the figure. According to this method, the film 4 can be attached to the adhesive surface 1a of the insertion plate 1 facing inward of the cartridge 3 in the same way as in the above-mentioned method. It is also possible to insert the film 4 in the outward direction, that is, with the vertical relationship reversed from that shown in FIG. can.

The photographic film puller according to this invention can be used repeatedly by reapplying the release tape to the adhesive surface of the original insertion plate after pulling out the film. Also, if the adhesive strength of the adhesive becomes weak, you can cut off this part and use it for an even longer period of time.

Note that this invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without changing the gist. For example, it is also possible to provide adhesive surfaces on both sides of the insertion plate and attach a film to either side.

[Effects of the invention] According to this invention, it is possible to provide a photographic film drawer that is extremely simple in structure, inexpensive, and easy to operate.
