[Detailed Description of the Invention] Sh1↓mMe1 The present invention relates to a camera, and more specifically, it records photographic data such as aperture value, shutter speed, and focal length of the lens used at the time of photographing. The present invention relates to a camera equipped with a means for imprinting photographic data that can be imprinted.

Currently, the shooting date can be imprinted on the film at 35m.
m cameras are widely available. In such cameras, the shooting date is generally imprinted on the image area of the film. In this way, when the photographing date is imprinted on the image area of the film, when it is developed and printed on photographic paper, the photographing date will also appear in the image. Therefore,
When you look at the photo, you can see the date it was taken, which is convenient because you don't have to write the date on the photo or write the date on each photo when pasting it in an album.

On the other hand, there is a problem in that the part of the image where the shooting date is stamped is erased.

Furthermore, in order to record the shooting situation, conventionally, after printing on photographic paper or making a slide film, the shutter speed and focal length of the lens used are written in the margins of the album, the blank space of the film holder, and the frame of the slide film. and the brightness and type of filter used.

That is, in the case of a slide film as shown in FIG. Brightness and speed, for example, 20h+m, f5.6.1/
It is written as 125. Furthermore, the type of filter to be used is written as PL, for example, below the area where the focal length, brightness, and shutter speed of the lens are written, as shown by reference numeral 20.

The above-mentioned record of the shooting situation can be recorded in a notebook at the time of shooting, and then copied to the slide film frame that has been photo processed and turned into a slide film, the margin around the photo printed on photographic paper, or to an album. is necessary. However, copying has the problem that mistakes may occur.

Therefore, it is possible to imprint the shutter speed, the focal length and brightness of the lens used, and the type of filter used in the image area of the film in the same way as the shooting date is imprinted on the film. Imprinting data onto the image area of the film is undesirable because it erases only that part of the image and spoils the impression of the image.

B… ± Overload, where the present invention is recorded in the notebook for a record of the shooting status, it is not necessary to copy it after printing or after photography, and the shooting data is captured into the film video area. The aim is to provide a camera that does not impair the impression of images.

That is, according to the present invention, at least one of the aperture value, shutter speed, focal length of the lens used, brightness of the lens used, and type of filter used is set outside the sprocket hole of the film. To provide a camera characterized in that it is provided with a photographed data imprinting means capable of imprinting upon photographing.

When using a camera configured as described above, when shooting, simply setting the shooting data manually or automatically in the shooting data imprinting means and pressing the camera's shutter button will print the image onto the outside of the sprocket hole of the film. aperture value,
At least one of the shutter speed, the focal length of the lens used, the brightness of the lens used, and the type of filter used can be captured during photographing.

[Nagai Shoza] As described above, by using the shooting data imprinting means, at least one of the aperture value, shutter speed, focal length of the lens used, brightness of the lens used, and type of filter used is printed on the outside of the sprocket hole of the film. If it were possible to imprint data at the time of shooting, there would be no need to record the shooting data in a notebook at the time of shooting to record the shooting situation and transcribe it after photo processing or printing, and there would be no copying errors caused by copying. . Further, since the above-mentioned photographic data is imprinted on the area outside the sprocket hole of the film, the photographic data is not imprinted on the image area of the film and spoils the impression of the image.

Embodiments of the camera according to the present invention will be described below with reference to the accompanying drawings.
