本犠明はドツトマトリックス形シリアルプリンタ、特に
印字ヘッドの制御に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to dot matrix type serial printers, and more particularly to printhead control.
従来、この種のドツトプリンタは印字へ、ラドの移動速
度が一定となる区間で印字を行ない、従って停止位置か
ら一定速度になるまでの立上ジ距離及び一定速度から減
速して停止するまでの立下り距離が必要であった。また
、一定速度の値が大きければ大きいほど、すなわち印字
速度が高速になるほど立上り距離、立下シ距離は長くな
っていた。Conventionally, this type of dot printer prints in a section where the moving speed of the rad is constant, and therefore the start-up distance from the stop position to the constant speed and the start-up distance from the constant speed to the time when the speed decelerates and stops. Downhill distance was required. Further, the larger the value of the constant speed, that is, the higher the printing speed, the longer the rise distance and fall distance become.
一方、プリンタの小型化への要求を満たすため立上り距
離、立下り距離を少なくするための方式を考町・Mする
必要性が出てきた。On the other hand, in order to meet the demand for smaller printers, it has become necessary to consider methods for reducing the rise and fall distances.
本発明は印字のための移動速度を高速、低速2通り備え
、最左端または最右端で印字を行なわない時は、初めか
ら高速印字速度まで立上げて印字を行ない、逆に最左端
または最右端で印字を行なう時は、停止位置より低速印
字速度まで立上げ数文字印字して一旦停止し後戻りし再
び高速印字速度まで立上げ続きの印字を行ない、残り数
文字の所で一旦停止し、後戻りし低速印字速度で残りの
文字を印字することにより、高速印字機能と短い立上り
、立下り距離の二つの機能の両立が可能な装置を提供す
るものである。The present invention has two moving speeds for printing, high speed and low speed, and when printing is not performed at the leftmost or rightmost end, the printing speed is increased from the beginning to the high speed printing speed, and vice versa. When printing, start from the stop position to a low printing speed, print a few characters, stop once, go back, start up to a high printing speed again, continue printing, stop once with a few characters left, and go back. By printing the remaining characters at a low printing speed, the present invention provides an apparatus capable of achieving both a high-speed printing function and short rise and fall distances.
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、本発明の一実施例において、1行
メモリ1は1行分(136桁)の印字情報を記憶する。Referring to FIG. 1, in one embodiment of the present invention, a one-line memory 1 stores one line (136 columns) of print information.
横送り制御部2は、横送シ速度を制御する。印字におけ
る横送り速度は2通りあり各々高速印字速度、低速印字
速度と呼ぶ、両方の印字・氷度に対し各々立上り制御、
立下り制御がありこれらは停止→高速用立上り→高速印
字速度→高速用立下ジ→停止(高速プロフィール)ある
いは、停止→低速用立上り→低速印字速度→低速用立下
り→停止(低速プロフィ−含)というように制御される
。The traverse feed control section 2 controls the traverse feed speed. There are two types of horizontal feed speeds for printing, called high printing speed and low printing speed.
There is fall control, and these are stop → high speed rise → high speed printing speed → high speed fall → stop (high speed profile) or stop → low speed rise → low speed printing speed → low speed fall → stop (low speed profile) (including).
1行メモリ1の印字情報に第1桁での印字データがない
場合は高速プロフィールに従って制御される。これは従
来方式と同じである。逆に第1桁での印字データがある
場合は、第1桁の文字だけを低速プロフィールで印字し
、一旦後戻、1して最初の停止位置へ印字ヘッドを運び
、次に高速プロフィールにより、第2桁以降の印字を行
なう。If the print information in the one-line memory 1 does not include print data for the first digit, control is performed according to the high-speed profile. This is the same as the conventional method. On the other hand, if there is print data for the first digit, print only the first digit character with the low-speed profile, then go backwards, turn 1, and bring the print head to the first stop position, then use the high-speed profile. Print the second and subsequent digits.
第136桁での制御方式もこれと同様である。The control method for the 136th digit is also similar to this.

し、第2桁以降の印字を行なう。Next, the operation will be explained with reference to FIG. l from 1st digit
The case where printing is performed in the forward direction on Kj is shown. In the conventional method, a rising distance of two characters is required (indicated by a broken line in the figure).In the method according to the present invention (indicated by a solid line in the figure), a rising distance of one character is sufficient. The control procedure is to first run up for one character from the stop position, print only 41 digits (print Ai at step), immediately decelerate,
It stops between the 2nd and 3rd digit. Move back to the initial stop position on the 2nd line. Thirdly, the printer moves two characters from the stop position and prints the second and subsequent digits.
