Description

本発明はドット印字ハンマによりドットマトリクス形式により印刷を行うドットラインプリンタの印刷制御方法に関するものである。   The present invention relates to a printing control method for a dot line printer that performs printing in a dot matrix format using a dot printing hammer.

図5、図6により印刷機構を説明する。印刷行と垂直方向に所定ピッチでN列に並べられた印字ハンマ9を1単位とし、該印字ハンマ9の複数個を印刷行方向に並べて配置したハンマモジュール17と該ハンマモジュール17を印刷行方向に複数個実装したハンマ機構部18はシャトル機構部19に取り付けられ、印刷行方向に往復運動(左から右、右から左をそれぞれ1ストロークとし、1往復で2ストロークとする)を行う。印字ハンマ9の印字力を支持するプラテン20は、印刷用紙16及びインクリボン15を介してハンマ機構部18に対向して配置されている。
ここで用いるハンマ機構部18はスプリングチャージ方式と呼ばれるものであり、ヨーク12、マグネット11、フロントヨーク10によって磁気回路を構成している。ハンマ機構部18を駆動していない間は、印字ハンマ9は所定の撓み量をもってヨーク12に磁気吸引された状態にあり、ヨーク12に取り付けられた釈放用電磁コイル13(以下単にコイルという)に磁気吸引力を打ち消す方向に所定パルス幅駆動電流(以下駆動電流という)を流して、印字ハンマ9の撓みを解放し、インクリボン15を介して印刷用紙16を打撃することによって1ストロークでNドットラインを印刷する。
以上のようなドットラインプリンタにおいて、1ストローク内の全印刷ドット数が多いと、電源の消費エネルギーが瞬間的に大きくなり、ハンマ機構部の電源電圧が低下するため、印刷ドット数が少ない時の印字ハンマの駆動電流に対して、駆動電流が低下してしまう。
したがってマグネットの磁気吸引力を打ち消すために十分な釈放電流が供給できず、結果として印刷ドットが抜けてしまう等の印刷不具合が発生してしまう。また、1ストローク内の全印刷ドット数が多いと、必然的に隣接する印字ハンマの同時駆動数が多くなる。これにより印字ハンマを保持する磁気吸引力が大きくなるという磁気干渉の影響が大きくなり、結果として印刷ドットが抜けてしまう印刷不具合が発生してしまう。
上記の印刷品質が低下するという問題を解決するため、印刷前に1ストロークで印刷する全印刷ドット数をカウントし、カウント数が規定値以上になった場合は印刷データを2ストローク以上に分けて印刷する打ち分け印刷を実行し、1ストローク内の印刷ドット数を制限し電源電圧低下による印刷品質の低下を抑制するものがある。(例えば、特許文献1)
また、印刷前に1ストロークで印刷する全印刷ドット数を印刷行方向に複数ブロックに分割し、各ブロックの印刷ドット数をカウントし、カウント数が規定値以上になったブロックの印字ハンマに対して磁気干渉によって大きくなった磁気吸引力を消磁し、印字ハンマを釈放するために印字ハンマの駆動電流の電流積が大きくなる方向に電流値を変更し、印刷品質の低下を抑制していた。(例えば、特許文献2)
The printing mechanism will be described with reference to FIGS. A printing hammer 9 arranged in N columns at a predetermined pitch in the vertical direction with respect to the printing line is regarded as one unit, and a hammer module 17 in which a plurality of printing hammers 9 are arranged in the printing line direction and the hammer module 17 are arranged in the printing line direction. A plurality of hammer mechanism parts 18 mounted on the shuttle mechanism part 19 are attached to the shuttle mechanism part 19 and reciprocate in the printing line direction (left to right and right to left are one stroke each, and one reciprocation is two strokes). The platen 20 that supports the printing force of the printing hammer 9 is disposed to face the hammer mechanism 18 via the printing paper 16 and the ink ribbon 15.
The hammer mechanism 18 used here is called a spring charge system, and the yoke 12, magnet 11, and front yoke 10 constitute a magnetic circuit. While the hammer mechanism 18 is not driven, the printing hammer 9 is magnetically attracted to the yoke 12 with a predetermined amount of deflection, and is applied to a release electromagnetic coil 13 (hereinafter simply referred to as a coil) attached to the yoke 12. A predetermined pulse width drive current (hereinafter referred to as drive current) is passed in the direction to cancel the magnetic attractive force, the flexure of the print hammer 9 is released, and the print paper 16 is struck through the ink ribbon 15 so that N dots are generated in one stroke. Print the line.
In the dot line printer as described above, if the total number of printing dots in one stroke is large, the power consumption energy increases momentarily, and the power supply voltage of the hammer mechanism decreases. The drive current decreases with respect to the print hammer drive current.
Therefore, a sufficient release current cannot be supplied to cancel out the magnetic attractive force of the magnet, and as a result, a printing defect such as a print dot missing occurs. In addition, if the total number of printing dots in one stroke is large, the number of simultaneously driven adjacent printing hammers inevitably increases. As a result, the influence of magnetic interference that the magnetic attraction force for holding the printing hammer increases is increased, and as a result, a printing defect in which printing dots are lost occurs.
In order to solve the above-mentioned problem that the print quality deteriorates, the total number of print dots printed in one stroke is counted before printing, and if the count exceeds the specified value, the print data is divided into two or more strokes. There is a type that performs print-by-print printing and limits the number of print dots in one stroke to suppress a drop in print quality due to a drop in power supply voltage. (For example, Patent Document 1)
Also, before printing, the total number of dots printed in one stroke is divided into multiple blocks in the print line direction, and the number of dots printed in each block is counted. In order to demagnetize the magnetic attraction force increased due to magnetic interference and release the print hammer, the current value is changed in a direction in which the current product of the drive current of the print hammer increases, thereby suppressing the deterioration in print quality. (For example, Patent Document 2)

しかしながら従来の技術では、1ストローク内の全印刷ドット数或いは各ブロック毎の印刷ドット数が少なく且つ、印刷ドットが印刷範囲の局部的に集中する印刷、或いは印刷ドットが特定の隣接する印字ハンマに集中する印刷の場合においても、隣接する印字ハンマ間で印字ハンマの同時駆動による磁気干渉の影響を受け印刷品質が低下する傾向がある。
それを回避する従来手段として、打ち分け印刷或いは印字ハンマの駆動電流値を変更する手段を用いるが、打ち分け印刷を実行すると少ない印刷ドット数で印刷の実行速度が落ちてしまう。
図7にN=12列配列のハンマスプリングの概略図を示す。
印刷行と垂直方向にN列(例えばN=12)に配列している印字ハンマは、隣接するコアからの磁束の回り込みの差により、N列各々において釈放後の印字ハンマの動作速度に差が生じ、結果として印刷濃度に影響を及ぼす印字力及び印字ハンマの釈放、印刷、吸着の一連の動作に掛かる反応時間(リピータビリティ)がN列各々で不均一になっており、磁気干渉の影響にも差が生じる。
図8にN=12列配列の各列の印字ハンマの印字力を示す。前記各ブロック毎に印字ハンマの駆動電流の電流積が大きくなる方向に電流値を変更した場合でも、各ブロック内のN列各々の印字ハンマの印字力が不均一のままとなる。したがって一様な電流値の変更では印刷品質、特に印刷濃度に差が生じてしまい、結果として印刷濃淡等の印刷不具合が発生してしまう。更に一様な電流値の変更では、変更する必要の無い印字ハンマに対しても変更する場合が生じるため、印字ハンマを駆動させるコイルの発熱量が必要以上に増加しハンマの熱変形等により結果として印刷品質の低下につながる。
However, according to the conventional technology, the total number of printing dots in one stroke or the number of printing dots for each block is small and the printing dots are locally concentrated in the printing range, or the printing dots are on a specific adjacent printing hammer. Even in the case of concentrated printing, the print quality tends to deteriorate due to the influence of magnetic interference caused by the simultaneous driving of the print hammer between adjacent print hammers.
As conventional means for avoiding this, use is made of divided printing or means for changing the drive current value of the printing hammer. However, when the divided printing is executed, the printing execution speed is reduced with a small number of printing dots.
FIG. 7 shows a schematic view of hammer springs in an N = 12 row arrangement.
The printing hammers arranged in N columns (for example, N = 12) in the vertical direction with respect to the printing row have a difference in the operating speed of the printing hammer after release in each of the N columns due to the difference in the wraparound of the magnetic flux from the adjacent core. As a result, the printing force that affects the printing density and the reaction time (repeatability) required for the series of operations of releasing, printing, and attracting the printing hammer are non-uniform for each of the N rows, which is affected by magnetic interference. There is also a difference.
FIG. 8 shows the printing power of the printing hammer in each row of N = 12 rows. Even when the current value is changed in the direction in which the current product of the printing hammer drive current increases for each block, the printing power of the printing hammers in each of the N columns in each block remains uneven. Therefore, a uniform change in current value causes a difference in print quality, particularly print density, resulting in printing defects such as print density. Furthermore, if the current value is changed evenly, the print hammer that does not need to be changed may be changed. Therefore, the amount of heat generated by the coil that drives the print hammer increases more than necessary, resulting in thermal deformation of the hammer. As a result, the print quality is degraded.

板バネと印字ピンで構成されており、印刷行と垂直方向に所定ピッチでN列に並べられた印字ハンマを1単位とし前記印字ハンマを印刷行方向に複数個並べて配置したハンマモジュールと、前記印字ハンマを非印刷位置に保持する磁石手段と、前記印字ハンマを駆動させる釈放用電磁コイルを有するハンマ機構部と、該ハンマ機構部を印刷行方向に往復運動させるシャトル機構部とを備え、シャトルの右又は左方向へのストロークの過程で印字ハンマを駆動させ、1ストロークでNドットラインを印刷するドットラインプリンタにおいて、印刷前にシャトル機構部1ストローク内の全印刷ドット数を各印字ハンマ毎にカウントする印刷ドット数カウント手段を設け、1ストローク内の印字ハンマ毎の印刷ドット数に規定値を設け、各印字ハンマの印刷ドットのカウント数が規定値を超えた印字ハンマについて、駆動電流の電流積が大きくなる方向に電流値を変更する。また、1ストローク内の印字ハンマの印刷ドット数に複数の規定値と各規定値に対応する駆動電流のパルス幅を設けてやり、各印字ハンマの印刷ドットのカウント数が各規定値を超える毎に、対応した駆動電流のパルス幅に可変する、更には、1ストローク内の印字ハンマ毎の印刷ドット数に規定値を設け、該規定値をNドットライン毎に個別に設ける。   A hammer module comprising a leaf spring and a printing pin, wherein a printing hammer arranged in N columns at a predetermined pitch in a vertical direction with respect to a printing line is a unit, and a plurality of the printing hammers are arranged in the printing line direction; A shuttle, comprising: magnet means for holding the printing hammer in a non-printing position; a hammer mechanism having a release electromagnetic coil for driving the printing hammer; and a shuttle mechanism for reciprocating the hammer mechanism in the printing line direction. In a dot line printer that drives a printing hammer in the process of a stroke in the right or left direction and prints N dot lines in one stroke, the total number of dots printed in one stroke of the shuttle mechanism unit is printed for each printing hammer before printing. Printing dot count counting means is provided, and a specified value is set for the number of printing dots for each printing hammer within one stroke. For printing hammer to count number of printing dots exceeds a predetermined value, changes the current value in the direction in which the current product of the drive current increases. In addition, a plurality of prescribed values and a drive current pulse width corresponding to each prescribed value are provided for the number of print dots of a printing hammer within one stroke, and the count of printed dots of each print hammer exceeds each prescribed value. In addition, the pulse width of the corresponding drive current is varied, and a specified value is provided for the number of print dots for each print hammer within one stroke, and the specified value is provided for each N dot line.

本発明によれば、印刷ドットが印刷範囲の局部的に集中する印刷、或いは印刷ドットが特定の隣接する印字ハンマに集中する印刷の場合に、印刷前にシャトル機構部1ストローク内の各印字ハンマ毎の印刷ドット数に規定値を設けてやり、各印字ハンマの印刷ドットのカウント数が規定値を超えた印字ハンマについて駆動電流の電流積が大きくなる方向に電流値を変更する。   According to the present invention, in the case of printing in which the printing dots are concentrated locally in the printing range, or printing in which the printing dots are concentrated on a specific adjacent printing hammer, each printing hammer within one stroke of the shuttle mechanism unit before printing is performed. A predetermined value is set for each print dot number, and the current value is changed in a direction in which the current product of the drive current increases for the print hammer in which the print dot count number of each print hammer exceeds the predetermined value.

また、1ストローク内の印字ハンマの印刷ドット数に複数の規定値と各規定値に対応する駆動電流のパルス幅を設けてやり、各印字ハンマの印刷ドットのカウント数が各規定値を超える毎に、対応した駆動電流のパルス幅に可変する、更には、1ストローク内の印字ハンマ毎の印刷ドット数に規定値を設け、該規定値をNドットライン毎に個別に設けることにより、より詳細な印刷データの管理、制御が可能となるため印刷実行速度の低下を防止し、印刷濃度のバラツキ、コイルの発熱量を最小限に抑制し、安定した印刷品質を提供できる。   In addition, a plurality of prescribed values and a drive current pulse width corresponding to each prescribed value are provided for the number of print dots of a printing hammer within one stroke, and the count of printed dots of each print hammer exceeds each prescribed value. Further, by changing the pulse width of the corresponding drive current, and further providing a specified value for the number of printing dots for each printing hammer in one stroke, and providing the specified value individually for each N dot line, more details can be obtained. Therefore, it is possible to manage and control the print data properly, thereby preventing a decrease in the print execution speed, minimizing variations in print density and heat generation of the coil, and providing stable print quality.

印刷ドットが印刷範囲の局部的に集中する印刷、或いは印刷ドットが特定の隣接印字ハンマに集中する印刷による印刷品質の低下の抑制を、部品点数を増やすことなく制御手段を変更することで実現した。   By controlling printing without increasing the number of parts, we have achieved a reduction in print quality due to printing where printing dots are concentrated locally in the printing range, or printing where printing dots are concentrated on specific adjacent printing hammers. .

図示しない上記装置から転送された印刷データは、印刷データバッファ2に格納され、印刷データカウント手段3により全印刷ドット数がカウントされる。また同時に印刷ドット数カウント手段4により各印字ハンマ毎の印刷ドット数がカウントされる。上記2種類のデータがマイコン6に読み込まれ、図2、図3、図4のステップ004に示すように全印刷ドット数が規定値Aより大きい場合は、ステップ005により打ち分け制御手段5を介してハンマ駆動手段7に指示を送り打ち分け印刷を実行する。
図2に示すようにステップ004により全印刷ドット数が規定値Aより小さい場合は、ステップ007に進み、各印字ハンマの印刷ドット数のうち、規定値Bより大きい印字ハンマはステップ008により駆動電流値Cで駆動、規定値Bより小さい印字ハンマはステップ009により駆動電流値Dで駆動する指示をハンマ駆動手段7に送り、それぞれ指示された駆動電流値にて印刷を実行する。
また、図3に示すようにように更に規定値Bの下に、ステップ010により規定値Eを設け、規定値Eより大きい印字ハンマはステップ011により駆動電流値Gで駆動、規定値Eより小さい印字ハンマはステップ012により駆動電流値Fで駆動する指示をハンマ駆動手段7に送り、それぞれ指示された駆動電流値にて印刷を実行するというように規定値を複数設け、各規定値毎に駆動電流値を可変させる。
更に、図4に示すようにステップ004により全印刷ドット数が規定値Aより小さい場合はステップ013〜024により、各印字ハンマの例えばN=1〜12列のそれぞれに規定値B〜Mを設け、各規定値B〜Mより大きい場合はステップ025により駆動電流値Nで駆動、規定値B〜Mより小さい場合はステップ026により駆動電流Pで駆動させる。規定値B〜Mについては例えば印字力のバラツキを考慮し、印字力が小さい場合は規定値を小さく、印字力が大きい場合は規定値を大きく設定し、印刷品質のバラツキを抑制できるよう設定すれば良い。
The print data transferred from the apparatus (not shown) is stored in the print data buffer 2 and the total number of print dots is counted by the print data counting means 3. At the same time, the printing dot number counting means 4 counts the number of printing dots for each printing hammer. When the two types of data are read into the microcomputer 6 and the total number of printed dots is larger than the specified value A as shown in step 004 of FIGS. Then, an instruction is sent to the hammer drive means 7 to execute printing.
As shown in FIG. 2, when the total number of print dots is smaller than the specified value A in step 004, the process proceeds to step 007, and among the print dots of each print hammer, the print hammer larger than the specified value B is driven by step 008. The printing hammer driven at the value C and smaller than the specified value B sends an instruction to drive at the driving current value D to the hammer driving means 7 at step 009 and executes printing at the instructed driving current value.
Further, as shown in FIG. 3, a specified value E is provided at step 010 below the specified value B as shown in FIG. 3, and a printing hammer larger than the specified value E is driven at the drive current value G at step 011 and is smaller than the specified value E. In step 012, the print hammer sends an instruction to drive with the drive current value F to the hammer drive means 7, and a plurality of specified values are provided such that printing is performed with the specified drive current value, and the print hammer is driven for each specified value. Variable current value.
Further, as shown in FIG. 4, when the total number of printed dots is smaller than the prescribed value A in step 004, prescribed values B to M are provided for each of the printing hammers, for example, N = 1 to 12 rows, in steps 013 to 024. If it is larger than the prescribed values B to M, it is driven with a drive current value N in step 025, and if it is smaller than the prescribed values B to M, it is driven with a drive current P in step 026. For the specified values B to M, for example, in consideration of variations in printing force, the specified value is set to be small when the printing force is small, and the specified value is set to be large when the printing force is large, so that the variation in printing quality can be suppressed. It ’s fine.
