The adjustment amount can be reproduced with high accuracy and agility with a simple configuration, and the adjustment amount can be displayed with good visibility.

[0002]

2. Description of the Related Art A large-scale PA (Public Addr)
In the ess) device, the number of inputs and outputs of the mixing console is very large, and one person cannot adjust many faders and is apt to be erroneously operated. Therefore, a motor drive mechanism is provided on the fader operator, the fader position when the fader is manually operated to adjust the volume etc. is stored in the memory in advance, and the fader position information is read from the memory by the memory read operation. There has been a mixing console that automates fader operation by reproducing the fader position by driving a motor.

[0003]

The reproduction of the fader position in the prior art is performed by comparing the current position with the target position stored in the memory and performing feedback control of the fader position so that they match. It was Therefore, this requires a motor for driving the fader operator, a deceleration mechanism, a position detection mechanism for detecting the position of the fader operator, a servo circuit, etc., which complicates the configuration and makes the device expensive. There was a drawback. Further, since the fader position is reproduced by a mechanical operation, there are problems that the responsiveness is poor (it takes time to reach the target adjustment amount), and the reproduction accuracy deteriorates due to deterioration over time.

The present invention solves the above-mentioned problems in the prior art, and provides an adjusting device capable of reproducing the adjustment amount with high accuracy and agility with a simple structure and displaying the adjustment amount with good visibility. Is what you are trying to do.

[0005]

The invention according to claim 1 is

The rotary operation element is composed of a circular operation element, and an upper portion of the rotation operation element is exposed from the operation panel surface so as to be rotatable from the outside, and the adjustment amount display means is provided on the operation panel. The display control means changes the bar graph display on the adjustment amount display means to the operation direction of the rotary operation element. In addition, the bar graph display is controlled so that the rotational movement distance of the outer peripheral portion of the rotary operator and the change distance of the bar graph display are substantially equal to each other.

[0007]

According to the first aspect of the invention, the physical quantity to be adjusted is adjusted by electrical control without any mechanical operation, and the adjustment quantity is not displayed by the operator, but is provided separately. Since the controller itself is endlessly rotatable,
It is not necessary to drive the manipulator to reproduce the adjustment amount. Therefore, a motor for driving the manipulator, a speed reducer, a servo circuit, etc. are not required, and the structure is simplified and the cost can be reduced. Also, because it is adjusted by electrical control without mechanical movement, the response is quick,

Since the bar graph display is performed in a direction substantially along the direction, and the rotational movement amount of the operator and the change amount of the bar graph display are made substantially equal, it is possible to obtain an operation feeling close to that of a conventional fader operator.

[0009]

An embodiment of the present invention will be described below. Figure 2
Shows an embodiment in which the present invention is applied to a mixing console. The mixing console 10 includes a channel module 12 for each channel.
Each channel module 12 is provided with a rotary operator 14 corresponding to a conventional fader operator, a bar graph display 16 for displaying the amount of adjustment of the volume and the like by the rotary operator 14 in a bar graph, and other rotary knobs 18 and the like. It is set up.

As shown in an enlarged view in FIG. 2, the rotary operator 14 is made of plastic, metal or the like and has a disk shape, and the operation panel surface 2 is formed in the channel module 12.
It is arranged so as to be capable of endless rotation (rotating without dead end) in both forward and reverse directions around a shaft 22 arranged substantially parallel to 0. The upper portion of the rotary operator 14 is exposed upward from the operation panel surface 20, and the outer peripheral edge portion 24 is manually rotated in the directions of the arrows A and A'to move the rotary operator 14 to the arrow B. , B'direction. The bar graph display 16 is configured by arranging LEDs 18 on the operation panel surface 20 along the operation directions A and A ′ of the rotary operator 14.

Rotation operator 14 and bar graph display 1
A detailed configuration of No. 6 is shown in FIG. The length of the portion where the rotary operator 14 is exposed from the operation panel surface 20 is 60 to 100 mm.
The height and height are set to about 20 mm. A groove or protrusion 26 is formed on the outer peripheral edge portion 24 of the rotary operator 14 as a slip stopper when it is manually operated over the entire circumference. A gear 28 is formed on the side surface of the rotary operator 14 around the entire circumference of the shaft 22 in the circumferential direction. An incremental rotary encoder 30 is arranged in the channel module 12. A gear 32 is attached to the rotary shaft of the rotary encoder 30 and meshes with the gear 28 to rotate as the rotary operator 14 rotates. Note that, instead of the rotary encoder 30, the rotary operator 14 itself is used as a rotary plate of the rotary encoder to form a radial slit or a radial bright-dark pattern on its side surface with the rotary shaft 22 as a center.
It is also possible to adopt a configuration in which light is emitted from a light emitting diode or the like and the transmitted light or reflected light is received by a light receiving element. The bar graph indicator 16 is formed by arranging a plurality of LEDs 18 side by side on the exposed portion of the rotary operation element 14 so as to have a length similar to the length of the exposed portion. .

FIG. 1 shows a control configuration example (for one channel) for reproducing the volume adjustment amount, which is configured in the mixing console 10 of FIG. The memory 34 stores a plurality of types of programs in which the volume adjustment amount target values of the respective channels set by the operation of the operator are combined. The program selection key 36 is a key (up / down key etc.) for selecting any one of a plurality of types of programs stored in the memory 34. The program number selected here is displayed on the program number display 38. Is displayed.

When a desired program number is selected with the program selection key 36 and the recall key 40 is pressed, the read control means 42 outputs a read command and the contents of the corresponding program (volume adjustment amount of each channel) from the memory 34. Read the target value). The read target value is preset in the up / down counter 44.

The target value preset in the counter 44 is converted into an analog signal by the D / A converter 46, and the gain of the VCA (voltage control amplifier) 50 provided in the audio line 48 to which the audio signal is supplied is adjusted. Control to adjust the volume of this channel to the programmed value. The volume at this time is determined by the display control means 52.
Is displayed on the bar graph display 16. In this way, the volume adjustment amount stored in the memory 34 is reproduced.

The rotary encoder 30 is a rotary operator 1.
It rotates along with the rotation of 4, and outputs a two-phase pulse having a pulse number according to the rotation amount. The two-phase pulses are 90 ° out of phase with each other, and the phase relationship is reversed depending on the rotation direction. The forward / reverse detection circuit 54 determines whether the rotary encoder 30 is normally rotating (corresponding to an operation in the volume increasing direction of the rotary operator 14) or in reverse (corresponding to an operation in the same decreasing direction) depending on the phase relationship of the two-phase pulse. To detect.

When the rotary operator 30 is operated and a pulse signal is output from the rotary encoder 30, the counter 44 counts up the pulse signal from the preset value when forward rotation is detected, and reverse rotation is detected. If so, the pulse signal is down-counted from the preset value. As a result, the gain of the VCA 50 is increased / decreased from the preset value, and volume adjustment by manual operation is realized. In addition, the volume adjustment amount at that time is indicated by the bar graph display 16
Is displayed in. The counter 44 is configured to prevent overflow and underflow, and holds the upper limit value even if the count value reaches the upper limit value and further up count pulses are input, and reaches the lower limit value and further down count pulse. Even if is input, the lower limit value is retained.

To store the value readjusted by manual operation in the memory 34, the store key 56 is pressed. Then, the count value at that time is erased and written as the adjustment amount target value of the corresponding channel of the corresponding program of the memory 34 via the write control means 58 by erasing the old target value. When it is desired to leave the old program as it is and store it as another program, by designating a vacant program number with the program selection key 36 and pressing the store key 58, the program is stored in the designated program number.

As described above, according to the configuration of FIG. 1, since the reproduction of the volume adjustment amount is realized only by the electric control without involving the mechanical operation of the rotary operator 14, the rotary operator 14 is controlled. A motor, servo circuit, etc. for driving are unnecessary, and can be realized with a simple configuration. In addition, the rotary operator 14
Since it does not involve the mechanical operation of, the responsiveness is good and the target adjustment state can be obtained instantly. Also, there is no deterioration over time,
The target adjustment state can be reproduced with high accuracy. Also,
The re-adjustment operation by the rotary operator 14 after reproducing the target adjustment state can be performed with the same operation feeling as that of the conventional fader operator. If the reset key 60 is provided so that the values of the counters 44 of all the channels can be reset, the volume of all the channels can be once returned to 0 and readjusted from there.

Here, the relationship between the operation amount of the rotary operator 14 and the display amount of the bar graph display 16 will be described. When the rotary operator 14 is rotated by a finger, if the feeling that the finger actually moves and the change state of the bar graph are largely different, there is a feeling of strangeness and it is difficult to use. Therefore, the display control means 52 causes the bar graph indicator 1 to move in the same direction as the operation direction of the rotary operator 14.
The bar graph display 16 is controlled so that the lighting state of No. 6 is changed and the moving distance of the operating portion (outer peripheral edge portion) 24 of the rotary operation element 14 and the change distance of the lighting state are substantially equal. For example, the count number of the rotary encoder 30 per unit movement distance of the outer peripheral edge portion 24 is set to n count / mm,
The array pitch of the LEDs 18 of the bar graph display 16 is pmm
Then, if the display of the bar graph indicator 16 is advanced (or returned) by one step each time the n × p count is increased (or decreased), a sense of unity between the operation and the display is obtained, and the operability is improved. .

FIG. 4 shows a concrete example of changes in the operation amount and the bar graph display. First, it is assumed that the volume is 0 (the value of the counter 44 is 0). At this time, all bar graph displays are off. When the rotary operator 14 is operated with a finger in the direction of arrow A (volume increasing direction), the bar graph gradually lights in accordance with the rotation. Then, the portion originally located at the position a (position near one end of the exposed length) is located at the position b.
When reaching (the middle position of the exposure length), the bar graph lights up to half. When it is further turned to reach the position c (a position near the other end of the exposure length), all the bar graphs are turned on and the maximum volume state is reached. In this way, the rotary operator outer peripheral edge portion 24
The volume can be adjusted from the minimum to the maximum by moving the distance of the exposed portion of the. Further, since the movement amount of the outer peripheral portion 24 of the rotary operator and the display change amount of the bar graph display device 16 are substantially the same, a sense of unity between the operation and the display can be obtained.

FIG. 5 shows another arrangement example of the bar graph display 16. This is a bar graph display 16
In the vicinity of the rotary operator 14 and on the extension of the operation. By arranging in this way, the bar graph display does not become a shadow of the protrusion of the rotary operation element 14, the visibility is improved, and the width of the channel module 12 can be made narrow. Further, since the distance between the rotary operator 14 and the bar graph display 16 is as close as the embodiment of FIG. 2, the sense of unity between the operation and the display is not impaired.

In the above embodiment, the case where the present invention is applied to the sound volume adjustment is shown, but it can be used to adjust the equalizer amount and other parameters of the music signal. It can also be used for adjustment of physical quantities other than sound (for example, adjustment of light quantity by a light control desk).

[0023]

As described above, according to the first aspect of the invention, the physical quantity to be adjusted is adjusted by electrical control without any mechanical operation, and the adjustment quantity is displayed by the operator. Instead of performing the operation, the operating means itself can be rotated endlessly by the separately provided display means, so that it is not necessary to drive the operating element to reproduce the adjustment amount. Therefore, a motor for driving the manipulator, a speed reducer, a servo circuit, etc. are not required, and the structure is simplified and the cost can be reduced. In addition, since the adjustment is performed by electrical control without mechanical operation, the response is fast and deterioration with time does not occur. Moreover,
Even after reproduction, readjustment can be performed with the rotary operator.

Further, according to the second aspect of the present invention, the rotary operator is constituted by a substantially circular operator whose upper portion is exposed from the operation panel surface, and the adjustment amount is displayed by operating the operator. Since the bar graph display is performed in a direction substantially along the direction, and the rotational movement amount of the operator and the change amount of the bar graph display are made substantially equal, it is possible to obtain an operation feeling close to that of a conventional fader operator.
