Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens-fitted film unit in which a band-shaped exterior body is wound around an outer peripheral surface of a unit body incorporating a photographing mechanism.

[0002]

2. Description of the Related Art A lens-fitted film unit is commercially available from the applicant of the present invention so that photography can be easily enjoyed at a low price. The film unit with lens is
An unexposed photo film is built into the unit body that incorporates a simple shooting mechanism, and the surface is covered with an exterior body so that you can take a picture immediately on the spot you purchased it, and you can also develop it after shooting It is widely used because it is convenient to put it in a store.

The lens-fitted film unit is advantageous in that it can be provided at a low price, and it is necessary to manufacture the lens-fitted film unit at the lowest possible cost. Therefore, the exterior body that covers the unit body is a paper box having a cosmetic print on the surface. It is used. Recently, a lens-fitted film unit that uses a strip-shaped label as an exterior body instead of a paper box is known, for example, from Japanese Patent Application No. 3-56924. This lens-fitted film unit has a strip-shaped label wrapped around the outer periphery of the unit body and glued, leaving both sides of the unit body exposed, compared to a unit that covers the entire surface of the unit body with a paper box. There is an advantage that the compact image can be enhanced and the assembly is simplified. A lens-fitted film unit that adheres the front surface of the unit body to the back surface of the outer body in order to further improve the adhesion between the unit body and the outer body is known, for example, from Japanese Patent Application No. 2-57427. There is.

On the other hand, in order to conserve resources and reduce industrial waste, the lens-fitted film unit is being actively recycled. When the user takes the film unit with a lens that contains the photo film that has been taken to the development shop, the film unit with the lens is further collected at the developing place, where the photo film is taken out, and the film development and print processing are performed. Is done. The lens-fitted photo film unit after the photo film is taken out is collected by the manufacturer, and after the exterior body is removed from the unit body, the unit body is disassembled into parts. The parts that can be reused are supplied to the manufacturing process as they are, and the parts that cannot be used are used as raw materials. In addition, the exterior body removed from the unit body is remelted and recycled as recycled paper.

[0005]

However, in the case of the lens-fitted film unit in which the unit body and the exterior body are directly bonded to each other, when the exterior body is removed from the unit body, a specially shaped blade is used to remove the exterior body from the exterior body. It is necessary to peel off a part of the adhesive part, pick up this peeled part, and peel it off from the unit body. Moreover, since this peeling work must be performed individually by hand, it is very time-consuming and not efficient. In addition, since the adhesive is often left on the surface of the unit body after the exterior body is peeled off, a cleaning process is provided to attach the adhesive in order to recycle the unit body. It is necessary to completely remove the adhesive.

The present invention has been made in order to solve such a problem, and it is possible to improve the efficiency of the removal work of the exterior body while improving the adhesion between the unit main body and the exterior body. An object is to provide a film unit with a lens.

[0007]

In order to achieve the above object, the lens-fitted photo film unit of the present invention has a structure in which the outer peripheral surface of the unit body covered with the exterior body is covered with a transparent shrink film in a ring shape to form the exterior body. The surface of the shrink film is overlapped with the surface of the shrink film, and the front surface of the shrink film is adhered to the back surface of the exterior body.

It consists of 0 and. The unit main body 11 is mainly made of plastic and has a taking lens 12, a viewfinder objective window 13, a strobe light emitting section 14, and a strobe charging switch 15 on the front surface thereof, and a shutter button 16 and a counter window 17 on the upper surface thereof. There is. As shown in FIG. 2, a winding knob 18 and a viewfinder eyepiece window 19 are provided on the back surface of the unit body 11.

The central portion of the unit main body 11 is covered with a transparent shrink film 20 in a ring shape. The shrink film 20 includes a photographing lens 12, a viewfinder objective window 13 provided on the unit main body 11,
Holes 21 to 24 for exposing the counter window 17 and the viewfinder eyepiece window 19 are formed. As the shrink film 20, a heat-shrinkable film that shrinks when heated may be used, and for example, a polyethylene film or a polyvinyl chloride film may be used.

The label 30 is for making the appearance of the lens-fitted film unit 10 clean, and is made of one strip of paper. This label 30 covers the central portion of the box-shaped unit body 11 in order to cover the rear cover portion 31, the upper surface cover portion 32, and the front cover portion 3.
3, and the bottom cover portion 34, and is wound around the unit main body 11 so as to overlap the surface of the shrink film 20. The necessary portions of the label 30 are provided with openings 35 to 38 for exposing the taking lens 12, the viewfinder objective window 13, the counter window 17, and the viewfinder eyepiece window 19 provided on the unit body 11 to the outside. Thirty
The shooting operation can be performed with the unit being wound around the unit main body 11. An adhesive is applied to the back surface of the label 30 and is attached to the front surface of the shrink film 20.

In the process of assembling the lens-fitted photo film unit 10, the unit main body 11 incorporating the photographing mechanism and the unexposed photo film is the shrink film 20.
Sent to the coating process. First, the shrink film 20 is wound around the center of the unit main body 11, and both ends of the shrink film 20 are overlapped and welded.
After that, when the shrink film 20 portion of the unit body 11 is heated, the shrink film 20 contracts and comes into close contact with the surface of the unit body 11.

The unit body 11 covered with the shrink film 20 is transferred to the step of attaching the label 30. In the process of applying the label 30, first, the label 30
The front cover portion 33 of the above is superposed on the front surface of the unit main body 11 from above the shrink film 20 and pressure-bonded thereto. Next, the bottom surface cover portion 34 adjacent to the front surface cover portion 33 is attached to the shrink film 20 covering the bottom surface of the unit main body 11. After that, when the top cover portion 32 and the back cover portion 31 are sequentially attached to the surface of the shrink film 20, the lens-fitted film unit 10 is completed.

As described above, the shrink film 20
Is heated after being wound around the outer peripheral surface of the unit main body 11 in a ring shape, so that the heat shrinks and is in close contact with the unit main body 11. Since the front surface of the shrink film 20 and the back surface of the label 30 are directly adhered to each other, the unit body 11 and the label 30 are in close contact with each other without a gap.

The photographer uses the film unit 1 with a lens.
Photographing is performed using 0, and when the photographing of all frames is completed, the lens-equipped film unit 10 is brought to a development handling shop and a DPE is requested. The photographed lens-fitted film unit 10 is further collected from a development handling store to a developing place, where the exposed photographic film is taken out from the unit main body 11. The photo film taken out from the unit main body 11 is subjected to film development and print processing, and the resulting print photo is delivered to the photographer's hand through a photo shop. On the other hand, after the photographic film is taken out, the lens-fitted film unit 10 is collected from the developing station by the manufacturer and sent to the disassembling process for reuse.

In the disassembling step of the lens-fitted film unit 10, the label 30 is first removed from the unit body 11. To remove the label 30, for example, refer to FIG.
