As shown in FIGS. 2A and 2B, the optical path changing unit 4 of the present embodiment includes a retroreflective member 40 that reflects incident light 35 in a direction parallel to the incident direction, and a retroreflective member 40 that transmits part of the incident light 35. and a beam splitter 41 for reflecting the others. The display unit 3 outputs light 35 from the display screen 30 to the retroreflective member 40 and the beam splitter 41, as shown in FIG. 2B.
再帰反射部材４０は、プリズム型又はマイクロビーズ型の再帰反射素子である。本実施の形態の再帰反射部材４０は、一例として、マイクロビーズ型の再帰反射素子である。再帰反射部材４０は、およそ屈折率２の微小な複数のボールレンズが入射面４００の縦横方向に並んで配置されている。 The retroreflective member 40 is a prism-type or microbead-type retroreflective element. The retroreflective member 40 of the present embodiment is, for example, a microbead type retroreflective element. The retroreflective member 40 has a plurality of minute ball lenses with a refractive index of about 2 arranged side by side in the vertical and horizontal directions of the incident surface 400 .
再帰反射部材４０は、図２Ａ及び図２Ｂに示すように、表示部３とおよそ９０°の角度となるように配置されている。なお再帰反射部材４０と表示部３の角度は、９０°に限定されない。 As shown in FIGS. 2A and 2B, the retroreflective member 40 is arranged at an angle of about 90° with the display section 3 . The angle between the retroreflective member 40 and the display section 3 is not limited to 90°.
ビームスプリッタ４１は、図２Ａ及び図２Ｂに示すように、光３５が入射する入射面４１０と、入射面４１０の裏側の面であり、光３５が出射する出射面４１１と、を備えている。ビームスプリッタ４１は、一例として、銀やアルミニウムの薄膜により形成された反射膜を入射面４１０に有している。 As shown in FIGS. 2A and 2B, the beam splitter 41 has an incident surface 410 on which the light 35 is incident, and an output surface 411 which is a surface on the back side of the incident surface 410 and from which the light 35 is emitted. The beam splitter 41 has, for example, a reflection film formed of a silver or aluminum thin film on the incident surface 410 .
ビームスプリッタ４１は、入射面４１０に入射した光３５の一部を反射し、その他を出射面４１１から表示領域４５に出射する。 The beam splitter 41 reflects part of the light 35 incident on the incident surface 410 and emits the other part from the exit surface 411 to the display area 45 .
ビームスプリッタ４１は、筐体１０の上部に配置され、出射面４１１がダッシュボード８０の上面８００に露出するように配置されている。表示部３の表示画面３０と表示領域４５は、ビームスプリッタ４１を対称面として面対称の関係にある。また言い換えるなら表示画面３０と表示領域４５は、図２Ｂの紙面においてビームスプリッタ４１の中心を通る直線を軸として回転対称の関係にある。 The beam splitter 41 is arranged in the upper part of the housing 10 so that the emission surface 411 is exposed on the upper surface 800 of the dashboard 80 . The display screen 30 and the display area 45 of the display unit 3 have a plane-symmetrical relationship with the beam splitter 41 as a plane of symmetry. In other words, the display screen 30 and the display area 45 have a rotationally symmetrical relationship about a straight line passing through the center of the beam splitter 41 in the plane of FIG. 2B.
なおビームスプリッタ４１は、筐体１０の中が見え難くなるように、光の透過率を抑制したスモーク処理が出射面４１１になされても良い。 In addition, the beam splitter 41 may have the exit surface 411 smoked to suppress the light transmittance so that the inside of the housing 10 is difficult to see.
・表示画像３１と空中結像４６について
表示部３の表示画面３０から出射される光３５の光路３６は、まずビームスプリッタ４１によって変更される。次にビームスプリッタ４１の入射面４１０に入射した光３５は、一部が再帰反射部材４０の方向に反射し、光路３６が変更される。 Display Image 31 and Aerial Image Formation 46 First, the optical path 36 of the light 35 emitted from the display screen 30 of the display section 3 is changed by the beam splitter 41 . Next, part of the light 35 incident on the incident surface 410 of the beam splitter 41 is reflected in the direction of the retroreflective member 40, and the optical path 36 is changed.
次に再帰反射部材４０の入射面４００に入射した光３５は、入射した光３５と平行でかつ反対方向に反射し、光路３６が変更される。再帰反射部材４０を反射した光３５は、ビームスプリッタ４１の入射面４１０に入射し、一部が透過して出射面４１１から出射して収束して表示領域４５において空中結像４６を生成する。 Next, the light 35 incident on the incident surface 400 of the retroreflective member 40 is reflected in a direction parallel to and opposite to the incident light 35, and the optical path 36 is changed. The light 35 reflected by the retroreflective member 40 is incident on the incident surface 410 of the beam splitter 41 , partially transmitted, emitted from the exit surface 411 and converged to form an aerial image 46 in the display area 45 .
図２Ｂに示す表示部３側の実線の矢印は、表示部３に表示された表示画像３１である。また図２Ｂに示す表示領域４５側の実線の矢印は、表示領域４５に表示された空中結像４６である。なお矢印の方向は、一例として、表示される画像の向きを示している。 A solid-line arrow on the display unit 3 side shown in FIG. 2B is a display image 31 displayed on the display unit 3 . A solid-line arrow on the display area 45 side shown in FIG. 2B is an aerial image 46 displayed in the display area 45 . Note that the direction of the arrow indicates the orientation of the displayed image, as an example.
なお空中結像４６の位置は、主に、表示部３とビームスプリッタ４１の位置によって定まる。従って空中結像４６は、図２Ｂの紙面からユーザ９側に傾斜させる、つまり反時計回りに傾斜させる場合、表示部３とビームスプリッタ４１を反時計回りに移動させれば良い。 Note that the position of the aerial image 46 is mainly determined by the positions of the display section 3 and the beam splitter 41 . Therefore, when the aerial image 46 is tilted toward the user 9 from the plane of FIG. 2B, that is, tilted counterclockwise, the display section 3 and the beam splitter 41 should be moved counterclockwise.
（変形例について）
図３Ａは、操作装置の配置を説明するための図であり、図３Ｂは、光路変更部を説明するための図である。 (About modification)
FIG. 3A is a diagram for explaining the arrangement of the operating device, and FIG. 3B is a diagram for explaining the optical path changing section.
この変形例では、光路変更部４が再帰反射部材４０とビームスプリッタ４１ではなく、入射面４２０に入射する表示部３の光３５を出射面４２１から出射させ、表示領域４５において空中結像４６として結像させる結像部材４２として構成されている。この結像部材４２は、図３Ａ及び図３Ｂに示すように、筐体１０の上面１０ａに出射面４２１が露出するように配置されている。 In this modification, the optical path changing unit 4 causes the light 35 of the display unit 3 that is incident on the incident surface 420 to be emitted from the emitting surface 421 instead of the retroreflective member 40 and the beam splitter 41, and forms an aerial image 46 in the display area 45. It is configured as an imaging member 42 for imaging. The imaging member 42 is arranged so that the output surface 421 is exposed on the upper surface 10a of the housing 10, as shown in FIGS. 3A and 3B.
結像部材４２は、例えば、多数のマイクロミラー、多数の微小孔、多数の２面反射体などによって構成されている。変形例の結像部材４２は、一例として、孔の側面に直角に組み合わさったマイクロミラーを作成し、これを縦横に並べて構成されている。 The imaging member 42 is composed of, for example, a large number of micromirrors, a large number of microholes, a large number of dihedral reflectors, and the like. As an example, the imaging member 42 of the modified example is constructed by forming micromirrors that are combined perpendicularly to the side surfaces of the holes and arranging them vertically and horizontally.
結像部材４２は、図３Ｂに示すように、結像部材４２を対称面として面対称の位置に空中結像４６を結像する。つまり結像部材４２から表示部３の表示画面３０までの角度αは、図３Ｂに示すように、結像部材４２から表示領域４５までの角度αと等しい。 As shown in FIG. 3B, the imaging member 42 forms an aerial image 46 at a plane-symmetrical position with the imaging member 42 as a plane of symmetry. That is, the angle α from the imaging member 42 to the display screen 30 of the display unit 3 is equal to the angle α from the imaging member 42 to the display area 45 as shown in FIG. 3B.
なお結像部材４２は、図３Ｂに示すように、光３５が結像部材４２から出射した後に交差するので、表示部３に表示された表示画像３１を反転させた空中結像４６を生成する。 Note that, as shown in FIG. 3B, the imaging member 42 intersects the light 35 after exiting from the imaging member 42, so that the display image 31 displayed on the display unit 3 is inverted to generate an aerial image 46. .
（制御部７の構成）
制御部７は、例えば、記憶されたプログラムに従って、取得したデータに演算、加工などを行うＣＰＵ（Central Processing Unit）、半導体メモリであるＲＡＭ（Random Access Memory）及びＲＯＭ（Read Only Memory）などから構成されるマイクロコンピュータである。このＲＯＭには、例えば、制御部７が動作するためのプログラムが格納されている。ＲＡＭは、例えば、一時的に演算結果などを格納する記憶領域として用いられる。 (Configuration of control unit 7)
The control unit 7 includes, for example, a CPU (Central Processing Unit) that performs calculations and processing on acquired data according to a stored program, a semiconductor memory such as a RAM (Random Access Memory) and a ROM (Read Only Memory). It is a microcomputer that This ROM stores, for example, a program for operating the control unit 7 . The RAM is used, for example, as a storage area for temporarily storing calculation results and the like.
制御部７は、操作部２の操作検出部２２から取得した操作検出情報Ｓ１に基づいて操作がなされた操作ノブ２１と操作量の情報を含む操作情報Ｓ３を被制御装置８５に出力する。被制御装置８５は、操作情報Ｓ３に基づいて操作が検出された操作ノブ２１と操作量を判定し、当該操作ノブ２１に割り当てられた機能を実行する。 The control unit 7 outputs to the controlled device 85 operation information S3 including information on the operation knob 21 operated based on the operation detection information S1 acquired from the operation detection unit 22 of the operation unit 2 and the amount of operation. . The controlled device 85 determines the operation knob 21 whose operation has been detected and the amount of operation based on the operation information S3 , and executes the function assigned to the operation knob 21 .
制御部７は、被制御装置８５から所得した画像情報Ｓ４に基づいて表示部３に表示画像３１を表示させる。なお制御部７は、画像情報Ｓ４に基づいて空中結像４６の表示の優先度が低い場合、空中結像４６を表示しない。制御部７は、例えば、操作部２が自動運転時に有効である場合、手動運転時には空中結像４６を表示せず、手動運転時に有効である場合、自動運転時には空中結像４６を表示しない。また制御部７は、例えば、走行中に操作できない機能、つまり停車中にしか操作が許可されない機能が操作部２に割り当てられている場合、空中結像４６を走行中は表示しない。この走行中に操作できない機能とは、一例として、２輪駆動から４輪駆動、４輪駆動から２輪駆動に切り替える機能などの走行中に操作すると走行に支障が生じる機能である。なお制御部７は、警告など優先度が高い場合、機能画像１００に代わって警告などの画像を空中結像４６として表示しても良い。 The control unit 7 causes the display unit 3 to display the display image 31 based on the image information S4 obtained from the controlled device 85 . Note that the control unit 7 does not display the aerial image 46 when the display priority of the aerial image 46 is low based on the image information S4. For example, if the operation unit 2 is effective during automatic operation, the control unit 7 does not display the aerial image 46 during manual operation, and if it is effective during manual operation, the control unit 7 does not display the aerial image 46 during automatic operation. For example, if a function that cannot be operated while the vehicle is running, that is, a function that can only be operated while the vehicle is stopped is assigned to the operation unit 2, the control unit 7 does not display the aerial image 46 while the vehicle is running. The function that cannot be operated while driving is, for example, a function that hinders driving if operated during driving, such as a function to switch from two-wheel drive to four-wheel drive or from four-wheel drive to two-wheel drive. Note that the control unit 7 may display an image such as a warning as the aerial image 46 instead of the functional image 100 when the priority is high such as a warning.
（第１の実施の形態の効果）
本実施の形態に係る操作装置１は、視認性の低下を抑制することができる。この操作装置１は、操作部２の機能画像１００を空中の表示領域４５に空中結像４６として表示するので、ディスプレイに表示する場合と比べて、視認性の低下を抑制することができる。 (Effect of the first embodiment)
The operating device 1 according to the present embodiment can suppress deterioration in visibility. Since the operation device 1 displays the functional image 100 of the operation unit 2 in the display area 45 in the air as the aerial image 46, it is possible to suppress deterioration in visibility compared to displaying on a display.
操作装置１は、ディスプレイを配置する場合と比べて、良好な視界を確保しつつ操作部２の機能を空中結像４６として表示させることができる。 The operation device 1 can display the functions of the operation unit 2 as an aerial image 46 while ensuring a good field of view, compared to the case where a display is arranged.
操作装置１は、操作部２の有効、無効に応じて空中結像４６の表示、非表示を切り替えることができるので、切り替えない場合と比べて、良好な視界を確保することができる。また操作装置１は、警告などの優先度の高い画像を表示するので、操作部に設けられた意匠を点灯させる場合と比べて、機能画像１００以外の表示の自由度が高い。 Since the operation device 1 can switch between display and non-display of the aerial image formation 46 depending on whether the operation unit 2 is enabled or disabled, it is possible to secure a better field of view than when switching is not performed. In addition, since the operation device 1 displays an image with a high priority such as a warning, there is a high degree of freedom in displaying images other than the functional image 100 compared to the case of lighting a design provided on the operation unit.

As shown in FIG. Since the operation device 1 does not block the line of sight of the user 9 by being arranged on the ceiling 84, it is possible to secure a good field of view.
また操作装置１は、天井８４に機能などを表示する表示部を設けた場合と比べて、天井８４を見上げる角度を小さくすることができる。 In addition, the operating device 1 can reduce the angle at which the ceiling 84 is looked up compared to the case where the ceiling 84 is provided with a display section for displaying functions and the like.
［第３の実施の形態］
第３の実施の形態は、操作部に接触すると空中結像を表示する点で他の実施の形態と異なっている。 [Third embodiment]

As shown in FIG. 5, the operation device 1 of the present embodiment includes a contact detection unit 5 that detects contact with the operation unit 2, and a display unit 3 that detects contact with the operation unit 2 by the contact detection unit 5. and a control unit 7 for controlling the display area 45 to display an aerial image 46 .
接触検出部５は、ユーザ９による操作ノブ２１の接触を検出するため、操作ノブ２１に配置されている。接触検出部５は、一例として、ユーザ９の操作指と操作ノブ２１に配置された電極との間に形成される静電容量に基づいて接触を検出するタッチセンサである。接触検出部５は、接触が検出された操作ノブ２１の情報を含む接触情報Ｓ５を制御部７に出力する。 The contact detection unit 5 is arranged on the operation knob 21 in order to detect the contact of the operation knob 21 by the user 9 . The contact detection unit 5 is, for example, a touch sensor that detects contact based on the capacitance formed between the operating finger of the user 9 and an electrode arranged on the operating knob 21 . The contact detection unit 5 outputs to the control unit 7 contact information S5 including information on the operation knob 21 for which contact has been detected.
制御部７は、接触情報Ｓ５に基づく静電容量と接触しきい値７０とを比較し、静電容量が接触しきい値７０以上となった場合、表示部３を制御して空中結像４６を表示させる。 The control unit 7 compares the capacitance based on the contact information S5 with the contact threshold value 70, and when the capacitance exceeds the contact threshold value 70, controls the display unit 3 to form an aerial image. 46 is displayed.
（第３の実施の形態の効果）
