Abstract

PURPOSE:To shorten a key repeat interval according to time for pushing keys down and to enable high-speed input by providing a timer to measure the time for pushing keys down and a means to change a key code generating interval according to the value of the timer. CONSTITUTION:A timer 3 starts measuring the time after the keys of a keyboard 4 are pushed down, and the timer is reset when the keys are returned. A key generation circuit 2 reports the codes of the pushed-down keys on the keyboard 4 to a data processor control part 1. For example, when a key A is continuously pushed down by a user, the timer 3 measures this time and first of all, the key generation circuit 2 reports the key code A to the data processor control part 1. Afterwards, the value of the timer 3 is monitored and for example, when the value of the timer 3 is smaller than 3 seconds, the code is informed of the data processor control part 1 at every 0.5 second. When the value is smaller than 5 seconds after the lapse of 3 seconds, the code is informed at every 0.4 second, when the value is smaller than 10 seconds after the lapse of 5 seconds, the code is informed at every 0.3 second and when the value is larger than 10 seconds, the code is informed at every 0.2 second.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard control system for an information processing apparatus, and more particularly to key repeat interval control.

[0002]

2. Description of the Related Art The conventional key repeat interval time control of an information processing apparatus has been controlled by a time fixed in advance by a system or a user.

[0003]

The above-described conventional key repeat interval control has a disadvantage that it takes time to generate a large amount of the same character code because the character code is generated at a preset time. Especially when the cursor is moved, it often takes time to keep pressing the same key.

[0004]

SUMMARY OF THE INVENTION A keyboard control system of the present invention comprises a timer for measuring the time during which a key is pressed and a timer for measuring the time during which the key is generated when the user keeps pressing the key. And a means for changing the key code generation interval according to the value.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The keyboard 4 is a device for inputting data.
The timer 3 starts measuring time from when the key of the keyboard 4 is pressed and is reset when the key is returned.
The key generation circuit 2 notifies the data processor control unit 1 of the code of the key pressed by the keyboard 4.

Next, the operation will be described.

When the user keeps pressing the key "A", for example, the timer 3 measures the time during which the user keeps pressing it. The key generation circuit 2 first notifies the data processing device control unit 1 of the key code of'A '. After that, the value of timer 3 is monitored, and when the value of timer 3 is 3 seconds or less, every 0.5 seconds. When the value exceeds 3 seconds, but less than 5 seconds, every 0.4 seconds. In this case, the data processing apparatus control unit 1 is notified of the key code of'A 'every 0.3 seconds, and every 0.2 seconds in the case of 10 seconds or more.

The relationship between the value of the timer 3 and the key code generation interval described above is an example, and the key code generation interval can be changed by changing the function.

[0010]

As described above, according to the present invention, when a large number of the same characters are input by changing (shortening) the key repeat interval depending on the key pressing time, it is possible to input at high speed.
