Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a camera for both panoramic and stereoscopic photography that can take panoramic photographs (wide-angle photographs) and stereoscopic photographs (stereoscopic photographs) with simple operations. It is something.

(Prior Art) Conventional panoramic cameras and stereo cameras were each dedicated special cameras.

(Problem to be solved by the invention) Therefore, conventionally, when you want to take both panoramic photos and stereo photos, for example in the mountains,
A dedicated camera is required for each, but each camera is large and heavy, making it inconvenient to transport and handle.

Furthermore, since these dedicated cameras are special cameras, they are extremely expensive, and it has been difficult for general users to own both.

The object of the present invention is to provide a panoramic and stereoscopic camera that can be used both as a panoramic camera and a stereoscopic camera by exchanging lenses and simple operations.

(Means for Solving the Problems) In order to achieve the above object, the panoramic photography/stereo photography camera of the present invention is capable of selectively attaching a monocular lens for panoramic photography and a compound eye lens for stereo photography. In an interchangeable lens camera, in front of the photosensitive material in the center of the darkroom,
The light shielding plate is characterized in that it is provided so as to be freely raised and lowered into a substantially vertical upright position and a laid down position which is substantially parallel to the bottom plate or top plate in the darkroom.

(Function) When taking stereo photographs, attach a compound lens for stereo photography and raise the light-shielding plate in the center of the dark room. Also, if necessary, set the light shielding plates on both the left and right sides to the use position.

Then, the light-shielding plate prevents the photosensitive material from fogging due to diffused reflection from the other optical system in the dark room.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows the external appearance of the camera. A mounting frame 2 for a lens plate 3 is provided on the front of the camera body 1.
Compound lenses 4, 4 for stereo photography are attached.

When taking a panoramic photograph, instead of the lens plate 3, a lens plate (not shown) to which a monocular wide-angle lens (not shown) is attached is attached to the lens plate mounting frame 2.

Reference numeral 5 denotes a focal length adjustment knob, and when this knob is rotated, the mounting frame 2 moves forward and backward by the action of a screw, and the distance between the lens and the photosensitive material can be adjusted.

6 is a release, which is connected to a shutter device provided for each lens.

Reference numeral 7 denotes a viewfinder, in which a frame (not shown) corresponding to the angle of view for panoramic photography and stereoscopic photography is drawn, making it convenient for photographing.

Reference numeral 8 denotes a rangefinder, and the attachment frame 2 moves forward and backward as the focal length adjustment knob 5 is rotated, and in conjunction with this movement, the rangefinder is operated.

9 is a film winding knob for winding and
It is now possible to rewind.

FIG. 2 is a perspective view of the camera seen from the back with the camera back 10 opened.

The back cover 10 is provided with a film presser 10a. A frame 12 as shown in FIG. 3 is removably fitted in the darkroom 11 of the camera.

As shown in FIG. 3, a pair of left and right central light-shielding plates 13 made of metal plates are pivotally attached to the center of the bottom plate 12a of the frame 12 with a support shaft 15. It is biased by an opening/closing spring 16 attached to the opening/closing spring 15, and is stopped at an upright position in contact with an upper stopper 17.

When the central light-shielding plate 13 is in the laid-down position, a part of its upper edge is engaged with a protrusion 18a of a stopper 18 provided on the bottom plate 12a of the frame body 12.

One end of the stopper 18 is pivotally supported on the bottom plate 12a of the frame 12 by a support shaft 18b, and an upwardly bent piece 18c at the other end.
are pulled inward by a spring 19.

Below the protruding piece 18a of the stopper, there is a protruding piece 1
A supporting piece 18d is provided which is longer than 8a and bent into a U-shape in the same direction.

The support piece 18d has a side portion that is attached to the bottom plate 12a of the frame body 12.
The stopper 18 is held between the free ends of the metal plates 20 fixed to the metal plate 20, and prevents the stopper 18 from being pulled upward when a part of the upper edge of the central light-shielding plate 13 is hooked onto the projecting piece 18a.

The side light shielding plate 14 is attached to the side plate 12b of the frame body 12,
It is rotatably attached via a support shaft 21 and biased toward the film side by a spring 22, and a stopper 23 provided on the bottom plate 12a of the frame body 12 just in front of the film allows the film surface to close to the side light shielding plate. This prevents it from being damaged by the edges of 14.

To place the side light shielding plate 14 in a non-use position, the side light shielding plate 14 is rotated so as to come into close contact with the side plate 12b, and fixed by a plate spring 24 provided on the bottom plate 12a of the frame body 12.

Further, the lower part of the side light shielding plate 14 has a notch,
When the tip of the plate spring 24 is pressed with a fingertip or the like, rotation of the side light shielding plate 14 is not hindered.

To use the camera of the present invention as a panoramic camera, attach a lens plate (not shown) to which a monocular wide-angle lens is attached to the mounting frame 2, fold down the central light-shielding plate 13 in the darkroom, and open the frame 12. Bottom plate 12
A part of the upper edge of the central light shielding plate 13 is locked to the protruding piece 18a of the stopper 18 provided at the bottom plate 1 of the frame 12.
Further, the left and right side light shielding plates 14 are tilted toward the side plate 12b, and fixed by plate springs 24.

Then, the light shielding plate becomes inoperative in the darkroom, making it possible to take a panoramic photo.

To use it as a stereo camera, attach the lens plate 3 with a compound eye lens for stereo photography.
Attach it to the mounting frame 2.

In addition, in order to prevent fogging of the film due to diffused reflection from other optical systems, etc., a central light shielding plate 1 in the darkroom is installed.
Let 3 stand up.

There are two types of compound lenses for stereo photography: those with a gap of 65 mm and those with a gap of 80 mm between the left and right lenses.
The 65mm lens is effective for taking close-up shots, and the 80mm is effective for taking long-distance shots.

When the gap between the left and right lenses is 65 mm, if the left and right side light-shielding plates 14 are further used, rational photography is possible without wasting film due to the angle of view.

When the distance between the left and right lenses is 80 mm, there is no need to use the left and right side light shielding plates 14 due to the angle of view.

(Modified example) The light shielding plate etc. provided inside the frame in the example,
It may be provided directly inside the darkroom without using a frame.

Although there are two central light shielding plates in the embodiment, there may be one central light shielding plate.

Moreover, the central light-shielding plate may be pivotally attached to the frame or the top plate of the darkroom.

(Effects of the invention) It is convenient because a single camera can be used both as a panoramic camera and a stereo camera, and in addition to the camera, only an interchangeable lens is required. Easy to carry.

Since only a simple device is installed, different kinds of photographs can be taken economically.

Cameras are not limited to roll film types.
It may also be a large dry plate type camera.
