Abstract

PURPOSE:To shorten the time of depression of keys on a keyboard by using a continuous input indicating key (DUP key) for key input to automatically generating the same key code a designated number of times continuously in a short time. CONSTITUTION:The key code inputted from a keyboard 1 is sent to a control circuit 4. The control circuit 4 discriminates whether the inputted key code includes the code from a DUP key 10 or not; and if it does not include the code of the key 10, the inputted key code is stored in a storage circuit 3 and is outputted to a higher information processor body. If it includes the code from the DUP key 10, the key code from the key 10 is converted to the number of times of continuous key code generation by the control circuit 4 and this number is set to a counter 2. The control circuit 4 counts down the set value of the counter 2 at each time of reading the key code from the storage circuit 3 until the set value of the counter 2 becomes zero. The key code read out from the storage circuit 3 is sent to the information processor body.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard input device, and particularly to a keyboard input device for repeatedly inputting a key code to an information processing device.

[Conventional technology]

Conventionally, this type of keyboard input device has been used to continuously press and hold a key whose key code you want to generate for a certain period of time, and then continuously generate the key code of the key that is being pressed at a certain period of time until the key is released. It is an auto-repeat that occurs.

[Problem that the invention seeks to solve]

The above-described conventional keyboard input device has a drawback in that the key must be kept pressed for a predetermined period of time or longer, since the key must be kept pressed while a key code is being generated. Another disadvantage is that when attempting to generate the same key code many times, the number of times the key code is generated must be counted by characters displayed on the screen, key click sounds, or key strokes.

[Means for solving problems]

The keyboard input device of the present invention has a continuous input instruction key that instructs continuous generation of key codes in combination with other keys, and a signal indicating the key code to be generated continuously, the number of occurrences of the key code, and continuous generation. a keyboard to enter
The device includes a count that sets the number of occurrences, a memory circuit that stores the key code, and a control circuit that reads the key code from the memory circuit until the set value of the counter becomes zero.

〔Example〕

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

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

In FIG. 1, 1 is a keyboard for inputting a key code, 2 is a counter for setting the number of repetitions input from the keyboard 1, 3 is a memory circuit for storing the key code, and 4 is a set value of counter 2 which is O. This is a control circuit that reads out the key code stored until the key code is reached and outputs the read key code to the higher-level information processing equipment.

FIG. 2 is a plan view of the keyboard of FIG. 1.

In Figure 2, 5 is a part of the fan cushion.

6 is a part of the first control key, 7 is a part of the ten key, 8 is a part of the full key, 9 is a part of the second control key, and 10 is a continuous input that instructs continuous generation of key codes in combination with other keys. This is an instruction key (hereinafter referred to as DUP key).

In FIG. 1, a key code input from a keyboard 1 is sent to a control circuit 4. The control circuit 4 determines whether or not the input key code includes the code from the DUP key 10. If the input key code does not include the code from the DUP key 10, the input key code is stored in the memory circuit 3. , is output to the upper information processing equipment main body.

When the DUP key 10 is pressed, the key code from the key pressed at the same time as or immediately after the pressing of the DUP key 10 is sent from the keyboard 1 to the control circuit 4. Control circuit 4
Then, the key code from the key pressed at the same time as or immediately after the DUP key 10 is converted into the number of consecutive key code occurrences and set in the counter 2. For example, when the "3" key is pressed, the control circuit 4 sets 3 times in the counter 2 as the number of consecutive occurrences.

The control circuit 4 subtracts 1 from the set value of the counter 2 every time the key code is read from the memory circuit 3, and repeats this until the set value of the counter 2 becomes 0. Sent to the main body.

〔Effect of the invention〕

As explained above, the present invention provides key human power for DUP
By using the keys, the same key code can be automatically and consecutively generated a specified number of times in a short period of time, which has the effect of reducing the time required to press the keys on the keyboard.

Furthermore, since there is no need to count the number of times a key code is generated using characters displayed on the screen, key click sounds, or key strokes, there is an effect that the input operation becomes easier.
