Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, the mirror surfaces of two surface mirrors are opposed to each other in the upright posture so as to be plane orthogonal to each other, and the target image normalization is obtained by obtaining a right-left image of the target image through double reflection occurring between both surface mirrors. More particularly, the present invention relates to an open / close-type orthogonal mirror that can be opened / closed by changing the mirror crossing angle of the left and right surface mirrors.
[0002]
[Prior art]
In a conventional orthogonal mirror in which two surface mirrors are arranged orthogonally on the left and right in a plane to normalize the target image, the arrangement of the two surface mirrors is fixed (for example, Japanese Patent Application No. Hei 7- 217034: “Viewing angle determination device, observation visual field positioning observation device, imaging visual field positioning imaging device, and target image normalization orthogonal mirror”). This is because the technology related to the conventional object image normalization orthogonal mirror is limited to the category of professional business technology such as a measurement device and an observation device.
[0003]
Since this technology is realized as a three-dimensional shape with a mirror fixed in a plane orthogonal shape, its large spatial volume is inconvenient for transportation, storage and storage when viewed from the consumer base and general business use conditions. It was in form.
Therefore, the present applicant has previously filed an application regarding a proposal of a technique for realizing a general folding orthogonal mirror (see Japanese Patent Application No. 9-209536: “Folding orthogonal mirror”).
[0004]
[Problems to be solved by the invention]
However, in the folding type orthogonal mirror according to the above-mentioned prior application, the operation of opening from the folded state to the orthogonal state and the operation of closing from the orthogonal state to the folded state are troublesome, and the general user is in a daily environment. It is not very convenient to use. In addition, in an orthogonal mirror, it is generally necessary not only to open both surface mirrors and accurately reproduce both mirror surfaces in an orthogonal state, but also to maintain the orthogonal state. It is difficult to obtain better reproducibility and retention of the orthogonal state.
[0005]
Therefore, the present invention can easily obtain a face image or a whole body image having the right and left relationship seen by the opposite party, not in a horizontally reversed image obtained by a conventional mirror, even in a general life. Therefore, an object of the present invention is to solve the problem in the form for opening and closing the target image normalization orthogonal mirror.
In order to be able to open and close the target image normalization orthogonal mirror, the left and right surface mirrors, which have been conventionally fixed, must be separated and reconnected. An object of the present invention is to provide an openable / closable orthogonal mirror that solves the following problems (1) to (4), with the objective of using the separated left and right surface mirrors as a target image normalizing orthogonal mirror. The purpose is to do.
(1) Issues for holding the separated left and right surface mirrors so that the mirror surfaces are closely orthogonal to each other (2) To reconnect the separated left and right surface mirrors so that they can be opened and closed with both mirror surfaces facing each other (3) Problem to stably reproduce the mirror orthogonal state in the open state of both surface mirrors (4) Problem to reproduce the precise mirror orthogonal state by adjusting the crossing angle of both mirror surfaces ]
[Means for Solving the Problems]
In order to achieve the above object, an open / close type orthogonal mirror according to claim 1 of the present invention includes two surface mirrors each having a surface as a light reflecting surface, and two surfaces each holding one surface mirror. Mirror holder, hinge attached to the front of both surface mirror holders so that both surface mirrors can be opened and closed, and one surface mirror holder to automatically hold the open state Provided on the inner surface of one surface mirror holder so that the magnets and magnetic body provided on the inner surface of the other surface mirror and the magnet or magnetic body provided on the inner surface of the other surface mirror holder can be accurately orthogonalized. It consists of a screw that adjusts the distance from the inner surface of the other surface mirror holder attracted by magnetic force by the advancement and retraction of the screw, and each inner surface is inclined so that the inner surfaces of both surface mirror holders face each other The inner edge of one surface mirror is in close contact with the surface of the other surface mirror As the inner end of each of the front surface mirror is characterized in that protrudes from the inner surface of the front surface mirror holder, the technical problem (1) can be solved to (4) simultaneously.
[0007]
In this orthogonal mirror, the surface mirror holder that holds the surface mirror is movably connected to each other by a connector so that it can be changed between a closed state and an open state. Not only can the operation of changing the interval be easily performed, but also the mirror orthogonal state can be stably reproduced and maintained.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail by embodiments. FIG. 1 is a conceptual diagram illustrating the operating principle of an open / close type orthogonal mirror according to the present invention.
The image of our face that we see in a normal mirror is an inverted image. Structured lights incident from the target image are specularly reflected by the mirror surface, so the left-right relationship of the reflected image is the so-called left-right reversal of the image seen when the target image is facing away from the mirror side. It becomes a mirror image.
[0009]
On the other hand, the orthogonal mirror according to the present invention is a mirror in which two planar surface mirrors 11 and 12 are arranged in a posture (inner angle of π / 2) in which the mirror surfaces are orthogonal to each other as shown in FIG. 1A.
Due to the arrangement of the mirror-surface orthogonal mirrors, as shown in FIG. 1B, for example, light incident on the right mirror surface 11 at an incident angle θ is reflected at a reflection angle θ and enters the left mirror surface 12. Since the incident angle is {(π / 2) −θ}, the reflection angle by the left mirror surface 12 is also {(π / 2) −θ}, which has a parallel vector and a reverse vector with the light incident on the right mirror surface 11. Light is emitted.
That is, the rectilinear incident light incident on the right mirror surface 11 at π / 4 is reflected as rectilinear reflected light from the left mirror surface position that is exactly symmetrical with respect to both mirror surface boundary lines 15.
[0010]
In this way, the left and right of the structured light from the target image 13 are inverted through double reflection, so that the target image 14 as if facing away from the other side of the mirror is obtained. In other words, in the case of a face image, it is possible to see one's face image seen by another person with this orthogonal mirror. Needless to say, the roles of the left and right mirror surfaces described above are interchangeable. However, the surface mirrors 11 and 12 need to be surface mirrors whose surfaces are light reflecting surfaces. When using a rear-view mirror with the rear surface mirrored by metal vapor deposition or plating, the incident light is double refracted when passing through a transparent body such as glass on the front surface, which significantly reduces the quality of the reflected image. Therefore, it cannot be used.
[0011]
FIG. 2 shows a conceptual configuration of an orthogonal mirror in which the general utility is given to this orthogonal mirror, that is, the opening and closing operation of the mirror surface is easy and the reproducibility and retention of the orthogonal state of the mirror surface is improved. Shown in In FIG. 2, a right surface mirror r whose surface is a mirror surface 21 is held by a surface mirror holder 23, and a left surface mirror l whose surface is a mirror surface 22 is also held by a surface mirror holder 24. Both surface mirror holders 23 and 24 are connected by a hinge 25 so as to be opened and closed. Further, the inner side surfaces 26 of both surface mirror holders 23 and 24 are inclined so as to obliquely intersect the mirror surfaces 21 and 22 so that the mirror surfaces 21 and 22 of the surface mirrors r and l are in an open state in close contact with each other at a right angle. It is a surface.
[0012]
Next, see FIG. 3 (partial sectional view (c) in a closed state, partial sectional view (d) in an open state) showing a schematic view of a specific openable orthogonal mirror according to the embodiment as viewed from above. To explain. However, the relative dimensional ratio of each part, the mounting position of each part, and the inclination angle of the inner surface of the left and right surface mirror holders are examples shown for convenience of explanation, and can be changed as appropriate. Of course.
[0013]
In FIG. 3, the right surface mirror r whose surface is the mirror surface 21 is held inside the surface mirror holder 23, and similarly, the left surface mirror l whose surface is the mirror surface 22 is held inside the surface mirror holder 24. Yes. Both surface mirrors r and l are positioned at portions closer to the inside (mirror surface side) of the surface mirror holders 23 and 24, respectively.
The inner end portions of the surface mirrors r and l slightly protrude from the inner surfaces 26r and 26l of the surface mirror holders 23 and 24, respectively. In this embodiment, the length of the inner end protruding portion of the right surface mirror r is set longer than the length of the inner end protruding portion of the left surface mirror l by the thickness dimension of the surface mirror l. For this reason, in the orthogonal state of the mirror surfaces 21 and 22, the inner end surface of the left surface mirror l can be in close contact with the mirror surface 21 of the inner end protruding portion of the right surface mirror r. This closeness is a necessary condition for the stable establishment of the orthogonal mirror. If the inner end edges of the surface mirrors r and l are in contact with each other, the contact between the edges is very unstable, so there is no overall gap even when the surface mirrors r and l are in an orthogonal state. The orthogonal state cannot be obtained.
[0014]
Both the surface mirror holders 23 and 24 are connected to each other by a hinge (hinge) 25 as a connecting tool attached to an inner end portion inside thereof. As described above, the hinge 25 is accurately positioned at the inner end portions inside the surface mirror holders 23 and 24 so that the inner end portions of the surface mirrors r and l come into close contact with each other. Has been. With this hinge 25, the surface mirror holders 23 and 24 are connected to each other with the hinge 25 as a fulcrum in a closed state (C in FIG. 3) facing each other and an open state (D in FIG. 3) close to each other at right angles. Can be opened and closed (rotated). Of course, the hinge 25 may be attached at a position and posture other than those shown in FIG. 3 as long as close contact between the inner end protruding portions of the surface mirrors r and l is realized.
[0015]
Inner side surfaces 26r and 26l of both surface mirror holders 23 and 24 are inclined surfaces that obliquely intersect mirror surfaces 21 and 22, respectively. The inclination angles of the inclined surfaces 26r and 26l are set to angles at which the two surface mirrors r and l can be orthogonal to each other when the mirror surfaces 21 and 22 are orthogonal. In this embodiment, the total inclination angle of the inclined surfaces 26r and 26l is set to be 90 degrees, and for practical convenience, the inclination angle of each of the inclined surfaces 26r and 26l is relative to the mirror surfaces 21 and 22, respectively. Both are 45 degrees.
[0016]
By the way, both the surface mirror holders 23 and 24 must have a shape that allows close orthogonality of the inner end protruding portions of the surface mirrors r and l as described above. Therefore, the front mirror holder 23 has the outer end and upper and lower ends (three ends) of the surface mirror r held by a frame (not shown), and only the inner end is not held by the frame. It protrudes from 26r. Similarly, in the surface mirror holder 24, the outer end portion and upper and lower end portions of the surface mirror l are held by a frame (not shown), and only the inner end portion protrudes from the inner side surface 26l without being held by the frame. . Thus, since the inner end portions of both surface mirrors r and l are exposed from the inner side surfaces 26r and 26l, the inner end protruding portions of the surface mirrors r and l are in direct contact with each other in a state where the mirror surfaces 21 and 22 are orthogonal to each other. it can.
[0017]
On the other hand, since it is an absolute condition that the mirror crossing angle in an orthogonal mirror is strictly 90 degrees, even in the daily use environment of general users, the mirror surface contact state must be reliably reproduced every time the mirror surface is opened. For this purpose, even in the orthogonal mirror of this embodiment, the inner side surfaces 26r and 26l of the surface mirror holders 23 and 24 must be strongly pressed against each other in the orthogonal state of the mirror surfaces 21 and 22.
[0018]
That is, in the orthogonal mirror of this embodiment, a steel piece 30 as a magnetic body is attached to the inner side surface 26r of the surface mirror holder 23, and a magnet 29 is attached to the inner side surface 26l of the surface mirror holder 24. The magnet 29 and the steel piece 30 constituting the open state holding member are embedded so as to be flush with the inner side surfaces 26l and 26r, respectively. Therefore, when the surface mirror holders 23 and 24 are opened, the magnet 29 and the steel piece 30 approach each other, and as a result of the magnet 29 attracting the steel piece 30 strongly, the surface mirror holders 23 and 24 are always in a predetermined open state. The orthogonal state of the mirror surfaces 21 and 22 set in advance in the manufacturing process is reliably maintained. For this reason, it is not necessary for the user to consciously make the mirror surfaces 21 and 22 in an orthogonal state, and by simply bringing the magnet 29 and the steel piece 30 together, a strictly orthogonal state can be obtained and the orthogonal state is maintained. In addition, in order to reinforce the attractive force between the inner side surfaces 26r and 26l, the steel piece 30 may be replaced with a magnet.
[0019]
As described above, it is an absolute condition that the mirror crossing angle in the orthogonal mirror is strictly 90 degrees. For this purpose, first, in the manufacturing process, the crossing angle is finely adjusted in a quasi-orthogonal state in which the mirror surface is closely contacted. It must be possible to realize such an orthogonal state. In the orthogonal mirror of this embodiment, in order to realize this, a female screw (nut) 28 is embedded in the inner surface 26r of the surface mirror holder 23 so as to be flush with the female screw 28, and an adjusting screw (interval) is provided. The adjusting member 27 is screwed. A groove having a depth corresponding to the stroke of the adjustment screw 27 is formed in the surface mirror holder 23, and the adjustment screw 27 is fitted into this groove. When the inner side surfaces 26r, 26l of the surface mirror holders 23, 24 are brought together by the magnetic force of the magnet 29 and the steel piece 30, the heads of the adjusting screws 27 come into contact with the inner side surface 26l. The exact orthogonal state is reproduced.
[0020]
Fine adjustment of the crossing angle of the mirror surfaces 21 and 22 by the adjusting screw 27 is performed as follows. First, when the mirror images 21 and 22 are in close contact with each other, a scale image is projected on the orthogonal mirror, the adjustment screw 27 is rotated by, for example, a driver, and the scale double reflection image is left-right aligned, thereby realizing an accurate orthogonal state. In the manufacturing process, once the degree of protrusion of the adjustment screw 27 is fixed in this accurate orthogonal state, the accuracy of the opening operation of the user will be accurate every time the surface mirror holders 23 and 24 are opened, even if the user's opening operation is somewhat inaccurate. The orthogonal state of the mirror surfaces 21 and 22 is reproduced. Needless to say, the adjusting screw 27 does not necessarily have a screw shape as long as it is a member capable of adjusting the distance between the inner side surfaces 26r and 26l. For example, the adjusting screw 27 may be directly screwed to the surface mirror holder 23 or 24 without providing the female screw 28.
[0021]
Furthermore, since the head of the adjustment screw 27 abuts against the inner surface 261 of the surface mirror holder 24, further expansion of the both surface mirror holders 23, 24 can be suppressed, and damage due to excessive expansion. Can be prevented.
[0022]
