Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character display capable of displaying characters with pronunciation collars.

In general, in a Teletex that has word processing functions, characters with pronunciation collars such as umlauts and carons corresponding to various foreign @ characters that are not in the ASCII code used in conventional Telex are converted into characters of the Teletex terminal. There is a demand to be able to display it on a screen. Therefore, in addition to many types of basic characters, all the character pattern information of each letter with a diacritic mark is stored in a character generator (ROM) K. Therefore, the capacity of the character generator will increase, and the capacity of the memory (VRAM) will also increase because the code number of the input character will be memorized and the character generator will be able to access it. There's a problem.

The present invention has been made in consideration of the above points, and it is an object of the present invention to provide a 5K character display capable of displaying various characters with pronunciation collars without increasing the memory capacity in any way.

The character display Itc according to the present invention includes:
Along with storing pattern information 11M1 of various basic characters in the character generator.

The pattern information of various diacritic marks is stored in the character generator 4 of the Vi2, and the pattern information of each character specified by the code is extracted simultaneously from each character generator and synthesized, and the synthesized pattern information is Based on this, the characters are displayed on a display with pronounced pronunciation.

At that time, regardless of whether the basic character is uppercase or lowercase, if the diacritic mark symbol of Oka-size is combined, for example, in the case of @1 (a), the balance of the lowercase letter raJ with a pronunciation collar is is bad, and in the case of the same figure (b), the balance of the capital letter rAJ with a pronunciation collar becomes unbalanced (especially in the case of diacritic marks such as sharp notes and umlauts 11 placed above basic letters) is a problem, and in the present invention, % [42
The character generator is provided with pattern information for each diacritic mark symbol for uppercase and lowercase letters, and the pattern information for each diacritic symbol for uppercase and lowercase letters is read out appropriately according to the basic character to create a well-balanced diacritic collar. It is possible to display characters on the display. Figure 2 shows the basics for creating character data with a pronunciation collar by synthesizing each pattern information of a basic character specified by a code and a diacritic mark symbol. An example of a typical circuit configuration is shown in the character generator 4 of %#il, for example, the pattern information of each camphor basic character used in teletex shown in the character code table of FIG. 3, and the second character generator 5. For example, the pattern information of the % wood phonetic note symbol shown in character code-4 in Figure 4 is stored in advance.In the character code table in Figure 4, 00H to OFH are the various pronunciations for uppercase letters. Musical note symbols) i, IOH to IFH respectively indicate various phonetic note symbols for lowercase letters of the same type.

From top to bottom, each diacritic note symbol is a depressed note, an acute note, and a sharp note.

In the configuration shown in Figure 2, first, the code signal sent from the input device (not shown in Figure 1) is a basic character (for example, A).
diacritic symbol (e.g. umlaut...)
The discrimination circuit 1 discriminates whether the basic character rAJ is the same, and the code signal of the discriminated basic character rAJ is stored in the first refresh Fuji memo II (VRAM) 2, and the code signal of the diacritic mark "..." is stored in the position corresponding to "mu" in the second refresh memory 3.Next, the code signals stored in each refresh memory 2.3 are simultaneously brought out by a control circuit (not shown), and the code signals are Each read code signal is given as an address to a character generator 4 for basic characters and a character generator 5 for diacritic marks. Further, each character getter generator 4.5 is given a row address by a row address curn 46, respectively. Therefore, the basic character rAJ e read out from each character generator 94°5
The data of each pattern of the diacritic mark symbol “°°” is sent to the OR circuit 7.
The logical OR is performed for each identical bit in the column, and the data is synthesized.

The synthesized data of the character "τ" with a pronunciation collar is converted into serial data by the parallel-to-serial conversion circuit 8, and character pattern data based on the serial data is obtained. Figure 5 shows the present invention. Here, under the control of the CPU 9, character pattern data is generated according to the input code qi, and based on the character data (character display on CRT). The part Is in the figure shows the character data generation part shown in Figure 2, and the %CPU9 is designed to have the function of the basic character/@child symbol discrimination circuit 10. , and its character data generation section ■
Smell 1: Refresh Island Memory 2 for basic characters
2. On each input side of the memory 3 for refreshing diacritic marks, there is a multiplexer 10 for appropriately switching between the basic character code No. 11 and the diacritic mark code signal.
11 are respectively provided, and each input 11 of the character generator 4 for basic characters and the character generator 5 for diacritic symbols is provided with each refresh island memory 2.

Therefore, the character design according to the present invention configured in this way (in the case of a spray, for example, the basic character "1" in uppercase) is
If you want to add the Guanyin symbol "/" to the ``/'' symbol and display it on the display, use 4 in the character code table in Figure 83.
The data of each character pattern is simultaneously viewed from the character generators 4 and 5 by specifying the basic character "mu" of 1H and the Kannon symbol "/" for the capital letter of 02H in the character code table shown in Figure 4. If you output and synthesize it, the CRT uiiffi will display a balanced capital letter F with an acute note.'' Also, add an acute note g ``/'' to the lowercase basic character ``1''. In this case, the character pattern data of the basic character ``61H'' and the lowercase Kannon symbol ``/'' without the code specification t are simultaneously extracted from the character generator 4.5 vCia and synthesized. If so.

A lowercase letter "i" with a well-balanced acute note is displayed on the CRT 1ili side.In the character display according to the above 1 invention, the first with a character generator.
