Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaged stereo viewer, and more particularly to the structure of a stereo viewer for stereoscopically viewing stereo photographs.

0002

[Prior Art] A stereo viewer is a device that observes a subject three-dimensionally by viewing two left and right photographs of the same subject taken with a camera at different positions through binocular lenses. is created by photographing with a dedicated stereo camera equipped with two photographing lenses, or by photographing with a single camera at different positions.

[0003] FIG. 6(a) shows the external appearance of the above-mentioned dedicated stereo camera. Two photographic lenses 4 and 5 are arranged. Then, by pressing the shutter button 3, the subject positioned in the finder 2 is simultaneously photographed on the film placed in the camera body 1 through the photographic lenses 4 and 5. The subject will be imprinted on the two images.

FIG. 6(b) shows the configuration of a conventional simple stereo viewer, in which two stereo photographs 7 printed from the above-mentioned film onto photographic paper are mounted on a photograph holder 6a of the viewer main body 6. is inserted, and binocular lenses 8a, 8 are inserted so as to observe this stereo photograph 7 at a clear viewing distance.
b is provided. Therefore, if the stereo photograph 7 is viewed through the binocular lenses 8a and 8b, the subject can be observed as a three-dimensional image.

[0005]

[Problem to be solved by the invention] By the way, the above figure 6 (
Since the conventional stereo viewer shown in b) is handled separately from the stereo camera shown in FIG. There was a problem in that it was not possible to do so, and the user felt uncomfortable.

Furthermore, since the stereo viewer is manufactured separately from the camera, there is a problem in that it requires its own manufacturing cost and increases the burden on the user.

The present invention has been made in view of the above-mentioned problems, and its object is to provide a packaged stereo viewer that allows stereo photographs to be easily observed and that can reduce manufacturing costs.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a main body case formed in a box shape and having a space for storing a stereo photograph, and a lid that is placed over the main body case. A holder part for standing and positioning the stereo photograph is provided on one side of the box-shaped main body case, and a binocular lens is provided on the other side facing the holder part, and the binocular lens is placed in the holder part. The stereo photograph is tilted so as to face the vertical center of the photograph.

[0009]

[Operation] According to the above structure, a stereo photograph with a photographic subject printed thereon can be stored in the main body case and packaged by closing the lid, and the main body case and the lid can function as a package. On the other hand, if you remove the lid, insert the stereo photo into the holder so that it stands up, and look at the stereo photo through binocular lenses, you can observe the stereo image and function as a stereo viewer.

0010

[Example] Fig. 1 shows the configuration of a stereo viewer that also serves as a package according to an example. It is formed in a size that can accommodate a plurality of stereo photographs 7. This main body case 10 is covered with a lid 11 which is slightly larger than this case 10 and made of the same material as the main body case 10. Inverted trapezoidal notches 12 are formed on the left and right sides of the main case 10 so that the stereo photograph 7 can be easily inserted and removed, and an anti-reflection film is attached to the inner surface of the main case 10 to prevent light reflection. (or may be painted black).

Further, a holder part 14 for holding the stereoscopic photograph 7 upright is formed on the rear side of the main body case 10, and this holder part 14 has a structure in which pieces projecting from the left and right sides in parallel to the rear side. shall be. Therefore, as shown in FIG. 2, the rear side of the main body case 10 and the holder part 14
The stereo photograph 7 can be held between the protruding pieces. On the other hand, binocular lenses 15a and 15b made of plastic material are provided on the front side of the case opposite to the rear side of the holder part 14.
is attached, and the stereo photograph 7 set in the holder part 14 by these binocular lenses 15a and 15b is
can be set at a distance of clear vision (approximately 25 cm).

Furthermore, as shown in FIG. 3, the front side of the binocular lens 15 and the rear side of the holder part 14 in the main body case 10 are not perpendicular to the bottom surface but are inclined at a predetermined angle. That is, when the front and rear sides are tilted, the position at which the stereo photograph 7 is viewed by the binocular lens 15 moves upward. It is tilted until it points toward the center. In this case, only the front surface of the binocular lens 15 can be tilted to face the center of the stereoscopic photograph 7.

In this embodiment, as shown in FIG. 5, the binocular lenses 15 are formed in the shape of a varifocal magnifying glass so that the thickness differs in the vertical direction, so that anyone, regardless of age, can take a stereo photograph 7 clearly. You can focus at viewing distance. That is, as shown in the figure, the thickness of the binocular lens 15 is Acm, which is suitable for young people with a clear vision distance of about 25cm.
The lens is formed so that it changes continuously from Bcm to a thickness Bcm suitable for elderly people with a clear vision distance of about 50cm, with young people using the upper side of the lens and elderly people using the lower side of the lens.

According to the above structure, as shown in FIG. 3, the main case 10 is used as a package with the lid 11 closed, and the main case 10 stores stereo photographs completed in a photo lab or the like. It can then be handed over to customers, etc. On the other hand, the user who received the above package will receive the lid 1.
1, take out the stereo photo 7, and attach it to the holder part 14.
By setting the stereo photograph 7 in (FIG. 2), the stereo photograph 7 can be viewed through the binocular lens 15 as shown in FIG. Therefore, the user can easily enjoy stereoscopic photography without having to purchase or take out a separately prepared stereo viewer as in the past. Further, as described above, since the stereo viewer of the present invention is configured to double as a package made of paper material or the like, it has the advantage that it can be manufactured at low cost.

In the above embodiment, the lid 11 is simply placed over the main body case 10, but this lid 11 covers the main body case 10.
A locking mechanism consisting of a claw and a groove that engages with the claw may be provided on the contact surface between the main body case 10 and the lid 11 so that the main body case 10 and the lid 11 are firmly fixed when placed on the cover.

[0016] Furthermore, the binocular lens 1 of the main body case 10 is
5 may be formed entirely of a plastic material including the binocular lenses 15, and in this case, the process of attaching the lenses can be simplified.

[0017]

[Effects of the Invention] As explained above, according to the present invention,
It consists of a box-shaped main case that has a lid and stores a stereo photograph, a holder part for holding the stereo photograph is provided on one side of the main case, and a binocular lens is provided on the other side facing the holder part. At the same time, this binocular lens is tilted so as to face the vertical center of the stereo photograph, so it functions as a package for wrapping the stereo photograph, and by removing the lid and setting the stereo photograph in the holder, It can function as a viewer, allowing users to easily observe stereoscopic images created by stereo photography.

Furthermore, since the stereo viewer is manufactured using a package such as paper and has a structure that simultaneously achieves the package function, there is an advantage that the manufacturing cost of the stereo viewer can be reduced.
