JPS60129267A - Printing system for letter and the like - Google Patents

Abstract

PURPOSE:To simplify controlling the printing of letters, etc., by properly varying the sizes of many kinds of letters by selecting plural letters generators to generate information of different kinds of letters. CONSTITUTION:Plural letters generator circuits 13 and 14 in which different kinds of letter types are stored are provided. An information of any type letters is read out on a proper command and printing is made on the information. Letters of scale factors not whole multiples can thus be printed selectively at any time and the freedom of selectivity for type and sizes of letters to be printed can be easily enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a printing method for characters used in word processors and the like.

Prior Art In conventional text processing devices, the same printing device is used to
In order to print a wide variety of character sizes at once, hardware work such as replacing the head was required. Also, even if you replace the head, wire dot printers
The font size was changed by increasing (or decreasing) the dot pitch, and the font itself was the same. In this type of conventional printing method, there is no problem if the reduction/enlargement is an integer multiple, but if it is not an integer multiple, the character shape may be distorted, and in order to prevent this deformation, It was a complicated process, and there were also problems with speed, etc.

Furthermore, in the conventional system, only two or three sizes of characters, approximately twice the height and twice the width, were available for selection.

An object of the present invention is to provide a method for printing characters, etc., which allows various sizes of characters to be selected at will and which is easy to control.

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

The printing method of a Japanese word processor equipped with a charge control type inkjet printer will be described below. In a Japanese word processor, characters are input from a character input device and stored in a text memory with each character hood. This character code is supplied to a character pattern processing section to generate a corresponding pattern and output it to a printer or CRT display.

Further, the character size is set for each print line, and a pattern is generated in accordance with this size command.

The size command in this example includes 24X24°32X3
There are instructions for 2, uppercase (double), and lowercase.

The inksheet printer also has a dot density of 32 dots/column. It has 32 levels of particle charging, and a high-voltage deflection circuit allows it to be
The printing dots are positioned by scanning in the row direction, and the printing head is moved in the row (horizontal) direction. The charging level and row direction of each particle are adjusted in two stages according to the lowercase/uppercase instructions, and the degree of overlap of adjacent particles is adjusted. Note that in the row direction, the recording timing in the running of the recording head is adjusted in two stages.

Next, the block diagram of FIG. 1 will be explained.

Reference numeral 10 denotes a character pattern controller, which is supplied with character code data and format commands for one line from a data processing section (not shown), and controls the generation of character patterns.

Reference numeral 11 denotes a character buffer 7 that stores the supplied character codes for one line, and transfers each character code via the controller 10 to a character pattern generation circuit to be described later.

A dot buffer 12 stores one line of character patterns supplied from the character pattern generation circuit, and is supplied to the inkjet printer drive circuit 20 via the controller 10.

13.14 is a character pattern generation circuit that generates a character pattern corresponding to the character code supplied from the character buffer 11, 13 is a circuit that generates a 24 x 24 dot pattern for one character, and 14 is a 32 x 32 dot pattern. This is a circuit that generates

Reference numerals 15 and 16 denote switching circuits, which select one of the character pattern generation circuits 13 and 14 according to a format command supplied from the data processing section.

Reference numeral 17 denotes a command register that stores format commands supplied from the data processing section.

Reference numeral 20 denotes a drive circuit for the inkjet printer, which includes a built-in print pan 77 for storing one line of pattern data supplied from the controller 10, reads data from this buffer 7 column by column, and controls printing. Also, depending on the command from the controller 10,
Performs uppercase/lowercase character bias control.

21 is an inksheet printer.

Next, the operation will be explained with reference to FIG. In FIG. 2, CG represents a character generation circuit.

(2) A format indicating which characters are to be printed is stored in the character pattern processing unit in advance from the character input device. The format includes
Basically 24x24 lowercase letters, 24x24 uppercase letters, 32x
There are 32 lowercase letters and 32x32 uppercase letters.

■ Input the desired characters from the character input device.

The characters input here are stored in the character processing unit as character codes, and also have format information set in ■.

■ When the character machine prints a character (sentence) stored in the character pattern processing section, the processing section adjusts the format of the character to be printed to the drive circuit 20, and prints 24 dots/column for 24x24. , 32x32, it is notified by giving a command that the data is 32 dots/column in 7 formats. Furthermore, depending on whether the letter is a lowercase letter or an uppercase letter, a command for specifying lowercase letter printing or uppercase letter printing is sent to the drive circuit 2.
Give to 0. The drive circuit 20 sets the print format by receiving the command.

■ The character pattern processing section selects either character generation circuit 13 or 14 according to the above format, and
Select either the dot character or the 32 x 32 dot character.

■ The character pattern processing section is the character generation circuit 13 or 1.
The character pattern read from 4 is transferred to the drive circuit 20.

(2) Through the above operations, it is possible to print four types of character sizes, 32-dot uppercase or lowercase letters, and 24-dots uppercase or lowercase letters, as printing results using the same printer.

■ In the above operation, each character pattern is
It is also displayed on the display device 22.

In addition to the formats shown in ■, there are double width, double height, and quadruple formats such as b, 24X24 lowercase/uppercase, 32X
It is possible to correspond to each of 32 lowercase and uppercase letters, and a total of 16 types of character sizes can be printed.

As detailed above, the present invention is equipped with a plurality of character generators storing different character formats, reads out character information in any format in response to an appropriate command, and prints based on this. This makes it possible to select and print characters at any time with a magnification that is not an integer multiple, and also allows for greater freedom in selecting the shape and size of characters to be printed. can.

Note that the present invention is applicable not only to word processors but also to any printing device or character display device, and the printing device is not limited to an inkjet type.
