Abstract

PURPOSE:To easily performs the insertion, correction, etc., of a character, a symbol, etc., at a position where the attribute of the character or symbol change. CONSTITUTION:This input controller is equipped with a cursor C1 which indicates a character or symbol input position, a position changing means which changes the position of the cursor C1, and a control means which changes the attribute of the inputted character or symbol to the attribute at a position (c) before movement when the cursor C1 moves to the character or symbol attribute change position (d) from the position (c) right before it in response to the input of the position changing means and also changes the attribute of the input character or symbol to the attribute (f) at the position of the attribute change when an input for movement in an input order direction is sent from the position changing means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be easily implemented in a document processing apparatus or the like having attributes associated with input of various typefaces, character sizes, modification information, etc., depending on the position of input position indicating means such as a cursor. The present invention relates to an input control device that controls these attributes.

[0002]

2. Description of the Related Art Conventionally, it is known that electronic devices such as word processors and personal computers have various attributes such as a typeface, character size, and decoration information related to input when performing document processing. These are input and used by the input means, respectively, but these attributes are mixed to create a document. For this reason, these attributes are different in mixed documents, so you can modify (insert /
When deleting), the operation is often complicated. Therefore,
When the cursor for input position indication is moved to enter the attribute, it is generally controlled to switch to those attributes.

[0003]

However, in the above-mentioned conventional example, when the input position designating means such as a cursor goes up to enter the previous attribute, and when it is in those attributes, the attribute remains as it is. It is possible to use it, but at the position where the attribute changes, in order to switch to the next attribute and insert characters / symbols etc. at this position, attributes such as typeface / character size / decoration information should be added again. It had the drawback of having to switch.

Therefore, an object of the present invention is to provide an input control device which solves the above problems.

[0005]

In order to achieve the above object, the present invention provides an input position indicating means for indicating an input position of a character / symbol, a position changing means for changing the position of the input position indicating means, and the position changing. When the input position designating means moves from one position before the attribute change position of the input character / symbol to the attribute change position by the input of the means, the attribute of the input character / symbol is changed to the attribute of the position before the movement. Further, when there is an input in the input order direction by the position changing means, it further comprises control means for changing the attribute of the input character / symbol to the attribute of the attribute changing position.

[0006]

According to the present invention, it is possible to easily insert / correct a character / symbol or the like at a position where the attribute changes without changing the attribute by a complicated instruction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings.

FIG. 1 is a block diagram showing the configuration of an electronic device to which the present invention is applied. In FIG. 1, reference numeral 1 is a keyboard as an input of an electronic device. There is a K1 font switching instruction key in this, and Corrie (Corrie)
r), Swiss (Swiss), Dutch (Dutch) and so on. K2 is a style switching instruction key for instructing bold, italic or underline. K3 is a size change key, 9 points, 12
Change the font size, such as point or 18 point.
K4 is a cursor forward key, and K5 is a cursor backward key for instructing the movement of the cursor described later. K6 is a key group of ordinary characters and symbols.

Reference numeral 2 denotes a control unit for controlling the input / output of this electronic device. This structure has a ROM and a work area in which a program for executing the control procedure as shown in FIG. It is composed of a RAM and peripheral circuits.

Reference numeral 3 denotes a display unit, which is under the control of the control unit 2 and has a dot-matrix display form for displaying characters and symbols in various fonts / styles / sizes designated by the keyboard 1. And the cursor is also displayed.

Next, FIG. 2 shows the transition of the display state of the display unit 3 under the control of the control unit 2. Here, (a) is a normal input state. C1 is a cursor, the shape of which changes depending on the character size. Now suppose the operator finds a misspelling in this sentence. It is "the" instead of "th". Therefore, the operator uses the key K5 to move the cursor C1 back. At this time, the position (b) is the position where the operator has switched by the K1, K2, and K3 keys when inputting characters / symbols. At this position, the cursor C1 is shown in the mode after switching. Next, when the cursor C1 is moved to the position (c), the cursor C
1 is shown in the mode before switching. After that, even if the cursor C1 is moved in the forward direction by one character by the key K4 as shown in (d), the mode is not changed regardless of the mode switching position, and the character "e" is input here. ,
The character "e" is inserted as shown in (e), where
Even if the cursor C1 is moved in the forward direction by one character with the key K4, the position of the cursor C1 does not change and only the mode is switched (f).

[Other Embodiments] Next, other embodiments of the present invention will be described.

FIG. 3 is a block diagram showing the configuration of an electronic device to which the present invention is applied. In FIG. 3, 11 is a keyboard input unit. There is a K11 font switching instruction key for switching fonts. K12 is a style switching instruction key for changing the decoration information. K13 is a size switching instruction key that allows the size to be changed.

K14 is L / L (line / line mode)
It is a mode instruction key that is used to instruct the operation mode of the printing section described later, and the characters / symbols etc. entered by inputting this key are displayed by the print start instruction key (not shown here). It is printed. K15 is a cursor forward key, and K16 is a cursor backward key. K17 is a key group of ordinary characters and symbols.

Reference numeral 12 denotes a control unit for controlling the input / output of the electronic device, which has the same structure as 2 in FIG. 1 and executes the control procedure as shown in FIG. A display unit 13 has a dot-matrix configuration as in the previous embodiment. Further, a dot printer of a thermal head is connected as the printing unit 14. This printer is equipped with a thermal head for printing.

Next, FIG. 4 shows the transition of the display states of the 13 display parts. At this time, in order to instruct the L / L mode, the thermal head unit for performing printing of the printing unit 14 moves in the same manner as the cursor, and instructs the operator the printing position on the paper. As a result, as described in the above embodiment, the thermal head unit also moves by the same number of characters as the cursor on the display. (A) to (f) of FIG. 4 correspond to (a) to (f) of FIG.
The present embodiment is different from the above-described embodiment in that the thermal head unit moves in accordance with the movement of the cursor C1, and is otherwise similar to the above-described embodiment.

[0017]

As described above, according to the present invention, the input position designating means such as a cursor in a document processing apparatus having various types of fonts, character sizes, modification information and other attributes associated with input. These attributes can be easily controlled only by the position changing operation of.
