Abstract

PURPOSE:To prevent a decrease in the contrast of the image projected on a half mirror by subjecting the rear face of a mirror member except the enclosing range of a camera mounting part to light shielding and forming a mirror device in such a manner that the image transmitted through the half mirror part can be photographed by a camera mounted on the camera mounting part. CONSTITUTION:Since the axial center of the camera mounting part 3 is orthogonal with the plane of the mirror member 1, the optical axis of the camera (a) maintains the orthogonality with the plane of the member 1 when the camera (a) is fitted into the camera mounting part 3 provided to the rear face of the member 1. The shutter of the camera (a) is released where a subject person projects his own figure on the surface of the mirror part 1 member and determines his position. Then, the subject image is transmitted through a semitransparent part 6 and is formed on a camera film. The photograph of a framework projected on the member 1 is thus surely obtd. The part of the member 1 except the camera mounting part 3 is subjected to the light shielding to prevent the fall of external light to the rear face of the member 1. The decrease in the contrast of the subjected image projected on the mirror member is thereby obviated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mirror device for photographing that allows the subject to align himself or herself so that he or she can define a desired photographic framework and take the photograph. In particular, the present invention relates to a mirror device in which at least a portion of a mirror member that reflects a person as a subject is semi-transparent so that a camera can be attached from behind the mirror member to photograph the subject.

[Prior Art] As a device for photographing a photographic subject himself/herself to take a facial photograph required for various certificates, etc., there is a photographic device proposed in Japanese Utility Model Application Publication No. 49-9229. This conventional photographic device has a structure in which a camera is screwed into an open space behind a half mirror (magic mirror) via a frame metal fitting. When taking photos with this device, the subject person is reflected on the surface of the half mirror.
By aligning the image while looking at it, and then releasing the shutter of the camera, you can take a photo of the desired framework.

[Problems to be Solved by the Invention] Since the camera used in the above-mentioned conventional photographic equipment is placed in an open space behind the half mirror and exposed to external light, there is no need for reflected and diffused light on the back of the half mirror. This reflects light and impairs the saturation of the photograph taken, and furthermore, the contrast of the reflected image on the surface of the half mirror is reduced by the light rays that the half mirror receives from the back. Further, although the camera is screwed to the frame metal fitting behind the half mirror, it is not always possible to obtain a photograph with the optical axis of the camera lens aligned with the framework of the subject reflected on the half mirror.

However, the uninvented purpose of the half mirror is to make it possible to easily attach a camera to the back of the nof mirror used for face-to-face alignment, and to ensure that the camera can take pictures of the subject using the framework reflected in the half mirror. In addition to being able to set a constant camera optical axis at all times, it also prevents unnecessary light from irradiating the back of the half mirror, reducing photo saturation due to unnecessary light reflection and reducing the contrast of the half mirror's projected image. An object of the present invention is to provide a photographic mirror device that can prevent the above-mentioned problems.

[Means for Solving the Problems] In order to achieve the above object, a mirror device according to the present invention includes a mirror member having a semi-transparent part at least in the center, and a rear surface of the semi-transparent part. and a cylindrical camera mounting part having an axis perpendicular to the mirror member, which blocks light from the rear surface of the mirror member other than the area surrounding the camera mounting part, and transmits light through part of the 7--Fumira. The camera is characterized in that the captured image can be photographed by a camera mounted on the camera mounting section.

[Function] When a camera is fitted into the camera mounting part provided on the back surface of the mirror member, the optical axis of the camera is orthogonal to the mirror member surface because the axis of the camera mounting part is orthogonal to the mirror member surface. When the subject reflects his or her own image on the surface of the mirror member and positions it, the shutter of the camera is released, and the image of the subject passes through the semi-transparent part and forms an image on the camera film. Since the optical axis of the camera is always perpendicular to the mirror member, a photograph of the claim work reflected on the mirror member can be reliably obtained.

The mirror part other than the part where the camera is mounted is shielded from light, and as external light does not hit the back of the mirror member, the contrast of the reflected image will not be reduced, and unnecessary light reflection on the camera can be prevented. .

Therefore, the reflected image on the surface of #11 member is easy to see.
Also, you can take photos with good color saturation.

Other objects and features of the present invention will become clear from the following description of embodiments based on the accompanying drawings.

[Embodiment] Figure 1 is a partially cutaway perspective view showing an embodiment of the present invention.
FIG. 2 is a side sectional view.

In the figure, 1 is a mirror member. The mirror member 1 in this embodiment can be made into a semi-transparent half mirror on its entire surface.
A semi-transparent reflective film is attached to the back side (right side in the figure) of the camera, which reflects the image from the front side (left side in the figure) while allowing some of the image light to pass through to the back side.

Reference numeral 2 denotes a camera device attached to the center of the back surface of the mirror member 1. The camera mounting portion 2 has a cylindrical shape with an inner diameter that allows the lens barrel of a camera a applied to this device to be fitted therein, and its axis is perpendicular to the mirror member 1. A camera mirror Ii is installed in the camera mounting part 2! A camera mounting member 3 is provided to stably hold the camera. The camera attachment member 3 here has a structure in which the camera attachment part 2 is lined with an elastic material such as rubber or synthetic resin, and the camera lens mirror PB fitted into the camera attachment part 2 can be easily separated by frictional force. I try not to.

Reference numeral 4 denotes a light shielding member extending from the front end of the camera mounting portion 2 in the shape of a brim. This light shielding member 4 has approximately the same size as the mirror member l, and is in contact with the back surface of the mirror member l. The light-shielding member 4 may be joined to the mirror member 1 using an adhesive, or the periphery of the light-shielding member 4 may be joined to a substantially U-shaped edge member 5 attached to the periphery of the mirror member 1 as shown in the figure. Of course, the light shielding member 4 may be attached to the mirror member l by using a combination of fixing the peripheral edge with the edge member 5 and bonding with the former adhesive.

Further, the edge member 5 not only has the function of simply holding the light shielding member 4, but also has the function of protecting the peripheral edge of the mirror member l.

When using the mirror device configured as described above, preparation for photographing is completed by simply fitting the lens barrel of the camera a into the camera mounting portion 2. After the person to be photographed is positioned by reflecting his/her figure on the mirror member 1, the shutter of the camera is released using a means such as a self-timer or release. As a result, an image of the object transmitted through the mirror member l is formed on the film loaded in the camera a. As a result, it is possible to obtain a photograph of the framework that the subject has confirmed using the mirror member l. Furthermore, when the camera lens b is fitted into the camera mounting part 2, the image is received only by the transparent image of the subject from the semi-transparent part 6 of the mirror member facing the camera lens b, so that the camera mounting part 2 is effectively Demonstrates the action of a hood. Therefore, photographs obtained with the above camera have richly saturated colors without unnecessary light.

Further, since the light shielding member 4 is attached to the back surface of the mirror member 1 other than the light-transmitting portion 6, external light does not hit the back surface of the mirror member 1, so that the contrast of the reflected image on the front surface does not deteriorate.

As is clear from the above explanation, it is only necessary to make the mirror member l transparent only in the surrounding area (transparent part 6) of the camera mounting part 2. In other words, only the transparent part 6 should be made into a nose mirror, and the other parts should be made transparent. If the part is made into a total reflection mirror structure, the light shielding member 4 can be changed from the above embodiment.
can be omitted.

As explained above, according to the above embodiment, since the axis of the cylindrical camera mounting part 2 is fixed perpendicularly to the mirror member, the camera a can be easily attached to the camera mounting part 2. Even if a person is photographed, the tip axis will point the subject at right angles to the mirror member, so
The subject can be easily positioned by simply checking the image reflected on the mirror member without causing the framework to shift.

In the above-mentioned embodiment, if it is difficult to divide one mirror member into a total reflection part and a semi-transmission part, the structure described below may be maintained.

FIG. 3 shows another embodiment, and the modification from the previous embodiment is that the light shielding member which was extended in the shape of a brim to the camera mounting portion l is omitted. The camera mounting part 1 is directly joined to the back surface of the mirror member 1, and a light-shielding paint or a light-shielding film 7 is attached to the back surface of the mirror member other than the surrounding area (semi-transparent part) of the camera mounting part 1. With this configuration as well, the same effects as in the embodiment described above can be obtained, but the edge member 5 described above can be omitted here.

Further, in the embodiment shown in FIG. 3, a leg member 8 can be attached to the lower edge of the mirror member l. This leg member 8 allows the entire installation including the mirror member and camera to be stabilized on a predetermined flat surface. Of course, without relying on the chest member 8, the entire camera may be supported on a commercially available tripod by screwing a pan head or the like into a mounting screw hole provided on the bottom of a normal camera.

The embodiment shown in FIG. 4 can be applied to various types of cameras with different sizes and shapes of camera lens barrels.
Attachment) 10 is used. This attachment 10 has an engaging part 11 that can be connected to the camera mounting part 3.
and a holding part 12 that receives and holds the lens mirror @b of the camera a. The connection structure between the attachment 10 and the camera mounting portion 2 here is a screw-in structure consisting of a male thread and a solid thread on the circumferential surfaces in contact with each other, but it is of course not limited to this.

Since the distance from the mirror member 1 to the camera lens becomes longer by using the attachment 1O, it is preferable to expand the diameter of the front half of the camera mounting portion 3 to prevent vignetting of the camera view angle.

In the above embodiment, the camera mounting section 3 may have a structure in which a camera body can be mounted thereon.

[Effect of the invention 1 As described above, according to the present invention, the camera mounting portion is provided on the back side of the semi-transparent portion provided at least in the center of the mirror member,
The image of the subject in front of the mirror member that passes through the light-transmitting part can be photographed using a camera attached to the camera mounting section, so the user can easily capture the desired image by simply positioning the subject while reflecting their figure on the mirror member and releasing the shutter. Framework photos easily,
You can definitely take pictures.

In addition, the back side of the mirror member is shielded from light except for the semi-transparent part surrounded by the camera mounting area, so even if outside light hits the back side of the mirror member, the contrast of the image reflected on the front surface will not deteriorate and it will be easy to see. The above positioning is possible. Moreover, since no unnecessary light enters the camera lens, the chroma of the photographed photograph is improved.
