Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling the setting of numerical values in electronic equipment, and more particularly to a method of setting a predetermined numerical value by a rough operation.

[0002]

2. Description of the Related Art In the operation of electronic equipment, many kinds of numerical values are often set. A rotary knob, a button, etc. are used to set the numerical value, and the numerical value is continuously changed to set the numerical value in the device. In such an operation of continuously changing the numerical value and finally setting the numerical value, it is often desired to set a predetermined numerical value. For example, in setting the voltage, the voltage is set to 0V during the operation of changing the numerical value from positive to negative.

In FIG. 6, the voltage is reduced by 0.1,
This is a conventional example in which it is desired to temporarily set the set value to 0V or a value that does not become lower than 0V. This is often done when the number has a special meaning, such as often using 0V as the reference number. When changing the value by turning the rotary knob, it is necessary to carefully operate the rotation of the rotary knob when approaching 0 V, and rough operation will exceed 0 V and reach a negative value. Not easy to set to.

[0004]

When a variable value is continuously changed by a rotary knob or the like to set an arbitrary numerical value in an electronic device,
When setting a predetermined numerical value having a specific meaning such as a reference numerical value often used as a set numerical value, conventionally, when the predetermined numerical value is approached, the rotary knob is carefully operated to change the numerical value.

Therefore, an object of the present invention is that the predetermined numerical value can be easily set without any special operation while keeping the same operational feeling, and any other numerical value can be set. It is to provide a numerical value setting control method.

[0006]

The present invention is a method for controlling the numerical setting of an electronic device, which comprises the following steps. In the first step 11, the numerical value is changed with a rotary knob or the like. In the second step 12, it is judged whether the changed numerical value exceeds a predetermined numerical value. In the third step 13, if the changed numerical value does not exceed the predetermined numerical value, the changed numerical value is set as a new numerical value in the electronic device, and the process returns to the first step 11. In the fourth step 14, when the changed numerical value exceeds the predetermined numerical value, this predetermined numerical value (or the final numerical value before the change) is set in the electronic device as a new numerical value. In the fifth step 15, it is judged whether the changing direction of the changed numerical value is the same after the fourth step 14. In the sixth step 16, if the changing direction of the numerical value is the same, the setting of the electronic device is kept at the predetermined numerical value (or the final numerical value before changing) for a predetermined time, and then the process returns to the first step 11 and the changing direction of the numerical value is the same. If not, the process returns to the first step 11.

[0007]

2 and 3 show one embodiment of the method of the present invention, in which the numerical value of the voltage is decreased by 0.1 by changing the numerical value with a rotary knob or the like, and the numerical value is reduced to 0.
This is an example in which the change is temporarily stopped at a value that does not become lower than V and 0V. At this time, 0V is set as the predetermined numerical value. In either case, when the value is decreased by 0.1 and 0.071 V is exceeded, the next value is −0.
It should be 029V. So in Figure 3,
When the numerical value is 0.071 V and the numerical value is changed by rotating the rotary knob for a predetermined time, for example, 1 second, the numerical value change stops. In FIG. 2, the numerical value is 0.0 as well.
At 00V, even if an attempt is made to change the numerical value for a predetermined time, the numerical value stops changing. Since the numerical value does not change even if the rotary knob is rotated for a predetermined time after the numerical value stops changing, the numerical value can be easily set to the predetermined numerical value by stopping the rotation here. It is not necessary to rotate the rotary knob particularly carefully for setting the predetermined numerical value. If the rotary knob is continuously rotated in the same direction even after the change of the numerical value is stopped and the numerical value is continuously changed, the numerical value restarts after a predetermined time and exceeds the predetermined numerical value 0V to reach a negative numerical value. Further, if the rotary knob is rotated in the opposite direction after the stop of the numerical value change, the numerical value immediately changes in the opposite direction. Here, an example is shown in which the numerical value is decreased, but it is also possible to increase it.

FIG. 1 shows a flow chart of the method of the present invention. In the first step 11, the numerical value is changed continuously. To change the numerical value, a well-known technique such as rotating a rotary knob attached to the electronic device or pressing a predetermined button may be used. In the second step 12, it is judged whether the changed numerical value exceeds a predetermined numerical value. If it is determined that the value does not exceed the limit, the process proceeds to the third step 13, the changed numerical value is set in the electronic device as a new numerical value, and the process returns to the first step 11. When it is determined in the second step 12 that the predetermined value is exceeded, the process proceeds to the fourth step 14 to set the predetermined value (or the final value before changing the value) in the electronic device as a new value. In the fifth step 15, it is judged whether or not the rotary knob continues to rotate in the same direction, that is, whether the direction in which the numerical value is to be changed is the same even after the numerical value stops changing. Return. If the direction of numerical value change is the same, the process proceeds to the sixth step 16 to measure a predetermined time, and if the predetermined time does not elapse, the process returns to the fifth step 15 to determine the rotating direction of the rotary knob, and if the same direction continues, the process continues. The predetermined time is counted, and when the predetermined time elapses, the process returns to the first step 11.

FIG. 4 shows an embodiment of an electronic device 40 to which the method of the present invention is applied. The numerical value to be set is changed by the rotary knob 41. Of course, a button or the like may be used instead of the rotary knob. By using the key 42 on the front panel of the electronic device 40, a frequently used reference numerical value or the like is set as a predetermined numerical value. This predetermined numerical value is stored in the random access memory (RAM) 44. The read only memory (ROM) 43 stores a program for executing the method of the present invention. The microprocessor 45 stores this program in the ROM 4 as needed.

FIG. 5 shows an embodiment for implementing the present invention without using a microprocessor. The rotary knob 50 is used to continuously change the numerical value. Of course, any device that can change the numerical value such as a button may be used. The rotation of the rotary knob is digitized by the decoder 52, and the value of the up / down counter 54 is increased or decreased. A predetermined numerical value is inputted to the comparator 56 as a comparative numerical value, and the output of the up / down counter 54 is received and compared with the predetermined numerical value. If up / down counter 5
When the output of 4 coincides with the predetermined value or exceeds the predetermined value, the comparator 56 stops the up / down counter 54 from increasing or decreasing for a predetermined time, and outputs the predetermined value or the final value before changing the value. Output to the display device. On the other hand, the comparator 56 outputs the output of the up / down counter 54 as it is to the display device 58 when the output of the up / down counter 54 does not match the predetermined value or does not exceed the predetermined value. The change in the numerical value due to the rotation operation of the rotary knob when the change in the numerical value is stopped is the same as described above. The display device 58 displays the output of the comparator 56 as a numerical value.

[0011]

According to the method of the present invention, in setting the numerical value of an electronic device, when the set numerical value is continuously changed by a rotary knob or the like, a predetermined numerical value or a numerical value which does not exceed the predetermined numerical value is changed. To stop temporarily. Therefore, by setting a numerical value with a special meaning, such as a reference numerical value that is often used, as the predetermined numerical value, the predetermined numerical value can be applied to electronic devices even with rough operation while maintaining the same operational feeling as setting any other numerical value. Can be set. Of course, any other numerical value can be set with the same operation feeling.
