Abstract

PURPOSE:To continuously input the same data without continuing the key input operation by continuously generating data held in a data holding means at a prescribed time pitch in the repeat mode. CONSTITUTION:The repeat mode is set in accordance with a prescribed key operation; and thereafter, when depression of a data input key is detected, data corresponding to this key is held in a data holding means (repeat buffer) 5. As long as the repeat mode is set, a data continuous generation means 6 continuously generates data held in the data holding means 5 at intervals of a prescribed time. Thus, the same data is continuously inputted by one key operation for setting of the repeat mode and one key operation for data input.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a keyboard device used as an input device for various information processing systems.

(Prior Art) When creating test data or the like on a computer by inputting data through a keyboard device, the same key data is often input continuously.

In such cases, conventional keyboard devices require the same key to be pressed repeatedly as many times as necessary, or devices with a repeat function require the user to continue pressing the same key.

In other words, even if the same key data is input, some key operations must be performed continuously.

(Problems to be Solved by the Invention) The present invention is intended to solve such problems, and it is an object of the present invention to provide a keyboard device that can input the same data continuously without performing key input operations continuously. The purpose is

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the keyboard device of the present invention has the following features:
a repeat mode setting means for setting a repeat mode in response to a predetermined key operation; a pig holding means for holding data corresponding to a key first pressed to input data after setting the repeat mode; The apparatus includes continuous data generation means that continuously generates the data held in the data holding means at a predetermined time pitch while the data is set.

(Function) In the keyboard device of the present invention, the repeat mode is set in response to a predetermined key operation, and after that, when the press of the data key is detected, the data corresponding to the key is stored in the data holding means. is maintained.

Thereafter, the continuous data generating means continuously generates the data held in the data holding means at predetermined time intervals while the repeat mode is set.

Therefore, according to the keyboard device of the present invention, the same data can be input continuously by performing key operations for setting the repeat mode and key operations for data input one time each.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing the disadvantages of a keyboard device according to an embodiment of the present invention.

In the figure, ] is a group of key switches arranged in a 7-trick pattern corresponding to each key, and 2 is a key switch group 1 of this key switch group.
In the figure, a plurality of X-direction key press position detection lines are used to detect key press positions in the X-direction key arrangement, and 3 indicates a plurality of Y-direction key press position detection lines for detecting key press positions in the Y-direction key arrangement in the figure. This is the key 1111 lower position detection line. Further, 4 is a decoder for sending a scan signal to each of the Y-direction key press position detection lines 3 (2) and 17 (17).

In addition, 5 is a repeat buffer (RAM) in which key data to be generated continuously is held when this keyboard device is set to the repeat mode described later, and 6 is a controller that controls each of the following +M sections. It is a CPU.

In this keyboard device, a function for setting and canceling the repeat mode is assigned to a specific key (key switch).

Next, we will explain the operations typical of this keyboard device.
This will be explained with reference to the flowchart shown in the figure. Furthermore, the first
The figure shows the flow of the repeat control routine.

First, the operator presses down the key for setting the repeat mode (step A), so that the repeat mode is set on this keyboard device (
Step B).

After this, when the operator presses a certain key to input data (step C), that key is set in the repeat buffer 5 (step D), and at the same time a timer indicating the repeat interval time is activated (step E).
.

Thereafter, a timer interrupt is generated every time the timer's repeat interval has elapsed (step F), and key data is read from the repeat buffer 5 each time (step G).

The data is then input to the main body of the information processing device.

Thereafter, when the operator presses a key for canceling the repeat mode (step H), the timer is stopped (step 2), the repeat buffer 5 is cleared, and the repeat mode is canceled (step J).

Thus, according to the keyboard device of this embodiment, the same data can be input continuously by performing key operations for setting the repeat mode and key operations for data input one time each. Therefore, it is possible to improve the operability especially when inputting data such as creating test data, in which the same key data is frequently input in large numbers in succession.

[Effects of the Invention] As explained above, according to the keyboard device of the present invention,
The same data can be input continuously by simply turning the keys to set the repeat mode and the keys to input data.
