本発明はカールソンプロセス手法を用いた液晶電子写真
プリンタに関し、特にその除電装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a liquid crystal electrophotographic printer using the Carlson process technique, and particularly to a static eliminator therefor.
従来この種の液晶電子写真プリンタは、光導電層を有す
る回転可能な感光体のまわりに光導電層を一様に帯電さ
せる帯電器と、光源を内蔵する液晶ヘッドと、感光体に
付着したトナーを紙に転写する転写チャージャと、感光
体に残ったトナーをかき落とすクリーナと、光導電層の
電荷を一様に除去する除去装置の光源とをそれぞれ独立
して配置していた。Conventionally, this type of liquid crystal electrophotographic printer has a charger that uniformly charges the photoconductive layer around a rotatable photoconductor having a photoconductive layer, a liquid crystal head with a built-in light source, and toner attached to the photoconductor. A transfer charger for transferring toner onto paper, a cleaner for scraping off toner remaining on the photoreceptor, and a light source for a removing device for uniformly removing the charge on the photoconductive layer were each arranged independently.
上述した従来の液晶電子写真プリンタでは液晶ヘッド用
光源と除電装置用光源をそれぞれ独立して２つもたなけ
ればならないという欠点がある。The above-mentioned conventional liquid crystal electrophotographic printer has the disadvantage that it must have two independent light sources for the liquid crystal head and two light sources for the static eliminator.
本発明の液晶電子写真プリンタでは、液晶ヘッド光源か
らの光の一部を除電部まで伝達するためのレンズおよび
ミラー等の光伝達手段を有している。The liquid crystal electrophotographic printer of the present invention includes a light transmitting means such as a lens and a mirror for transmitting part of the light from the liquid crystal head light source to the static eliminator.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は、本発明の一実施例の感光ドラムを中心とした

６、感光体１の帯電を除去する除電部７を所定の位置に
配しである。FIG. 1 is a vertical cross-sectional view centered on a photosensitive drum according to an embodiment of the present invention. ``A corona charger 2 that uniformly charges the photosensitive drum 1 around the photosensitive drum 1 having a photoconductive layer;
A liquid crystal head 3 that forms an exposed latent image on the photosensitive drum 1, a developer 4 that attaches toner to the latent image formed on the photosensitive drum 1, a transfer charger that transfers the toner attached to the photosensitive drum 1 onto paper, 5, and a residual image. A cleaning device 6 for removing toner and a static eliminator 7 for removing static electricity from the photoreceptor 1 are arranged at predetermined positions.
液晶ヘッド３の光源８はハウジング９に収められている

７まで伝達することにより除電用光源として利用する。The light source 8 of the liquid crystal head 3 is housed in a housing 9. A lens 10 is attached to the housing 9 to make the light parallel, and a part of the light emitted from the light source 8 passes through the lens 10. The parallel light is taken out from the housing 9 and transmitted to the static eliminator 7 via the mirror 11 placed at a predetermined position, thereby being used as a light source for static elimination.
液晶ヘッド光源８から除電部７までの光の伝達経路は１
２のようになり除電用光源として利用できることがわか
る。The light transmission path from the liquid crystal head light source 8 to the static eliminator 7 is 1.
2, it can be seen that it can be used as a light source for static elimination.
以上説明したように本発明は液晶ヘッドの光源の光の一
部を除電装置の光源に利用することにより、除電装置の
光源を独立して持たなくてもよいという効果がある。As described above, the present invention has the advantage that by utilizing a portion of the light from the light source of the liquid crystal head as the light source of the static eliminator, the static eliminator does not need to have an independent light source.
