Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film containing petrone for cameras such as 35 mm and Broni.

[0002]

2. Description of the Related Art A 35 mm, film containing PETRONE for a camera such as a brownie has a leader portion for fixing the film to a take-up spool of the camera at a tip portion. Width of the tip of 22
A leader portion formed into a substantially rectangular shape with a millimeter length of about 30 millimeters is formed. Conventionally, in these films, the unused product before shooting and the used product after shooting are the same in appearance, and it is determined whether the film is unused or used by opening the cosmetic box of the film.

[0003]

[Problems to be Solved by the Invention] It is impossible to determine whether the film in a petrone shape that is opened from the case and taken out of the case is unused or used by appearance, so that the petrone film remains mixed. In some cases, a used film was accidentally set in the camera and double shooting was performed, or conversely, an unused film was developed and wasted.

[0004]

For this onset bright SUMMARY OF THE INVENTION To solve the above problems, it provided a break in the film leader portion, the cutting
The outer part of the eye is the separation part, and the inner part is the leader part.
Can be set in the camera with the separated parts separated along
It has a separate part at the tip of the film.
When it exists, a mark indicating "unused" is displayed,
When the separation part is separated, the mark of "use"
Includes a Petrone for the camera that is configured to remain only
It provides a film .

[0005]

The function of the film containing a petrone for a camera of the present invention is as follows:
If there is a separation part, it can be set in the camera.
Is not possible and is an "unused"
Is displayed, so the user can be sure that this film
Can be found to be unused. This file
When setting the Rum on the camera, separate it along the cut line.
The parts may be separated so that the leader part remains. This
At this time, only the "used" mark remains on the film
Shown. Therefore, the film taken out from the camera after shooting
Film, that is, used film, remains in the leader section only.
User, and only the "used" mark is displayed.
Certainly knows that this film is used
be able to.

As described above, the Petrone for camera of the present invention
With the film, it is extremely clear to distinguish unused and used products.
Be certain. In addition, a structure with a cut at the tip of the film
Since it is built, it is necessary to use a separate label etc.
There is no cost, there is no cost advantage,
Make sure there is no problem and distinguish between "unused" and "used"
be able to.

EXAMPLE An example in which the present invention is applied to a 35 mm film will be described below.

FIG. 1 shows a first embodiment. The tip of the film 1 has an uneven curved cut, as shown in FIG.
As shown by a double line, the convex part of the curve is a completely cut line 2, and the concave part of the curve shown by a single line in FIG.
There is a half cut 3 formed by a kerf having a thickness of about 1/2. The film 1 has a perforation with a diameter of 0.3 to 0.5 mm as the mark 6, and "not yet" on the side of the separable separation part 4 of the film 1 across the cut, and the remaining side which should be the leader part 5 of the film 1. Has three letters "use" at equal intervals. The mark 6 may be "UNUSED" in English as shown in FIG. Reference numeral 8 is a perforation hole for hanging the film on the teeth of the sprout.

When this film 1 is used, the leader portion 5 as shown in FIG. 5 is formed by separating and separating the separation portion 4 upward and the leader portion 5 downward as shown in FIG. , Set it on the take-up spool of the camera and use it.

FIG. 6 shows a second embodiment which makes use of the conventional film prototype. In this case, the perforation 3a allows the separation part 4 and the leader part 5 to be separated .
The "not" in the separation portion 4 side as in the first embodiment, Ru Tei placed perforations characters and the like of "use" the leader portion 5 side.
The method of separating the film is the same as in the first embodiment.

[0011]

Since the present invention has the above-mentioned structure, it has the following special actions and effects.

Since the separable part of the tip of the film is removed during use, the shapes of the unused film and the used film are different, and at this time, the "unused" part of the mark indicating "unused" should be removed. As a result, not only the shape but also the display changes, and unused products can be easily and clearly identified.As a result, erroneous development of unused PETRONE-containing film and double shooting of used products can be prevented. can do.

The difference in the shape of the film tip between the unused film and the used product can be identified by touching, so that it can be easily identified even in a dark place, and it is possible to prevent the unused film from being accidentally developed. It is very convenient because you can do it.

A cut at the leading edge of the film , “not yet”,
It's a simple process to put a mark such as "use"
Since the product of the present invention can be formed by
Can be manufactured. Also, the combined state of the leader part and the separated part is different.
Stronger than when sticking a body identification tag on a film, etc.
Can be defined as "unused" or "used"
Can be done reliably .

As a result of being able to easily discriminate unused products in the form of Petrone, it is not necessary to carry a case or the like into which unused products of film and used products are separately sorted, and the number of portable products can be reduced. Because especially when traveling,
It is convenient for mountaineering.
