以下、添付図面に基づいて、本発明を計器装置に適用した一実施形態を説明する。計器装置は、ケース体３０と、表示板４０と、指針５０と、回路基板６０と、を備えている。 Hereinafter, an embodiment in which the present invention is applied to an instrument device will be described with reference to the accompanying drawings. The instrument device includes a case body 30, a display board 40, a pointer 50, and a circuit board 60.

ケース体３０は硬質の合成樹脂からなり、このケース体３０の後側に回路基板６０が固定されている。表示板４０は、ケース体３０の前側に配設されており、指針５０の指示対象である指標部４１を有している。また、表示板４０の中央には、指針５０のボス部５１が回転可能に挿入される指針挿入孔４０ａが形成されている。 The case body 30 is made of a hard synthetic resin, and the circuit board 60 is fixed to the rear side of the case body 30. The display board 40 is disposed on the front side of the case body 30 and has an indicator portion 41 that is an indication target of the pointer 50. In addition, a pointer insertion hole 40a into which the boss 51 of the pointer 50 is rotatably inserted is formed in the center of the display board 40.

指針５０は、各種の合成樹脂によって形成され、表示板４０の指標部４１を指示する。回路基板６０は、基板本体６１と、基板本体６１の後面側に実装された指針駆動部６２と、基板本体６１の表面側に実装された光源６４，６５と、を備えている。 The pointer 50 is formed of various synthetic resins and points to the indicator portion 41 of the display board 40. The circuit board 60 includes a board body 61, a pointer driving unit 62 mounted on the rear surface side of the board body 61, and light sources 64 and 65 mounted on the surface side of the board body 61.

基板本体６１は、平板状のガラスエポキシ系基材に、指針駆動部６２を駆動させる駆動回路、光源６４，２５を発光させる発光回路等を形成した硬質プリント配線板からなる。駆動回路及び発光回路は、夫々、配線パターン，抵抗，コンデンサ等によって構成される。駆動回路は、制御部から供給される制御信号に基づいて、指針駆動部６２を駆動する。発光回路は、制御部から供給される制御信号に基づいて、光源６４，６５を発光させる。 The board main body 61 is formed of a hard printed wiring board in which a driving circuit for driving the pointer driving unit 62 and a light emitting circuit for emitting the light sources 64 and 25 are formed on a flat glass epoxy base material. The drive circuit and the light emitting circuit are each composed of a wiring pattern, a resistor, a capacitor, and the like. The drive circuit drives the pointer drive unit 62 based on a control signal supplied from the control unit. The light emitting circuit causes the light sources 64 and 65 to emit light based on a control signal supplied from the control unit.

指針駆動部６２は、可動磁石式駆動装置，ステッピングモータ等からなるものである。指針駆動部６２の回動軸６２ａは、基板本体６１に形成された貫通孔２１ａに挿入され、指針駆動部６２の回動軸６２ａには、指針５０が取り付けられる。指針５０のボス部５１は、表示板４０に形成された指針挿入孔４０ａに挿入されている。 The pointer driving unit 62 includes a movable magnet type driving device, a stepping motor, and the like. The turning shaft 62 a of the pointer driving unit 62 is inserted into the through hole 21 a formed in the substrate body 61, and the pointer 50 is attached to the turning shaft 62 a of the pointer driving unit 62. The boss portion 51 of the pointer 50 is inserted into a pointer insertion hole 40 a formed in the display board 40.

基板本体６１の駆動回路は、制御部から供給される制御信号に基づいて、指針駆動部６２を駆動して、制御信号に応じた回転角度で回動軸６２ａを回転させる。回動軸６２ａの回転に応じて指針５０も回転する。これによって、指針５０は、車両速度に応じた所定の回転角度で回転し、表示板４０の指標部４１を指示する。 The drive circuit of the substrate body 61 drives the pointer drive unit 62 based on the control signal supplied from the control unit, and rotates the rotation shaft 62a at a rotation angle corresponding to the control signal. The pointer 50 also rotates according to the rotation of the rotation shaft 62a. Accordingly, the pointer 50 rotates at a predetermined rotation angle corresponding to the vehicle speed, and instructs the indicator portion 41 of the display board 40.

光源６４，６５は、夫々、１個以上の発光ダイオード等によって構成される。光源６４は、表示板４０の指標部４１を透過照明し、光源６５は、指針５０を光輝させる。このような照明によって指標部４１及び指針５０は明るくなるので、ユーザは暗所であっても指標部４１及び指針５０を視認できる。 Each of the light sources 64 and 65 includes one or more light emitting diodes. The light source 64 transmits and illuminates the indicator portion 41 of the display panel 40, and the light source 65 causes the pointer 50 to shine. Since the indicator portion 41 and the pointer 50 are brightened by such illumination, the user can visually recognize the indicator portion 41 and the pointer 50 even in a dark place.
