Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an English word processor and a Japanese word processor, and particularly to a word processor that simplifies editing operations such as moving, copying, and deleting character strings (sentences, clauses). This is a proposal for Setusa.

Processing operations such as moving character strings in a word processor are generally performed in the following steps.

(1) Move the cursor to the start of the character string to be processed.

(2) Press a predetermined function key, for example, a so-called range designation key or a processing key such as a movement key.

(3) Move the cursor to the end of the string to be processed.

(4) Press a predetermined function key, such as the above-mentioned range designation key or the OK key for instructing completion of range designation.

(5) For move or copy processing, move the cursor to the move or copy destination. (In the case of deletion, press a function key that instructs it, such as a key called an area deletion key. This deletes the character string to be processed.) (6) Press a predetermined function key, such as the one mentioned above. of
Press the OK key. As a result, the character string to be processed is moved to a desired destination and is also copied.

In such an operating procedure, it is troublesome for the operator to accurately move the cursor to the beginning and end of the character string to be processed, and it takes a considerable amount of time.

The present invention has been made to improve such poor operability, and the character string to be processed generally extends from the first character of a sentence after a line break, a full stop, or the next character to the last character of a sentence before a line break, a full stop, or a full stop. Focusing on the fact that the text is a string of sentences, clauses, etc. up to, the system is configured so that by positioning the cursor somewhere between these strings, that string can be specified as a processing target. The purpose of the present invention is to provide a word processor with improved convenience of operation.

The present invention will be described in detail below with reference to drawings showing an embodiment of a Japanese word processor. First, the functions of the word processor according to the present invention will be explained based on FIG. As shown in Figure 1a, four character strings (sentences) that all end with a period are displayed on the display, and the second character string "Summer continues to be hot." is to be processed. If you wish to do so, move the cursor to the position of any character in this character string, as shown in the figure, to the position of "i" in the illustrated example. When you press the character string specification key in this state, the control unit specifies that the character string where "i" is located is "The hot days continue in summer.", and the cursor moves as shown in Figure 1b. Move to the beginning of the next string, in the example shown, the space at the beginning of the line. Then, when you press the character string specification key again, the third character string "Autumn is the most comfortable season in Japan." is specified as the processing target, and the cursor moves to the fourth character string as shown in Figure 1c. This will move to the word "winter" at the beginning of the sentence. In this way, the character string "Summer is the season..." which is pressed by a required editing key, such as the movement key, is moved. FIG. 2 is a block diagram showing the configuration of the apparatus of the present invention. In the figure, 1 is a keyboard, which includes character keys such as kanji, kana, and alphanumeric characters, keys related to input text such as period keys, and space keys, and a line feed key that instructs line breaks, and instructs the movement of character strings. The cursor movement key includes a copy key for instructing copying, a copy key for instructing copying, an editing key such as a delete key for deleting, a cursor movement key for moving the cursor vertically and horizontally, and function keys such as a character string designation key unique to the device of the present invention. Inputs from the character keys, period keys, etc. on the keyboard 1 are encoded and stored in the memory 2. The cursor register 3 stores the position of the cursor on the display surface (CR¨T raster) of the display unit 7, and also stores the address of the memory 2 corresponding thereto.

The video RAM 4 stores character data to be displayed on the display section 7, and in this example,
It has a capacity of 6 lines of 10 characters. A controller 14 that controls this device writes the contents of the memory 2 to a video RAM 4, and the data written to the video RAM 4 is read out in response to a timing signal output from a display timing generator 5 and is read out as a character consisting of a ROM. The video is sent to the pattern generator 6.
The data read from the RAM 4 is converted into a signal with a pattern suitable for display on the display section 7. The data in the memory 2 is also read out to the character pattern generator 6 during printing by the printing section 9, where it is converted into a pattern signal and then given to the printing section 9. In this case, the timing signal is the print timing. is provided by generator 8.

The device of the present invention has a first position register 11, a second position register 12,
These hold the start and end addresses of the character string to be processed in the memory 2, respectively, as specified by the controller 14. The retained contents are cleared when the power is turned on or when processing is completed. The buffer 10 is a memory that temporarily stores a character string designated as a processing target.

The determiner 13 is for determining the start and end of a character string, and if the character code at the cursor position is a line feed code (000D ₁₆ in this device) or a period code (2123 ₁₆ in this device), the controller 14, and in other cases, outputs "0". The controller 14 controls these circuit elements, and includes a 16-bit microprocessor, a ROM storing a control program, and the like.

Next, the processing sequence of the device of the present invention by the controller 14 will be explained. When the power is turned on, the memory 2, video RAM 4, and buffer 10 of the controller 14 are cleared, and both position registers 11 and 12 are reset. The cursor is also set to the upper left corner of the display section 7. This position corresponds to the first address in the memory 2 where input characters are stored.

Then, the operator inputs sentences using the character keys and symbol keys, and it is assumed that the input of the four sentences (character strings) shown in Figure 1a is completed, and from the second sentence and the third sentence. Let us specify a character string as a target for processing such as movement.

First, by operating the cursor keys, move the cursor located at the position next to the period at the end of the four sentences to an arbitrary position in the second sentence, ``The hot days continue in summer.'' In this example, it has been moved to "i". In other words, it is at the third character on the second line, and the contents of cursor register 3 are correspondingly "13".

Next, the operator presses a character string specification key.
Upon this keystroke, the controller 14 starts control for specifying the character string to be processed. FIG. 3 shows a flowchart of this control. First, the state of the first position register 11 is checked. In this case, since it has been reset, the output of the determiner 13 is checked next, and the contents of the cursor register 3 are decremented by 1 until the output of the determiner becomes "1". As in the above case, the content of the cursor register 3 is 13 and the character code of "i" is the character code of the determiner 13.
When input is being input to , the output is "0", and cursor register 3 is decremented until the cursor moves to the period before "summer", which means that the content of cursor register 3 becomes 9. Since the device output becomes “1”, proceed to the next step.
The contents of the cursor register 3 are incremented by 1, and the contents of the cursor register 3 at this time, in this case 10, are written into the first position register 11. The contents of this first position register 11 represent the starting end of the character string to be processed. Then, necessary data is written into the video RAM 4 in order to display an appropriate start mark at the corresponding position, that is, the 10th character of the first line where the character "Summer" is displayed.

Next, the contents of the cursor register 3 are incremented by 1 until the output of the determiner 13 becomes 1. In this case, when the cursor moves to the end of the second sentence, that is, when the content of the cursor register 3 reaches 20, the output of the determiner 13 becomes "1".
In this way, when the determiner output becomes "1", the contents of the cursor register 3 at that time, in this case 20
is written into the second position register 12. The contents of this second position register 12 represent the end of the character string to be processed. Then, in order to display an appropriate end mark at the corresponding position, that is, the 10th character of the second line where the period is displayed, the video RAM
4, and increments the cursor register 3 by 1. Figure 1b shows the state of the display section 7 in this state. If you press an edit key such as a movement key to instruct movement in this state, the second sentence "Summer...continues" will be displayed. It will be transferred to the buffer 10 for processing, but here the character string designation key is pressed again. Then, since the first position register 11 has already been set at this time, the second position register 11
The data for displaying the end mark in the video RAM 4 corresponding to the contents of the position register 12 is erased, and the cursor register 3 is moved until the output of the determiner 13 becomes "1" in order to check the end of the next character string. It is incremented by 1, and when it reaches 1, the content is written to the second position register. In this case, when it reaches 37, which corresponds to the period at the end of the third sentence (the 7th character of the 4th line), the judger 1
3 output becomes "1" and predetermined data is written into the video RAM 4 so that an end mark is displayed at that position, and the cursor register 3 is incremented by one. Figure 1c shows the state of the display section in this state, and by pressing the required editing keys here, the second and third sentences will be changed to ``Summer is...the season.''
The character string is moved, etc. as a buffer 10
It will be transferred to. Upon completion of this process, the controller 14 clears the buffer 10 and resets the position registers 11 and 12.

Note that the input sentence example above uses punctuation marks,
Input using the character keys Move the cursor to the specified sentence In bulleted sentences that do not use punctuation marks, such as when pressing the character string specification key, the line feed key is operated at the end of each line and the line feed code is given to memory, so this Even in the case of a sentence like
The character string to be processed can be specified in exactly the same way as in the previous example. Also, in the case of an English word processor, a period "." is used instead of a period ".".
Of course, you can use the following code.

As described above, the word processor according to the present invention includes a means for moving a cursor, an operation means for specifying a character string on which the cursor is positioned as a character string to be processed, and a word processor for specifying a character string using the operation means. When an operation is performed, the start and end of the character string is detected by detecting a break in the character string, and the part between these is specified as the character string to be processed. The present invention has excellent effects such as being able to modify a character string to be processed with an extremely simple operation, improving operability and increasing input speed.
