Abstract

PURPOSE:To minimize key operation when the same code is repeatedly inputted by studying the display order of a code picture in a documentation device and displaying the newest selected code picture in priority. CONSTITUTION:When a code input processing program 31 is started, a code picture indicated by the leading code in a code picture selecting order table 43 is selected from a code dictionary 44 and transferred and displayed to/on a display buffer 42. If an objective code exists in the displayed code picture, a numeral key indicating the code position is depressed, and when no objective code exists, a conversion key is depressed. When the conversion key is depressed, the table 43 is again referred and the succeeding code picture is displayed. When the numeral key is depressed, the objective code is extracted from the code picture stored in the display buffer 42 and written on an input pointer position of a document buffer 41 and the table is updated so that the No. indicating the code picture in displaying is arranged on the head.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Application of the Invention The present invention relates to a method for selecting symbol screens for units, academic symbols, Greek letters, etc. in a document creation device.

[Background of the invention]

Generally, when creating a document with a document creation device, the same symbol is often input repeatedly in the same document, however, with conventional document creation devices.

Symbol screens can only be displayed in the order in which they are registered in the symbol dictionary, so when selecting a symbol screen later in the symbol dictionary, it requires a lot of manual effort each time, for example, when selecting a conversion key. It has the disadvantage that it is very difficult to operate (pressing the button many times).

[Purpose of the invention]

An object of the present invention is to improve the operability when inputting symbols in a single document creation device.

[Summary of the invention]

The present invention learns the selection display order of symbol screens.

By displaying the most recently selected symbol screen first, the keystroke effort required when selecting a symbol screen is minimized.

[Embodiments of the invention]

FIG. 1 shows an overall block diagram of a document creation device to which the present invention is applied. In FIG. 1, various function keys, character keys, etc. are installed on the keyboard IO, and among them, symbol keys and conversion keys are related to the present invention. The symbol key is used to change the mode to symbol input mode, and the conversion key is used when the symbol you want to input does not appear.

Used to call the next symbol screen. keyboard 1
The characters entered by the key operation above 0 are sent to the central processing unit 2.
Analyzed and processed in 0, stored in code format in memory (RAM) 4
It is stored in the document buffer 41 in Q. In parallel with this, central processing bags! ! 20 is a display device for displaying data in the document buffer 41! ! 50 display screen potentials and transferred to the display buffer 42, and the data in the display buffer 42 is supplied character by character to the display device 1150 for display. The programs necessary for the processing of the central processing unit [20] are stored in memory (ROM).
) 30, and one of the programs is a symbol input processing program 31 according to the present invention. In addition to the document buffer 411 and the display buffer 42, the memory 40 stores 9
Symbol screen selection order table 4 related to the present invention
3 and a symbol dictionary 44.

The symbol screen selection order table 43 indicates the display order corresponding to each symbol screen, and the symbol input processing program 31 refers to the symbol screen selection order table 43 to select the symbol dictionary 4.
The symbol screens are selected and displayed in sequence from step 4. Furthermore, once the desired symbol is selected.

Next, the symbol screen selection order table 43 is updated so that the symbol screen is selected first.

FIG. 2 shows the processing flow of the symbol input processing program 31. The symbol input processing program 31 is started by pressing a symbol key on the keyboard 10. When a symbol key is pressed.

The symbol screen indicated by the head of the symbol screen selection order table 43 is selected from the symbol dictionary 44, transferred to the display buffer 42, and displayed! ! 50 (step 101), and the operator looks at the displayed symbol screen and presses the numerical keys or conversion keys on the keyboard 10 (step 102).

That is, if there is a desired symbol in the displayed symbol screen, the operator presses the number key indicating the position of the symbol, and if there is no desired symbol, the operator presses the conversion key.

To determine whether this key is a numeric key or a conversion key (Steps 103 and 104), when the conversion key is pressed, refer to the symbol screen selection order table 43 again and select the first symbol screen from the symbol dictionary 44. Display (step 105)
. On the other hand, when a number key is pressed, 1 display buffer 42
The target symbol code is extracted from the symbol screen stored in the symbol screen and written to the input pointer position of the one-document buffer 41 (step 106). , and updates the symbol screen selection order table 43 so that the number (ID) indicating the currently displayed symbol screen comes first (step 107).

Therefore, when the symbol key is pressed next, the most recently selected symbol screen will be displayed first.

〔Effect of the invention〕

According to the present invention, by learning the display order of symbol screens in a document creation device and displaying the most recently selected symbol screen first, it is possible to minimize key operations when repeatedly inputting the same symbol. .
