Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a disposable camera called a film with a lens or a film-integrated camera capable of taking a picture easily, and particularly to a disposable normal camera capable of taking a normal picture and a panoramic picture. / Regarding the panorama switching camera.

[0002]

2. Description of the Related Art A normal-size photograph taken with a normal lens and a panoramic-size photograph taken with a wide-angle lens have different photographing ranges and photographing purposes, and are conventionally photographed by separate cameras. . However, a normal / panoramic switching camera with a switching device that can take normal and panoramic pictures with one camera has been developed. This type of camera is a generalization of panoramic photography that was thought to be for some enthusiasts, but it was expensive because it was equipped with both normal and wide-angle lenses.

On the other hand, the price of cameras has been rapidly reduced, and finally, a disposable camera called a film with a lens or a film-integrated camera has been developed, and there is strong demand for it. At present, in addition to a normal size disposable camera. A disposable camera equipped with a panoramic wide-angle lens has also been developed. Furthermore, disposable cameras that can switch between normal size and panorama size have also appeared.

[0004]

Since the normal / panorama switching disposable camera does not essentially have a lens exchanged, the following problems have been pointed out. It is not an original panoramic photo because the negatives taken are cut off at the top and bottom and the remaining landscape is enlarged to provide a panoramic photo. The image quality cannot be kept in good condition because the image is expanded horizontally for panorama more than originally planned.

Further, there is an essential drawback in that the merit that the disposable camera is inexpensive is lost. Further, in developing, it takes time and effort to cut and remove the upper and lower sides of a normal size photograph and enlargement work, and there is a drawback that the cost of the taken panoramic photograph becomes high.

Therefore, an object of the present invention is to provide a disposable normal / panoramic switching camera having a structure in which a wide-angle lens is used in a conventional normal / panoramic switching disposable camera and the film is exposed in the same range as seen through a viewfinder. It is in.

[0007]

The structure of the present invention for achieving the above object is a disposable lens equipped with a wide-angle lens capable of taking both a wide-angle panoramic photograph and a normal normal photograph with a single camera. In the camera, in the middle box between the wide-angle lens of the camera body and the position where the exposed film is rotated and mounted, a light-shielding plate made of a flexible elongated plate is rotated horizontally to the upper and lower ends of the axis that can be operated from the outside of the camera. The structure is freely installed.

Further, the structure of the finder of the present invention has a structure in which transparent slender plates are attached to the upper and lower parts of the finder, which are colored so as to clearly indicate the photographable ranges of panoramic photographs and normal images, or In addition to being equipped with a colored transparent elongated plate that shows the shooting range,
The light-shielding plate is rotatably mounted, and a field-of-view control plate composed of a flexible elongated plate is rotatably attached to the upper and lower ends of the finder on a shaft that can be operated from the outside of the camera.

[0009]

According to the normal / panorama switching disposable camera having the above-mentioned structure, the exposure range of the panorama in which the upper and lower parts are removed is displayed in the finder by changing the switching lever provided on the outside of the camera from the normal to the panorama. Since the light-shielding plate covers the upper and lower edges of the exposed surface of the film as a baffle plate and limits the exposure range, a photo taken with one wide-angle lens has a normal size shooting width and a panorama size shooting width. Will be exposed to the film.

EXAMPLES A disposable normal / an embodiment of the present invention
The exploded front view of the panorama switching camera is shown in FIG. 1, and the viewfinder portion is shown in FIG.

Disposable normal / panoramic switching camera 1
Reference numeral 0 includes a camera frame 1, a wide-angle lens 2, a normal / panorama switching device 3, a finder 4, a shutter 5, a film mounting section 6, a film winding section 7, and a winding operation section 8. The camera frame 1 is composed of a normal horizontally long rectangular parallelepiped, has a wide-angle lens in the center, a film mounting unit and a winding unit on the left and right, and a winding operation unit and a shutter on the winding unit.

In this embodiment, the wide-angle lens 2 is used as the lens. As a result, all the pictures taken will be taken at a wide angle. Even if a wide-angle photograph is developed as it is in the size of a normal photograph, there will be no major complaints to consumers. This is different from the conventional normal / panorama switching single-use camera in which the upper and lower portions of the film shot with the normal lens are deleted and only the narrow portion is enlarged to give a misunderstanding as if it were a panoramic photograph.

The normal / panorama switching device 3 comprises a wide-angle lens 2 and a light-shielding plate 31 made of a flexible elongated plate provided between the exposed film 11 and a shaft 32 which can be operated from the outside of the camera. In this embodiment, the shading plates 31 are laterally fixed to the upper and lower ends of a rotatable shaft 32,
When the shaft is rotated, it rotates horizontally in response to the rotation of the shaft and shields the upper and lower parts of the exposed film from light. The installation position of the shaft 31 is located between the wide-angle lens and the film,
It may be a position where the axis does not appear on the exposed film.
Further, the shape of the light shielding plate 31 may be two flexible horizontally long thin plates separated into upper and lower portions, or may be a single U-shaped thin plate. Further, the light shielding plate 31 does not necessarily need to be fixed to the shaft 32, and may be rotatably fitted, and may be configured to rotate by another forcibly pressing means to shield the film.

In this embodiment, the entire fill is exposed by operating the switching lever during normal shooting to avoid the light-shielding plate 31 that shields the upper and lower ends of the photosensitive film from the film, It is not limited to this.

The finder 4 has a structure in which transparent elongated plates 41 with colors are attached to the top and bottom. The viewfinder of an ordinary disposable camera is a simple aperture having no structure such as glass or lens attached, and has a structure in which it is slightly widened toward the subject. The entire area excluding the transparent elongated plate is the photographing range of the normal photograph, and the range limited by the upper and lower transparent elongated plates shows the photographable range of the panoramic photograph.

In this embodiment, a field-of-view control plate 42 is added to the viewfinder having the transparent elongated plate 41 mounted thereon.
It is a structure provided with. The field-of-view control plate 42 limits the photographable range viewed through the viewfinder to the range of a panoramic photograph, and blinds the same range as the transparent elongated plate 41. The field-of-view control plate 42 is composed of two flexible elongated plate members that shield the upper and lower ends of the finder, and is fixed to a rotating shaft 43 that can be operated from the outside of the camera. Rotation control of the visual fields at the upper and lower ends.

The field-of-view control plate 42 does not necessarily have to be fixed to the shaft 43, but is rotatably fitted in the field-of-view control plate 42, and the field of view is controlled by rotating the field-of-view control plate 42 by using another forcibly pressing means. May be. Further, the shaft 43 of this embodiment is configured to rotate in conjunction with the shaft 32 of the light shielding plate 31, and the shaft 3
The shaft 43 also rotates simultaneously with the rotation of 2. However, the shaft 43 and the shaft 32 do not need to be interlocked with each other, and the rotation direction and the rotation time can be changed respectively.

[0018]

Since the disposable normal / panorama switching camera according to the present invention has the above-mentioned structure, it has the following effects. First, since a wide-angle lens is used as the lens, it is possible to take a normal panoramic picture with one inexpensive disposable camera according to preference. Since a wide-angle lens is always used in this embodiment, a panorama photograph of a sufficiently clear screen can be easily taken by exposing the film by removing the upper and lower edges of the photograph taken with the wide-angle lens from light-shielding and exposing. can do. Further, since it is a wide-angle lens, even if it is developed in the size of a normal photograph as it is, no big complaint is made to the consumer. In use, the changeover lever provided on the outside of the disposable camera is changed from normal to panorama, so that the panorama exposure range with the top and bottom removed is easily displayed in the viewfinder, and the top and bottom edges of the exposed surface of the film are displayed. The light-shielding plate serves as a baffle plate to cover and limit the exposure range. Therefore, there is an advantage that normal size and panoramic size pictures can be enjoyed inexpensively and easily with extremely simple operation. Compared with the conventional structure, there is a drawback that a wide-angle lens is always used, but it is considered that it is an advantage that can be fully evaluated because it is a cheap, simple and durable structure.
