本発明は可変速度走査を行い、かつ栽断された
記録紙を用いる記録装置における、連続記録時の
記録紙の給紙方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording paper feeding method during continuous recording in a recording apparatus that performs variable speed scanning and uses chopped recording paper.
裁断された記録紙で記録を行う記録装置では、
連続記録を行う場合、記録紙同士の間隔をできる
だけ短かく設定して記録部に給送することが効率
的な記録を行ううえで必要な条件となる。 In a recording device that records using cut recording paper,
When performing continuous recording, a necessary condition for efficient recording is to set the interval between recording sheets as short as possible before feeding them to the recording section.
ところで近時においては帯域圧縮技術等の活用
により画情報に応じて記録紙の記録速度を変動さ
せる記録装置が多くなつている。このような記録
装置で先に記録を行う記録紙の後端に次に記録を
行う記録紙の先端を接近させた状態で給送したと
する。この場合、先の記録の記録速度が記録部に
おいて低下すると、これにも係らず一定速度で給
送される後の記録紙が先の記録紙に重なり合い、
先の記録紙の後端が記録されないという不都合が
生じてしまう。もちろん次の記録紙もこの場合正
常な記録が不可能となる。 Incidentally, in recent years, there have been an increasing number of recording apparatuses that use band compression techniques and the like to vary the recording speed of recording paper according to image information. Suppose that such a recording apparatus feeds a recording paper to be printed next with its leading edge approaching the trailing edge of the recording paper to be printed first. In this case, when the recording speed of the previous recording decreases in the recording section, the subsequent recording paper that is fed at a constant speed despite this decreases, overlapping the previous recording paper.
This results in the inconvenience that the trailing edge of the previous recording paper is not recorded. Of course, normal recording on the next recording paper is also impossible in this case.
このような理由から裁断された記録紙を用いる
この種の記録装置では、連続記録を行う場合に先
の記録紙の記録が完了してから次の記録紙の給送
を開始していた。しかしながらこのような給紙方
法を採用すると、記録装置の記録速度が向上して
も給紙のための無駄時間が発生し、十分効率的な
記録を行うことができないという欠点があつた。
このような欠点を解決するために先の記録紙が給
紙トレイから送り出された直後に次の記録紙を記
録の最低速度で送り出すことが提案されている。
この方法では後に送り出された記録紙が先に送り
出された記録紙と重なり合うという問題が解決さ
れる。しかしながらこの方法では先の記録紙が例
えば白ブロツク飛越し符号化（WBS）により高
速で走査される場合があると、後の記録紙との間
隔が開き、前述した無駄時間が同様に発生してし
まう。 For these reasons, in this type of recording apparatus that uses cut recording paper, when performing continuous recording, feeding of the next recording paper is started after the recording of the previous recording paper is completed. However, when such a paper feeding method is adopted, even if the printing speed of the printing apparatus is improved, wasted time is generated for paper feeding, and there is a drawback that sufficiently efficient printing cannot be performed.
In order to solve this problem, it has been proposed to feed the next recording sheet at the lowest recording speed immediately after the previous recording sheet is fed out from the paper feed tray.
This method solves the problem that the recording paper sent out later overlaps the recording paper sent out earlier. However, with this method, if the previous recording paper is scanned at high speed due to white block skipping coding (WBS), for example, the gap between the following recording paper increases and the wasted time described above also occurs. Put it away.
本発明はこのような事情に鑑みてなされたもの
で、可変速度走査を行い、かつ裁断された記録紙
を用いる記録装置において、連続記録時に記録紙
の間隔を最小に保つて給送させることのできる記
録紙の給紙方法を提供することを目的とする。 The present invention has been made in view of the above circumstances, and it is a recording device that performs variable speed scanning and uses cut recording paper. The purpose of this paper is to provide a recording paper feeding method that is possible.
本発明では記録部における記録紙の副走査速度
と略同一速度で次に記録部へ送られる記録紙を給
送することとして、前記した目的を達成する。 In the present invention, the above-mentioned object is achieved by feeding the next recording paper to the recording section at substantially the same speed as the sub-scanning speed of the recording paper in the recording section.
以上実施例につき本発明を詳細に説明する。 The present invention will be described in detail with reference to the embodiments above.

記録装置で連続記録を行う場合の記録紙の給紙方
法を次に説明する。 FIG. 1 shows a thermal recording apparatus employing a variable speed scanning method. In this apparatus, an ink donor sheet 1 coated with heat-fusible or heat-sublimable solid ink is selectively heated by a thermal head 2, and the melted or sublimated ink is transferred onto recording paper 3 to record image information. Next, a method of feeding recording paper when continuous recording is performed with this thermal recording apparatus will be explained.

When the feed roller 4 is driven, the uppermost stacked recording paper 3 that is in contact with the feed roller 4 in the paper feed tray 5 is sent out in the direction of an arrow 6.

When the paper sensor 7 detects the leading edge of the recording paper 5 at time t2 (FIG. 2a), a pair of register rollers 8 are driven from time t3 slightly later (FIG. 2d), and the recording paper 3 is captured by this register roller 8. When the recording paper 3 is captured by the register roller 8, the leading edge of the recording paper 3 is detected by the registration sensor 9 located adjacent to the front of the register roller 8 at time t4 , which is a little later (see FIG. 2). b).
At this time t4 , the drive of the feed roller 4 is stopped (FIG. 2c), and the recording paper 3 is thereafter fed forward at a speed that matches the circumferential speed of the register roller 8.

The back roller 11 is pressed against the thermal head 2 via the ink donor sheet 1. Accordingly, when the back roller 11 is energized, the ink donor sheet 1 is fed out from the supply roller 12, passed through the recording section 13 that comes into contact with the thermal head 2, and then wound onto the take-up roller 14.

It is sent to the recording section 13. any time t 6 after this
At this point, the drive of the register roller 8 is stopped (FIG. 2d). On the other hand, the back crawler 11 performs so-called white line skipping, in which the circumferential speed is increased when there is no image information to be recorded. When the recorded recording paper passes between the back roller 11 and the peeling roller 12, it is peeled off from the ink donor sheet 1 and discharged in the direction of arrow 15.

The peripheral speed of the feed roller 4 at this time is
The circumferential speed of the back roller 11 is maintained at the same speed as the back roller 11 by control of a control circuit (not shown) that controls the circumferential speed of the back roller 11 . Furthermore, the circumferential speed of the register roller 8, which is energized at time t9 after time t8 , is maintained at the same speed as that of the back roller 11 under the control of the control circuit described above (FIG. 2d).

The register roller 8 feeds the second sheet of recording paper at a prescribed constant speed after time t10 , and causes the recording section 13 to start recording. The feeding method for the third and subsequent sheets of recording paper is also similar.
