(57) [Summary] [Purpose] The objective is to protect the camera body with a tough, easy-to-crush outer shell that also serves as an exterior so that it can be used repeatedly. [Structure] Film winding unit 22, lens shutter 24,
The strobe unit 25 and other main mechanical members are directly attached to the camera body 20 made of synthetic resin so that stable related functions can be obtained, and the outer surface of the camera body 20 has excellent weather resistance and impact resistance. It is characterized in that the outer body is arranged by covering with the outer shell member 10 and the camera body 20 is prevented from being damaged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is also referred to as a so-called “shooting-only camera”, and relates to a simplified camera that is preloaded with a film and enables immediate shooting.

[0002]

[Prior Art]

 The “photographable camera” is commercially available by attaching a paper cover that doubles as a decoration on which the product name and handling instructions are printed to the outer surface of a simple camera body made of plastic that is loaded with film.

When the user finishes shooting a film contained in the camera and sends it together with the camera to the processing station to request processing of the exposed film, the paper cover and the camera body are disassembled at the processing station to remove the film after shooting. It is taken out and processed for development, while the camera body is discarded without being used again.

[0004]

[Problems to be solved by the device]

 However, in recent years, recycling of the camera body has been considered from the viewpoint of reusing resources, and in that case, if the method of attaching the paper cover by adhesion is used as usual, the adhesive solidified from the camera body at the time of reuse is used. Removal work is required, which is a major obstacle to recycling.

As a result of solving this problem and improving the present invention, it is possible to easily remove and replace the exterior part of the camera body with its exterior, and the removed parts are also pollution-free. The purpose is to provide a simplified camera that does not touch the screen.

[0006]

[Means for Solving the Problems]

 The above-mentioned object is a simple type camera in which an unexposed film is built into the camera body in advance so that the camera body can be photographed. This is achieved by a simplified camera characterized by the above.

[0007]

【Example】

 An embodiment of the present invention is shown in FIGS.

FIG. 1 is an external view of a simple camera also called a disposable camera containing a 35 mm film (J135), in which 1 is a taking lens, 2 is a viewfinder objective frame, 3 is a shutter button, and 4 is a film winding. The upper knob, 5 is an exponential window of the film counter, 6 is a stroboscopic light emitter, and the number of unexposed screens of the film to be loaded has a so-called remaining number display format and is provided on the outer shell member 10 of the present invention. It is displayed in the index window 5.

FIG. 2 shows the structure of the mechanical portion and outer shell portion of the camera.

Reference numeral 20 denotes a camera body molded from a black synthetic resin material, which forms a film storage chamber for storing the unexposed film under and the exposed film underneath, and by engaging the back cover 21. A light tight state is provided under the film.

The back cover 21 is also formed of the same black synthetic resin material as the camera body 20, and the butterfly device 21 A at one end thereof is press-fitted into and supported by the camera body 20. Therefore, by releasing the engagement of the other end, the film storage chamber can be opened, the film can be easily replaced, and the light tight state can be restored again.

A film winding unit 22 is attached to the upper surface of the camera body 20, the winding knob 4 is connected to the patrone P, and the index board 22A of the film counter is rotated by being wound under the film. It It is placed in a state of interlocking with a sprocket gear (not shown).

On the other hand, on the front surface of the camera body 20, a lens shutter unit 24 incorporating a taking lens 1 and a shutter device 1A with a light-shielding frame 23 interposed is attached, whereby the camera body 20 is brought into a completely light-tight state.

Further, when the lens shutter unit 24 is attached, the linking function of film winding and shutter operation is completed.

Further, a strobe unit 25 having a strobe light emitting device 6 attached to the lens shutter unit 24 is attached to the front surface of the camera body 20 and electrically connected to the shutter device 1A. Since there is a danger of heating the area around the strobe's light-emitting area or where current flows near it, it is even better to subject the hard paper to flameproofing or impregnate it with a flame retardant.

Thus, the camera body 20 having a function as a simple type camera has the appearance as a simple type camera by being covered with the outer shell member 10 according to the present invention, and can be grasped and photographed.

The outer shell member 10 is a lightweight, strong, and extremely low-priced molding member by a so-called paper mold in which a hard paper material is pressure-molded with or without a binder added.

The outer shell member 10 is covered with a peelable sealant on the inner surface in order to shield light and prevent paper dust, and on the outer surface, a paper label printed with a product name and precautions for use. S is pasted. Of course, it is also possible to directly print the outer shell member 10.

Further, the outer shell member 10 is used by coating the surface thereof with a resin bath after molding in order to suppress hygroscopicity. The resin coating coated on this surface can be peeled off after use or before disposal or again.

As a form of mounting the outer shell member 10 on the camera body 20, there are three types shown in FIG.

FIG. 3A shows an outer shell member 10 of a type that covers five surfaces including the front surface of the camera body 20, and covers the camera body 20 from the front surface and then uses a sealing material to provide a back cover 21. Sealed against. Here, the back cover is made of synthetic resin, but it may be made of hard paper, like the outer shell member 10 of the so-called front portion. In this case, in order to stably press the film against the image frame of the camera body 20 at a predetermined interval, only the film pressure plate may be used as a resin plate partially engaged with the body portion.

FIG. 3B shows an outer shell member 10B of a type in which the back surface of the camera body 20 is covered with another member 11B made of the same material as the outer shell member. The separate member 11B is sealed to keep the camera body 20 in a sealed state.

Further, FIG. 3C shows an outer shell member 10C of a type to be covered from the upper surface of the camera body 20, and in this case as well, the camera body 20 is surrounded by adding another member 11C to the bottom surface. It can be sealed.

Since any type of outer shell member described above can be easily crushed, it can be taken out and reused without damaging the camera body 20.

[0025]

[Effect of the device]

 According to the present invention, the outer shell can be used as a protective member that also serves as an outer shell during use, and can be easily crushed during development processing to take out the exposed film and reuse the camera body in a flawless state. The outer shell member, which is protected by the members and which is crushed and removed, will be provided with a simplified camera suitable for reuse that does not generate harmful gas even when incinerated.
