Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device having a text memory function (hereinafter referred to as a text memory function) capable of storing a text (hereinafter referred to as a text) for editing and printing. This relates to the editing function of the typewriter.

Configuration of Conventional Example and Problems Thereof Conventionally, some electronic typewriters are provided with a text memory function of storing an input from a keyboard and performing editing, printing and the like. In most of these cases, if you add a new word in the middle of the text and the text content exceeds the margin of the line, you have to erase the data after that line and re-enter it on the next line. Instead, many operations had to be performed for editing, and the operability was low.

If there is a word at the end of the line, if you put a hyphen in this word and output it on two lines, it will be extremely difficult to read, and if there is a long space at the end of the line, you will have to be very careful when editing. If so, there is a problem that a space appears at the beginning of a line after a line break, the output result looks very bad, and it is wasteful.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention is to solve the above-mentioned problems of the prior art. When editing text in an electronic typewriter, there is data that exceeds the right margin at the end of the output line. It is an object of the present invention to provide an electronic typewriter having excellent editing operability that can automatically perform line ending processing in some cases.

Another object of the present invention is to provide a human-friendly electronic typewriter whose output result is difficult to read and does not look bad.

Means for Solving the Problems In the electronic typewriter of the present invention for solving the above-mentioned object, an input means for inputting character data or space data, and a storage means for storing the data input from the input means Output means for outputting a sentence composed of the data stored in the storage means, and discriminating means for discriminating whether or not there is data exceeding the right margin when the sentence is divided into lines and edited. If the data exceeding the right margin is character data, the word formed by the character data is moved to the beginning of the next line, and if the data exceeding the right margin is space data, the portion exceeding the right margin. Takes a description means to cut off the space data of and to provide a control means to move the word composed of the next character data to the beginning of the next line. .

Action The present invention takes such technical means. Therefore, when there is character data that exceeds the right margin at the time of editing, the word formed by this character data can be automatically moved to the beginning of the next line. Also, when there is space data that exceeds the right margin, the space portion that exceeds the right margin is truncated and the word formed by the next character data can be automatically moved to the beginning of the next line. Since the end-of-line processing can be automatically performed in this manner, it is possible to provide an electronic typewriter having excellent operability. It also enables left alignment of sentences.

Embodiment FIG. 1 is a configuration diagram for explaining the present invention, and FIG. 2 is a perspective view of an electronic typewriter according to an embodiment of the present invention. Reference numeral 1 denotes a main body, which is an input unit such as a keyboard unit 2, a display unit 3, a text input key 4, a text print key 7, a paper feed amount selection switch at the time of line feed 5, and an input unit 1 for an input character from the keyboard unit 2. Mode switch 6 for selecting whether to display on the display unit 3 (L / L: Line by Line position) or to output directly to the printing unit 11 which is another output unit (TPWR position). And so on. FIG. 3 is a detailed view of the keyboard unit 2. In addition to the above description, the backspace 2a, forward 2b, erase 2c, return 2d, space 2e, repeat 2f, left margin set 2g, right margin set 2h, tab set 2i. , Tab clear 2j,
Margin release 2k, tab 2l, shift lock 2m,
Shift 2n, numeric keys 2o to 2g of 1 to 9, reverse index 2x, index 2y and 36 other character keys are provided in the same manner as a normal typewriter, and perform an operation corresponding to each.

FIG. 4 is a block diagram of the present invention. Although the printing means 11 is not shown, the printing means 11 is configured to print using a ballpoint pen, and a pen left and right moving motor 9 for moving the ballpoint pen to the left and right. A target character is drawn by a line feed motor 8 for vertically moving the mounted paper and a vertical motor 10 for moving the pen up and down to put the pen on or off the paper. Further, the motors 8 to 10 are controlled by the control means 13, and the control means 13 reads the text input keys 4 provided in the keyboard portion 2 and the above-mentioned respective key inputs, and prints the operation according to the input. It is constructed so as to make 11 perform. Further, the control means 13 is connected to the storage unit 12, and writing, calling, etc. of character data into the storage unit 12,
The deletion and the like are performed, and the operation of displaying the contents of the storage unit 12 on the display unit 3 is performed. Further, in the control unit 13,
The content of the stored text or the content of the input text is divided line by line from the beginning, and words that are not in the margin are moved to the next line. After the process, the first word of each line is left. It is arranged on the margin so that the text content subjected to the processing can be displayed and printed. In addition, after the return input or at the beginning of the line other than the beginning of the text, the space is prohibited from being input, and is not used as the display or print after the above processing.

Next, the control unit 1 of the present invention will be described with reference to the flowchart of FIG.
The main points of No. 3 will be described. Normally, the program starts from start 14, reads another input from the text input key 4 or the keyboard unit 2, and executes the process of the typewriter up to step 15 according to the input.

When the text input key 4 is detected in step 15, the text number is designated by the numeric keys 1 to 9 of 2 to 2w in step 16. In step 17, the text corresponding to the text number is called from the storage unit 12, and is edited so that each line fits in the current margin, and in step 18, the first part of the text is displayed. Thereafter, when an input from the keyboard 2 is detected in step 19, it is determined in step 24 whether the input data is a space, and if it is not a space input, the input data is stored in step 29, Step two
In step 8, the same processing as in step 17 is performed, and in step 18, display is performed.

On the other hand, when a space input is detected in step 24, it is checked in step 25 whether or not the cursor indicating the character input position is located at the head (line head) of the line. 28, but if the cursor is at the beginning of the line, it is checked in step 26 whether the previous data is return. Here, if the data is a return, the same processing as described above proceeds to steps 29 and 28, but if the data is not a return, step 27
The buzzer sounds and the data in the space is not input. Further, although not described, a space input is accepted at the beginning of the first line. If no character is input from the keyboard section 2 in step 19, the process goes through steps 20 and 21 to check whether the text print key 7 or the text input key 4 is input.

When it is detected in step 20 that the text print key 7 is pressed, printing is performed in step 23, but each line is printed by the processing performed in steps 17 and 28, and when printing is completed, text mode is set in step 22. Is ended and the process as a typewriter is executed again. If it is detected in step 21 that the text input key 4 has been pressed, the text mode is ended in the same manner as described above.

Next, FIG. 6 shows a detailed flowchart of the editing process performed in steps 17 and 28 of FIG. When starting from step 30, first, at step 31, the address of the first character of the text in the storage unit 12 is designated for the variable P, and thereafter at step 32, every time the data at the address indicated by the variable P is called, at step 33. Whether the data is a return, or in step 34, the above step 32
It is determined whether or not the number of data called in step 3 is within the margin, and if it does not exceed the margin in step 34, 1 is added to the variable P in step 37 and the sequential storage unit 1
Call the data of 2. When the data exceeds the margin in step 34, in step 35, the address of the data of the space closest to the address of the storage unit 12 currently indicated by the variable P is regarded as the end of the line, and the address of the next character data is determined. Is the beginning of the next line. That is, when the data that exceeds this margin is character data, the word that this character data consists of is moved to the beginning of the next line, and when the data that exceeds this margin is space data, the part that exceeds the right margin is moved. The space data is truncated and the word formed by the character data after the space data is moved to the beginning of the next line. If the cursor is located at the address of the detected line in step 36, the process ends, but if the cursor is not located, the above process is continued until the address where the cursor is located.

On the other hand, when a return input is detected in step 33, the address of the return data is regarded as the end of the line in step 38, the address next to the return is set at the beginning of the next line, and the same processing as above is performed. Is being processed.

Next, FIG. 7 shows a part of the data stored in the storage unit 12. Now, data is stored from addresses 0 to 69, but when the data is processed by the present invention, it is printed as shown in FIG. However, LM indicates the left margin and RM indicates the right margin. Here, the word exceeding the right margin is moved to the next line, the space data at addresses 71 to 74 are discarded, and the spaces after the return (addresses 34 to 36) are not discarded.

Further, as described above, each line of FIG. 8 is displayed on the display unit 3 with the same contents as the printing.

EFFECTS OF THE INVENTION The present invention outputs an input means for inputting character data or space data, a storage means for storing the data input from the input means, and a sentence composed of the data stored in the storage means. Output means, determining means for determining whether or not data exceeding the right margin exists in the line when the text is divided into lines, and when the data exceeding the right margin is character data, the character Move the word that the data consists of to the beginning of the next line, and if the data that exceeds the right margin is space data, truncate the space data that exceeds the right margin and move the word that consists of the next character data to the next line. Since a control means for moving to the beginning of the line is provided, when there is character data that exceeds the right margin during editing, the word formed by this character data You can automatically move to the beginning of a line. If there is space data that exceeds the right margin,
Spaces beyond the right margin are cut off and the word formed by the next character data can be automatically moved to the beginning of the next line. Therefore, the present invention can provide an electronic typewriter which can automatically perform end-of-line processing and is excellent in operability. Further, since the output result is not difficult to read and does not look bad, characters can be added or deleted at the same time, and a human-friendly electronic typewriter can be provided.
