Abstract

(57) [Summary] [Object] An object of the present invention is to provide an electronic device capable of promptly moving the cursor to the right of the rightmost character position (excluding spaces) in a line. [Arrangement] A display unit (6) for displaying a document, a cursor position storage unit (7) for storing a cursor position on the display unit (6), and an input unit (2) having a specific key (3).
When the specific key (3) is input, the position of the character (excluding space) at the rightmost end of the line where the cursor is currently located is detected based on the position information in the cursor position storage unit (7). At the same time, a main controller (1) for changing the contents of the cursor position memory (7) to position information indicating the right side of the detected position is provided.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an electronic device.

[0002]

[Prior Art]

 Conventionally, a device that can automatically set tabs every several digits without an operator performing tab setting, or a device that sets tabs at both ends when the number of characters that can be entered in one line is set (for example, Japanese Patent Laid-Open No. 2000-242242) JP-A-59-65339) is known.

This function is generally adopted in electronic devices having a word processor function, and is very convenient when moving the cursor to the beginning or end of a sentence.

[0004]

[Problems to be solved by the device]

 By the way, such a tab function is basically for quickly moving the cursor to a position desired by the operator to improve the input speed.

Such a desired position is often the final character position in each line (the rightmost character position in the case of a horizontally written document), but this position is not always the predetermined spacing position or the beginning of a sentence as described above. In many cases, the position does not match the end position of the sentence, but does not match the position at the end of the sentence. Therefore, when trying to move the cursor to the desired position using the conventional tab position, first use the tab function to move once to the tab position near the desired position, and then use the cursor movement key. It was necessary to move the cursor one character at a time, which was very inconvenient.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above point, and its structural features are a text memory in which a document is stored, a display unit for displaying the document in the memory, and a specific position on the display unit. A cursor position storage section for storing a cursor position for inputting, a input section having a specific key, and a main control section for controlling each of the above sections are provided, and the main control section receives the specific key from the input section. Then, the final character position in one line of the document where the cursor is located is determined based on the position information in the cursor position storage unit, and the position information in the cursor position storage unit is changed based on the determination result. It is in .

[0007]

[Action]

 According to such a configuration, the cursor can be quickly moved to the last character position in one line.

【Example】

 FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, (1) is a main control unit composed of, for example, a microcomputer, and the main control unit is described below based on a built-in control program. Control the.

(2) is an input unit, which is a specific key in addition to a character key (not shown) for inputting characters, symbols, etc., a cursor key (not shown) for instructing cursor movement, (3) is provided. (4) is a text memory in which documents are stored line by line. (5) is a one-line buffer, and the buffer can store one line of the document in the text memory (4). (6) is a display unit including a CRT or LCD, and (7) is a cursor position storage unit, and the storage unit stores information indicating the display position of the cursor displayed on the display unit (6). .. Reference numeral (8) is a display control unit, which displays the document in the text memory (4) output from the main control unit (1) on the display unit (6) and also at the cursor position storage unit (7). A cursor is displayed on the display unit (6) based on the position information inside.

FIG. 2 is a flow chart showing the control operation of the main control unit (1) based on the above control program, and the operation of this embodiment will be described below based on this chart.

First, when the power is turned on and an instruction to display a document in the text memory (4) on the display unit (6) is given from the input unit or the like, the main control unit (1) causes the text memory (4) to be displayed. The document is read from this and displayed on the display unit (6) through the display control unit (8) as illustrated in FIG. The diamonds at the left and right ends in FIG. 3 are left and right margin marks that define the number of characters in one line, and the dot “•” indicates a space. At this time, the main control unit (1) stores information indicating this position in the cursor position storage unit (7) so that the position of the first character of the document displayed on the display unit (6) becomes the display position of the cursor. .. As a result, the cursor (10) is displayed at the position of the first character "A" of the document displayed on the display unit (6) as shown in FIG.

After that, the main control unit (1) waits for an input from the input unit (2) in step S2, and if there is an input, it is determined whether or not the key input in the subsequent step S3 is the specific key (3). To judge. If it is determined in this determination that the key is not the specific key (3), the process proceeds to step S4.

In step S4, it is determined that the key input from the input unit (2) is a character key or cursor key, and conventionally known document input processing or cursor movement processing is performed, and the processing is returned to step S2.

On the other hand, if it is determined that the key is the specific key (3) in step S3, the process proceeds to step S5.

In step S5, based on the position information in the cursor position storage unit (7), one line of data in the document where the cursor (10) is currently located is read from the text memory (4) and the one line buffer (5) is read. ). Specifically, in the state shown in FIG. 3, the character string “A BC ... D ...” That includes the space for one line displayed on the first line of the display unit (6) is stored in the one-line buffer. It is stored in (5).

In the subsequent step S6, the character string stored in the one-line buffer (5) is searched for a character other than a space and located at the rightmost end. Specifically, it is performed by determining whether or not there is a space for each character from the right end of the character string in the one-line buffer (5). Now, assuming that the data of the first line on the display unit (6) of FIG. 3 is stored in the one-line buffer (5), the position of the character "D" is determined to be the rightmost position of the character.

After that, the process proceeds to step S7, in which the position information in the cursor position storage section (7) is changed based on the rightmost end position of the character searched in step S6. Specifically, when the character “D” position in FIG. 3 is determined to be the rightmost position of the character in step S6, the position on the right side of the character “D” position on the display unit (6) is displayed. The information is stored in the cursor position storage unit (7) as new cursor display position information. As a result, the cursor (10) is moved to the right of the character "D" as shown in FIG. When the process of step S7 ends, the process returns to step S2.
