Abstract

PROBLEM TO BE SOLVED: To mechanically simulate a feeling for click by controlling a driving force control means so that a movable operation portion imparts a click against the moving operation when the movable operation portion is operated by manual to arrive at a portion within a given range. SOLUTION: The range of torque generation (torque drive range) and the direction of torque generation in the torque drive range (torque along positive direction/torque along negative direction) are set beforehand according to the positions of a fader. When the fader is located within the torque drive range, a torque is generated in a motor in a direction depending on the fader position. When the fader is located outside the torque drive range, no torque is generated. If, for example, the fader is positioned just within a range after or before the value 50 (i.e., in a range of around 47-53 in a flat portion), no generation of torque occurs. If positioned in the vicinity of range of around 53-60, a torque along negative direction is exerted, and if positioned in the vicinity of range of around 40-46, torque along positive direction is exerted on the motor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter value operating device such as a motor fader used in a mixer or the like.

[0002]

2. Description of the Related Art Since a slide type variable resistor is inexpensive and durable, it is widely used as a numeric setting operator. Such a variable resistor is often provided with a mechanism (hereinafter also referred to as a click) for mechanically informing the position according to the purpose of use. For example, a variable resistor is a graphic
When used as an equalizer operator, the center of each operator is clicked so that the user can easily set flat characteristics. In addition, the variable resistor is a numerical input operator (hereinafter, referred to as a mixer) in the mixer.
When used as a fader, a click is often attached to a knob position corresponding to the standard value so that a standard value of a parameter assigned to each fader can be easily set.

In such mixers, one fader is often used as a common input operator for a plurality of types of parameters in order to reduce the size and cost of the apparatus. In this case, one of a plurality of types of parameters is selected and assigned to a fader, and thereafter, the fader is used as an operator for setting the value of the assigned parameter. In such a case, when calling the numerical value to be input for the selected parameter and setting it to the fader, the current knob position of the fader (hereinafter referred to as the actual position of the fader), that is, the variable resistor The called parameter value is made to correspond to the instruction value, but if the parameter value and the actual position of the fader are different, comfortable operation cannot be performed.

[0004] As a method for eliminating such a deviation between the actual position of the fader and the called parameter value, a motorized fader is widely used.
An example of this motor fader is shown in, for example, JP-A-6-275410. The motor fader is a variable resistor having a motor for moving a fader position (hereinafter, referred to as a fader position), and can be moved by a motor so that the fader position matches the called parameter value. Then, after the called parameter value matches the fader position, the motor stops driving, and when the knob is manually operated, the parameter value is input according to the manually operated position.

[0005]

Although the motor fader can be set by a motor drive and set by a manual operation, the conventional motor fader does not have a click feeling at the time of the manual operation.
It was difficult to intuitively know the amount of parameter change. It is not impossible to provide a click feeling (a feeling of being caught by a moving operation; the same applies hereinafter) by simply providing a mechanical click portion at an arbitrary knob position on the motor fader. In this case, the fader knob cannot be moved smoothly when driving the motor, which makes the control of the motor complicated and the position where the click is desired to be changed depending on the parameter to be assigned. Does not use mechanical clicks.

The present invention has been made in view of the above problems, and has as its object to simulate a mechanical click feeling in a parameter value operation device such as a motor fader which can be operated automatically and manually. I do.

[0007]

In order to solve the above-mentioned problems, a parameter value operation device according to the present invention provides a physical quantity having a size corresponding to a position at which a manually operable movable operation portion is moved. A variable element that outputs, a power source that generates a driving force, a transmission mechanism that moves the movable operation unit by applying a driving force generated by the power source to the variable operation unit, and the movable operation unit is movable. When the movable operation unit is located within a predetermined position range provided in the range, a driving force for causing an operator to recognize the position range through the movable operation unit, for example, a driving force for generating a catch for a moving operation Driving force control means for controlling the variable operation element to act on the movable operation section, and corresponding means for causing a physical quantity output from the variable element to correspond to a parameter value. In this parameter value operation device, when the movable operation unit is manually operated or the like and reaches a predetermined position range, a driving force acts on the movable operation unit to cause the movable operation unit to be caught by the control of the driving force control unit. Click feeling can be produced.

[0008] The driving force control means includes a driving force so that the movable operation portion moves toward a stable position provided in the position range when the movable operation portion is within the predetermined position range. Can be configured to control the operation of. With this configuration, when trying to escape from the stable position, a driving force acts to return the movable operation unit to the stable point.
An operator can recognize the existence of the stable point as a feeling of being stuck in the moving operation, and can produce a positioning mechanism that can easily set the movable operation unit to a desired position. In addition, for example, if the driving force applied to the movable operation portion in the predetermined position range is configured to increase as the position approaches the stable point, a favorable tactile click feeling can be produced at the time of positioning.

Further, the above-mentioned parameter value operating device is configured to determine, for the predetermined position range, at least one of the position of the position range, the number of the position ranges, and the width of the position range. There is provided first setting means for setting setting information, and the driving force control means can be configured to control the driving force acting on the movable operation section based on the first setting information.
For example, a plurality of position ranges may be set, and the driving force control means may set the strength of the driving force applied to the movable operation unit in accordance with each of the plurality of position ranges. Thus, it is possible to notify the operator of a difference in the importance of each position range or the like based on the strength of the feeling of being caught in each position range. Further, for example, it is possible to obtain a desired operation range of the movable operation unit based on the state of the input signal level or other parameters, and set a boundary of the operation range as the position range. This makes it possible to adaptively set the position range according to the input signal level and the state of other parameters, thereby informing the operator of the desired operation range with a sense of being caught by the moving operation. Further, for example, a storage unit for storing the previously set operation position of the movable operation unit is provided, and the previous operation position of the movable operation unit stored in the storage unit in the storage unit is set as the predetermined position range. Can be configured. This makes it possible to easily notify the operator of the previously set operation position of the movable operation unit by the sense of being caught by the moving operation.

The above-mentioned parameter value operating device may further comprise a second setting information for determining at least one of a direction and an intensity of a driving force to be applied when the movable operating portion is in the predetermined position range. The driving force control means can be configured to control the driving force acting on the movable operation section based on the second setting information.

Further, the parameter value operating device includes a selecting means for selecting, from among a plurality of kinds, types of parameters for causing the corresponding quantity to correspond to the physical quantity output from the movable element. And at least one of the second setting information is set in accordance with the type of the parameter, and the driving force control means performs the setting based on the setting information corresponding to the type of the selected parameter. The driving force acting on the movable operation section can be controlled. This makes it possible to produce a suitable feeling of clicking (clicking) characteristics that matches the characteristics of the types of parameters.

The above-mentioned correspondence means can be configured to make the physical quantity correspond to the parameter value so that the change amount of the parameter value with respect to the movement amount of the movable operation portion is small in the predetermined position range. As a result, the change in the parameter value can be reduced for the movement in the predetermined position range, so that it becomes difficult to set the parameter value corresponding to the predetermined position range in order to provide a feeling of being caught in the predetermined position range. it can.

According to another aspect of the present invention, there is provided a parameter value operation device according to the present invention, wherein a variable element for outputting a physical quantity in accordance with a position at which a manually operable movable operation unit is moved;
A power source for generating a driving force, a transmission mechanism for moving the movable operating portion by applying a driving force generated by the power source to the movable operating portion, and a movable range of the increasing operating portion are divided into a plurality. And control means for controlling the driving force toward the switching position set in each divided range to act on the movable operation section. Thus, the function of the changeover switch of two or more stages can be easily realized using the variable element.

In the fader position control of the motor fader, the position-torque table, position-parameter value table, and parameter-value-position table are combined and used as one set for each type of parameter.
This combination is described in a table correspondence map described later. For example, the combination shown in FIG. 4 is a combination for performing volume control without giving a click feeling, the combination shown in FIG. 5 is a combination for giving a click feeling at the center position and mainly performing pan control, and FIG. The combination shown is 3 clicks
The following shows the combinations when there are multiple locations. Several types of these tables are prepared in advance by changing the click point, the number of clicks, the click width, the click strength, and the like, and each table is assigned a table number. Then, according to an instruction from the click feeling change operator 82, the click point, the number of clicks,

As shown in FIG. 7, the table correspondence map is a map for describing which table is used in combination in accordance with the type of the parameter.
When "volume" is selected as the parameter type, the combination of each table of table number 1 shown in FIG. 4 corresponds, and when "pan" is selected, the combination of each table of table number 2 shown in FIG. 5 corresponds. Is shown. The contents of this table correspondence map can be rewritten by the above-mentioned click feeling change operator 82.

Although not shown, the memory 9 has a register for storing the type of the parameter currently operated by the fader, and whether or not the automatic control is currently performed. MV flag (MV = 1: under automatic control, M
V = 0: under non-automatic control), and an area for storing other necessary registers.

The operation of this embodiment will be described below. The apparatus of this embodiment handles input signals of 8 channels, and the motor faders ₁₁ to 8 for 8 channels are used.
Although ₁₈ is provided, in the following description, for simplicity, only one channel of the motor fader (reference numeral 1) will be described.

First, a schematic operation will be described. In this embodiment, the parameter type is selected by the parameter selection operator 81 and assigned to the motor fader 1. Now, when a parameter value is input from the outside via the external input terminal 10, if the parameter type specified from the outside is the same as the parameter type assigned to the motor fader 1, the knob of the motor fader 1 is used. Move the position with automatic control. That is, the actual position of the knob 13 of the motor fader 1 is moved to a position corresponding to the input parameter value with reference to the parameter value versus position table (hereinafter, the actual position of the knob 13 of the motor fader 1 is referred to as " Actual position "). During this movement, control is performed so as not to give a click feeling. On the other hand, if the type of parameter specified from the outside is different from the type of parameter to be set, automatic control is not performed.

On the other hand, when a click feeling is produced by manually operating the motor fader 1, for example, as shown in FIG.
Generates motor torque. In the example of FIG. 1, a click feeling is produced as a point where the fader position and the parameter value are both "50". The effect of the click feeling is provided by applying a torque to the motor near the click point. The applied torque is determined by the current actual position of the fader. That is, in a predetermined vicinity range around the click point, the force acts toward the click point,
Apply torque to the motor. At the click point, if necessary, a short flat portion (portion without torque) is provided to stabilize the operation.

Specifically, according to the fader position, a range in which torque is generated (torque driving range) and a direction in which torque is generated in the torque driving range (torque in the forward direction / torque).
If the fader position is within the torque drive range, the motor generates a torque in the direction corresponding to the fader position, and if the fader position is out of the torque drive range, the torque is reduced. Does not occur. In FIG. 1, no torque is generated when the fader position is in the range immediately before and after 50 (positions 47 to 53 in the above-described flat portion), and in the vicinity range (torque driving range) in positions 53 to 60. Negative torque is applied, and positive torque is applied in the vicinity (torque drive range) in the 40th to 46th positions. Therefore, when a fader is manually operated, the operator feels or feels no torque depending on the operation position of the fader, and thus feels a mechanical click feeling on the fader.

When performing the above-described control of assigning a click point, it is necessary to automatically adjust the distribution of output parameter values so that parameter values adjacent to the click point do not fall within the click range. That is, torque control is performed for the click point “50” in the range of the fader position of the 40th to 60th positions, but the fader position corresponds to the parameter value as it is in a linear relationship as shown in FIG. If so, it becomes impossible to set a parameter value in the range of 40 to 60. Therefore, the fader position and the parameter value are associated with each other in a relationship as shown in FIG. In other words, in the range where the fader position is around the click point,
The corresponding parameter value is kept unchanged. As a result, the parameter values output corresponding to the fader position have a distribution as shown in the upper part of FIG.
(A parameter value close to) can be prevented from being included in the click range.

Hereinafter, the operation of the apparatus of this embodiment will be described with reference to the flowchart. FIG. 8 shows a parameter selection operator 8
6 is a flowchart illustrating a parameter selection process that is started when the user operates No. 1; When the parameter selection is performed, the current parameter type is switched to the selected parameter type (step S101). If the fader position corresponding to the switched parameter value is different from the actual position of the current fader, the fader is moved to the fader position corresponding to the switched parameter value by automatic control to match the two. , The MV flag is set to "1" (step S102).

FIG. 9 is a flowchart showing a parameter value change instruction receiving process which is started when a signal to change a parameter value is received. The computer 7 rewrites the parameter value stored in the memory 9 to the instructed value in accordance with the parameter value change instruction signal received from the outside via the external input terminal 10 (Step S).
201), the designated parameter value is output to the signal processing circuit 5 (step S202), and the signal processing according to the parameter value is performed in the signal processing circuit 5. At this time, if the designated parameter type is the type of the parameter currently assigned to the fader (step S203), the parameter value must be reflected in the fader position. In order to move the fader to the fader position corresponding to the parameter value of the parameter, the MV flag is set to "1" (step S204). Note that the parameter change instruction signal is externally input to M via the external input terminal 10.
In addition to those indicated by the IDI signal and the like, not shown,
The instruction may be made from the panel.

FIG. 10 is a flowchart showing the procedure of a click change process started when the click feeling change operation element 82 is operated. Click points about the click feeling,
When the change of the number of clicks and the click width is instructed (step S301), the position-torque table for the current parameter type in the table correspondence map,
The table numbers of the position-to-parameter value table and the parameter value-to-position table are changed to the table numbers corresponding to the change instructions (step S302). If the change of the clock strength is instructed (step S30)
3) Or, after the processing of step S302 is completed, the table number of the position-torque table of the current parameter type in the table correspondence map is changed to the table number corresponding to the change instruction (step S304).
As described above, by rewriting the table correspondence map shown in FIG. 7, it is possible to arbitrarily change the torque characteristic of the motor for producing a click feeling with respect to the type of parameter.

FIG. 11 is a flowchart showing a fader position control process of the motor fader executed at predetermined time intervals by a timer interrupt. When there is a timer interrupt,
The current actual position of the motor fader 1 is detected (step S
401) Then, it is determined whether the MV flag is "1", that is, whether the automatic control is being performed (step S402). If the automatic control is being performed, a process of moving the fader position to a fader position (hereinafter, referred to as a target position) corresponding to a parameter value specified from the outside is performed without simulating a click feeling. That is, a target position corresponding to the parameter value is calculated, and it is determined whether the target position matches the current actual position of the motor fader 1 (step S40).
3). The calculation of the target position corresponding to this parameter value is as follows:
This is performed by referring to a position versus parameter value table (such as (c) in FIGS. 4 to 6) for the parameter.

If the target position does not match the actual position, the difference between the two is determined by "target position-actual position", and the sign is determined (step S404). If the difference is a positive value, a torque command voltage V _REF corresponding to the magnitude of the difference between the actual position of the fader and the target position is given to the motor driver 2 to control the rotation of the motor in the normal rotation direction ( Step S40
6) Move the fader position toward the target position.
On the other hand, if the difference is a negative value, a torque instruction value V _REF corresponding to the magnitude of the difference between the actual position of the fader and the target position is given to the motor driver 2 to control the rotation of the motor in the reverse direction. (Step S405), the fader position is moved toward the target position. Steps S405 and S40
In 6, the motor is controlled with the torque command voltage V _REF according to the position difference. Therefore, the torque command voltage V _REF increases when the difference is large, and decreases when the difference is small. If the difference between the target position and the fader position is 0, the movement of the fader position is stopped, the MV flag is set to "0", and the automatic control is terminated.

If the target position and the actual position of the fader already coincide with each other in step S403, it is not necessary to automatically control the motor fader 1, so that the MV flag is reset to "0" and the processing is performed. (Step S4)
07).

On the other hand, if the MV flag is not "1" in the determination in step S402, that is, if the automatic control is not being performed, the motor fader 1 is manually operated to input a desired parameter value. The operation-set parameter values are sequentially sent to the signal processing circuit 5 for processing. In the case of this manual operation, a click feeling is given by a motor control at a predetermined click point. First, a parameter value corresponding to the actual position of the manually operated motor fader 1 is determined with reference to the position-to-parameter value table for the parameter, and the computer 7 determines the current parameter value in the memory 9 for the parameter. Is rewritten (step S408), and the parameter value is sent to the signal processing circuit 5 (step S40).
9). Further, referring to the position-torque table, near the click point, the torque command voltage V corresponding to the current position is displayed.
_By controlling the rotation of the motor with _REF (step S41)
0), produces a click feeling.

For example, when "volume" is selected as the parameter type, control is performed according to the table of FIG. 4. In this case, as is clear from the position-torque table of FIG. Since the torque is "0" at any of the fader positions, click point assignment control is not performed. When "pan" is selected as the parameter type, the control is performed according to the table of FIG. 5. In this case, as is clear from the position-torque table of FIG. The click feeling addition control described above is performed with the position "50" as the click point. At this time, the parameter value output corresponding to the fader position is as shown in FIG. It is possible to prevent a value near “50” from being included. When the parameter type is selected and control is performed according to the table of FIG.
As is clear from the position-torque table (a), 3
The click sensation addition control described above is performed with the fader position of the point as the click point.

As shown in the position vs. torque table of FIG. 12, the click feeling can be obtained by preparing a plurality of tables in which the magnitude of the torque generated by the motor is changed, selecting one of them as appropriate, and writing it to the table correspondence map. With this, the strength of the click strength can be changed.

When controlling to generate a plurality of click points, in addition to making the click strengths of the click points the same, as shown in FIG. 13, an important one of the click points is used. The click strength may be made stronger than the click strength of other click points. Thus, the difference in the importance of the click point can be indicated by the strength of the click feeling.

Further, in the above-described embodiment, the click strength in the vicinity of the click point is made constant (that is, the torque in the click range is made the same). As shown in the torque table, the characteristic curve may be such that a good feeling can be obtained. In other words, if the torque is increased as the fader position approaches the click point, the operator can obtain a sharp and responsive favorable click feeling that is strongly drawn at the click point.

In the above-described embodiment, the torque characteristics and the characteristics of the parameter values of the parameters are determined using the table. However, these may be calculated.

In the above-described embodiment, the click point is determined in advance by the position-torque table. However, the present invention is not limited to this. For example, when a parameter type is assigned to a fader, The parameter value when the same parameter type was previously assigned and changed to another type of parameter (that is, the previous value of the assigned parameter) is stored, and the fader corresponding to the previous parameter value is stored. The position may be generated as a click point. Thereby, the operator can easily know the previous value of the parameter by clicking feeling.

The parameter value operating device of the present invention can be used in the following manner. For example, it is assumed that “volume” is selected as the parameter type. At this time, if the level of the input signal is low, the output signal will not be distorted even if the volume is increased by the fader. However, if a large value is input as the input signal, the output signal will be distorted if the volume is increased. Therefore, for each value of the input signal, a fader position at which the output signal is distorted is obtained in advance, and a position-torque table with the fader position as a click point is prepared for each level of the input signal. When "volume" is selected as the parameter type, the level of the input signal is detected, and a table corresponding to the detected level is used instead of the table of FIG. This allows the operator to sense the set value of the volume at which the output signal is distorted with a click feeling of the fader, even for various input signal levels. The same can be applied to the case where it is necessary to change the current fader parameter value setting depending on the state of the parameter different from the parameter currently assigned to the fader. Points may be provided to notify the operator. In this way, the computer can automatically create a click point based on other parameters and the analysis result (such as the maximum level) of the input signal, and notify the operator of a desired operation range with a click feeling.

In the above description of the embodiment, the effect of the click feeling is described as the effect of clicking when the operation knob is positioned at a predetermined click point. However, the present invention is not limited to this. Instead, for example, when a certain point is approached, a driving force is applied in a direction in which the operation knob is repelled from the one point, so that the movement operation is caught and a click feeling may be produced.

FIGS. 15 and 16 show an embodiment in which a three-stage changeover switch is produced using the parameter value operating device of the present invention. As shown in FIG. 15, when the torque driving range is set so as not to stop at a portion other than the click point, it can be used as a switch. FIG. 15 shows an example of a switch for switching the three settings of A, B, and C. Between the point A and the intermediate point between A and B, a negative torque that always goes to the point A is generated. Between point B and point B, a positive torque is constantly generated toward point B.
The motor is controlled so as to always generate a negative torque toward the point B between the middle point of C and the positive torque toward the point C between the middle point of BC and the point C. . This allows the operator to manually operate the fader position to automatically move to any one of the points A, B, and C in accordance with the operated position and to stabilize the fader. Can be. In other words, such a three-stage switch can be realized by widening the click width and eliminating the fader position of the torque “0” in the above-described embodiment apparatus having three click points. FIG. 16 shows a position vs. torque table, a position vs. parameter value table, and a parameter value vs. position table when the three-stage changeover switch is produced.

[0047]

As described above, according to the present invention, the so-called click feeling at the time of manual operation is produced by the motor or the like, so that the click feeling at the time of manual operation can be obtained even in a parameter value operation device capable of automatic operation. , And the operator can intuitively recognize the operation amount. In the production of the click feeling, the position, the number, the strength, and the like can be freely set, and the click feeling according to the type of the parameter can be easily set. Further, by changing the strength of each of the plurality of click positions, it is possible to easily notify the operator of the importance of each click position by the strength of the click. Further, by setting the previously set parameter value at the click position, it is possible to easily inform the operator of the previous parameter value setting state with a click feeling. Further, by providing a click position at a boundary of a desired operation range corresponding to the state of an input signal or other parameters, the operator can easily be notified of the desired operation range with a click feeling. Further, since it is easy to turn on / off the effect of the click feeling, the fader can be moved smoothly by stopping the effect of the click feeling during automatic operation. It is also easy to realize the function as a multi-stage changeover switch.
