Description
【発明の詳細な説明】 〈産業上の利用分野） 本発明は記録装置に用いられる紙搬送装置に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a paper conveyance device used in a recording device.
（従来技術）
複写機やファクシミリあるいはプリンタなどの記録装置
においては、記録用紙あるいは原稿を搬送する紙搬送装
置か用いられている。(Prior Art) Recording devices such as copying machines, facsimile machines, and printers use paper conveying devices for conveying recording paper or original documents.
従来の紙搬送装置は、ローラ対すなわち駆動ローラとそ
れに圧着する従動ローラを用いてローラ間に紙を挾みロ
ーラを回転させて紙を送るか、またはベルトとローラを
組合せてその両者の間に紙を挟んで搬送するのが一般的
である。Conventional paper conveyance devices use a pair of rollers, that is, a drive roller and a driven roller that presses against the drive roller, to sandwich the paper between the rollers and rotate the rollers to feed the paper, or to combine a belt and a roller to convey the paper between the two. It is common to convey paper by sandwiching it between them.
しかしながら、ローラ対による搬送は、給紙の信頼度は
高いかローラのニップ方向の空間か限定された場合つま
り搬送方向に対して直角の方向にスペースが取れない場
合は、設置が難しくなる。However, conveyance by a pair of rollers is difficult to install if the reliability of paper feeding is high or if the space in the nip direction of the rollers is limited, that is, if there is no space available in the direction perpendicular to the conveyance direction.
またベルト搬送は、ベルトを懸架するための部材か必要
になるので、どうしても部品点数が増加し狭く短いスペ
ースに設置することはできない。Furthermore, belt conveyance requires a member for suspending the belt, which inevitably increases the number of parts and cannot be installed in a narrow and short space.
（発明の目的および構成）
本発明は上記の点にかんがみてなされたちのて、狭いス
ペースでも設置てきろ紙搬送装置を提供することを目的
とする。(Object and Structure of the Invention) The present invention has been made in view of the above points, and an object of the present invention is to provide a filter paper conveying device that can be installed even in a narrow space.

。In order to achieve this purpose, a guide member having a plurality of protrusions in the paper feeding direction is provided, and one or more conveyance rollers provided opposite to the side of the guide member on which the protrusions are provided.
The width of the conveying roller is narrower than the installation interval of the protrusions, and the conveying roller is placed between adjacent protrusions, and the conveying roller is placed on the guide member side of the conveying roller. The roller surface is configured to be on the same plane as the apex of the protrusion or to be located closer to the guide member than the apex of the protrusion.
（実施例） 以ド本発明を図面に基づいて説明する。(Example) The present invention will now be explained based on the drawings.
第１図は本発明による紙搬送装置の一実施例を示す断面
図であり、第２図は第１図の装置を矢印へ方向から見た
図である。この装ごは、たとえば複写機の給紙カセット

設置される。FIG. 1 is a sectional view showing an embodiment of a paper conveying device according to the present invention, and FIG. 2 is a view of the device shown in FIG. 1 as viewed from the direction of the arrow. This mount is installed, for example, as part of a paper feeding device in a conveyance path between a paper feeding cassette and a photosensitive drum of a copying machine.
図において、ｌは給紙方向に複数の突条２を設けたガイ
ド部材、３はガイド部材ｌの突条２を設けた側に対向し
て設けられた搬送ローラである。In the figure, l is a guide member provided with a plurality of protrusions 2 in the paper feeding direction, and 3 is a conveyance roller provided opposite to the side of the guide member l on which the protrusions 2 are provided.
搬送ローラ３は回転軸４を介してモータなどの駆動手段
（図示せず）によって駆動される。また５はガイド部材
ｌの下方に設けられたガイド板である。The conveying roller 3 is driven by a driving means (not shown) such as a motor via a rotating shaft 4. Further, 5 is a guide plate provided below the guide member l.
搬送ローラ３の幅は突条１の設置間隔より狭くなってお
り、搬送ローラ３は突条と突条の間に位置するように配
置されている。また搬送ローラ３のガイド部材ｌ側のロ
ーラ面３ａは突条２の頂点２ａよりガイド部材１寄りに
位ｔしている。The width of the conveyance roller 3 is narrower than the installation interval of the protrusions 1, and the conveyance roller 3 is arranged so as to be located between the protrusions. Further, the roller surface 3a of the conveyance roller 3 on the guide member l side is located closer to the guide member 1 than the apex 2a of the protrusion 2.
記録紙Ｐはガイド部材１とガイド板５との間に挿入され
る。記録紙Ｐは図のように変形されながら、その復元力
（紙のＩＩりにより搬送ローラ３の表面に押し付けられ
、ローラ面との間で生じる摩擦力により搬送される。Recording paper P is inserted between guide member 1 and guide plate 5. While being deformed as shown in the figure, the recording paper P is pressed against the surface of the transport roller 3 by its restoring force (the paper's curvature), and is transported by the frictional force generated between it and the roller surface.
以−にのようにすれば、突条な有するガイド部材および
搬送ローラというごく簡単な構造になり、したがって装
置の占有スペースも小さくて済む。By doing the above, the structure becomes very simple, consisting of a guide member having a protruding strip and a conveying roller, and therefore the space occupied by the apparatus can be reduced.

までもない。In the embodiment described in 2, an example was shown in which the paper conveying device of the present invention was disposed in the paper feeding section. However, the arrangement position n is not particularly limited, and may be installed on another conveyance path such as the paper ejection section. Needless to say, it can be used for.
