Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は印字装置における紙のタルミの除去方法に関
する。Description: FIELD OF THE INVENTION The present invention relates to a method for removing paper thinning in a printing apparatus.
（従来技術） プッシュトラクタにより給紙を行なう印字装置では、
給紙中に紙経路内で発生する紙のタルミをプッシュトラ
クタよりも速い送り速度を有する排紙ローラによって取
り除くようにしている。(Prior art) In a printing device that feeds paper by a push tractor,
The paper jam generated in the paper path during paper feeding is removed by a paper discharge roller having a faster feeding speed than a push tractor.
このため、この種の方法では、排紙ローラの速い送り

にしたものである。(Means for Solving the Problems) That is, according to the present invention, as a method of removing paper pulp of a printing apparatus for achieving the above object, first, a push tractor is rotated forward so that a continuous paper can be transferred in the paper transport direction of a recording head. The paper is fed to a position slightly protruding from this paper holding member with respect to the paper holding member arranged on the side, and then the continuous paper is advanced and retracted by rotating the push tractor forward and backward by an arbitrary set amount, respectively. Then, the continuous paper is fed by a platen from the retracted position.
（実施例） そこで以下に本発明の実施例について説明する。Embodiment An embodiment of the present invention will be described below.
はじめに、この紙送り方法が適用されるプリンタの概
要構成を第１図をもとに説明する。First, a schematic configuration of a printer to which the paper feeding method is applied will be described with reference to FIG.

２が配設されている。On the upstream side of the platen 1 in the paper feeding direction, a push tractor 2 for executing paper feeding of the continuous paper 9, a paper guide plate 6 for guiding the fed continuous paper 9 to the platen 1,
A paper holding plate 4 for pressing the continuous paper 9 against the peripheral surface of the platen 1 with a weak force is disposed in order, and a paper discharge contacting / separating from the peripheral surface of the platen 1 is provided on the lower side of the platen 1 in the paper feeding direction. A roller 2 is provided.
上記したプッシュトラクタ２は、用紙９の送りと戻し

ジ７上に搭載された印字ヘッドを示している。The above-mentioned push tractor 2 is configured to be rotatable forward and backward so as to execute feeding and returning of the paper 9, and the paper discharge roller 2 is configured to contact the peripheral surface of the platen 1 when the continuous paper 9 is discharged. ing. Note that reference numeral 8 in the drawing denotes a print head mounted on the carriage 7.
つぎに、第２図乃至第４図をもとに連続用紙９のタル
ミを除く方法について説明する。Next, a method of removing the thickening of the continuous paper 9 will be described with reference to FIGS.
はじめに、プッシュトラクタ２を正転させて、先端が
紙押え板４の押圧部より若干突出した点Ａ、つまり頭出
しの点まで、連続用紙９を正転しているプラテン１面上
に送り出す。First, the push tractor 2 is rotated forward, and the continuous paper 9 is sent out onto the platen 1 that is rotating forward to a point A where the leading end slightly protrudes from the pressing portion of the paper holding plate 4, that is, a cue point.
この送り出しの操作によって、紙押え板４による摩擦
抵抗を受けた連続用紙９は、第２図に示したように、紙
押え板４に到る経路中で紙にタルミが生じる。As a result of this feeding operation, the continuous paper 9 subjected to the frictional resistance by the paper presser plate 4 causes the paper to be thickened in the path reaching the paper presser plate 4 as shown in FIG.
つぎにこの状態から、プッシュトラクタ５をさらに正
転させ、5mm乃至30mm程度の範囲内で任意の設定される
量だけ連続用紙９を前進させ、ついで、プラテン１とと
もに同じ回転数だけプッシュトラクタ９を逆転させて、
連続用紙９を後退させる。Next, from this state, the push tractor 5 is further rotated forward, the continuous paper 9 is advanced by an arbitrary set amount within a range of about 5 mm to 30 mm, and then the push tractor 9 is rotated with the platen 1 by the same rotation speed. Reverse it,
The continuous paper 9 is retracted.
この一定量の送り出しは、紙にタルミが生じている状
態で行われるが、これに続く一定量の引き戻しにおい

戻しにより、連続用紙９の先端は、第３図に示したよう
に、紙のタルミの分、もとの突き出し位置Ａより送り側
にΔＡだけずれて戻る。The feeding of the fixed amount is performed in a state in which the paper is thickened. However, in the subsequent retraction of the fixed amount, the continuous paper 9 is fed in a direction opposite to the direction of the paper holding plate 4. The paper is pulled back by the push tractor 2 so as to slide on the platen 1 while receiving the strong resistance of the paper holding plate 4. It will be in the state of being put. Therefore, by this series of feeding and pulling back, the leading end of the continuous paper sheet 9 is shifted back by ΔA from the original protruding position A to the feeding side by the paper thickness as shown in FIG.
したがって、この状態から最後に、プラテン１により
連続用紙９を前進させるとともに、所要のタイミングを
置いて印字を開始させる。Accordingly, from this state, finally, the continuous paper 9 is advanced by the platen 1 and printing is started at a required timing.

９を順に排出する。By this operation, the platen 1 whose peripheral speed is set to be several percent higher than that of the push tractor 2 feeds the continuous paper 9 from the position of ΔA to the recording head 8 in a state where there is no paper thinning. When the printing operation is started at the timing of, the writing of the recording with a slight top margin can be performed, and thereafter, the paper pressing roller 3 is pressed against the peripheral surface of the platen 1 to complete the recording and writing. The continuous paper 9 is sequentially discharged.

きる。(Effects) As described above, according to the present invention, first, the push tractor is rotated forward to feed the continuous paper to a position immediately before the recording head, and then the push tractor is rotated forward and backward by an arbitrary amount to continuously rotate the continuous paper. Is moved forward and backward, so that the fixed amount of forward and backward movement makes it possible to remove paper jam without changing the position of the leading edge of the continuous paper.
Accurate recording and writing can be performed while continuously feeding continuous paper without causing a deviation in the line pitch.
