一般に感熱プリンターの印字ヘッドは同一発熱体に印字

却する等の処置がとられていた。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a thermal printing method using a thermal printer [Technical Background of the Invention] Generally, the print head of a thermal printer prints pulses continuously at high speed on the same heating element. When this voltage is applied, there are problems such as damage to the print head due to the heat generated by the heating element. For this reason, thermal printers that perform high-speed printing use print heads with good heat dissipation, and take measures such as cooling the head quickly after printing.
すなわち印字速度は、感熱印字ヘッドの性能に依存して
おり、これ以上の高速印字が要求される場合は複数の感
熱プリンターを用いて疑似的に印字を速める方法が用い
られていた。That is, the printing speed depends on the performance of the thermal print head, and when higher speed printing is required, a method of artificially speeding up printing using multiple thermal printers has been used.
第１図はこの複数台の感熱プリンタを用いた感熱印字方
式を示すもので簡単のために２台の感熱プリンタを用い
た場合が示されている。FIG. 1 shows a thermal printing method using a plurality of thermal printers, and for the sake of simplicity, a case where two thermal printers are used is shown.

行う。First, input signal 1 is sent to printer a via changeover switch 2.
and stored in the data buffer 3a. The data buffer 3a converts the input signal 1 from a character code into a character pattern, adds it to the line buffer 4a line by line, and drives the print head 6a via the head drive circuit 5a to perform predetermined printing on thermal recording paper. If the input signal for the next document is sent continuously before printer a finishes printing one page of document, the changeover switch 2 is switched to the printer b side, and the same operation causes the input signal 1 to be sent.
is applied to the line buffer 4b via the changeover switch 2 and the data buffer 3b, and the print head 6b is driven by the head drive circuit 5b to print on the thermal recording paper.
このように、ある印字速度の感熱プリンタを複数台用い
て、この印字速度とこの台数との槓に相当する速度の高
速人力信号に対昶Ｊしていた。In this way, a plurality of thermal printers with a certain printing speed are used to respond to a high-speed human input signal with a speed corresponding to the printing speed and the number of thermal printers.
〔背景技術の問題点コ
しかしながら上記従来の方式は矢数枚の原稿を連続して
印字するような場合には効果があるが、印字データが断
続的に入力される場合等には使用効率を低下させるだけ
となって全く効果が期待できず、更に複数台のプリンタ
ーを必要とするため機器の設置スペースもかなり広いも
のが要求されるという欠点があった。[Problems with the background art] However, although the above-mentioned conventional method is effective when printing several sheets of originals continuously, it is difficult to use efficiently when printing data is input intermittently. There was a drawback that no effect could be expected as it only reduced the quality of the printer, and that it required multiple printers, which required a fairly large installation space for the equipment.
本発明は上述した欠点を除去するためになされたもので
印字速度の高速化をはかることができしかも機器の表置
スペースも小さくすることができる感熱印字方式を提供
することを目的とする。The present invention has been made to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a thermal printing method that can increase the printing speed and also reduce the space required for displaying the device.
そこで本発明においては、印字ヘッドと感熱記録紙の送
シ方向に対して複数個並設し、該複数個の印字ヘンドを
同時にまたは印字タイミングをずらして駆動させること
により高速印字を可能にしている。Therefore, in the present invention, high-speed printing is made possible by arranging a plurality of print heads and thermal recording paper in parallel in the feed direction, and driving the plurality of print heads simultaneously or with staggered print timings. .
またこの場合印字ヘッドを制御する周辺回路のみを印字
ヘッドに対応する数だけ設ければ構成できるので機器の
外形を小型化することができる。In addition, in this case, the configuration can be achieved by providing only the number of peripheral circuits that control the print heads, corresponding to the number of print heads, so that the external size of the device can be reduced.
以下本発明の実施例を添付図面にもとづき詳細に説明す

される。The printer 14 according to the present invention has a first print path consisting of a data buffer 7, a line buffer 8, a head drive circuit 9, and a print head 10; The two print heads 10 and 13 are spaced apart by a line interval in a direction perpendicular to the scanning direction of the thermal recording paper. First, input signal 1 indicating print information is applied to data buffer 7 and stored. In this data buffer 7, the human input signal 1 is converted from a character code to a character pattern, and the character pattern in the first line is sent line by line to the line buffer 8 along the first printing path and stored as pattern data.
また第２行の文字パターンは第２の印字系路をたどり、

ことができる。In this way, one input signal 1 is processed by the data buffer 7 in the first . The print heads io, i3=<< are distributed to the second printing system path, and two lines of printing are performed simultaneously. When the printing of these two lines is completed, the application of printing pulses to the print heads 10 and 13 is stopped, and a certain period of idling is performed. During this period, the thermal recording paper is fed by two lines, and when the certain period of idling ends, the data buffer 7 is transmits the print information of the third line to the print head 10 via the first print system path, and also sends the print information of the fourth line to the print head L3 via the second print system path to print these two lines. Do it at the same time. Thereafter, in the same manner, two lines are printed at a time while taking a predetermined idle time. According to this method, since two lines are printed simultaneously, the printing speed can be doubled compared to the case of a single head.
なお上記実施例では２個の印字ヘッドを並設した場合を
示したが３個以上の印字ヘッドを並設しても同僚に構成
できるのは勿論である。Although the above embodiment shows a case in which two print heads are installed side by side, it is of course possible to arrange three or more print heads in parallel.
以上の説明は文章等の印字をするプリンターの場合の例
であり各行の間にスペースかりる場合の説明であるが、
図形等他の印字の場合においても印字ヘッドの実装でき
る間隔分毎をフロックに分けて異ブロックを同時に印字
することにより同様に印字の高速化が図れる。The above explanation is an example of a printer that prints text etc., and it is an explanation when there is a space between each line.
In the case of other types of printing such as graphics, printing speed can be increased in the same way by dividing the blocks into flocks at intervals where the print head can be mounted and printing different blocks at the same time.
〔発明の効果」
以上説明したように本発明によｆＬは該数個のヘッドを
感熱記・録紙送り方向に並設して印字するのでろるから
既存技術でのヘッドの性能で印字速度を速くすることが
できる。これは蓮数針のプリンターを並べて印字させる
場合に比べて、断続的人力でも印字速度の低下はなくし
かもヘッド周辺の回路のみ複数個用意するだけであるか
らプリンター自身の外形寸法もあまり大きくならないの
で設置スペースも少なくなる。[Effects of the Invention] As explained above, according to the present invention, fL prints by arranging several heads in parallel in the thermal recording/recording paper feeding direction, so the printing speed is lower than that of the head performance of the existing technology. can be made faster. This is because, compared to the case where printers with lotus needles are arranged side by side to print, there is no drop in printing speed even with intermittent manual labor, and since only multiple circuits around the head are required, the external dimensions of the printer itself do not increase too much. Installation space is also reduced.
なお、印字ヘッドは印字パルス印加後冷却のため一定期
間アイドルが必要なためこの期間に他の印字ヘッドに印
字パルスを印加できるようにヘッドを前面すれば延源谷
量は［：１３字ヘッド１台分ですむ。Note that the print head needs to be idle for a certain period of time to cool down after applying the print pulse, so if the print head is placed in front so that the print pulse can be applied to other print heads during this period, the noboru valley amount will be [:13 character head 1 It only takes one car.
さらにラインプリンターでは一つの印字ヘッドが印字中
残りのヘッドを行間フィードさせておくと電源が１台分
で漕むとともに行バツフアも１個で営み小型化される。Furthermore, in a line printer, if one print head feeds the remaining heads between lines while printing, the power supply is needed for one printer, and the line buffer is also operated by one unit, resulting in miniaturization.
