Abstract

PURPOSE:To move a cursor for a long distance in a short time by providing software which increases the moving speed of the cursor at the time of continuously depressing a cursor key for a prescribed time or longer. CONSTITUTION:Application software 8 judges whether a key inputted on a keyboard 4 is an effective key adapted to the work or not. If it is an effective key, prescribed processing is performed; but otherwise, the key input is requested again. When the input key is a cursor moving key and is continuously depressed for a prescribed time or longer, the cursor moving speed is increased. Thus, the cursor 3 is moved in a short time though it is moved for a long distance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cursor movement control device for controlling cursor movement during data input in a word processor or the like.

[Conventional technology]

Conventionally, in this type of cursor movement control device, when a cursor movement key is pressed continuously, the cursor is moved continuously at a constant speed, similar to when a key is pressed repeatedly. Ta.

[Problem to be solved by the invention]

In the conventional device described above, if the cursor movement key is pressed continuously, the cursor starts to move continuously after a certain period of time, but the cursor movement speed does not change at that time, so the cursor movement distance is If it is long, it will take the same amount of time as pressing a key repeatedly, and the disadvantage is that the cursor movement will gradually feel slower.

[Means to solve the problem]

According to the present invention, application software is provided in the controller to control the cursor movement speed to be increased when a cursor movement key is continuously pressed for a predetermined period of time or more.

[For production]

In the present invention, the application software in the controller increases the cursor movement speed when the cursor movement key is pressed for a predetermined period of time or more, so that the cursor can be moved over long distances in a short time.

〔Example〕

Next, embodiments 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 CBr 13 connected to the word processor 1 is a CB
cursor displayed on r4, 4 is a keyboard for inputting data etc. to word processor 1 (hereinafter referred to as "time"), 5 is CB
CRT control software that controls the display of r2, 6 is K
KB control software that controls H2, 7 is word processor 1
The timer software 8, which manages time within the KH2, determines whether the key input from the KH2 is a valid key suitable for work.If it is a valid key, it performs the specified process, and if it is not valid, it presses the key again. An application software that requires human power and controls the cursor movement speed to be increased if the input key is a cursor movement key (hereinafter referred to as a cursor key) and is pressed continuously for a predetermined period of time. Software (hereinafter referred to as AP software) 9 is core control software that efficiently executes the entire software described above.

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

In the figure, first, a request is made to the KB software 6 for key personnel suitable for the business (step AI).

At this time, the KB software 6 is started. Step A2) to determine whether the input key is a valid key or not;
If it is not valid, the process returns to step A1, and if it is valid, it is determined whether the key is a cursor key or not (step A3).
). If it is a cursor key, check whether the cursor key has been pressed continuously by checking whether the continuous flag is on or off (step A4). If the cursor key remains pressed (flag on), determine whether the internal counter is already counting. If counting is in progress, continue counting (Step A7); if not, reset the counter and start counting (Step A6).
). Then, a counter that counts the number of continuous presses of the cursor key is separately designated and compared with 9 hours TI (Step A8), and if the value of the counter is larger than Ti, the cursor is moved n at a time (Step A9). T
If i is smaller, just exit. Note that if the continuous flag is off in step A4, the cursor is moved by one position (step A10) and then the process ends.

FIG. 3 is a chart 70 showing the operation of the KB control software 6.

KB control software 6 is the main routine (Figure (a))
and an interrupt routine (Figure (b)).

(a) The main routine shown in the figure is started by O8 of the system (not shown) (step Kl). The causes of its activation are: 1) activation from an interrupt routine (Figure (b)) activated by pressing or leaving a key; 2)
Activation from the command in step A1 of the AP software 8, 3) activation due to timeout, and the processing contents are separated depending on the cause (2' in step).

Note that the timeout in step 3) is performed in step C of Fig. 4(b).
This occurs when a certain period of time has elapsed after the process ended with the timer activated in step 1. Also, (a) ■, ■ in the figure
, ■ correspond to the activation types 1) to 3) described above, respectively. (b) The interrupt routine shown in the figure is activated by key input from KH2 (step 3). First, read the code of the input key (step C2), then step to determine whether it is a make signal (signal that occurs when the key is pressed down) or a break signal (signal that occurs when the key is released) Step 5), if it is a break signal, set that code in the FIFO memory (Step 6), then start the main routine (Figure (a)) (Step 7).
). Note that if there is a break signal at step 5, the process also moves to step 7.

FIGS. 4(a) to 4(C) correspond to each process after the steps 2 to 3 are divided into steps 2 to 3 in FIG. 3(,).

(a) The figure shows startup from an interrupt routine, Figure 3) shows startup by a command from the AP software 8, and Figure (C) shows processing in the case of startup due to timeout.

In the figure (a), it is first determined whether or not an arbitrary command is being executed (step W1), and if so, the timer is reset once (step W2), and the timer is activated again (step W3). After that, the type of interrupt is determined (step w4), and if it is a break signal, the process ends, and if it is a make signal, the process moves to step W5.
i. Read the code set in the FIFO memory and determine whether the code is a function code (hereinafter referred to as F code) corresponding to a predetermined function key on the KBJ or a data code other than the F code (step W
6). If it is data, store it in the buffer, step W7.
), it is determined whether the data has the specified length or not (Step W8)
), if it is smaller than the specified length specified by the AP software 8, the process ends, and if it is greater than or equal to the specified length, the process moves to step W9. If the F code is determined in step W6, the process also moves to step W6, and the F code or data code is
When handed over to software 8 and reset the timer (
Stella 7'W1G), command ends step W1
1) Finish these processes.

(b) In the figure, first start the timer (Step C1)
, read the code from FIFO memory (Stella 7”C2
), to determine whether there is a data code, step C3), and if there is a data code, proceed to step W6 in the figure (a),
If there is no data, the process ends.

(C) In the figure, it is determined whether the command is being executed or not (step T1), if it is being executed, it is determined whether the command is waiting for a break signal or not (step T2), and if it is waiting for a break signal, the counter is incremented (step T3). ), it is determined whether the counter is greater than an arbitrary time t (step T4). This time t is a value determined by the system or the operator, and is a specified value that determines how long the key must be held down for the cursor to move continuously in the AP software 8. This value is too small. As soon as you press the cursor key, the cursor movement will increase. If the time is greater than the time t, the continuation flag of the counter is turned on and step T5) is completed. Note that if the command is not being executed in step T1 or if the break signal is not being waited for in step T2, the process moves to step T6, the counter is set to O, and the continuous flag of the counter is turned off (step T7).
and exit. If the counter value is smaller than time t in step T4, the continuous flag is also turned off and the process ends.

As described above, according to this embodiment, the AP software 8 detects that the cursor key has been pressed continuously, and makes sure to increase the amount of movement of the cursor per unit time after a predetermined time has elapsed. Therefore, even when moving the cursor over a long distance, it can be done in a short time.

〔Effect of the invention〕

As described above, according to the present invention, software is provided that increases the moving speed of the cursor when the cursor key is pressed continuously for more than a predetermined time, so that even when the cursor is moved over a long distance, the cursor can be moved in a short time. The effect is that it can be done with
