Abstract

PURPOSE:To quickly obtain the desired numerical value by securing a constitu tion where the change timing of the numerical value is gradually accelerated and at the increment of the numerical value is also gradually increased with the lapse of time from the push of a key. CONSTITUTION:A panel 4 includes the display devices 1a - 1c, the reduction keys 2a - 2c, and the increase keys 3a - 3c. Then a panel controller 5 and a processor 6 are added. In such a constitution, the addition/subtraction timing and the addition/subtraction value can be set optionally based on the repeated count value, i.e., the integration value of the interruption signals produced in the prescribed timing with operation of the keys 3a - 3c or 2a - 2c. Thus it is possible to set the change timing of an object to be displayed at a low speed at first and to gradually increase the timing speed and also to gradually increase the change width. As a result, the changing speed of the object to be displayed can be visually recognized and the desired object to be displayed can be quickly obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to, for example, a display device that displays numerical values, and particularly to display control thereof. [Prior Art] When increasing or decreasing a numerical value in a large range by pressing an increase key or a decrease key (hereinafter collectively referred to as an increase/decrease key), it takes time depending on the range, so conventionally, the increase/decrease key is used. Depending on how long the key is pressed down, the interrupt time corresponding to the processor is shortened and the number of times the processor changes the value is increased, or depending on how long the increase/decrease key is pressed down, the processor increases the amount of change in the value. was common. However, if the interrupt time interval is too short, the minimum interrupt time interval is determined by the processor used, so the interrupt signal may not be detected, or if there are multiple types of numerical values, each numerical value In order to change the rate of change according to the value, it is necessary to change the interrupt time according to the value to be changed, which complicates the control mechanism on the side that generates the interrupt signal. Furthermore, the processor increases the amount of change in the numerical value depending on the time the increase/decrease key is pressed, so the rate of change becomes faster, but since the timing of the change is constant, the speed of ε change from the operator's perspective is faster. The operator presses the increase/decrease key many times, and as a result, each time the increase/decrease key is pressed, the change returns to the minimum set value, so it takes a long time to reach the desired value. Sometimes it happened. Also, if you try to increase the rate of change of the numerical value by holding down the increase/decrease key to reach the desired numerical value quickly, and if you set a large change in the numerical value, you may not be able to achieve the desired value with just one change. There were times when the numbers exceeded the actual values. [Problems to be Solved by the Invention] In the conventional numerical display device as described above, the amount of change in the numerical value is set based on the time that the increase/decrease key is pressed, so although the speed of change is fast, Since the timing of the change is constant, the speed of change does not seem to be increasing, and you end up pressing the increase/decrease key many times, resulting in the change returning to the minimum set value each time you press the increase/decrease key. Therefore, there was a problem that it took a long time to reach the desired value. Furthermore, if the amount of change is set too large, there is a problem that even if the increase/decrease key is kept pressed, the desired value will be greatly exceeded in one change. This invention was made in order to solve this problem, and the speed at which the numerical value changes is not constant, but it changes in stages, and it is possible to reach the desired numerical value at a seemingly quick timing. The purpose is to obtain an indicator. [Means for Solving the Problems] A display device according to the present invention includes an increase key for instructing display of a displayed object corresponding to larger numerical data among displayed objects corresponding to numerical data, and an increase key for instructing display of a displayed object corresponding to larger numerical data; an input means having a decrease key for instructing the display of a display object corresponding to the data; and an interrupt signal generating means for continuously generating an interrupt signal at a predetermined timing based on the key operation of the manual means; Among the interrupt signals output from the interrupt signal generation means, there is a repeat counter that is reset by the first interrupt signal and accumulates subsequent interrupt signals, and a repeat counter whose count value and skip count value are constant. A skip table stored in a corresponding relationship, a step table in which count values of a repeat counter and step count values are stored in a certain relationship, and a corresponding skip count value of the skip table based on the count value of the repeat counter. is set, and a skip counter whose set value is subtracted each time an interrupt signal is generated, and when the value of the skip counter is 0, read the step count value of the step table according to the value of the repeat counter, Also, it corresponds to the calculation means that sets the skip count value of the skip table to the skip counter according to the value of the repeat counter, the addition or subtraction means that adds or subtracts according to the step count value read by the calculation means, and the value of the addition and subtraction means. and a display device that displays the displayed object. [Operation] In this invention, when the increase key or the decrease key of the input means is operated, the interrupt signal generating means generates an interrupt signal at a predetermined timing. Then, the repeat counter is reset by the first interrupt signal, and based on the value of this repeat counter, the skip count value of the skip table is selected and set in the skip counter. Further, the step count value of the step table is selected based on the value of the repeat counter. This step count value is added or subtracted in the addition/subtraction means according to the operation of the increase key or decrease key, and when the operation of the increase key or decrease key continues and the interrupt signal continues to be generated, the repeat counter is Accumulate and
The skip count value is subtracted every time the interrupt signal is input, and when the count value becomes 0, the above calculation is repeated according to the value of the repeat counter.

However, in this case, s (t) ＞5k(2) ＞・・・・・・＞
Let s k(&) be k. At first, the number of rejections is increased, and then it is gradually decreased. B (1) ~Bkc/-i> C. A boundary value (hereinafter referred to as "skip count value") which corresponds to the runt value for each of the Noskiffkas and indicates which skip count value to use based on the number of times counted by RC (11).

Next, <END> is a mark indicating the end of each table, and a negative number or the like is used. FIG. 3(b) is a diagram illustrating details of the first step table ST3. In the figure, S O) to St (m) are numerical values stored in the first step table, and RC (11
) is a numerical value that determines the amount of change in the displayed numerical value (hereinafter referred to as step count value). However, in this case, for example, S, (1) < 5t (2) <-------・-< St(

In the figure, the condition 0≦RC< When Bk(1), the skip count value is 5k(1). Next, when the condition is: Bk(1)≦Re<Bk(2), the skip count value is set to 5k(2). Next, when the condition is Bk(ffi-1)≦RC, the skip count value is set to S, (i). FIG. 4(b) is a diagram illustrating the relationship between the step count value and the boundary value. This explains which step count value is selected from the relationship between the count value counted by RC (11) and the boundary value in the first step table. When <Bt(+), the step count value is set to 5t(1). Next, when the condition is B(1)≦RC<B, (2), the step count value is set to 5t(2). Next, in the condition Bt(II-1>≦RC, the step count value is S t (tx). FIG. 5 is a flowchart explaining the present invention in detail, and will be explained using the diagram. For example, , when the increase key (3a) is pressed, the panel controller (5) generates an interrupt signal to the processor (8) at regular intervals.Then, the processor (8)
It is determined whether information indicating that this is the second or subsequent interrupt that occurs when a key is continued to be pressed is added (hereinafter referred to as repeat mode) (8501). If the repeat mode is not determined, the count values of RC (11) and SC (12) are set to 0 (8503). Next, it is determined by the key code which display unit's numerical value has been changed, and the process corresponding to the key code is selected (850
7). This process corresponds to the display explained in FIG.
There is a process for the third display (lc), and in this case the first increase key (3a) has been pressed, so the first display (la
) are selected (8510). Next, it is determined whether the setting value of SC(12) described above is 0 (8512). In this case, since SC(12) is set to 0, it is determined to be 0. Next, if the set value of 5C (12) is determined to be O, the skip counter register (1) is set to 1 (Ss14
). Then, it is determined whether the first boundary value B, (1) from the first skip table indicates the end of the table (<END>) (!351B). Next, if it is not the terminal, set value of RC (11) and a, U
), and the setting value of RC(11) is B. (i) Determine whether it is smaller than (9518). If it is not smaller, add 11;1 (8520), and return to step 851B to repeat the above process. At this time, if the end is determined in step 8516, or if it is determined in step 8518 that the set value of RC(11) is smaller than Bk(t), the step count value 5k(
1) and set S, Ct) in SC(12) (
S522). In this case, the condition shown in Figure 4(a), O≦RC<Bk(1), applies, so SC(1
2) is set to 5k(1). Next, a description will be given by substituting numerical values for the conditions and the skip count value 5k(t). FIG. 6(a) is a specific example in which numerical values are substituted into FIG. 4(a), and the condition O≦Rc<B*(1) is changed to, for example, O≦RC<20, the skip count value S, Let (t) be 10. Conditions: B(1)≦RC<B, (2), 20≦RC<1
50, and the skip count value 5k(2) is set to 5. Next, set the condition, B(2>≦RC<B, (8), 150≦R
Let C<500 and skip count value 5k(3) be 3. Next, the conditions are: B, (Z-1)≦RC, 500≦RC, and the skip count value sk is 0.
shall be. Using the above example, first, from the condition O≦RC<20, the setting value of RC (12) and the skip count value 2
Compare 0. Then, RC(11) is 0 and this condition is satisfied, so SC(12) is set to 10. Next, if 5C (12) is set, set the step count register (h) to 1 (8524), read the first boundary value B, (1) from the skip table,
It is determined whether it indicates the end of the table (<END>) (852B). If not completed, set value of RC (11) and step 85
1B, (h) and determines whether the set value of RC (11) is smaller than B, (h) (8528). If it is not smaller, 1 is added to h (S30), and the process returns to step 8526 to repeat the above process. At this time, it is determined that the end is completed in step 8526, or the setting value of RC(11) is changed to Bt(
h), the next step (S534
) <9534). In this case, RC(11) is O, so Figure 4(b)
Since the condition 0≦RC<B, (1) applies, S, (
Select 1). Next, the conditions and step count value 5
The explanation will be given by substituting a numerical value for t(h). FIG. 6(b) is a specific example in which numerical values are substituted into FIG. 4(b), and the condition 0≦RC<B, (1) is set to, for example, 0≦RC<100 and the step count value is 510). 1
shall be. Conditions: B (1)≦RC<Bt(2), 100≦R
Let C<200 and step count value 5t(2) be 5. Next, set the conditions: B (2>≦RC<B, (3), 200≦RC<800
and step count value 5t(1) is 60. Next, the condition B, (11-1)≦RC is 800≦RC, and the step count value S t (m〉
is set to 100. Using the above specific example, first, the set value of RC(12) and the boundary value 100 are compared from 0≦RC<100. Then, since RC(11) is O, this condition is satisfied. Then, end at step 8526 or step 85
If it is determined in step 28 that the setting value of RC (11) is smaller than B, (h), it is determined whether the interrupt signal described above is due to the increase key or the decrease key (S532). In this case, Since the first increase key (3a) has been pressed, it is determined that the increase key has been pressed, and the step value 5t (h) is added to the value currently displayed on the first display (la) (853
4). In this case, S, (1) is added. in particular,
Taking Figure 6(b) as an example, the currently displayed value is 1
Add. Then, apply the newly obtained value to the panel controller (5
> (8538). Then, the first display (L
Only one of the numbers displayed in a) can be stacked. Further, if the first decrease key (2a) is pressed, in step 5532, it is determined that the decrease key is pressed, and the step value 5t is changed from the numerical value currently displayed on the first display (la).
(h) (S534) and outputs the value to the panel controller (5>).Next, if the first increase key (3a) continues to be pressed and a second interrupt occurs, step 5501 is determined to be in repeat mode as explained above, and RC(1
1 is added to the setting value of 1) (8505). At this time, since the setting value of RC(11) is initially set to O, the setting value becomes 1. Next, step 8507 to step 85 explained above
12 processes are executed. Then, in step 8512, it is determined that 5C(12) is not O. This is because, as explained in step 5522 above, SC(12) is set to 5k(1) (specifically, 10). Next, if it is determined that it is not 0, one is subtracted from the skip count value set in step 5522, and S C (1
2) (sbta). Specifically, it is set to 9. Then, the process ends. This is shown in Figure 4(a).
Based on the condition of 05 RC< B (1), 5k(i
) The interrupt signal is rejected by the number of count values, specifically, it is rejected up to 10 counts, so even if the first increment key (3a) is kept pressed, the interrupt signal will not be accepted for 10 interrupts. Then, the process ends at step 5513. Next, the first increase key (3a) is kept pressed and S C (t
Assume that the setting value of 2) is decreased by 1 and set to 0. Specifically, this is the 12th interruption after the key is pressed. Then, in step 5512, SC(12) is determined to be 0, and steps 8514 to 55 described above are executed.
20 and select the applicable skip value condition. Specifically, from FIG. 6(a), the condition 0≦RC<
20, and the skip count value is 10. Then, steps 8522 to 853B explained above
Execute the process. In this case, using the concrete example m6 diagram (b), 5, RC
The count value in (11) changes by only 1 until it reaches 100. Next, if RC (11) counts 154 times,
Executing the processes from step 9501 to step 5522 described above, and using a specific example, setting the skip count value 3 to SC(12) based on the skip count value condition of 150≦RC<500, and Step 8524~
Execute the process of step 5530, set the step count value 5 from the step condition of FIG. 6(b), 100≦RC<200, execute the process of steps 8532 to 8538, and display the Add 5 to the value displayed in . Next, the interrupt signal by the first increase key (1a) is 800.
If the skip count value O is counted twice, execute the process explained above and set the skip count value O to SC(12
). Then, a step count value of 100 is read from the step condition, 800≦RC, and 100 is added to the value displayed on the display (la) and displayed. Therefore, based on the number of interrupts when the increase key is held down, set the number of rejections (skip count value), and also decide how much to change the value when changing the scatter value. By setting a value (step count value) to change the value, the timing of changing the value will become progressively faster and the increment will become larger as the time elapses when the key is pressed, allowing you to reach the desired value quickly. It is possible. Although the above embodiment has been explained using the increase key, the process is the same and the effect is also the same even if the decrease key is used. Furthermore, since the table described above can be set arbitrarily, the timing and amount of change in numerical values can be arbitrarily set. Furthermore, in the above embodiment, the panel controller (5) generates an interrupt at regular intervals, but for example,
Using a timer provided in the processor (6), when an increase key and a decrease key (hereinafter collectively referred to as increase/decrease keys) are pressed, an interrupt is generated only once and a timer (not shown) is started. , From then on, the key state is determined every time the timer times up, and while the key is pressed, the count value of RC (11) is increased by one, corresponding to the key code in the same way as in the first embodiment above. It is also possible to perform processing to change the numerical value. A second embodiment in this case will be described below using a flowchart. FIG. 7 is a flowchart explaining the second embodiment. In this case, if the increase/decrease key is pressed and the processor (B) detects the interrupt signal, it will execute the following process. The processor (6> cancels the timer (870)
1) Start a timer (8703). Next, remember which increase/decrease key was pressed5705>
, R C (11) and SC explained in the first embodiment above
(12) is set to 0. Then, processing similar to the processing from step 8507 to step 5540 described in the first embodiment is executed, and the numerical value is changed based on the predetermined skip count value and step count value (8709).
. Next, when the timer reaches a predetermined time, the state of the increase/decrease key is determined, and if the key is on, the RC (11
) and sets RC(11) to 1 (S71
2). Then read the memorized key code 5714
), the process of steps 8507 to 5540 similar to those of the first embodiment described above corresponding to the key code is executed (871B), and the numerical value is changed based on the predetermined skip count value and step count value. From now on, every time the timer is up, the key state is determined, and if it is on, RC(11) is incremented by 1, and if the processing from step 8507 described above is executed, the interrupt by the increase/decrease key may be performed only once. . Also, what is written to the step table is not the change when a key is pressed, but the magnification of the change. This is done by determining the minimum increment/decrement based on the nature of the numerical value, and writing the change as the value shown below. Also good. <Change amount> - <Minimum increase/decrease amount> x <Magnification read out from the step table> Furthermore, by using a CRT as a display, this process can also be used for the moving speed of the cursor. It can also be used to change the size of a circle cursor or square cursor. In other words, the present invention is effective when changing what is displayed to quickly reach the target. [Effects of the Invention] As described above, according to the present invention, the timing of addition and subtraction is determined based on the repeat count value, which is the cumulative value of interrupt signals generated at a predetermined timing when an increase key or a decrease key is operated. Since the size of the addition/subtraction value at that time can be set arbitrarily, for example, the timing of changing the displayed object can be initially slowed down, then it can be made faster gradually, and the width of change can be gradually increased. As a result, the speed of change of the displayed object can be seen visually, and the effect that the target displayed object can be reached quickly is obtained.
