Abstract

PURPOSE:To continuously input data by a right key input without correcting the data by a wrong key input. CONSTITUTION:The push down time of a key when the key is pushed down is measured by a timer 3. When the push down time of the key is smaller than the preliminarily set value of a monitoring time memory 4, a key code is not generated. When it is larger, the key code corresponding to the pushed down key is generated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard device used in an information processing device, and more particularly to a key input system.

[0002]

2. Description of the Related Art Conventionally, in a keyboard device of this type, when a key is pressed, a key code corresponding to the pressed key is generated regardless of whether the key operation is correct or incorrect. Was becoming.

[0003]

By the way, the information processing apparatus has become widespread in general, and it has come to be used not only by physically healthy people but also by people with handicap.

For people with handicap, especially those who carry out key input with a stick for operating the key in their mouth, key input by the conventional keyboard device is very difficult and difficult to handle, and a dedicated keyboard is used. Development of the device was desired.

An object of the present invention is to provide a keyboard device which can be easily handled by a handicapped person.

[0006]

In order to achieve the above object, a keyboard device according to the present invention is a keyboard device of an information processing device for generating a key code by hitting a key, the key pressed by a user. A timer that measures the pressing time of the key, a monitoring time memory that stores a set time that serves as a reference for monitoring the key pressing time, a key pressing time measured by the timer, and a setting time stored in the monitoring time memory And means for outputting the key code corresponding to the pressed key only when the pressed time of the key exceeds the set time.

Further, the monitoring time memory has a monitoring time change key for the user to change the set time to be stored.

Further, it has a monitor time display panel for displaying the set time stored in the monitor time memory.

[0009]

In the present invention, the key press time is measured by the timer,
If the key press time measured by the timer does not reach the set time, the key operation is stopped as an error in the key operation.On the other hand, if the time exceeds the set time, it is determined that the key operation was performed correctly. The key code corresponding to the operated key is generated.

[0010]

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

FIG. 1 is a schematic block diagram showing an embodiment of the present invention.

In FIG. 1, an information processing device control section 1 performs data processing of the information processing device, and processes data from the keyboard 2.

The keyboard 2 generates a key code corresponding to the pressed key when the key is pressed, and the characters generated when the key is pressed are written on each key.

When a key of the keyboard 2 is pressed, the timer 3 measures the pressing time of the pressed key.

The monitoring time memory 4 stores the key pressing monitoring time set for comparison with the key pressing time measured by the timer 3, and the key pressing monitoring time is the monitoring time changing key 5 and It is changed and set by the monitoring time change key 6.

The monitoring time change keys 5 and 6 are keys for the user to set the key press monitoring time. On the other hand, the monitoring time change key 5 increases the number of key press monitoring times each time it is pressed. On the other hand, the other monitoring time change key 6 decreases the number of key pressing monitoring times, which is the opposite of the one monitoring time change key 5.

The monitoring time display panel 7 displays on the screen the contents of the key pressing monitoring time which is changed and set by the two monitoring time changing keys 5 and 6 and stored in the monitoring time memory 4.

Further, the keyboard 2 compares the key pressing time measured by the timer 3 with the key pressing monitoring time stored in the monitoring time memory 4, and compares the key pressing time with the set key pressing monitoring time. If it does not reach, the key code generation is stopped as an error in the key operation, and if the set key press monitoring time is exceeded, it is determined that the key was operated correctly and the operated key is It has a function of generating a corresponding key code. It also has a function of resetting the timer 3 after the key code is generated.

Next, the operation of the present invention will be described with reference to FIGS. First, the user presses the two monitoring time change keys 5 and 6 to set and register the key press monitoring time in the monitoring time memory 4.

That is, the user decides the time required for the correct key operation in consideration of the time required for the key operation by himself, and uses the two monitoring time change keys 5 and 6 as the comparison reference. The key press monitoring time is set and registered in the monitoring time memory 4.

The time set by the user is stored in the monitoring time memory 4 and displayed on the monitoring time display panel 7. The key press monitoring time can be changed at any timing.

When the user presses a key on the keyboard 2 after registering the setting of the key press monitoring time, the timer 3 is first activated and the press time of the pressed key is measured by the timer 3.

The keyboard 2 compares the value measured by the timer 3 with the key pressing monitoring time set in the monitoring time memory 4, and when the value measured by the timer 3 becomes larger, the key is pressed. It is determined that the key is the key to be input, and the key code corresponding to the pressed key is output to the information processing device control unit 1. After that, the keyboard 2 resets the timer 3 in preparation for the next key input.

On the other hand, when the value measured by the timer 3 is smaller than the content of the monitoring time memory 4, the keyboard 2 judges whether the pressed key is the key to be input or the wrong key. In order to do so, continue to monitor the pressed state of the pressed key, and if the key is no longer pressed after a certain period of time, identify the pressed key as being due to an erroneous operation, The timer 3 is reset in preparation for the next key input.

As described above, the keyboard 2 monitors the pressing time of the key pressed by the user, sequentially selects the key that the user wants to input, and outputs the key code corresponding to the key to the information processing device control unit. Enter 1.

[0026]

As described above, according to the present invention, the key code is generated when the user presses each key for more than the time set by the user. Even if the person who presses the key with a stick in his mouth) presses the key by mistake, if the pressing action is immediately stopped, the key code will not be generated and the user will not be required to modify the data. There is an effect that data that should be input can be input.
