本発明は、印字品質の良好なプリンターに関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printer with good print quality.
一般にプリンターにおいては、記録紙の平滑度は印字品
質に大きな影譬を４える。In general, in printers, the smoothness of recording paper has a large impact on print quality.
例えば準転写プリンターにおいて平滑度の低い記録紙に
印字を行なう場合、サーマルヘッドによって加熱され溶

する。第１図は従来のプリンターにおける転写状態を示

有し、この表向にサーマルヘッド２によりインクリボン

しインクリボン３のインク６−１を溶融して記録紙１に
転写させる。しかしながら記録紙１の表−の凹凸により
、本来ａ及びｄの巾にわたって転写されるべきインクが
融の様に途切れたり１またＣの巾にわたって所定の厚み
を持って転写されるべきインクが図の様に薄かったりす
る現象が発生する。For example, when printing on recording paper with low smoothness using a semi-transfer printer, the ink heated and melted by the thermal head is normally transferred to the convex portions of the recording paper surface, but is not transferred to the concave portions ( , the print quality deteriorates considerably. Figure 1 shows the transfer state in a conventional printer. The recording paper 1tji! has a low smoothness and has uneven surfaces. The ribbon 6 is pressed.Thermal head 2Fi generates heat at a predetermined position, melts the ink 6-1 on the ink ribbon 3, and transfers it to the recording paper 1.However, due to the unevenness of the front side of the recording paper 1, the original a and d Phenomena occur in which the ink that should be transferred across the width is interrupted like melting, or the ink that should be transferred with a predetermined thickness over the width 1 or C is thin as shown in the figure.
この結果、印字一度の低下、文字の字欠け、ムラが発生
し、総じて印字品質が低下する。As a result, the quality of printing decreases, characters are missing, and unevenness occurs, resulting in an overall decrease in print quality.
そこで従来においてｄ’ｓ インクリボンのインク担持
量を増大させたり〜サーマルヘッドの加熱時間を長くし

十分インクが転写されるような工夫がなされた。しかし

合に社、インクの転写量が増大し、文字のカブリ、ツブ
シを生じる。また、サーマルヘッドの加熱時間を長くし
た場合、ヒートすイクルが長（なるため高速印字に対す
る陣害となる。Therefore, in the past, measures were taken to increase the amount of ink carried by the d's ink ribbon, increase the heating time of the thermal head, and increase the amount of ink to be transferred to the concave sK. . However, in this case, when the smoothness of the recording paper used is high, the amount of ink transferred increases, causing fogging and blurring of characters. Furthermore, if the heating time of the thermal head is increased, the heating cycle becomes longer (which becomes a disadvantage to high-speed printing).
また、印字後に１圧力、熱定着を行なう方法もあるが、
これでもや鉱シ記鎌紙の平滑度が高く、転写が十分性な
われた場合に社、かえって転写されたインクを押し広げ
１文字のカプリ、ツブシをもたらす。There is also a method of performing heat fixing under one pressure after printing.
Even with this, the smoothness of the ink paper is high, and if the transfer is not sufficient, the transferred ink will be spread out and a single character capri or tsubushi will be produced.
本発明は、上記欠点を除去するもので、記―紙を印字部
前後で加圧する事によって記録紙の平滑度を向上させ、
使用する記録紙の平滑度によらず常に良好な印字品負の
得られるプリンターを提供することを目的とする。以下
実施例の図面を基に本発明の詳細な説明を行なう。The present invention aims to eliminate the above-mentioned drawbacks, and improves the smoothness of the recording paper by applying pressure to the recording paper before and after the printing section.
An object of the present invention is to provide a printer that can always produce good print quality regardless of the smoothness of recording paper used. The present invention will be described in detail below based on drawings of embodiments.

給する。4 is an inkliden which heats the image in cooperation with the pinch O-95 on the platen. Reference numerals 9 and 10 denote pressure rollers that apply pressure to the recording paper 6 to smooth the recording paper, and constitute a recording paper smoothing device. Each roller 9, 1° is located at the front and rear of the printing section, that is, the platen 1. : Tosu-! It is arranged on the recording paper supply side with respect to the abutting part of the head 7, and always supplies smoothed recording paper to the printing part.
