Description

[Detailed Description of the Invention] The present invention relates to a holder used for printing and developing photographs.

The conventional holder used for printing and developing photographs is a thin bag-shaped holder body made of an opaque material with an opening at one end and a chamber inside, with edges on all sides. A window was formed so as to have a window, a lid plate was inserted into the room through the opening, and the photosensitive paper was inserted through the opening along the back side of the lid plate to be placed inside the room.

However, when printing and developing photographs, the cover plate was taken in and out without being removed from the holder body, and the window in the holder body was opened to expose the photosensitive paper. When most of the plate is pulled out of the holder body, the cover plate may end up coming out of the holder body.
Another drawback is that the photosensitive paper is pulled out from the bag while it is stuck to the back side of the lid plate. In particular, the lid plate and photosensitive paper are
If the fixer fluid, water, etc. leaked, the photosensitive paper would be pulled out even more.

Furthermore, when the tip of the cover plate is inserted into the holder body, the tip often gets caught on the front edge of the top plate of the holder body, making it difficult to insert the cover plate into the specified position in the holder body. There were various drawbacks such as the light rays that entered the inside of the holder from the opening of the holder body entered between the cover plate and the photosensitive paper and exposed the photosensitive paper. It is.

The present invention improves the above deficiencies, and includes:
The purpose of this is to fix the photosensitive paper so that it does not move inside the holder body, so that when the cover plate is pulled, the photosensitive paper will not come out from the opening of the holder body, and also to prevent the photosensitive paper from coming out from the opening of the holder body when the cover plate is pulled. By forming a bent part at the tip of the holder body, the tip of the cover plate can be smoothly inserted into a predetermined position without getting caught on the front edge of the top plate of the holder body, Furthermore, by providing the first and second light-shielding plates at the opening of the holder body, light rays are prevented from entering the room through the opening, thereby preventing photosensitive paper from being exposed. To provide a holder for development processing.

That is, the present invention has a top plate of a thin bag-shaped holder body made of an opaque material with a mouth at one end and a chamber inside.
A window is formed so as to have edges on all sides, and a first light-shielding plate provided on the top plate is extended outward from the mouth, and the first light-shielding plate is bent into the room from the mouth and extended outward from the mouth. Then, bend the second light shielding plate provided on the back plate into the room from the mouth part, and make left and right cut lines on the left and right ends of the second light shielding plate in the same direction as the bending direction of the second light shielding plate. , with left and right claw pieces formed at the left and right outer edges, and a bendable presser piece formed at the center thereof, and the rear end of the photosensitive paper introduced into the chamber from the mouth placed on the left and right claw pieces.
In addition, a thin cover plate made of an opaque material with a presser piece placed on the rear end, the tip of which is bent toward the rear surface to form a folded piece, and the entire surface of the photosensitive paper inserted into the chamber from the opening. This invention relates to a holder for printing and developing photographs, which covers the cover plate, and the rear part of the cover plate projects outward from the opening. That's right.

The thin bag-shaped holder main body 3 of the present invention is made of an opaque material made of synthetic resin or paper, and is somewhat hard and somewhat elastic. A mouth portion 1 is provided at one end, and a chamber 2 is provided inside. Further, a window portion 5 is formed on the top plate 3a of the holder body 3 so as to have edges 4 on all sides.
A first light shielding plate 6 provided on the top plate 3a and extending outward from the mouth 1 is bent into the chamber 2 from the mouth 1 portion. Further, a second light shielding plate 7 provided on the back plate 3b and extending outward from the opening 1 is also bent into the chamber 2 from the opening 1 portion.

Left and right cut lines 8 are formed on the left and right parts of the tip of the second light shielding plate 7 in the same direction as the bending direction of the second light shielding plate 7.
a, 8b are provided, and left and right claw pieces 9a, 9b are formed at the left and right outer ends of the left and right cutting lines 8a, 8b, and
The base points 8c and 8d of the left and right scoring lines 8a and 8b are connected by a bending line 10, and a presser piece 11 is formed in a portion surrounded by the left and right scoring lines 8a and 8b and the bending line 10. .

The photosensitive paper 12 is inserted into the chamber 2 through the opening 1. In this case, the presser piece 11 is placed along the bending line 1.
If the photosensitive paper 12 is bent from 0 toward the opening 1 and put into the chamber 2 in this state, and the leading end 12a of the photosensitive paper 12 comes into contact with the inner part 2a of the chamber 2,
The rear end 12b of the photosensitive paper 12 is attached to the left and right claw pieces 9.
It is placed on a and 9b. Next, the presser piece 11 is bent along the bending line 10 toward the inner part 2a of the chamber 2, and the presser piece 11 is placed on the rear end portion 12a.
Therefore, the rear end 12b of the photosensitive paper 12 is held between the left and right claw pieces 9a, 9b and the presser piece 11, and the leading end 12a of the photosensitive paper 12 is in the inner part 2 of the chamber 2.
Since it is in contact with a, the photosensitive paper 12 is fixed in place within the chamber 2 so as not to move, and the photosensitive paper 12 can be fixed in the chamber 2 with a simple operation.

The thin cover plate 13 is made of an opaque material made of synthetic resin or paper, and is somewhat hard and somewhat elastic, and its tip 13a is bent toward the rear surface to form a bent piece 13b. The cover plate 13 is inserted into the chamber 2 through the opening 1 to cover the entire surface of the photosensitive paper 12, and the rear portion 13c of the cover plate 13 projects outward from the opening 1.

In the present invention, the holder body 3 is loaded into a dark case and a photo is printed on the photosensitive paper 12 placed inside the chamber 2, and then the holder body 3 is placed in a developing tank.
The holder body 3 is placed into a washing tank and a fixing tank one after another for development processing. The surface of the photosensitive paper 12 is exposed to the window 5 of the holder main body 3 by opening or closing the window 5, or the entire surface of the photosensitive paper 12 is covered with the cover plate 13 for printing and development processing. It is something to do.

Therefore, when the cover plate 13 is pulled out, the cover plate 1
3 is bent toward the rear surface to form a bent piece 13b, so that the bent piece 13b
Since the tip 13a of the holder body 3 hits the tip 6a of the first light shielding plate 6 and the cover plate 13 is stopped, the entire cover plate 13 is not pulled out from the opening 1 of the holder body 3. do not have.

There is a photosensitive paper 12 on the back surface of the cover plate 13, and the rear end 12b of the photosensitive paper 12 is connected to the right and left claw pieces 9a, 9b at the left and right outer ends of the tip of the second light shielding plate 7, The leading end 12a of the photosensitive paper 12 is held by a certain presser piece 11, and the leading end 12a of the photosensitive paper 12 is placed in the inner part 2 of the chamber 2.
Since it is in contact with a, the photosensitive paper 12 is fixed in place within the chamber 2 so as not to move. Therefore, when the cover plate 13 is pulled out in the direction of the opening 1, there is no possibility that the photosensitive paper 12 stuck to the cover plate 13 will be pulled out.

In addition, in the present invention, as described above, the lid plate 13
Bend the tip 13a to the rear surface to form the bent piece 1.
3b, when the cover plate 13 is inserted into the holder main body 3, the bent portion 13d of the bent piece 13b does not catch on the front edge 4 of the top plate 3a. Place the cover plate 13 on the holder body 3
can be smoothly inserted into the designated position.

In addition, in the present invention, a first holder is provided on the top plate 3a extending outward from the opening 1 at one end of the holder main body 3.
The light shielding plate 6 was bent into the chamber 2 from the mouth part 1, and the second light shielding plate 7, which was extended outward from the mouth part 1 and provided on the back plate 3b, was bent into the chamber 2 from the mouth part 1. Moreover, since the first light-shielding plate 6 and the second light-shielding plate 7 have some elasticity, they come into close contact with the front and back surfaces of the lid plate 13, and therefore, the inside of the chamber 2 is more secure than the opening 1. If so, the light rays will not enter between the back surface of the cover plate 13 and the photosensitive paper 12, so
This has the effect of preventing the photosensitive paper 12 from being exposed to light.
