DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereo viewer that also serves as a package, and more particularly to the structure of a stereo viewer for stereoscopic observation of stereo photographs.

[0002]

2. Description of the Related Art A stereo viewer is for stereoscopically observing a subject by viewing two left and right photographs of the same subject, which are taken with the camera at different positions, with a binocular lens. Is created by a method of shooting with a dedicated stereo camera equipped with two shooting lenses, or a method of shooting by changing the position with one camera.

FIG. 6 (a) shows the appearance of the above-mentioned dedicated stereo camera. This stereo camera has a distance of about 70 mm on the front surface of the camera body 1 provided with a viewfinder 2 and a shutter button 3. Therefore, two taking lenses 4 and 5 are provided. Then, the subject positioned by the viewfinder 2 is simultaneously photographed on the film arranged in the camera body 1 via the photographing lenses 4 and 5 by pressing the shutter button 3, and the film is captured from different angles. The two captured subjects will be captured.

FIG. 6 (b) shows the structure of a conventional simple type stereo viewer. Two stereo photographs 7 printed on the photographic paper from the above film are placed in the photographic holder portion 6a of the viewer main body 6. Is inserted, and the binocular lenses 8a and 8a, 8 are used to observe the stereo photograph 7 at a clear viewing distance.
b is provided. Therefore, if the stereo photograph 7 is viewed with the binocular lenses 8a and 8b, the subject can be observed as a three-dimensional image.

[0005]

However, FIG.
Since the conventional stereo viewer of (b) is handled separately from the stereo camera of FIG. (A), a stereo photograph 7 printed on photographic paper is created, and even if it is received, it can be immediately observed as a stereoscopic image. However, there is a problem in that it gives the user a feeling of trouble.

Further, since the stereo viewer is manufactured separately from the camera, there is a problem in that its own manufacturing cost is required and the burden on the user is increased.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a package / stereo viewer capable of easily observing a stereo photograph and reducing the manufacturing cost.

[0008]

In order to achieve the above object, the present invention provides a box-shaped main body case having an open upper surface for accommodating a plurality of stereo photographs, and a main body case. And a detachable cover, a holder portion for standing and positioning the stereo photograph is provided on one side surface of the box-shaped body case, and a binocular lens is provided on the other side surface facing the holder portion. The binocular lens is characterized in that it is tilted so as to face the central part in the vertical direction of the stereo photograph placed on the holder part.

[0009]

According to the above construction, the stereo picture on which the subject is printed can be stored in the main body case and closed by closing the lid, and the main body case and the lid can function as a package. On the other hand, by removing the lid and inserting the stereo picture in the holder so as to stand up and looking through the stereo picture through the binocular lens, a stereoscopic image can be observed and it can function as a stereo viewer.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows the structure of a stereo viewer that also serves as a package according to an embodiment. The main body case 10 is a box type made of a paper material or a plastic material, and a set of two photographs is printed. The stereo photograph 7 is formed in a size capable of storing a plurality of sets. The body case 10 is covered with a lid 11 that is slightly larger than the case 10 and is made of the same material as the body case 10. In addition, inverted trapezoidal cuts 12 are formed on the left and right side surfaces of the body case 10 so that the stereo photograph 7 can be easily taken in and out, and an antireflection film for preventing light reflection is attached to the inner surface of the body case 10. Is preferable (or black coating may be applied).

Further, a holder portion 14 for standing and holding the stereo photograph 7 is formed on the rear side surface of the main body case 10, and the holder portion 14 is provided with protruding pieces parallel to the rear side surface from the left and right side surfaces. And Therefore, as shown in FIG. 2, the rear surface of the main body case 10 and the holder portion 14 are
The stereo photograph 7 can be sandwiched between the protruding pieces.
On the other hand, the binocular lenses 15a and 15b made of a plastic material are provided on the front side surface of the case facing the rear side surface of the holder portion 14.
A stereo photograph 7 attached to the holder 14 by the binocular lenses 15a and 15b.
Can be set to the distance of clear vision (about 25 cm).

Further, as shown in FIG. 3, the front side surface of the binocular lens 15 and the rear side surface of the holder portion 14 in the main body case 10 are tilted at a predetermined angle from the bottom surface instead of being vertical. That is, when tilting the front and rear sides, will be the binocular lens 15 See stereograph 7 position moves upward, in the embodiment binocular lens 15 as shown in FIG. 4 is a vertical stereograph 7 It is tilted to a position facing the center. In this case, it is also possible to incline only the front surface of the binocular lens 15 so that the center portion of the stereo photograph 7 faces.

In the embodiment, as shown in FIG. 5, the binocular lens 15 is formed in a variable loupe shape so that the thickness of the binocular lens 15 is different in the vertical direction. You can focus on the viewing distance. That is, as illustrated, the binocular lens 15
Is formed so that the thickness Acm for young people with a clear vision distance of about 25 cm changes continuously from the thickness Bcm for elderly people with a clear vision distance of about 50 cm. The old man is supposed to use the lower side of the lens.

According to the above construction, as shown in FIG. 3, the main body case 10 is used as a package in a state where the lid 11 is closed, and the main body case 10 accommodates a stereo photograph produced at a developing place or the like. You can then hand it over to your customers. On the other hand, the user who receives the above-mentioned package is
Remove 1 and take out the stereo photo 7.
By setting the stereophotograph 7 in FIG. 2 (FIG. 2), the stereophotograph 7 can be seen from the binocular lens 15 as shown in FIG. Therefore, the user can easily enjoy a stereoscopic photograph without purchasing or taking out a stereo viewer prepared separately as in the past. Further, as described above, the stereo viewer of the present invention has a structure that it also serves as a package made of a paper material or the like, so that there is an advantage that it can be manufactured at low cost.

In the above-described embodiment, the main body case 10 is simply covered with the lid 11, but the lid 11 is used as the main body case 10.
A locking mechanism having a combination of a claw and a groove that engages with the claw may be provided on the contact surface of the main body case 10 and the lid 11 so as to be firmly fixed when covered with the claw.

Further, the binocular lens 1 of the main body case 10
The front side surface provided with 5 may be entirely formed of a plastic material including the binocular lens 15, in which case the lens mounting process can be simplified.

[0017]

As described above, according to the present invention,
It consists of a detachable lid and a box-shaped main body case with an open top to store multiple stereo photographs. A holder portion for standing the stereo photograph is provided on one side of the main body case. A binocular lens is provided on the other side opposite to, and the binocular lens is tilted so as to face the central portion in the vertical direction of the stereo photo, so that it functions as a package for packaging the stereo photo.
By removing the lid and setting the stereo picture on the holder part, it can function as a stereo viewer, and the user can easily observe the stereoscopic image by the stereo picture.

Further, since it is manufactured by using a package of paper or the like and the package function is achieved at the same time,
There is an advantage that the manufacturing cost as a stereo viewer can be reduced.
