JPH03263036A - Film-housing container and method for checking used state of film - Google Patents

Abstract

PURPOSE:To obtain the film housing container which allows the checking of the used state of a film by providing a checking member which allows the checking of the used state of the film from the state change of the member on the film-housing container. CONSTITUTION:The checking member 4 which allows the checking of the used state of the film from the state change of the film is provided on the film- housing container 1. The checking member 4, therefore, induces the state change (for example, attains a cut or broken state, etc.). Whether the film is unphotographed or already photographed can be identified by viewing the checking member 4 when the film-housing container is loaded into a camera with automatic winding. The film-housing container 1 which allows the checking of the used state of the films obtd. in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a film storage container for storing photographic film and a method for confirming that the film is used.

(Prior Art) Conventional film storage containers such as cartridges in which photographic film itself is wound and stored, sealed containers made of synthetic resin for storing photographic films, or outer boxes that can accommodate the sealed containers However, it was difficult to confirm the used state of the film just by observing the state of the film itself.

In recent years, various types of camera machines (hereinafter also referred to as automatic winding cameras) have been commercialized that automatically wind up the film that has already been photographed (hereinafter also simply referred to as already-shot film) after a specified number of photographs have been taken.

These automatic winding cameras have a system that collects all of the film in a cartridge that directly winds and stores unshot film and film that has already been filmed, or leaves the edge of the film on the outside of the cartridge. There is a method to collect it.

(Problems to be Solved by the Invention) However, especially in the latter case, it is impossible to distinguish between unphotographed film and photographed film, and a problem arises in that the unphotographed film is developed in the developing engine.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and aims to provide a film storage container and a method for confirming whether a film is used or not.

[Configuration of the Invention (Means for Solving the Problems) The configuration of the present invention for achieving the above object is that, in a film storage container for storing photographic film, a member is used to store the used film in the film storage container. The film storage container is characterized by being provided with a confirmation member that can be confirmed by a change in the state of the film, and the film storage container may be a cartridge in which the photographic film itself is wound and stored, a sealed container made of synthetic resin that stores the photographic film, or The present invention is characterized in that it is any one of the outer boxes capable of accommodating the sealed container or a combination thereof, and further characterized in that the confirmation member is an adhesive thin film seal.

The method for confirming whether the photographic film is used is characterized in that the used state of the photographic film is confirmed by a change in the state of a confirmation member provided on a film storage container in which the photographic film is stored.

(for production) The operation of the present invention having the above configuration will be explained.

When the film storage container is loaded into, for example, an automatic winding camera, the confirmation member changes state (for example, cuts).

It becomes possible to distinguish whether the film has not yet been photographed or the film has already been photographed by looking at the confirmation member.

(Example) Hereinafter, the present invention will be explained with reference to the drawings.

Fig. 1 is an external perspective view showing a film storage container according to an embodiment of the present invention, Figs. 2 and 3 are enlarged views of main parts in Fig. 1, and Fig. 2 shows the state before use of the film. Figures 3 and 3 are diagrams showing the state of used film.

The film storage container 1 shown in the figure is a cartridge that directly winds and stores the photographic film 2.
is housed with the ear portion 2a exposed to the outside. and,
The external protruding end 3 of the winding axis (not shown since most of it is internal) of the photographic film 2 comes to be incorporated into the film winding mechanism (not shown) of the camera, and , a thin film seal (
Confirmation member) 4 is glued together. In addition, thin film seal (
The confirmation member) 4 may be bonded to cover the entire opening 5. In addition, the thin film seal 4 may be provided at an opening (not shown) on the opposite side (lower side in FIG. 1) from the externally protruding end 3.

Further, the thin film seal 4 may be made of thin paper, thin synthetic resin, or the like.

The operation of the film storage container 1 having the above configuration will be explained with reference to FIGS. 2 and 3.

First, the photographer prepares a film storage container 1 (patrone) in which unshot film is stored (as shown in FIG. 2, the thin film seal 4 is in an unbroken state). Then, this film storage container 1 is loaded into, for example, an automatic winding camera. At this time, the external protruding end 3 of the winding shaft is incorporated into the film winding mechanism (not shown) of the camera, and the thin film seal 4 undergoes a state change and breaks as shown in FIG. state. Then, when the photographer starts shooting and shoots a specified number of films, the winding mechanism unit transfers the shot film into the film storage container 1 with the edge 2a of the film 2 exposed to the outside. Rewind. Then, the photographer takes out the film storage container 1 after shooting, stores it, loads a new film storage container 1, and continues shooting.

The above-mentioned operations are repeated until all the images are taken, and a large number of film storage containers 1 are brought to a developing institution and requested to be developed.

According to the film storage container 1 described in detail above, even if some film storage containers 1 containing unshot film are mixed together, a change in the state of the thin film seal 4 (broken state) causes the film to be used up. You can check the condition of the film, and you will not have to develop the unshot film in a developing machine.

It should be noted that the present invention is not limited to the above embodiment,
Various modifications can be made within the scope of the gist.

FIGS. 4 and 5 are external perspective views showing an embodiment of another film storage container. In addition, in FIG. 4 and FIG. 5, the same parts as those explained in the above embodiment are as follows.
The same reference numerals are used to omit detailed explanation.

The film storage container 6 shown in FIG. 4 includes a bottomed cylindrical case body 6a made of synthetic resin that stores the cartridge 1 shown in FIG. 1 inside, and a lid body 6 that fits into the case body 6a.
The thin film seal 4 is bonded across the case body 6a and the lid 6b.

The film storage container 7 shown in FIG. 5 is an outer box made of paper that stores the sealed container 6 shown in FIG.
is bonded across the opening 7a and the side surface 7b.

Even in such film storage containers 6 and 7, the used state and state of the film can be confirmed by the change in the state of the thin film seal 4, as in the embodiment described above.

[Effects of the Invention] According to the present invention described in detail above, it is possible to provide a film storage container and a method for confirming that the film is used, with which the used state of the film can be confirmed.
