〔産業上の利用分野〕
本発明はプリンタに関し、特にドツトシリアルプリンタ
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to printers, and more particularly to dot serial printers.
従来、この種のプリンタの印字ヘッドは第７図に示すよ
うに規定行幅Ｑ内に規定数のＮ個の発熱体Ｄ１〜Ｄ、ｌ
を印字方向に対し直角方向に配列させており、印字指
令に基づいて特定の発熱体Ｄ工〜Ｄｎを駆動して１行分
の印字を行っていた。Conventionally, the print head of this type of printer has a prescribed number of N heating elements D1 to D, l within a prescribed line width Q, as shown in FIG.
are arranged in a direction perpendicular to the printing direction, and specific heating elements D to Dn are driven to print one line based on a printing command.
上述した従来のプリンタでは次に述べる２つの理由によ
って行間に隙間ができ、特に図形、絵などのグラフィッ
クを印字させたときにはこの隙間が際立って目立ち、印
字品質を著しく低下させるという欠点がある。The above-mentioned conventional printer has the drawback that gaps are created between lines due to the following two reasons, and these gaps are particularly noticeable when printing graphics such as figures and pictures, resulting in a significant deterioration of print quality.
第１の理由は改行時におけるメカニカルな誤差によるも
ので、改行幅に余裕がないため、この誤差が現れたとき
行間の隙間として印字結果に現れる。The first reason is due to a mechanical error at the time of line feed, and since there is no margin for line feed width, when this error appears, it appears in the print result as a gap between lines.
第２の理由はサーマルプリンタにおける特有のもので、
各発熱体はそれぞれ一定の熱量によって発熱し印字する
わけであるが、周囲の発熱体の温度の影響により配列さ
れた発熱体の中心部の方が端の発熱体に比べ温度が高く
なり、その分行間の印字濃度が低くなり隙間として印字
結果に現れる。The second reason is unique to thermal printers.
Each heating element generates a certain amount of heat and prints, but due to the influence of the temperature of the surrounding heating elements, the temperature in the center of the array of heating elements is higher than that of the heating elements at the edges. The print density between lines becomes low and appears as a gap in the print result.
隙間をなくす手段として、改行幅を減らすという方法も
あるが、この方法では１回での改行誤差は微小なもので
あるが、１ページに打ち出して全体的に見ると、各行の
累計誤差が現れてしまい、グラフィックなどを印字した
とき、タテ・ヨコ比が異なり、全体としてゆがんでしま
うという２つの問題点がある。One way to eliminate gaps is to reduce the line break width, but with this method, the line break error at one time is minute, but when you print it out on one page and look at it as a whole, the cumulative error of each line becomes apparent. There are two problems: when printing graphics etc., the vertical and horizontal ratios will be different and the overall image will be distorted.
本発明の目的は行間での印字を可能ならしめ。An object of the present invention is to enable printing between lines.
グラフィックなどの印字品質を向上するプリンタを提供
することにある。The purpose of the present invention is to provide a printer that improves the printing quality of graphics and the like.
本発明は規定行幅内に配列された規定数の発熱体に連続

An extended heating element D9.1 for graphic printing is provided at a position continuous with 0 and beyond the line width Q. FIG. 2 shows a print head drive circuit, and this embodiment is for a print head in which the prescribed number of heating elements is 24, and in addition to these, one extended heating element D2s is provided. As shown in the figure, each heating element D~D241D25 has a NOT circuit N□~I'
One input terminal of the NOT circuit N knee 1'lzs is connected to a register for editing data, and the other input terminal is inputted with an STR signal.

かどうかを決定する。Also, one input terminal of the NOT circuit circuit NN is connected to the NOT circuit in the previous stage.
It is common to the input signal of circuit N24, and the other input terminal is connected to AND circuit N2. is connected. In the embodiment, as shown in FIG. 3, when a printing request is input and printing data is received, the data is analyzed and the request is to print a graphic with a noticeable gap between lines, or what is the gap? It is determined whether the request is to print an unrelated character string, and based on the result, the extended dot D2. Decide whether to use

2. At the same time as inputting signal A to each N07 circuit N1~
An STR signal is input to N□, and a specific heating element is operated by a specific register of register L according to the print data. Further, in this case, a signal to be inputted to the heating element D24 adjacent to the extended heating element D2s is input to the extended heating element 2S in common with the heating element D24, and printing is performed between the lines.

くい。In the previous embodiment, the extended heating element was provided at the final end of the row of heating elements D1-024, but in this embodiment, it is provided at the starting end of the row of heating elements D1-024. This embodiment is for a 24-dot thermal printer. First, the print data is analyzed to determine whether it is normal character data or a graphic, and if it is a graphic, the registers R1 and R2 are
is used to record 24 dots of data for one line in the register R, and when it moves to the next line, it is passed to the register R2, and from the register R2 the data is sent to the extended heating element D25 along with the STR1 signal. The register R starts recording the data for the next line again. In this way,
It will be printed twice for the extended heating element O2S,
Since the same data is printed, line spacing is less likely to be unnatural.
