この発明は感熱記録装置、特に紙の無駄を極力少なくす
るようにした感熱記録装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal recording device, and particularly to a thermal recording device designed to minimize paper waste.

になるという不具合があった。As shown in FIG. 1, a conventional thermal recording apparatus passes a recording paper 2 fed from a thermal recording paper roll 1 through a roller 3, a recording head 4, a feed roller 5, and a cutter 7.
The paper is fed by driving the feed roller 5 by the rotation of the mokuro. Therefore, after the recording paper 2 is cut by the cutter 7, the motor 6 is immediately stopped, and the next recording starts from this stop position.
There was a problem in that the recording paper portion up to the contact point of the back row 23 was completely wasted.

To provide a thermal device which rewinds the cut edge of paper to the vicinity of the contact point between a back roller and a recording head, and maintains the stretched state of the paper during this rewinding.
以下本発明を添附図面の実施例について詳細に説明する
。Hereinafter, the present invention will be described in detail with reference to embodiments shown in the accompanying drawings.

するためのものである。FIG. 2 shows that the thermal recording device of the present invention cuts the recording paper 2 into the cutter 7.
This shows the state immediately after cutting. A device is provided between the thermal paper roll 1 and the back roller 3 to constantly spread the recording paper 2. In FIG. 2, the contact piece 11 is pivoted to a fixed point, and the recording paper 2 is constantly moved through the contact piece 11 by the arrow A.
An example is shown in which a spring 12 is provided to push the device toward. The back row 23 is connected to the motor 9 so as to be directly driven by the motor 9.
The forward and reverse rotations of the motor 9 result in forward and reverse rotation. The pinch roller 8 is driven by the back roller 3 and inserts the recording paper 2 between it and the back row 23 to move the recording paper 2 forward or backward. The guide 10 is provided along the recording paper path between the back roller 3 and the pinch roller 8 and the cutter, and is intended to prevent the recording paper 2 from twisting while moving back and forth.
カッター７による記録紙２の切断が行われると、カッタ
ー７の切断動作を電気的に検出して１パルスを発生させ
、これをモータ制御装置１１に加える。When the cutter 7 cuts the recording paper 2, the cutting operation of the cutter 7 is electrically detected to generate one pulse, which is applied to the motor control device 11.
カッター７の切断動作の電気的検出はたとえばカッター
の回動軸に設けたカム（図示せず）の回動によって所定
位置に設けたリミットスイッチ（図示せず）を作動させ
ることによって行えばよい。The cutting operation of the cutter 7 may be electrically detected by, for example, rotating a cam (not shown) provided on the rotating shaft of the cutter to activate a limit switch (not shown) provided at a predetermined position.
カッター７の切断動作の横目は電気的、光学的、磁気的

数のパルスをモータ９に供給する。これによりモータ９
は逆転し第３図の如き位置で停止する。The cutting operation of the cutter 7 may be performed using any electrical, optical, or magnetic means, as long as it can detect the movement of the cutter 7. Motor control device 11
As mentioned above, when the cutter 7 receives a pulse indicating cutting, the number of pulses corresponds to the total rotation angle of the back roller 3 necessary to rewind the recording paper 2 from the state shown in FIG. 2 to the state shown in FIG. pulses are supplied to the motor 9. This causes motor 9
is reversed and stopped at the position shown in Figure 3.
上記記録紙２の巻戻しの間記録紙ロール１とバックロー
ラ３間の記録紙２はロール１が回転されないため、巻戻
し分だけ余剰が生じることになるが前述の如くバネ１２
の押圧力によって矢印入方向に押圧されるので、記録紙
２は常に展張状態を保持する。従ってその後バックロー
ラ３が正転されるとき記録紙がよじれたシすることがな
くなる。During the rewinding of the recording paper 2, since the roll 1 is not rotated, the recording paper 2 between the recording paper roll 1 and the back roller 3 will have a surplus corresponding to the amount of unwinding.
Since the recording paper 2 is pressed in the direction indicated by the arrow by the pressing force, the recording paper 2 always maintains a stretched state. Therefore, when the back roller 3 is subsequently rotated forward, the recording paper will not be twisted.

た状態に保持することができる。尚樹脂片に限らず適当
な弾性片であってもよい。FIG. 4 shows another example in which the recording paper 2 is constantly stretched between the recording paper roll 1 and the back roller 3.
One end of the resin piece 13 is fixedly supported on a peripheral fixed body, and at this time, the resin piece 13
deflect the mounting direction inward. In this way, the excess amount of the recording paper 20 when the back roller 3 is reversed can be absorbed as shown in the figure, and the recording paper 2 can be kept in a stretched state at all times. Note that the material is not limited to a resin piece, but may be an appropriate elastic piece.
本発明は上記のような簡単な構成で感熱記録紙の無駄を
