DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a film packaging container (hereinafter referred to as a "film unit with lens") having a photographing function such as a photographing lens and a shutter.

[Conventional technology]

From the applicant, the product name is "Sharing Run", "Sharing Run H"
There is provided a film unit with a lens known as "i" or the like. These lens-fitted film units are so popular that they can immediately take pictures on the spot when they are purchased.

The lens-fitted film unit known from Japanese Utility Model Laid-Open No. 1-57742 covers the entire body (unit body) of the lens-fitted film unit described above entirely with a plastic cover and is not suitable for use in water. say,
It is designed so that it can be used on the coast and other watersides without worrying about getting wet with water droplets and the adhesion of sand.

[Problems to be solved by the invention]

However, in the lens-fitted film unit described in the above publication, the front surface of the taking lens incorporated in the unit body is also covered with a part of the cover, so that not only loss of light amount occurs at the time of shooting, but also flare and ghost occur. It has the drawback of being easily generated.

[Purpose of device]

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a film unit with a lens which has a waterproof function for daily life and which does not cause flare or ghost during photographing.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention forms an opening in a part of a cover that covers a unit body for waterproofing life.
The diameter of the opening is made smaller than the diameter of the raised portion around the photographing lens so that the photographing lens is directly exposed to the outside through this opening and the edge of the opening is brought into close contact with the unit body. .

[Action]

Since the photographing lens is exposed to the outside through the opening formed in the waterproof cover, it is possible to perform photographing regardless of the waterproof cover. Further, the edge of the opening is closely attached to the unit body without any gap, and foreign matter such as water droplets or sand does not enter between the unit body and the waterproof cover.

An embodiment of the present invention will be described below with reference to the drawings.

〔Example〕

Appearances on the front side and the back side of a film unit with a lens to which the present invention is applied are shown in FIGS. 1 and 2, respectively.
The unit body 2 made of plastic has a dark box structure, in which 135 film with a cartridge (“I
SO: 1007-11979 "standard),
The back cover 2a is fixed so that the user cannot take out the film.

A shutter mechanism, a simple film winding mechanism and a film counter mechanism are built in the unit main body 2, and a photographing lens 3, a viewfinder objective window 4, a viewfinder eyepiece window 5, a shutter button 6 and a counter window are externally provided. 7, a winding knob 8 is provided. On the front surface of the unit main body, a tapered ridge 10 is integrally formed so as to surround the taking lens 3. Further, the upper edge of the finder objective window 4 enters the back side as shown by the broken line 4a. Further, the concave portion 1 is provided on the back surface of the unit body 2.
1 is formed in which a winding knob 8 is provided.

The unit body 2 is tightly packaged in a cardboard dressing box 12 on which patterns, designs and the like are printed. FIG. 3 shows a state in which the cosmetic case 12 is expanded, and an opening 14 corresponding to each of the photographing lens 3, the viewfinder objective window 4, the viewfinder eyepiece window 5, and the counter window 7 is provided in a required portion thereof.
17 are formed. A transparent vinyl cover 20 is laminated on the entire surface of the case 12. Then, after being laminated on the cosmetic case 12, an opening 21 is punched out at a portion corresponding to the taking lens 3 in the vinyl cover 20, and further at a portion corresponding to the winding knob 8,
An opening 22 is punched out in the cosmetic case 12 together with the vinyl cover 20. In addition, cuts 2 are provided at a position corresponding to the shutter button 6 and at two positions on the lower edge of the opening 22.
3, 24 are formed.

The inside diameter of the opening 21 formed corresponding to the taking lens 3 is smaller than the root-side large-diameter portion of the tapered ridge 10 and larger than the front-side small-diameter portion of the ridge 10. A printing area 25 of black ink is formed on a part of the back surface of the case 12 so as to extend along one side of the opening 12. Since the vinyl cover 20 is completely adhered to the cosmetic case 12, even if water drops are applied to the surface side of the cosmetic case 12, the cosmetic case 12 made of paper swells with water and the commercial value is significantly reduced. It never happens. In addition, it is possible to give a display effect to the vinyl cover 20 by appropriately printing it.

When the cosmetic box 12 laminated with the vinyl cover 20 as described above is assembled, and the unit body 2 is put in the packaging case 12 and wrapped, the raised portion 10 of the unit body 2 enters the opening 21. At this time, since the inner diameter of the opening 21 is smaller than the large diameter portion of the raised portion 10, the edge of the opening 21 closely adheres to the tapered surface of the raised portion 10 as shown in FIG.
No foreign matter such as water droplets or sand will get in. In addition, the winding knob 8 is exposed from the opening 22 so that it can be operated externally. Further, the notch 23 is aligned with the shutter button 6, the openings 15 and 16 are aligned with the finder objective window and the eyepiece windows 4 and 5 of the unit body 2, and the opening 17 is aligned with the counter window 7. The print area 25 formed on the back surface of the cosmetic case 12 covers the notch 4a of the finder objective window 4.

The operation of the film unit with a lens having the above structure will be described. At the time of photographing, framing is performed through the viewfinder eyepiece window 5 through the viewfinder objective window 4 through the vinyl cover 20. At the time of this framing, since the upper side of the finder objective window 4 has a low reflection due to the black print area 25, the observation of the subject screen becomes clear.
And the cosmetic case 1 laminated with the vinyl cover 20
When the shutter button 6 is pressed from above 2, photographing is performed through the photographing lens 3 by opening and closing the shutter. At this time, the opening 21 of the vinyl cover 20 is attached to the taking lens 3.
Since the subject light is directly incident therethrough, it is possible to take a good photograph without flare or ghost.

The winding stop is released at the same time as the shooting, and the operation of the winding knob 8 is allowed. The exposed film is wound up by directly operating the winding knob 8 through the opening 22. It should be noted that if a part of the cosmetic case 12 is pushed into the recess 11 using the cutout 24, the amount of protrusion of the winding knob 8 increases, and thus the winding operation becomes easier.

The film that has been wound up is wound into the cartridge that is built in the unit body 2. Shutter charging is performed together with the film winding, and when the film winding for just one frame is completed, the winding is stopped again and the winding knob 8 is locked. This completes the preparation for the next shooting. Of course, the number of film frames can be confirmed on the counter window 7 through the vinyl cover 20.

In this way, since the photographing operation is performed through the vinyl cover 20 that covers the unit body 2, the unit body 2 will not get wet even if some water droplets are applied to the lens-equipped film unit.

FIG. 3 shows another embodiment. In this embodiment, the edge of the opening 21 of the vinyl cover 20 is joined to the taper surface of the raised portion 10 by a waterproof ring-shaped seal 28 and rolled up again. The opening 22 that exposes the knob 8 is also joined by a rectangular frame-shaped seal 29. According to this, it becomes possible to more reliably prevent water droplets or the like from entering through the openings 21 and 22.

In the above embodiments, the entire surface of the vinyl cover 20 is made transparent, but only the parts necessary for shooting, such as the taking lens of the unit body 2, the viewfinder objective window and the eyepiece window, may be made transparent. By further decorating the opaque part, the makeup box 1
2 can be omitted. Further, the shape of the raised portion around the photographing lens is not limited to a circular shape when viewed from the front as in the above embodiment, but may be a rectangular shape or another polygonal shape.

[Effect of device]

As described in detail above, the film unit with a lens of the present invention has an opening formed in the waterproof case that covers the unit main body, and shooting is performed through this opening. This allows for good photography without flares or ghosts. Further, since the edge of the opening for exposing the taking lens is designed to be in close contact with the surface of the unit main body, it is possible to reliably prevent water from entering through the opening.
