Abstract

PURPOSE:To clearly indicate the center of a printing paper, by printing a pattern at a central position on a paper when a printing head enters a predetermined range, based on the position of the head being printing and the size of the paper. CONSTITUTION:One half of the vertical size A (mm) of the paper is compared with the length Y (mm) from the top end of the paper to the line in which a printing head 1 is now printing. When the value of y satisfies the relation of the following expression o<a-y<l, the head is lowered by (a-y), where l (mm) is the line space, a=1/2A-1/2d and d (mm) is the vertical size of a printing pattern 100, and the pattern 100 is printed at the left end position M of the paper, whereby the pattern is printed at the center in the vertical direction of the paper. After printing the pattern 100, the head is lowered by l-(a-y), and a composition is again printed. The position obtained by lowering the head by l-(a-y) is the same as the position obtained by feeding the head by the line space l from the position at which the head has been printing before printing the pattern 100. Namely, the pattern 100 is printed when the pattern 100 can be printed at the center in the vertical direction of the paper through moving the printing head (in operation) by a distance not larger than the line space l.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a Japanese δB word processor, and particularly to a configuration for printing to clearly indicate the center of a sheet of paper.

[Technical background of the invention and its problems] Conventionally, when creating sentences using a Japanese word processor and storing the paper on which the sentences are printed, the center is determined by creating a crease on the paper, etc., and the paper is printed based on this center. I punched holes in it and stored it in a file. Therefore, it is necessary to crease each dose, which is time-consuming and has the disadvantage that the paper is creased.

[Object of the Invention] In view of the above-mentioned drawbacks, an object of the present invention is to provide a Japanese word processor capable of printing clearly in the center of printing paper.

[Summary of the Invention] The present invention provides a Japanese word processor that includes a print head position determining means for determining whether or not the print head is within a predetermined range based on the position of the print head currently printing and the paper size; The above object is achieved by including a control means for moving the print head to a predetermined position in the center of the paper to print an arbitrary pattern when the head enters a predetermined range.

[Embodiment 1 of the Invention An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a Japanese word processor according to the present invention. Microprocessor 2 on bus 1
, Kanji pattern memory 3, RAM 4, line buffer 5
, and a printer control device 6 are connected thereto. This printer control device 6 is connected to a printer 7@. RA~14 has a text data area 41 for storing text data and a work area 42 for the microprocessor 2. Furthermore, the first
In the figure, only the main components related to the present invention are shown.

Next, an explanation will be given of the operation of printing to clearly indicate the center of the printing paper according to this embodiment. FIG. 2 is a diagram showing a portion of a sheet of paper printed by the Japanese word processor shown in FIG. 1. Here, the vertical length of this paper is A (m),
The length from the top of the paper to the line currently printed by the print head 1 is y (In!n), the line feed width is 1 (#), and the vertical width of the print pattern is d (#). Under these conditions, the length from the top of the paper to the next line printed by the print head is V(
m), the following relationship holds true.

y=y=t...(1) Here a=1 2A -1/2 d-(2>, compare the length of the vertical half of the paper with the above y. At this time, the relationship between y and the following equation is When a satisfying value is taken, Q<a-y<p
(3) If the print head is lowered by (a-y) and the pattern 100 is printed at position M at the left end of the paper, the pattern 100 will be printed at the center of the paper in the vertical direction. That is, (
Satisfying the formula 3) means that the print head that is currently printing has come to a position where it can print pattern 100 at the longitudinal center point of the paper by moving the print head by two or less line feed widths. Therefore, in this example, pattern 100 is printed when pattern 100 can be printed at the vertical center position of the paper by moving the print head currently printing within a range that does not cause a line break.

After printing pattern 100, turn the print head to λ-
Lower it by (a-y) and print the text again.

Note that the position where the print head is lowered by E(a-V) is the same as the position where the line is changed by 1 during the line feed from t=(1 printed before pattern 100 is printed.

Incidentally, if the formula (3) is not satisfied, the print head is changed by the line feed width ボ as usual.

Next, the above operation will be explained based on the Japanese word processor shown in FIG. First, the microprocessor 2 learns the value of the length A in the vertical direction of the printing paper loaded in the printer 7 via the printer control device @ 6, and calculates the formula (2) based on this A to obtain a. This a is stored in the work area 42 of the RAM 4. Thereafter, the microprocessor 2 reads text data from the text data area 41 of the RAM 4 and sends it to the printer 7 via the printer control device 6 to start printing. During this printing, the microprocessor 2 calculates the length y from the top of the paper to the currently printed line using equation (1) each time there is a line feed, and calculates the length y from the top of the paper to the currently printed line.
and a stored in the work area 42 of RAM4 (
3) Compare based on formula. If this formula (3) is not satisfied, the microprocessor 2, via the printer control device 6, changes the print head at the top of the line feed and prints the next line. When formula (3) holds true, the microprocessor 2 calculates (a-y), controls the print head to be lowered by this value via the printer control device 6, and then moves the print head to the left edge position of the paper. Pattern 1 at vertical center position)
The printer control device 6 is controlled to print 00. Hey, this pattern 100 is in the text data area 41 of RAM4.
It is assumed that this is stored in advance. After the printing of the pattern 100 is completed, the microprocessor 2 calculates -(a-y), controls the print head to be lowered by the calculated result via the printer control device 6, and then resumes printing again.

According to this embodiment, since the pattern 100 is printed in the vertical center of the paper on which the text is printed, the pattern 100
Paper can be stored by punching holes based on 0, which saves time and effort and avoids problems such as creases in the paper.

In the above embodiment, a pattern 100 is placed at the center point in the vertical direction of the paper.
Although we have described an example of printing a pattern, it is also possible to print a pattern at the center point in the horizontal direction of the paper in the upper margin of the paper. Furthermore, in the case of double-stitch printing, a center fold mark can also be printed at the center point of the paper. Further, it is also possible to easily print punch hole marks at positions equidistant from the center position in the longitudinal direction of the paper.

[Effects of the Invention] As described above, according to the Japanese word processor of the present invention, when the print head enters a predetermined range based on the position of the print head currently printing and the size of the paper,
By printing the pattern at the center of the paper, it is possible to print clearly the center of the paper.
