DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centering printer having a function of centering and printing a sentence on a sheet.

[0002]

2. Description of the Related Art Generally, in a document preparation apparatus such as a Japanese word processor, a drive roller and a driven roller for conveying an appropriately sized sheet along a predetermined sheet feeding direction on a conveying path. And a printing device including a print head that moves in a printing direction perpendicular to the paper feeding direction, and the paper feeding operation is performed every time one line is printed in the printing direction. Is performed and sentences are sequentially printed. Therefore, centering the text in the print direction of the paper is relatively easy, that is, it can be realized only by controlling the print start position of the print head.

On the other hand, in such a document creating apparatus, for example, as shown in FIG.
To the center 11 of the paper 11
It is also printed by centering on a. In this case, the vertically written characters (font data) 10 are rotated 90 degrees and printed on the paper 11 in the printing direction (horizontal direction). Must be centered.

Conventionally, in the centering printing method for performing this kind of centering, as shown in FIG. 6, the printing start position 10a in the printing direction of the vertically written characters 10 and the paper feeding direction,
That is, based on the upper right corner (upper left corner in the figure) of the vertically written character 10, the character 10 is set so that the character 10 overlaps the center of the paper 11 and the paper 11 is set before printing is started.

[0005]

Generally, such a centering operation can be performed more easily and accurately.
It is important for improving the function of the document creating apparatus and not wasting paper.

However, in the above-described conventional centering printing method, since the reference position and the center of the paper are different, the size of the character to be printed and the size of the sentence are taken into consideration with reference to the print start position of the character. Since printing is started after the paper is set by setting the paper, a considerable error actually occurs, and the paper setting work is repeated many times by trial and error until the vertical writing character 10 is printed at the center 11a of the paper. There is a problem that it must be done. In addition, when centering a wide variety of printable special characters, especially enlarged characters and sentences consisting of multiple lines, the print start position must be set based on the register according to the enlargement ratio and the number of lines. Therefore, the operation becomes more troublesome.

The present invention has been made in view of the above-mentioned conventional problems, and provides a centering printing apparatus capable of centering and printing a character such as a vertical writing character in the paper feeding direction of a paper by a simple operation. The challenge is to provide.

[0008]

In order to achieve the above-mentioned object, the centering printing apparatus of the present invention has a conveying means for conveying a sheet on a conveying path and a sheet for setting the sheet at a desired position on the conveying path. Sheet setting means, printing means having a print head for printing on the paper set in the transport path, and the width along the transport path of the text to be printed on one surface of the paper set in the transport path The calculating means and the conveying means are controlled so as to return the sheet set in the conveying path along the conveying path by a half of the obtained width, and the printing means is controlled so as to start printing on the returned sheet. And a control means for controlling the operation.

[0009]

When the document is printed by using the centering printing apparatus of the present invention by centering the document in the center of the paper feeding direction, first, the paper setting means is used to align the center of the paper with the print head. As such a sheet setting means, for example, a control mechanism including a manual handle which is interlocked with a roller constituting the conveying means, a switch for rotating a drive roller constituting the conveying means by an arbitrary amount, and the like. Should be used. Here, the calculating means obtains the width of the text to be printed on one surface of the sheet set in the transport path along the transport path. Then, the transport means under the control of the control means,
Load the paper set with its center aligned with the print head,
Only half the width obtained by the calculation means is returned along the transport path. As a result, according to the present invention, it is possible to set the paper based on the center position of the text instead of setting the paper based on the position of the text where printing is started as in the conventional case, and thus centering is performed. Such an error can be reduced, that is, the text can be accurately centered and printed in the paper feeding direction. Further, in this way, when performing centering, the operator need only uniformly align the center of the paper with the print head regardless of the type and size of the text to be printed.

The following examples of the present invention will further clarify such effects of the present invention, and further clarify other effects of the present invention.
