【発明の詳細な説明】 〔産業上の利用分野〕 本発明はプリンタ装置のキャリア上に設けられた用紙ガ
イド部材と印字面に印字用紙を圧接するためのローラ形
状に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper guide member provided on a carrier of a printer device and a roller shape for pressing a printing paper against a printing surface.
従来この種の用紙ガイド部材と印字面に用紙を圧接する
ためのローラは円筒形状となっており圧接シャフト上に
回転自在に保持された構造となっていた。Conventionally, this type of paper guide member and a roller for pressing the paper against the printing surface have a cylindrical shape and are rotatably held on a pressing shaft.
前述した、従来の用紙ガイド部材と印字面に用紙を圧接
するための圧接ローラは外形が円筒形状となっており、
シャフト上に回転自在に保持されていた。このため用紙
両端エッジ部が印字面と逆方向にカールしている場合は
印字面と用紙ガイド部材の間隙を通過した用紙が前記印
字面と圧接ローラの間を通過する場合用紙のエッジ部が
スムースに圧接ローラ部に噛み込まず用紙ジャムの原因
となる欠点を有していた。As described above, the conventional paper guide member and the press contact roller for press contacting the paper with the printing surface have a cylindrical outer shape,
It was rotatably held on the shaft. Therefore, when both edge portions of the paper are curled in the direction opposite to the printing surface, when the paper passing through the gap between the printing surface and the paper guide member passes between the printing surface and the pressure roller, the edge portion of the paper is smooth. In addition, it has a drawback that it does not get caught in the pressing roller portion and causes a paper jam.

形成されたことを特徴とする用紙案内構造が得られる。[Means for Solving the Problems] According to the present invention, a paper guide member having the same shape is provided on a carrier in parallel with a print surface, and a print head tip portion and an ink ribbon are provided near the center of the paper guide member. Has two windows that can be exposed to the printing surface, and has two pressing rollers for pressing the printing surface that has passed through the gap between the printing surface and the paper guide member to the printing surface, and the two pressing rollers are the windows. It is fixed on the same rotation axis parallel to the platen around which the printing paper is wound, and is formed in a tapered shape so that the outer diameter gradually decreases from the vicinity of the facing end faces near the center toward the other end. A paper guide structure is obtained.
次に本発明の実施例について図面を参照して説明する。 Next, embodiments of the present invention will be described with reference to the drawings.
第１図を参照すると、プラテン１はフレーム（図示せ

用紙ガイド３を搭載したキャリアフレーム４をプラテン
１と平行に左右に移動可能に案内すべく設けられた案内
軸5a,5bの両端を固定保持した構成となっている。Referring to FIG. 1, a platen 1 is rotatably held by a frame (not shown), and a carrier frame 4 having a print head 2 and a paper guide 3 mounted thereon is guided so as to be movable left and right in parallel with the platen 1. Both ends of the guide shafts 5a, 5b provided to do so are fixed and held.

ドル形状の圧接ローラ7,8を２個が対称に配置された構
造で前記圧接シャフト６は、スプリング張力（図示せ
ず）により常時プラテン１方向に圧接されている。Further, the pressure contact shaft 6 is parallel to the platen 1 on the platen 1, and two spundle-shaped pressure contact rollers 7 and 8 rotatably held on the pressure contact shaft are symmetrically arranged. It is constantly pressed against the platen 1 by spring tension (not shown).
動作を説明すると、用紙９はキャリアフレーム４上の用
紙ガイド３とプラテン１の間を通過し、用紙ガイド３に

の間を通過する。Describing the operation, the sheet 9 passes between the sheet guide 3 on the carrier frame 4 and the platen 1 and is guided to the pressure contact rollers 7 and 8 by the sheet guide 3 and the platen 1 and the pressure contact rollers 7 and 8.

る。According to the present invention having the above-described structure, the printing paper passing through the gap between the platen and the paper guide member is first pressed by the paper guide at the portion near the center of the paper even when the paper edge is curled in the direction opposite to the printing surface. Since the roller is bitten and the outer side is sequentially called by the pressure roller, the sheet can be wound around the platen irrespective of the edge curl of the sheet, so that there is an effect that the sheet jam can be minimized.
