本発明の一実施形態に係る死角補助装置を、図面を参照して説明する。   A blind spot assisting apparatus according to an embodiment of the present invention will be described with reference to the drawings.

図１は本実施形態に係る死角補助装置１００が配置される車両１の運転席付近の概観を示す図である。車両１は、図１に示すように、ステアリング１０と、ウインドシールドガラス２０と、サイドガラス３０，４０と、フロントピラー５０，６０と、を備える。また、２１，２２は、ウインドシールドガラス２０の周辺部に印刷形成される遮光性の黒セラ（黒セラミック）部である。   FIG. 1 is a view showing an overview of the vicinity of a driver's seat of a vehicle 1 in which a blind spot assisting device 100 according to the present embodiment is arranged. As shown in FIG. 1, the vehicle 1 includes a steering 10, a windshield glass 20, side glasses 30 and 40, and front pillars 50 and 60. Reference numerals 21 and 22 denote light-shielding black ceramic (black ceramic) portions that are printed on the periphery of the windshield glass 20.

車両１において、視認者（主に運転者）は、ウインドシールドガラス２０（黒セラ部２１の部分を除く）とサイドガラス３０，４０が配置される領域では風景を直接視認する一方、フロントピラー５０，６０と黒セラ部２１，２２が配置される領域ではフロントピラー５０，６０と黒セラ部２１，２２とによって視認者の視界が遮られ、風景を直接視認することができない死角領域が生じる。すなわち、フロントピラー５０，６０と黒セラ部２１，２２とは、本発明における障害物に該当する。   In the vehicle 1, a viewer (mainly a driver) directly sees the scenery in the area where the windshield glass 20 (excluding the black ceramic portion 21) and the side glasses 30 and 40 are arranged, while the front pillar 50, In the area where 60 and the black sera parts 21 and 22 are arranged, the front pillars 50 and 60 and the black sera parts 21 and 22 block the visual field of the viewer, resulting in a blind spot area where the landscape cannot be seen directly. That is, the front pillars 50 and 60 and the black ceramic portions 21 and 22 correspond to obstacles in the present invention.

次に、図１〜図３に基づいて本実施形態に係る死角補助装置１００の構成について説明する。なお、図２は、死角補助装置１００の概観を示す平面図であり、図３は、死角補助装置１００を示す斜視図である。
死角補助装置１００は、図１及び図２に示すように、視認者側から見て右側（運転者側）のフロントピラー５０に図示しないホルダ部材を介して配置され、フロントピラー５０及び黒セラ部２１によって遮られる死角領域の像を映すものである。なお、死角補助装置１００は、視認者から見てフロントピラー５０及び黒セラ部２１と対向するように配置される。 Next, the configuration of the blind spot assisting device 100 according to the present embodiment will be described based on FIGS. 2 is a plan view showing an overview of the blind spot assisting device 100, and FIG. 3 is a perspective view showing the blind spot assisting device 100. As shown in FIG.
As shown in FIGS. 1 and 2, the blind spot assisting device 100 is disposed via a holder member (not shown) on the front pillar 50 on the right side (driver side) when viewed from the viewer side. The image of the blind spot area blocked by 21 is projected. The blind spot assisting device 100 is disposed so as to face the front pillar 50 and the black ceramic portion 21 when viewed from the viewer.

死角補助装置１００は、図２及び図３に示すように、一対の平行平面ミラー（一対のミラー）１１０と、複数のルーバー（遮光部）１２１〜１２６を有する遮光部材１２０と、を備える。   As shown in FIGS. 2 and 3, the blind spot assisting device 100 includes a pair of parallel plane mirrors (a pair of mirrors) 110 and a light shielding member 120 having a plurality of louvers (light shielding portions) 121 to 126.

一対の平行平面ミラー１１０は、入射した光の一部を反射し一部を透過する半透過平面ミラー（半透過ミラー）１１１と、平面ミラー（ミラー）１１２とが互いに平行に対向するように配置されることによって構成される。なお、半透過平面ミラー１１１と平面ミラー１１２は図示しないホルダ部材に配置されることで平行な位置関係で固定される。なお、本発明の一対のミラーは、互いに対向するように配置されるものであれば完全な平行に配置されなくともよく、また、平面ミラーでなく曲面ミラーであってもよい。   The pair of parallel plane mirrors 110 are arranged such that a semi-transmission plane mirror (semi-transmission mirror) 111 that reflects a part of incident light and transmits a part thereof, and a plane mirror (mirror) 112 face each other in parallel. It is constituted by being done. The transflective flat mirror 111 and the flat mirror 112 are fixed in a parallel positional relationship by being arranged on a holder member (not shown). It should be noted that the pair of mirrors of the present invention need not be arranged completely in parallel as long as they are arranged so as to face each other, and may be curved mirrors instead of plane mirrors.

半透過平面ミラー１１１は、視認者側に配置され、例えばポリエチレンテレフタレート、ポリカーボネート、ポリエチレン、アクリル等の透光性の樹脂材料からなる基材の表面にアルミなどの金属を蒸着させることにより、所望の反射率を有するように反射率調整層を形成してなる。反射率調整層の厚さや種類などにより、反射率（透過率）が調整される。本実施形態の半透過平面ミラー１１１における透過光と反射光の光量比は、透過光：反射光＝１：９である。なお、半透過平面ミラー１１１は、基材の表面に誘電体多層膜をコーティングして形成してもよい。半透過平面ミラー１１１は、平面ミラー１１２と対向する基部１１１ａと基部１１１ａから延設される延設部１１１ｂとを有し、半透過平面ミラー１１１と平面ミラー１１２とが水平方向に段違い状となるように配置される。   The transflective flat mirror 111 is disposed on the viewer side, and by depositing a metal such as aluminum on the surface of a base material made of a translucent resin material such as polyethylene terephthalate, polycarbonate, polyethylene, acrylic, etc. A reflectance adjustment layer is formed so as to have reflectance. The reflectance (transmittance) is adjusted depending on the thickness and type of the reflectance adjusting layer. The light quantity ratio between the transmitted light and the reflected light in the transflective flat mirror 111 of this embodiment is transmitted light: reflected light = 1: 9. The transflective flat mirror 111 may be formed by coating the surface of a base material with a dielectric multilayer film. The transflective flat mirror 111 has a base 111a facing the flat mirror 112 and an extending portion 111b extending from the base 111a. The transflective flat mirror 111 and the flat mirror 112 are stepped in the horizontal direction. Are arranged as follows.

平面ミラー１１２は、その平面（反射面）が半透過平面ミラー１１１の平面（半透過反射面）と平行となるように配置されるものであり、例えば上述の透光性樹脂材料からなる基材の表面にアルミなどの金属を蒸着させてなる平面アルミ蒸着ミラーである。   The plane mirror 112 is arranged so that the plane (reflection surface) thereof is parallel to the plane (semi-transmission reflection surface) of the semi-transmission plane mirror 111. For example, the substrate made of the above-described translucent resin material is used. It is a flat aluminum vapor deposition mirror formed by vapor-depositing a metal such as aluminum on the surface.

半透過平面ミラー１１１と平面ミラー１１２とは、それぞれの平面（半透過反射面及び反射面）が、一対の平行平面ミラー１１０における光Ｌの進行方向（図３の矢印で示す）に対して垂直方向の幅が一対の平行平面ミラー１１０における光Ｌの進行方向に向かって徐々に小さくなるように、略楔状に形成されている。視認者の視野範囲から外れる不要個所を除去して小型化及び軽量化するためである。また、半透過平面ミラー１１１と平面ミラー１１２とは互いの平面形状が相似であり（ほぼ相似である場合を含む）、平面ミラー１１２の一対の平行平面ミラー１１０における光の進行方向Ｌに対して垂直方向の幅が、半透過平面ミラー１１１の一対の平行平面ミラー１１０における光Ｌの進行方向に対して垂直方向の幅よりも大きくなるように形成されている。斜め下あるいは斜め上から死角補助装置１００を見た場合に、上下方向で半透過平面ミラー１１１と平面ミラー１１２との間を遮光する図示しない遮光壁（例えば前記ホルダ部材の一部からなる）が映り込むことを抑制するためである。また、半透過平面ミラー１１１の入射側端部（入射側の側辺）Ｅ１０と、平面ミラー１１２の入射側端部（入射側の側辺）Ｅ１１とは、ウインドシールドガラス２０のガラス面に沿って傾斜している。ウインドシールドガラス２０のガラス面に近接して配置可能とするためである。   The semi-transmissive flat mirror 111 and the flat mirror 112 have their respective planes (semi-transmissive reflective surface and reflective surface) perpendicular to the traveling direction of light L (indicated by arrows in FIG. 3) in the pair of parallel flat mirrors 110. It is formed in a substantially wedge shape so that the width in the direction gradually decreases in the traveling direction of the light L in the pair of parallel flat mirrors 110. This is to reduce the size and weight by removing unnecessary portions that are out of the visual field range of the viewer. Further, the transflective flat mirror 111 and the flat mirror 112 are similar in plane shape to each other (including a case where they are substantially similar), and the light traveling direction L in the pair of parallel flat mirrors 110 of the flat mirror 112 is the same. The width in the vertical direction is formed to be larger than the width in the vertical direction with respect to the traveling direction of the light L in the pair of parallel flat mirrors 110 of the semi-transmissive flat mirror 111. When the blind spot assisting device 100 is viewed from obliquely below or obliquely above, a light shielding wall (not shown) (for example, comprising a part of the holder member) that shields light between the semi-transmissive planar mirror 111 and the planar mirror 112 in the vertical direction. This is to suppress the reflection. Further, the incident side end (incident side side) E10 of the transflective flat mirror 111 and the incident side end (incident side side) E11 of the flat mirror 112 are along the glass surface of the windshield glass 20. Is inclined. This is because it can be placed close to the glass surface of the windshield glass 20.

遮光部材１２０は、半透過平面ミラー１１１の視認者側の平面に設けられる非透光性部材であり、例えば黒色の合成樹脂材料からなる。遮光部材１２０は、半透過平面ミラー１１１の外形に応じた枠部１２７に、半透過平面ミラー１１１の視認者側の平面に沿って複数のルーバー１２１〜１２６が設けられてなる。ルーバー１２１〜１２６は、遮光部材１２０と同様の材料からなる非透光性の板状部である。なお、図２においては図を見やすくするために枠部１２７を省略して図示している。また、ルーバー１２１〜１２６は、その先端部が視認者側を向くように半透過平面ミラー１１１の視認者側の平面に対して所定の角度傾いて配置される。ルーバー１２１〜１２６の作用については後で詳述する。   The light shielding member 120 is a non-translucent member provided on the viewer-side plane of the transflective flat mirror 111, and is made of, for example, a black synthetic resin material. The light shielding member 120 is provided with a plurality of louvers 121 to 126 along a viewer-side plane of the semi-transmissive flat mirror 111 on a frame 127 corresponding to the outer shape of the semi-transmissive flat mirror 111. The louvers 121 to 126 are non-light-transmitting plate-like parts made of the same material as the light shielding member 120. In FIG. 2, the frame portion 127 is omitted for easy understanding of the drawing. In addition, the louvers 121 to 126 are disposed at a predetermined angle with respect to the viewer-side plane of the semi-transmissive flat mirror 111 so that the tip portions thereof face the viewer. The operation of the louvers 121 to 126 will be described in detail later.

次に、図２を用いて、一対の平行平面ミラー１１０の作用について説明する。なお、図２は、視認者が運転席に着座した状態を示しており、２は視認者の視点（アイポイント）を示している。   Next, the operation of the pair of parallel flat mirrors 110 will be described with reference to FIG. FIG. 2 shows a state in which the viewer is seated on the driver's seat, and 2 shows the viewer's viewpoint (eye point).

図２において、視認者（視点２）の前方視界には、フロントピラー５０（図示しないが黒セラ部２１も含む）によって遮られる死角領域Ｄが生じる。したがって、視点２からは死角領域Ｄに存在する物体Ｍを直接視認することができない。
一方、物体Ｍからの光Ｌは、一対の平行平面ミラー１１０に入射し、一対の平行平面ミラー１１０の間で反射を繰り返しつつ、一部の光Ｌは一対の平行平面ミラー１１０から出射する（半透過平面ミラー１１１を透過する）。なお、一対の平行平面ミラー１１０に入射し、一対の平行平面ミラー１１０の間で反射を繰り返すのは一対の平行平面ミラー１１０の平行な平面に対して傾きを有する光である。一対の平行平面ミラー１１０から出射する光Ｌの一部は、視点２に達する。したがって、視点２からは直接視認できる風景と連続して平面ミラー１１２に映る物体Ｍの像を半透過平面ミラー１１１越しに視認することができる。なお、死角領域Ｄのうちフロントピラー５０の背面側の僅かな領域（ハッチングで示す部分）は、この領域からの光が一対の平行平面ミラー１１０に入射できず、その像を一対の平行平面ミラー１１０によって映すことができないが、それ以外の殆どの領域において死角領域Ｄの像を一対の平行平面ミラー１１０によって映すことができる。
なお、死角領域Ｄの像を一対の平行平面ミラー１１０によって映すに当たって、視認者は、死角補助装置１００をフロントピラー５０の任意の高さ（視点２に合った高さ）に、一対の平行平面ミラー１１０に死角領域Ｄの像が映るように、すなわち、死角領域Ｄからの光Ｌが視点２に達するように一対の平行平面ミラー１１０の角度を調整して配置する。半透過平面ミラー１１１と平面ミラー１１２とは互いの位置関係が平行に固定されるため、一度の配置作業で一対の平行平面ミラー１１０を同時に配置することができ、また、一度の調整作業で一対の平行平面ミラー１１０の角度を同時に調整することができる。 In FIG. 2, a blind spot area D that is blocked by a front pillar 50 (not shown, but also including the black ceramic portion 21) is generated in the front view of the viewer (viewpoint 2). Accordingly, the object M present in the blind spot area D cannot be directly viewed from the viewpoint 2.
On the other hand, the light L from the object M is incident on the pair of parallel plane mirrors 110 and is repeatedly reflected between the pair of parallel plane mirrors 110 while a part of the light L is emitted from the pair of parallel plane mirrors 110 ( The light passes through the semi-transmissive flat mirror 111). The light incident on the pair of parallel plane mirrors 110 and repeatedly reflected between the pair of parallel plane mirrors 110 is light having an inclination with respect to the parallel plane of the pair of parallel plane mirrors 110. Part of the light L emitted from the pair of parallel flat mirrors 110 reaches the viewpoint 2. Therefore, the image of the object M reflected on the plane mirror 112 can be viewed through the transflective plane mirror 111 continuously with the scenery that can be directly viewed from the viewpoint 2. In addition, in a small area on the back side of the front pillar 50 (the part indicated by hatching) in the blind spot area D, light from this area cannot enter the pair of parallel plane mirrors 110, and the image is displayed as a pair of parallel plane mirrors. 110, the image of the blind spot area D can be projected by the pair of parallel plane mirrors 110 in almost all other areas.
Note that when the image of the blind spot area D is projected by the pair of parallel plane mirrors 110, the viewer places the blind spot assisting device 100 at an arbitrary height of the front pillar 50 (a height suitable for the viewpoint 2) and a pair of parallel planes. The angle of the pair of parallel plane mirrors 110 is adjusted so that the image of the blind spot area D is reflected on the mirror 110, that is, the light L from the blind spot area D reaches the viewpoint 2. Since the positional relationship between the transflective flat mirror 111 and the flat mirror 112 is fixed in parallel with each other, the pair of parallel flat mirrors 110 can be arranged at the same time by a single arranging operation, and the pair of parallel mirrors 110 can be arranged by a single adjusting operation. The angles of the parallel plane mirrors 110 can be adjusted simultaneously.

ところで、光Ｌは一対の平行平面ミラー１１０の間で反射を繰り返すので、光Ｌが半透過平面ミラー１１１にｎ回入射した場合、物体Ｍの像を示すｎ個の光Ｌが１つの平行平面ミラー１１０から出射される。すなわち、一対の平行平面ミラー１１０からは視点２の左右方向に沿って、ｎ個の物体Ｍの像を示す光Ｌが出射することとなる。したがって、視認者は左右方向の広い範囲で物体Ｍの像を視認することができる。なお、一対の平行平面ミラー１１０から出射される光Ｌは半透過平面ミラー１１１での反射回数が増加するのに伴って輝度が低下する。   By the way, since the light L is repeatedly reflected between the pair of parallel plane mirrors 110, when the light L is incident n times on the semi-transmissive plane mirror 111, n light L indicating an image of the object M is one parallel plane. The light is emitted from the mirror 110. That is, light L indicating images of n objects M is emitted from the pair of parallel flat mirrors 110 along the horizontal direction of the viewpoint 2. Therefore, the viewer can view the image of the object M in a wide range in the left-right direction. Note that the luminance of the light L emitted from the pair of parallel plane mirrors 110 decreases as the number of reflections by the transflective plane mirror 111 increases.

次に、図４を用いて、ルーバー１２１〜１２６の作用について説明する。なお、図４は、死角補助装置１００を手前側上方から見た図であり、図４においては図を見やすくするために遮光部材１２０の枠部１２７を省略して図示している。   Next, the operation of the louvers 121 to 126 will be described with reference to FIG. 4 is a view of the blind spot assisting device 100 as viewed from the upper front side. In FIG. 4, the frame portion 127 of the light shielding member 120 is omitted in order to make the drawing easier to see.

一対の平行平面ミラー１１０には、死角領域Ｄからの光Ｌ以外に視認者（視点２）側からも外光が入射する。視認者側から一対の平行平面ミラー１１０に入射する外光のうち、図２に示すように、特に半透過平面ミラー１１１の平面の垂線Ｐに対して光Ｌの入射側に傾いて半透過平面ミラー１１１に入射する光（以下、迷光ＳＬという）は、その一部が半透過平面ミラー１１１で視点２に向かって反射され、あるいは一部が半透過平面ミラー１１１を透過して平面ミラー１１２で反射されて、再度半透過平面ミラー１１１から視点２に向かって出射され、平面ミラー１１２に映る物体Ｍの像の視認性を低下させる要因となる。これに対し、死角補助装置１００は、半透過平面ミラー１１１の視認者側の平面にルーバー１２１〜１２６を設けることによって、半透過平面ミラー１１１に入射する迷光ＳＬを遮って高い視認性を確保することができる。なお、ルーバー１２１〜１２６の長さ及び個数は、半透過平面ミラー１１１によって視点２に向けて反射されうる迷光ＳＬを遮る機能を果たすとともに、視点２からの視界を過度に遮らないように適宜定められる。すなわち、ルーバー１２１〜１２６は、その長さが長いほど１個のルーバーで多くの迷光ＳＬを遮ることができるものの、ルーバー自体が視点２からの視界を遮るおそれがある。これに対し、複数のルーバー１２１〜１２６を設けることでルーバー各々の長さを低減することができる。本実施形態では、６つのルーバー１２１〜１２６で迷光ＳＬを遮る機能を果たしている。なお、迷光ＳＬの全てがルーバー１２１〜１２６で遮られることが望ましいが、一部が遮られる場合であっても視認性向上の効果を得ることができる。   In addition to the light L from the blind spot area D, external light also enters the pair of parallel flat mirrors 110 from the viewer (viewpoint 2) side. Of the external light incident on the pair of parallel plane mirrors 110 from the viewer side, as shown in FIG. 2, the semitransparent plane is inclined particularly toward the incident side of the light L with respect to the normal P of the plane of the semitransparent plane mirror 111 A part of the light incident on the mirror 111 (hereinafter referred to as stray light SL) is reflected toward the viewpoint 2 by the semi-transmissive flat mirror 111, or a part of the light is transmitted through the semi-transmissive flat mirror 111 and transmitted by the flat mirror 112. The light is reflected and emitted again from the semi-transmissive flat mirror 111 toward the viewpoint 2, and becomes a factor of reducing the visibility of the image of the object M reflected on the flat mirror 112. In contrast, the blind spot assisting device 100 provides high visibility by blocking the stray light SL incident on the semi-transmissive flat mirror 111 by providing the louvers 121 to 126 on the viewer-side plane of the semi-transmissive flat mirror 111. be able to. The length and number of the louvers 121 to 126 are determined as appropriate so that the semi-transmissive flat mirror 111 functions to block the stray light SL that can be reflected toward the viewpoint 2 and does not excessively block the view from the viewpoint 2. It is done. In other words, the longer the length of the louvers 121 to 126, the more louvers themselves can block the stray light SL with one louver, but the louvers themselves may block the view from the viewpoint 2. On the other hand, the length of each louver can be reduced by providing a plurality of louvers 121-126. In the present embodiment, the six louvers 121 to 126 fulfill the function of blocking the stray light SL. Although all of the stray light SL is desirably blocked by the louvers 121 to 126, the effect of improving the visibility can be obtained even when some of the stray light SL is blocked.

次に、ルーバー１２１〜１２６の配置位置及び角度について図３及び図５を用いて説明する。なお、図５は、死角補助装置１００を手前側上方から見た図であり、図５においては図を見やすくするために遮光部材１２０の枠部１２７を省略して図示している。   Next, the arrangement positions and angles of the louvers 121 to 126 will be described with reference to FIGS. FIG. 5 is a view of the blind spot assisting device 100 as viewed from the upper front side. In FIG. 5, the frame portion 127 of the light shielding member 120 is omitted in order to make the drawing easier to see.

視点２から一対の平行平面ミラー１１０の平面を視認すると、ルーバー１２１〜１２６の各々は、死角領域Ｄを含む前方視界における上下方向の線として視認される。また、平面ミラー１１２の入射側端部Ｅ１１も同様に視点２から見て前方視界における上下方向の線として視認される。さらに、平面ミラー１１２の入射側端部Ｅ１１は、半透過平面ミラー１１１で反射され、平面ミラー１１２に映り込む複数の入射側端部の像Ｅ１２〜Ｅ１４が同様に視点２から見て前方視界における上下方向の線として視認される。これらの線が全て別々に視認されると死角補助装置１００の視認性が損なわれるおそれがある。これに対し、本実施形態においては、ルーバー１２１〜１２６のうち、ルーバー１２３〜１２６を、基準視点位置として定める視点２から見て、平面ミラー１１２の入射側端部Ｅ１１あるいは入射側端部の像Ｅ１２〜Ｅ１４と重なるように配置し、前方視界における上下方向の線を低減してルーバー１２１〜１２６を設ける構成であっても良好な視認性を確保している。
具体的には、まず図３に示すように、一対の平行平面ミラー１１０の平面側から見て、ルーバー１２３〜１２６を平面ミラー１１２の入射側端部（入射側の側辺）Ｅ１１と平行となる角度に設ける。
そして図５に示すように、ルーバー１２３を視点２から見て入射側端部Ｅ１１と重なるように、視点２と入射側端部Ｅ１１とを結ぶ直線Ｓ１上に配置する。直線Ｓ１は、視点２から見て半透過平面ミラー１１１を介して背景を視認する領域（１回目）と、半透過平面ミラー１１１、平面ミラー１１２の順で光Ｌが反射されて、再度（２回目）半透過平面ミラー１１１に入射する像を視認する領域との境界である。
また、ルーバー１２４を視点２から見て平面ミラー１１２に映り込む入射側端部の像Ｅ１２と重なるように、視点２と入射側端部Ｅ１１から一対の平行平面ミラー１１０の平面に対して垂直方向に半透過平面ミラー１１１と平面ミラー１１２との間隔Ａを２回分移動した点Ｅ２１とを結ぶ直線Ｓ２上に配置する。直線Ｓ２は、２回目に半透過平面ミラー１１１に入射する像とさらに半透過平面ミラー１１１、平面ミラー１１２の順で光Ｌが反射されて、再度（３回目）半透過平面ミラー１１１に入射する像を視認する領域との境界であり、平面ミラー１１２の入射側端部の像Ｅ１２は直線Ｓ２上で視認されるためである。
また、ルーバー１２５を視点２から見て平面ミラー１１２に映り込む入射側端部の像Ｅ１３と重なるように、視点２と点Ｅ２１から一対の平行平面ミラー１１０の平面に対して垂直方向に間隔Ａをさらに２回分移動した点Ｅ３１とを結ぶ直線Ｓ３上に配置する。直線Ｓ３は、３回目に半透過平面ミラー１１１に入射する像とさらに半透過平面ミラー１１１、平面ミラー１１２の順で光Ｌが反射されて、再度（４回目）半透過平面ミラー１１１に入射する像を視認する領域との境界であり、平面ミラー１１２の入射側端部の像Ｅ１３は直線Ｓ３上で視認されるためである。
また、ルーバー１２６を視点２から見て平面ミラー１１２に映り込む入射側端部の像Ｅ１４と重なるように、視点２と点Ｅ３１から一対の平行平面ミラー１１０の平面に対して垂直方向に間隔Ａをさらに２回分移動した点Ｅ４１とを結ぶ直線Ｓ４上に配置する。直線Ｓ４は、４回目に半透過平面ミラー１１１に入射する像とさらに半透過平面ミラー１１１、平面ミラー１１２の順で反射されて、再度（５回目）半透過平面ミラー１１１に入射する像を視認する領域との境界であり、平面ミラー１１２の入射側端部の像Ｅ１３は直線Ｓ４上で視認されるためである。 When the planes of the pair of parallel flat mirrors 110 are viewed from the viewpoint 2, each of the louvers 121 to 126 is viewed as a vertical line in the front field of view including the blind spot area D. Similarly, the incident-side end E11 of the flat mirror 112 is visually recognized as a vertical line in the forward field of view when viewed from the viewpoint 2. Further, the incident side end E11 of the plane mirror 112 is reflected by the semi-transmissive plane mirror 111, and a plurality of incident side end images E12 to E14 reflected on the plane mirror 112 are similarly viewed from the viewpoint 2 in the forward view. It is visually recognized as a vertical line. If all of these lines are viewed separately, the visibility of the blind spot assisting device 100 may be impaired. On the other hand, in the present embodiment, of the louvers 121 to 126, the louvers 123 to 126 are viewed from the viewpoint 2 that is defined as the reference viewpoint position, and an image of the incident side end E11 or the incident side end of the plane mirror 112 is obtained. Even if it is arranged so as to overlap with E12 to E14 and the louvers 121 to 126 are provided by reducing the vertical line in the front field of view, good visibility is ensured.
Specifically, as shown in FIG. 3, when viewed from the plane side of the pair of parallel plane mirrors 110, the louvers 123 to 126 are parallel to the incident side end (incident side side) E11 of the plane mirror 112. Provide an angle.
Then, as shown in FIG. 5, the louver 123 is arranged on a straight line S1 connecting the viewpoint 2 and the incident side end E11 so as to overlap the incident side end E11 when viewed from the viewpoint 2. The straight line S1 reflects the light L in the order of the region (first time) in which the background is viewed through the semi-transmissive flat mirror 111 as viewed from the viewpoint 2, the semi-transmissive flat mirror 111, and the flat mirror 112 in this order, and again (2 The second) is a boundary with a region where an image incident on the semi-transmissive flat mirror 111 is visually recognized.
Also, the louver 124 is perpendicular to the plane of the pair of parallel plane mirrors 110 from the viewpoint 2 and the incident side end E11 so as to overlap the image E12 of the incident side end reflected on the plane mirror 112 when viewed from the viewpoint 2. Are arranged on a straight line S2 connecting a point E21 that has moved the distance A between the semi-transmissive flat mirror 111 and the flat mirror 112 twice. In the straight line S2, the light L is reflected in the order of the image incident on the semi-transmissive flat mirror 111 for the second time, the semi-transmissive flat mirror 111, and the flat mirror 112 in this order, and is incident on the semi-transmissive flat mirror 111 again (third time). This is because the image E12 at the incident side end of the plane mirror 112 is visually recognized on the straight line S2, which is a boundary with the region where the image is viewed.
Further, the distance A in the direction perpendicular to the plane of the pair of parallel plane mirrors 110 from the viewpoint 2 and the point E21 is overlapped with the image E13 of the incident side end portion reflected on the plane mirror 112 when the louver 125 is viewed from the viewpoint 2. Are arranged on a straight line S3 connecting the point E31 that has been moved twice more. In the straight line S3, the light L is reflected in the order of the image which is incident on the semi-transmissive flat mirror 111 for the third time, and further in the order of the semi-transmissive flat mirror 111 and the flat mirror 112, and is incident on the semi-transmissive flat mirror 111 again (fourth time). This is because the image E13 at the incident side end of the plane mirror 112 is visually recognized on the straight line S3.
In addition, a distance A in the direction perpendicular to the plane of the pair of parallel plane mirrors 110 from the viewpoint 2 and the point E31 so that the louver 126 overlaps with the image E14 of the incident side end reflected on the plane mirror 112 when viewed from the viewpoint 2. Are arranged on a straight line S4 connecting the point E41 that has been moved twice more. The straight line S4 is reflected in the order of the image which is incident on the semi-transmissive flat mirror 111 for the fourth time, and further the semi-transmissive flat mirror 111 and the plane mirror 112 in this order, and the image which is incident on the semi-transmissive flat mirror 111 again (fifth time) is visually recognized. This is because the image E13 at the incident side end of the plane mirror 112 is visually recognized on the straight line S4.

また同様に、視点２から一対の平行平面ミラー１１０の平面を視認すると、半透過平面ミラー１１１の入射側端部Ｅ１０も視点２から見て前方視界における上下方向の線として視認される。これに対し、本実施形形態は、ルーバー１２１〜１２６のうち、ルーバー１２１を、基準視点位置として定められる視点２から見て、半透過平面ミラー１１１と重なるように配置し、前方視界における上下方向の線を低減してルーバー１２１〜１２６を設ける構成であっても良好な視認性を確保している。
具体的には、まず図３に示すように、ルーバー１２１を半透過平面ミラー１１１の入射側端部（入射側の側辺）Ｅ１０と重なるように設ける。
そして、図５に示すように、ルーバー１２１を視点２から見て入射側端部Ｅ１０と重なるように、視点２と入射側端部Ｅ１０とを結ぶ直線Ｓ０上に配置する。直線Ｓ１は、視点２から見て直接背景を視認する領域と半透過平面ミラー１１１を介して背景を視認する領域との境界である。 Similarly, when the planes of the pair of parallel plane mirrors 110 are viewed from the viewpoint 2, the incident side end E10 of the semi-transmissive plane mirror 111 is also viewed as a vertical line in the forward field of view as viewed from the viewpoint 2. In contrast, in the present embodiment, among the louvers 121 to 126, the louver 121 is arranged so as to overlap with the semi-transmissive flat mirror 111 when viewed from the viewpoint 2 defined as the reference viewpoint position, and the vertical direction in the front field of view. Even if it is the structure which provides the louvers 121-126 by reducing this line, favorable visibility is ensured.
Specifically, as shown in FIG. 3, first, the louver 121 is provided so as to overlap the incident side end (incident side side) E <b> 10 of the semi-transmissive flat mirror 111.
Then, as shown in FIG. 5, the louver 121 is arranged on a straight line S0 connecting the viewpoint 2 and the incident side end E10 so as to overlap the incident side end E10 when viewed from the viewpoint 2. The straight line S <b> 1 is a boundary between a region where the background is visually recognized directly from the viewpoint 2 and a region where the background is visually recognized via the semi-transmissive flat mirror 111.

ルーバー１２１〜１２６のうち、ルーバー１２２は、ルーバー１２１の長さを低減するためにルーバー１２１とルーバー１２３との間に設けられる。ルーバー１２２の半透過平面ミラー１１１の平面に対する角度θ２は、ルーバー１２１の半透過平面ミラー１１１の平面に対する角度θ１と同様とした（θ１＝θ２）。   Of the louvers 121 to 126, the louver 122 is provided between the louver 121 and the louver 123 in order to reduce the length of the louver 121. The angle θ2 of the louver 122 with respect to the plane of the semi-transmissive flat mirror 111 is the same as the angle θ1 of the louver 121 with respect to the plane of the semi-transmissive flat mirror 111 (θ1 = θ2).

このように、ルーバー１２１〜１２６を配置すると、ルーバー１２１〜１２６の半透過平面ミラー１１１の平面に対する角度θ１〜θ６が、入射側から出射側に向かって（一対の平行平面ミラー１１０の光Ｌの進行方向に向かって）段階的に大きくなるように設けられることとなる（θ１＝θ２＜θ３＜θ４＜θ５＜θ６）。   As described above, when the louvers 121 to 126 are arranged, the angles θ1 to θ6 of the louvers 121 to 126 with respect to the plane of the semi-transmissive flat mirror 111 are changed from the incident side to the outgoing side (the light L of the pair of parallel flat mirrors 110). It is provided so as to increase stepwise (toward the traveling direction) (θ1 = θ2 <θ3 <θ4 <θ5 <θ6).

以上の構成からなる死角補助装置１００は、車両１内の障害物によって遮られる死角領域Ｄの像を映す死角補助装置１００であって、
前記像を表す光Ｌを入射し、視認者側に設けられ光Ｌの一部を反射し一部を透過する半透過平面ミラー１１１と、光Ｌを半透過平面ミラー１１１へ反射する平面ミラー１１２とが互いに対向するように配置される一対の平行平面ミラー１１０と、
半透過平面ミラー１１１の視認者側に設けられ、視認者側から半透過平面ミラー１１１に所定の角度で入射する迷光ＳＬを遮る複数のルーバー１２１〜１２６と、を備えてなる。
これにより、一対の平行平面ミラー１１０の一方に半透過平面ミラー１１１を用いたため、視認者は半透過平面ミラー１１１越しに平面ミラー１１２に映る物体Ｍの像及び風景を視認することができ、一対の平行平面ミラー１１０の配置位置の自由度が増し、より容易に視認者が直接視認する像（風景）と連続して死角領域Ｄの像を映すことが可能となる。また、死角領域Ｄを撮像するカメラ及び撮像画像を表示する表示器が不要であるためこれらを使用する場合と比較して安価である。また、複数のルーバー１２１〜１２６によって迷光ＳＬが半透過平面ミラー１１１に入射することを防ぐことができ、視認性を向上させることができる。 The blind spot assisting device 100 configured as described above is a blind spot assisting device 100 that displays an image of the blind spot area D that is blocked by an obstacle in the vehicle 1.
The light L representing the image is incident, the semi-transparent flat mirror 111 provided on the viewer side that reflects part of the light L and transmits part of the light L, and the flat mirror 112 that reflects the light L to the semi-transmissive flat mirror 111. A pair of parallel flat mirrors 110 arranged so as to face each other;
A plurality of louvers 121 to 126 which are provided on the viewer side of the semi-transmissive flat mirror 111 and block stray light SL incident on the semi-transmissive flat mirror 111 from the viewer side at a predetermined angle.
Accordingly, since the semi-transmissive flat mirror 111 is used as one of the pair of parallel flat mirrors 110, the viewer can visually recognize the image and landscape of the object M reflected on the flat mirror 112 through the semi-transmissive flat mirror 111. The degree of freedom of the arrangement position of the parallel plane mirror 110 is increased, and the image of the blind spot area D can be projected more easily and continuously with the image (landscape) that the viewer can directly visually recognize. In addition, since a camera that captures the blind spot area D and a display that displays the captured image are unnecessary, the cost is lower than when these are used. Further, the plurality of louvers 121 to 126 can prevent the stray light SL from entering the semi-transmissive flat mirror 111, and can improve visibility.

また、複数のルーバー１２１〜１２６の少なくとも一部（ルーバー１２３〜１２６）は、任意に定められる基準視点位置（視点２）から見て平面ミラー１１２の入射側端部Ｅ１１あるいは平面ミラー１１２に映り込む平面ミラー１１２の入射側端部の像Ｅ１２〜Ｅ１４と重なるように配置されてなる。
これによれば、前方視界における上下方向の線を低減してルーバー１２１〜１２６を設ける構成であっても良好な視認性を確保することができる。
なお、本実施形態においては、ルーバー１２３〜１２６が直線Ｓ１〜Ｓ４上に位置するように配置されるものであったが、視点２から見てルーバー１２３〜１２６が平面ミラー１１２の入射側端部Ｅ１１あるいは平面ミラー１１２の入射側端部の像Ｅ１２〜Ｅ１４と重なるためには、ルーバー１２３〜１２６の各々の少なくとも一部が直線Ｓ１〜Ｓ４と重なるように配置すればよい。この場合、ルーバー１２３〜１２６は視点２から見て幅のある上下方向の線として視認される。 In addition, at least some of the plurality of louvers 121 to 126 (louvers 123 to 126) are reflected on the incident side end E11 of the plane mirror 112 or the plane mirror 112 when viewed from an arbitrarily determined reference viewpoint position (viewpoint 2). It arrange | positions so that it may overlap with the images E12-E14 of the incident side edge part of the plane mirror 112. FIG.
According to this, even if it is the structure which reduces the line of the up-down direction in a front view, and provides the louvers 121-126, favorable visibility can be ensured.
In the present embodiment, the louvers 123 to 126 are arranged so as to be positioned on the straight lines S1 to S4. However, the louvers 123 to 126 are the incident side end portions of the plane mirror 112 when viewed from the viewpoint 2. In order to overlap E11 or the images E12 to E14 of the incident side end of the plane mirror 112, at least a part of each of the louvers 123 to 126 may be arranged to overlap the straight lines S1 to S4. In this case, the louvers 123 to 126 are visually recognized as vertical lines having a width when viewed from the viewpoint 2.

また、ルーバー１２１〜１２６のうち１つ（ルーバー１２１）は、任意に定められる基準視点位置（視点２）から見て半透過平面ミラー１１１の入射側端部Ｅ１０と重なるように配置されてなる。
これによれば、前方視界における上下方向の線を低減してルーバー１２１〜１２６を設ける構成であっても良好な視認性を確保することができる。
なお、本実施形態においては、ルーバー１２１が直線Ｓ０上に位置するように配置されるものであったが、視点２から見てルーバー１２１が半透過平面ミラー１１１の入射側端部Ｅ１０と重なるためには、ルーバー１２１の少なくとも一部が直線Ｓ０と重なるように配置すればよい。この場合、ルーバー１２１は視点２から見て幅のある上下方向の線として視認される。 Further, one of the louvers 121 to 126 (louver 121) is arranged so as to overlap the incident side end E10 of the semi-transmissive flat mirror 111 when viewed from an arbitrarily determined reference viewpoint position (viewpoint 2).
According to this, even if it is the structure which reduces the line of the up-down direction in a front view, and provides the louvers 121-126, favorable visibility can be ensured.
In the present embodiment, the louver 121 is disposed so as to be positioned on the straight line S0. However, the louver 121 overlaps the incident side end E10 of the semi-transmissive flat mirror 111 when viewed from the viewpoint 2. The louver 121 may be arranged so that at least a part of the louver 121 overlaps the straight line S0. In this case, the louver 121 is visually recognized as a vertical line having a width as viewed from the viewpoint 2.

また、複数のルーバー１２１〜１２６は、半透過平面ミラー１１１の平面に対する角度θ１〜θ６が、一対の平行平面ミラー１１０における光Ｌの進行方向に沿って段階的に大きくなるように設けられてなる。
これによれば、ルーバー１２１〜１２６の先端が視点２に向けられるため、視点２から視認されるルーバー１２１〜１２６の幅を狭くして視認者の視界のうちルーバー１２１〜１２６によって遮られる領域を少なくでき、ルーバー１２１〜１２６を設ける構成であっても良好な視認性を確保することができる。
なお、複数のルーバー１２１〜１２６は、半透過平面ミラー１１１の平面に対する角度θ１〜θ６が、一対の平行平面ミラー１１０における光Ｌの進行方向に沿って徐々に（段階的に１つずつ）大きくなるように設けられてなるものであってもよい（θ１＜θ２＜θ３＜θ４＜θ５＜θ６）。 Further, the plurality of louvers 121 to 126 are provided such that the angles θ1 to θ6 with respect to the plane of the semi-transmissive flat mirror 111 are increased stepwise along the traveling direction of the light L in the pair of parallel flat mirrors 110. .
According to this, since the tips of the louvers 121 to 126 are directed to the viewpoint 2, the width of the louvers 121 to 126 visually recognized from the viewpoint 2 is narrowed so that the area blocked by the louvers 121 to 126 in the viewer's field of view. Even if it is the structure which provides the louvers 121-126, favorable visibility can be ensured.
In addition, the plurality of louvers 121 to 126 have the angles θ1 to θ6 with respect to the plane of the semi-transmissive flat mirror 111 gradually and gradually (one step by step) along the traveling direction of the light L in the pair of parallel flat mirrors 110. (Θ1 <θ2 <θ3 <θ4 <θ5 <θ6).

なお、本発明は上記実施形態及び図面によって限定されるものではない。上記実施形態及び図面に変更（構成要素の削除も含む）を加えることができるのはもちろんである。例えば、ルーバー１２１〜１２６を軸部を介して配置するなどしてルーバー１２１〜１２６の角度を手動などで調整可能に配設してもよい。この場合、全てのルーバー１２１〜１２６を半透過平面ミラー１１１の平面に対して近づけて傾けた状態でルーバー１２１〜１２６によって半透過平面ミラー１１１の平面が覆われるようにすれば、不使用時に半透過平面ミラー１１１にゴミや埃が付着することを防止し、また、傷や破損を防止することができる。また、ルーバー１２１〜１２６を含む遮光部材１２０をシリコーンなどの柔軟性を有する材料によって構成してもよい。これによれば、容易に遮光部材１２０を着脱することができ、遮光部材１２０を外して半透過平面ミラー１１１の汚れを除去しやすく、また、色やデザインにバリエーションを持たせて視認者が好みに応じて交換する際にも利便性が高い。さらに、視認者等が誤って死角補助装置１００に接触する際に緩衝部材としての機能を果たすことができる。また、本実施形態では、一対の平行平面ミラー１１０の間は中空であったが、一対の平行平面ミラー１１０の間に透明な樹脂材料（透光性部材）を充填するなどして中実構造としてもよい。これによって、埃や汚れなどが一対の平行平面ミラー１１０の内面に付着することを防止することができる。   In addition, this invention is not limited by the said embodiment and drawing. It goes without saying that changes (including deletion of components) can be added to the embodiment and the drawings. For example, the louvers 121 to 126 may be disposed via a shaft portion so that the angles of the louvers 121 to 126 can be manually adjusted. In this case, if all the louvers 121 to 126 are inclined close to the plane of the semi-transmissive flat mirror 111 and the planes of the semi-transmissive flat mirror 111 are covered by the louvers 121 to 126, the louvers are partially half-used when not in use. It is possible to prevent dust and dirt from adhering to the transmission flat mirror 111, and to prevent scratches and damage. Further, the light shielding member 120 including the louvers 121 to 126 may be made of a flexible material such as silicone. According to this, the light shielding member 120 can be easily attached and detached, it is easy to remove the dirt from the semi-transmissive flat mirror 111 by removing the light shielding member 120, and there are variations in color and design, which the viewer likes. Convenience is also high when exchanging depending on the situation. Further, when a viewer or the like mistakenly contacts the blind spot assisting device 100, the function as a buffer member can be achieved. In this embodiment, the space between the pair of parallel plane mirrors 110 is hollow, but a solid structure is formed by filling a transparent resin material (translucent member) between the pair of parallel plane mirrors 110. It is good. Thereby, dust and dirt can be prevented from adhering to the inner surfaces of the pair of parallel flat mirrors 110.

本実施形態の死角補助装置１００は、車両１の運転席側から見て右側のフロントピラー５０に配置されるものであったが、左側のフロントピラー６０にも同様の死角補助装置が配置されてもよい。また、車両内の障害物として、フロントピラーの他にもセンターピラーやリアピラーなどに配置され、これらによって遮られる死角領域の像を映す死角補助装置であってもよい。   The blind spot assisting device 100 of the present embodiment is disposed on the right front pillar 50 as viewed from the driver's seat side of the vehicle 1, but a similar blind spot assisting device is also disposed on the left front pillar 60. Also good. Further, as an obstacle in the vehicle, it may be a blind spot assisting device that is arranged on a center pillar, a rear pillar, or the like in addition to the front pillar and displays an image of a blind spot area blocked by these.
