　ヘッドアップディスプレイ装置ＨＵＤは、表示器１から出射された表示光Ｌを、平面鏡２１と凹面鏡２２の順に反射させた後、ケース５の開口を覆う透光性カバー５０を透過させて、車両のフロントウィンドシールドＷＳに照射する。ヘッドアップディスプレイ装置ＨＵＤから出射される表示光ＬがフロントウィンドシールドＷＳに照射された状態で、可視領域ＤＡの範囲からフロントウィンドシールドＷＳを視認する視点ＥからフロントウィンドシールドＷＳを視認すると、車両前方の景色（実風景）と表示光Ｌの虚像Ｖが重なって見える。ヘッドアップディスプレイ装置ＨＵＤは、車両の走行速度や車両の各種警告情報、経路案内情報などの車両の走行に関わる車両情報を表す画像を表示光Ｌとして出射することで、車両前方の景色と重ねて車両情報を表示できる。 The head-up display device HUD reflects the display light L emitted from the display 1 in the order of the plane mirror 21 and the concave mirror 22, and then transmits the display light L through the translucent cover 50 that covers the opening of the case 5 to front the vehicle. Irradiate the windshield WS. With the display light L emitted from the head-up display device HUD being emitted to the front windshield WS, when the front windshield WS is visually recognized from the viewpoint E where the front windshield WS is visually recognized from the range of the visible area DA, the front of the vehicle is detected. And the virtual image V of the display light L are seen to overlap. The head-up display device HUD emits, as the display light L, an image representing vehicle information relating to vehicle traveling such as vehicle traveling speed, various vehicle warning information, route guidance information, and the like, so as to overlap with the scenery in front of the vehicle. Vehicle information can be displayed.
　表示器１は、例えば、液晶ディスプレイ、あるいは、有機ＥＬディスプレイなどの画像を表示するディスプレイである。表示器１は、制御回路基板４に制御されて所定の画像を表示し、当該画像を表す表示光Ｌを出射する。 The display 1 is, for example, a display such as a liquid crystal display or an organic EL display that displays an image. The display 1 is controlled by the control circuit board 4 to display a predetermined image and emits the display light L representing the image.
　平面鏡２１は、表示器１から出射された表示光Ｌをケース５内で折り曲げる反射鏡であり、表示光Ｌの光路長をケース５内でより長く確保できる。 The plane mirror 21 is a reflecting mirror that bends the display light L emitted from the display 1 in the case 5, and the optical path length of the display light L can be secured longer in the case 5.
　凹面鏡２２は、平面鏡２１が反射した表示光Ｌをケース５の透光性カバー５０に向けて反射する反射鏡である。凹面鏡２２の凹面形状は、表示光Ｌを拡大し、フロントウィンドシールドＷＳの曲面により生じる虚像Ｖの歪みを補正あるいは相殺する形状に設計されている。 The concave mirror 22 is a reflecting mirror that reflects the display light L reflected by the plane mirror 21 toward the translucent cover 50 of the case 5.

The control circuit is, for example, a microcontroller having a CPU, a RAM, and a ROM.
　図２を参照する。ケース５は、透光性カバー５０を有する上ケース５１と、下ケース５２から主に構成される。 Refer to FIG. The case 5 mainly includes an upper case 51 having a translucent cover 50 and a lower case 52.
　透光性カバー５０は、例えば、アクリル樹脂やポリカーボネートなどの樹脂をフィルム状に形成し、表示光Ｌを透過する透光性のカバーである。透光性カバー５０は、ケース５の表示光Ｌが出射する開口から水や塵が入らないように防ぐ。 The translucent cover 50 is, for example, a translucent cover formed by forming a resin such as acrylic resin or polycarbonate into a film shape and transmitting the display light L. The translucent cover 50 prevents water and dust from entering through the opening through which the display light L of the case 5 exits.
　上ケース５１は、ポリカーボネート樹脂やポリプロピレン樹脂などの樹脂を射出成形して形成された不透過な蓋である。上ケース５１は、下ケース５２の上蓋であり下ケース５２と係合する。上ケース５１には表示光Ｌを出射する開口が開けられ、この開口を覆うように透光性カバー５０が接着固定されている。 The upper case 51 is an impermeable lid formed by injection molding a resin such as polycarbonate resin or polypropylene resin. The upper case 51 is an upper lid of the lower case 52 and engages with the lower case 52. An opening for emitting the display light L is opened in the upper case 51, and the translucent cover 50 is adhesively fixed so as to cover the opening.
　上ケース５１は、フランジ部５１０と、Ｕ字フック部５１１と、Ｌ字フック部５１１が一体に形成されている。 The upper case 51 is integrally formed with a flange portion 510, a U-shaped hook portion 511, and an L-shaped hook portion 511.
　フランジ部５１０は、ヘッドアップディスプレイ装置ＨＵＤの左右方向（Ｌｔ－Ｒｔ方向）に一対となるように２つ形成されている。フランジ部５１０は、基部５１０ａと、基部５１０ａを囲む枠状の枠部５１０ｂと、基部５１０ａに穿たれた貫通穴５１０ｃと、から主に構成される。 The two flange portions 510 are formed in a pair in the left-right direction (Lt-Rt direction) of the head-up display device HUD. The flange portion 510 mainly includes a base portion 510a, a frame-shaped frame portion 510b surrounding the base portion 510a, and a through hole 510c formed in the base portion 510a.
　Ｕ字フック部５１１は、フランジ部５１０を基準に車両前方（Ｆｒ方向）の凹面鏡２２が収容される側に形成されている。 The U-shaped hook portion 511 is formed on the side where the concave mirror 22 is housed in front of the vehicle (Fr direction) with the flange portion 510 as a reference.
　Ｌ字フック部５１２は、フランジ部５１０を基準に車両後方（Ｂｋ方向）の平面鏡２１が収容される側に形成されている。 The L-shaped hook portion 512 is formed on the rear side of the vehicle (Bk direction) on the side where the plane mirror 21 is housed, with the flange portion 510 as a reference.
　下ケース５２は、上ケース５１よりも剛性の高い樹脂（例えば、アクリル樹脂やＡＢＳ樹脂、ＰＢＴ樹脂）あるいはアルミナなどの金属製の容器である。下ケース５２には、表示器１、平面鏡２１、凹面鏡２２、回動機構３、制御回路基板４が収容、固定されている。 The lower case 52 is a container made of a resin having higher rigidity than the upper case 51 (for example, acrylic resin, ABS resin, PBT resin) or metal such as alumina. The display unit 1, the plane mirror 21, the concave mirror 22, the rotating mechanism 3, and the control circuit board 4 are housed and fixed in the lower case 52.
　下ケース５２は、フランジ部５２０と、Ｕ字フック受け部５２１と、Ｌ字フック受け部５２２が一体に形成されている。 The lower case 52 is integrally formed with a flange portion 520, a U-shaped hook receiving portion 521, and an L-shaped hook receiving portion 522.
　フランジ部５２０は、ヘッドアップディスプレイ装置ＨＵＤの左右方向（Ｌｔ－Ｒｔ方向）に一対となるように２つ形成されている。フランジ部５２０は、基部５２０ａと、基部５２０ａを囲む枠状の枠部５２０ｂと、基部５２０ａに穿たれた貫通穴５２０ｃと、から主に構成される。 Two flange portions 520 are formed so as to be a pair in the left-right direction (Lt-Rt direction) of the head-up display device HUD. The flange portion 520 is mainly composed of a base portion 520a, a frame-shaped frame portion 520b surrounding the base portion 520a, and a through hole 520c formed in the base portion 520a.
　Ｕ字フック受け部５２１は、上ケース５１のＵ字フック部５１１と係合する突起である。Ｕ字フック受け部５２１とＵ字フック部５１１が係合することにより上ケース５１と下ケース５２とが固定される。Ｕ字フック受け部５２１とＵ字フック５１１によるフック係合は、後述するＬ字フック受け部５２２とＬ字フックによるフック係合に比べ、固定強度は低いが５１１省スペースなため、搭載スペースの狭い車両前方（Ｆｒ方向）の凹面鏡２２が収容される側の係合構造に適している。 The U-shaped hook receiving portion 521 is a protrusion that engages with the U-shaped hook portion 511 of the upper case 51. The upper case 51 and the lower case 52 are fixed by engaging the U-shaped hook receiving portion 521 and the U-shaped hook portion 511. The hook engagement by the U-shaped hook receiving portion 521 and the U-shaped hook 511 is lower in fixing strength than the hook engagement by the L-shaped hook receiving portion 522 and the L-shaped hook, which will be described later, but 511 saves space. It is suitable for the engagement structure on the side where the concave mirror 22 is housed in the narrow vehicle front (Fr direction).
　Ｌ字フック受け部５２２は、上ケース５１のＬ字フック５１２と係合する枠状の貫通穴である。Ｌ字フック受け部５２２とＬ字フック部５１２が係合することにより上ケース５１と下ケース５２とが固定される。 The L-shaped hook receiving portion 522 is a frame-shaped through hole that engages with the L-shaped hook 512 of the upper case 51. The upper case 51 and the lower case 52 are fixed by engaging the L-shaped hook receiving portion 522 and the L-shaped hook portion 512.
　Ｕ字フック５１１及びＬ字フック５１２が樹脂製の上ケース５１に形成され、Ｕ字フック受け部５２１及びＬ字フック受け部５２２が上ケース５１よりも剛性の高い下ケース５２に形成されている。このようにすることで、各フック側が柔らかく、各フック受け部が硬い組み合わせのため、フックが組み付け易く且つフック受け部が破損しにくい。 The U-shaped hook 511 and the L-shaped hook 512 are formed on the resin upper case 51, and the U-shaped hook receiving portion 521 and the L-shaped hook receiving portion 522 are formed on the lower case 52 having higher rigidity than the upper case 51. . By doing so, each hook side is soft and each hook receiving portion is hard, so that the hook is easily assembled and the hook receiving portion is not easily damaged.
　図３を参照する。フランジ部５２０の枠部５２０ｂに囲まれた基部５２０ａに、フランジ部５１０が収容され重なった状態で、ビスＢにより両フランジ部５１０，５２０が車体ＣＢに固定される。これにより、ヘッドアップディスプレイ装置ＨＵＤを車両のインストルメントパネル内の車体ＣＢに取付られる。この際、ビスＢにより両フランジ部５１０，５２０が挟持固定されるため、上ケース５１と下ケース５２とがより強固に固定される。下ケース５２のフランジ部５２０を車体ＣＢにビスＢで固定する力を上ケース５１と下ケース５２とを係止に利用する構成のため、部品点数を増やすことなく、各ケースの固定強度が高まる。 Refer to FIG. Both flange portions 510 and 520 are fixed to the vehicle body CB by screws B in a state where the flange portion 510 is housed and overlapped with the base portion 520a surrounded by the frame portion 520b of the flange portion 520. As a result, the head-up display device HUD is attached to the vehicle body CB in the instrument panel of the vehicle. At this time, since the flanges 510 and 520 are clamped and fixed by the screw B, the upper case 51 and the lower case 52 are more firmly fixed. Since the force for fixing the flange portion 520 of the lower case 52 to the vehicle body CB with the screw B is used for locking the upper case 51 and the lower case 52, the fixing strength of each case is increased without increasing the number of parts. .
　また、上ケース５１のフランジ部５１０は、下ケース５２の枠部５１０ｂに囲まれた基部５１０ａに収容載置される構成のため、下ケース５２のフランジ部５２０から上ケースのフランジ部５１０が外れにくい。 Further, since the flange portion 510 of the upper case 51 is housed and placed in the base portion 510a surrounded by the frame portion 510b of the lower case 52, the flange portion 510 of the upper case is removed from the flange portion 520 of the lower case 52. Hateful.

Mounted on the vehicle,
A head-up display device HUD including a case 5 accommodating a display device 1 that emits display light L, comprising:
The case 5 has a first case 52 fixed to the vehicle body CB of the vehicle with a screw B and a second case 51 engaging with the first case 52.
The second case 51 is fixed to the vehicle body CB of the vehicle with screws B together with the first case 52.
With this configuration, the force for fixing to the vehicle body CB with the screw can be utilized for the engagement between the first case and the second case, so that the fixing strength of each case can be increased without increasing the number of parts.
　上記のヘッドアップディスプレイ装置ＨＵＤの実施形態に限らず、以下に示す変形をしてもよい。 Not limited to the above embodiment of the head-up display device HUD, the following modifications may be made.
　下ケース５２がフック部５１１，５１２を有し、上ケース５１がフック受け部５２１，５２２を有する構成としてもよい。 The lower case 52 may have the hook portions 511 and 512, and the upper case 51 may have the hook receiving portions 521 and 522.
　上ケース５１と下ケース５２とはフック係合に限らず、車体ＣＢに固定するビスＢ以外のビスによって係合してもよい。この場合、車体ＣＢに固定するビスＢの力を両ケース５１，５２の係合に利用できるため、従来のビスによる両ケース５１，５２の構成に比べ用いるビスの数を削減できる。 The upper case 51 and the lower case 52 are not limited to the hook engagement, but may be engaged by a screw other than the screw B fixed to the vehicle body CB. In this case, since the force of the screw B fixed to the vehicle body CB can be used for engaging the cases 51 and 52, the number of screws used can be reduced as compared with the conventional configuration of the cases 51 and 52 using screws.
