Description

[Detailed description of the invention] [Industrial application field] The present invention is a container for storing photographic film, specifically a film packaging container equipped with photographic functions such as a photographic lens and a shutter (hereinafter referred to as "film with lens"). This relates to the suspension structure of the unit.

[Conventional technology]

The applicant has released the ``Urundesu Hi'' and ``Urundesu Flash'' (products), which are lens-equipped film units with built-in 135 film with a cartridge so that you can easily enjoy taking photos even if you do not own a camera. name) is provided. A simple shutter, film winding mechanism, etc. are also built into the unit body of this lens-equipped film unit, and users can enjoy photography simply by purchasing this unit. After shooting, all you have to do is submit the entire unit to a developing shop, and there is no need for any troublesome operations such as taking out the cartridge or cartridge.

By the way, this lens-equipped film unit is
The unit body is tightly packaged in a rectangular parallelepiped case, such as a paper box, and the paper box is further wrapped in a moisture-proof packaging bag for sale. A user who has purchased this lens-equipped film unit opens the packaging bag, takes out the unit body wrapped in a paper box, and takes a photograph in that state.

However, the unit wrapped in a paper box has the disadvantage that it is difficult to carry because its external shape does not have any protruding parts or parts to catch hands. For this reason, for example, as is known from Japanese Utility Model Application Publications No. 63-57651 and No. 63-57652, there are devices that make it easier to carry by attaching or inserting a strap into the main body of the unit, and devices where a strap is attached directly to the opening of the finder. It has been proposed that it be inserted.

[The problem that the idea aims to solve]

However, when the strap is directly inserted through the window opening, a part of the field of view is obstructed by the strap, making it difficult to observe the subject through the window window.

Furthermore, when the strap is fixed to or inserted into the unit body, there are disadvantages in that the structure of the unit body becomes complicated and machining becomes difficult.

[Purpose of invention]

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a strap for a lens-fitted film unit that does not cause the above-mentioned inconveniences and can improve portability with a simple structure.

[Means to solve the problem]

In order to achieve the above object, the present invention forms a notch so as to straddle two adjacent surfaces that are substantially orthogonal to each other in the unit body, and also forms a notch in a part of the wall surface of the unit body that forms this notch when the strap is inserted. A curved surface is provided to serve as a guide surface, and insertion holes are formed in locations corresponding to the front and rear ends of the notch in the unit main body of the exterior body, and these notches and insertion holes are respectively inserted. A strap is used to hang the lens-equipped film unit.

[Effect]

As mentioned above, the present invention provides a notch spanning two adjacent, almost orthogonal sides of the unit body, and also provides a curved surface on the wall forming the notch to correspond to the notch in the unit body of the exterior body. Since the insertion hole is provided at the position, the strap only needs to be inserted into the cavity formed by the notch and the exterior body, and no complicated machining is required and the strap can be inserted very easily.

〔Example〕

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

FIG. 1 shows a lens-fitted film unit according to the present embodiment with one side of the exterior body (paper box 10) opened, and FIG. 2 shows the outer shape of the unit body 12.

In the figure, 14 is a photographing lens provided on the front of the unit body 12, 16 is a viewfinder opening,
18 is a shutter button, 20 is a film winding knob, and 22 is a film counter. Further, the paper box 10 is open at positions corresponding to the photographing lens 14 and the shutter button 18 in order to enclose the unit main body 12 in a state where it can be photographed.

25 is a U-shaped notch formed in the unit body 12, and the wall surface on the back side is a curved surface 25a.

Reference numerals 26a and 26b are insertion holes formed at positions corresponding to the notches 25 of the paper box 10, and these insertion holes 26a and 26b are used for the strap 28 which will be described later.
is designed to be inserted as shown in FIG. In addition, when the paper box 10 is closed, the through hole 26
If the flap 27 of the paper box 10 overlaps the position corresponding to a and 26b, it is necessary to cut out this part as well.

In addition, as shown in FIG. 4, one of the insertion holes 2
For 6b, make a "U" shaped cut 30
It is also possible to do this. In this way, there is no need to make an easily noticeable rectangular hole on the front side, so the appearance until the strap 28 is passed through is not deteriorated. In this case, the strap 28 is inserted through the insertion hole 26a and pulled out through the notch 30. Of course, make the notch 30 a perforation and attach the strap 2.
The notch 30 may be formed when the tube 8 is inserted.

The above-mentioned strap 28 is for hanging the lens-fitted film unit, and in this embodiment, a ring-shaped string is used, but a single band with a hook is used, and one end of the strap is used. The two ends may be connected after being inserted into the insertion holes 26a and 26b. Further, the shape of the strap is not limited to a band-like shape, but may also be a rope-like shape.

Next, the operation and effect of the above embodiment will be explained.

The lens-fitted film unit according to the present invention is sold with the unit body 12 wrapped in a paper box 10 and the unit and strap 28 placed in a packaging bag.

Then, the user who has purchased the lens-fitted film unit opens the packaging bag, pinches any part of the annular strap 28 stored therein, and inserts this part through the insertion hole 26a of the paper box 10. Pull it out from the other insertion hole 26b.
At this time, the strap 28 is inserted through the notch 25 of the unit body 12 and the space formed by the paper box without resistance. At this time, the wall surface on the back side of the notch 25 is the curved surface 25.
a, so when the strap 28 is inserted through the insertion hole 26b, its tip will be on the curved surface 2.
5a, and can be easily pulled out from the other insertion hole 26a.

Then, pass the end of the pulled-out strap 28 through the other end of the annular shape so that it is in the state shown in FIG. Turn the knob 20 to wind the film, point the unit body 12 at the subject, and then press the shutter button 18 to activate the shutter (not shown) and expose the film to the light passing through the photographic lens 14. Ru.

By operating the film winding knob 20 and the shutter button 18 while checking the number of remaining frames on the film counter 22 in this way, a predetermined number of frames are sequentially photographed, and after the photographing is completed, the camera remains in the same state. Submit the film unit with lens to the processing shop.

[Effect of idea]

The strap of the lens-fitted film unit according to the present invention spans two adjacent, almost orthogonal sides of the unit body, and has a notch formed in a part of the wall surface with a curved surface, at a location corresponding to the notch in the exterior body. Since an insertion hole is formed in the lens and the unit is suspended by passing through the hole, there is an effect that the portability of the lens-fitted film unit can be improved with a simple structure.

Further, if an existing lens-fitted film unit having notches on both sides is used, it is only necessary to provide an insertion hole in the exterior body, which is advantageous in terms of cost.
