Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for writing photographic data on photographic paper, which is used in combination with a device for printing a film image onto photographic paper. When printing the film image onto photographic paper, the photographic data such as the aperture value, shutter speed, focal length of the lens used, brightness of the lens used, and filter used are stored on the outside of the film's sprocket hole. This invention relates to a writing device for writing on the edges of photographic paper.

Conventional technologyCurrently, the shooting date can be imprinted on the film by 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, and it is convenient because you do not 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 1, after printing on photographic paper or making a slide film, the shack speed and the focus of the lens used are recorded in the margin of the album, the blank space of the film holder, or the mounting part of the slide film. I wrote down the distance, brightness, and type of filter used.

That is, for a slide film as shown in FIG. 1, the focal length of the lens used and the Brightness and shutter speed, for example, 200mm, f5.6.1/1
It is written as 25. Furthermore, the type of filter used is written as PL, for example, as indicated by reference number 20.

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

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

Therefore, the inventor of this application filed the patent application No. 59-67604.
In order to record the shooting situation, there is no need to record it in a notebook at the time of shooting and transcribe it after printing or processing the photo, and there is no need to copy the shooting data into the image area of the film, which may spoil the impression of the image. I suggested a camera that doesn't have one.

That is, the inventor of the present application imprints 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 on the outside of the sprocket hole of the film at the time of shooting. We have proposed a camera characterized by being equipped with a means for imprinting photographic data that allows for.

When using a camera configured as described above, when shooting, all you have to do is manually or automatically set the shooting data in the shooting data imprinting means and press the camera's shutter button, as shown in Figure 2. Outside the sprocket hole 24 of the film 22 and within the length of the image area 26 of one frame, the focal length 28 of the lens to be used, the brightness of the lens to be used 30, the aperture value 32, the shutter speed 34, and the type of filter to be used 36. You can imprint things such as these when taking pictures.

As described above, the shooting data imprinting means allows shooting data such as aperture value, shutter speed, focal length of the lens used, brightness of the lens used, and type of filter used to be recorded on the outside of the sprocket hole of the film at the time of shooting. If it were possible to imprint, there would be no need to record photographic data in a notebook at the time of photographing to record the photographic situation and then 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.

Problems to be Solved by the Invention However, even if the photographic data is imprinted on the outside of the sprocket hole of the film as described above, when the image of the film is enlarged and printed on photographic paper, the photographic data is transferred to the photographic paper. Do not show. Therefore, even if you look at a photograph printed on photographic paper, you cannot know the photographic data.

Therefore, the present invention makes it possible to write the photographic data on a portion of the photographic paper that does not damage the image when printing a film image onto photographic paper with photographic data imprinted on the outside of the sprocket hole of the film. The aim is to provide the equipment.

Means for Solving the Problems According to the present invention, there is provided a reading device for reading photographic data provided outside the sprocket hole of the film, and an edge portion of photographic paper that receives the output of the reading device. Provided is a device for writing photographic data on photographic paper, which is used in combination with a device for printing a film image onto photographic paper, the device comprising a writing device for writing photographic data. .

If you use a device like the one mentioned above that writes photographic data on photographic paper, a reading device reads the photographic data provided outside the sprocket hole of the film, and a writing device receives the output of the reading device. The photographic data is written on the edge of the photographic paper. Photographic paper is usually bordered by a white border without an image, so even if photographic data is written on the edge of the photographic paper, the impression of the image will not be impaired.

Embodiments Hereinafter, embodiments of an apparatus for writing photographic data on photographic paper according to the present invention will be described with reference to the accompanying drawings.

FIG. 3 is a schematic perspective view of a printing device combined with a device for writing photographic data on photographic paper according to the present invention.

The illustrated printing apparatus has a base 40;
An easel 42 is placed there. This easel 42 is
Movable frames 42C and 42 have fixed frames 42A and 42B, and can be slidably fixed to the fixed frames 42A and 42B as necessary.
D is provided. These frames suppress the edges of the photographic paper and block light.

Additionally, posts 44 extend vertically from the corners of the base 40. A body portion 46 is provided on the post 44 so as to be slidable and fixed as necessary. The body section 46 is provided with a light source, a light scattering screen, a film carrier, an enlarger lens, a filter, and the like. Since the above configuration is conventionally well known, further explanation will be omitted.

According to the present invention, an imaging data reading device 50 is provided, and the writing device 52 is attached to one of the fixed frames of the easel 42 of the device, for example, to the fixed frame 42A.
is provided.

The reading device 50 has a slit 54 into which the outside of the sprocket hole 24 of the developed film 22 is inserted as shown in FIG.

Although the reading device 50 is not shown in detail in the drawings,
A light emitting device and an imaging device are arranged opposite to the slit 54, and a character recognition device is connected to the imaging device. Therefore, the imaging device captures photographic data imprinted on the outside of the sprocket hole 24 of the film 22 inserted into the slit 54, for example, reference number 28.30.
The focal length and brightness of the lens used, the aperture, the shutter speed, and the type of filter used as shown in 32.34.36, for example, 200 (m+yr), F5.6
, fil, 125 (display of molecules is omitted), and images of characters such as L37C are captured. Then, a character recognition device analyzes the captured video and deciphers the characters. Since the imaging device and character recognition device described above are already in practical use, a description of their specific configuration and operation will be omitted. Furthermore, since the photographic data imprinted on the outside of the sprocket hole of the film is not handwritten but has a predetermined lettering pattern, character recognition is not very complicated.

Film photography data decoded by the character recognition device is output to the writing device 52. The writing device 52 can be constituted by a photographic data imprinting device that imprints a character pattern onto photographic paper. Such a photographic data imprinting device can be constructed of, for example, a light emitting diode display element array.

FIG. 4 shows an example of the light emitting diode display element array 70. In particular, assuming that the photographic data is imprinted on the film in the arrangement shown in FIG. 2, the photographic data is printed in the same arrangement. It is for writing on paper.

This light emitting diode display element array 70 is divided, for example, by spacers 70A and 70B in the middle, and consists of 18 light emitting diode display elements 72A so that 18 digit characters can be displayed. It is composed of 2R.

First, the four-digit light emitting diode display elements 72Δ to 72D from the left are composed of eight segments of light emitting diode display elements, and are assigned to display the focal length of the lens used. Therefore, in the illustrated example, a maximum of 999
Can be exposed up to 9 (mm).

The fifth digit from the left, the light emitting diode display element 72E, is composed of a 7-segment light emitting diode display element that is preset to display, for example, rFJ, which indicates the brightness of the lens used, and the following 6 digits from the left. The eye and seventh digit light emitting diode display elements 72F and 72G are taken over by eight segment light emitting diode display elements and are assigned to display the brightness of the lens used. Therefore, in the illustrated example, exposure can be made from Fl, 2 to 2 digits.

7th digit light emitting diode display element 72G and spacer 7
The light emitting diode display element 72H at the 8th digit from the left separated by 0A is preferably constructed of a light emitting diode display element prepared in advance to display an aperture display, for example, rfJ. However, rFJ can be easily displayed with an 8-segment light emitting diode display element, so rFJ
Instead of preparing a display element for displaying J, an 8-segment light emitting diode display element is used which is preset to display "F," to distinguish it from rFJ, as shown in FIG. The light emitting diode display elements 72I and 72J at the 9th and 10th digits from the left, which follow, are composed of 8 segment light emitting diode display elements and are assigned to display the aperture.

Therefore, in the illustrated example, f can be exposed from 1.2 to 2 digits.

10th digit light emitting diode display element? The light emitting diode display elements 72K to 72N from the 11th digit to the 14th digit from the left, which are separated from 2J by the spacer 70B, are 8
It consists of a segment of light emitting diode display elements and is assigned to display the shutter speed. Na right,
Since the shutter speed is most often 1 second or less, the display of the molecule portion is omitted because it is sufficient to understand the information, so in the illustrated example, the display of the molecule portion is omitted. Therefore, in the illustrated example, the light emitting diode display elements 720 to 72.6 are arranged from the 15th digit to the 18th digit from the left and can be exposed for up to 1/9999 seconds. R is composed of an 8-segment light emitting diode display element and is assigned to display the type of film. Since an 8-segment display element is used, both alphabets and numbers can be displayed, and four-digit exposure can be performed by combining the alphabets and numbers indicating the type of filter.

FIG. 5 shows the light emitting diode display element array 70 of FIG.
FIG. 2 is a block diagram of a circuit for setting and driving the . Light emitting diode display element 7 that displays the 5th and 8th digits rFJ and "F," from the left in the light emitting diode display element array
The <16-digit light emitting diode display elements excluding 2E and 72H are connected in parallel to corresponding stages of a 16-stage shift register 74, and the input stage of the shift register 74 is connected to a single-stage register 76. . The distaff 6 is connected to a reading device 52 .

The light emitting diode display element array 70 is connected to a drive circuit 90 which, when the switch 92 is closed, energizes the light emitting diode display element array 70 to the number set by the shift register 74. and imprint the alphabet on photographic paper.

Note that the switch 92 may be closed simultaneously when the light source in the fuselage section 46 is turned on, or may be opened and closed completely independently.

Then, when the photographic paper is developed, the photographic data is developed.

The device described above is used as follows.

First, the reading device 52 detects the edge of a specific frame of the film.
is inserted between the slits 54 of the film to read the photographic data on the edge of the film.

Next, the relevant frame portion of the film is set at an appropriate position in the body section 46. In this state, the position of the fuselage section 46 and its attached lens are adjusted so that an image with the required enlargement ratio is projected onto the photographic paper.

Then, the photographic paper is set on the easel 42. At this time,
Body section 46 exposes the image to photographic paper. At the same time, before or after that, closing the switch 92,
Imprint the photographic data on the edge of the photographic paper.

Then, by developing the photographic paper, a photograph is created with photographic data written on the edges.

Thus, when using the device for writing photographic data on photographic paper according to the present invention as described above, the focal length and brightness of the lens to be used, the aperture, the shutter speed, and the filter to be used are Photographic data such as type can be written on the edge of the photographic paper.

Furthermore, other photographic data such as pan, film type, and sensitivity may also be read and imprinted on photographic paper using only the five photographic data described above.

Further, in the above embodiment, the fixed frame 4 of the easel 42
Although 2A is provided with a writing device, it will be apparent to those skilled in the art that writing devices may be provided on other fixed frames 42B or movable frames 42C or 42D.

Further, the writing device 52 can be configured with, for example, a printer built into a pocket-type electronic computer called a so-called calculator. In this case, each printed body of the printer may be provided in the same manner as the display element array shown in FIG. 4 when the photographic data outside the sprocket hole of the film is as shown in FIG.

Note that the printer preferably prints with oil-based ink. The reason for this is that when water-based ink is used, it is washed off during the washing process after exposure of the photographic paper. Additionally, most of the oil-based inks currently in use are
It is resistant to various processing solutions used in post-exposure processing of photographic paper and will not be washed away.

Furthermore, in the embodiment described above, the photographic data is written on the photographic paper in the arrangement and display method shown in FIG. It will be clear to those skilled in the art that the light emitting diode display element array may be configured so that the captured photographic data can be written alphabetically and numerically on the photographic paper.

Furthermore, it goes without saying that a dot-type display element array may be used instead of the above-mentioned type of light-emitting diode display element array.
