Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a parameter control controller for setting and controlling various musical tone control parameters such as pitch bend amount, modulation, and volume in electronic keyboard instruments. The operability is improved by arranging on the operation panel a positioning part that becomes a fulcrum for the fingers when the palm comes into contact with it, and an operator placement part where the operator is placed so that the fingers can reach during this operation. was considered good.

<Prior Art> The following are known as conventional keyboard controls for modulation adjustment, pitch bend amount, etc.

For example, even if these controls are wheel type,
Even if they are lever types, they are all located on the keyboard's operation panel. This operator is arranged on an operation panel on the side of the keyboard and is operated by the player's left hand. The operation panel is a flat plate-like member,
A part of the wheel or the upper part of the lever is provided to protrude from this panel. The wheel is operated by touching and rotating the wheel, and the lever is operated by tilting the panel in one direction.

Control parameters were set and controlled using changes in resistance of a variable resistor connected to the wheel shaft or disposed at the base end of the lever.

<Problems to be Solved by the Invention> However, in such conventional electronic keyboard instruments, the operation panel is composed of only a flat surface, and the operators are arranged in this narrow panel part.
There was a problem in that the condition and posture of the hands and fingers were not constant during operation (the fulcrum was not fixed), and that skill was required to operate the controls quickly and with delicate sensations. Furthermore, there was nothing near the controls to guide the position of the controls, so the positions had to be confirmed each time.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a musical tone control controller that allows quick and delicate operation of operators.

Means for Solving the Problems> In the present invention, an operator for controlling musical tone control parameters is provided on an operation panel, and by operating and operating this operator with a finger, the musical tone control parameters are controlled. In the controller for musical sound control, on the operation panel, there is a positioning part on which the palm comes into contact and serves as a fulcrum for the fingers when the operator is operated, and the operator has a positioning part that forms a circle around the positioning part as a center. an operator arrangement section that is arranged to be able to slide freely in the direction;
This is a musical tone control controller having the following functions.

<Function> In the musical tone control controller according to the present invention, when the operator is operated, when the palm portion is brought into contact with the positioning portion of the operation panel, the fingers reach the operator.

The musical tone control parameters are controlled by sliding the operator in the circumferential direction using the positioning section as a fulcrum. In this way, the fulcrum during operation is determined, and since the operator slides around this palm, operation is extremely easy.

<Embodiment> Hereinafter, a first embodiment of a musical tone control controller according to the present invention will be described based on FIGS. 1 and 2.

In these figures, reference numeral 1'1 indicates the operation panel of the musical tone control controller.

As shown in FIG. 1, the operation panel 11 includes a flat surface portion 111, a concave recess 113 formed at a predetermined distance from the flat surface portion 111, and a concave portion 113 continuous from the recess 113. It has a convex portion 115 that is gently raised and formed in a convex shape. This convex portion 11
5 is disposed between the recess 113 and the flat surface portion 111.

Further, the width and shape of the recess 113 and the protrusion 115, the height of the protrusion 115, the recess of the recess 113, and the distance between the flat surface portion 11'1 and the recess 113 are determined by the operator's hand. It is set corresponding to the size of H.

A recess 11 is provided in the flat surface portion 111 of the operation panel 11.
Two arcuate grooves 131 and 132 are formed so as to extend substantially in an arc shape with 3 as the center.

Knobs lδ1 and 152, which are operators, are inserted and supported in these arcuate grooves 131 and 132, respectively, so as to be slidable along the direction of the grooves.

As shown in FIG. 2, these arcuate grooves 131 and 132 are formed to extend within a predetermined angular range centered on a predetermined position of the convex portion 115 (the axial position of a rotary volume to be described later). These arcuate grooves 131, 132
The distance between them is set to, for example, the difference in length between the middle finger and the index finger.

Furthermore, the knobs 151 and 152 both have circular heads on which the player (operator) can place his or her fingers and slide them in the circumferential direction within the arcuate grooves 131 and 132. be.

Furthermore, these knobs 151 and 152 are connected to the first arm 1 (!I) disposed on the back side of the operation panel 11.
It is connected (press-fitted, fixed) to each tip of 71 and 172, respectively.

In FIG. 1, the base end of each arm 171, 172 is connected to the shaft 191a, 192 of the rotary volume 191, 192.
Each is connected to a. rotary volume 19
1 and 192 are each fixed to the chassis 21. The chassis 21 is suspended from the back surface of the operation panel 11.

A return spring 23 is wound around a shaft 191a to which the base end of the arm 171 is connected, and this return spring 23 urges the arm 171 to return to the center point.

251 and 252 are stopper rubbers to which both ends of the return spring 23 are locked.

Reference numerals 271 and 272 are stoppers that restrict the movement of the knobs 151 and 152, and restrict the rotation range of the knobs 151 and 1520.

The rotary volumes 191 and 192 are used to control parameters for musical tone control, such as pitch bend amount and volume, respectively.

Further, the recessed portion 113 constitutes a positioning portion that serves as a fulcrum for the fingers, with which the lower part of the palm comes into contact when operating the knobs (operators) 151, 152. In addition, when the lower part of the palm of the hand abuts against the recess 113, the central portion of the palm comes into contact with the convex portion 115. Note that, as shown in FIG. 2, this convex portion 113
A thumb relief portion 115a is formed at the bottom. This is to prevent it from getting in the way during operation.

Knobs 151 and 152 are arranged on the flat surface portion 111, and constitute an operator arrangement section. knob 151
, 152 are arranged so as to be slidable approximately in the circumferential direction of a circle centered on this positioning recess 113.

As described above, since the recessed part 113 and the convex part 115 are formed on the upper surface of the operation panel 11, when the left hand is placed on the controller, the lower part of the palm is in close contact with the recessed part 113 and the central part of the palm is in close contact with the raised part 115. Stabilize. In this state, the knob 151 can be operated with the tip of the middle finger, and the knob 152 can be operated with the tip of the index finger.

Therefore, simply by placing your left hand on the controller, you can reliably operate multiple operators (151, 152) at the same time without checking the positions of the operators (knobs 151, 152). . In this case, the operating direction of the knobs 151, 152 is in the circumferential direction with the recess 113 as a rotational fulcrum, so the operation can be performed smoothly. This is because there is no need to extend and retract the fingers as would be the case if the operation direction were, for example, in the direction of approaching and separating from the fulcrum, and the fulcrum of rotation is clearly fixed at the bottom of the palm. . Furthermore, the shape of the upper surface of the controller fits comfortably in the hand during operation, making it extremely easy for the player to use. Further, when the operation is stopped, the convex portion 115 can function as a palm rest.

Note that the arm 171.17''2 is not limited to a rod, but may be formed into a disk shape, for example.

3 and 4 show a second embodiment of the invention.

In this embodiment, straight grooves 31 and 32 are formed in place of the circular arc grooves in the above embodiment. This straight groove 31,
32 extends in the horizontal direction indicated by the arrow in the figure. knob 4
1.42 is directly connected to the axis of the sliding volume 51.52.

Therefore, the operators (knobs) 41 and 42 disposed in the operator arranging portion 30 of the operation panel 11 have approximately the circumference of a circle centered on the positioning recess 113, which serves as a fulcrum for the fingers during operation. It is arranged so that it can slide freely in the direction. The curvature in this case is considered to be infinite.

The other configurations and operations are the same as those of the above embodiment, and will therefore be omitted.

Note that this controller may be formed separately from the musical instrument as a controller unit, or may be formed by being fixed to the clasp part on the left side of the electronic keyboard instrument. There is no limitation, and the convex portion can also be used as a fulcrum.

<Effects of the Invention> As described above, according to the present invention, it is possible to obtain a musical tone control controller that allows quick and delicate operation of the operator without visually confirming the position of the operator.
