Abstract

PURPOSE:To legibly print letters whose lower part is partly protruded downwards by a method in which when letters to be printed by projecting them downwards from a usual given area, an information of such kind of letters is judged and only one line of (n) is fed. CONSTITUTION:All the patterns of large and small alphabet letters are housed in a 7 X 7 character generator 38. On the other hand, the information of letters is stored through a decoder 30 into a printing buffer 31, and when a detector 32 is ready to judge whether the letter information is any one of g, j, p, q, and y, (1) representing it is stored in a control buffer 33. A pattern corresponding to the letter information coming from the printing buffer 31 comes from the character generator 38, the information coming from the control buffer 33 arrives through flip-flops 34 and 35, and when there are letters to be printed are projected downwards, they are line-fed and printed downwards.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing method, particularly when characters printed within a predetermined area and characters printed extending below this area are mixed and printed on the same line. Regarding the method.

As shown in Figure 1-), the alphabet letters include those that fit within a predetermined area, such as the uppercase letters A, B, C, etc., and the lowercase letters g*L psq, y.
In some cases, a part of the character protrudes downward from the predetermined area.

Conventionally, there have been two methods for printing these alphabetic characters on the same line.

That is, in the first method, when printing with a dot e-matrix printer, when general characters such as A, B, C, etc., and characters that fit within a predetermined area are composed of 7 x 7 dots, this method is used. Some of the characters protrude from the specified areag
+L P+ q+ In order to print the protruding portion of Y, a 7×9 area was prepared as shown in FIG. 1(b).

However, this method requires 9 rad pins for printing and 9 pins for a circuit to drive the head pin, and the character configuration in the character 9 generator to generate characters must also be 7 x 9. , has the disadvantage of a complicated configuration.

As a second method, g as shown in FIG. 1(c).

j+ ps q* The font was shortened so that Y did not protrude from the predetermined area, but this had the disadvantage that it was difficult to read because the cursive character was different from normal printing.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printing method that solves these conventional drawbacks, has a simple structure, and does not make printed characters difficult to read.

According to the present invention, such a purpose is achieved by mixing a first character printed within a predetermined area and a second character printed downwardly from the predetermined area on the same line. In the printing method, this is achieved by starting a new line by 1/n lines after completing the printing of the first character, and then printing the second character.

An embodiment of the present invention will be described below with reference to the drawings. Second
The figure shows the character structure in the character generator according to the present invention as characters At Bt gv hK').

In this example, the character structure is 7x7, including uppercase letters A, B, ... middle and lowercase letters g.

Place h as shown in the figure.

An embodiment of a printing system equipped with such a character fist generator will be described with reference to FIG.

In the following, the case of printing a single @Tel@phone will be described.0 Note that FIG. 4 is a flowchart showing the operation of the system of FIG. 3. First, when information arrives at the decoder 30, the decoder 30 decodes this information to determine whether it is character information, and if it is character information, stores it in the print buffer 31. , Printing (Zuffa 3)
1. On the other hand, the incoming character information is stored in gv
The detector 32 determines whether or not gv L pt Q+ 3
If the character is either ', 11'' is output, and if it is any other character, 10'' is output.0 Therefore, when the character information of @T'' arrives, it is stored in the print buffer 31 as described above, and gv L
pt qt )' l indicates a character other than '
l011 Kacontrol Bats, 0 stored in 33
Similarly, when the character information of 1e'', 1'', @e''' arrives, these are decoded and fct's are printed as 273
1, the storage address "o" is stored in the control buffer 33.

Next, when the character information of ``''P# arrives, the detector 32 becomes 1.
7 lags of 1" are placed in the control buffer 33. Character information ti, which has arrived in this way as shown in the figure,
Stored in print buffer and control buffer.

At the same time, the output of the detector 32 is given to the flip-flop 34 and 35, and from the flip-flop 34 there is g=L g, j, 1) #
(Information indicating that the character information other than L and 7 is 6 is input to the printer control circuit 36.
In the case of “phone”.

Since the clip flops 34 and 35 are both @l'', print start information arrives and print command 3 is sent from the decoder 30.
) is given to the printer control circuit 36, the printer control circuit 36 gives a space drive command to the space control circuit based on the output 11'' of the free lag frog 35 to move the print head in the printing direction, and also moves the print bar v77). Look at the contents of the knee control buffer and notice the first characters ``T1'' and ``O''.
The information of T'' is sent to the character generator 3B.

The character generator 38 inputs the information for printing "@T" to the printer control circuit, and outputs the print head drive signal using the print tying signal sent from the printer control circuit. Print head dryer I (feeds to 39 and prints one character T.

The force that causes s, l, and e to be printed in the same way! .

In the case of p, @1'' is set in the control buffer 33 [
Therefore, the printer control time [3] that identified this
61; m space control circuit 40 K treats p as a space and skips the print head by Vh1 characters and does not print.

It is printed in the same way as the Tole printed before the next h expansion.

Next, based on the output @1' of the flop flop 34, the printer control circuit 36 controls the line feed control circuit 4.
Give a small line feed command 42 to 1, line feed, +II end, l1all is set in the control buffer, the tail print buffer data is a space, and “1# is printed as character data in the same way as the output @l# of the Noritsubu flop 35. Therefore, in the area that was previously made a space, T・lsho
It is shifted downward by one line l/n (n is an integer) from me, and p is printed at the 9th position. As a result, the character generator 3 stores all the characters in the structure of ``FX7'' and generates K g a j , p-q as shown in FIG. 1(a).
It is possible to print characters, such as e7, in which a part of the character protrudes toward the F side compared to ABC, etc.

Similarly, in the above embodiment, when printing a character whose content is "@0" in the control buffer 33, a statement # whose content is "l" is printed.
Although it is treated as Company F space, 1, for example, -1 of - may be printed. Also, an example of printing with printability is shown.
It is obvious that the present invention can be applied to the case of bottles. Furthermore, even for characters with umlauts and underlines, such as A, the above-mentioned small line break is performed multiple times. .

Can be printed.

As described above, according to the present invention, the capacity of the character generator is reduced, and the number of pins of the print head and the driver circuit for driving the print head are reduced, so that the structure is simplified.
