In the following description, a head-up display (HUD) having a combiner as a display unit will be described as an example of the display device.
［全体構造］
　図１は、実施例１に係る表示装置１０の表示動作時（コンバイナ展開時）における斜視図である。また、図２は、表示装置１０の非表示動作時（コンバイナ収納時）表示装置１０は、例えば移動体に搭載される。自動車等に搭載される際、表示装置１０は、のダッシュボード内に収納して搭載される。 [Overall structure]
FIG. 1 is a perspective view of the display device 10 according to the first embodiment during a display operation (when the combiner is unfolded). In FIG. 2, the display device 10 is mounted on, for example, a moving body during the non-display operation of the display device 10 (when the combiner is stored). When mounted on an automobile or the like, the display device 10 is housed and mounted in the dashboard.
　筐体１１は、板状の基部ＢＰ及び当該基部ＢＰから垂直に立ち上がり、互いに対向している長手状でかつ板状の一対の側板部ＳＰを有している。天板１３は、基部ＢＰ及び側板部ＳＰの端部からなるコの字型の側端部の一方に接して設けられている板状の部材である。 The housing 11 has a plate-like base portion BP and a pair of long and plate-like side plate portions SP that stand vertically from the base portion BP and face each other. The top plate 13 is a plate-like member provided in contact with one of the U-shaped side end portions formed by the end portions of the base portion BP and the side plate portion SP.
　以下の説明においては、天板１３の板面Ｓに平行な平面と側板部ＳＰの板面Ｔに平行な平面の交線に沿った方向を表示装置１０の奥行き（前後）方向（Ｘ軸方向）として説明する。また、側板部ＳＰの板面Ｔと垂直な方向を幅方向（Ｙ軸方向）として説明する。また、表示装置１０の前後方向及び幅方向の両方に直交する方向、すなわち天板１３の板面Ｓに垂直な方向を表示装置１０の高さ方向（Ｚ軸方向）として説明する。なお、天板１３から見てコンバイナ筐体１１がある方向を下方、それと反対の方向を上方とする。 In the following description, the direction along the intersection line of the plane parallel to the plate surface S of the top plate 13 and the plane parallel to the plate surface T of the side plate portion SP is defined as the depth (front-rear) direction (X-axis direction) of the display device 10. ). The direction perpendicular to the plate surface T of the side plate portion SP will be described as the width direction (Y-axis direction). A direction perpendicular to both the front-rear direction and the width direction of the display device 10, that is, a direction perpendicular to the plate surface S of the top plate 13 will be described as the height direction (Z-axis direction) of the display device 10. Note that the direction in which the combiner housing 11 is seen from the top plate 13 is the downward direction, and the opposite direction is the upward direction.
　天板１３には、コンバイナ筐体１１の上方に位置している開口１３Ａが設けられている。開口１３Ａは、表示装置１０の幅方向（Ｙ方向）に伸長する長手状の開口である。また、天板１３には、開口１３Ａと奥行き方向（Ｘ方向）において並んでいる開口１３Ｂが設けられている。 The top plate 13 is provided with an opening 13A located above the combiner casing 11. The opening 13 </ b> A is a longitudinal opening that extends in the width direction (Y direction) of the display device 10. In addition, the top plate 13 is provided with an opening 13B aligned with the opening 13A in the depth direction (X direction).
　表示部材としてのイメージコンバイナユニット（以下、コンバイナユニットと称する）１５は、透光性を有する板状のコンバイナ部１５Ａを有する部材である。コンバイナ部１５Ａは、その板面が一方の方向（図中矢印ＰＤ方向）に凸に湾曲している。例えば、コンバイナ部１５Ａは、凹面側から照射光が入射すると凸面側空間領域に虚像を形成するように構成されている。 An image combiner unit (hereinafter referred to as a combiner unit) 15 as a display member is a member having a plate-like combiner portion 15A having translucency. The plate surface of the combiner portion 15A is convexly curved in one direction (the arrow PD direction in the figure). For example, the combiner portion 15A is configured to form a virtual image in the convex-side space region when irradiation light enters from the concave-surface side.
　図１に示すように、表示動作時には、コンバイナユニット１５は、天板１３に形成された開口１３Ａから突出して立ち上がった状態となる。すなわちコンバイナユニット１５は、展開位置にある。また、図２に示すように、コンバイナユニット１５は、非表示動作時には、開口１３Ａを通ってコンバイナ筐体１１内に引き込まれ、コンバイナ筐体１１内に収納される。すなわち、非表示動作時において、コンバイナユニット１５は、２つの側板部ＳＰの間に形成される収納空間内の収納位置にある。 As shown in FIG. 1, during the display operation, the combiner unit 15 protrudes from the opening 13 </ b> A formed in the top plate 13 and rises. That is, the combiner unit 15 is in the deployed position. As shown in FIG. 2, the combiner unit 15 is drawn into the combiner casing 11 through the opening 13 </ b> A and stored in the combiner casing 11 during the non-display operation. That is, during the non-display operation, the combiner unit 15 is in the storage position in the storage space formed between the two side plate portions SP.
　コンバイナユニット１５は、筐体内１１内に形成された通路ＰＷを通り、収納位置と展開位置との間で、コンバイナ部１５Ａの板面（表面）に沿った方向に移動する。この通路ＰＷは、収納位置から展開位置に向かう方向に沿って形成されている。以下、収納位置と展開位置の間における、コンバイナユニット１５が移動する経路をコンバイナユニット１５の移動経路と呼称する。 The combiner unit 15 passes through the passage PW formed in the housing 11 and moves in the direction along the plate surface (surface) of the combiner portion 15A between the storage position and the deployed position. The passage PW is formed along the direction from the storage position toward the deployment position. Hereinafter, a path along which the combiner unit 15 moves between the storage position and the deployed position is referred to as a movement path of the combiner unit 15.
　図３にコンバイナユニット１５の拡大図を示す。図３に示すように、コンバイナ部１５Ａは、保持部１５Ｂによって固定保持されている。保持部１５Ｂの両側面の各々には、側板部ＳＰに形成されているレール（図示せず）に案内されてスライド移動する案内ピンとしてのコンバイナピンＣＰ１及び駆動ピンとしてのコンバイナピンＣＰ２が形成されている。 Fig. 3 shows an enlarged view of the combiner unit 15. As shown in FIG. 3, the combiner portion 15A is fixedly held by a holding portion 15B. A combiner pin CP1 as a guide pin and a combiner pin CP2 as a drive pin are formed on each side surface of the holding portion 15B as a guide pin that is guided by a rail (not shown) formed on the side plate portion SP. ing.
　なお、以下において、Ｘ軸に沿った方向においてコンバイナ部１５Ａの凸に向かう方向（図中矢印ＰＤ方向）を表示装置１０の前方と、その逆を後方として説明する。例えば、表示装置１０を自動車のダッシュボード内に搭載する際は、表示装置１０の前方、すなわち図中矢印ＰＤ方向に自動車のフロントガラスが存在する。また、自動車の搭乗者は表示装置１０の後方側からコンバイナユニット１５を見るものとする。 In the following description, the direction toward the convex of the combiner portion 15A in the direction along the X-axis (the arrow PD direction in the figure) is assumed to be the front of the display device 10 and vice versa. For example, when the display device 10 is mounted in a dashboard of an automobile, the automobile windshield exists in front of the display apparatus 10, that is, in the direction of the arrow PD in the drawing. In addition, it is assumed that the vehicle occupant looks at the combiner unit 15 from the rear side of the display device 10.
　シャッタ１７は、開口１３Ａを開閉するように移動する部材である。図４にシャッタ１７の拡大斜視図を示す。シャッタ１７は、天板１３の板面Ｓと略平行の板面を有する板状のシャッタ板１７Ａと、シャッタ板１７Ａの両端部から垂直に立ち上がり互いに対向している板状の側部１７Ｂを有している。 The shutter 17 is a member that moves to open and close the opening 13A. FIG. 4 shows an enlarged perspective view of the shutter 17. The shutter 17 has a plate-like shutter plate 17A having a plate surface substantially parallel to the plate surface S of the top plate 13, and plate-like side portions 17B that rise vertically from both ends of the shutter plate 17A and face each other. is doing.
　側部１７Ｂには、シャッタ１７を移動させるためのピン（図示せず）が挿入される長手穴である孔部１７Ｈが形成されている。また、側部１７Ｂの各々の互いに対向する面には、側板部ＳＰに形成されているレール（図示せず）に沿って案内されてスライドするシャッタピンＳＨＰが形成されている。 The side portion 17B is formed with a hole portion 17H which is a longitudinal hole into which a pin (not shown) for moving the shutter 17 is inserted. Further, shutter pins SHP that are guided and slid along rails (not shown) formed on the side plate portion SP are formed on the surfaces of the side portions 17B facing each other.
　図１に示すように、コンバイナユニット１５の通路ＰＷの一部となる天板１３の開口部１３Ａは、コンバイナユニット１５の移動経路上に形成されている。表示装置１０の表示動作時、すなわちコンバイナユニット１５が展開位置にある場合には、シャッタ１７は、開口１３Ａからみて前方の開放（待避）位置に待避している。 As shown in FIG. 1, the opening 13 </ b> A of the top plate 13 that is a part of the passage PW of the combiner unit 15 is formed on the moving path of the combiner unit 15. During the display operation of the display device 10, that is, when the combiner unit 15 is in the unfolded position, the shutter 17 is retracted to the forward open (retracted) position as viewed from the opening 13A.
　また、図２に示すように、非表示動作時、すなわちコンバイナユニット１５が収納位置にある場合には、シャッタ１７は開口１３Ａを塞ぐ閉塞位置に位置している。言い換えれば、シャッタ１７は、コンバイナユニット１５の通路（移動経路）ＰＷを閉塞する閉塞位置と当該通路（移動経路）ＰＷ外の位置、すなわち当該通路（移動経路）ＰＷを開放する退避位置との間で移動自在、すなわち移動可能である。従って、シャッタ１７は、コンバイナユニット１５の通路（移動経路）ＰＷを、すなわち開口部としての開口１３Ａを選択的に閉塞可能である。 Further, as shown in FIG. 2, during the non-display operation, that is, when the combiner unit 15 is in the storage position, the shutter 17 is positioned at the closed position that closes the opening 13A. In other words, the shutter 17 is between the closed position that closes the passage (movement path) PW of the combiner unit 15 and the position outside the passage (movement path) PW, that is, the retreat position that opens the passage (movement path) PW. Is movable, that is, movable. Therefore, the shutter 17 can selectively close the passage (movement path) PW of the combiner unit 15, that is, the opening 13A as the opening.
　具体的には、例えば、表示装置１０の電源投入前（自動車のエンジンの始動前、またはイグニションオン前）においては、コンバイナユニット１５がコンバイナ筐体１１内の収納位置に収納されており、シャッタ１７が開口１３Ａを塞ぐ閉塞位置に配される。その後、表示装置１０の電源が投入されると、まずシャッタ１７が開口部１３Ａ全体又はその一部を開放する開放位置に待避し、その後にコンバイナユニット１５が開口１３Ａを通過してせり上がり、展開位置に配置される。 Specifically, for example, before the display device 10 is turned on (before the automobile engine is started or before the ignition is turned on), the combiner unit 15 is stored in the storage position in the combiner casing 11 and the shutter 17 Is disposed at a closed position for closing the opening 13A. After that, when the power of the display device 10 is turned on, the shutter 17 is first retracted to an open position where the entire opening portion 13A or a part thereof is opened, and then the combiner unit 15 rises through the opening 13A and expands. Placed in position.
　図５は、表示動作時、すなわちコンバイナ展開時の表示装置１０の断面斜視図である。光源筐体１９は、コンバイナ筐体の側板部ＳＰの立ち上がり方向の先端部によって形成された開口、すなわち後方に開いた開口１１Ａ及び天板１３の開口１３Ｂを覆うように設けられている。なお、コンバイナ筐体１１、天板１３及び光源筐体１９を含めて筐体としてもよい。 FIG. 5 is a cross-sectional perspective view of the display device 10 during the display operation, that is, when the combiner is unfolded. The light source housing 19 is provided so as to cover the opening formed by the leading end portion of the side plate portion SP of the combiner housing, that is, the opening 11A opened rearward and the opening 13B of the top plate 13. The combiner casing 11, the top plate 13, and the light source casing 19 may be used as a casing.
　光源筐体１９は、光源２１及び光源２１からの照射光を反射する反射鏡等の反射部材２３を収納する角柱状の収納部１９Ａを有している。収納部１９Ａは、開口１３Ｂに面して形成されている。 The light source casing 19 has a prismatic storage portion 19 </ b> A that stores a light source 21 and a reflecting member 23 such as a reflecting mirror that reflects light emitted from the light source 21. The storage portion 19A is formed facing the opening 13B.
　光源２１は、光源筐体１９内に収納されている発光装置である。光源２１は、表示装置１０の後方に照射光ＰＬ（図中矢印）を出射するように配置されている。光源２１は、例えば、外部装置から入力された情報に基づいて投影像を生成する照射光ＰＬを出射する。 The light source 21 is a light emitting device housed in the light source casing 19. The light source 21 is disposed behind the display device 10 so as to emit the irradiation light PL (arrow in the figure). The light source 21 emits irradiation light PL that generates a projection image based on information input from an external device, for example.
　光源２１は、例えば、表示装置１０が搭載されている車両に備えられているナビゲーション装置（図示せず）に接続されている。また、光源２１は、例えば、表示装置が搭載されている車両の位置、速度、移動方向、周辺状況等を検知する検知装置（図示せず）に接続されている。また、光源２１は、例えば、搭載されている車両のインストルメント・パネルに表示される情報を生成する装置（図示せず）に接続されている。すなわち、光源２１は、例えば、これらの装置からの情報に基づいて照射光ＰＬを生成する。 The light source 21 is connected to, for example, a navigation device (not shown) provided in a vehicle on which the display device 10 is mounted. The light source 21 is connected to, for example, a detection device (not shown) that detects the position, speed, moving direction, surrounding situation, and the like of the vehicle on which the display device is mounted. The light source 21 is connected to, for example, a device (not shown) that generates information displayed on the instrument panel of the vehicle on which the light source 21 is mounted. That is, the light source 21 generates the irradiation light PL based on information from these devices, for example.
　反射部材２３は、収納部１９Ａの後方側の側壁部に、光源２１からの照射光ＰＬを反射するように設けられている。図５に示すように、光源２１から出射された照射光ＰＬは反射部材２３で反射され、開口１３Ｂを通ってコンバイナ部１５Ａに到達する。 The reflection member 23 is provided on the side wall portion on the rear side of the storage portion 19A so as to reflect the irradiation light PL from the light source 21. As shown in FIG. 5, the irradiation light PL emitted from the light source 21 is reflected by the reflecting member 23, and reaches the combiner portion 15A through the opening 13B.
　照射光ＰＬは、コンバイナ部１５Ａの後方からコンバイナ部１５Ａの凹面（入射表面、被照射面）に入射する。コンバイナ部１５Ａに入射した照射光ＰＬは、コンバイナ部１５Ａの前方に虚像を形成する。すなわち、表示装置１０が自動車のダッシュボード内に搭載されている場合、照射光ＰＬによって、表示装置１０の前方、すなわち自動車のフロントガラス側に虚像が形成される。
［移動機構］
　次に、コンバイナ筐体１１の側板部ＳＰの構造並びにコンバイナユニット１５及びシャッタ１７の移動機構について説明する。 The irradiation light PL is incident on the concave surface (incident surface, irradiated surface) of the combiner portion 15A from the rear of the combiner portion 15A. The irradiation light PL that has entered the combiner unit 15A forms a virtual image in front of the combiner unit 15A. That is, when the display device 10 is mounted in the dashboard of the automobile, a virtual image is formed in front of the display device 10, that is, on the windshield side of the automobile, by the irradiation light PL.
[Movement mechanism]
Next, the structure of the side plate SP of the combiner housing 11 and the moving mechanism of the combiner unit 15 and the shutter 17 will be described.
　図６は、表示装置１０の分解斜視図である。なお、図６においては、図の簡略化のため、天板１３、光源筐体１９、光源２１、及び反射部材２３を省略する。また、シャッタ１７については分解状態にせずに示している。 FIG. 6 is an exploded perspective view of the display device 10. In FIG. 6, the top plate 13, the light source casing 19, the light source 21, and the reflecting member 23 are omitted for simplification of the drawing. Further, the shutter 17 is shown without being disassembled.
　移動機構は、一対の側板部ＳＰの少なくとも一方に沿って設けられ、表示部材であるコンバイナユニット１５と、シャッタ１７とを移動させる。 The moving mechanism is provided along at least one of the pair of side plate portions SP, and moves the combiner unit 15 that is a display member and the shutter 17.
　駆動源としてのモータＭは、例えば電気モータである。モータＭは、動力伝達機構（図示せず）を介して、駆動シャフトＳＨを回転させるべく接続されている。駆動シャフトＳＨの両端部には、第１のギアとしての駆動ギア３１が形成されている。 The motor M as a drive source is, for example, an electric motor. The motor M is connected to rotate the drive shaft SH via a power transmission mechanism (not shown). A drive gear 31 as a first gear is formed at both ends of the drive shaft SH.
　側板部ＳＰは、最内層から内板ＳＰ１、中板ＳＰ２、外板ＳＰ３からなる３層構造の多層板構造になっている。なお、中板ＳＰ２は、内板ＳＰ１とシャッタの側部１７Ｂとの間に挟まれている。 The side plate portion SP has a multi-layered structure having a three-layer structure including an inner plate SP1, an intermediate plate SP2, and an outer plate SP3 from the innermost layer. The intermediate plate SP2 is sandwiched between the inner plate SP1 and the side portion 17B of the shutter.
　内板ＳＰ１の内側の面、すなわち中板ＳＰ２と反対側の面には、側壁部ＳＰの長手方向に伸長するガイド（案内）溝であるコンバイナレールＣＲ１が形成されている。第３のカム構造としてのコンバイナレールＣＲ１には、コンバイナユニット１５のコンバイナピンＣＰ１が挿入されている。すなわち、コンバイナピンＣＰ１は、コンバイナレールＣＲ１によって案内されて移動する。 A combiner rail CR1, which is a guide groove extending in the longitudinal direction of the side wall SP, is formed on the inner surface of the inner plate SP1, that is, the surface opposite to the middle plate SP2. The combiner pin CP1 of the combiner unit 15 is inserted into the combiner rail CR1 as the third cam structure. That is, the combiner pin CP1 moves while being guided by the combiner rail CR1.
　また、内板ＳＰ１には、コンバイナレールＣＲ１の前方において、コンバイナレールＣＲ１と略平行に伸長するコンバイナレールＣＲ２が形成されている。第１のカム構造としてのコンバイナレールＣＲ２は、内板ＳＰ１を貫通しているガイド穴である。コンバイナレールＣＲ２には、コンバイナユニット１５のコンバイナピンＣＰ２が挿入されている。すなわち、コンバイナピンＣＰ２とコンバイナレールＣＲ２とが係合している。コンバイナピンＣＰ２は、コンバイナレールＣＲ２を貫通して外方に突出している。すなわち、コンバイナピンＣＰ２は、コンバイナレールＣＲ２によって案内されて移動する。 Further, the inner plate SP1 is formed with a combiner rail CR2 that extends substantially in parallel with the combiner rail CR1 in front of the combiner rail CR1. The combiner rail CR2 as the first cam structure is a guide hole penetrating the inner plate SP1. The combiner pin CP2 of the combiner unit 15 is inserted into the combiner rail CR2. That is, the combiner pin CP2 and the combiner rail CR2 are engaged. The combiner pin CP2 protrudes outward through the combiner rail CR2. That is, the combiner pin CP2 moves while being guided by the combiner rail CR2.
　なお、コンバイナレールＣＲ２は、伸長方向の中間部においてコンバイナレールＣＲ１と平行に伸長しているが、両端部領域において、コンバイナレールＣＲ１からの距離が変化するように形成されている。すなわち、コンバイナレールＣＲ２は、両端部領域において、コンバイナレールＣＲ１の伸長方向と角度を持って伸長している。 The combiner rail CR2 extends in parallel with the combiner rail CR1 at the intermediate portion in the extending direction, but is formed such that the distance from the combiner rail CR1 changes in both end regions. That is, the combiner rail CR2 extends at an angle with the extending direction of the combiner rail CR1 in both end regions.
　また、内板ＳＰ１の外側には、側壁部ＳＰの長手方向に伸長し、互いに平行なガイド溝であるスライドレールＳＲ１及びＳＲ２が形成されている。 Further, slide rails SR1 and SR2 which are guide grooves extending in the longitudinal direction of the side wall portion SP and parallel to each other are formed on the outer side of the inner plate SP1.
　また、内板ＳＰ１には、駆動シャフトＳＨを支持する開口部（図示せず）が形成されている。駆動シャフトＳＨの端部は内板ＳＰ１の開口部を通り抜けて内板ＳＰ１の外側に突出している。すなわち、駆動ギア３１は、内板ＳＰ１の外側に配されている。 Further, an opening (not shown) for supporting the drive shaft SH is formed in the inner plate SP1. The end of the drive shaft SH passes through the opening of the inner plate SP1 and protrudes outside the inner plate SP1. That is, the drive gear 31 is disposed outside the inner plate SP1.
　シャッタ駆動部材としてのレバー部材３２は、鉤型の板状部材である。レバー部材３２は、シャッタ１７の側部１７Ｂとともに中板ＳＰ２を挟み込んでいる。レバー部材３２は、鉤型の折曲部近傍に駆動シャフトＳＨが貫通している孔部（図示せず）を有している。 The lever member 32 as a shutter driving member is a bowl-shaped plate member. The lever member 32 sandwiches the intermediate plate SP2 together with the side portion 17B of the shutter 17. The lever member 32 has a hole (not shown) through which the drive shaft SH passes in the vicinity of the saddle-shaped bent portion.
　すなわち、レバー部材３２は、駆動シャフトＳＨに支持され、駆動シャフトＳＨを軸に回動可能となっている。なお、レバー部材３２は、バネ等の付勢部材（図示せず）によって、駆動シャフトＳＨの回転軸を中心に反時計回り方向（図中矢印方向）に付勢されている。すなわち、レバー部材３２は、表示装置１０の前方に倒れる方向に向かって付勢されている。 That is, the lever member 32 is supported by the drive shaft SH and is rotatable about the drive shaft SH. The lever member 32 is urged counterclockwise (arrow direction in the figure) about the rotation axis of the drive shaft SH by an urging member (not shown) such as a spring. That is, the lever member 32 is urged toward the direction of falling forward of the display device 10.
　また、レバー部材３２には、駆動シャフトＳＨが貫通している孔部（図示せず）から近接している端部にレバーピンＬＰ１が形成されている。また、レバーピンＬＰ１が形成されている端部と反対側の端部には、シャッタ１７の孔部１７Ｈに挿入されているレバーピンＬＰ２が形成されている。 Further, the lever member LP1 is formed on the lever member 32 at an end portion close to a hole portion (not shown) through which the drive shaft SH passes. A lever pin LP2 inserted into the hole 17H of the shutter 17 is formed at the end opposite to the end where the lever pin LP1 is formed.
　中板ＳＰ２には、表示装置１０の前方から順に互いに平行に並んで形成されているガイド穴であるスライドレールＳＲ３、ＳＲ４及びＳＲ５が形成されている。また、中板ＳＰ２には、表示装置１０の前後方向に伸長しているシャッタレールＳＨＲが形成されている。シャッタレールＳＨＲには、シャッタ１７のシャッタピンＳＨＰ（図４参照）が挿入されている。すなわち、シャッタピンＳＨＰは、シャッタレールＳＨＲに沿って案内されて移動する。 In the middle plate SP2, slide rails SR3, SR4, and SR5, which are guide holes formed in parallel with each other in order from the front of the display device 10, are formed. Further, a shutter rail SHR extending in the front-rear direction of the display device 10 is formed on the intermediate plate SP2. The shutter pin SHP (see FIG. 4) of the shutter 17 is inserted into the shutter rail SHR. That is, the shutter pin SHP is guided and moved along the shutter rail SHR.
　また、中板ＳＰ２には、孔部であるレバーレールＬＲが形成されている。レバーレールＬＲは、中板ＳＰ２を貫通している。レバーレールＬＲは、表示装置１０の幅方向（Ｙ軸方向）に沿った方向から見て駆動シャフトＳＨの回転軸を中心とした円弧に沿って形成されている。レバーレールＬＲには、レバーピンＬＰ２が挿入されている。また、中板ＳＰ２には、スライド移動部材としての第１のスライド部材３３及び駆動部材としての第２のスライド部材３４が取り付けられている。 Also, a lever rail LR that is a hole is formed in the middle plate SP2. The lever rail LR passes through the intermediate plate SP2. The lever rail LR is formed along an arc centered on the rotation axis of the drive shaft SH when viewed from the direction along the width direction (Y-axis direction) of the display device 10. A lever pin LP2 is inserted into the lever rail LR. A first slide member 33 as a slide moving member and a second slide member 34 as a drive member are attached to the middle plate SP2.
　第１のスライド部材３３は、板材からなっている。第１のスライド部材３３には、第１のスライド部材を貫通して第１のスライド部材３３の主面に垂直な両方向に突出している２つのピン３３Ｐが設けられている。２つのピン３３Ｐの各々は、中板ＳＰ２に対して突出している部分（図示せず）が、スライドレールＳＲ３に挿入されている。すなわち２つのピン３３Ｐの各々は、スライドレールＳＲ３に案内されて移動する。従って、第１のスライド部材３３は、スライドレールＳＲ３に沿って移動可能に形成されている。 The first slide member 33 is made of a plate material. The first slide member 33 is provided with two pins 33P that penetrate the first slide member and project in both directions perpendicular to the main surface of the first slide member 33. In each of the two pins 33P, a portion (not shown) protruding from the middle plate SP2 is inserted into the slide rail SR3. That is, each of the two pins 33P moves while being guided by the slide rail SR3. Accordingly, the first slide member 33 is formed to be movable along the slide rail SR3.
　第１のラックギアとしての第１のラックＬ１（図７も参照）は、第１のスライド部材３３のスライドレールＳＲ３の伸長方向に沿った一辺に形成されているラックギアである。第１のラックＬ１は、駆動ギア３１と噛み合っている。伝達部材及び第２のギアとしてのピニオンギア３５は、第１のラックＬ１が形成されている辺とは反対側の辺に沿った角部に設けられている。ピニオンギア３５は、第１のスライド部材３３と、例えばピン接合されており、第１のスライド部材３３の一点を支点にして回転自在になっている。すなわち、ピニオンギア３５は、第１のスライド部材３３と係合している。 The first rack L1 (see also FIG. 7) as the first rack gear is a rack gear formed on one side along the extending direction of the slide rail SR3 of the first slide member 33. The first rack L <b> 1 meshes with the drive gear 31. The transmission member and the pinion gear 35 as the second gear are provided at corners along the side opposite to the side where the first rack L1 is formed. The pinion gear 35 is, for example, pin-joined with the first slide member 33 and is rotatable about one point of the first slide member 33 as a fulcrum. That is, the pinion gear 35 is engaged with the first slide member 33.
　第２のスライド部材３４は、中板ＳＰ２の外側に位置している外側プレート３４Ａ及び中板ＳＰ２の内側に位置している内側プレート３４Ｂを有している。第１のプレートとしての外側プレート３４Ａ及び第２のプレートとしての内側プレート３４Ｂは、スライドレールＳＲ４及びスライドレールＳＲ５を通り抜けている２つのピン３４Ｐによって互いに結合されている。すなわち、第２のスライド部材３４は、スライドレールＳＲ４、ＳＲ５に沿って移動可能となっている。ピン３４Ｐは、外側プレート３４Ａを貫通して外方に突出している。 The second slide member 34 has an outer plate 34A located outside the middle plate SP2 and an inner plate 34B located inside the middle plate SP2. The outer plate 34A as the first plate and the inner plate 34B as the second plate are coupled to each other by two pins 34P passing through the slide rail SR4 and the slide rail SR5. That is, the second slide member 34 is movable along the slide rails SR4 and SR5. The pin 34P protrudes outward through the outer plate 34A.
　なお、外側プレート３４Ａと内側プレート３４Ｂとは、上下方向（Ｚ方向）において内側プレート３４Ｂの上端部が外側プレート３４Ａの上端部と同じかそれより低い位置に来るように結合されている。 The outer plate 34A and the inner plate 34B are coupled so that the upper end of the inner plate 34B is at the same level as or lower than the upper end of the outer plate 34A in the vertical direction (Z direction).
　外側プレート３４Ａは、スライドレールＳＲ４の伸長方向に沿っておりかつ第１のスライド部材３３に面した辺に第２のラックギアとしての第２のラックＬ２が形成されている。第２のラックＬ２は、ラックギアであり、ピニオンギア３５と噛み合っている。 The outer plate 34A is formed with a second rack L2 as a second rack gear along the extending direction of the slide rail SR4 and on the side facing the first slide member 33. The second rack L2 is a rack gear and meshes with the pinion gear 35.
　内側プレート３４Ｂは、鉤型形状を有している板材である。すなわち、内側プレート３４Ｂは、表示装置１０の幅方向に沿った方向、すなわち側板部ＳＰの板面Ｔと垂直な方向から見て外側プレート３４Ａから突出している拡張部Ｅを有する。すなわち、拡張部Ｅは、内側プレート３４Ｂから第２のラックＬ２側に突出して設けられている。さらに言い換えれば、拡張部Ｅは、第２のラックＬ２の歯先が向いている方向に向かって突出している。拡張部Ｅには、コンバイナレールＣＲ２と重なる位置に形成されているガイド穴３４Ｈが形成されている。ガイド穴３４Ｈは、コンバイナレールＣＲ２と角度を持って伸長している。 The inner plate 34B is a plate material having a saddle shape. That is, the inner plate 34B has the extended portion E that protrudes from the outer plate 34A when viewed from the direction along the width direction of the display device 10, that is, the direction perpendicular to the plate surface T of the side plate portion SP. That is, the extended portion E is provided so as to protrude from the inner plate 34B to the second rack L2 side. In other words, the expansion part E protrudes in the direction in which the tooth tip of the second rack L2 faces. The expansion portion E is formed with a guide hole 34H formed at a position overlapping the combiner rail CR2. The guide hole 34H extends at an angle with the combiner rail CR2.
　第２のカム構造としてのガイド穴３４Ｈには、コンバイナユニット１５のコンバイナピンＣＰ２が挿入されている。言い換えれば、コンバイナピンＣＰ２とガイド穴３４Ｈとが係合している。すなわち、コンバイナピンＣＰ２は、コンバイナレールＣＲ２及びガイド穴３４Ｈによって拘束されて第２のスライド部材３４の移動に従って移動する。言い換えれば、第２のスライド部材３４の移動中において、内板ＳＰ１の板面に垂直な方向から見て、ガイド穴３４ＨはコンバイナレールＣＲ２と立体交差している。 The combiner pin CP2 of the combiner unit 15 is inserted into the guide hole 34H as the second cam structure. In other words, the combiner pin CP2 is engaged with the guide hole 34H. That is, the combiner pin CP2 is restrained by the combiner rail CR2 and the guide hole 34H and moves according to the movement of the second slide member 34. In other words, during the movement of the second slide member 34, the guide hole 34H three-dimensionally intersects with the combiner rail CR2 when viewed from the direction perpendicular to the plate surface of the inner plate SP1.
　また、内側プレート３４Ｂの拡張部Ｅは、第２のスライド部材３４が下方に移動した際に、レバーピンＬＰ１に接触してレバーピンＬＰ１を下方に押し下げる。これにより、レバー部材３２は、時計回り方向に回動する。すなわち、表示装置１０の移動機構によれば、第２のスライド部材３４の移動によって、コンバイナユニット１５及びシャッタ１７の両方を移動させることが可能である。言い換えれば、シャッタ１７は、移動機構によって（移動機構に連動して）移動する。 Also, when the second slide member 34 moves downward, the extended portion E of the inner plate 34B contacts the lever pin LP1 and pushes the lever pin LP1 downward. As a result, the lever member 32 rotates in the clockwise direction. That is, according to the moving mechanism of the display device 10, it is possible to move both the combiner unit 15 and the shutter 17 by the movement of the second slide member 34. In other words, the shutter 17 is moved by the moving mechanism (in conjunction with the moving mechanism).
　なお、内側プレート３４Ｂには、内板ＳＰ１に向かって突出している２つのピン（図示せず）が形成されている。この２つのピンの各々は、内板ＳＰ１のスライドレールＳＲ１及びＳＲ２にそれぞれ挿入されている。 The inner plate 34B is formed with two pins (not shown) protruding toward the inner plate SP1. Each of these two pins is inserted into the slide rails SR1 and SR2 of the inner plate SP1.
　外板ＳＰ３には、中板ＳＰ２のスライドレールＳＲ３、ＳＲ４、ＳＲ５と対向する位置にそれぞれガイド溝であるスライドレールＳＲ６、ＳＲ７、ＳＲ８が形成されている。スライドレールＳＲ６には、第１のスライド部材３３のピン３３Ｐが挿入されている。また、スライドレールＳＲ７及びＳＲ８のそれぞれには、第２のスライド部材３４のスライドピン３４Ｐが挿入されている。 The outer plate SP3 is formed with slide rails SR6, SR7, SR8, which are guide grooves, at positions facing the slide rails SR3, SR4, SR5 of the middle plate SP2. A pin 33P of the first slide member 33 is inserted into the slide rail SR6. Further, the slide pins 34P of the second slide member 34 are inserted into the slide rails SR7 and SR8, respectively.
　外板ＳＰ３の内側、すなわち中板ＳＰ２に向いている面には、第３のラックギアとしての第３のラックＬ３が形成されている。第３のラックＬ３は、ラックギアでありピニオンギア３５と噛み合っている。 A third rack L3 as a third rack gear is formed on the inner side of the outer plate SP3, that is, the surface facing the middle plate SP2. The third rack L3 is a rack gear and meshes with the pinion gear 35.
　すなわち、表示装置１０においては、まず駆動モータＭが駆動し、駆動シャフトＳＨ及び駆動ギア３１が回転する。駆動ギア３１が回転すると第１のスライド部材３３がスライドレールＳＲ３に沿った方向にスライド移動する。第１のスライド部材３３がスライド移動すると、ピニオンギア３５が第３のラックＬ３によって回転する。 That is, in the display device 10, the drive motor M is first driven, and the drive shaft SH and the drive gear 31 are rotated. When the drive gear 31 rotates, the first slide member 33 slides in the direction along the slide rail SR3. When the first slide member 33 slides, the pinion gear 35 is rotated by the third rack L3.
　言い換えれば、第１のスライド部材３３が上方または下方にスライド移動する際、ピニオンギア３５は、ラックＬ３に接して転がりながら回転する。すなわち、ピニオンギア３５は、第１のスライド部材３３の移動に従って、回転軸が移動、具体的には、例えば並進移動しながら回転する。 In other words, when the first slide member 33 slides upward or downward, the pinion gear 35 rotates while rolling in contact with the rack L3. That is, the pinion gear 35 rotates while the rotation shaft moves, specifically, for example, translates in accordance with the movement of the first slide member 33.
　上述したように、第２のスライド部材３４の第２のラックＬ２はピニオンギア３５と噛み合っている。そのため、第２のスライド部材３４は、第１のスライド部材３３のスライド移動時に第１のスライド部材３３の移動量（ピニオンギア３５の回転軸の並進移動分）と、ピニオンギア３５の回転によって伝達される移動量を加えた移動量で移動する。すなわち、第２のスライド部材３４は、第１のスライド部材３３の並進移動量の２倍の移動量で並進移動することになる。 As described above, the second rack L2 of the second slide member 34 meshes with the pinion gear 35. Therefore, the second slide member 34 is transmitted by the movement amount of the first slide member 33 (the amount of translational movement of the rotation shaft of the pinion gear 35) and the rotation of the pinion gear 35 when the first slide member 33 slides. It moves with the amount of movement added to the amount of movement that is done. That is, the second slide member 34 translates with a movement amount that is twice the translational movement amount of the first slide member 33.
　すなわち、第１のスライド部材３３、ピニオンギア３５、外板ＳＰ３の第３のラックＬ３、及び第２のスライド部材３４によって、移動量（ストローク）の倍化機構（倍ストローク機構）が形成されている。 That is, the first slide member 33, the pinion gear 35, the third rack L3 of the outer plate SP3, and the second slide member 34 form a movement amount (stroke) doubling mechanism (double stroke mechanism). Yes.
　上述のように、本実施例の移動機構は、スライド移動部材としての第１のスライド部材３３と、表示部材としてのコンバイナユニット１５と係合し第１のスライド部材３３の移動に伴って移動する駆動部材としての第２のスライド部材３４と、第２のスライド部材３４及びシャッタ１７に係合し、第１のスライド部材３３の移動に伴って移動する第２のスライド部材３４の移動に応じてシャッタ１７を移動させるシャッタ駆動部材としてのレバー部材３２と、を備える。 As described above, the moving mechanism of the present embodiment engages with the first slide member 33 as the slide moving member and the combiner unit 15 as the display member, and moves with the movement of the first slide member 33. In accordance with the movement of the second slide member 34 as the drive member, the second slide member 34 that engages with the second slide member 34 and the shutter 17 and moves with the movement of the first slide member 33. And a lever member 32 as a shutter driving member for moving the shutter 17.
　また本実施例の移動機構は、駆動源としてのモータＭによって回転する第１のギアとしての駆動ギア３１を有し、第１のスライド部材３３は、駆動ギア３１に噛み合う第１のラックギアとしての第１のラックＬ１を有し、第１のスライド部材３３は、第１のスライド部材３３の一点を支点にして回転する第２のギアとしてのピニオンギア３５を有し、第２のスライド部材３４は、ピニオンギア３５と噛み合う第２のラックギアとしての第２のラックＬ２を有し、一対の側板部ＳＰの少なくとも一方は、ピニオンギア３５と噛み合う第３のラックギアとしての第３のラックＬ３を有する。 Further, the moving mechanism of the present embodiment has a drive gear 31 as a first gear that is rotated by a motor M as a drive source, and the first slide member 33 is a first rack gear that meshes with the drive gear 31. The first slide member 33 includes a first rack L1, and the first slide member 33 includes a pinion gear 35 as a second gear that rotates with one point of the first slide member 33 as a fulcrum, and the second slide member 34. Has a second rack L2 as a second rack gear meshing with the pinion gear 35, and at least one of the pair of side plate portions SP has a third rack L3 as a third rack gear meshing with the pinion gear 35. .
　本実施例においては、第２のスライド部材３４の移動量が第１のスライド部材３３の移動量が２倍になるとしたが、第１のスライド部材３３の移動量に対する第２のスライド部材３４の移動量を例えば１．５倍や３倍など自在に変更することが可能である。例えば、ピニオンギアを多段ギアにして、各々のギアを第２のラックＬ２または第３のラックＬ３に噛み合わせることによって、第２のスライド部材３４の移動量を調整可能である。 In this embodiment, the amount of movement of the second slide member 34 is twice that of the first slide member 33, but the amount of movement of the second slide member 34 relative to the amount of movement of the first slide member 33 is assumed. It is possible to freely change the movement amount, for example, 1.5 times or 3 times. For example, the movement amount of the second slide member 34 can be adjusted by making the pinion gear a multistage gear and meshing each gear with the second rack L2 or the third rack L3.
　また、本実施例においては、上述のように第２のスライド部材が二重構造になっている。従って、第１のスライド部材３３の移動領域と、コンバイナレールＣＲ２の形成領域、すなわちコンバイナピンＣＰ２を重ねて配置することができる。このようにすることで、表示装置１０の前後方向（Ｘ方向）において移動機構をコンパクトにすることが可能である。 In the present embodiment, the second slide member has a double structure as described above. Accordingly, the moving region of the first slide member 33 and the region where the combiner rail CR2 is formed, that is, the combiner pin CP2 can be arranged in an overlapping manner. By doing in this way, it is possible to make the moving mechanism compact in the front-rear direction (X direction) of the display device 10.
　なお、上記説明した移動機構は、両方の側板部ＳＰに形成されている。
［非動作状態から動作状態への遷移動作］
　次に、図７、図８及び図９を参照して非動作状態から動作状態への遷移について説明する。図７は、非動作状態における表示装置１０の側面図である。なお、図７においては、図の簡略化のため、天板１３、光源筐体１９、光源２１、及び反射部材２３を省略する。 The moving mechanism described above is formed on both side plate portions SP.
[Transition from non-operational state to operational state]
Next, the transition from the non-operating state to the operating state will be described with reference to FIGS. FIG. 7 is a side view of the display device 10 in a non-operating state. In FIG. 7, the top plate 13, the light source casing 19, the light source 21, and the reflecting member 23 are omitted for simplification of the drawing.
　また、図７乃至図９においては、中板ＳＰ２及び外板ＳＰ３を省略している。なお、中板ＳＰ２に形成されているシャッタレールＳＨＲ及びレバーレールＬＲについては、破線で示している。また、第２のスライド部材３４の内側プレート３４Ｂについても、破線で示している。 7 to 9, the middle plate SP2 and the outer plate SP3 are omitted. The shutter rail SHR and lever rail LR formed on the intermediate plate SP2 are indicated by broken lines. The inner plate 34B of the second slide member 34 is also indicated by a broken line.
　非動作状態の際には、第１のスライド部材３３及び第２のスライド部材３４は、それぞれスライドレールＳＲ１及びスライドレールＳＲ２に沿った最下位置にある。この際、コンバイナピンＣＰ１、ＣＰ２もコンバイナレールＣＲ１、ＣＲ２の最下位置にある。すなわち、コンバイナユニット１５は、収納位置にある。 In the non-operating state, the first slide member 33 and the second slide member 34 are at the lowest positions along the slide rail SR1 and the slide rail SR2, respectively. At this time, the combiner pins CP1 and CP2 are also at the lowest position of the combiner rails CR1 and CR2. That is, the combiner unit 15 is in the storage position.
　また、内側プレート３４Ｂの拡張部Ｅ（図６参照）は、レバー部材３２のレバーピンＬＰ１に接して、レバーピンＬＰ１を下方に押し下げている。これにより、レバー部材３２は、付勢に逆らって時計回りに回動し、シャッタ１７が閉塞位置に移動する。 Further, the extended portion E (see FIG. 6) of the inner plate 34B is in contact with the lever pin LP1 of the lever member 32 and pushes the lever pin LP1 downward. As a result, the lever member 32 rotates clockwise against the bias, and the shutter 17 moves to the closed position.
　この状態からモータＭ（図示せず）が駆動して駆動ギア３１が反時計回りに回転すると、第１のスライド部材３３が上方にスライド移動する。第１のスライド部材３３が上方に移動すると、拡張部ＥがレバーピンＬＰ１から離間し、レバー部材３２が反時計回りに回動する。レバー部材３２が回動すると、シャッタ１７は、開口１３Ａを塞ぐ閉塞位置から開放位置にスライド移動する（図８参照）。 When the motor M (not shown) is driven from this state and the drive gear 31 rotates counterclockwise, the first slide member 33 slides upward. When the first slide member 33 moves upward, the extended portion E is separated from the lever pin LP1, and the lever member 32 rotates counterclockwise. When the lever member 32 rotates, the shutter 17 slides from the closed position that closes the opening 13A to the open position (see FIG. 8).
　また、第１のスライド部材３３が上方に移動すると、第２のスライド部材３４も上方に移動する。第２のスライド部材３４が上方に移動すると、コンバイナピンＣＰ２がコンバイナレールＣＲ２に沿って上方に移動する。コンバイナレールＣＲ２は、下部の領域Ｒ１（以下、領域Ｒ１－Ｒ４については、図７及び図８参照）において、コンバイナレールＣＲ１に近づくように形成されている。従って、コンバイナピンＣＰ２に対してコンバイナピンＣＰ１が相対的に上方に移動する。これにより、コンバイナユニット１５が最初の状態からやや前方に傾きつつ上昇していく。 Further, when the first slide member 33 moves upward, the second slide member 34 also moves upward. When the second slide member 34 moves upward, the combiner pin CP2 moves upward along the combiner rail CR2. The combiner rail CR2 is formed so as to approach the combiner rail CR1 in the lower region R1 (hereinafter, refer to FIGS. 7 and 8 for the region R1-R4). Therefore, the combiner pin CP1 moves relatively upward with respect to the combiner pin CP2. As a result, the combiner unit 15 rises while tilting slightly forward from the initial state.
　図８は、非動作状態から動作状態への遷移途中の表示装置１０の側面図である。第１のスライド部材３３がさらに上昇していくと、第２のスライド部材３４もさらに上昇していく。第２のスライド部材３４の上昇につれて、コンバイナピンＣＰ１もさらに上昇する。 FIG. 8 is a side view of the display device 10 during the transition from the non-operating state to the operating state. As the first slide member 33 is further raised, the second slide member 34 is further raised. As the second slide member 34 is raised, the combiner pin CP1 is further raised.
　コンバイナユニット１５は、コンバイナピンＣＰ２が、コンバイナレールＣＲ２がコンバイナレールＣＲ１に近づく領域である領域Ｒ１を通過すると、並進移動を開始する。すなわち、コンバイナピンＣＰ２が、コンバイナレールＣＲ１、ＣＲ２が平行になる領域Ｒ２に達すると、コンバイナユニット１５は並進移動上昇を開始する。この際、コンバイナユニット１５は、基部ＢＰ（図１参照）の板面に沿って移動する。 The combiner unit 15 starts translational movement when the combiner pin CP2 passes through the region R1, which is a region where the combiner rail CR2 approaches the combiner rail CR1. That is, when the combiner pin CP2 reaches the region R2 where the combiner rails CR1 and CR2 are parallel to each other, the combiner unit 15 starts to rise in translation. At this time, the combiner unit 15 moves along the plate surface of the base BP (see FIG. 1).
　コンバイナピンＣＰ２が上昇し、コンバイナレールＣＲ２がコンバイナレールＣＲ１に近づく領域であるＲ３に達すると、コンバイナピンＣＰ２に対してコンバイナピンＣＰ１が相対的に上方に移動する。すなわち、コンバイナユニット１５は、さらに前方に傾きつつ上昇していく。 When the combiner pin CP2 rises and the combiner rail CR2 reaches R3, which is a region approaching the combiner rail CR1, the combiner pin CP1 moves relatively upward with respect to the combiner pin CP2. That is, the combiner unit 15 rises while tilting further forward.
　コンバイナピンＣＰ２がさらに上昇し、コンバイナレールＣＲ２がコンバイナレールＣＲ１から離間する領域であるＲ４に達すると、コンバイナピンＣＰ１は、コンバイナレールＣＲ１の最上部に達する。すなわち、コンバイナユニット１５が最上位置に達する。そして、コンバイナピンＣＰ２に対してコンバイナピンＣＰ１が相対的に下方に移動する。すなわち、コンバイナユニット１５は、後方に傾いていく。 When the combiner pin CP2 further rises and the combiner rail CR2 reaches R4, which is a region separated from the combiner rail CR1, the combiner pin CP1 reaches the top of the combiner rail CR1. That is, the combiner unit 15 reaches the uppermost position. And combiner pin CP1 moves below relatively with respect to combiner pin CP2. That is, the combiner unit 15 is inclined backward.
　図９は、動作状態における表示装置１０の側面図である。図９のように、コンバイナピンＣＰ２がコンバイナレールＣＲ２の端部に達している。上述のように、外側プレート３４Ａと内側プレート３４Ｂとは、上下方向（Ｚ方向）において内側プレート３４Ｂの上端部が外側プレート３４Ａの上端部と同じかそれより低い位置に来るように結合されている。従って、コンバイナピンＣＰ２、ひいては第２のスライド部材３４が最上点に移動した際にも、内側プレート３４Ｂが天板１３よりも上方に突出することはない。 FIG. 9 is a side view of the display device 10 in the operating state. As shown in FIG. 9, the combiner pin CP2 reaches the end of the combiner rail CR2. As described above, the outer plate 34A and the inner plate 34B are coupled so that the upper end of the inner plate 34B is at the same level or lower than the upper end of the outer plate 34A in the vertical direction (Z direction). . Therefore, even when the combiner pin CP2 and, by extension, the second slide member 34 moves to the uppermost point, the inner plate 34B does not protrude above the top plate 13.
　上述のように、コンバイナユニット１５は、収納位置と展開位置との間で、収納位置におけるコンバイナ部１５Ａの板面に沿った方向に移動する。また、第１のスライド部材３３及び第２のスライド部材３４は、コンバイナユニット１５の通路（移動経路）ＰＷに沿って移動する。 As described above, the combiner unit 15 moves between the storage position and the deployed position in a direction along the plate surface of the combiner portion 15A at the storage position. Further, the first slide member 33 and the second slide member 34 move along the path (movement path) PW of the combiner unit 15.
　上述のように、コンバイナユニット１５が最上位置に達した後に、コンバイナピンＣＰ２がコンバイナレールＣＲ２の領域Ｒ４を移動することで、コンバイナユニット１５の傾きが変化する。すなわち、第２のスライド部材３４を移動させて、コンバイナピンＣＰ２を領域Ｒ４内で移動させることで、コンバイナユニット１５の傾きを調整することが可能である。 As described above, after the combiner unit 15 reaches the uppermost position, the combiner pin CP2 moves in the region R4 of the combiner rail CR2, so that the inclination of the combiner unit 15 changes. That is, the tilt of the combiner unit 15 can be adjusted by moving the second slide member 34 and moving the combiner pin CP2 within the region R4.
　本実施例の表示装置１０では、第１のスライド部材３３、ピニオンギア３５、外板ＳＰ３の第３のラックＬ３、及び第２のスライド部材３４によって構成される移動量倍化機構によって、コンバイナユニット１５を並進移動させる。 In the display device 10 according to the present embodiment, the combiner unit is configured by the movement amount doubling mechanism including the first slide member 33, the pinion gear 35, the third rack L3 of the outer plate SP3, and the second slide member 34. 15 is translated.
　また、全ての移動機構が１つのモータＭによって駆動される。さらに移動機構の要素のスライド移動のみで、コンバイナユニット１５の移動が達成され、移動機構をコンパクトにすることができる。これらのことにより、コンバイナ筐体１１がコンパクト化される。　　　 Also, all the moving mechanisms are driven by one motor M. Furthermore, the movement of the combiner unit 15 is achieved only by sliding the elements of the moving mechanism, and the moving mechanism can be made compact. By these things, the combiner housing | casing 11 is compactized. *
　また、本実施例の表示装置１０においては、上述のように第２のスライド部材が二重構造になっている。従って、第１のスライド部材３３の移動領域と、コンバイナレールＣＲ２の形成領域、すなわちコンバイナピンＣＰ２を重ねて配置することができる。このようにすることで、表示装置１０の前後方向（Ｘ方向）において移動機構をコンパクトにすることが可能である。 Moreover, in the display device 10 of the present embodiment, the second slide member has a double structure as described above. Accordingly, the moving region of the first slide member 33 and the region where the combiner rail CR2 is formed, that is, the combiner pin CP2 can be arranged in an overlapping manner. By doing in this way, it is possible to make the moving mechanism compact in the front-rear direction (X direction) of the display device 10.
　従って、例えば、表示装置１０を車両に搭載する際のスペースの制約を減らすことが可能である。 Therefore, for example, it is possible to reduce space restrictions when the display device 10 is mounted on a vehicle.
　また、本実施例の表示装置１０の移動機構によれば、第２のスライド部材３４がスライドすることによって、コンバイナユニット１５及びシャッタ１７の両方を移動させることが可能である。すなわち、移動機構の単純化及び部品点数の低減を達成することが可能である。また、移動機構をコンバイナ筐体１１の側板部ＳＰに設ける（集約する）ことで、側板部ＳＰ間の空間を有効活用することができる。 Further, according to the moving mechanism of the display device 10 of the present embodiment, it is possible to move both the combiner unit 15 and the shutter 17 by sliding the second slide member 34. That is, it is possible to achieve a simplified moving mechanism and a reduced number of parts. Moreover, the space between the side plate portions SP can be effectively used by providing (aggregating) the moving mechanism in the side plate portion SP of the combiner casing 11.
　また、本実施例の表示装置１０においては、コンバイナレールＣＲ１、ＣＲ２の距離を変化させることによって、コンバイナユニット１５の角度を適切に変化させつつ並進移動させることが可能である。すなわち、最小の通路（移動経路の空間）を実現し、コンバイナ筐体１１、ひいては表示装置１０のコンパクト化が可能である。 Further, in the display device 10 of the present embodiment, it is possible to perform translation while changing the angle of the combiner unit 15 appropriately by changing the distance between the combiner rails CR1 and CR2. That is, the minimum passage (movement path space) can be realized, and the combiner casing 11 and thus the display device 10 can be made compact.
　また、本実施例の表示装置１０においては、第２のスライド部材３４を外側プレート３４Ａと内側プレート３４Ｂの二層構造で形成した。これにより、第２のスライド部材３４を移動させるための第２のラックＬ２とコンバイナピンＣＰ２を拘束するガイド穴３４Ｈを第２のスライド部材３４の同一側に形成することが可能である。これにより、移動機構のさらなる省スペース化が可能である。 Further, in the display device 10 of the present embodiment, the second slide member 34 is formed with a two-layer structure of the outer plate 34A and the inner plate 34B. Thereby, it is possible to form a guide hole 34H for restraining the second rack L2 and the combiner pin CP2 for moving the second slide member 34 on the same side of the second slide member 34. Thereby, further space saving of the moving mechanism is possible.
　また、内板ＳＰ１の板面に垂直な方向から見て、第１のスライド部材３３とガイド穴３４Ｈとが重なって位置することが可能である。従って、上記実施例のように、第１のスライド部材３３、ピニオンギア３５及び第２のスライド部材３４からなる倍化機構を用いる構成等を用いる場合でも、移動機構の省スペース化が可能である。 Also, the first slide member 33 and the guide hole 34H can be positioned so as to overlap each other when viewed from the direction perpendicular to the plate surface of the inner plate SP1. Therefore, even in the case of using a configuration using a multiplication mechanism including the first slide member 33, the pinion gear 35, and the second slide member 34 as in the above-described embodiment, it is possible to save the space of the moving mechanism. .
　また、上記実施例においては、移動機構が倍化機構を有する場合について説明した。しかし、移動機構は、倍化機構を有していなくともよい。すなわち、表示装置１０において、移動機構が側板部ＳＰに沿って移動する駆動部材を有し、コンバイナユニット１５及びシャッタ１７が当該駆動部材の移動に従って移動するように構成されていればよい。 In the above embodiment, the case where the moving mechanism has a doubling mechanism has been described. However, the moving mechanism may not have a doubling mechanism. That is, in the display device 10, the moving mechanism may include a driving member that moves along the side plate portion SP, and the combiner unit 15 and the shutter 17 may be configured to move according to the movement of the driving member.
　例えば当該駆動部材は、上記実施例における第２のスライド部材３４に相当する。この場合、例えば、駆動源によって回転する第１のピニオンギア３１が、上記実施例の第１のスライド部材３３を介さずに第２のスライド部材３４の第２のラックＬ２に直接噛み合っていてもよい。この場合においても、第２のスライド部材３４を駆動する第１のピニオンギア３１側に拡張部Ｅを設けることができるため、スペースの有効活用が可能である。 For example, the drive member corresponds to the second slide member 34 in the above embodiment. In this case, for example, even if the first pinion gear 31 rotated by the drive source is directly meshed with the second rack L2 of the second slide member 34 without passing through the first slide member 33 of the above embodiment. Good. Even in this case, since the extended portion E can be provided on the first pinion gear 31 side for driving the second slide member 34, the space can be effectively used.
　すなわち、上記実施例の構成によれば、第２のスライド部材３４の同一の側部に、各々異なった移動経路を及び移動形態を有する様々な部材を複数の係合させることが可能である。これによって、移動機構ひいては表示装置のコンパクト化が可能である。 That is, according to the configuration of the above-described embodiment, it is possible to engage a plurality of various members having different movement paths and movement forms on the same side portion of the second slide member 34. As a result, the moving mechanism and thus the display device can be made compact.
　上述の実施例においては、側板部ＳＰの両方に移動機構が形成されているとしたが、いずれか一方の側板部ＳＰのみに移動機構が形成されていてもよい。また、開口部１３Ｂは、透光性の板材等で覆われていてもよい。 In the above-described embodiment, the movement mechanism is formed on both of the side plate portions SP, but the movement mechanism may be formed only on one of the side plate portions SP. Moreover, the opening 13B may be covered with a light-transmitting plate material or the like.
