Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to two surface mirrors whose right and left mirror surfaces are opposed to each other in an upright posture and are orthogonal to each other, and the left and right of the target image are oriented through double reflection between the two surface mirrors. More particularly, the present invention relates to a folding orthogonal mirror that can take a folded shape or a plane mirror shape by making the mirror surface crossing angle of the left and right surface mirrors variable.

[0002]

2. Description of the Related Art In a conventional orthogonal mirror in which an object image is oriented by arranging two surface mirrors in a plane orthogonal to the left and right, the arrangement of the two surface mirrors is fixed. Japanese Patent Application No. 7-217034: "Viewing angle determining device, observation visual field positioning observation device, imaging visual field positioning imaging device, and target image orienting orthogonal mirror"). This is because the conventional technology related to the target image normalization orthogonal mirror is limited to the category of professional business technology such as a measurement device and an observation device.

[0003] On the other hand, from the standpoint of consumer base and general business use, since this technology is a technology realized as a three-dimensional shape in which a mirror is fixed in a plane orthogonal shape, a large space volume is required for transportation and the like. This is inconvenient for storage.

[0004]

SUMMARY OF THE INVENTION The present invention is not directed to a mirror image obtained by a conventional mirror, but to a face image or a full body image of a right-and-left relationship viewed by an opposing opponent. However, it is an object of the present invention to solve a morphological problem for making the target image-orientated orthogonal mirror foldable so as to be easily obtained.

[0005] In order to be able to fold the target-image-orientation orthogonal mirror, the left and right surface mirrors, which have been conventionally fixed, must be separated and reconnected. When two plate-like bodies are connected to be openable and closable, a commonly used connecting tool is a hinge. However, since the rotation axis of the hinge is outside the two rotors, a gap is inevitably created between the two blades when the two blades are in an orthogonal posture. The tangent line between the right and left mirror surfaces of the orthogonal mirror intended by the present invention is the center line having the most important role, and if that portion becomes a gap, it does not hold as an orthogonal mirror.

On the other hand, if the left and right mirror surfaces are made close to each other when the hinge wings are perpendicular to each other, the close mirror surface ends become an obstacle, and the left and right mirror surfaces cannot be closed. Thus, in order to enable the opening and closing of the rigid orthogonal mirror, it is impossible to use a general hinge,
Special solutions are needed. Accordingly, an object of the present invention is to provide an object-image-orientation orthogonal mirror capable of folding the left and right mirrors that can be folded or having the attitude of a single plane mirror. It is an object of the present invention to provide a foldable orthogonal mirror that solves (7). (1) A problem for reconnecting the left and right surface mirrors separated (2) A problem for reopening the both surface mirrors that can be opened and closed (3) The reconnection is performed in a plane orthogonal to both surface mirrors (4) Problems to realize a highly stable and accurate target image orientation mirror in the orthogonal state of both surface mirrors (5) In the orthogonal state of both surface mirrors, Problems to prevent gaps between mirror surfaces and to achieve close contact between both mirror surfaces. (6) Problems to eliminate the orthogonal state of both surface mirrors and return to the openable state of both surface mirrors again. (7) Both Issues for enabling a plane mirror posture with an open front mirror

[0007]

In order to achieve the above object, a folding orthogonal mirror according to claim 1 of the present invention comprises two surface mirrors each having a light reflecting surface, and two surface mirrors. Both surface mirrors can be moved to a folded state where the mirror surfaces of both surface mirrors face each other, and to a state where the side surface of one surface mirror is in close contact with the mirror surface of the other surface mirror and the mirror surfaces of both surface mirrors are orthogonal. And a connecting means for movably connecting the two with each other, whereby the technical problems (1) to (7) can be simultaneously solved.

According to a second aspect of the present invention, in the folding orthogonal mirror, the two surface mirrors are a stationary surface mirror and a rotating surface mirror each including a mirror surface and a mirror surface holding portion for holding the mirror surface from the back surface.

According to a third aspect of the present invention, in the folding orthogonal mirror, the two surface mirrors are a stationary surface mirror and a rotating surface mirror each comprising a mirror surface and a mirror surface holding portion for holding the mirror surface from the back surface. A stator mounted on an upper surface and / or a lower surface of a mirror holding portion of the stationary surface mirror so as to be movable in a direction parallel to the mirror surface, and a stator fixed on an upper surface and / or a lower surface of the mirror holding portion of the rotating surface mirror. One end is rotatably mounted on the movable stator on the stationary surface mirror side, and the other end is rotatably mounted on the stator on the rotating surface mirror side, and has a length allowing rotation of the rotating surface mirror. And the technical problems (1) to (7) can be simultaneously solved.

According to a fourth aspect of the present invention, the two surface mirrors each include a mirror surface and a mirror surface holding portion for holding the mirror surface from the back surface, and the connecting means includes one of both side surfaces of the front surface mirror. , A stator fixed to the upper surface and / or lower surface of each mirror surface holding portion of both surface mirrors, and an arm having one end rotatably mounted to the stator on one surface mirror side. A piece, an arm piece whose one end is rotatably attached to the stator on the other surface mirror side, and a fulcrum that rotatably connects the other ends of both arm pieces on the connector side. The technical problems (1) to (6) can be simultaneously solved.

In each of the orthogonal mirrors according to the first to fourth aspects, since the two surface mirrors are connected to each other so as to be rotatable and movable by the connecting means, the incident light beam reflected on one mirror surface is reflected on the other mirror surface. Through the double reflection, which is incident on
The shape of the target image normalization orthogonal mirror (mirror orthogonal shape) that emits reflected light beams whose right and left positions have been switched with respect to the incident light beam direction vector, and a folded shape in which both mirror surfaces face each other can be obtained.

In the orthogonal mirror according to any one of claims 1 to 4, the mirror orthogonal state is locked by providing the mirror orthogonality guarantee means for maintaining the mirror orthogonal state of both surface mirrors, so that the usability is improved.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments. FIG. 1 is a conceptual diagram illustrating the operation principle of the folding orthogonal mirror according to the present invention. The image of our face we see in a normal mirror is a mirror image. Structured lights incident from the target image
) Is specularly reflected by the mirror surface, so that the left-right relationship of the reflected image is a left-right inverted image of the image seen when the target image faces this direction from the mirror side.

On the other hand, the orthogonal mirror according to the present invention is a mirror in which two plane surface mirrors 11 and 12 are arranged in a posture (an inner angle of π / 2) where the mirror surfaces are orthogonal to each other as shown in FIG. 1A. is there. Due to the arrangement of the mirror orthogonal mirrors, for example, light incident on the right mirror surface 11 at an incident angle θ as shown in FIG. 1B is reflected at a reflection angle θ and enters the left mirror surface 12. Since the angle of incidence is {(π / 2) −θ}, the angle of reflection by the left mirror 12 is also {(π / 2) −θ}, and has a vector parallel and opposite to the light incident on the right mirror 11. Light is emitted. That is, the straight incident light that has entered the right mirror surface 11 at π / 4 is reflected as straight reflected light from the left mirror surface position that is just symmetric with respect to both mirror surface boundary lines 15.

In this way, the left and right sides of the structured light from the target image 13 are inverted via the double reflection, so that the target image 14 is obtained as if facing the other side of the mirror. In other words, in the case of a face image, the face image of another person can be seen by the orthogonal mirror. Here, it goes without saying that the roles of the left and right mirror surfaces are interchangeable. However, the planar surface mirrors 11 and 12 need to be surface mirrors whose surfaces are light reflecting surfaces. In a commonly used backside mirror whose backside is a mirror surface made by metal deposition or plating, the incident light is double refracted when transmitting through a transparent body such as glass on the front side, and the quality of the reflected image is significantly reduced. To be used, it does not stand use.

FIG. 2 shows a first embodiment according to claim 2 in which the folding orthogonal mirror of the present invention is embodied for general use (FIG. 2C).
And a conceptual configuration of a third embodiment (FIG. 2D) according to claim 4. As shown in FIG. 2C, the orthogonal mirror according to the first embodiment includes a right mirror r and a left mirror l.
And a connector 25 for rotatably connecting both surface mirrors r and l. The right front mirror r has a mirror surface 21 and a mirror holding portion 23 for holding the mirror surface 21 from the back surface.
Has a mirror surface 22 and a mirror surface holding portion 24 for holding the mirror surface 22 from the back surface. The mirror holding units 23 and 24 are
Any member may be used as long as it is a member that holds 22 from the back surface, and its material is not specified.

As shown in FIG. 2D, the orthogonal mirror according to the third embodiment has a right surface mirror r, a left surface mirror l, and a double surface mirror r,
It is composed of a plastic sheet-like connector 45 provided over both side surfaces of the mirror 1 and a support arm 46 that rotatably supports the two surface mirrors r and l. The right front mirror r has a mirror surface 41 and a mirror holding portion 43 for holding the mirror surface 41 from the back surface, and the left mirror mirror l has a mirror surface 42 and a mirror holding portion 44 for holding the mirror surface 42 from the back surface. Details of the third embodiment will be described later.

In the first embodiment, the left and right surface mirrors r and l are rotatably connected by a connector 25. In the third embodiment, the left and right surface mirrors r and l are connected to a plastic sheet-like connector 45. And realizes rotation about the inner surface edges of the left and right mirror surfaces 41 and 42 as a rotation axis, thereby eliminating the above-described obstacles caused by opening and closing the left and right mirror surfaces. In the folding orthogonal mirror according to the first embodiment, as shown in FIG. 2C, since the connector 25 is rotatably joined to each of the left and right mirror surface holding parts 23 and 24, the connector 25 and the surface mirror are connected. Due to the respective rotational movements of r and l, both mirror surfaces 21 and
2 can be opened and closed, and both mirror surfaces 21 and 22 can be orthogonal to the plane.

The orthogonal mirror according to the first embodiment will be described in detail with reference to a schematic plan view of FIG. 3 viewed from above. However, the relative dimensional ratio of each part is neglected for convenience of explanation. As shown in FIG. 3, the right surface mirror r is a stationary surface mirror, and includes a right mirror surface 21, a right mirror surface holding unit 23, and a right stator 26.
And The left surface mirror 1 is a rotating surface mirror and includes a left mirror surface 22, a left mirror surface holding unit 24, and a left stator 27.

As shown in FIG. 4L, the left stator 27 is fixed to the upper surface of the left mirror holding part 24, and its fixed position is basically a which is ２ of the thickness (2a) of the left front mirror l. Distance and the inner side surface 28 on the center line of the upper surface of the left surface mirror l.
From the distance a. On the other hand, the right stator 26 is fixed to the upper surface of the right surface mirror r (thickness 2a), and the fixed position is a position 3a away from the inner side surface 29 on the center line.

The connector 25 is rigid and has an opening 25 'at each end thereof (FIG. 4J).
The right mirror surface holding portion 23 is joined to the left mirror surface holding portion 24 by the left stator 27. Both openings 2
The distance between 5 ′ is 2√2a, which is the length of the hypotenuse of a right-angled isosceles triangle, as shown in FIG. 4L. FIG. 4J is a diagram illustrating a method of joining the connector 25 and the surface mirrors r and l by the stators 26 and 27. Since the joining method is the same for the left and right sides, the right mirror surface 21 and the right mirror surface holding unit 23 will be described here as an example, and the description of the left mirror surface 22 and the left mirror surface holding unit 24 will be omitted.

As shown in FIG. 4J, the stator 26 has a head 26 'having a larger diameter than the opening 25' of the connector 25, and a shaft portion 26 "having a smaller diameter. The part 26 'is slightly lifted from the upper surface of the mirror holding part 23, and the fixing part 26 "" of the shaft part 26 "is fixed to the mirror holding part 23 through the opening 25', so that the mirror holding part 23 and the connector 25 are connected. The loose connection enables the connector 25 to rotate independently around the stator 26, and the first opening / closing operation for realizing the mirror opening / closing operation shown in FIG. The condition is satisfied.

The second condition for enabling the mirror opening / closing operation by rotation of the connector 25 and the mirror surfaces 21 and 22 is as follows. First, the left surface mirror 1 composed of the left mirror surface 22 and the left mirror surface holding unit 24 is pulled.
The connector 25 is orthogonal to both mirror surfaces 21 and 22 (FIG. 3F),
Next, the left surface mirror 1 is rotated around the stator 27,
This is a condition that allows the right mirror surface 21 to be perpendicular (FIG. 3G). The condition is that the distance (2√2a) between the two openings 25 ′ of the stator 25 is the sum of the turning radius of the inner surface edge 32 of the left mirror surface 22 and the distance between the surface of the right surface mirror r and the center line of the upper surface. This is satisfied by being longer than (√2a + a).

As described above, the left and right surface mirrors r and l are connected to each other in a manner that allows the connector 25 to rotate itself and the left surface mirror l.
3E, the orthogonal mirror of the first embodiment is
From the closed state of the mirror-facing posture shown in FIG. 7, it is possible to reach the mirror-surface orthogonal posture shown in FIG. If the mirror orthogonal orientation (FIG. 3H) cannot provide high-precision mirror orthogonality, the target image to be projected is distorted, and is not established as a target image oriented orthogonal mirror. Conditions for high-precision mirror orthogonality are as follows:
That is, the mirror surface 21 of the stationary surface mirror r is closely contacted with high precision in a plane (FIG. 4M). To this end, the side surfaces 28 are finished with a high flatness.

Next, conditions for stably assuring the mirror orthogonal orientation shown in FIG. 3H will be described. The rotating surface mirror 1 has a tendency of “return rotation” to rotate toward the mirror surface 22 around the left stator 27 and a tendency to “over-rotation” to rotate toward the back surface 30 around the left stator 27 in the mirror orthogonal posture. Potentially have. Regarding the tendency of “return rotation”, as shown in the orthogonal posture side view of FIG. 4K, the rear surface (3
0: a notch (locking portion) 3 provided on the right mirror holding portion 23 with the projection 34 of the stopper 33 fixed to the right mirror surface holding portion 23 (not shown in FIG. 4K).
5 prevents this. Here, the mirror 33 and the concave portion 35 constitute a mirror orthogonality assurance means.

FIG. 4L shows the tendency of "overspeed".
As shown in the figure, the fixed position of the right stator 26 to the right mirror holding unit 23 and the fixed position of the left stator 27 to the left mirror holding unit 24 are two sides in the mirror orthogonal posture of the two mirror surfaces 21 and 22. Are both 2a. The length of the hypotenuse is the distance between the two openings 25 ′ of the connector 25 (2√2
Since it is the same as a), when the force of “over-rotation” is applied, the connector 25 is pulled by the two mirror-surface holding portions 23 and 24 to be tense, and the effect of the stopper is exerted to “over-rotate”. Has been prevented.

Next, conditions for eliminating the gap between the left and right mirror surfaces 21 and 22 will be described as prerequisites for the orthogonal mirror for normalizing the target image. This gap is a gap that may occur at the boundary 15 where the right mirror surface 11 and the left mirror surface 12 shown in FIG. Even in the conventional fixed-shape orthogonal mirror, the elimination of the gap was a serious problem.In particular, in the variable-shape orthogonal mirror of the present invention, the gap between the mirror surfaces was generated due to the movement of the mirror surfaces. It is easy. Therefore, it is necessary to prevent the generation of a gap between the left and right mirror surfaces in the mirror orthogonal posture.

In the folding orthogonal mirror according to the first embodiment, the left mirror surface 22 is extended to the inner side surface 28 of the left mirror surface holding portion 24 as shown in a plan view (FIG. 4M) from which the connector 25 is removed.
The right side surface 29 of the right mirror surface holding portion 23 extends beyond the inner surface edge 32 of the left mirror surface 22 when the right mirror surface 21 is in a mirror orthogonal posture.
When the mirror surfaces 21 and 22 are orthogonal to each other, the right mirror surface 21 and the edge 32 of the left mirror surface 22 are in close contact with each other, thereby preventing the occurrence of a gap between the left and right mirror surfaces 21 and 22. doing.

As described above, the right and left surface mirrors r and l by the connector 25
Is mainly described with reference to the top view of FIG. 3, the upper surface of both surface mirrors r and l. However, the folding orthogonal mirror of the first embodiment has the same configuration for the lower surface of both surface mirrors r and l. A mechanism is provided, and both surface mirrors r and l are stably opened and closed by vertical connection. Next, a folding orthogonal mirror according to a second embodiment of the present invention will be described. The second embodiment is a folding orthogonal mirror that realizes a plane mirror shape in which two surface mirrors are combined in a plane by making the fixed position of the stator of the first embodiment movable.

A mechanism for moving the fixed position of the stator according to the second embodiment will be described with reference to the schematic plan view of FIG. As shown in FIG. 5, the right stationary surface mirror r includes a right mirror surface 51, a right mirror surface holding portion 53 that holds the right mirror surface 51 from the back surface, and a stator moving structure (stator) provided in the right mirror surface holding portion 53. (A moving path) 60 and a right stator 56 movably provided in the structure 60. Also, the left rotating surface mirror l
A left mirror surface 52, a left mirror surface holding portion 54 for holding the left mirror surface 52 from the back surface, and a left stator 5 provided on the left mirror surface holding portion 54.
7 is provided.

One end of the connector 55 is rotatably connected to the right stator 56 of the right front mirror r, and the other end is rotatably connected to the left stator 57 of the left front mirror l. This rotatable joining method is the same as in the first embodiment. Next, FIG.
According to R, the stator moving structure 60 will be described. The stator moving structure 60 is parallel to the upper surface of the right surface mirror r along the center line of the thickness (2a) of the right surface mirror r. The rear end 62 of the structure 60 is located at a distance a equal to the distance from the right mirror surface 51 and the distance from the inner side surface 59 (FIG. 4).
L). However, the front end 63 and the rear end 6 of the stator moving structure 60
The description of the position 2 is all described as the center position of the base 56 ″ when the base 56 ″ of the right stator 56 described below is pressed against the front end 63 or the rear end 62. Therefore,
The foremost end and the rearmost end of the actual stator moving structure 60 are located forward or backward, respectively, by the radius of the base 56 "from the position described.

The length of the stator moving structure 60 is 2a. Therefore, the front end 63 is located at the center of the upper surface of the right front mirror r at a distance 3a from the inner side surface 59. On the other hand, the fixed position of the left stator 57 on the left front mirror 1 is the same as the fixed position of the left stator 27 on the left front mirror 1 in the first embodiment. As a result, both openings 5 of the connector 55
The distance between 5 ′ (FIG. 4N) is 2√2a (FIG. 4L).

Next, the right stator 56 and the stator moving structure 60
Will be described with reference to the cross-sectional view of FIG. 4N. The stator moving structure 60 has a narrow opening 60 "and a cavity 60 'having a wider width than the opening 60". Stator 56
Has a larger diameter than the opening 55 'of the connector 55,
Shaft 56 'has a smaller diameter than opening 55'. Also, the base 56 "of the right stator 56 has a diameter smaller than the width of the cavity 60 'and larger than the opening 60".

The base 56 "functionally belongs to the stator moving structure 60. The right stator 56 fixes the shaft 56 'to the base 56", and the base 56 "has the cavity 60'.
By moving inside, the movement of the right stator 56 is achieved. Since the stator moving structure 60 has the cross-sectional structure of FIG. 4N from its front end 63 to its rear end 62, the right stator 56 moves back and forth along the stator moving structure 60 and the mirror surface 51 of the right surface mirror r. Can be moved in a direction parallel to.
In the closed state of both mirror surfaces 51 and 52 in FIG.
Are pressed against the front end 63 of the stator moving structure 60.
Then, if the left surface mirror 1 is raised and pulled, the connector 55
Is perpendicular to the right surface mirror r, the inner side surface 58 of the left surface mirror 1 faces the right mirror surface 51, and then the left surface mirror 1 is rotated by 90 degrees about the left stator 57 to obtain FIG. Posture.

When the inner side surface 58 of the left front mirror 1 is pressed against the right mirror surface 51 in this position, the right stator 56 is pressed again to the front end 63 to take the orthogonal mirror position (FIG. 5S). Front end 63
As shown in the sectional view seen from above in FIG.
Since a spring-shaped stopper (elastic body) 61 is provided on the left and right inner sides of the 0 'as a mirror orthogonality assurance means, the base 56 "of the right stator 56 is temporarily fixed, as described in the first embodiment. This prevents the left surface mirror 1 from "over-rotating." The stopper 61 also has a temporary fixing function even when both mirror surfaces 51 and 52 in FIG.

In order to prevent the "return rotation" tendency, the tip of the stopper provided on the back surface of the left mirror holding portion 54 is provided on the inner side surface 59 of the right mirror holding portion 53 as in the first embodiment. The effect of prevention is exhibited by inserting it into the recess (not shown). Next, if the left front mirror 1 is separated again and pulled diagonally forward with a little force, the right stator 56 is prevented from slipping.
Breaks through provisional fixation by 1 and is released. When the left front mirror 1 is further pulled obliquely forward, the right stator 56 slides rightward in the stator moving structure 60 to reach the rear end 62. Then, when the left surface mirror 1 is rotated 90 degrees and the right stator 56 is pushed to the left, the inner side surface 58 of the left surface mirror 1 comes into close contact with the inner side surface 59 of the right surface mirror r. As a result, both mirror surfaces 51,
Since 52 constitutes the same plane, it becomes a plane mirror shown in FIG. 5T. Also in this plane mirror posture, the occurrence of the "return rotation" is prevented by inserting the tip of the stopper provided on the back surface of the left mirror holding portion 54 into the recess provided on the back surface of the right mirror holding portion 53. (Not shown).

As described above, the left and right surface mirrors r and l by the connector 55
Is mainly described with reference to FIG. 5 for the upper surface of both surface mirrors r and l. However, the folding orthogonal mirror of the second embodiment has the same mechanism for the lower surface of both surface mirrors r and l. The front and rear mirrors r and l are opened and closed by connecting the upper and lower surfaces. Next, a folding orthogonal mirror according to a third embodiment will be described. FIG. 6 is a schematic plan view for explaining the folding orthogonal mirror according to the third embodiment. However, the relative dimensional ratio of each part is neglected for convenience of explanation. FIGS. 6U and 6V are views showing a mirror-closed attitude and a mirror-orthogonal attitude of the third embodiment, respectively, and FIG. 6W is a view showing the structure and operation of a support arm.

In FIG. 6, the orthogonal mirror is a right surface mirror r,
The vehicle includes a left surface mirror l, a connector 75 formed of a plastic sheet material provided on both side surfaces of the both surface mirrors r and l, and a support arm 76 rotatably supporting the both surface mirrors r and l. The right surface mirror r has a right mirror surface 71 and a right mirror surface holding unit 73 that holds the right mirror surface 71 from the back surface.
It has a left mirror surface 72 and a left mirror surface holding portion 74 for holding the left mirror surface 72 from the back surface.

The support arm 76 includes two plate-like rigid bodies of a right arm (arm piece) 76a and a left arm (arm piece) 76.
The right arm 76a and the left arm 76b are rotatably connected to each other by a fulcrum 79. The right arm 76a is rotatably joined to the right mirror holding portion 73 by a right stator 77, and the left arm 76b is rotatably joined to the left mirror holding portion 74 by a left stator 78. These joining methods are the same as the methods described in the description of the first embodiment (FIG. 4J). The right arm 76a is an orthogonal stopper projecting toward the left arm 76b (mirror surface orthogonality assurance means).
81.

The connector 75 is mechanically connected to the two mirror-surface holders 73 and 74 by bonding them to one plane in which the inner side surfaces of the two mirror-surface holders 73 and 74 are aligned in a mirror-closed position. When the connector 75 is bent and stretched, both mirror surfaces 71 and 7 are moved.
The mirror surfaces 71 and 72 can be opened and closed using the tangent line 80 of the inner surface edge of the inner surface 2 (tangent line of the inner surface edges of both mirror surfaces in the orthogonal posture of the mirror surfaces 71 and 72, indicated by a contact point in the drawing) as a rotation axis. .

In the third embodiment, as shown in FIG. 6U, when the mirror surfaces 71 and 72 are closed, the support arm 76 is folded in a V-shape, and the angle between the right mirror surface 71 and the left mirror surface 72 is 0 degree. To keep. Also, as shown in FIG.
In the two orthogonal postures, the support arm 76 becomes linear, and the angle between the right mirror surface 71 and the left mirror surface 72 is fixed at 90 degrees. FIG. 6W is an enlarged view showing the function of the orthogonal stopper 81 of the right arm 76a for fixing the angle between the right mirror surface 71 and the left mirror surface 72 to 90 degrees. The posture of the left arm 76b in the closed posture of the mirror surfaces 71 and 72 is indicated by reference numeral 76b '. When the support arm 76 is opened with the fulcrum 79 as the center of rotation and the angle between the two surface mirrors r and l becomes 90 degrees, the support arm 76 is opened.
Is linear, and the orthogonal stopper 81 is
To prevent over-rotation and stop the further opening of the support arm 76, so that the left and right surface mirrors r and l are prevented from opening more than 90 degrees.

As described above, in the folding orthogonal mirror according to the third embodiment, the left and right mirror surfaces 71 and 72 can be opened and closed by connecting the left and right surface mirrors r and l with the plastic connector 75. The provision of the stopper 81 makes it possible to maintain the mirror surfaces 71 and 72 in a posture orthogonal to the mirror surfaces. As described above, the method of connecting the left and right surface mirrors r and l by the connector 75 has been described mainly on the upper surfaces of the both surface mirrors r and l with reference to the plan view of FIG. 6, but the folding orthogonal mirror of the third embodiment is A similar mechanism is provided for the lower surfaces of the front and rear mirrors r and l, and the front and rear mirrors r and l are opened and closed by vertical connection.

[0043]

As described above, according to the first to fourth aspects of the present invention, the two surface mirrors are connected by a structure in which the two surface mirrors can rotate by themselves. The shape of the mirror can be changed between a folded state and a mirror plane orthogonal state, and a foldable target image orientation orthogonal mirror with high stability and accuracy can be realized.

Further, according to the third aspect of the present invention, it is possible to take a plane mirror shape in which the mirror surfaces of the two surface mirrors are arranged on the same plane. In addition, according to the invention of claims 5 to 7, since the mirror orthogonal state is locked, usability is improved.
