DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide mount for mounting a slide film, and more particularly to a stereo slide mount for mounting a pair of stereo slides.

[0002]

2. Description of the Related Art An example of a conventional stereo slide mount will be described with reference to FIG. The stereo slide mount 1 shown in FIG. 1 is made of paper, and the upper half is bent toward the front at the position of the folding line 2 in the middle of the upper and lower portions, so that the upper half surface mount frame 3 and the lower half rear surface are formed. It is formed so as to adhere to the side mount frame 4.

The front side mount frame 3 and the rear side mount frame 4 have windows 5L, 5R, 6
L, 6R are stamped out, and the windows are arranged vertically symmetrically with the folding line 2 as the axis of symmetry.

[0006] Reference lines 7, 8 as targets of the vertical position of the slide film are printed above and below the lower windows 6L, 6R, and the left slide of a pair of stereo slides cut for each frame is moved to the lower left. Then, the right side slide is bonded to the lower right window 6R, and then the upper and lower mount frames 3 and 4 are folded and bonded.

FIG. 5 shows a pair of left and right stereo slides 9L and 9R photographed by a conventional stereo camera. The left end of the left slide 9L and the right slide 9R are determined by the difference in the field of view of the left and right photographing lenses of the stereo camera. The right end of the screen has an image portion that does not overlap between left and right slides. The non-overlapping portions 10L and 10R do not form a stereoscopic image when viewed with a stereo slide viewer. As shown in FIG. 6, when viewed with both eyes, the boundary between the overlapping portion and the non-overlapping portion has the other window. The edge will look like a vertical line.
Therefore, in order to prevent this, the width of the windows 5 and 6 of the stereo slide mount 1 is formed smaller than the screen size of the slide 9 to shield the non-overlapping portion 10 described above.

In order to obtain an appropriate three-dimensional effect, when the slide is mounted on the stereo slide mount, the foreground subject is positioned at substantially the same position in each of the left and right windows, and the distance between the left and right slides is adjusted. It is necessary to adjust the front-back position of the binocular image of the subject.

[0007] In a stereo slide photographed by a conventional stereo camera, the optimum left-right distance varies depending on the photographing distance of the foreground subject. If the right-left distance adjustment is incorrect, the stereoscopic effect intended by the photographer cannot be obtained. In addition, as the shooting distance becomes shorter, the above-described non-overlapping portions 10L and 10R increase. Therefore, stereo slide mounts having several types of window widths according to the shooting distance are prepared.

[0008]

The applicant of the present invention has proposed a stereo camera in which the center distance between the left and right photographing lenses can be adjusted in order to solve the drawbacks of the conventional stereo camera (Japanese Patent Application No. Hei 6 (1994) -106). 252229). This stereo camera can correct the parallax of the left and right screens and reduce the left and right non-overlapping parts as much as possible irrespective of the shooting distance of the subject. It became possible to mount.

However, since the conventional stereo slide mount does not serve as a reference for the distance between the left and right slides, there is a possibility that the stereo mount is improperly mounted and the three-dimensional effect is reduced.

Also, a parallax correction function capable of reducing non-overlapping portions on the left and right sides by reducing the width in the width direction of the screen because the width of the window is narrower than that of the real screen to block non-overlapping portions on the left and right screens. There is a disadvantage that the features of the stereo camera cannot be fully exhibited.

Therefore, there is a technical problem to be solved in order to provide a stereo slide mount which mounts a stereo slide photographed by the above-mentioned stereo camera without reducing the stereoscopic effect at the time of photographing and eliminates screen loss. Problems arise, and an object of the present invention is to solve the above problems.

[0012]

DISCLOSURE OF THE INVENTION The present invention is proposed to achieve the above-mentioned object, and has a slide in which a peripheral portion of a slide film is sandwiched on both front and back sides by a pair of front and back mount frames provided with rectangular windows. a mount, in the stereo slide mount which is adapted to hold the two pieces of slide films juxtaposed two windows, the upper
