Description

【発明の詳細な説明】 〔発明の技術分野〕 本発明は、自動・車の自動変速機などにおける車輌用変
速機のシフトレバ−位置表示装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a shift lever position display device for a vehicle transmission, such as an automatic transmission for an automobile.

うなものでは、光源に最も近いポジションと、光源に最
も遠いポジションとに照度差が生じ、好ましくない。Conventionally, in this type of device, when illuminating a translucent position plate displaying each position symbol, one light source is provided on the back side of the position plate to make each position symbol stand out. However, in such a device, a difference in illuminance occurs between the position closest to the light source and the position farthest from the light source, which is not preferable.

る。Therefore, for example, as shown in Japanese Utility Model Publication No. 57-133425, a reflective plate or a reflective box is used in the light source section, or as shown in Japanese Utility Model Publication No. 51-47694, the position plate is made thicker (curved). There are some models in which the distance from the light source to each position symbol is made the same as possible, and each position symbol is made to have the same brightness. There are problems such as restrictions on the shape.

Some systems use an independent light source for each position symbol, but in this case, multiple light sources are required, which requires a large amount of current, and the amount of heat generated by them increases, which requires countermeasures. , it becomes expensive.
