Abstract

PURPOSE:To improve the operability of a attribute code in a repeated input mode by stopping the repeated input at a position where the attribute code is already supplied in a continuous and repeated input mode of the attribute code. CONSTITUTION:When an underline, for example, is supplied, an underline key 1a is operated to read the data out of a memory 7 designated by a cursor pointer CP. Then the presence or absence of an underline code contained in the data is checked. If no underline code is contained in the data, an underline code is added to the character code stored in the memory 7 designated by the CP. Then the CP is replaced and the data is read out of an input buffer 2a. If an underline code is detected, the similar processing is repeated. Here the clear signal is delivered to an input control part 2 if an underline code is contained in the character code stored in the memory 7. Thus all processes are through.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for inputting character attribute codes in Japanese LIET9 processors, typewriters, and the like.

[Prior art and its problems]

Generally, when manually adding attribute codes such as underlining and shading to a character code, if the attribute code input designation key is pressed continuously, the attribute code changes to character code 9.
is input continuously. Furthermore, when deleting an attribute code, is there an attribute code input specification key? If you press the button continuously, the attribute codes that have already been input will be deleted continuously. ,
Furthermore, if you want to add an underline code to the character code "C-F," specify the cursor at the character code "C" position, and then press the underline input designation key continuously to add the underline code. Repeat input is executed, and the underline code r is added in order starting from the character code C. Conventionally, the input designation key is immediately released after the operator visually confirms that the character code "F" has been input up to the 14th place. This requires excessive attention from the operator. If the release of the input designation key at the character code F position is delayed, the next character code '
The underline of G was often deleted, resulting in the state shown in FIG. 3(b).

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and in the continuous repeat input of the attribute code 9, the repeat input is stopped at a position where an attribute code has already been input, thereby improving the operability when repeatedly inputting the attribute code. The purpose of money is to improve.

[Key points of the invention]

In order to achieve the above object, the present invention provides continuous input of attribute code 9 if an attribute code already exists at the position where the attribute code is input, in a state where attribute codes are input continuously. It was designed to stop.

〔Example〕

FIG. 1 is a circuit diagram of a word processor. 1 is an input section having an underline key 1thf, and 2 is an input control section having an input buffer 2a. Key codes output in response to operations of various keys provided in the input section 1 are input to the input buffer 2a. Reference numeral 3 denotes a repeat state detection circuit which detects a state in which a key such as the underline key 1a provided in the input section 1 is pressed for a certain period of time or more, and sets the flip-flop circuit 4 to a set state based on the detection signal.

The set signal of the flip-flop circuit 4 is input to the input control circuit 2, and in response to this signal, the input control circuit 2 inputs the codes of the currently pressed keys into the input buffer 2a one after another.

s d Use the CPU to rewrite the code in the input buffer 2a.
It is read by the ad Out signal, and data input processing, editing processing, etc. corresponding to this coat 9 are performed.
The PU 5 outputs a clear signal to the flip-flop circuit 4 and the input control section. A dictionary 6 consisting of a memory corresponding to kana and kanji is connected to the CPU 5 and searches for kanji data corresponding to the input kana data. Furthermore, the CPU S stores writing data including kanji data after being converted to kana-kanji); the memory 7 stores character font patterns for display and printing, and programs for processing operations of the CPU. ROM 8, records data such as cursor pointer CP indicating cursor address 0, etc. 1, RA
M9 is connected. The cursor address in the cursor point CP specifies memory 7 as an address, and the character data (space,
(including all era titles, etc.) is displayed on the display section IO along with a cursor mark.

Furthermore, the character data in the memory z is printed by the printing section 11. Attribute code 9 such as underline is expressed using unused bits in the character code, and when the underline key 1 a f is operated once, the cursor pointer CP
After the underline code 9 in the character code ``in the memory z'' is set or reset, the pointer in the cursor pointer CP is incremented.

(2) Operation Figure 2 shows the CP in case you operate the underline key 1af.
It is a flowchart which shows the operation|movement of U2. To the data in memory 7 specified by cursor pointer CP in SI! The presence or absence of an underline code in the read data is detected in S2, and if there is no underline code, the process proceeds to S3, and the cursor pointer CP is
An underline code is added to the character code in the memory 7 specified by . After updating the cursor pointer CP in step 84, the data in the input buffer 2a is read out in step S, and it is detected whether this is the underline code 9 or not.

If it is the underline key V, the underline code is continuously input into the input buffer 2a, that is, it is a repeat input state, and in the next process S6, the next character code r is read out completely, In S7, it is detected whether or not this character code includes an underline code. If there is no underline code 9 in the character code, the process returns to S3 and all underline codes 1'' are added.Then, the process up to 87 is repeated in the same way, but in S7, the underline code is added to character code 9 in the memory. S8 if available
In this process, a clear signal is output to the input control unit 2, and all processes are completed.

When the clear signal is input to the input control unit 2,
If an underline code remains in the input buffer 2a, it is erased. However, the continuous repeat input of the underline code is stopped according to the processing result of step 37. In addition, in S5, when the underline key V in the input buffer 2 & is gone, that is, when the pressed state of the underline key 1m is released, all the processing ends. The processing of S, ~StS is the processing when an underline code has already been added to the character code P in the memory in the processing of S2, and in this case, contrary to the processing of 83 to S7, the underline code is added. Deletion processing is performed.

In this case, if it is detected in the process of S13 that the underline code in the memory is no longer present, the repeat state is stopped in the process of S8. Since the CPU 2 performs the above operation when repeating the underline key 1a, when the underline is repeatedly input from the position of the letter C in Figure 3 c&), the repeat input stops at the position of the letter F. , there is no risk of accidentally deleting the underline below the letter G.

In addition, in the embodiment, if an attribute code already exists at the attribute code input position, continuous repeat input is stopped and input processing is terminated. If the pressed state of the key is maintained, the input may be accepted again and the process starting from 81 in the flowchart of FIG. 2 may be performed. That is, in this case, the third
After the repeat input for adding an underline stops for a certain period of time at the position of the letter F in the figure (al), the repeat input for deleting the underline from the letter G follows.

〔Effect of the invention〕

As described above, the present invention can significantly improve the operability when repeatedly inputting attribute codes, thereby reducing the burden on the operator and preventing erroneous operations.
