Abstract

PURPOSE:To efficiently continuously input a special character by inputting this character once and continuously depressing a repeat key to continuously input the same character. CONSTITUTION:A key data decision part 2 receives key data K generated in a keyboard input part 1 to decide its contents and performs various operations designated by a function key to generate and send a character code M and generates a repeat signal R at the time of depression of the repeat key on the keyboard input part 1. A repeat character storage part 3 receives only the character code M sent together with the repeat signal R and keeps the character code during continuation of the repeat signal R and continuously sends a repeat character code H for repeat of the character code M at intervals of a prescribed time. A character code output part 4 receives the character code M and the repeat character code H and outputs them to the external as an output signal O. Thus, the special character is continuously inputted efficiently.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a character input device.

[Conventional technology]

Conventional character input devices used in word processors, etc., can be used to input specific characters or symbols in succession.
By repeatedly pressing the key representing that particular character or symbol, the same character or symbol is input continuously.

For this reason, especially when you want to input special characters that do not have keys on the keyboard in succession, first indicate code input by pressing a specific function key that specifies code input, and then input You must enter one of the special characters by pressing the four digits of the desired code in the correct order) several times in succession.

[Problem that the invention seeks to solve]

With the conventional character input device described above, if you want to input a specific character or symbol in succession, you have to repeatedly press the key representing that specific character or symbol. In particular, if you want to input special characters in succession, It is necessary to repeat the operation of pressing a specific function key to specify code input and the four digits of the desired code many times in succession, and even if the same characters are input continuously, the user's input speed does not improve. There is a problem.

An object of the present invention is to provide a character system that allows the same character to be inputted in succession by inputting the character once and continuing to press the repeat key, and in particular allows continuous input of special characters to be performed efficiently. It is to provide an input device.

[Means for solving problems]

The character input device of the present invention includes: (A) a keyboard input unit that has character keys and various keys including a repetition key and a function key that can be operated in parallel with the character keys, and generates key data by pressing the keys; (B) Receives the key data generated by the keyboard input section, determines its content, and performs various operations specified by the function keys to form and send a character code, and in parallel, (C) a key data determination unit that generates a repetition signal when the key data indicates that a repeated key is pressed; (C) a key data determination unit that receives only the character code sent from the key data determination unit together with the repetition signal; as long as the repetition signal continues, and continuously sends out the character code at predetermined time intervals; The apparatus includes a character code output section that receives character codes sent from the storage section and outputs those character codes to the outside.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the character input device of the present invention.

In FIG. 1, a keyboard input unit 1 has various keys including character keys, repetition keys that can be operated in parallel with the character keys, and function keys, and key data K can be generated by pressing these keys. I can do it.

The key data determination unit 2 receives the key data K generated by the keyboard input unit 1, determines its content, and performs the initial action specified by the function key to form and send a character code M. In parallel with this, a repeat key is pressed on the keyboard input unit 1, and when key data K indicates that the repeat key is pressed, a repeat signal R is generated.

The repeated character storage unit 3 receives only the character code M sent from the key data determination unit 2 together with the repeated signal R, holds the character code M as long as the repeated signal R continues, and stores it for a predetermined period of time. A repeated character code H that repeats the character code M at intervals is continuously sent.

The character code output unit 4 receives the character code M sent from the key data determination unit 1 and the repeated character code H sent from the repeated character storage unit 3, and outputs these character codes to the outside as an output signal 0. .

Next, the operation when the user continuously inputs the special characters ◇ will be explained.

FIG. 2 is a screen information diagram showing an example of a screen displaying characters input by the character input device of this embodiment.

The output signal O of the character input device of this embodiment is generally the second
As shown in the figure, the data is sent to a CRT display device and displayed on the CRT screen. The ■ mark in FIG. 2 indicates the position of the cursor.

FIG. 2(a) shows initial screen information when the user starts inputting. In this state, the user presses the custom character input key, which is one of the function keys, and then presses the repeat key while pressing the four-digit code 2199, which indicates the custom character ◇.
Press .

As a result, as shown in FIG. 2(b), first, one external character ◇ is input and displayed.

If the user continues to press the repeat key without releasing it, the external characters ◇ are continuously input and displayed as shown in FIG. 2(c), and when the user releases the repeat key, the continuous input stops.

As described above, the character input device of this embodiment can easily input a large number of consecutive same characters by inputting the character once and continuously pressing the repeat key.

〔Effect of the invention〕

As explained above, the character input device of the present invention can easily input the same consecutive characters by inputting the character once and continuously pressing the repeat key.
In particular, continuous input of special characters can be performed efficiently.
This has the effect of improving the user's character input productivity.
