Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to a numerical value setting mechanism used in combination with equipment and the like.

[Conventional technology and its problems]

Conventional numerical value setting mechanisms use a counter to count pulses that are generated in proportion to the rotation angle of the knob.
This is a mechanism that displays and outputs the count value as a set value.

The operation of this count is equivalent to the operation of an adder that adds 1 to the set value for each pulse generated by the knob.

In the case of such a conventional numerical value setting mechanism, it may be difficult to provide appropriate operability due to the relationship between the number of pulses generated per rotation of the knob and the width of the numerical value to be set.

First, the pulse per rotation of the knob is 50~
Approximately 100 pulses/rotation is appropriate; if much more pulses than this are generated, it will be difficult to operate on a pulse-by-pulse basis.

Under this condition, when setting a value between 0 and 10000,
To change the value from the minimum value to the maximum value, you have to turn the knob 100 to 200 times, making it very difficult to operate.

In actual applications, there is often no need to vary the density from 0 to 10,000 with the same density, but in conventional methods, there is no room for improving operability even with such conditions.

[Means for solving problems]

The present invention eliminates these drawbacks and provides a means for efficiently setting numerical values only by operating a knob. an adder that adds an increment △D to D and outputs a new set value D=D+△D, and the output is input as the set value;
The output of this adder (D=D+△D) is supplied to a display section, the output of the adder (D=D+△D) is supplied, a predetermined functional relationship f is stored, and the output △D=f (D) consists of a fixed storage device (read-only memory) that is supplied to the adder as an increment.

A second aspect of the present invention is such that a speedometer is added to the above-mentioned configuration to detect the rotational speed of the knob and input the detected rotational speed to a fixed storage device.

In other words, the function value to be stored in the fixed storage device is divided into multiple regions, and the function changes in each region are set and stored so that they are independent of each other, and the rotational speed of the knob is detected and fixed using a speedometer. As an input to the storage device, one of the plurality of regions is selected as an input to the plurality of regions, the region in which the function change is large as the speed is high, and the region in which the function change is small as the speed is low. The output corresponding to the input value supplied from the adder is supplied to the adder as an increment of the set numerical value.

[Operation] When the knob is turned, a number of pulses corresponding to the rotation angle are generated and are input to the adder. The adder adds the increment △D output from the fixed storage device to the set value D for each pulse to calculate D=D+△D, and inputs it to the adder itself, the fixed storage device, and the display section. Repeat.

The fixed storage device has an increment △ according to the set value D.
In order to output D, the functional relationship f is stored in advance as ΔD=f(D).

By setting this functional relationship f in advance according to the purpose, it is possible to provide arbitrary operability.

If a function value that satisfies f(D)=D+1 as the functional relationship f is stored in a fixed storage device, for example, seven pulses need to be generated for the set value to change from 0 to 127. A wide range of multi-digit setting values can be set or changed efficiently.

In actual use, a value between 0 and 10000 is set, but
0 to 10 in 1 increments, 10 to 100 in 10 increments, 100
Assuming that the settings can be set in increments of 100 up to ~1000, and in increments of 1000 from 1000 to 10000, in the equivalent model of the counter shown as the conventional technology, add a function to change the value to be added depending on the set value. This improves operability.

With this configuration, it takes 11 + 10 + 10 + 10 = 41 pulses, or about 1 pulse, to change the value from 0 to 1000 using the knob with 50 pulses per rotation.
All it takes is rotation, and operability is greatly improved.

Furthermore, depending on the application, it may be desirable to set all values in increments of 1.

When setting in increments of 1, there is a psychological necessity to turn the knob slowly, so if you detect the speed at which you turn the knob, that is, the frequency of the pulse, and change the increments between fast and slow times, It is possible to achieve both good operability and fine increments.

Also, assuming that the speed detection section outputs 0 when the pulse rate is slow and 1 when the pulse rate is fast, if this is added to the most significant digit of the input, the input when the rate is slow is 0 to 1000, and the input when it is fast. can be like 10000-20000.

With this configuration, if you turn the knob above a certain speed, you can easily set the approximate value as described above, and when you get close to the set target value, the knob will naturally slow down, unlike the conventional method. You can set a numerical value by changing the value in 1 increments.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a numerical value setting mechanism to which the present invention is applied. When knob 1 is turned, a number of pulses corresponding to the rotation angle (including the case of multiple rotations) are generated, and the adder 2 is input. This adder 2 for each of the above-mentioned pulses:
Add the set value increment △D output from the fixed storage device (read-only memory, hereinafter referred to as ROM) 3 to the set value D to create a new set value D = D + △
Calculate D. This output is input to the adder 2 itself, as well as to the ROM 3 and display section 4.

As shown in FIG. 2, the ROM 3 stores function values of D and ΔD such that a set numerical value increment ΔD that increases or decreases in response to the set numerical value D changes along a pre-planned curve.

With this configuration, the output of the adder 2, that is, the set numerical value displayed on the display section 4, is
When the set value D is small, set value D in small increments.
When is large, it will increase or decrease significantly.

FIG. 3 is a block diagram showing another embodiment. In this example, the ROM 3 has a preset value, and as shown in FIG. The set numerical value increment △D that increases or decreases in response to D is determined by the pre-planned curve (1
D, △
The function value of D is memorized. The areas are divided based on the rotational speed of knob 1. The rotational speed of knob 1 is detected by the speedometer 5 and inputted to the ROM3, and the ROM(3) uses this signal to divide the plurality of areas. One of them is selected, and ΔD corresponding to D in that area is read out from the input D from adder 2 input at the same time and becomes input to adder 2. At this time, the higher the rotation speed of the knob, the more the increment △D
The lower the region (R in FIG. 4) where the change is, the smaller the region (P in FIG. 4) is selected. Therefore, the output of the adder 2, ie, the set numerical value on the display section 4, changes extremely rapidly when the rotation speed of the knob 1 is high, and changes slowly when the rotation speed of the knob 1 is slow.

With this configuration, the output of the adder 2, that is, the set value displayed on the display section 4, changes extremely rapidly when the rotation speed of the knob 1 is fast, and changes slowly when the rotation speed of the knob 1 is slow. .

In conventional mechanisms, the size of the set value increment must be selected by switching a switch, and since the set value increment is constant within the area corresponding to one switch, even if the rotation speed of the knob is increased, It was just a change in the set value.

In this example, regardless of the digit of the set value, if you turn knob 1 quickly, the set value will change much more rapidly in large increments along the function curve, and if you turn it slowly, the set value will change slowly in small increments. Therefore, fine adjustments can be easily made, and in any case, the changes are made over the entire range of set values.

Human psychology also means that if you want to change a setting value quickly, you turn the knob rapidly, and when you want to make a fine adjustment, you naturally turn the knob slowly. It is a perfect and extremely effective mechanism.

Additionally, in general, the numerical value setting mechanism itself is not used independently, but is constructed as a part of the equipment, and the above knobs and switches are usually built into the equipment body, and the size of the equipment Therefore, it is not uncommon to be subject to area constraints such as these. In situations like this, being able to completely eliminate the switch and use just one knob is actually a huge benefit.

Incidentally, all modern devices have some kind of computer mechanism built in, so operations such as the one shown in the diagram above, such as storing and reading a numeric value using a ROM, adding the result using an adder, and adding the result to each element. All commands to the system can be executed by programming the built-in computer, which has the remarkable advantage of increasing effectiveness without substantially changing the structure of the device.

〔Effect of the invention〕

As described above, according to the present invention, setting values over a wide range of multiple digits can be efficiently set or changed by operating only one knob without using a changeover switch, and in addition to improving work efficiency, The structural advantage is that the switch can be completely eliminated and only one knob is required, which saves area and volume of the equipment, making the equipment more compact.Furthermore, it is possible to add new equipment by utilizing the built-in computer in the equipment. It can be expected to have significant effects in terms of structure and design, such as having a series of functions performed on behalf of the user, and will greatly contribute to the development of equipment.
