Abstract

PURPOSE:To use one camera for many purposes by providing plural photosensitive bodies and an optical means which exposes these photosensitive bodies simultaneously. CONSTITUTION:When a photographer directs the camera to an object and depresses a shutter button 7 after loading instant revealing photodetectors 8 and 9, diaphragms 15 and 16 are narrowed on a basis of information of the quantity of light obtained from a photodetector 14, and shutter curtains 17 and 18 are opened at the moment when narrowing is completed, and instant revealing photosensitive bodies 8 and 9 are exposed to light only for a time corresponding to information of the quantity of light. When exposure is terminated, instant revealing photosensitive bodies 8 and 9 are pulled out from pulling- out holes 10 and 11, and developing and fixing actions advance on photosensitive surfaces of instant revealing photosensitive bodies 8 and 9 to obtain color photographs. Thus, simultaneously exposed photographs are obtained on two instant revealing photosensitive bodies 8 and 9 by one depressing operation of the shutter button, and the same photographs are presented to two persons just after photographing.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a photographic machine.

BACKGROUND TECHNOLOGY In general, Polaroid photography is well-known as an instant photoreceptor type of photography because it involves direct exposure to the photoreceptor, development and fixing, and there is no intervening film that serves as the original material for reproduction. , is a trademark of Polaroid Company, USA.
This photo was taken with an instant-effect camera that uses an instant-effect photoreceptor manufactured by the same company, and the photographic paper was pulled out after the photo was taken, and a few minutes later it automatically became a color print. Therefore, conventionally, when taking instantaneous photographs, only a single photoreceptor can be exposed for each exposure, which makes it difficult to distribute such photographs to multiple people at the same time. ,
Only the losers of the person who wants to distribute the tickets must be photographed one after another.

Embodiment FIG. 1 is a front view of a camera 1 according to an embodiment of the present invention.
FIG. 2 is a simplified cross-sectional view of the photograph W11.

The front of the housing 2 of the camera 1 is provided with two left and right lenses 3.4, a finder 5, and a flash 6. A shutter button 7 is provided on the top, and a photoreceptor 8 is provided on the bottom. Extraction holes io and 1t of 9° are provided. A photodetector 14 is provided at one corner of the facing 5. On the other hand, inside the camera 1, immediately after the two left and right lenses X'3.4, photoreceptors 8 and 9 are loaded in the position 1 where the lens 3.4 focuses through the aperture 15.16.
Immediately in front of the photoconductors 8 and 9 on the lens side are shutters 1 and 1, respectively.
17 and 18 are arranged.

When taking pictures, the photographer selects the photoreceptor 8,
In this embodiment, both are stacked sea F-shaped photoreceptors in an instantaneous camera. After loading the instantaneous photoreceptor 8.9, the photographer presses the shutter button 7 toward the subject, and the photodetector 1
Based on the information on the amount of light obtained from the above, the diaphragm 15, 16 is appropriately narrowed down, and the moment the diaphragm is completed, the shutter base 17, 18 is closed, and the instantaneous photoreceptor is closed for a time commensurate with the information on the amount of light. 8 and 9 are exposed. When the exposure is completed, the instantaneous photoreceptors 8 and 9 open the q1 exit hole 10.1.
1, respectively. A developing and fixing reaction proceeds on the photosensitive surface of the instantaneous photoreceptor 8.9 that has been pulled out, and a color print is formed after a few minutes.

In this way, by pressing the shutter button 7 once, it is possible to obtain a photograph in which the two instantaneous photoreceptors 8.9 are exposed at the same time, and the same photograph can be handed to two people immediately after the photograph is taken. Can be done.

As an embodiment of the pond of the present invention, the camera 1 shown in FIG.
Assume that one of the photoreceptors 8 and 9 is an instantaneous photoreceptor and the other is a film. This film is typified by tape film, and is a general term for slide film, black and white film, infrared all film, tungsten film, etc., and can leave an original plate that can be reproduced. In this case, the following effects can be obtained.

(,) Because the instant photoreceptor allows you to check the finish at the shooting location, it is possible to prevent problems such as poor focus, focus, or exposure, camera shake, failure of 7-ray setting, or discrepancies in the flashing time between 7-shot and 7-shot shots, etc. 70 nt〃
It is possible to prevent photographing errors such as the reflection of the photographer's shadow on the surface of the lath when photographing through the lath.

(b) Immediate expression The drawbacks of photoreceptors include the inability to reproduce, blurring due to poor graininess, and easy deterioration over time, that is, fading, by using a film on one side of the photoreceptor. Not only does this solve the problem, but it also improves economic efficiency by making more prints, and it is also possible to obtain different styles of photographs from a single original by enlarging them to any size and printing them in the desired color tone. can.

(e) In a camera using prior art film,
Photographers with the ability to record the date and time are commercially available, but according to this embodiment, necessary information such as the date, time, weather, and location of the photograph can be immediately displayed on the back of the photoreceptor. By recording the information, it is possible to obtain more information than with conventional techniques, and it is also easier to compare the photographs taken from the film later.

(d) When two people take a photo, you can hand the photo taken using the instant photoreceptor to the other person and spend 10 minutes developing and printing the film you have on hand, thereby saving you the trouble of sending the photo to the other person.

(e) It is possible to distribute instant photoreceptor photographs at the shooting location and later distribute clear photographs printed from the film.

As a further embodiment of the present invention, it is assumed that the photoreceptors 8 and 9 of the camera 1 shown in FIG. 1 are made of films having different photosensitive characteristics depending on their coloring methods, sensitivities, and the like. Films are variously classified according to their photosensitive properties as described above and are commercially available.

Therefore, in this embodiment, films with different color development methods are used, such as a negative film for one photoreceptor and a slide film for the other photoreceptor. By doing this, the negative film can be printed on photographic paper and the slide film can be reproduced by projection using a projector, allowing for different ways of enjoying it.

Next, films of the same type but with different sensitivities are used, for example, a high-sensitivity film of ASA400 is used for one photoconductor, and a medium-sensitivity film of ASAloo is used for the other photoconductor. Generally, film sensitivity and graininess have a contradictory relationship; therefore, the higher the sensitivity, the worse the graininess. That is, when photographing under the same brightness, a high-sensitivity film allows for a faster shutter speed than a medium-sensitivity film, making it suitable for photographing fast-moving subjects and preventing camera shake. Alternatively, by narrowing down the aperture, the depth of field, that is, the in-focus area, can be deepened, which has the advantage of preventing out-of-focus. On the other hand, the sharpness is poor due to poor graininess, making it impossible to express fine detail, making it unsuitable for enlarging.Therefore, in this example, films of the same type but with different sensitivities were used. Therefore, it is possible to make use of only the best of the two contradictory characteristics described above.

FIG. 3 is a simplified cross-sectional view of a photographic device 21 of another embodiment of the invention, which is similar to the photographic device 1 of the embodiment shown in FIG. mark,
