Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in storage of a single-use camera, and more particularly, to a change in photographic film characteristics due to the influence of gas generated from various parts in an unused sealed state. A single-use camera and a single-use camera housing.

[0002]

2. Description of the Related Art A one-time-use camera is constructed so as to function as a camera by attaching a lens or the like to a resin case containing a photographic film. That is, the unused photographic film is mounted in the camera in a photographable state.

FIG. 3 is a block diagram showing the outline of the main unit 16 with the back cover 17 of the conventional single-use camera removed. In this figure, all the frames of the unexposed photographic film 11 are wound on the spool 10 in advance.
And by operating the winding knob 25 at the time of shooting,
It is configured such that the photographing is performed while rewinding each frame in the cartridge 12 one by one. As a result, photographic film 11
When shooting is finished after all the
Most of the 1s are wound into the cartridge 12.

The battery 14 is housed in a battery box 24, and an inverter circuit 23 for stroboscopic light emission.
Are housed under the battery box 24 and the film chamber 21 in this figure. Further, the capacitor 15 of the inverter circuit 23 is arranged substantially in the center lower part of the main body unit 16.

In order to protect the photographic film from moisture, light and the like from the outside, this kind of single-use camera is generally placed in a store in a sealed state by a barrier package of resin coated with aluminum. FIG. 4 is a cross-sectional view showing a state of a cross section of the container with the barrier packaging (bag) 31. In such a single-use camera 1, the unexposed photographic film is distributed in a state of being incorporated therein and is displayed in a store. Therefore, it is necessary to take measures to prevent deterioration of photographic film characteristics.

[0006]

In this type of single-use camera, an alkaline manganese battery is generally used as a strobe battery because of its low internal resistance and good storage characteristics during strobe charging. .

On the other hand, in such a single-use camera with a built-in strobe, a small amount of gas may be generated from the battery even when it is not used. Further, there is a possibility that gas may be similarly generated from the large-capacity electrolytic capacitor 15 and the like used in the inverter circuit 23. It is also expected that such a gas will have some influence on the photographic film. For example, alkaline manganese batteries generally have the property of generating hydrogen gas. When such hydrogen gas is generated, it is expected to affect the color development of the photographic film. It is also possible that other types of harmful gases are generated depending on the type of parts used.

However, since the barrier package forming the container is hermetically sealed to suppress the influence from the outside, there is a problem that no consideration is given to the gas generated inside. When gas is generated from the battery inside the barrier package, the gas stays inside, and the influence on the photographic film cannot be ignored.

The present invention has been made to solve the above problems, and provides a single-use camera and a single-use camera housing in which harmful gas that may be generated from a battery or an inverter circuit component is taken into consideration. Aim to achieve.

[0010]

DISCLOSURE OF THE INVENTION The present invention for solving the above-mentioned problems is a single-use camera in which an unexposed photographic film is housed in advance, a stroboscopic light emitting means and a battery are built in, and the package is sealed by a sealing member until the start of use. In the above, the photographic film is characterized in that an adsorption means having a property of adsorbing a harmful gas is arranged.

Further, in a single-use camera housing for accommodating a single-use camera incorporating an unexposed photographic film, a stroboscopic light emitting means and a battery, a harmful gas is adsorbed on the inner surface of the sealing member. It is characterized in that a suction means having characteristics is provided.

[0012]

In the sealed state before the start of use, the gas harmful to the photographic film generated inside the package is used up and is adsorbed by the adsorbing means provided in the camera, so that the characteristics of the photographic film are not adversely affected. Also, in the sealed condition before the start of use, the harmful gas generated in the package inside the photographic film will be exhausted and the adsorption means provided on the inner surface of the camera housing will not adsorb the photographic film and will not reach the photographic film characteristics. There is no adverse effect.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a configuration diagram showing a state in which the back cover of the configuration of the first embodiment of the present invention is removed. In this figure, all the frames of the unexposed photographic film 11 are wound on the spool 10 in advance. Then, at the time of shooting, by operating the winding knob 25, the shooting is performed while rewinding each frame in the cartridge 12 one frame at a time. In addition, the battery 14 is housed in a battery box 24, and an inverter circuit 23 (not shown) for strobe light emission.
Are housed under the battery box 24 and the film chamber 21 in this figure. Further, a gas adsorbent 26 having a property of adsorbing harmful gas is arranged between the battery box 24 and the film chamber 21.

Prior to the start of use, as described with reference to FIG. 4, the package is sealed with a barrier package, and various harmful gases will drift near the photographic film 11. For example, the harmful gas generated from the battery 14 in the battery box 24 is not adsorbed near the photographic film 11 because it is adsorbed by the gas adsorbent 26 in front of the film chamber 21. Therefore, the characteristics such as the color balance of the photographic film 11 are not affected at all. In addition, the inverter circuit 2
The harmful gas generated from the condenser 15 of No. 3 is also adsorbed by the gas adsorbent 26 on the side of the film chamber 21 in the same manner.

Although various gases are expected as harmful gases, if the photographic film 11 is to be protected from oxygen, a gas adsorbent containing an oxygen scavenger is used. In addition, if it is desired to protect formaldehyde from the packaging material or molding material, a gas adsorbent containing a deforming agent is used. Furthermore, if the photographic film 11 is protected from hydrogen generated from the battery 14 and the strobe capacitor 15, a hydrogen adsorbing alloy can be used.

When the gas adsorbent 26 is arranged between the battery 14 which is particularly apt to generate gas and the unexposed photographic film 11, the deterioration of the photographic film 11 can be effectively prevented.

In the above embodiments, the gas adsorbent 26 is arranged between the battery box 24 and the film chamber 21, but the invention is not limited to this. For example, the film chamber 21
The gas adsorbent 26 may be adhered or applied over the entire surface or may be impregnated with the resin forming the main body unit 16, which improves the space efficiency. It is also conceivable to dispose the gas adsorbent 26 on the back cover that holds down the photographic film 11. Further, the gas adsorbent 26 may be housed in an empty space near the objective lens.

It is also conceivable to dispose the gas adsorbent 26 near a part that may generate harmful gas. In this case, battery 14 and strobe condenser 15
It may be possible to arrange the battery box 24 or the capacitor 15 in the vicinity of the electrodes of the capacitor 15, and it is expected that the adsorption efficiency of harmful gas is improved by doing so.

FIG. 2 is a block diagram showing a schematic structure of the second invention. Here, a configuration is shown in which the gas adsorbent 261 is attached to the lens side of the inner surface of the barrier bag (packaging) 31 without modifying the body unit of the camera itself. For example, when the gas adsorbent 261 is formed by mixing a gas adsorbent with an elastic material such as sponge, it can also serve as lens protection. Also, the main unit 1
It is also possible to apply the gas adsorbent 261 to the outer paper cover of 6 or the like. Further, it is possible to fill the barrier package with a gas that reacts with a specific gas or to mix the gas in a certain amount.

As described above, since the photographic film inside the barrier package sealed by the gas adsorbent having the property of adsorbing harmful gas is configured to be protected from the harmful gas, the harmful gas is not used in the unused state. The characteristics will not change under the influence of.

[0021]

As described above in detail, in the present invention, since the photographic film is protected from harmful gas by using the gas adsorbent, even in the unused sealed state. The photographic film is shielded from harmful gases and its effects no longer change the photographic film properties.
