Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data imprinting device for a camera that imprints data onto the film of a camera.

[Summary of the invention]

The present invention provides a display device for displaying imprint data in a data imprinting device for a camera, in which the shape of the data is deformed, and the film is placed at an angle and at a distance from the display device, and the film is placed in a curved manner. By imprinting normal data on the film, the quality of imprinting on the film is improved, and components such as lenses are eliminated, making the device smaller and cheaper.

[Conventional technology]

Data imprinting devices for cameras using a display have already become common, and their structure is such that the white data on the display and the film are always arranged in parallel. The light from the light source that illuminates the white data on the display is imprinted onto the film in a manner similar to the white data.

FIG. 2 is a conceptual diagram of a conventional camera data imprinting device. That is, 21 is a light source for imprinting, 22 is a display device such as a liquid crystal display element that displays imprint data in a white outline, and 2
5 is the imprint data, 24 is the film stored in the camera, 25 is the luminous flux emitted from the light source 21, and 26 is the data imprinted on the film by the luminous flux 25.

Since the luminous flux 25 is almost straight light, the imprint data 23
The imprinted data 26 has substantially the same shape, and the data formed by the display 22 is correctly imprinted onto the film 24.

[The problem that the idea attempts to solve]

However, in the above-mentioned conventional technology, when the film 24 is arranged in a curved manner or at an angle and at a distance from the display 22, the imprint data 23 and the The resulting data 25 does not have a similar shape, and the quality of imprinting is significantly degraded.

Furthermore, if a lens or the like is placed between the film 24 and the display 23 in an attempt to solve the above problem, the cost of the product will increase and the thickness of the product cannot be reduced (and new problems will arise).

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and its purpose is to improve the quality of display data projected onto film in a data imprinting device for a camera;
The purpose is to reduce the size and cost of the device.

[Means for Solving the Problems] The camera data imprinting device of the present invention deforms the data on the display in advance so that the film to be imprinted is placed at a distance and tilted relative to the display. It is characterized by imprinting normal data even if it is arranged or arranged in a curved manner.

〔Example〕

FIG. 1(α) is a perspective view of an embodiment of the present invention.

In the figure, 11 is a light source such as a lamp, 12 is a display device such as a liquid crystal display element, 15 is white and deformed data (hereinafter referred to as imprint data) 14 is stored in a camera, and 14 is a display device and an angle. A film 15 (hereinafter referred to as film) placed at a distance from the lamp 11 is a light beam emitted from the lamp 11, and 16 is data (hereinafter a copy) imprinted as a normal shape on the film 14 by the light beam 15. In other words, the luminous flux 15 emitted from the light source 11 projects the display 12,
The white and deformed imprint data 13 is dropped onto the film 14, where it is imprinted with normal shape data 1.
It becomes 6. In this case, the white imprint data 13 on the display 12 gradually becomes thicker from the left data as shown in the figure, and the light beam 15 passing through the thin white data has an angle. When it gradually diffuses and reaches the film 14, it has the same size as the light beam 15 that passed through the thick white data, and is imprinted as data 16 on the film 14 as normal data.

FIG. 1Cb) shows a plan view of FIG. 1(α).

In the figure, the luminous flux 15 emitted from the light source 11 is
2 is projected, and white data 15 that gradually becomes thicker from the left is deposited onto the film 14, where it becomes imprinted data 16 of the same size and normal shape.

FIG. 1(C) is a perspective view of an embodiment of the present invention.

In the figure, 1 is a light source such as a lamp, 2 is a display device such as a liquid crystal display element, 3 is a blank and deformed data (hereinafter referred to as "imprint data"), and 4 is a film (hereinafter referred to as "imprinted data") arranged in a curved manner in a camera. (abbreviated as film) 5 is the light source 1
The luminous flux 6 generated by the above is data (hereinafter abbreviated as "imprinted data") imprinted on the film 2 as a normal shape by the luminous flux 5.

That is, the luminous flux 5 emitted from the light source 1 projects the display 2, and casts white and deformed imprint data 6.
The film reaches the film 4 and becomes data 6 with a normal shape. In this case, as shown in the figure, the white imprint data 5 on the display 2 gradually becomes thinner toward the left and right from the center data, and the light flux 5 passing through the white data on the left and right Because it has an angle, it gradually diffuses, and when it reaches the film 4, it becomes the same size as the light beam 15 that passed through the thick white data in the center, and is imprinted on the film 4 as normal data. It is imprinted as data 6.

〔Effect of the invention〕

According to the present invention described above, by deforming the data of the display device that displays desired data in advance, the film can be arranged at a distance and at an angle with respect to the display device, and the film can be arranged in a curved manner. Correct data can be imprinted even on film that has been exposed, and the imprint quality of the device is significantly improved. In addition, since optical members such as lenses are not used, the device can be made smaller and less expensive. The effect is extremely large.
