本発明は、熱転写プリンタに関し、特にインクリボン走
行不良を検出する機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a thermal transfer printer, and particularly to a mechanism for detecting ink ribbon running failure.
この種の熱転写プリンタは、用紙に対向して用紙の幅方
向に走行する印字ヘッドと、用紙と印字ヘッドとの間に
配置され、印字ヘッドの印字動作に同期して走行するイ
ンクリボンとを有している。This type of thermal transfer printer has a print head that faces the paper and runs in the width direction of the paper, and an ink ribbon that is placed between the paper and the print head and runs in synchronization with the printing operation of the print head. are doing.
上述した従来の熱転写プリンタは、インクリボンの走行
状態を検出する機構を持っていなかったので、何らかの
不具合でインクリボンの巻取り負荷が増し、インクリボ
ンの巻取りが不能になっても、プリンタの印字動作が停
止しないため、印字データが用紙上に転写されないとい
う欠点があった。The conventional thermal transfer printers mentioned above did not have a mechanism to detect the running state of the ink ribbon, so even if the ink ribbon winding load increases due to some malfunction and the ink ribbon cannot be wound, the printer will not be able to operate. Since the printing operation does not stop, there is a drawback that the print data is not transferred onto the paper.
本発明の熱転写プリンタは、インクリボンベース上に、
一定間隔でマークを印刷したインクリボンと、そのマー
クを検出するセンサーとセンサーの出力によりインクリ
ボンが走行しているか停止しているかを判断する検出す
る検出回路とを有している。The thermal transfer printer of the present invention includes, on an ink ribbon base,
It has an ink ribbon on which marks are printed at regular intervals, a sensor that detects the marks, and a detection circuit that determines whether the ink ribbon is running or stopped based on the output of the sensor.
次に、本発明の一実施例について、図面を参照して説明
する。Next, one embodiment of the present invention will be described with reference to the drawings.

を通過し、巻取りコア５に巻取られる。FIG. 1 is a diagram showing the ink ribbon traveling mechanism and the position of the sensor.
It is pulled out by running on it. pulled out,
After printing, the ink ribbon 1 passes through the detection position of the sensor 4 and is wound around the winding core 5.
第２図は、本発明の熱転写プリンタに使用するインクリ
ボンを示す図であり、インクリボンベース６の上にイン
ク７を塗布し、一定間隔で、マーク８を印刷しである。FIG. 2 is a diagram showing an ink ribbon used in the thermal transfer printer of the present invention, in which ink 7 is applied onto an ink ribbon base 6 and marks 8 are printed at regular intervals.
第３図は、インクリボンの走行状態の検出回路の一実施
例であり、本実施例では、インクリボン１上のマーク８

る。又、第４図はその検出回路内の信号のタイムチャー
トである。FIG. 3 shows an embodiment of a detection circuit for detecting the running state of the ink ribbon.
A reflective sensor 4 is used as a detection sensor. Further, FIG. 4 is a time chart of signals within the detection circuit.
インクリボン１の走行動作が正常であれば、インクリボ
ン１上のマーク８がセンサー４の前面を走行し、センナ
出力信号９は第４１３！ｆＩのインクリポ。If the ink ribbon 1 is running normally, the mark 8 on the ink ribbon 1 will run in front of the sensor 4, and the sensor output signal 9 will be the 413th! fI's ink report.

信号すのレベルが閾値電圧を越え、信号Ｃは旧ｇｈレベ
ルになる。The waveform is within the range of normal running A. At this time, signal a
The signal C does not exceed a certain threshold voltage, and the signal C is Lo.
It is maintained at the educational level. On the other hand, the running operation of the ink ribbon l has stopped due to some abnormality, or the ink ribbon 1 has been pulled out by the print head 2, but the winding core 5 is not winding it up properly, and the mark 8 on the ink ribbon l is not on the sensor 4. When the ink ribbon stops in front of the ink ribbon, the sensor output signal 9 has a waveform within the ink ribbon stop area C in FIG. At this time,
The level of the signal C exceeds the threshold voltage, and the signal C becomes the old gh level.
又、マーク８がセンサー４の前面外で停止した場合、セ
ンサ出力信号９は第４図のインクリボン停止Ｂ領域内の
波形となる。このとき、信号ａのレベルが閾値電圧を越
え、信号Ｃは旧ｇｈレベルになる。Further, when the mark 8 stops outside the front surface of the sensor 4, the sensor output signal 9 has a waveform within the ink ribbon stop area B in FIG. At this time, the level of signal a exceeds the threshold voltage, and signal C becomes the old gh level.
以上説明したように、本発明は、何らかの異常で、イン
クリボンの走行不良、又はインクリボンの巻取り不良が
発生した場合、その異常を即時検出し、印字動作を停止
