Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention moves a mask that regulates the filming range of a film and a mask that regulates the field of view of a viewfinder at the same time, and divides the short side of the film screen dimension into two horizontally long ones. And a device for taking a panoramic camera photograph by obtaining a screen.

(Prior art) As is well known, one cut of 35mm film is 36 × 24
Millimeters. Conventionally, as shown in FIG.
A half-size camera has been provided which shoots the long side of a screen of × 24 mm and one cut by dividing it into two.

On the other hand, in order to easily obtain a panoramic photograph, a panoramic camera that shoots a screen size of 36 × 12 mm on a 36 × 24 mm screen for one cut of a 35 mm film as shown in FIG. 5 is also provided. ing.

Generally, when trying to obtain a long and narrow panoramic screen with a short side length of 1 and a long side length of 3, a normal 36 × 24 mm screen size camera is used, and the film image is printed on photographic paper. I was trimming when stretching. When trimming, a photograph is made without using the upper and lower sides of the short side of the actually shot film screen.

The panoramic camera shown in FIG. 5 which shoots at a screen size of 36.times.12 mm also shoots by cutting the upper and lower sides of the short side of the film screen. Therefore, an image is created without using the upper and lower sides of the short side of the film screen that can be photographed.

As another method of obtaining a panoramic photograph, there is a panoramic camera in which the length of the long side is lengthened by using two cuts of the length of the long side while keeping the length of the short side as it is. In this case, when the image is stretched to a photograph, the size of the film screen becomes a special size, so that a special enlarger is required.

(Problems to be Solved by the Invention) Conventionally, a method of making a panoramic photograph has been to cut the top and bottom in the short side direction of the screen or to make the screen size special. If trimming is performed at the time of cutting or stretching the upper and lower sides of the short side of the screen, the upper and lower sides of the short side of the film are not used, and half of the film is wasted.

On the other hand, a special camera or enlarger is required to make the film screen size a special size, so there is a problem that normal photograph development and enlargement services are not available, and panoramic photos cannot be enjoyed at low cost. .

(Means for Solving the Problems) In the present invention, a cover for shielding one side is provided in order to divide the short side direction of the film screen into two, and the finder also divides the short side direction into two parts and interlocks with the above-mentioned cover. As a result, a panoramic camera that can effectively use the film was obtained. Further, a panoramic camera which is not affected by aberration around the taking lens system is obtained by moving the taking lens so that the optical axis is located at the center of the screen divided into two parts.

Hereinafter, the present invention will be described with reference to examples.

FIG. 1 is a perspective view of a panoramic camera according to a first embodiment of the present invention.

11 is a screen switching shield that shields half of the film screen 12,
Reference numeral 13 denotes a finder field switching plate for changing the field of view of the finder 14, which is constituted by a shielding portion 13a and a transparent portion 13b. The screen switching shield 11 is a lens barrel 15 having a camera taking lens.
Are connected by a connecting piece 17 to a lens barrel holding plate 16 for holding the lens barrel. Then, the screen switching shielding plate 11 moves around the shaft 18 at the end of the connecting piece 17 as a fulcrum. Then, the finder visual field switching plate 13 connected in the middle of the connecting piece 17 moves in conjunction with it.

FIG. 1 shows a state in which an image is shot on the upper half of the film screen 12. That is, the screen switching shielding plate 11 covers the lower half of the film screen 12, the lens barrel 15 is located at a position corresponding to the upper half of the film screen 12, and the shielding portion 13a of the finder visual field switching plate 13 is the lower half of the finder 14. Is covered.

In order to take a picture in the lower half of the film screen 12, the screen switching shielding plate 11 moves upward with the axis 18 at the end of the connecting piece 17 as a fulcrum, in conjunction with a shirt release mechanism (not shown).
The finder field switching plate 13 connected in the middle moves upward, the shielding portion 13a of the finder field switching plate 13 covers the upper half of the finder 14, and the transparent portion 13b forms the field of view.

FIG. 2 is a perspective view of a panoramic camera according to a second embodiment of the present invention.

21 is a screen switching shield that shields half of the film screen 22,
Reference numeral 23 denotes a finder field switching plate for changing the field of view of the finder 24, which is composed of a shielding part 23a and a transparent part 23b. The screen switching shield 21 is a lens barrel 25 having a camera taking lens.
Are connected by a connecting piece 27 to a lens barrel holding plate 26 for holding the lens barrel. Then, the connection piece is moved by the movement of the screen switching shield 21.
The lens barrel holding plate 26 moves about a shaft 28 at the center of 27 as a fulcrum. Further, in conjunction with the movement of the lens barrel holding plate 26,
The finder field switching plate 23 moves in conjunction with the axis 30 provided at the center of the connecting piece 29 as a fulcrum.

FIG. 2 shows a state in which an image is shot on the upper half of the film screen 22. That is, the screen switching shielding plate 21 covers the lower half of the film screen 22, the lens barrel 25 is located at a position corresponding to the upper half of the film screen 22, and the shielding part 23a of the finder visual field switching plate 23 is the lower half of the finder 24. Is covered.

In order to take a picture in the lower half of the film screen 22, the screen switching shield 21 moves upward in conjunction with a shirt release mechanism (not shown), the connecting piece 27 moves about the axis 28 as a fulcrum, and the lens barrel is held. The plate 26 moves downward, and the lens barrel 25 moves to a position corresponding to the lower half of the film screen 22. Furthermore,
In conjunction with the movement of the lens barrel holding plate 26, the finder field switching plate 23 moves upward with the axis 30 provided at the center of the connecting piece 29 as a fulcrum, and the finder field switching plate 23
a covers the upper half of the viewfinder 24, and the transparent portion 23b forms the field of view.

FIG. 3 is a plan view showing a film photographed by the panoramic camera of the present invention. A to H indicate captured images. 1 shot with a normal 35mm camera
The cuts are formed from the images indicated by A and B. Two cuts of 35 mm width can be obtained from the image obtained by the panoramic camera of the present invention.

The photographing order may be A, B, D, C, E, F, H, G, the screen switching shield and the finder visual field switching plate may be alternately moved by one cut, and the photographing may be performed. , G and the upper half of the film, and moving in the order of H, F, D and B while moving and rewinding the screen switching shield and the finder visual field switching plate.

A commercially available film is used, and the long side of the screen dimension is a dimension conventionally used. 35
When using a roll film for millimeter format, the screen size 36 x 24 mm is the same as 36 mm, 24 mm is divided into two,
The margin is set to 11.5 mm by taking the center of the 1 mm screen. Therefore, the screen size that can be drawn is a long and narrow size of 36 x 11.5 mm. The same applies when a brownie film or a sheet film is used.

(Effect of the Invention) By making the length direction of the film screen the same size as the commercially available size, panoramic photos can be enjoyed inexpensively without the need for a special camera or enlarger, and the film is not wasted. This has the effect of doubling the specified number of shots. Further, as shown in the second embodiment, by linking the screen switching shield and the photographing lens, it is possible to perform photographing using the vicinity of the optical axis of the photographing lens, and there is an effect of not being affected by peripheral aberrations.
