本発明は自動車の室内後写鏡等に使われる防眩ミラー等
のミラーの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing mirrors such as anti-glare mirrors used in automobile interior rear view mirrors and the like.
従来ミラーはガラス又は透明プラスチ・ツクで作られて
いた。ガラスで作られたミラーは衝撃力により破損しや
すく、人体に対する安全性に問題があり、また、製造に
多く工程が必要で大量生産にも問題がある。一方、透明
プラスチック製のミラーは、外力、ｆｌｎ’を度変化等
により反り、波打ちなどの変形が起りやすいため、軽量
上取扱いやすい、大量生産が容易であるという利点を有
するにもかかわらず、未だ大（１ｉ′に使用されるに至
っていない。Traditionally mirrors have been made of glass or clear plastic. Mirrors made of glass are easily damaged by impact forces, which poses safety concerns for the human body, and also poses problems in mass production as many manufacturing steps are required. On the other hand, transparent plastic mirrors are susceptible to warping, waving, and other deformations due to external forces and changes in fln', so despite having the advantages of being lightweight, easy to handle, and easy to mass-produce, Large (has not yet been used for 1i').
本発明は従来のガラスや透明プラスチック製のミラーの
持っていた欠点を改良する方法であって、その要旨は、
鏡面を有する金属板等の補強板の鏡面側に反射膜を形成

するミラーの製造方法である。The present invention is a method for improving the drawbacks of conventional mirrors made of glass or transparent plastic, and its gist is as follows:
A method for manufacturing a mirror, comprising forming a reflective film on the mirror side of a reinforcing plate such as a metal plate having a mirror surface, and integrally molding a flat plate or prism made of transparent plastic on the reflective film of the reinforcing plate. It is.
本発明を図を用いて説明する。第１図は本発明により得
られるミラーの一例である防眩ミラーの斜視図で、第２
図は第１図のＡ−Ａ断面図である。The present invention will be explained using figures. FIG. 1 is a perspective view of an anti-glare mirror, which is an example of a mirror obtained by the present invention.
The figure is a sectional view taken along the line AA in FIG. 1.
本発明において、プリズム部（１）を形成するために用
いられる透明なプラスチックとしては、ポリメチルメタ
クリレート樹脂、ポリペンテン樹脂、ポリカーボネート
樹脂、ポリスチレン樹脂、エポキシ樹脂などが掲げられ
るが、代表的なものはポリメチルメタクリレート樹脂で
アル。In the present invention, examples of the transparent plastic used to form the prism portion (1) include polymethyl methacrylate resin, polypentene resin, polycarbonate resin, polystyrene resin, and epoxy resin. Al with methyl methacrylate resin.
鏡面を看する補強板（２）としては、鉄、アルミニウム
等からなる金属板、ガラス板等が使用される。As the reinforcing plate (2) for viewing the mirror surface, a metal plate made of iron, aluminum, etc., a glass plate, etc. are used.
補強板の鏡面側（３）には、反射膜（４）として真空蒸
着又はスパッタリング等により銀、アルミニウムクロム
等の金属膜を形成する。On the mirror side (3) of the reinforcing plate, a metal film of silver, aluminum, chromium, etc. is formed as a reflective film (4) by vacuum deposition or sputtering.
更に、金属膜には前記透明プラスチックとの接合一体化
を容易ならしめるため、接着剤、例えばエポキシ樹脂を
塗布するのが好ましく、その上に透明プラスチックから
なるプリズム部（１）を射出成形、移送成形、圧縮成形
成いは注型法等により成形する。Furthermore, in order to facilitate the bonding and integration with the transparent plastic, the metal film is preferably coated with an adhesive, such as an epoxy resin, and the prism portion (1) made of transparent plastic is injection molded and transferred onto the metal film. Molding is performed by molding, compression molding, casting, etc.
本発明のミラーの製造方法は次のようなすぐれた効果を
有している。The mirror manufacturing method of the present invention has the following excellent effects.
（１）本発明により得られたミラーはガラスより耐衝撃
性に優れたプラスチックを用いているため、衝突などで
生じる衝撃に耐え、破損する恐れが少なく、人体に対す
る安全性が向上する。(1) Since the mirror obtained by the present invention uses plastic that has better impact resistance than glass, it can withstand impact caused by collisions, has less risk of breakage, and improves safety for the human body.
（２）補強板を用いているため、プラスチックのみで形
成するミラーに比較して、成形時に収縮が小さく変形が
殆んどない。更に、−４０〜＋ＳＯ＜、；の繰返し温度
による反り、波打ち等の変形が殆んどない。従って、寸
法安定性が良いため、光学的に安定でその結果車輌等の
運転に有害な後方視界像の乱れが生じない。(2) Since a reinforcing plate is used, there is less shrinkage during molding and almost no deformation compared to mirrors made only of plastic. Furthermore, there is almost no deformation such as warping or waving due to repeated temperatures of -40 to +SO<, ; Therefore, since the dimensional stability is good, it is optically stable, and as a result, no disturbance of the rear view image that is harmful to the driving of a vehicle or the like occurs.
（３）透明プラスチックからなる平板部またはプリズム
部は通常のプラスチック成形方法によって成形できるの
で、ガラス製のものより大量生産が可能である。(3) Since the flat plate part or prism part made of transparent plastic can be molded by a normal plastic molding method, it can be mass-produced more easily than the one made of glass.
（４）透明プラスチックからなる平板部またはプリズム
部は、ミラー製造工程の最後に形成されるので、透明プ
ラスチックは熱や圧力等による変形、変質を受ける恐れ
がなく、その特性を維持することができる。(4) Since the flat plate portion or prism portion made of transparent plastic is formed at the end of the mirror manufacturing process, the transparent plastic is free from deformation or deterioration due to heat, pressure, etc., and can maintain its properties. .
第１図は本発明で得られたミラーの一例である防眩ミラ
