Description

本発明は、指針式表示装置に関し、より詳細には、文字板に付した目盛等の指標と計測量に応じて回動される指針とを協働して観測者に前記計測量を表示する指針式表示装置に関するものである。   The present invention relates to a pointer-type display device, and more specifically, displays an indicator such as a scale attached to a dial and a pointer rotated in accordance with the measured amount to the observer. The present invention relates to a pointer type display device.

一般に車両等の移動体には、その速度及びエンジン回転数等の計測値を表示する指針式表示装置が搭載されている。この指針式表示装置は、表面に目盛及び数字、文字または記号等の指標が設けられた文字板と、この文字板の前面に配置される指針と、計測量に応じて指針を駆動する内機と、回路パターンが設けられ内機が固定される配線板と、をメータケースに収容して構成している。   In general, a moving object such as a vehicle is equipped with a pointer-type display device that displays measured values such as speed and engine speed. This pointer-type display device includes a dial having a scale and indicators such as numerals, characters, symbols, etc. on the surface, a pointer disposed on the front of the dial, and an internal unit that drives the pointer in accordance with the measurement amount. And a wiring board on which a circuit pattern is provided and the internal unit is fixed, is housed in a meter case.

上述した文字板の指標は、例えば、前記指標に対応する意匠パターンを印刷抜きとして光透過性に形成し、それ以外の部分を黒色系印刷として光不透過性に形成している。そして、メータケース内（文字板の裏側）に設けているバルブの光を意匠パターンに透過させることで、指標を明るく照明して運転者に視認させている。   The index of the dial described above is formed, for example, in a light-transmissive manner by printing a design pattern corresponding to the above-mentioned index, and other portions are formed in a light-impermeable manner as black printing. Then, the indicator light is illuminated brightly and made visible to the driver by transmitting the light of the bulb provided in the meter case (the back side of the dial) to the design pattern.

また、上述した車両用表示装置は、デザイン変更により、文字板上の各表示部の配置が変わって表示部の形状、寸法が変わる場合には、デザインの変更の度に文字板を新規に製造すると共に、他の構成部材である枠部材や基板をも新規に製造する必要があったため、製造コストが増大してしまうという問題が生じていた。   In addition, when the above-described display device for a vehicle changes the arrangement of each display unit on the dial plate due to a design change and the shape and dimensions of the display unit change, a new dial plate is manufactured each time the design is changed. At the same time, there is a problem that the manufacturing cost increases because it is necessary to newly manufacture a frame member and a substrate which are other constituent members.

そこで、車両用表示装置には、前面または一部を液晶ディスプレイや有機ＥＬ（Electro Luminescence）素子などの表示デバイスを備えるものがあった。そして、このような車両用表示装置では、その表示デバイスに例えばウォーニング、インジケータ、ＡＴ（オートマチックトランスミッション）車のシフトポジション等を表示するようにしていた。   Therefore, some vehicle display devices include a display device such as a liquid crystal display or an organic EL (Electro Luminescence) element on the front surface or a part thereof. In such a vehicle display device, for example, a warning, an indicator, a shift position of an AT (automatic transmission) vehicle, and the like are displayed on the display device.

また、運転者等に対する新たな視覚効果を得るための車両用表示装置が提案されてきた。該指針式表示装置は、文字板の表面側に文字板から離間させて透明カバーを配設し、該透明カバー部分に文字板に対して浮遊状態となるように小表示部を配設するようにした。これにより、小表示部が文字板の表面に対して宙に浮いた状態に運転者に視認させることで、立体感のある新たな視覚効果を提供してきた（特許文献１）。
特開２００４−１３２７５６号公報 In addition, a display device for a vehicle for obtaining a new visual effect for a driver or the like has been proposed. In the pointer-type display device, a transparent cover is disposed on the surface side of the dial plate so as to be separated from the dial plate, and a small display unit is disposed on the transparent cover portion so as to be in a floating state with respect to the dial plate. I made it. Thus, a new visual effect with a three-dimensional effect has been provided by allowing the driver to visually recognize the small display unit floating in the air with respect to the surface of the dial (Patent Document 1).

Then, when the light source 23 is turned on by a control unit (not shown), the design light transmitting part 22a shines because the light transmits the design light transmitting part 22a.

次に、上述した構成の指針式表示装置１０における本発明に係る動作（作用）の一例を以下に説明する。   Next, an example of the operation (action) according to the present invention in the pointer type display device 10 having the above-described configuration will be described below.

指針式表示装置１０の表示開始に応じて光源１８，１９が点灯されると、光源１８が発した光は、文字板１１の受光部１１ｂで受光され、この光は、文字板１１内を導かれた光は指標１６にて観測者に向かって反射されると共に、指標１６が設けられていない文字板１１の反対面１１ａから投影部材１７に向かって出射されることで、投影部材１７には指標１６の各々の影１６ｓが写し出される。   When the light sources 18 and 19 are turned on in response to the display start of the pointer type display device 10, the light emitted from the light source 18 is received by the light receiving portion 11 b of the dial plate 11, and this light is guided through the dial plate 11. The emitted light is reflected toward the observer by the index 16 and is emitted toward the projection member 17 from the opposite surface 11a of the dial plate 11 on which the index 16 is not provided. Each shadow 16s of the index 16 is projected.

また、光源１９が発した光は、基部１２ａで受光され、この光は、指示部１２ｂの先端まで導光され、指示部１２ｂの底面に施された着色層で反射されて指示部１２ｂを光輝させている。そして、指針１２が計測量に応じて回動されて文字板１１の指標１６と指針１２の指示部１２ｂとを共同して計測量が表示される。   The light emitted from the light source 19 is received by the base 12a, and the light is guided to the tip of the instruction unit 12b and reflected by the colored layer applied to the bottom surface of the instruction unit 12b to shine the instruction unit 12b. I am letting. Then, the pointer 12 is rotated according to the measurement amount, and the measurement amount is displayed in cooperation with the indicator 16 of the dial 11 and the instruction portion 12b of the pointer 12.

よって、指標１６を投光性部材で形成した文字板１１に設け、その指標１６の影１６ｓを投影部材１７に投影するようにしたことから、指標１６が中空にあるように観測者に視認させ、かつ、その指標１６の影１６ｓを投影部材１７にて視認させることができるため、指標１６を立体的に表示することができる。従って、指針式表示装置１０における表示に新規性を得ることができるため、表品価値を向上させることができる。   Therefore, since the index 16 is provided on the dial 11 formed of a light projecting member and the shadow 16s of the index 16 is projected onto the projection member 17, the observer can visually recognize that the index 16 is hollow. Moreover, since the shadow 16s of the index 16 can be visually recognized by the projection member 17, the index 16 can be displayed three-dimensionally. Therefore, novelty can be obtained in the display on the pointer-type display device 10, so that the value of the product can be improved.

また、指針１２と文字板１１をドーム形状の表ガラス２０で覆うようにしたことから、ドーム形状の表ガラス２０を介して指標１６とその影１６ｓを視認させることができるため、観測者に新規性のある表示を視認させることができる。   Further, since the pointer 12 and the dial plate 11 are covered with the dome-shaped surface glass 20, the indicator 16 and its shadow 16s can be visually recognized through the dome-shaped surface glass 20, so that the observer is new. Can be visually recognized.

さらに、図示しない制御部がシートベルトを着用せずに、観測者が車両を移動させようとしていることを検出して光源２３が点灯されると、その光が意匠透光部２２ａを透光することで、意匠透光部２２ａは光輝する。よって、表ガラス２０の非透光部２２に、シートベルトのウォーニングが表示されるため、指針式表示装置１０における表示スペースを有効利用することができる。   Further, when the control unit (not shown) detects that the observer is moving the vehicle without wearing the seat belt and the light source 23 is turned on, the light is transmitted through the design translucent unit 22a. Thereby, the design translucent part 22a shines. Therefore, since the warning of the seat belt is displayed on the non-translucent portion 22 of the front glass 20, the display space in the pointer type display device 10 can be used effectively.

なお、上述した本最良の形態では、ドーム状の表ガラス２０によって文字板１１及び指針１２を覆う構成とした場合について説明したが、本発明はこれに限定するものではなく、板状の表ガラスで覆ったり、複数の指針式表示装置１０を１枚の表ガラスで覆うなど車両のデザイン等に応じて種々異なる形態とすることができる。   In the above-described best mode, the case where the dial 11 and the pointer 12 are covered with the dome-shaped front glass 20 has been described. However, the present invention is not limited to this, and the plate-shaped front glass is used. Or a plurality of pointer type display devices 10 may be covered with a single front glass depending on the design of the vehicle.

また、文字板１１についても、上述した本最良の形態では、指標１６を設ける部分が傾斜面となるように形成する場合について説明したが、本発明はこれに限定するものではなく、文字板１１を平板状、円弧状などとして形成するような形態とすることもできる。   In the above-described best mode, the dial 11 is also formed so that the portion where the index 16 is provided is an inclined surface. However, the present invention is not limited to this and the dial 11 is not limited thereto. Can be formed in a flat plate shape, an arc shape, or the like.
