Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to data input in a word processor, etc.
The present invention relates to a cursor movement control device that controls cursor movement.

[Prior Art] Conventionally, in this type of cursor movement control device, when the cursor movement key is continuously pressed, the cursor is continuously pressed at a constant speed as in the case of continuous tapping of the key. Was moving.

[Problems to be Solved by the Invention]

In the conventional device described above, when the cursor movement key is continuously pressed, the cursor starts to move continuously after a certain period of time, but since the cursor movement speed does not change at that time, the cursor movement distance is If it is long, it takes the same amount of time as when keys are repeatedly hit, and there is a drawback that the cursor movement feels gradually slower.

[Means for Solving the Problems]

The present invention starts counting at the time when it is detected that the cursor movement key is continuously pressed down for a predetermined time, and when the count value becomes larger than a preset time, the cursor movement per unit time is moved. It is designed to increase the amount.

[Work]

According to the present invention, when the cursor moving key is pressed for a predetermined time or longer, the moving speed of the cursor is increased, so that the cursor can be moved over a long distance in a short time.

〔Example〕

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

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

In the figure, 1 is a word processor (hereinafter referred to as a word processor), 2 is a CRT connected to the word processor 1, 3 is a cursor displayed on the CRT 2, and 4 is a keyboard for inputting data etc. to the word processor 1 (hereinafter, 5) CRT control software for controlling the display of CRT2, 6 for controlling KB4
Control software, 7 is timer software that manages time in the word processor 1, 8 is whether the key input from KB4 is a valid key adapted to the work, and if it is a valid key, a predetermined process is performed. If it is not valid, key input is requested again, and if the input key is a cursor movement key (hereinafter referred to as the cursor key), the cursor movement speed is increased if it is continuously pressed for a predetermined time. Application software (hereinafter,
AP software), 9 is core control software that efficiently executes the above software.

Next, the operation of the AP software 8 will be described with reference to FIG.

In the figure, first, the KB software 6 is requested to input a key adapted to the task (step A1). At this time, the KB software 6 is activated. It judges whether the entered key is a valid key (step A2).
If it is valid, the process returns to A1 and it is determined whether or not the key is the cursor key (step A3). If it is the cursor key, it is judged whether the cursor key is continuously pressed or not by turning on / off the continuous flag (step A4). If it is pressed (flag on), it is already counted by the internal counter. It is judged (step A5), if the counting is in progress, the counting is continued (step A7), if it is not counted, the counter is reset and the counting is started (step A6). Then, the counter that counts the continuous pressing of the cursor key is compared with the separately designated time Ti (step A8), and if the counter value is larger than Ti, the cursor is moved n times at a time (step A9). If it is smaller than Ti, it ends. If the continuous flag is off at step A4, move the cursor by one (step A1
0) and then finish.

FIG. 3 is a flow chart showing the operation of the KB control software 6.

The KB control software 6 is composed of a main routine (Fig. (A)) and an interrupt routine (Fig. (B)).

The main routine shown in (a) is a system (not shown).
It is started by the OS (step K1). The causes of the activation are 1) activation from an interrupt routine (Fig. (B)) activated by pressing the key and its release, 2) activation from the AP software 8 step A1 command, and 3) activation by a timeout. However, the processing content is divided according to the cause (step K2). It should be noted that the timeout 3) means that the processing is completed in a state where the timer is started in step C1 of FIG.
Further, in FIG. 5A ,, and correspond to the types of startup described in 1) to 3). The interrupt routine shown in (b) is activated by key input from KB4 (step K
3). First read the code of the entered key (step C
2) Next, determine whether it is a make signal (a signal generated when the key is pressed) or a break signal (a signal generated when the key is released) (step K5), and if it is a break signal, the code To the FIFO memory (step K
6) Then, the main routine ((a) figure) is started (step K7). If a break signal is output at step K5, the process proceeds to step K7.

FIGS. 4 (a) to 4 (c) correspond to the respective processes after being divided by to in step K2 of FIG. 3 (a).

FIG. 7A shows the processing from the interrupt routine, FIG. 8B shows the processing by the command of the AP software 8, and FIG.

In the figure (a), first, it is judged whether or not an arbitrary command is being executed (step W1), and if it is being executed, the timer is once reset (step W2) and the timer is started again (step W3). After that, the type of interrupt is judged (step W4), if it is a break signal, it ends as it is, and if it is a make signal, it moves to step W5 and the code set in the FIFO memory is read. It is determined whether it is a function code (hereinafter referred to as an F code) corresponding to a predetermined function key or a data code other than the F code (step W6). If it is data, it is stored in the buffer (step W7), it is judged whether or not the data has the specified length (step W8), and if it is smaller than the specified length specified by the AP software 8, the process ends, and if it is the specified length or more. If so, move to step W9. Even if it is determined to be an F code in step W6, the process moves to step W6, the F code or data code is passed to the AP software 8, and the timer is reset (step W10), and the command ends (step W1).
1) End these processes.

In the figure (b), first, start the timer (step C1),
The code is read from the FIFO memory (step C2), the presence / absence of a data code is determined (step C3), and if there is a data code, the process proceeds to step W6 in (a), and if there is no data, the process ends.

In the figure (c), it is judged whether or not a command is being executed (step T1), and if it is being executed, it is judged whether or not it is waiting for a break signal (step T2). If it is waiting for a break signal, the counter is incremented. (Step T3), it is judged whether or not the counter is longer than an arbitrary time t (Step T4).
This time t is a value determined by the system or the operator,
If you keep pressing the key for a while, AP software 8
Is a specified value indicating whether the cursor moves continuously. If this value is too small, the amount of movement of the cursor increases immediately when the cursor key is pressed. If it is longer than the time t, the continuation flag of the counter is turned on (step T5), and the process ends. If the command is not being executed at step T1 or the break signal is not waiting at step T2, step
The process proceeds to T6, the counter is set to 0, the continuous flag of the counter is turned off (step T7), and the process is ended. If the counter is smaller than the time t at step T4, the continuous flag is turned off and the process is ended.

As described above, according to the present embodiment, the AP software 8 detects that the cursor key is continuously pressed,
Since the amount of movement of the cursor per unit time is increased after the lapse of a predetermined time or more, it is possible to move the cursor for a long distance in a short time.

〔The invention's effect〕

As described above, according to the present invention, when the cursor key is continuously pressed for a predetermined time or more, the moving speed of the cursor is increased, so that the cursor can be moved in a short distance in a short time. effective.
