Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a camera device that has a built-in camera device and is equipped with a half mirror for posture alignment on the front side, and particularly relates to a camera device that has a built-in camera device and is equipped with a half mirror for posture alignment. The subject himself is in a half mirror.
The present invention relates to a camera device that can obtain a photograph of a desired framework in focus by lining up and taking a photograph.

[Prior art] Easily take photos of your face for identification purposes such as driver's licenses, ID cards, passports, etc. Shadow! ! tiT1. There are instant photo boxes placed on the streets.

When the subject enters the box, aligns himself while looking at the mirror placed below the lens, and releases the shutter, the desired facial photograph is obtained.

On the other hand, a device in which a camera is attached to the rear of a half mirror (magic mirror) has been proposed in Japanese Utility Model Application Publication No. 49-9229. When the subject aligns himself or herself with the half mirror and releases the shutter, a photograph with the desired framework can be obtained.

[Problems to be solved by the invention] Instant photo booths set up on streets, etc.
Since there is a mirror for alignment at a position far from the camera lens, it is necessary to take your eyes off the mirror when taking pictures, and appropriate precautions are required.

The camera device proposed in Japanese Utility Model Application Publication No. 49-9229 uses a general camera, so it is troublesome to attach the camera to a half mirror, and focusing is required. Even if an autofocus camera were used, it would be impossible to use because the focus is on the half mirror in front of the camera lens.

Also, since the area around the camera is open, it can be used as a half mirror.
Reflected light from the back side and external light are reflected in the image.

As mentioned above, conventional camera devices of this type are inconvenient to handle, and high-quality photographs cannot be easily obtained.

In light of the above-mentioned circumstances, we conducted research from a psychological perspective and found that when people look at the reflected image in a mirror, they measure and position it with their eyes so that it is an appropriate size, and then look at the reflected image. Ta. That is, it has been found that the distance between a mirror and a person is usually determined by itself, and that there exists a certain distance at which, for example, a reflected image of the entire face is reflected.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a camera device that can take a high-quality, well-focused photograph by simply aligning the subject in a fixed position and taking the photograph.

[Means for Solving the Problems 1] In order to achieve the above object, the camera device according to the present invention has the following features:
A camera unit capable of photographing an image passing through the half mirror is installed in a cabinet equipped with a half mirror on the front and a dark room at the rear, and the distance between the camera lens of the camera unit and the imaging plane behind the cabinet is set as follows. It is characterized in that the positional relationship is set and fixed so that the front subject photographed within the half mirror is in focus.

[Function] At a fixed position in front of the half-mirror, the subject himself determines the framework of his own image reflected in the half-mirror. Therefore, by releasing the shutter of the camera section, the half mirror can be
The image of the object transmitted through the camera lens passes through the camera lens and forms an image on the imaging surface of a film or the like.

Since the distance between the camera lens and the image plane is set and fixed so that the subject at a certain position in front of the half mirror is in focus, the image projected onto the image plane is optimal.

The inside of the cabinet is in a dark room, and the camera unit is placed in an environment free from unnecessary external light and diffused light, allowing for high-quality photographs.

The half mirror and camera unit are housed in a cabinet, making it compact and easy to transport and install.

[Embodiment of the Invention] A preferred embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a partially cutaway perspective view of a camera device according to the present invention, Fig. 2 is a partially cutaway side view of the same, Fig. 3 is a partially cutaway perspective view of the camera section, and Fig. 4 is an explanation of the positional relationship between the lens and the imaging plane. It is a diagram.

In the figure, 1 is a cabinet. This cabinet) 1 has a mirror window 2 on the front, and the rear part is opened to form a camera mounting part 3. The illustrated embodiment is the above-mentioned cabinet).
It consists of two parts, a front part and a rear part, but this form is only adopted because of the design of the cabinet, which is molded from plastic resin or the like. therefore.

The cabinet l may be configured as a single unit, or
The handle part 4 may be composed of three or more parts, and is formed by providing a substantially U-shaped space on the upper surface of the cabinet (1).

Reference numeral 5 denotes a half mirror that is closely attached to the inner edge of the mirror window 2 of the cabinet.This half mirror 5 reflects the image in front of the mirror and transmits a part of it to the rear, but it is transparent from the rear. Light is not allowed. Therefore, when viewed from the front of the half mirror 5, only the reflected image can be seen, but the rear image of the mirror 5 cannot be seen through. On the other hand, the image in front of the mirror can be seen through from the back side of the mirror.

A weight member 7 is provided at the bottom of the leg member 6, which is a leg member that supports the axis of the cabinet 1 so as to be able to tilt the cabinet 1 in the front-rear direction.This stabilizes the support of the cabinet 6 by the leg members 6. can be converted into

Reference numeral 8 denotes a strobe flash embedded in the upper front surface of the cabinet 1.

1O is a camera unit housed inside the cabinet 1. As shown in FIG. 3, this camera section 10 includes a lens section 11. Lens barrel 12. It consists of a photographic cartridge 13. The lens unit 11 here has a two-lens configuration and includes a pair of camera lenses 14 and 14. In other words, the same subject can be printed side by side on a single photographic print with a single shutter operation. Therefore, a partition plate 15 is provided at the rear of the lens section 11 so that the transmitted light from the pair of camera lenses 14 and 14 does not interfere with each other.

A shutter mechanism and an aperture mechanism are built into the head 1B of the lens section. The shutter mechanism can be remotely operated by a release 17 pulled out from the cabinet l. Also, the aperture mechanism is a wire pulled out from the bottom of the lens section and wound around the wheel 18! It can be adjusted by operating 9.

The mirror 11iq12 has mounting pieces 20, 20...
・is being planted. Further, a flange portion 21 is provided at the rear end of the mirror I412, so that the photographic cartridge 13 can be attached and held and the cabinet I can be fixed to the camera mounting portion 3. An aperture dial 23 is rotatably supported on the flange 21 via a metal fitting 22, and the wire 19 is wound around a wheel 24 fixed coaxially with the dial 23. Therefore, by rotating the dial 23 with a fingertip, the aperture operation described above can be performed.

The above-mentioned camera unit 10 is attached to the cabinet screw 1 by screwing the screw 28.2El into the cabinet 1 through the mounting holes 25, 25... bored in the corners of the flange 21.
Further, the flange 21 is provided with a cartridge mounting member 27.27, which allows the photographic cartridge 13 to be attached and removed.

The photo cartridge 13 stores photosensitive material such as photographic film, and when it is alone, the photosensitive material is protected from light by a light-shielding screen, but when it is loaded into the camera unit IO and in the shooting state, the light-shielding screen 28 is removed. It looks like this.

In the camera section having the above configuration, the positional relationship between the camera lens 14 and the photographic film, which is a photosensitive material, will be explained below with reference to FIG. 4.

The camera unit 10 built into the cabinet l.

A camera lens 14 is disposed opposite to the rear of the half mirror 5, and a photographic film (imaging surface) 30 is fixed behind the lens 14 at a distance f. This distance #f is determined by the distance to the subject S based on the focal length of the camera lens 14. Therefore, in order to fix the distance ft-, the setting is made so that when the subject person is located a distance away from the camera lens 14, the subject person will be reflected in the half mirror 5 at an appropriate size. From a psychological point of view, it is expected that the subject person will look at the self-image in the half mirror 5 and visually measure the distance, but in practical terms the depth of field of the lens allows for a slight deviation in focus. There is no problem; of course, you can use a scale to measure the distance between the camera device and the subject, or mark the positions of both on the floor.
It is also a good idea to set the length of to the shooting distance.

The case where a desired photograph is taken with the above-mentioned camera device will be explained below, and its operation will be clarified.

First, the photographic cartridge 13 containing unexposed photographic film is attached and fixed to the back of the camera unit 10 using the mounting members 27, 27 provided on the flange 21, and the light-shielding screen 28 is removed. Dial 2 according to brightness
3 to set the appropriate aperture. Once you are ready to take a picture, place the camera device in an appropriate location, and use a half-mirror so that the subject can obtain the desired framework at a predetermined distance. Adjust the inclination of the cabinet l with respect to the leg members 6 while looking at the image reflected in 5. When the shutter is released by operating the release 17, the subject image passes through the half mirror 5 and the lens 14, and is projected onto the photographic film 30 on the imaging plane, and the film 30 is exposed.

If the photographic film is instant photographic film,
When the photographic cartridge 13 is removed and the film is taken out, the desired photographic print can be obtained immediately. Since the camera section here has a two-lens configuration, the obtained photograph has the same image on both sides, and is suitable for original and sub-photographs of various certificates.

When the brightness of the subject is dark, it is recommended to use the strobe flash 8 to emit light.Also, when carrying the camera, it is possible to easily carry the camera by holding the handle 4.

In the above embodiment, the description was made with the half mirror 5 in mind to capture the subject, but it is also preferable to set a large mirror and focal length that will allow the entire subject to be captured, like a full-length mirror. Designs can be easily made.

Further, although the camera unit 10 has been illustrated and described, it is not prohibited to mount an existing camera device inside the cabinet.

[Effects of the Invention] As is clear from the above, according to the present invention, the camera lens and the photographic film, which is the imaging surface, are arranged so that the camera lens and the photographic film, which is the imaging surface, are brought into focus at the subject position that is separated by a preset photographing distance. Since the distance between the camera and the camera is fixed, you can take a good, well-focused photo by standing in a fixed position in front of the camera while checking the reflected image of the half mirror. Moreover, since the half mirror allows the subject person to confirm the framework himself/herself, it is possible to obtain a photograph of the desired framework without causing any positional shift. As mentioned above, since focusing is no longer necessary, the structure of the camera section can be simplified and the failure rate can be reduced. In addition, since the half mirror and camera section can be housed together in the cabinet, handling is simplified and transportability is improved, which provides excellent effects.
