Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a photographing apparatus such as a still camera.

[0002]

2. Description of the Related Art Conventionally, when a photographer is a subject, the following measures have been used to determine the field of view, focal length, and exposure value of a camera. That is, first, the photographer places the camera on a tripod, a table, or the like, and determines the outline of the photographing composition by looking through the viewfinder. Or
Determine the shooting composition based on your intuition without looking through the viewfinder. Next, the photographer becomes a subject and releases the shutter of the camera by remote control or button operation, etc., and performs photographing. A digital camera such as a charge-coupled device (CCD) also requires a separate monitor.

Further, recently, a self-portrait is photographed by a disposable camera having a fixed focal length (for example, 70 cm), but the situation is the same as described above.

[0004]

In the prior art, after a photographer determines the outline of a photographing composition by looking through a viewfinder from the rear side of the camera, the photographer moves to the front side of the camera and operates a remote control or button operation. , The camera shutter was released, and the camera was shooting. Therefore, the conventional technique has the drawbacks that the number of steps for photographing is complicated and that the field of view of the camera tends to be inaccurate.

Accordingly, the present invention is to improve the disadvantages of the above-mentioned prior art, to simplify the number of photographing steps, and to provide a view confirming structure of a photographing apparatus such as a still camera in which the photographer is a subject, which has an accurate view range. It is intended to provide.

[0006]

The present invention employs the following means to solve the above-mentioned problems. (1) A field-of-view confirming structure of a photographing apparatus in which a subject is provided with a light reflector on the front of the photographing apparatus for confirming the field of view of the photographing apparatus. (2) The visual field confirmation structure of the imaging device according to (1), wherein a marking for displaying an imaging region is provided on the reflector. (3) The field-of-view confirmation structure of the imaging device according to (1), wherein a concave lens is added to the front surface of the reflector. (4) A light reflection plate for confirming the field of view of the photographing device is rotated by 90 degrees at the front end of one side of the viewfinder so that the light reflecting plate is provided at the front of the viewfinder. A field-of-view confirmation structure for a photographing device that is attached as possible. (5) A field-of-view confirming structure of a photographing apparatus in which a half mirror for allowing a subject to confirm the field of view of the photographing apparatus is detachably provided in front of the photographing lens.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Three embodiments of the present invention will be described with reference to FIGS.

First, a first embodiment of the present invention will be described with reference to FIG.

In FIG. 1A, a photographing lens 2 is provided at the center, a finder 3 is provided at the center of the upper part, and a flash unit 4 is provided at the upper right side, facing the front of the camera 1. A shutter button 5 is provided on the left side of the upper surface of the camera 1.

On the left side of the lower part of the front surface of the camera 1, a light reflecting plate 6 made of a glass mirror or aluminum foil is provided. The reflecting plate 6 may be provided on the entire front surface of the camera 1 (excluding the lens 2, the finder 3, and the flash device 4).

As shown in FIG. 1B, the reflecting plate 6 has
The marking 7 is provided so that the photographing area can be visually recognized in accordance with the photographing distance or the focal length. Further, as shown in FIG. 1C, a concave lens 8 is added to the front surface of the reflection plate 6 to facilitate visual recognition.

Further, when the reflecting plate 6 itself is formed in a concave shape, the area occupied by the reflecting plate 6 can be reduced.

At a position within a predetermined range from the front surface of the camera 1 described above, the subject 9, ie, the photographer 9, confirms himself / herself reflected on the reflection plate 6, and operates the camera 1 by remote control or button operation. When the shutter button 5 is pressed, shooting is performed.

Next, a second embodiment of the present invention will be described with reference to FIG.

In FIG. 2A, a rectangular parallelepiped finder 11 is provided at the center of the upper part of the front surface of the camera 1 so as to be able to enter and exit the front surface of the camera 1. A rectangular reflector 12 is attached to the right front end of the finder 11 by a vertical hinge 13 so that the reflector 12 can be rotated 90 degrees, and a knob 14 is fixed to a portion of the reflector 12 near the hinge 13. The hatched side of the reflector 12 is the back surface of the reflector 12.

In the case of ordinary photographing, the reflector 12 is folded and positioned parallel to the direction in which the finder 11 enters and exits. The finder 11 and the reflector 12 are housed in the camera 1.

When the photographer takes an image of a subject, the user pulls the knob 14 to pull out the finder 11 from the camera 1. The knob 14 rotates the reflecting plate 12 counterclockwise by 90 degrees to hold the finder 11 at a position parallel to the front of the camera 1. cause.

The design of the structure of the reflector 12 shown in FIG. 2A can be changed as follows. That is,
As shown in FIG. 2B, the hinge 13 is arranged horizontally and in parallel with the front of the camera 1, and the knob 14 is fixed to the left front end of the reflector 12. The operation of the reflection plate 12 is as follows.
This is the same as in the case of FIG.

Next, a third embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 3A, a half mirror 21 is detachably provided on the front surface of the taking lens of the camera 1.
As shown in FIG. 3B, the half mirror 21 has a reflection surface 22 on the front surface and a transmission surface 23 on the rear surface.

In the case of normal photographing, the half mirror 21 is detached from the camera 1.

In the case of photographing in which the photographer is a subject, the half mirror 21 is mounted on the photographing lens of the camera 1. Although the amount of light taken by the taking lens decreases, photography is possible.

[0023]

As is apparent from the above description, the present invention has the following advantages. (1) It is possible to obtain a field-of-view confirmation structure of a photographing apparatus in which a photographer is a subject, in which the number of photographing steps is simple and the field of view is accurate. (2) It can be widely used in still cameras, video cameras, ID photographing devices, and the like, which is convenient.
