Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character display method that can reduce the number of times the character size is specified.

Recently, systems have been developed that read out weather forecasts and other information from an information file set up at a center in response to a request from a terminal installed in a general household, and notify the user of the information.

In this system, it is necessary to change or add contents to the information file, and information input devices for this purpose have also been developed.

When displaying characters on the display device of the terminal, it is easier to see if the kanji characters are displayed in large size and the kana characters are displayed in small size, so it is necessary to input them into the information file at this size. However, in conventional input devices, large and small size designation keys are provided separately, and it is necessary to press the size designation key every time a change is made from kanji to kana or from kana to kanji, and the number of times the size designation key is operated is limited. There were many.

The purpose of the present invention is to eliminate such drawbacks, and the purpose is to provide an input panel for specifying a plurality of characters and character sizes, and a method for inputting data from the input panel according to the specified character size. In an information input device that has a character code generator that outputs the character code of a given character, and in which character sizes that can be specified for each character type are determined, multiple character sizes can be specified simultaneously from the input panel, and the input This is achieved by a character size determination method that outputs character codes for characters input from the board according to the priority order of display character size according to the character type.

The present invention will be explained below based on examples.

The present invention enables simultaneous specification of large and small sizes,
Additionally, the output character codes are prioritized according to the character type.

That is, for kanji, only large character codes are output, and for kana, small character codes are output with priority.

A system block diagram for this purpose is shown in FIG.

In the figure, PRO is the processor, B is the bus,
CD is a code generator, KB is a keyboard, CM is a code memory, CPG is a character pattern generator, VSG is a video signal generation circuit, KG is a cursor generator, and CRT is a display.

To explain the operation, when the character size designation key on the keyboard KB is pressed, this signal is notified to the processor PRO via the code generator CD. When the processor PRO receives this signal, it controls the code generator CD and the cursor generator KG to change the size of the cursor displayed on the display CRT to the specified size.

Thereafter, the characters input from the keyboard KB are converted into character codes of a specified size by the code generator CD, and then notified to the processor PRO.

The processor writes the notified character code into the code memory CM according to the cursor position.

The character pattern generator CPG sequentially reads the contents of the code memory and generates a pattern.
Input to video signal generation circuit VSG.

The display CRT displays kanji and kana by combining signals from the video signal generation circuit VSG and the cursor generation section KG, and also displays the characters input from the keyboard KB in sequence at the cursor position.

Figure 2 shows details of the code generator CD.

In the figure, CSR is a command storage register,
STR is a statement register, KCT is a key code conversion circuit, SGT is a small and figure conversion circuit,
LST is large and small conversion circuit, OCT is external character code conversion circuit, RBR is read buffer register,
IF is an interface circuit, and the same parts as in FIG. 1 are given the same symbols.

When the character size is designated from the keyboard KB, this signal is input to the key code conversion circuit KCT via the interface circuit IF.

The key code conversion circuit KCT converts the code and inputs it to the statement register STR.
The contents of the statement register STR are input to the processor PRO via bus B, and the processor determines whether the contents are a character code or a function code. If it is a function code, this code is input to the command storage register CSR via bus B.

The contents of the command storage register CSR are sent to the key code conversion circuit via the interface circuit IF.
KCT, small and graphic code conversion circuit SGT, large and small conversion circuit LST, external character code conversion circuit
Input into one of RBT and enable conversion output.

In other words, if the specified code entered from the keyboard KB is "large" for displaying kanji etc.
If the key code conversion circuit KCT is "small and graphic" for displaying kana, figures, etc., the small and graphic conversion circuit SGT is "large and small" for displaying kana, kanji mixed sentences, etc. For example, it is input to the large and small conversion circuit LST, and if it is a non-standard character, it is input to the non-standard character conversion circuit OCT.

After that, the characters entered from the keyboard KB,
The graphic signal is input to the conversion circuit into which the designated code is input.

The output of this conversion circuit is the statement register
It is input to the processor via STR and/or read buffer register RBR.

Here, each conversion circuit is constituted by a read-only memory, and is addressed by a signal from the keyboard, and performs code conversion by reading the contents of the location corresponding to this address. Therefore, for example, when "large and small" is specified and a Kanji key is pressed on the keyboard KB, a signal corresponding to the pressed Kanji key is input to the large and small conversion circuit LST as an address signal.

If a large character code is stored in a position corresponding to this address, the large character code will be output.

When a kana key is pressed, a signal corresponding to the pressed kana key is input as an address signal.

As mentioned above, if a small character code is stored at this address position, the small character code will be output.

This eliminates the need to press the size designation key each time a kanji is changed to a kana or a kana is changed to a kanji.

As described above, according to the present invention, it is possible to specify a plurality of character sizes at the same time, and since a priority order of character size is given to each character type, it is possible to reduce the number of times of size specification.

The output of the key code conversion circuit KCT is input to both the statement register STR and the read buffer register RBR because the number of bits output from the key code conversion circuit KCT is large and one register does not have enough capacity. It is.
