Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a tab set control device used in a device having a document input mechanism such as a typewriter and a word processor.

[Prior Art and its Problems] Conventionally, the tab function in a typewriter, a word processor, etc. must be set in a tab setting mode before inputting data.

Therefore, conventionally, tab setting and changing operations are troublesome,
There was a problem of poor workability.

[Object of the Invention] The present invention provides a tab set target 1 immediately before data input.
An object of the present invention is to provide a tab set control device capable of automatically setting a tab position from a data input state of a line (one line), thereby making it possible to set and change tabs easily and quickly. And

[Points of the Invention] The present invention discriminates and holds the leading character digit position on one line of each data block for each data input and holds the tab position of the next line based on this position information. It has a means for determining and determines the tab position of the next line from the data input state of the previous line.
The tab position can be automatically set based on the data of the previous line without setting the tab in advance and considering the change of the tab set. Therefore, the work such as setting and changing the tab can be performed easily. It can be done quickly.

[Example] (1). Configuration of First Embodiment FIG. 1 is a block diagram showing the configuration of an apparatus according to an embodiment of the present invention.

In the figure, 1 is an input unit for inputting various data,
It is a keyboard unit equipped with data input keys and further function keys including a tab (TAB) key and a carriage return (CR) key. Reference numeral 2 denotes an input control unit that performs an input process of various data input from the input unit 1. Here, the leading digit position (leading character position) of each block of the input data is, for example, a space code (SP).
It has the function of detecting the leading digit position that is recognized from the code array state that includes. It should be noted that X and Y in the input control unit 2 are cursor pointers indicating the character development start positions on the display memory 5, respectively.

Reference numeral 3 is a line memory for temporarily storing the input data of one line (row) under the control of the input control unit 2.
Is a tab memory which stores tab codes for one line under the control of the input control unit 2.

Reference numeral 5 is a display memory in which a pattern of input data to be displayed is developed under the control of the input control unit 2, and a pattern development start address is designated by the cursor pointers X and Y in the input control unit 2. . A display device 6 controls the display output of the display data stored in the display memory 5,
For example, it is composed of a CRT display. A display control unit 7 displays the display pattern stored in the display memory 5 on the screen of the display device 6.

FIG. 2 is a diagram showing the relative positional relationship between the data stored in the line memory 3 and the tab code (marked with ▼) registered in the tab memory 4 based on the data in the above embodiment. , A group of character blocks, that is, a tab code (mark ▼) is written in a digit position in the tab memory 4 corresponding to the first character position of the word (the first character position of the character string following the space code (SP)).

(2). The operation of the first embodiment The data input from the input unit 1 is sequentially stored in the line memory 3 in the order of input under the control of the input control unit 2 in units of one line. Further, the above input data is also pattern-developed on the display memory 5 under the control of the input control unit 2 in accordance with the expansion start position designation of the cursor pointers X and Y, and is displayed on the display device 6 under the control of the display control unit 7. Is output.

Here, when the carriage return key provided in the input unit 1 is operated after the data shown in FIG. 2 is stored in the line memory 3, the input control unit 2 causes the tab memory to operate in accordance with the key signal. 4 is once cleared, and the first character position of each word of the data stored in the line memory 3 (that is, if there is a character code after the space code,
This position becomes the first character) is detected, and a tab code (mark ▼) is written at a digit position in the tab memory 4 corresponding to the position as shown in FIG.

After that, the data in the line memory 3 is erased, and the cursor pointers X and Y move to the first tab position (Y ← Y + 1, X) of the next line.
← TAB).

Next, when data is input again from the input unit 1, the data is stored in the line memory 3 in the same manner as described above, and each time the tab key is operated, the data is stored in the tab memory 4 and the tab code (marked with ▼) is stored. Tab set according to digit designation,
The cursor pointer moves to the next tab position.

In this way, the tab positions are automatically set sequentially from the data input immediately before on a line-by-line basis. Therefore, the troublesomeness of the tab setting operation is eliminated, and data input using the tab function can be performed quickly and smoothly.

(3). Configuration and Operation of Second Embodiment FIG. 3 is an explanatory diagram of the second embodiment. Here, the data stored in the line memory 3 is transferred to the tab memory 4 as it is by the operation of the carriage return key and written. Then, by operating the tab key, the leading character position of each word is detected from the data in the tab memory 4, and the cursor pointer is moved to the detected digit position.

Even in such tab processing, the troublesomeness of the tab setting operation is eliminated as described above, and data input using the tab function can be performed quickly and smoothly.

(4). Configuration and Action of Third Embodiment FIG. 4 is an explanatory diagram of the third embodiment, in which it is detected that the data is the first data input after the space code (SP) is input or the tab key is operated. , The tab code (▼ mark) is written in the digit position of the line memory 3 corresponding to the input digit position, and the tab code (▼ mark) stored in the line memory 3 is operated by operating the carriage return key.
Transfer to and write.

Even in such tab processing, the troublesomeness of the tab setting operation is eliminated as described above, and data input using the tab function can be performed quickly and smoothly.

(5). Configuration and Operation of Fourth Embodiment FIG. 5 is an explanatory diagram of the fourth embodiment. Here, tab memories 41, 42, 43, 44 for a plurality of lines (four lines in the figure) are provided, and The tab positions up to a plurality of lines before are stored in the tab memories 41, 42, 43, 44.

At this time, when one line of data is input to the line memory 3 and the carriage return key is operated, among the tab codes for a plurality of lines already stored, the tab code on the frontmost line (in the figure, the tab memory 44 The one-line tab code stored in (1) is erased, and the tab code for the newly input one-line data input is stored (in the tab memory 41 in the figure) instead.

Here, after specifying how many lines before the tab position,
When you operate the tab key, the cursor pointer moves to the tab position of the specified line.

With such a configuration, the tab positions over a plurality of lines can be easily set.

Although the CRT display is taken as an example of the control target in the above-described embodiment, the present invention is not limited to this, and other devices may be used.

[Advantages of the Invention] As described above, according to the present invention, the start character position of the character string data of the previous line is detected, and this position is automatically set as the input position of the next line, and the next line is set according to this setting. Since the cursor position is controlled, a special setting operation by the operator such as a tab setting operation can be omitted, the burden on the operator can be eliminated, and data can be promptly input on the next line.
