Abstract

PURPOSE:To omit the troublesome resetting the cursor repeating interval value by storing the cursor repeating interval value of each operator into a memory which can hold this interval value even at the break of a power supply and then setting automatically the cursor repeating speed at the cursor repeating interval value that is previously set based on an input operator identifier. CONSTITUTION:A control part 12 includes a repeating interval table which stores the information on plural operators via a battery back-up memory BUM 24 which stores an operator identifier and its key repeating input interval even at the break of a power supply. Then the BUM 24 is searched with the input operator identifier used as a key, and the key repeating input interval value set previously by the operator is searched. Thus the key repeating input interval value is automatically set in correspondence with the operator. Therefore it is not required to set again the key repeating input interval value in case plural operators work in turn.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a key input control method for a keyboard/display device, and more particularly to a key input control method for automatically setting a key repeat input speed.

(Prior Art) Conventionally, the key input speed of a display device is set to only one stored key repeat input interval value. Furthermore, if the operator wishes to change the key repeat input speed, he or she must directly reset the key repeat input interval value by typing on the keyboard.

(Problem to be Solved by the Invention) The conventional key input control method described above stores only one type of key repeat input interval value, so multiple operators who use different key repeat input interval values have to take turns. When working with , the key repeat input interval value had to be reset each time.

(Means for Solving the Problems) The key input control method of the keyboard display device according to the present invention retains the key repeat input interval value determined for each operator in the storage means even when the power is turned off, and stores the key repeat input interval value input by the operator. A key repeat input interval value corresponding to the operator identifier is read from the storage means, and a key repeat input speed is set to the read key repeat input interval value.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a system configuration diagram showing an embodiment of the present invention, which includes a CRT display 11, a control section 12 of a terminal device,
A keyboard input device 13 is provided, and by continuing to press the same key on the input device 13, data corresponding to that key is repeatedly input and repeatedly displayed on the CRT display 11.

When the operator types an operator identifier via the keyboard input device 13, the key repeat input interval value corresponding to the operator is automatically selected from among the key repeat input interval values for each operator stored in the control unit 12. is set to

FIG. 2 shows a functional block diagram of this embodiment.
The control unit 12 includes a repeat interval table in a battery backed memory (abbreviated as BUM) that stores the operator identifier and its key repeat input interval value even when the power is cut off. This table stores information about multiple operators.

The operation of this embodiment will be explained with reference to the operation flowchart of this embodiment shown in FIG.

In FIG. 3-1, an operator sits in front of a terminal and first inputs an operator identifier before starting work. This is a flowchart for searching the BUM 24 using this identifier as a key, finding the key repeat input interval value previously set by the operator in FIG. 3-2, and setting it in the OS area. FIG. 3-1 is a flow executed every time a work operator is replaced.

Figure 3-2 shows the flow that is executed when the operator wants to change the key repeat input interval at any time.The key repeat input interval can be adjusted by the operator pressing "A alignment" on the keyboard. This is done by

FIG. 3-3 describes the key repeat control flow of the keyboard control module.

First, data input by keystrokes on the keyboard is stored in the FIFO buffer of the O8, but when the same key is pressed, the same key does not enter the FIFO consecutively; The repeat flag is ON, and there is no data in the FIFO buffer.
The moment you stop pressing the key, the repeat graph turns OFF. Therefore, if there is data in the FIFO, normal input processing is performed instead of repeat processing, but if there is no data in the FIFO, the repeat flag 0N10FF is checked.
If it is ON, read the repeat input interval value set in the OS area in Figure 3-1, wait for that time, and then perform input processing.

FIG. 4 shows the hardware configuration of the apparatus of the above embodiment.

(Effects of the Invention) As explained above, the present invention stores the cursor repeat interval value for each operator in a storage device that can be retained even when the power is turned off, and the cursor repeat speed is preset according to the operator identifier input from the keyboard. The operator's cursor repeat interval value is automatically set to that operator's cursor repeat interval value, so the operator can automatically change the operator's own cursor repeat interval by simply entering the operator identifier (usually entered by the operator on a terminal). The repeat speed is set, eliminating the hassle of resetting the cursor repeat interval value.
