Abstract

PURPOSE:To print an underline, a side line and a cancelling line all of which continue even when a character-to-character pitch is different, by providing a font memory storing the combination of a character size and the character-to- character pitch, a line bit buffer for outputting a character pattern and an emphasis pattern to a printer in a superposed state. CONSTITUTION:When the character code read from a page buffer 13 has an emphasis pattern, said character code is substituted with the character pattern address of a font memory 15 to be stored in a line bit buffer 16. An emphasis control circuit 14 selects an emphasis pattern from 18 kinds of emphasis patterns on the basis of the character pitch and character-to-character pitch at that time to indicate an emphasis pattern address to the font memory 15. An underline, a side line and a cancelling line are distinguished and the writing positions thereof are indicated to the line bit buffer 16. The line bit buffer 16 superposes the font pattern and emphasis pattern read from the font memory 15 on each other to output both of them to a printer 17.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a printing output side outputting device that prints out characters outputted from a printing device by superimposing them with seven underlines, sidelines, erasure lines, etc. It is something.

[Conventional technology]

FIG. 4 is a block diagram of a conventional print output control device disclosed in, for example, Japanese Unexamined Patent Publication No. 55-124842. In the figure, 411 is a central processing unit (hereinafter referred to as CPLI).
(abbreviated as), 412 is a command, Dofritubufrotubu,
413i-! , character code line buffer, 411-j
Attribution bit storage area, 416H attribution clip flop circuit, 417 print control circuit, 418 paper feed control section, 419 character pattern memory, 420 vertical/horizontal rotation circuit, 421 selector, 422[ It is a character pattern buffer.

Next, the operation will be explained. First, the command flip-flop 412 is set by the horizontal writing start command or M rose start command from the CPU 411, the character code line buffer 416 stores the character code for one line, and the attribution bit storage area 414 is set for horizontal writing. This is set when adding an underline or a sideline in the case of Mi writing. In addition, underline information or sideline information is stored in the attribution bit storage area 414, and in the vertical/horizontal rotation circuit 420, when the signal of the command flip-flop 412 is vertical writing, it is stored in the character pattern memory 419. The signal χ is transferred, a predetermined character cordon for one line is rotated by 90 degrees, and then transferred to the character pattern buffer 422. On the other hand, print control circuit 4
At 17, paper feed control 1418U controls the paper feed V based on the information of the command flip-flop 412 and the attribution flip-flop 416, which performs printing control to output underline information or sideline information to the printer. In this way, you can draw a sideline on the right side of vertically written characters.

[Problem that the invention seeks to solve]

Conventional print output control devices are configured as described above, so if the pitch between characters differs in one line, underlines or sidelines may not be connected, and furthermore, paper feed χ may cause the paper to be erased. There were problems such as not being able to print included lines.

This invention was made in order to solve the above-mentioned problems, and it is possible to print erased lines as well as underlines, sidelines, and erased lines that are connected even when the pitch between characters is different. The purpose is to obtain a print output control device 2 that has the following characteristics.

[Means to solve problem Z]

The print output control device according to the present invention includes a font memory for storing forced patterns of a type determined by a combination of character size and inter-character pitch, a line bit buffer for superimposing character patterns and emphasis patterns 7, and outputting them to a printer device 4. Emphasis control circuit to control! It was established.

[Effect]

The font memory in this invention memorizes a character pattern and an emphasis pattern, and the emphasis pattern is a pattern of the seed part determined from the character size and the pitch between characters. I am registered. The line bit pattern is stored in a superimposed manner on each character pattern or emphasis pattern transferred from the font memory, has a capacity for plural characters, and is used for output to a printer device. Furthermore, the emphasis control circuit selects an emphasis pattern and controls the printing position of the emphasis pattern.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 11 is a central processing unit (hereinafter abbreviated as CPtJ), 12 is an intermediate buffer for temporarily storing data transmitted from the CP[Jl 1, 16 is a page buffer for storing data Z for multiple pages, and 14 is a page buffer for storing data Z for multiple pages. When the data stored from the page buffer 13 is an emphasis code, an emphasis control circuit selects an emphasis pattern coden based on the corresponding character size or pitch between characters; 15 is a font memory that stores character patterns and emphasis patterns; 16 is a font A line bit buffer 17 that stores character patterns and emphasis patterns read from the memory 15 for multiple digits.
is a printer device.

Also, Figure 2 shows the emphasis pattern stored in the font memory, character pitch is the pitch of the character, number of dots is the corresponding number of dots, and intercharacter pitch is the character interval (number of dots) in the figure. 0.4°8.12 dots are specified. Based on this combination, it can be seen that there are 18 types of emphasis patterns surrounded by circles. In the figure, 21 is the type of emphasis pattern, 22 is the character pitch, 26 is the character spacing, and 24 is the character pitch.
is an emphasis pattern. Furthermore, Figure 3 is an example of printing an emphasis pattern! In the diagram shown, the dashed line is the highlighted line.

In the figure, 61 is underlined, 62! ``I1. The side line, 66 is the erasing line.The operation of the 0th order will be explained.First, when the power is turned on to the printing device, the character pattern and character pattern are stored in the font memory 15 in Fig. 1 from the floppy disk or CPUI. The emphasis pattern is registered.At this time, the type of emphasis pattern is O in Figure 2.
There are 18 types enclosed in . Data for printing is CP
The data is transferred from U11 and stored in page buffer 16 via intermediate buffer 12. The emphasis pattern starts with an emphasis start command and ends with an emphasis pattern end command, and is stored in the page buffer 16 in a format with an emphasis pattern attached. Then, when the character code read from the page buffer 16 has an emphasis pattern, the character code is replaced with the character pattern address of the font memory 15,
Applicable character pattern? 0 read from the font memory 15 and stored in the line bit buffer 16 At this time, if there is an emphasis pattern, the emphasis control circuit 14 changes the character pitch and inter-character pitch of the character code at that time, as shown in FIG. Select the appropriate emphasis pattern from among the 18 types of emphasis patterns shown and specify the emphasis pattern address in the font memory 15.6o On the other hand, the line bit buffer 16 is used to distinguish between underline, sideline, and erasing. By which writing position (and eventually printing position)? specify. The line bit buffer 16 multiplies the font pattern read from the font memory 15 and the emphasis pattern by M and outputs it to the printer device 17. In this way, a printing result as shown in FIG. 3 is obtained.

In the above embodiment, a printing device is shown, but a word processor, a display device of a personal computer, etc. may also be used, and the same effect as in the above embodiment can be obtained.

Furthermore, combinations of emphasis patterns! As shown in Figure 2,
Even if there are many types of combinations, processing can be performed using the same method.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to print an emphasis pattern in a print output control device. Since it is configured with a font memory and a line bit buffer, there is no need to prepare a special computer, the device is inexpensive, and a flexible printing device can be obtained.
