Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera body in which a specific protective seal is attached to an exposed metal surface,
The present invention relates to a protective seal for a camera body, a protective seal kit, and a method for manufacturing the same. More specifically, the present invention relates to a camera to which a protective seal is attached because it is necessary to protect the surface of a high-grade camera or a valuable camera, the protective seal, and a comprehensive protective seal kit.

[0002]

2. Description of the Related Art When handling a valuable camera or a high-grade camera, there is a demand for preventing the exposed metal surface of the camera body from being damaged during handling of the camera. To meet such demand, it is necessary to provide a protective cover on the bottom of the camera.
No. 2122 is known. This real application Sho 55-9
Japanese Patent No. 2122 relates to a protective cover formed in substantially the same shape as the bottom surface of a camera, and a rib projecting in the center of the top surface of the cover is pushed into a tripod mounting screw hole so that it can be mounted on the bottom surface of the camera. Has become.

The protective cover prevents the bottom surface of the camera from being scratched when the camera case is taken out and temporarily placed on an object, and is removed from the camera when the camera is put into the camera case again. Be done.

[0004]

However, even if the exposed metal surface of the upper surface of the camera is protected by this protective cover, it cannot be used because there is no hole for locking the protective cover. In addition, the protective cover greatly changes the aesthetics (shape, color, etc.) of the camera, making it unsuitable for applications such as exhibitions. Furthermore, when the camera is housed in a camera case or fixed to a tripod, the protective cover needs to be removed, and the surface protection function cannot be fulfilled.

The present invention solves such a problem, and a camera having a structure in which most of the exposed metal surface of the camera body is protected from external force so that the exposed metal surface is not damaged. An object of the present invention is to provide a protective seal attached to the exposed metal surface to protect the body from external damage, a protective seal kit for distributing the protective seal, a method for producing the same, and the like.

[0006]

The camera according to claim 1 is
It is characterized in that a transparent or opaque protective seal, or a transparent and / or opaque seal is laminated on the exposed metal surface of the camera body. In such a camera, since the exposed metal surface is covered with a protective seal, the exposed metal surface is not damaged by a slight external force or impact, and the protective seal is transparent or translucent. The appearance of the exposed metal surface and the metallic luster, etc., are hardly impaired. Here, the protective seal means a film-like or film-like sheet-like body which is attached to the metal exposed surface and covers the exposed surface, and an adhesive is applied to the back surface thereof.

According to a second aspect of the present invention, the protective seal for a camera body is transparent or semi-transparent, and has a contour having substantially the same shape as the exposed metal surface (A) of the camera body (2). Since this protective seal is prepared for each location of the "metal exposed surface", a plurality of sheets having different shapes are provided. Also,
If the surface is a curved surface or a metal exposed surface that is a refraction surface, protection is provided by a plurality of protective seals.

A camera body protective seal kit according to a third aspect of the present invention is a transparent or translucent protective seal (S) having a contour of substantially the same shape as the metal exposed surfaces (A) of a plurality of portions of the camera body (2). And a release paper (17) to which each protective seal is attached. There are multiple types of protective seals, but this protective seal kit makes it possible to perform work in sequence even if the location where it is attached to the camera body is different. be able to.

Further, as described in claim 4, the protective seal (S) has the same shape as the outer shape of the camera part (P) protruding from the metal exposed surfaces (A) of a plurality of portions of the camera body (2). It is possible to provide a cutout contour portion (18) cut out by (4) and a cutout portion (20) that can open a part of the cutout contour portion toward the outside. When the camera component is projected from the exposed metal surface to which the protective seal is to be attached, how to attach the protective sheet to the exposed metal surface becomes a problem. Therefore, as shown in the invention of claim 4, by sticking out the corresponding portion, the sticking work can be performed without causing a portion which cannot be stuck due to the camera parts.

Further, as described in claim 5, the protective seal (S) has a plurality of adjacent cutout contour portions (18).
The cutout contour portions adjacent to each other can communicate with each other. When two or more projecting camera parts are arranged close to each other, it is preferable that the cutout contours matching the shapes of the camera parts are arranged in communication with each other, as described in claim 5. . This is because when the cutout contour portions are very close to each other, the distance between the contour portions becomes very narrow, and the protective sheet cannot retain its shape.

According to the sixth aspect of the present invention, in the method for producing a protective seal for a camera body, the contour information of the exposed metal surface (A) is extracted from the image obtained by photographing the exposed metal surface (A) of the camera (2). The contour information extracting step for cutting, the cutting step for cutting the protective seal (S) for protecting the exposed metal surface from the sheet material by inputting the contour information into the cutting device, and the cut-out protective seal for release paper ( 17) is included. A computer incorporating image processing software and cutting information input software is used for extracting the above-mentioned contour information and inputting the contour information to the cutting device.

Further, as described in claim 7, the protective seal (S) obtained in the cutting step is applied to the exposed metal surface (A) of the camera (2), and the protective seal (S) and the It is checked whether the contour shape of the exposed metal surface (A) is different, and if it is different, the contour information is corrected so as to match the contour shape of the exposed metal surface (A), and the cutting step is performed again. Can be prepared. Since the image obtained by photographing the camera is obtained by projection, the necessary contour may not be obtained in some cases. Therefore, by providing the “correction step”, a more accurate contour can be obtained. .

The protective seal preferably has a thickness that does not hinder the operation of the levers and buttons of the camera. This thickness is 0.1 mm from the lever gap because the lever is arranged in the camera with a gap of 0.5 to 3 mm.
A thickness of at least mm is preferable. The protective seal may be any sheet as long as it can protect the exposed metal surface of the camera, and examples thereof include a sheet of synthetic resin or aluminum.

Further, the protective seal may be transparent, translucent or opaque, or colored or uncolored. This is because uncolored transparent is selected when the color of the camera is required, and opaque or colored sheet is selected when the atmosphere of the camera is changed. Further, as a method for attaching the protective seal, it is possible to exemplify that an arbitrary adhesive is applied in advance to the surface of the protective seal that faces the metal exposed surface and the adhesive is applied.

BEST MODE FOR CARRYING OUT THE INVENTION Next, the most preferred embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a camera 1 to which the present invention is applied basically includes a housing-shaped camera body 2 and a lens body 4 attached to a front cover portion 3 of the camera body 2. Has been done. The camera body 2 includes the front cover portion 3, side cover portions 5a and 5b formed by bending both side portions of the front cover portion 3 and extending rearward, and parallel to the front cover portion 3 at a predetermined distance. A rectangular tubular body including a rear cover portion (or a lid body, not shown) hinged to one of the portions 5a and 5b so as to be able to open, and the front cover portion 3 and the side surface cover portion at the upper and lower ends thereof. The upper cover portion 6 and the bottom cover portion 7 integrally fixed to 5a and 5b form a closed container.

The front cover part 3 is formed of a metal plate as a whole, and the metal plate has a metal exposed surface A whose surface is directly exposed to the outside and a non-exposed metal plate which is decorated with natural leather or synthetic resin. It is a decorative surface B. The metal exposed surface A has a substantially T shape, and the central portion thereof serves as a mounting portion 3a of the lens body 4. The upper left portion of the exposed metal surface A is the mounting portion 3b of the finder window 8, while the upper right portion is the second focal length different from the first focal length adjusting means 9 mounted on the lens body 4. It serves as a housing chamber 11 for the adjusting means 10. The accommodation chamber 11 is provided with a focus adjustment window 12 which defines a focus adjustment area, and the non-exposed decorative surface B is provided with a self-timer starting member 21.

Both the top cover portion 6 and the bottom cover portion 7 are formed of a metal plate, and the metal plate is also a metal plate exposed surface A exposed to the outside. A film support shaft 13 and a film take-up shaft 14 each having an axial center in the vertical direction are axially supported by both cover parts at a predetermined distance.
A handle protruding rearward from the rear cover (not shown)
When the film take-up shaft 14 is rotated by causing the film, the film (not shown) supported by the film support shaft 13 in the camera body 2 is moved forward frame by frame.

Further, a camera part P such as a release button 15, a shutter speed adjusting button 16 and a gutter-shaped strobe mounting member 17 is erected between the film support shaft 13 and the film winding shaft 14 in the upper surface cover portion 6. It is set up.

Next, a protective seal, which is transparent, semi-transparent or opaque and has a pressure-sensitive adhesive applied to the back surface, is attached to the exposed metal surface A of the camera body 2 of the camera 1 thus constructed. To be That is, as shown in FIG. 2, the mounting portion 3a of the lens body 4 in the front cover portion 3, the mounting portion 3b of the finder window 8, the housing chamber 11 of the second focal length adjusting means 10 and the exposed metal surface A of the upper cover portion 6 are shown in FIG. To
A protective seal S having the same contour as those shapes is attached. Further, a protective seal S is also attached to the exposed metal surface A of the film support shaft 13, film winding shaft 14, release button 15, and shutter speed adjusting button 16. Although not shown in FIG. 2, a protective seal S is also attached to the outer surface of the bottom cover portion 7 in a similar manner (see FIG. 4 described later).

When the protective seal S is attached to the exposed metal surface A, a plurality of transparent or translucent protective seals S having a contour of substantially the same shape as the exposed metal surface A are prepared. Reproduce the layout on the release paper using release paper, and put the protective seal S on the release paper.
The pieces are peeled off one by one and attached to the exposed metal surface A.

For example, when the protective seal S is attached to the upper surface cover portion 6 which is the exposed metal surface A, the release paper 17 having a shape larger than that of the upper surface cover portion 6 as shown in FIG.
Is prepared, and the protective seal S6 having the contour of the shape of the upper surface cover portion 6 is divided into two and attached onto the release paper 17. Then, in the divided seal S61 obtained by dividing the protective seal S6 in half, a protective seal having the same contour as the shape of the upper surface of the film support shaft 13 in the cutout contour portion 18 cut out in the same shape as the outer shape of the film support shaft 13. S1
Place 3 and paste.

Similarly, a cut-out contour portion 18 having the same contour as the shape of the camera part P such as the film winding shaft 14, the release button 15 and the shutter speed adjusting button 16 is formed on the remaining divided seal 62, and among them. A protective seal S14 having the same contour as the upper surface of the camera part P,
Stick S15 and S16. Similarly, as shown in FIG. 4, the mounting portion 3a of the lens body 4 in the front cover portion 3, the mounting portion 3b of the finder window 8, the accommodation chamber 11 of the second focal length adjusting means 10, and the side surface cover portions 5a and 5b are provided. The protective seals S11, S3a, S5a and S5b are peeled off from one release paper 17 and attached to the exposed metal surface A. Further, protective seals S71 and S72 are attached to the exposed metal surface A of the bottom cover portion 7.

In this way, a protective seal kit 19 is prepared in which a plurality of types of protective seals S are arranged and adhered on the release paper 17, and the protective seals S are peeled from the kid 19 one by one. By adhering them to the exposed metal surface A of the camera body 2, the attaching work of the protective seal S to the exposed metal surface A can be made efficient.

Further, when the exposed metal surface A includes an inclined surface, in order to make the attaching work more efficient and to attach the protective seal S to the exposed metal surface A neatly, The flat surface and the inclined surface may be covered with the protective seal S at the same time by bending a part in the middle or near the end. For example, with respect to the inclined flat surface 6a between the steps formed on the upper surface cover portion 6 of FIG.

Further, in the pasting work, a protective seal S
Since it is difficult to insert the camera part P into the cutout contour portion 18 formed in the above, as shown in FIG. 5, a part of the cutout contour portion 18 can be opened outward. By providing 20 and making the area of the cutout contour portion 18 slightly distorted, the camera component P
Is easily inserted into the cutout contour portion 18, and after the insertion, the cutout portion 20 is returned to the original state so that the cutout contour portion 18 is fitted to the camera part P. If a plurality of the cutout contour portions 18 are adjacent to each other and it is difficult to form the cutout portions 18 adjacent to each other, the adjacent cutout contour portions 18 are cut off and the cutout contour portions are adjacent to each other. 18
The communication of the camera parts P facilitates the insertion of the camera part P into the cutout contour portion 18.

Finally, a method of manufacturing the protective seal having the above-described structure will be described. As shown in FIG. 6, this manufacturing method includes an image processing step (step 1), a computer processing step (step 2), and a cutting step (step). 3), fit confirmation process (step 4) and correction work process (step 5), and finally kit making process (step 6)
to go into. That is, the metal exposed surface A of the camera body 2 is photographed by a digital camera, image processing is performed, and information regarding the contour is input to the computer (step 1). Then, the computer processes the contour information and outputs cutting instruction information to the cutting device (step 2). The raw material of the protective seal S has already been set in the cutting device, and cutting information on how to operate the cutting plotter or laser cutter of the cutting device is input to the raw material. Based on the cutting information, the cutting device cuts the protective seal S having the contour shape of the metal exposed surface A from the raw material such as the synthetic resin film or sheet mounted based on the cutting information (step 3). Then, it is confirmed whether or not it is necessary to correct the contour shape by placing the protective sheet on the exposed metal surface of the camera body (step 4). If correction is necessary, it cannot be corrected mechanically, so it is corrected artificially (step 5). If it is not necessary to make a correction, or the corrected protective seal S is pasted on the release paper 17 (step 6). If a major correction is required, re-create the protective seal.

The present invention can be carried out by modifying a part of the above-described embodiment, within the scope of following the fundamental technical idea and not significantly impairing the effects of the invention. For example,
When the pressure-sensitive adhesive applied to the back surface of the protective seal S is made water-soluble and the protective seal S is attached to the exposed metal surface A of the camera body 2, a mist is sprayed on the back surface to give an adhesive force. While slightly lowered, the protective seal S is picked up with tweezers and attached. Then, the protective seal S can be displaced on the exposed metal surface A, which facilitates the positioning of the protective seal S.

Further, when the protective seal S is cut out from the cutting device, the raw material stuck on the release paper 17 is cut and output as a protective sheet kit 19 in which the protective seal S is stuck on the release paper 17. You can also do it. Further, when the contour shape of the protective sheet is to be corrected, the adhesive surface applied by the sheet at the time of mold matching can be easily performed by reversing the glue surface by reverse cutting.
Further, when a protective sheet that straddles a curved portion or a bent portion of a camera is produced, by putting the produced protective sheet on the relevant portion and marking the protective sheet, the contour shape can be easily produced or modified. .

[0029]

As described in detail above, in the camera according to the first aspect of the present invention, the exposed metal surface of the camera body is not damaged even if a small external force is applied to the exposed metal surface.
The camera body can be protected and the appearance of the camera can be kept as new. According to the second aspect of the present invention, since the protective seal is preliminarily cut so as to have a contour having substantially the same shape as the exposed metal surface of the camera body, the work efficiency of attaching the protective seal to the exposed metal surface can be significantly improved. It will be possible.

According to a third aspect of the invention, a plurality of types of the protective seal are
Since the sticking position on the camera body is shown and sticking is performed on the release paper, it is possible to further improve the work efficiency. According to the fourth aspect of the present invention, the protective seal is provided with the cutout contour portion corresponding to the outer shape of the camera component projecting from the exposed metal surface, and the cutout contour portion is provided with the cutout portion.
