Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character display device with improved handling properties.

With the development of computer systems, character display devices are often used as one of the information input devices.
This character display device consists of a keyboard device equipped with character code keys, control code keys, etc., and a display device that sequentially displays the character pattern indicated by the input character code at the display position indicated by the cursor. be done.

In the display device, each time a character code is input and the character pattern indicated by the character code is displayed at the cursor display position, the cursor display position is moved to the next character pattern display position and the next character is displayed. Prepare for code entry. This is repeated in sequence to input a series of character information consisting of a string of character codes.

By the way, when correcting a previously input character code, use the cursor movement control keys instead of the normal character code keys to move the cursor display position in the specified direction, and then move the cursor to the character pattern display position to be corrected. After matching, the character code to be corrected is entered. However, in the conventional device, after the above character code correction is completed, when returning to the original state and continuing character code input,
Since the cursor movement control key must be operated again to determine the cursor display position, the handling and operability are poor.

Also, even if you temporarily move forward from the current character code input position to input a character code, and then return to the original position and resume inputting the character code, you must operate the cursor movement control keys one by one. It was necessary to determine the cursor display position.

The present invention has been made in consideration of these circumstances, and its purpose is to provide a highly practical character display device that is easy to handle and allows operations such as correction of character codes to be performed easily. It is in.

The outline of the present invention is that when the cursor display position is moved by operating the cursor movement control key, such as when correcting a character code, if the previous input code was a character code, the input code at that time is By memorizing the cursor display position and moving the cursor back to the memorized cursor position by operating the cursor return key when the correction process is completed, the above purpose is effectively achieved by improving the usability. This is what I did.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of the present invention, and FIG. 2 is a diagram showing an example of a display format.

The input unit 1 includes, for example, a keyboard input device, and includes a plurality of character code keys, various control code keys, and the like. The character code keys and control code keys input through the input section 1 are input to the code identification section 2, where each is identified. Thus, the character codes identified by the identification section 2 are sequentially stored and stored in the storage section 3. Further, each time the character code is input, the cursor position control section 4 sequentially moves a cursor position to be displayed on a display screen, which will be described later, to designate the position. The cursor position control section 4 also issues a control signal to move the cursor in the designated direction in accordance with a code input by operating a cursor movement control key. In this way, the display position information specified by the cursor position control section 4 is stored in the storage section 3 in correspondence with the character code.

The character code and its display position information stored in the storage section 3 are supplied via the cursor position storage section 5 to a display section 6 consisting of a CRT display or the like, and are displayed, for example, as shown in FIG.
Further, the display section 6 is configured to move the cursor display position each time a character code is input in accordance with the cursor position movement information given from the cursor position control section 4 in order to prepare for the next character code input.

In Figure 2, the characters A, B, C and ○ marks represent the character pattern indicated by the input character code, and the horizontal line marks indicates a cursor mark. This cursor mark specifies the character pattern display position of the character code to be input next.

Incidentally, the cursor position storage section 5 stores the coordinates of the cursor display position when the cursor movement is started by the cursor position movement control key. This memorized cursor coordinate is
This information is read out when the cursor return key is operated from the input unit 1, and is used as control information to move the cursor to the position indicated by these coordinates.

Therefore, when inputting character information by sequentially inputting character codes by operating the character code key, for example, when correcting a previously input character code, the cursor position movement control is used instead of inputting the character code. Operate the keys to move the cursor to the character pattern display position to be corrected. At this time,
Since the previous input code was a character code, the cursor position at the start of cursor movement is stored. After correcting the character code, the user operates the cursor return key and inputs the information, thereby immediately returning the cursor to the original character code input position.

FIG. 3 is a diagram showing an example of the control flow. First, it is determined whether the input code is a character code, a cursor movement code, or a cursor return code. Thereafter, if the code is a cursor movement code, it is determined whether the code input immediately before is a character code or not, and the cursor position is registered and stored. Then, when the cursor return key is operated after the desired character code has been corrected, it is detected, the previously registered cursor position information is read out, and the cursor is moved according to that information. Just configure the control flow.

According to the device configured in this way, after the character code is corrected, the cursor display position can be immediately returned to the original position by operating the cursor return key, and character code input operations can be performed extremely quickly. can. In other words, it is not necessary to operate the cursor movement control keys each time when returning the cursor, and a so-called one-action operation can be performed, which has a great practical advantage. Furthermore, the purpose can be effectively achieved through simple control such as storing the cursor position.

Note that the present invention is not limited to the above embodiments. For example, character code correction targets may be specified for a plurality of consecutive display positions. Further, a plurality of cursor positions may be stored. Further, as character codes, kana, kanji, alphabetic characters, numbers, etc. can be targeted. In short, the present invention can be implemented with various modifications without departing from the gist thereof.
