Description

本発明は、指針計器に関するものである。   The present invention relates to a pointer instrument.

近年、指針計器の視認性を向上させるため、様々な方法が提案されている。例えば、指針が伸縮して見えるようにすることによって、指針が指示する指示値の視認性を向上させようとする指針計器が開示されている(特許文献1を参照)。   In recent years, various methods have been proposed to improve the visibility of the pointer instrument. For example, a pointer instrument is disclosed that attempts to improve the visibility of the indicated value indicated by the pointer by making the pointer appear to expand and contract (see Patent Document 1).

この指針計器は、透明な板材に目盛が形成された目盛板と、目盛板の背後に配置された指針と、目盛板と指針の間に配置されて指針の先端側を覆い隠す遮光板とを備える。遮光板は、指針の回動に従って指針の先端側を覆い隠す長さが短くなるように、即ち、指針が徐々に露出するように構成され、このため、指針の回動に従って指針が伸縮して見えるようできる。したがって、指針の回動位置を、指針の長さと関連付けて認識できるため、これによって、指針計器の視認性を向上させようとするものである。
特開2006−10387号公報
This pointer instrument has a scale plate with a scale formed on a transparent plate, a pointer disposed behind the scale plate, and a light shielding plate that is disposed between the scale plate and the pointer and covers the tip side of the pointer. Prepare. The light-shielding plate is configured such that the length that covers the tip end side of the pointer becomes shorter as the pointer rotates, that is, the pointer is gradually exposed. Can be seen. Therefore, since the rotation position of the pointer can be recognized in association with the length of the pointer, this is intended to improve the visibility of the pointer instrument.
JP 2006-10387 A

しかし、指針が細長いものであるため指針の回動の印象は低く、指針が伸縮して見えるようしても、指針の視認性を向上させる点では一定の限界がある。   However, since the pointer is elongated, the impression of the rotation of the pointer is low, and even if the pointer appears to expand and contract, there is a certain limit in improving the visibility of the pointer.

本発明は、このような事情を考慮してなされたものであり、指針の視認性を向上した指針計器を提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a pointer instrument with improved pointer visibility.

本発明は上記目的を達成する為、以下の技術的手段を採用する。   In order to achieve the above object, the present invention employs the following technical means.

請求項1に記載の指針計器は、回動可能な指針と、指針の回転中心側であって指針の目視側に配置された光透過性を有する意匠部材と、指針と意匠部材の間に配置され、指針と同軸且つ同一速度で回動可能な遮光性部材と、指針と遮光性部材の間に配置され、光透過性と光反射性を有する半透光性部材とを備え、指針の回動軌跡を表す軌跡形状を有して、意匠部材を透過した照明光を軌跡形状の透過像として透過させる透光部が、遮光性部材に形成され、半透光性部材が、指針からの光を目視側に透過させて指針を実像として表示させ、且つ、透過像の光を目視側に反射して透過像を虚像として表示させることを特徴とする。   The pointer instrument according to claim 1 is arranged between a rotatable pointer, a design member having light transmissivity arranged on a rotation center side of the pointer and on a visual side of the pointer, and the pointer and the design member. A light-shielding member that is coaxial with the pointer and rotatable at the same speed, and a semi-transparent member that is disposed between the pointer and the light-shielding member and has a light transmitting property and a light reflecting property. A light-transmitting part having a trajectory shape representing a moving trajectory and transmitting illumination light transmitted through the design member as a trajectory-shaped transmission image is formed on the light-shielding member, and the semi-transparent member is light from the pointer. Is transmitted to the viewing side to display the pointer as a real image, and the light of the transmission image is reflected to the viewing side to display the transmission image as a virtual image.

この構成では、指針と同軸且つ同一速度で回動する遮光性部材に形成された透光部が、光透過性の意匠部材を透過した照明光を、指針の軌跡形状の透過像として透過させ、半透光性部材が、透過像の光を目視側に反射して透過像を虚像として表示させる。これにより、指針の回動軌跡形状の虚像を、指針と同軸且つ同一速度で回動させて表示させることができる。   In this configuration, the light-transmitting part formed on the light-shielding member that is coaxial with the pointer and rotated at the same speed transmits the illumination light transmitted through the light-transmitting design member as a transmission image of the pointer trajectory shape, The translucent member reflects the light of the transmission image to the viewing side and displays the transmission image as a virtual image. Thereby, the virtual image of the shape of the turning locus of the pointer can be displayed by being rotated at the same speed and coaxial with the pointer.

また、この構成では、半透光性部材が、指針からの光を目視側に透過させて実像として指針を表示させる。これらの結果、回動をする指針の実像と、これと同じ回動をする回動軌跡形状の虚像の両方によって、指針の回動を認識させることができるため、指針の視認性を向上できる。   In this configuration, the semi-translucent member transmits the light from the pointer to the viewing side and displays the pointer as a real image. As a result, since the rotation of the pointer can be recognized by both the real image of the pointer that rotates and the virtual image of the rotation locus shape that rotates in the same manner, the visibility of the pointer can be improved.

請求項2に記載の指針計器は、透光部の形状が、目視側から見て指針と重なる位置の近傍から反時計回りに所定長さを有する帯状の円弧であることを特徴とする。これにより、指針の実像の回動と、帯状の円弧の虚像の回動を、より近接させて表示できるため、指針の視認性をより向上できる。   The pointer instrument according to claim 2 is characterized in that the shape of the translucent portion is a belt-like arc having a predetermined length counterclockwise from the vicinity of the position overlapping the pointer when viewed from the viewing side. Thereby, since the rotation of the real image of the pointer and the rotation of the virtual image of the belt-like arc can be displayed closer to each other, the visibility of the pointer can be further improved.

請求項3に記載の指針計器は、指針が指示する指標の補助指標を、補助指標を透過した照明光を透光部が透過像として透過可能な配置で意匠部材に形成することを特徴とする。これにより、回動軌跡形状の虚像を補助指標として表示できるため、指針計器の表示機能をより高めることができる。   The pointer instrument according to claim 3 is characterized in that the auxiliary indicator of the indicator indicated by the pointer is formed on the design member in such a manner that the illuminating light transmitted through the auxiliary indicator can be transmitted as a transmitted image by the light transmitting portion. . Thereby, since the virtual image of the rotation trajectory shape can be displayed as the auxiliary index, the display function of the pointer instrument can be further enhanced.

請求項4に記載の指針計器は、意匠部材を透過照明する光源を備え、光源が、光源の発光色と発光輝度の少なくともいずれかを切り替え可能に構成され、光源の発光色と発光輝度の少なくともいずれかを切り替える制御手段を備えることを特徴とする。これにより、回動軌跡形状の虚像の回動を、色相と明度の少なくともいずれかを切り替えて表示できる。   The pointer instrument according to claim 4 includes a light source that transmits and illuminates the design member, and the light source is configured to be capable of switching at least one of a light emission color and a light emission luminance of the light source. Control means for switching either of them is provided. Thereby, the rotation of the virtual image of the rotation locus shape can be displayed by switching at least one of hue and brightness.

請求項5に記載の指針計器は、制御手段が、指針が所定値以上を指示する場合に、光源の発光色と発光輝度の少なくともいずれかを切り替えることを特徴とする。これにより、指針が所定値以上を指示しているか否かを、より認識し易くできる。   The pointer instrument according to claim 5 is characterized in that, when the pointer indicates a predetermined value or more, the control means switches at least one of the emission color and the emission luminance of the light source. This makes it easier to recognize whether or not the pointer indicates a predetermined value or more.

以下、本発明による指針計器を、自動車に搭載される速度計に適用した場合を例に図面に基づいて説明する。   Hereinafter, the case where the pointer instrument according to the present invention is applied to a speedometer mounted on an automobile will be described with reference to the drawings.

指針計器である速度計1は、運転席前方に配置され、図1に示すように、指針3と、文字21と指標である目盛22とが形成された第1文字盤2と、指針3の回動軌跡形状の虚像52Bとによって、自車両の車速を表示する。虚像52Bは、指針3の近傍から反時計回りに所定長さを有する帯状の円弧の形状を有し、指針3の回動にしたがって、指針3と同軸且つ同一速度で一緒に回動する。尚、指針3の回転中心側であって指針の目視側は、黒色の化粧部材13によって覆われる。   A speedometer 1 that is a pointer instrument is arranged in front of the driver's seat, and as shown in FIG. The vehicle speed of the host vehicle is displayed by the virtual image 52B of the turning locus shape. The virtual image 52B has a belt-like arc shape having a predetermined length counterclockwise from the vicinity of the pointer 3, and rotates together with the pointer 3 at the same speed as the pointer 3 as the pointer 3 rotates. Incidentally, the viewing side of the pointer 3 on the rotation center side is covered with the black decorative member 13.

文字21と目盛22は、これらが透光状態になるように、これらの背景部分が例えば黒色の不透光状態になるように、透光性樹脂からなる第1文字盤2に印刷等により形成される。文字21と目盛22を透過照明する発光ダイオード81は、図2に示すように、第1文字盤2の背後に配置され、発光ダイオード81の発した光は、光路P1に従って、文字21と目盛22を透過照明し、これらを黒色を背景として例えば白色で発光表示させる。   The letters 21 and the scales 22 are formed by printing or the like on the first dial 2 made of a translucent resin so that the background portions thereof are in a non-translucent state such as black so that they are translucent. Is done. As shown in FIG. 2, the light-emitting diode 81 that illuminates and transmits the character 21 and the scale 22 is disposed behind the first dial 2, and the light emitted from the light-emitting diode 81 follows the light path P1 to the character 21 and the scale 22. Are transmitted and illuminated, and these are lit and displayed, for example, in white with a black background.

指針3は、発光ダイオード82の発した光を、光路P2に従って、回転中心側より導入して例えば赤色で発光表示するように構成され、ムーブメント4によって回動する。ムーブメント4は、ステッピングモータ、あるいは交差コイル式回転機等の電気アクチュエータからなり、外部からの電気信号(本実施形態では自動車の速度信号)に対応した角度だけシャフト41を回動させるものである。ムーブメント4のシャフト41に、指針3が固定される。   The pointer 3 is configured to introduce light emitted from the light emitting diode 82 from the rotation center side according to the optical path P <b> 2, and display the light emission, for example, in red, and is rotated by the movement 4. The movement 4 comprises an electric actuator such as a stepping motor or a cross coil type rotating machine, and rotates the shaft 41 by an angle corresponding to an external electric signal (automobile speed signal in the present embodiment). The pointer 3 is fixed to the shaft 41 of the movement 4.

尚、発光ダイオード81、82とムーブメント4は、第1プリント基板10に実装され、発光ダイオード81、82の光は、第1ケース91によって導かれて、それぞれ、文字21と目盛22を透過照明し、指針3を発光表示させる。   The light emitting diodes 81 and 82 and the movement 4 are mounted on the first printed circuit board 10, and the light from the light emitting diodes 81 and 82 is guided by the first case 91 to transmit and illuminate the character 21 and the scale 22, respectively. The pointer 3 is displayed with light emission.

速度計1は、指針3に加えて、意匠部材である第2文字盤5と、遮光性部材である遮光板6と、半透光性部材であるハーフミラー7とを備える。   The speedometer 1 includes a second dial 5 that is a design member, a light-shielding plate 6 that is a light-shielding member, and a half mirror 7 that is a semi-transmissive member, in addition to the pointer 3.

図2において、第2文字盤5は、指針3の回転中心側であって指針3の目視側に配置され、ポリカーボネート樹脂等の透光性樹脂板から、図2と図3に示すように、円錐台状の器の形状で形成される。この形状の母材において、図3と図4に示す側面部51の補助目盛52を残して一方の面(前面または背面)の全面に、遮光性の例えば黒色の遮光膜53(図7)を形成する。これにより、光透過性を有し、目盛22を補助する補助指標である補助目盛52が形成された第2文字盤5を形成する。   In FIG. 2, the second dial 5 is disposed on the rotation center side of the pointer 3 and on the viewing side of the pointer 3, and from a translucent resin plate such as polycarbonate resin, as shown in FIGS. 2 and 3. It is formed in the shape of a truncated cone. In the base material of this shape, for example, a black light-shielding film 53 (FIG. 7) having a light-shielding property is provided on the entire surface of one surface (front surface or back surface) except for the auxiliary scale 52 of the side surface portion 51 shown in FIGS. Form. Thereby, the 2nd dial 5 which has the light transmittance and in which the auxiliary | assistant scale 52 which is an auxiliary | assistant parameter | index which assists the scale 22 was formed is formed.

補助目盛52を透過照明する光源である発光ダイオード83,84は、図2に示すように、第2文字盤5の目視側(図2において左側)に配置され、発光ダイオード83の発した例えば青色光、または、発光ダイオード84の発した例えば赤色光は、光路P3に従って、補助目盛52を透過照明する。図2は、発光ダイオード83が点燈し、発光ダイオード84が消燈している状態を示す。   As shown in FIG. 2, the light emitting diodes 83 and 84 that are light sources that transmit and illuminate the auxiliary scale 52 are arranged on the viewing side (left side in FIG. 2) of the second dial 5, for example, blue light emitted from the light emitting diode 83. Light or, for example, red light emitted from the light emitting diode 84 illuminates the auxiliary scale 52 through the optical path P3. FIG. 2 shows a state in which the light emitting diode 83 is turned on and the light emitting diode 84 is turned off.

尚、発光ダイオード83、84は、第2プリント基板11に実装され、発光ダイオード83、84の光は、第2ケース92によって導かれて、それぞれ、補助目盛52を透過照明する。第2文字盤5と第2プリント基板11と第2ケース92は、化粧部材13に固定される。   The light emitting diodes 83 and 84 are mounted on the second printed circuit board 11, and the light from the light emitting diodes 83 and 84 is guided by the second case 92 to transmit and illuminate the auxiliary scale 52. The second dial plate 5, the second printed circuit board 11, and the second case 92 are fixed to the decorative member 13.

遮光板6は、指針3と第2文字盤5の間において第2文字盤5に近接して配置され、シャフト41に固定されて指針3と同軸且つ同一速度で回動する。遮光板6は、ポリカーボネート樹脂等の透光性樹脂板から、図2と図5に示すように、円錐台状の器の形状で形成される。この形状の母材において、図5と図6に示す側面部61の透光部62を残して一方の面(前面または背面)の全面に、遮光性の例えば黒色の遮光膜63(図7)を形成し、これにより、帯状の円弧の透光部62が形成された遮光板6を形成する。   The light shielding plate 6 is disposed between the pointer 3 and the second dial 5 in the vicinity of the second dial 5, is fixed to the shaft 41, and rotates coaxially and at the same speed as the pointer 3. The light shielding plate 6 is formed from a translucent resin plate such as a polycarbonate resin in the shape of a truncated cone as shown in FIGS. In the base material of this shape, for example, a black light shielding film 63 (FIG. 7) having a light shielding property on the entire surface of one surface (front surface or back surface) except for the light transmitting portion 62 of the side surface portion 61 shown in FIGS. Thus, the light shielding plate 6 in which the band-like arc-shaped translucent portion 62 is formed is formed.

図5は、遮光板6を目視側から見た平面図であり、図6は、遮光板6の側面部61の展開図を目視側から見た図である。図5に示すように、即ち、透光部62が目視側から見て指針3と重なる位置の近傍から反時計回りに配置されるように、指針3と遮光板6をシャフト41に固定する。これにより、目視側から見て指針3と重なる位置の近傍から反時計回りに所定長さを有する帯状の円弧の形状を有する透光部62が、即ち、指針3の回動軌跡を表す軌跡形状を有する透光部62が形成される。   5 is a plan view of the light shielding plate 6 viewed from the viewing side, and FIG. 6 is a development view of the side surface 61 of the light shielding plate 6 viewed from the viewing side. As shown in FIG. 5, that is, the pointer 3 and the light shielding plate 6 are fixed to the shaft 41 so that the translucent portion 62 is arranged counterclockwise from the vicinity of the position overlapping the pointer 3 when viewed from the viewing side. Thereby, the translucent part 62 having the shape of a belt-like arc having a predetermined length counterclockwise from the vicinity of the position overlapping the pointer 3 when viewed from the viewing side, that is, the locus shape representing the turning locus of the pointer 3 A translucent part 62 having the above is formed.

グラデーション部62Aにおいて透光部62の光透過性が反時計回りの方向へ向かって徐々に低下するように、例えば、遮光膜63を網点状に形成する。   For example, the light shielding film 63 is formed in a halftone dot shape so that the light transmittance of the light transmitting portion 62 gradually decreases in the counterclockwise direction in the gradation portion 62A.

尚、第2文字盤5と遮光板6は、例えば、透光性樹脂を円錐台状の器の形状に成形する際に同時に遮光膜53,63を形成するインモールド成形転写によって形成されたり、平板状の透光性樹脂に遮光膜53,63をスクリーン印刷した後に、円錐台状の器の形状に圧空成形することによって形成される。   The second dial plate 5 and the light shielding plate 6 are formed by, for example, in-mold molding transfer that simultaneously forms the light shielding films 53 and 63 when the translucent resin is molded into the shape of a truncated cone. After the light shielding films 53 and 63 are screen-printed on a plate-like translucent resin, they are formed by pressure forming in the shape of a truncated cone.

ハーフミラー7は、指針3と遮光板6の間に配置され、ポリカーボネート樹脂等の透光性樹脂板から、図2に示すように、円錐台状の器から底面を取り除いた形状で形成される。この形状の母材において一方の面(前面または背面)の全面に、光透過性と光反射性を有するように膜厚を調整した、例えばアルミニウム薄膜71(図7)をメッキや蒸着等で形成し、これにより、ハーフミラー7を形成する。   The half mirror 7 is disposed between the pointer 3 and the light shielding plate 6 and is formed in a shape obtained by removing a bottom surface from a frustoconical vessel as shown in FIG. 2 from a translucent resin plate such as polycarbonate resin. . For example, an aluminum thin film 71 (FIG. 7) is formed on the entire surface of one surface (front surface or back surface) of this shape by adjusting the film thickness so as to have light transmission and light reflection, such as plating or vapor deposition. Thus, the half mirror 7 is formed.

点燈した発光ダイオード83が発した青色光は、図7の光路P3に従って、補助目盛52を透過照明し、この透過照明光は、外形が透光部6の形状であって補助目盛52の形状を有する透過像52Aとして透光部62を透過する。透過像52Aは、図3において、透光部62(グラデーション部62Aを含む)内において補助目盛52を透過した照明光による透過像である。透光部62は、指針3と同軸且つ同一速度で回動するため、透過像52Aも指針3と同軸且つ同一速度で回動する。また、透光部62が、その回動位置にかかわらず、補助目盛52の透過照明光を、透過像52Aとして透過可能なように、構成される。   The blue light emitted from the light-emitting diode 83 lit through the auxiliary scale 52 in accordance with the optical path P3 in FIG. 7, and the transmitted illumination light has an outer shape that is the shape of the transparent portion 6 and the shape of the auxiliary scale 52. The light transmitting part 62 is transmitted as a transmission image 52A having In FIG. 3, the transmission image 52A is a transmission image by illumination light transmitted through the auxiliary scale 52 in the light transmitting portion 62 (including the gradation portion 62A). Since the translucent part 62 rotates coaxially and at the same speed as the pointer 3, the transmitted image 52A also rotates coaxially and at the same speed as the pointer 3. Further, the translucent part 62 is configured so that the transmitted illumination light of the auxiliary scale 52 can be transmitted as the transmitted image 52A regardless of the rotation position.

ハーフミラー7は、図7の光路P3に従って、透過像52Aの光を目視側に反射して透過像52Aを虚像52Bとして表示させる。また、ハーフミラー7は、指針3の先端側の光を、即ち、光路P2に従って、発光ダイオード82が発した光を導入して発光表示した指針3の先端側の光を、目視側に透過させて先端側を実像として表示させる。また、ハーフミラー7は、光路P1に従って、文字21と目盛22を透過照明した発光ダイオード81が発した光を、目視側に透過させて文字21と目盛22を実像として表示させる。   The half mirror 7 reflects the light of the transmission image 52A to the viewing side and displays the transmission image 52A as a virtual image 52B according to the optical path P3 of FIG. Further, the half mirror 7 transmits the light on the tip side of the pointer 3, that is, the light on the tip side of the pointer 3 that is emitted and displayed by introducing the light emitted from the light emitting diode 82 according to the optical path P <b> 2 to the viewing side. To display the tip side as a real image. In addition, the half mirror 7 transmits the light emitted from the light emitting diode 81 that illuminates and transmits the character 21 and the scale 22 to the viewing side according to the optical path P1, and displays the character 21 and the scale 22 as a real image.

尚、第1文字盤2と、ハーフミラー7と、第1ケース91と、第1プリント基板10と、化粧部材13は、シリンダ14に固定される。   The first dial 2, the half mirror 7, the first case 91, the first printed circuit board 10, and the decorative member 13 are fixed to the cylinder 14.

制御手段である制御装置12は、マイクロコンピュータ等から構成され、図8に示すように、制御装置12には、当該自動車の車速を検出する速度センサ15が、その信号を入力可能に接続される。また、速度センサ15からの検出信号に応じて制御装置12によって制御されるムーブメント4や、発光ダイオード81−84が、制御装置12に接続される。   The control device 12 which is a control means is composed of a microcomputer or the like. As shown in FIG. 8, a speed sensor 15 for detecting the vehicle speed of the automobile is connected to the control device 12 so that the signal can be input. . Further, the movement 4 controlled by the control device 12 according to the detection signal from the speed sensor 15 and the light emitting diodes 81 to 84 are connected to the control device 12.

指針3が、所定値である100km/hを表す「100」の文字21より反時計回り側を指示する場合に発光ダイオード84を消燈して発光ダイオード83を点燈し、指針3が「100」の文字21を含めてこれより時計回り側を指示する場合に発光ダイオード84を点燈して発光ダイオード83を消燈するように、制御装置12が構成される。また、この切替値は、図示しない設定手段により切り替えることが可能に構成される。   When the pointer 3 indicates the counterclockwise direction from the character “100” 21 representing the predetermined value of 100 km / h, the light emitting diode 84 is turned off and the light emitting diode 83 is turned on. The control device 12 is configured to turn on the light-emitting diode 84 and turn off the light-emitting diode 83 when the clockwise direction including the character 21 is indicated. Further, the switching value is configured to be switched by setting means (not shown).

上述したように構成された本実施形態による速度計1の作動について説明する。   The operation of the speedometer 1 according to the present embodiment configured as described above will be described.

図示しないイグニッションスイッチがオンされると、図8において、制御装置12は、それを検出して作動を開始する。即ち、制御装置12は、速度センサ15からの信号に基づき、車速を算出し、これに対応した角度だけシャフト41を回動させるように、ムーブメント4を制御する。又、この時、制御装置12は、発光ダイオード81,82を点燈させ、車速が100km/h未満の場合、発光ダイオード84を消燈した状態で発光ダイオード83を点燈する。   When an ignition switch (not shown) is turned on, in FIG. 8, the control device 12 detects it and starts operation. That is, the control device 12 calculates the vehicle speed based on the signal from the speed sensor 15 and controls the movement 4 so as to rotate the shaft 41 by an angle corresponding to the vehicle speed. At this time, the control device 12 turns on the light emitting diodes 81 and 82, and turns on the light emitting diode 83 with the light emitting diode 84 turned off when the vehicle speed is less than 100 km / h.

点燈した発光ダイオード81の発した光は、図7において、光路P1に従って、文字21と目盛22を透過照明し、これらを黒色を背景として白色で発光表示させる。ハーフミラー7は、光路P1に従って、文字21と目盛22を透過照明した発光ダイオード81の発した光を、目視側に透過させて文字21と目盛22を実像として表示させる。   In FIG. 7, the light emitted from the light-emitting diode 81 that has been lit illuminates and transmits the letters 21 and the scales 22 according to the optical path P1, and displays them in white with a black background. The half mirror 7 transmits the light emitted from the light emitting diode 81 that has transmitted and illuminated the character 21 and the scale 22 to the viewing side according to the optical path P1, and displays the character 21 and the scale 22 as a real image.

点燈した発光ダイオード82の発した光は、光路P2に従って、指針3に導入されて指針3を赤色で発光表示させる。ハーフミラー7は、発光表示した指針3の先端側の光を、目視側に透過させて指針3の先端側を実像として表示させる。   The light emitted from the light-emitting diode 82 turned on is introduced into the pointer 3 according to the optical path P2, and the pointer 3 is lit and displayed in red. The half mirror 7 transmits the light emitted from the tip side of the pointer 3 to the viewing side and displays the tip side of the pointer 3 as a real image.

点燈した発光ダイオード83の発した青色光は、光路P3に従って、補助目盛52を透過照明し、この透過照明光は、外形が透光部6の形状であって補助目盛52の形状を有する青色の透過像52Aとして透光部62を透過する。ハーフミラー7は、光路P3に従って、透過像52Aの光を目視側に反射して透過像52Aを青色の虚像52Bとして表示させる。透光部62は、指針3と同軸且つ同一速度で回動するため、透過像52Aも指針3と同軸且つ同一速度で回動する。このため、図1において、透光部6の形状であって補助目盛52の形状を有する青色の虚像52Bも、指針3と同軸且つ同一速度で回動する。   The blue light emitted from the light-emitting diode 83 that has been lit illuminates the auxiliary scale 52 in accordance with the optical path P3. The transmitted illumination light has a blue outer shape that is the shape of the transparent portion 6 and has the shape of the auxiliary scale 52. The transmitted image 52A is transmitted through the light transmitting portion 62. The half mirror 7 reflects the light of the transmission image 52A to the viewing side according to the optical path P3 and displays the transmission image 52A as a blue virtual image 52B. Since the translucent part 62 rotates coaxially and at the same speed as the pointer 3, the transmitted image 52A also rotates coaxially and at the same speed as the pointer 3. For this reason, in FIG. 1, the blue virtual image 52 </ b> B having the shape of the translucent portion 6 and the shape of the auxiliary scale 52 is also rotated coaxially with the pointer 3 at the same speed.

即ち、目視側から見て指針3と重なる位置の近傍から反時計回りに所定長さを有する帯状の円弧の形状であって補助目盛52の形状を有する青色の虚像52Bが、指針3と同軸且つ同一速度で回動する。これにより、図1において、指針3の回動軌跡形状の虚像52Bを、指針3と同軸且つ同一速度で回動させて表示させることができる。また、実像として指針3の先端側を表示させる。これらの結果、回動をする指針3の先端側の実像と、これと同じ回動をする回動軌跡形状の虚像52Bの両方によって、指針3の回動を認識させることができるため、指針3の視認性を向上できる。   That is, a blue virtual image 52B having a shape of a belt-like arc having a predetermined length counterclockwise from the vicinity of the position overlapping the pointer 3 when viewed from the viewing side and the shape of the auxiliary scale 52 is coaxial with the pointer 3 and Rotates at the same speed. Thereby, in FIG. 1, the virtual image 52 </ b> B in the shape of the turning locus of the pointer 3 can be rotated and displayed at the same speed and coaxial with the pointer 3. Further, the tip side of the pointer 3 is displayed as a real image. As a result, since the rotation of the pointer 3 can be recognized by both the real image on the distal end side of the rotating pointer 3 and the virtual image 52B having the rotation locus shape that rotates in the same manner, the pointer 3 can be recognized. Visibility can be improved.

また、指針3の実像の回動と、帯状の円弧の虚像52Bの回動を、より近接させて表示しているため、指針3の視認性をより向上できる。   Further, since the rotation of the real image of the pointer 3 and the rotation of the band-like arcuate virtual image 52B are displayed closer to each other, the visibility of the pointer 3 can be further improved.

また、回動軌跡形状の虚像52Bを補助目盛52として表示できるため、速度計1の表示機能をより高めることができる。   Moreover, since the virtual image 52B of the rotation locus shape can be displayed as the auxiliary scale 52, the display function of the speedometer 1 can be further enhanced.

車速が100km/h以上になると、制御装置12は、発光ダイオード84を点燈して発光ダイオード83を消燈する。点燈した発光ダイオード84の発した赤色光は、図7において、光路P3に従って、補助目盛52を透過照明し、この透過照明光は、赤色の透過像52Aとして透光部62を透過する。ハーフミラー7は、光路P3に従って、透過像52Aの光を目視側に反射して透過像52Aを赤色の虚像52Bとして表示させる。   When the vehicle speed becomes 100 km / h or higher, the control device 12 turns on the light emitting diode 84 and turns off the light emitting diode 83. In FIG. 7, the red light emitted from the lighted light emitting diode 84 is transmitted through the auxiliary scale 52 along the optical path P3, and this transmitted illumination light passes through the light transmitting portion 62 as a red transmitted image 52A. The half mirror 7 reflects the light of the transmission image 52A to the viewing side according to the optical path P3 and displays the transmission image 52A as a red virtual image 52B.

これにより、図1において、青色から赤色に切り替わった虚像52Bを、指針3と同軸且つ同一速度で回動させて表示させることができる。したがって、指針3が100km/h以上を指示しているか否かを、より認識し易くできる。   Thereby, in FIG. 1, the virtual image 52B switched from blue to red can be displayed coaxially with the pointer 3 and rotated at the same speed. Therefore, it can be more easily recognized whether or not the pointer 3 indicates 100 km / h or more.

以上説明した本発明の一実施形態による指針計器である速度計1は、回動可能な指針3と、指針3の回転中心側であって指針3の目視側に配置された光透過性を有する意匠部材である第2文字盤5と、指針3と第2文字盤5の間に配置され、指針3と同軸且つ同一速度で回動可能な遮光性部材である遮光板6と、指針3と遮光板6の間に配置され、光透過性と光反射性を有する半透光性部材であるハーフミラー7とを備え、指針3の回動軌跡を表す軌跡形状を有して、第2文字盤5を透過した照明光を軌跡形状の透過像52Aとして透過させる透光部62が、遮光板6に形成され、ハーフミラー7が、指針3からの光を目視側に透過させて指針3を実像として表示させ、且つ、透過像52Aの光を目視側に反射して透過像52Aを虚像52Bとして表示させる。   The speedometer 1 which is a pointer instrument according to an embodiment of the present invention described above has a rotatable pointer 3 and light transmittance disposed on the rotation center side of the pointer 3 and on the viewing side of the pointer 3. A second dial 5 that is a design member; a light shielding plate 6 that is disposed between the pointer 3 and the second dial 5 and that is coaxial with the pointer 3 and rotatable at the same speed; The second character is disposed between the light shielding plates 6 and includes a half mirror 7 which is a semi-transparent member having light transmissivity and light reflectivity, and has a trajectory shape representing the rotation trajectory of the pointer 3. A light-transmitting portion 62 that transmits illumination light transmitted through the board 5 as a trajectory-shaped transmission image 52A is formed on the light shielding plate 6, and the half mirror 7 transmits the light from the pointer 3 to the viewing side to guide the pointer 3. The transmission image 52A is displayed as a real image, and the light of the transmission image 52A is reflected to the viewing side to convert the transmission image 52A to the virtual image 52B. To to display.

これにより、指針の視認性を向上した指針計器を提供できる。   Thereby, the pointer instrument which improved the visibility of the pointer can be provided.
