本発明は電子写真式プリンタの光ヘッドに関し、特に液
晶シャッタヘッドに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical head for an electrophotographic printer, and more particularly to a liquid crystal shutter head.
従来、この種の電子写真式プリンタの光ヘッドは温度制
御機構を有していなかった。Conventionally, the optical head of this type of electrophotographic printer has not had a temperature control mechanism.

温度上昇による動作不良、螢光灯の低温による光量不足
となり、結果として印字品質の低下が見られるという欠
点がある。The optical head of the conventional electrophotographic printer mentioned above did not have a temperature control mechanism, so the temperature rise in the liquid crystal shutter array caused malfunction, and the low temperature of the fluorescent lamp led to insufficient light intensity, resulting in a decline in print quality. The disadvantage is that it can be seen.
本発明の目的は前記課題を解決した電子写真式プリンタ
の光ヘッドを提供することにある。An object of the present invention is to provide an optical head for an electrophotographic printer that solves the above problems.

子冷却器とを有するものである。(Means for Solving the Problems) In order to achieve the above object, the optical head of an electrophotographic printer according to the present invention includes a light source and a light source that closely contacts the light source in an electrophotographic printer that uses a liquid crystal shutter as an optical head. a liquid crystal shutter array, a fixed plate holding the liquid crystal shutter array, and an electronic cooler having a heat generating surface in contact with the reflective plate and a cooling surface thereof in contact with the fixed plate. It is something.
以下、本発明の一実施例を図により説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
第１図は本発明の一実施例を示す構成図である。FIG. 1 is a block diagram showing an embodiment of the present invention.

are attached in close contact with each other, and a liquid crystal shutter array 6 is held and disposed on a fixed plate 5 in a position in front of the fluorescent lamp 4. Further, the heat generating surface of the electronic cooler 2 is brought into contact with the reflecting plate 3, and the cooling surface thereof is brought into contact with the fixed plate 5. 1 is a power source that drives the electronic cooler 2;

。Therefore, according to the present invention, since the liquid crystal shutter array 6 is cooled by the electronic cooler 2, malfunctions due to an increase in the temperature of the liquid crystal shutter array 6 do not occur.
Furthermore, since the fluorescent lamp 4 is heated through the reflector plate 3, it is possible to solve the problem of insufficient light quantity due to the low temperature of the fluorescent lamp 4.
