置ずれの程度はさらに大きくなるという問題点を有しそ
いた。By the way, in conventional printing processing devices, the printing medium used is often horizontally long and tends to be skewed.
Considerable positional deviation from the reference position also occurs depending on the operator's setting method. In particular, the insertion port and the output port of the printing medium are the same device, and an image scanner 1 is installed on the side facing the print medium.
In the case of an apparatus in which the paper is read at 1 and then printed by a printing means at the time of ejection, the positional deviation is added at the time of ejection, so that the degree of positional deviation becomes even larger.
そこで、本発明は以上の問題点を解決するためになされ

されたものである。SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and is aimed at minimizing the positional deviation from a reference position during printing by a simple means.

Printing means 3 for printing on the medium sent to the position
A device for performing printing processing comprising: a medium condition detecting means 4 for detecting a state of deviation of a printing medium from a reference position based on an image read by an image reading means 2, and a detected state of the deviation. A printing position correcting means 5 for correcting the printing position of the printing means 3 based on the above is provided.
被印字媒体は搬送手段ｌにより所定の基準位置に搬送す

が必ずしも同一ではなく。The printing medium is transported to a predetermined reference position by the transport means l. However, the printing medium is not necessarily transported exactly to the reference position, because the shape of the printing medium is not necessarily the same.

印字媒体の位置を機構的に修正することなく印字位置修
正手段５により印字手段３の印字位置を修正する。In addition, in order to smoothly transport the printing medium, a transport means l is used.
This is because a certain amount of play is required between the print medium and the printing medium. Therefore, when the printing medium is conveyed near a predetermined reference position, the image reading means 2 is used to print '! 4 Based on the image read by the means 2, the medium condition detection means 4 detects the state of deviation of the printing medium from the reference position, and corrects the printing position without mechanically correcting the position of the printing medium. The printing position of the printing means 3 is corrected by the means 5.
次に未発１１の実施例に係る印字処理装置を第２図に基

13 is a video memory and 16 is a recognition section, which constitute the image reading means 2. Further, 14 is a paper feeding mechanism;
Reference numeral 15 denotes a paper feed control section, which constitutes a conveyance means.

表される。The values of e and f are definition data of the printing medium and are transmitted by the L-rank device in advance together with other reading position information before the image scanner 1.1 reads the data. The deviation from the standard position is at the top left and right of the printing medium; 71 (a, b)

切な位置に印字できるように修正をする。On the other hand, the print position correction means 5 corrects the print data based on the skew amount and the lateral print deviation amount so that the print data can be printed at the most appropriate position on the printing medium.
この点について、さらに具体的に説明する。This point will be explained more specifically.

る。For example, let us assume that the reading density of the image scanner 11 is 10 lines/feature, a=45 dots, b=30 dots, C=10 dots, and the dimensions of the printing medium shown in FIG. f is preliminarily l = 1500 dots, e-1000
If the dot is given as f=50 dots, the amount of skew is given by the formula 0 (45-30)/1500=
1/100, and the horizontal printing deviation h is 1o+tooo/100=20 dots according to the equation (2).

であることから １００ドツト右へずれると縦方向の位

リンタを使用している場合縦方向の修正を行うことも考
えられる。Therefore, the printing position correcting means 5 determines the printing start position l of the numbering data by the printer 17 as the printing means 4.
Set the position to be 70 dots ((50 + 20) beat 2 dots), which is the length f (50 dots = 5 centimeters) from the left edge of the medium as a predefined reference position, plus the amount of horizontal printing deviation. Fix it. Also, the noise of robberies was 1/too
Therefore, if the image is shifted to the right by 100 dots, the vertical position will be shifted upward by 1 dot, so if a printer with high resolution is used, it may be necessary to perform vertical correction.
尚、Ｃとｄとから斜行量を求めることもできる。Incidentally, the amount of skew can also be determined from C and d.

斜行量に対する傾きの修正は行わない、また、縦方向の
印字ずれ量：は本例では明記しなかったが左端からの印

の必要がある。By the way, in this example, we use a dot printer with a size of about 7 mm/cm to print 10 characters of 24 dots vertically and 16 dots horizontally, so if we move the 7th character up by 1 dot, we can print according to the oblique line. However, from the viewpoint of the appearance of the print, the inclination is not corrected for the amount of skew, and although the amount of printing deviation in the vertical direction was not specified in this example, the printing position from the left edge; If the value of 1f is large, it will cause a problem and needs to be corrected.
尚、縦方向の印字ずれ星は下記の通りである。The vertical printing deviation stars are as follows.

11- [Effect of IJI] Thus, in the present invention, in order to accurately detect the deviation state of the printing medium from the reference position by the medium state detection means based on the image read by the image reading means, By providing a means for reading the deviation, the printing position of the printing means can be easily and accurately corrected by the printing position correction means without mechanically correcting the deviation.
