を行なうシリアル記録装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a serial recording apparatus in which a recording head reciprocates and performs recording in both directions.
従来、シリアル型記録装置では、高速記録を行なうた

遅れがあるため、両方向記録を行なう際に印字ずれが発
生する。Conventionally, in a serial type recording apparatus, bidirectional recording is performed by reciprocating a recording head in order to perform high-speed recording. In this serial type recording apparatus, a drive signal necessary for moving the recording head (a driving pulse when the recording head is moved using a pulse motor) is given, and then the recording head actually reaches a target position. However, there is a time delay before printing, so that printing deviation occurs when performing bidirectional printing.

調整を行なっていた。Conventionally, in order to correct the displacement in both directions, adjustment has been performed for each device by shifting the pulse and time using a DIP switch or jumper wire while observing the actual printing result.

画像が得られ、高速、低騒音等の特色を有している。On the other hand, in recent years, a state change such as film boiling has occurred in ink due to thermal energy, and the ink is ejected from an ejection port toward a recording material by using bubbles generated by this, and characters, images, etc. Ink jet recording apparatuses of the so-called bubble jet type which perform recording of ink jet recording have been developed.
In this printing apparatus, the size of a heating resistor (heater) provided in each ejection port is much smaller than a piezoelectric element used in a conventional ink jet printing apparatus. For this reason, the ejection ports can be multi-layered at a high density, a high-quality recorded image can be obtained, and characteristics such as high speed and low noise can be obtained.

次に、上記にように構成された実施例の補正値検出動
作について、第4図に示すフローチヤート及び第5図に
示す記録ヘツドの移動模式図を参照して説明する。Next, the correction value detecting operation of the embodiment configured as described above will be described with reference to the flowchart shown in FIG. 4 and the schematic diagram of the movement of the recording head shown in FIG.
第4図に示すように、まず電源投入後にイニシヤル動
作(101)を行なった後、パルスモータ17を駆動して、
正方向へ、記録時加速と等しい速度でキヤリツジ15(記
録ヘツドH)を駆動する加速処理(102)を行なう(第
5図A〜B点)。As shown in FIG. 4, after the power is turned on, an initial operation (101) is performed, and then the pulse motor 17 is driven.
In the forward direction, an acceleration process (102) for driving the carriage 15 (recording head H) at the same speed as the recording acceleration is performed (points A and B in FIG. 5).
次に、RAM34内のカウンタAに1をセツトし(105)、
定速で1パルスずつ記録ヘツドHが移動(106)するた

行ない(110)、記録ヘツドHの移動を停止する(第5
図E点)。Next, 1 is set to the counter A in the RAM 34 (105),
Each time the recording head H moves one pulse at a constant speed (106), the level of the HP sensor 4 is detected (107), and if it is not ON, the counter A is incremented by one (10).
8). When the HP sensor 4 is turned on (point C in Fig. 5),
Then, the head H is moved by an arbitrary pulse N (109) (point D in FIG. 5). At this time, the counter A has B to C
The number of pulses between points is maintained. Thereafter, a deceleration process is performed (110), and the movement of the recording head H is stopped (fifth step).
(Figure E point).
次に、パルスモータ17を逆方向に駆動し、正方向の減
速と同じパルス数で負方向へ加速処理(111)を行なう
(第5図E〜F点)。そこで、上記カウンタAとは別の
RAM34内のカウンタMに1をセツト(112)し、負方向へ
1パルスずつ記録ヘツドHが移動(113)するたびにHP
センサ4のレベルを検出し(114)、OFF状態になってい
なければカウンタMをプラス1(115)する。Next, the pulse motor 17 is driven in the reverse direction to perform the acceleration process (111) in the negative direction with the same number of pulses as the deceleration in the positive direction (points E to F in FIG. 5). Therefore, another counter A
The counter M in the RAM 34 is set to 1 (112), and each time the recording head H moves by one pulse in the negative direction (113), the HP
The level of the sensor 4 is detected (114), and if it is not in the OFF state, the counter M is incremented by 1 (115).

ためHPセンサ4の切り替わる位置がずれるのでM>Nと
なっている。さらに、このずれは記録ヘツドHのインク
タンクの重量変化、つまり駆動負荷変動によって経時的
に変化する。When the HP sensor 4 is turned off (point G in FIG. 5), the counter M holds the number of pulses between points F and G. At this time, in an ideal drive system, the number of pulses applied to the pulse motor 17 should be equal and the moving distance should be equal, so that M = N. However, since the recording head H does not immediately follow the pulse given to the pulse motor due to the driving load, the switching position of the HP sensor 4 is shifted, so that M> N. Further, this shift changes with time due to a change in the weight of the ink tank of the recording head H, that is, a change in the driving load.

お、第5図においてガタ等に起因する固定値Bを考慮し
た図を破線で示す。以上で電源投入時点での負荷に対す
るズレ量Xが定まる。Actually, the drive system is not an ideal rigid body, and therefore has a play, and further has a system-specific shift factor such as a hysteresis of the HP sensor 4 and a circuit delay. These are combined to form a fixed value B, and the deviation amount X = MNB is stored in the RAM 34 (116). Next, after moving the recording head H by (A + NM) pulses in order to adjust the amount of movement of the recording head H in both the positive and negative directions (117), deceleration processing (118) is performed with the same number of pulses as the acceleration in the positive direction. (Point A in FIG. 5). Note that the broken line in FIG. 5 taking into account the fixed value B due to backlash or the like is shown. As described above, the displacement X with respect to the load at the time of turning on the power is determined.
次に、実際の記録動作について、第6図に示すフロー
チヤート及び第5図に示す記録ヘツドの移動模式図を参
照して説明する。Next, the actual recording operation will be described with reference to the flowchart shown in FIG. 6 and the schematic diagram of the movement of the recording head shown in FIG.

From there, recording (304) is performed according to the data (point J in FIG. 7), deceleration processing (305) is performed, and then the sheet is fed (306).

Point), and the data of the next line is recorded (310) (point R in FIG. 7). Then
After moving by (KX) pulse (311), deceleration processing (3
Perform step 12).
以上、この動作を繰返すことにより、1頁分の記録を

囲I−Jとほぼ同位置となる。FIG. 7 schematically shows the above operation. The horizontal axis represents the actual position of the recording head. After the acceleration process in the negative direction (point O), the printing range P is shifted to the right from the printing end point (point J) in the positive direction due to the delay of the driving system, but the print range P after correction by moving by X pulses. -R is substantially the same position as the print range IJ in the forward direction.

で、駆動負荷変動、特にインクタンク重量の経時変化に
よる変動に対しても、適切なズレ補正を行なうことがで
きる。As described above, in this embodiment, when the power is turned on, the recording head H is moved in both the positive and negative directions under the same conditions as during recording, and
The number of pulses up to the point where the signal crosses the sensor 4 is counted, and the bidirectional printing shift correction is performed based on the difference. Therefore, without adding cost and adjusting process,
It is possible to perform bidirectional printing misregistration correction with good accuracy.
Further, since the above-described correction operation is always performed when the power is turned on, it is possible to perform appropriate deviation correction even with respect to a change in driving load, particularly, a change due to a temporal change in the weight of the ink tank.
また、本実施例では上述のパルス数の差に加えてヘツ

で、より精度の良い両方向印字ズレ補正を行なうことが
できる。Further, in the present embodiment, in addition to the above-described difference in the number of pulses, misalignment correction is performed in consideration of the characteristic value of the head drive system, so that more accurate bidirectional printing misalignment correction can be performed.
なお本実施例では、正負記録領域を等しくおいて説明
したが、領域が異なり、最短距離印字を行なう場合も同
様に考えられる。In this embodiment, the positive and negative recording areas have been described as being equal. However, the case where the areas are different and the shortest distance printing is performed can be similarly considered.
又、第4図のようにオフライン状態からオンライン状

It is also possible to update new correction data each time by performing the same control as 4) to (118).
また、本実施例では負方向の移動時に補正を行なった
が、第8図に示すように正方向の移動時に補正を行なっ
てもよい。In this embodiment, the correction is performed during the movement in the negative direction. However, the correction may be performed during the movement in the positive direction as shown in FIG.

例と同等の結果が得られる。That is, after performing acceleration processing in the forward direction, the laser beam is moved by the correction value X pulses, and after recording, (K-
Move by the adjustment pulse of X), decelerate, and stop. In the printing in the negative direction, after the acceleration processing, after moving by K pulses for securing the correction area, recording is performed, and deceleration is stopped. As described above, even if the pulse is adjusted in the forward moving direction, the same result as in the above embodiment can be obtained.
次に、本発明の他の実施例を説明する。 Next, another embodiment of the present invention will be described.

で、電源投入時での負荷に対するズレ量Xが定まる。When the above processing is completed, P = Q should be satisfied in an ideal driving system. However, since the driving system is not an ideal rigid body, the eigenvalue Y such as a play is used as described above. (Points A to L and F to G in FIG. 11). Further, since the recording head H does not immediately follow the pulse given to the pulse motor 17, the switching position of the level of the HP sensor 4 is changed from the point C to the point D in the positive direction and to the point I in the negative direction. Q> P because of deviation from the point J to the point J. Therefore, assuming that this shift value is X, this value is considered to be equal in both the positive and negative directions, and is obtained by X = (Q-P-Y) / 2. Therefore, this is stored in the RAM 94 as a correction value (420). As described above, the shift amount X with respect to the load when the power is turned on is determined.
