BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior body for a film unit with a lens, which has a built-in film and covers a unit body incorporating a photographing lens and a shutter mechanism.

[0002]

2. Description of the Related Art Film units with lenses such as "Sharing Run Hi" and "Sharing Run Flash" (both are trade names) allow you to take pictures immediately on the spot you purchase them, and develop them as they are after shooting. It is widely used because it is easy to put it in a store. From such a usage pattern, the lens-fitted film unit is made low in cost, and a paper box on which a cosmetic print is applied is used as the exterior. In addition, in order to improve portability, various compactifications have been studied.

As is well known, the lens-fitted photo film unit has a built-in film cartridge for 135 films, and the exposed film is wound around the film film every time a photograph is taken. Therefore, when attempting to make a lens-fitted film unit compact, the outer diameter of the cartridge has a limitation, and it has been impossible to make the entire thickness of the lens-fitted film unit equal to or smaller than the outer diameter of the cartridge.

However, in recent years, various thin type film units having a lens-equipped film unit whose overall thickness is equal to or less than the outer diameter of the cartridge have been tried. As an example of a thin film unit with a lens, part of the unit body with a built-in patrone is projected in a semi-cylindrical shape following the outer diameter of the patrone, and the part with the taking lens is set as the focal length of the taking lens. In addition to the protrusion to the corresponding position, the applicant has studied a cartridge having a thickness equal to or smaller than the outer diameter. According to this, not only can the appearance be considerably thinned as compared with the conventional one, but it can be easily put in the pocket when not in use. Further, the raised portion can also be used as a grip, which is very convenient.

When the unit main body is provided with the projecting portion as described above, it becomes difficult to cover the whole with a paper box used for the exterior. The part incorporating the shooting lens is
Since it is a small part of the entire film unit with lenses, it is sufficient to provide an opening in the paper box and project from this opening like the conventional film unit with lenses, but it is a semi-cylindrical model that follows the outer diameter of the cartridge. Since the portion that is projected like a circle is quite large, forming an opening in the paper box causes the unit main body made of black resin to be largely exposed, which is not preferable in appearance. Moreover, if a large opening is formed in the paper box, the strength of the paper box itself may be reduced.

In consideration of these circumstances, a pair of cuts are made in the paper box to make it easy to bend a part of the paper box sandwiched by these cuts, and this part is bulged into a semi-cylindrical shape by press molding to raise the ridge. It is also considered to cover the parts with paper boxes. In particular, since this raised portion is also used as a grip, it is preferable to cover it with a paper box in order to prevent stains.

[0007]

However, when a pair of cuts are made in the paper box and a part of the paper box is curved as described above, the cut portion expands and becomes an opening, and the unit main body is partially externalized. Will be exposed to. And while various patterns and coloring are given on the surface of the paper box in consideration of the product design, in general, the unit body is molded with black resin in consideration of light shielding property, so as described above. When the main unit of the unit partially appears outside from the opening, there is a problem that the design of the surface of the paper box loses the sense of unity.

The present invention has been made in view of the above circumstances, and even when the cut made in the exterior body to cover the raised portion of the unit body expands as an opening, the color of the unit body that appears through the opening is conspicuous. It is an object of the present invention to provide an exterior body for a film unit with a lens that does not contain the lens.

[0009]

In order to achieve the above-mentioned object, the present invention provides the same color as the unit body around the opening formed in the exterior body to cover the raised portion of the unit body, and through the opening. The color of the observed unit body is made inconspicuous. In addition, when the raised portion is also used as a grip, it is preferable that the curved portion of the exterior body has the same color as that of the unit main body so that the grip portion has an exterior design with a sense of unity.
