Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a film packaging unit (hereinafter referred to as a "lens-equipped film unit") in which a film is preloaded and a photographing function is incorporated. Is.

[Conventional technology]

The lens-fitted film unit is a pre-loaded film unit that contains the shooting lens, shutter, and simple film-winding mechanism inside the container body, so you can take a photo immediately on the spot even when you are not carrying the camera. You can

This lens-fitted film unit needs to be provided at a low price, so the shooting lens, shutter, and unexposed film are installed in a plastic molded container body to form the unit body, which is then packaged in an outer box made of cardboard or the like. It is housed and manufactured. Then, an opening for exposing a taking lens, a shutter button, a finder window, etc. provided in the unit body is formed in the outer box, and a user can perform a shooting operation with the outer box as it is.

[Problems to be solved by the device]

However, when the above-mentioned lens-fitted photo film unit covers the unit body with an outer box, the central part of the outer box swells to form a gap between the outer box and the unit body, which not only makes the appearance unsightly, but also this gap. There is a drawback that foreign substances such as dust and dirt easily get inside and the shooting lens is easily soiled. Especially, the larger the opening of the outer box, the more remarkable such a defect appears.

In addition, in order to eliminate such drawbacks, the folding lines of the outer box are bent so that the surface surrounded by these folding lines is pressed against the unit body side (Japanese Utility Model Application No. 63-542).
No. 73) has already been filed by the applicant, but the sufficient effect was not obtained.

[Purpose of device]

The present invention has been made in view of the above point, and an object of the present invention is to provide a lens-fitted film unit that can prevent a gap from being formed between the unit body and the outer box.

[Means for Solving the Problems]

In order to achieve the above object, the present invention forms an overhanging portion at the outer edge of the exposed portion of the unit body.

[Action]

Since the present invention is configured as described above, even when the outer box is lifted up, the inner portion of the opening contacts the overhanging portion of the unit body, so that a gap is created between the outer box and the unit body. There is no.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a state of a unit main body 10 and an outer box 12 covering the unit main body 10 according to one embodiment. In the figure, the unit main body 10 includes a negative film (not shown), a photographing mechanism, and a strobe unit. At the center of the front surface of the unit body, a semicircular ridge 16 having a taking lens 14 is formed. A lens switching unit (not shown) that switches the shooting mode between standard shooting and macro shooting is provided inside the raised portion 16, and the shooting mode can be switched by sliding the switching lever 18 left and right. It has become. In addition, this switching lever 18
When the macro photographing mode is set by the operation of, the macro display member 20 projects into the finder 22 to inform the photographer that the macro photographing mode is set.

On the upper portion of the raised portion 16 and the outer edge of the finder 22,
To prevent a gap between the outer box 12 and the unit main body 10, a protruding portion 23, 2 protruding in a direction perpendicular to the unit main body 10 is formed.
4,25,26 are formed.

A strobe 28 is provided in the upper right part of the unit main body 10,
A flash charge switch button 30 for preparing the strobe 28 for light emission is provided below the flash charge switch button 30. A shutter button 32 and a counter window 34 for displaying the number of films are formed on the upper surface of the unit body 10.

On the other hand, the outer box 12 has a unit body configured as described above.
An opening is formed to expose each part of 10.
That is, the opening 16a for the raised portion 16, the opening 22a for the finder 22, the opening 28a for the strobe 28, the notch 30a for the flash charging switch button 30, and the opening 32 for the shutter button 32.
The openings 34a for the a and the counter window 34 are formed at the corresponding positions.

FIG. 2 is an external view of the lens-fitted film unit 40 in which the unit body 10 is housed in the outer box 12, and FIG.
The state of the cross section cut in the A direction is shown.
In particular, as shown in the figure, when the finder opening 22a and the lens portion opening 16a have an opening shape that allows them to communicate with each other, there is a tendency to move toward the front edge of the central portion that defines the opening. When the overhang portions 24 and 25 are formed, the edge surface of the opening 22a is formed into the overhang portions 24 and 25.
The outer surface of the unit is brought into contact with the outer surface of the unit and the gap between the outer box 12 and the unit body 10 is completely hidden. Since the other projecting portions 23 and 26 also operate in the same manner, the appearance of the lens-fitted photo film unit is not impaired, and dust does not enter between the unit body 10 and the outer box 12.

Further, overhanging parts such as 23 to 26 may be provided not only in the finder part and the lens part but also around the strobe light emitting window 28. Also, the shape of the overhanging portion should be bulged toward the center of the unit.

Further, although the lens-fitted film unit capable of macro photography has been described in the above embodiment, the present invention is not limited to the application having such a configuration, and the unit body is covered with the outer box. It goes without saying that the above-described structure can be applied to a conventionally known lens-fitted film unit in which the lens is not replaced.

[Effect of device]

In the present invention, since the gap is not formed between the unit body and the outer box due to the overhanging portion on the outer edge of the exposed portion of the unit body, the aesthetic appearance of the lens-fitted photo film unit as a whole is not impaired, and further, the unit body and the outer box. There is an effect that it is possible to avoid a functional adverse effect caused by the entry of foreign matter between and.
