該壁の文字板に近い上部に溝を設け、該壁に文字
板の折り曲げ部を圧入気味に嵌合する構造にする
ことによつて解消されていた。 Conventionally, when instruments such as tachometers and speedometers are lined up individually and each dial plate is provided, in order to prevent light leakage from the lighting bulb at the boundary, it is necessary to set a screen at the boundary between each dial plate of each instrument. , a wall is built integrally from the storage case of each instrument,
This problem has been solved by providing a groove in the upper part of the wall near the dial, and creating a structure in which the bent portion of the dial is fitted into the wall with a slight press fit.
ところが、現在、文字板が光透過で、かつ自発
光式指針を有するコンビネーシヨンメータが主流
をなしてきている。このメータは各文字板と各指

て、前述した漏光防止構造が成立しなくなる欠点
がある。 However, at present, combination meters with light-transmitting dials and self-luminous hands have become mainstream. This meter has each dial plate and a light guide plate (hereinafter referred to as a prism) for emitting light from each pointer.
They are attached to each instrument, and the lighting bulbs are also generally located near the bottom of the folded part of the dial. Therefore, there is a drawback that the above-mentioned light leakage prevention structure is not established.
そこで、本考案は前述の欠点を解消するめに、
各計器の各文字板の境目からの漏光を確実に防止
することを目的とする。 Therefore, in order to eliminate the above-mentioned drawbacks, this invention
The purpose is to reliably prevent light leakage from the boundaries between the dials of each instrument.
そのため本発明では、それぞれがつき合わされ
て、このつき合わされた境目に折り曲げ部が設け

た。 Therefore, in the present invention, the divided dials of the instrument are brought together and a folded part is provided at the boundary where these divided dials are brought together, and the divided dials are arranged approximately directly below the boundary where they are brought together. The lighting bulb, a light leakage prevention component surrounding the bent part of the dial, an L-shaped part that fixes the light leakage prevention component, and an end face facing the lighting bulb, allow the light from the lighting bulb to be directed to the dial and the dial. It has a light leakage prevention structure consisting of a light guide plate that is formed on the back surface of the dial and has a light guide part that leads to the pointer.
次に、本考案を図の構成について説明すると、
１及び２は文字板であり、その境目に互いに平行
で、ほぼ直角に折り曲げた折り曲げ部１ａ，２ａ
を各々有し、透明樹脂材に文字、目盛等が印刷し

ある。７は照明バルブである。そして、プリズム
４，５には、端面が照明バルブと対向した導光部
４ｃ，５ｃまた一体成形されている。 Next, to explain the present invention in terms of the configuration of the diagram,
1 and 2 are dial plates, and bent portions 1a and 2a are parallel to each other and bent at approximately right angles at the boundary between the dial plates.
Each has letters, scales, etc. printed on a transparent resin material. 3 is a self-luminous pointer. 4 and 5 are prisms for causing the pointer 3 to emit light, and are made of a transparent resin material, and the prism 4 and the L-shaped portion 4a having the fixing pin 4b are integrally molded. Reference numeral 6 denotes a black concave part that surrounds the right-angled bent portions 1a and 2a of the dial plates 1 and 2, and is press-fitted and fixed to the pin 4b. 7 is a lighting bulb. The prisms 4 and 5 are also integrally molded with light guide portions 4c and 5c whose end faces face the illumination bulbs.
次に、上記構成においてその機能について説明
すると、バルブ７から発せられた光は、各プリズ
ム４及び５を介して指針３を発行させると共に、
各文字板１及び２内を通つてその数字、目盛等も

曲げ部１ａ，２ａは黒色凹型部品６によつて光が
遮断され、漏光防止が保障される。 Next, to explain the function of the above configuration, the light emitted from the bulb 7 issues the pointer 3 via each prism 4 and 5, and
The numbers, scales, etc. are also emitted through the inside of each dial plate 1 and 2. At this time, the right angle bent portions 1a, 2a of each dial plate 1, 2 are blocked from light by the black concave parts 6, ensuring prevention of light leakage.
次に、本考案の効果について説明すると以下の
ようになる。 Next, the effects of the present invention will be explained as follows.
(1) 各計器の各文字板の境目の折り曲げ部を囲み
かつ導光板に固定された遮光防示部品を設ける
という簡単な構成によつて、照明バルブからの
光をさえぎり、各文字板の境目からの漏光を確
実に防止することができる。(1) A simple structure in which a light-shielding part is provided that surrounds the bend at the boundary between each dial of each instrument and is fixed to the light guide plate, which blocks the light from the lighting bulb and closes the boundary between each dial. It is possible to reliably prevent light leakage from.
(2) 前述したようにプリズムが照明バルブからの
光を指針等に導く役目をするので、漏光防止部
品をプリズムに固定したことにより、照明バル
ブの位置に関係なく、漏光防止が成立する。(2) As mentioned above, the prism serves to guide the light from the lighting bulb to the pointer, etc., so by fixing the light leakage prevention component to the prism, light leakage can be prevented regardless of the position of the lighting bulb.
(3) 文字板の境目の略増したに照明バルブを配置
できるので、１個の照明バルブで、少なくとも
２種の計器を照らすことができ照明バルブの有
効な活用が可能となつた。(3) Since the lighting bulbs can be placed almost at the border of the dial, one lighting bulb can illuminate at least two types of instruments, making effective use of the lighting bulbs possible.
