Abstract

PURPOSE:To eliminate the need to provide an input part with individual keys or switches corresponding to a start control symbol and an end control symbol and to specify the start and end of a character type even when a user is aware of the character type by judging and inputting the start and end control signals of the character type automatically by operating the same key. CONSTITUTION:A character type control symbol decision means 7 decides whether a character symbol code is a character type control signal or not. When the input character symbol is the character type control symbol, the character type control symbol decision means 7 decides whether the character type control symbol is registered in a storage part 6' by using a storage means 5 in the backward order from the position where a cursor is currently. A charac ter type start/end decision means 8 operates according to decision output, a character type start/end control symbol changing means 9 substitutes the input character type control symbol with the character type start or end control symbol according to the output of said character type start/end decision means 8 and the input character symbol code sent from an input part 1', and the stor age means 5 registers it in the storage part 6'.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an editing device for a printing device that is equipped with a device that facilitates specifying the printing type of characters and symbols.

BACKGROUND OF THE INVENTION Conventionally, in a printing device equipped with a display device, when specifying underlined characters or bold characters, move the cursor in front of the character you want to make into the desired character type.
By pressing the character type designation key at that position, a symbol 28 indicating the desired character type is displayed on the display device 3. Then, move the cursor to the character where you want to end the desired character type, and at that position,
By pressing the character type specification key again, symbol 2
8 was inserted at the position of the cursor, and a display as shown in FIG. 4 was made.

Problems to be Solved by the Invention However, in such editing work, when specifying a character type, the start and end of the character type must be specified using separate keys, or the range that can be displayed at one time on the display unit is limited. When inputting a long sentence that exceeds There was a problem that unless you memorized the character type start/end declaration operations, you would not be able to do it.

Means for Solving the Problems The editing device of the printing device of the present invention automatically converts the character type control symbol inputted from the input section into a start control symbol and an end control symbol based on the already input character/symbol data. This is to replace it and display it on the display unit.

Function: The editing device of the printing device of the present invention automatically determines and inputs character type start and end control symbols with the same key operation. It is not necessary to provide a separate key or switch on the input section, and when you want to specify bold or underline printing over several lines, the user is aware of the character type at the current cursor position. Even if you do not, you can specify the start and end of a character type.

Embodiment Hereinafter, as an embodiment of the present invention, an editing device for a printing device will be described with reference to the drawings.

First, FIG. 1 is a block diagram of a printing device equipped with an embodiment of the present invention. 1' is a human power section, and the character/symbol code inputted from the human power section is stored in the storage section 6' by the storage means 5, and whether the character/symbol code is a character type control symbol or not. If the input character/symbol is a character type control symbol, the character/symbol is determined by the determining means 7, and if the input character/symbol is a character type control symbol, the first number is determined from the memory section 6' by using the memory means 5, and the starting number is determined by going backwards from the current cursor position. To,
The character type control symbol discriminating means 7 determines whether a character type control symbol is registered, and the character type start/end discriminating means 8 is activated in accordance with the output thereof. The character type start/end control symbol changing means 9 replaces the input character type control symbol with the character type start/end control symbol according to the input character/symbol code coming from the input section 1', and stores it in the storage means 6. is registered in the storage unit 6'.

When a print command code such as a carriage return is received from the input unit 1', the storage unit 6 reads out the unprinted character data from the storage unit 6' from the beginning and prints it out by the printing unit 2. In this case as well, The character type control symbol determining means A determines whether the read character code is a character type control symbol, and if it is a character type start/end control symbol, the printing character type changing means 10 changes the printing character type. This is changed and recorded in the printed character type storage section 12 using the printed character type storage means 11. If the read character code is not a character type control symbol, the character type changing means 1Q changes the character code stored in the character type storage unit 12 to the character type according to the character type read from the print character type storage unit 12. Add type information and
It is sent to printing means 2.

FIG. 2 is a circuit block diagram showing a specific configuration example of the present invention. Reference numeral 1 denotes a keyboard switch which is a character/symbol input section, and a microcomputer 16 controls storage means 5, character type control symbol discrimination means 7, character type start/end discrimination means 8, and character type start/end control symbol changing means. 9, a part of the printed character type changing means 10, the printed character type storage means 12, and the display means 4 are realized.

The RAM 6 is used to store character codes stored by the storage means 6 and character types stored by the printed character type storage means 11 at the same time. The liquid crystal display 14 and the liquid crystal display controller 13 are used to display character codes read out from the RAM 8 by means of storage means.

FIG. 3 shows a control procedure for microcomputer processing. First, in step 16, it is determined whether or not a character type control symbol has been input, and in step 17, the character code located before the cursor position is read out. Whether the read character code is a character type start control symbol or not Step 18
If it is a character type start control symbol, step 23
If not, the process proceeds to step 19, where it is determined whether the read character code is a character type end control symbol, and if it is a character type end control symbol, Proceed to step 22 to output the character type start control symbol, otherwise step 2o
Proceed to. In step 20, the cursor pointer is decremented by 1 and a stamp number is output, but if not, the process returns to step 17 and the above operations are repeated.

FIG. 6 to FIG. 9 show specific operational examples during display of the present invention. First, when characters/symbols are displayed as shown in Fig. 6, the character type start control symbol is set to 24, and when the kernel 25 is in the position as shown in the figure, when the character type control symbol is input from the input section, As shown in FIG. 7, a character type end control symbol is automatically entered at the position where the cursor 25 was, and the cursor 25 is moved one position to the right.

As shown in FIG. 8, when characters/symbols are displayed on the display 3, the character type end control symbol 26 and the cursor 2
5 are in the positional relationship as shown in the figure, when a character type control symbol is input from the input section, a character type start control symbol 27 is input and displayed as shown in FIG.

Effects of the Invention As described above, when selecting and specifying a character type such as a bold or underline character, the editing device of the printing device of the present invention can change the character type start control symbol or , it is possible to automatically input the character type end control symbol, so there is no need to perform a different input operation to specify the character type, and especially when specifying underlined characters or bold characters. Even if the data spans several lines, or if the character/symbol data is displayed on a display that is not capable of displaying it all at once, the user can easily To automatically control the start and end of character type without being aware of the character type. Also, when you enter a character type control symbol, it is automatically determined whether it is a start or end control symbol, and then input and display it, so you can clearly see the character type at the current cursor position. This is extremely advantageous in practice.
