Description
図1〜図3は、本発明に係る自動車用車速計の一実施形態を示すもので、図1は車速計の正面図、図2は図1のA−A断面図、図3は図2のB部の拡大断面図である。
上記実施形態では、第1光源91が運転者から直接視認されるのを防止するために遮光部材30を設けたが、遮光部材30を設けるかわりに、導光部材20の外周側斜面部20dに金属調メッキ(例えばクロムメッキ)を施してもよい。
Claims (3)
- 目盛り表示部(10a)が形成され導光性を有する目盛盤(10)と、前記目盛り表示部(10a)に沿って前記目盛盤(10)の表面側に設けられ、表面側に内周側斜面部(20c)および外周側斜面部(20d)の2つの斜面と裏面側に前記目盛盤の表面側に位置する底面部(20e)が形成されて断面が略三角形状とされた略リング状の導光部材(20)と、前記目盛盤の表面に位置した指針と、前記目盛盤の裏面側に位置し前記指針を発光させる光源(93)と、前記目盛盤の裏面側に位置し該目盛盤に光を入射させる光源(92)と、前記目盛盤(10)の裏面側に位置し前記導光部材(20)の前記底面部(20e)を通して前記外周側斜面部(20d)を介して前記目盛表示部を前記目盛盤の表面から照射するとともに、前記内周側斜面部(20c)を発光させる光源(91)と、前記導光部材(20)の前記外周側斜面部(20d)の表面側に配置された遮光部材(30)と、を備えることを特徴とする計器。
- 前記目盛盤(10)は前記目盛り表示部(10a)の内側に数字が形成されていることを特徴とする請求項1に記載の計器。
- 前記導光部材(20)の裏面(20e)側に拡散処理を施したことを特徴とする請求項1または2に記載の計器。
