本発明は、電子写真系プリンタの用紙走行ガイドに関し
、特にその用紙ガイドの保持機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper running guide for an electrophotographic printer, and particularly to a holding mechanism for the paper guide.
従来、この種の電子写真系プリンタの用紙走行部におけ
る用紙ガイドは、材質に６６ナイロン（静電気対策）を
用い、第２図の如く装置ベース１１に固定ネジ１２によ
り用紙ガイド１３の４カ所をネジ止め固定していた。Conventionally, the paper guide in the paper running section of this type of electrophotographic printer has been made of 66 nylon (to prevent static electricity), and the paper guide 13 has four screws attached to the device base 11 with fixing screws 12 as shown in FIG. It was fixed in place.

激な温度変化等により、用紙ガイドが変形し、用紙走行
が不安定となり高印字品質を保持出来なくなる欠点があ
る。The paper guide of the conventional electrophotographic printer mentioned above was simply fixed with four screws to the device base, so sudden changes in temperature could cause the paper guide to deform, making the paper run unstable and resulting in high printouts. There is a drawback that quality cannot be maintained.
本発明の電子写真系プリンタの用紙走行ガイドは、１端
がベースに固定され他端が熱変形防止スライド機構によ
り熱膨張による変形を吸収可能に保持されたことを特徴
とする。The paper running guide for an electrophotographic printer according to the present invention is characterized in that one end is fixed to a base and the other end is held by a thermal deformation prevention slide mechanism so as to absorb deformation due to thermal expansion.
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斜視図である。FIG. 1 is a perspective view of an embodiment of the present invention.

ギャップ９を保つ櫟な寸法で、かつＸ−Ｙ方向には０．
５〜１ｍｍのスキマ１０を有した状態でスライド溝５に
挿入されており、用紙ガイド１の他端を保持している。The paper guide 1 guides the printing paper 2 traveling in the direction of the arrow, and is fixed at two places on one end to the device base 3 with fixing screws 4, and a slide groove 5 is formed at the 2fJ location of the other vehicle. ing. A slide holding plate 6 provided for the purpose of holding the other end of the paper guide 1 is fixed to the device base 3 at two locations with fixing screws 7. or,
The sliding portion 8 of the holding plate 6 is moved in the Z direction (paper guide 1
It has a rectangular dimension that maintains a gap 9 of 0.2 to 0.5 mm at room temperature in the thickness direction), and 0.2 to 0.5 mm in the X-Y direction.
It is inserted into the slide groove 5 with a gap 10 of 5 to 1 mm, and holds the other end of the paper guide 1.

用紙ガイド１の印字用紙スライド上面は安定した状態で
ある。By providing a thermal deformation prevention sliding mechanism that absorbs changes due to thermal expansion in the X-Y-Z axis of the paper guide 1 through the gap 9 and the clearance 10 when a temperature change occurs, the printing paper slide of the paper guide 1 is always maintained. The top surface is in a stable state.
以上説明した様に本発明の電子写真系プリンタの用紙走
行ガイドは、熱変形防止スライド機構を有する事により
、プリンタの使用環境の変化にかかわらず安定した用紙
走行を保持出来、常に一定の高印字品質を保持する効果
がある。As explained above, the paper running guide of the electrophotographic printer of the present invention has a slide mechanism to prevent thermal deformation, so that it can maintain stable paper running regardless of changes in the usage environment of the printer, and can always maintain a constant high print quality. It has the effect of maintaining quality.
