Abstract

PURPOSE:To easily carry out vertical double em printing and quadruple em printing, in an apparatus for printing a figure letter by moving N pieces of vertical heads to a traverse direction, by connecting a hardware magnifying each vertical row of a letter pattern twice to a control part. CONSTITUTION:When there is a vertical double em or a quadruple em mode in the code of one line of a figure letter code sent out from a letter code receiving part 1, a printing head 3 is moved to a position to which the first vertical double em or the quadruple em mode in one line is indicated by the control part 5 and the figure letter pattern is read from a figure letter accommodating ROM2 to send the data of a vertical one row N bit to a double em hardware 10. In the double em hardward 10, the vertical N bit of the figure letter pattern is magnified to a vertical 2N bit. The control part 5 divides the magnified pattern into the upper half and the lower half and to send the upper data to the printing head part 3 at first. In this case, when an indicated mode is the quadruple em mode, data is transmitted two times continuously.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a graphic character printing device for printing Chinese characters for personal computers, word processors, etc.

Conventionally, this type of device had the power shown in the iJ1 figure.
is a graphic character storage ROM, (3) has N vertical keys, and by moving left and right and typing M times, NXMb it
The print head section prints the graphic characters (41G1), the paper transport section transports the 41G1 printing paper vertically, (5) stores the graphic character Noreen of the NXM dot corresponding to the output code of the character code receiving section (1) in the ROM. (2), a control unit that sends out the paper to the print head (3) and controls the left and right position of the print head (3) and the paper conveyance unit (4); be.

Next, the operation will be explained. A character code receiving section (1) receives a control code and a graphic character code such as JIS6226 from the outside and sends them to a control section (5). If the received control code is for print position control, move the print head section (3) left and right according to the contents of the control code, or use power to move the paper conveyor section (4) to move the paper up and down. A control section (5) controls paper conveyance. Furthermore, if the received control code is a print mode control code such as full-width or double-width, the print mode for subsequent graphic character codes is determined.

When receiving a graphic character code, the control unit (5) reads a graphic character pattern of NXM bits stored in association with the graphic character code from the graphic character storage ROM (2). For example, the full-width graphic character pattern of the character "Kan" is a 16 x 16 bit two-dimensional binary pattern P1 as shown in Figure $2.
For example, the character part is stored as a value of 1", and the background part as a value of O". The control unit (5) is this vertical example Nb1
The data of t is sequentially sent to the print head section (3) from the left side, and the print head section (3) is moved to the right by one dot. If the horizontal double-angle mode is specified, data is transferred to the print head section (3) twice in succession. The print head unit (3)≦j corresponds to the Nb1t pattern sent from the control unit (5) by the vertical N dot head.
3) Characters are printed by pressing the ribbon (6) between the paper and the paper. The printing ribbon (6) has a mechanism in which the ribbon is automatically fed each time a character is printed. 51
If the graphic character pattern P1 shown in FIG. 2 is printed, for example, in double-width width, a graphic character pattern P2 as shown in FIG. 3 is obtained.

Conventional graphic character printing devices are configured as described above, so when printing double-height or quadruple-width characters, the graphic character pattern for that purpose is stored in advance in the graphic character storage memory. This invention was made to eliminate the above-mentioned drawbacks of the conventional method. A graphic character printing device that can print double-height and quadruple-width characters from full-width character patterns during printing processing by installing simple software that generates double-height character patterns from S-turn full-width characters. is intended to provide.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 114 shows a graphic character printing device according to an embodiment of the present invention. In Figure 8, (1) is a character code receiving unit that receives graphic character codes and control codes, and (2) is a graphic character that stores graphic characters of vertical N x horizontal M dots corresponding to each of the received graphic character codes. Character storage ROM, +31 has N vertical heads, and by typing M times in the horizontal direction, NXM
The print head section that prints the dot graphic characters, (4) the paper conveyance section that conveys the printing paper up and down, and αG the control section (5
) is used to enlarge the vertical N bits of the graphic character pattern to 2N vertical bits using the double-width hardware connected to n. (5) is a control unit that corresponds to the output code of the character code receiving unit (1) when the control code instructs full-width or double-width.
Read the M-dot graphic character from the ROM (2) and strike the print head (3) M or 2M times to perform full-width or double-width printing, and the above control code instructs double-width or quadruple-width printing. In this case, a pattern of 2NXM dots is obtained using the upper ε double-angle hardware, and vertical double-width or quadruple-width printing is performed by striking the upper half or lower half of the pattern. 8 (6) is the print head (
This is the printing ribbon attached to 3).

Figure s5 shows an example of the configuration of the double angle hardware according to the present invention. 8 in the figure, ■ is an input register, (
2) is an output selector.

Next, the operation will be explained. The character code receiving section (1) receives a control code such as JI$6226 and a graphic character code from the outside and sends it to the control section (5). If the control code is a print position control code, the control unit (5) moves the print head unit (3) left and right or moves the paper transport unit (4) to move the paper up and down according to the contents of the control code. This controls the paper conveyance.

The control Is (5) has a line buffer for printing one line and can store one line of code in advance.
It determines the print mode code (full-width, double-width, double-height, double-width) in the line code, and if there is no double-height or double-width mode code, the control unit (5) corresponds to the graphic character code. The graphic character pattern stored with the corresponding graphic character pattern is read out from the graphic character storage ILOM (2), and the vertical 1? 'JNb i
Sending the data of t to the print head section (3),
Move the print head (3) one dot to the right. When double-width mode is specified, the print head (
Transfer data to 3) twice in succession. Print head section (
3) is a print head section (3) corresponding to the Nb1t pattern sent from the control section (5) by the vertical N dot head.
Characters are printed by pressing the ribbon (6) between the paper and the paper. The printing ribbon (6) has a mechanism that automatically feeds the ribbon approximately 1 step each time one character is printed.

If there is a double-height or quadruple-width mode code in one line of code, first print the upper half of the double-height or quadruple-width mode. The control unit (5) prints the graphic character pattern designated by the double-height or quadruple-width mode on the machine number that moved the print head unit (3) to the first position in one line where the double-height or quadruple-width mode is designated. Vertical I PINb continues to appear from the character storage ROM
Send the data of it to the double-angle hardware head.

The control unit (5) is located in the double angle hardware display in the gJ5 diagram.
The data transferred is stored in input register l.

The output of the input register (■) is connected to the input of the output selector (2), and is connected to the terminals A1 to A by the signal on the signal line that instructs the upper/lower side of the double angle from the control IS [5].
16 or input data to B1 to B16 is output selector @
The signal is output from the controller (5) and sent to the control section (5).

Therefore, in the control unit (5), the double angle hardware (1(1+
The upper part of the ζ double angle is specified, the data is read, and this data is sent to the print head 5 (3), and the print head section (3) is moved to the right by one dot. The specified mode is 4
In the case of double-width, data is transferred to the print head section (3) twice in succession. After the control 5 (5) performs this process for one line of code, the print head section (3) is returned to the printing starting point, the paper for N dots is conveyed upward, and the next line is printed.

That is, the control unit (5) reads the graphic character pattern corresponding to the graphic character code from the graphic character storage ROM (2), and transfers 11QN bits of vertical data to the print head unit (3) once in the horizontal direction in the case of full-width mode. In the case of double-angle mode, data is sent out twice in succession. In the case of double-height and quadruple-width modes, transfer this data to the input register of the double-width hardware αG, specify the lower half of the double-width to the double-width hardware aG, read the data, and then read the read data. It is sent to the print head unit (3) once in double-height mode, and twice in succession in quadruple-width mode. It is assumed that the print head section (3) is moved to a dot distribution as data is sent out. The control unit (5) performs this operation for one line of the hood, thereby performing full-width, double-width, double-height, and quadruple-width printing.

for example! If the full-width character P1 in Figure s2 is printed in double-height, it will become the graphic character pattern PS in Figure 6, and if it is printed in quadruple-width, it will become the graphic character pattern P4 in Figure 7.

As described above, according to the present invention, simple hardware for enlarging each vertical column of a full-width character pattern by a factor of two is connected to the control unit.
This has the effect of easily performing double-vertical and quadruple-width printing without using M.
