Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device for generating various control signals used when a musical tone such as an electronic musical instrument is generated.

[0002]

2. Description of the Related Art Conventionally, the most general type of operation device used in electronic musical instruments is a keyboard type device which controls sound generation by detecting the open / closed state of a key switch when a key is pressed. In addition, since the tone generation characteristic becomes monotonous with this alone, there is also one in which a touch response is detected in order to change the tone generation characteristic due to the difference in the pressing force at the time of key depression. Therefore, when an operator operates such a keyboard, a control signal corresponding to the pitch or volume is generated, and the electronic musical instrument generates a musical tone based on the control signal, thereby enabling the operator to operate the keyboard. It is possible to generate a suitable musical sound. In addition to this, there are wheel type and lever type operation devices for operating the modulation, pitch bend amount, and volume. Since these operating devices are configured such that part of the wheel or part of the lever protrudes from the upper part of the flat main body panel of the electronic musical instrument, the operator can rotate the wheel with fingers or operate the lever. The desired control signal is generated by tilting in one direction. In addition to this, there are also operating devices such as a foot switch and an expression pedal.

[0003]

However, since the conventional operating device outputs a control signal according to the operation amount of the fingers and feet, that is, the moving amount of the movable portion of the operating device, the vertical direction is centered on the movable portion. It was difficult to give a subtle modulation such as the finger vibrato playing method or the choking playing method of the guitar by moving it slightly.

The present invention has been made in view of the above points, and an object of the present invention is to provide an operating device capable of outputting a delicate modulated signal quickly.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing a configuration of an operating device according to the present invention, in which a part of a main body panel 1 of an electronic musical instrument or the like is extracted and shown. 1A is a view of a part of the operating device seen from the top surface of the panel, and FIG. 1B is a view showing a cross-sectional structure taken along the line AA of FIG. 1A. In this embodiment, the operating device is used for sounding and / or volume control of a guitar-like electronic claw instrument, and has a mode in which the operating device is operated while holding a fret switch (not shown). As shown in the figure, the operating device 4 has a wide bow-shaped main operating portion 50 corresponding to the vertical line of the letter "E" and wedge-shaped auxiliary operating portions 51 to 53 corresponding to the three horizontal lines of the letter "E". Consists of.
The operating device 4 has a shape that can be operated with one hand. The main operation section 50 can be operated anywhere with a palm or finger,
When the hand to be operated is the right hand, the auxiliary operation unit 51 is operated by the index finger, the auxiliary operation unit 52 is operated by the middle finger, and the auxiliary operation unit 53 is operated by the ring finger. That is, the operating device 4 operates the main operating part 50 with the base of the finger, and the auxiliary operating parts 51 to 53 with each finger.
Can be operated. Needless to say, the main operation section 50 may be operated with a fingertip. In order to project the main operation unit 50 and the auxiliary operation units 51 to 53 on the main body panel 1, the main operation unit 50 and the auxiliary operation units 51 to 5 are arranged.
It has an opening "E" -shaped opening 3 similar to the outer contour of FIG. The operation device 4 has a hinge structure that is rotatable around a shaft 59 as a rotation axis in a cut and raised portion 58 of a frame formed by cutting and raising the back plate 1B of the main body panel 1. That is, the operation device 4 is rotatable about a shaft 59 as a rotation axis, and is constantly protruded from the E-shaped opening 3 by a predetermined amount by a plate spring 56 provided inside the back plate 1B. It has become. A main operation part 50 and auxiliary operation parts 51 to 53 are provided at one end of this hinge structure.

The operating device 4 has a body panel 1 as shown in FIG.
From the E-shaped opening 3 provided on the front plate 1U of the main operation unit 50
And the auxiliary operation parts 51 to 53 are projected by a predetermined amount. In addition, the main operation unit 50 and the auxiliary operation units 51 to 5
The amount of protrusion from the surface of the body panel 1 with 3 is the body surface plate 1U.
Is defined by a stopper felt 57 provided on the. Further, the main operation part 50 has a flat shape, and the protrusion amount thereof is the same as a whole. The auxiliary operation parts 51 to 53 have a wedge shape when viewed from the upper surface of FIG.
The shape of the side view of (B) is configured to decrease according to the distance from the main operation unit 50. That is, the auxiliary operation parts 51 to 53 have the same protrusion amount as the main operation part 50 at the connection portion with the main operation part 50, and the protrusion amount gradually decreases at a predetermined inclination angle as the distance from the main operation part 50 increases, and the tip portion of the auxiliary operation parts 51 to 53 decreases. The height is the same as the surface of the panel 1, that is, the protrusion amount is zero.

The main operating portion 50 or the auxiliary operating portions 51 to 53 are adapted to rotate around the shaft 59 and sink into the main body panel 1 by receiving a pressing force from the operator's fingers. Main operation part 50 and auxiliary operation parts 51-53
The amount of sinking with and is defined by the stopper felt 5A provided on the back plate 1B. Since the shaft 59 is sufficiently separated from the main operating part 50 and the auxiliary operating parts 51 to 53, and the amount of depression (movable range) is relatively small, the main operating part 50 and the auxiliary operating parts 51 to 53 are It behaves as if it were sinking linearly. When the main operating portion 50 receives a pressing force, the value that allows the operating device 4 to rotate and move (the amount that can be depressed) is maximized and the main operating portion 50 is depressed into the main body panel 1 according to the magnitude of the pressing force. That is, the operator freely adjusts the pressing force applied to the main operating part 50 to freely set the sinking amount of the main operating part 50 and the auxiliary operating parts 51 to 53 within the movable range defined by the stopper felts 57 and 5A. Can be set selectively.
On the other hand, when any one of the auxiliary operation units 51 to 53 receives a pressing force, the amount of protrusion from the main body panel 1 at the position where the pressing force is received is maximized and the main body is adjusted according to the magnitude of the pressing force. Sink into the panel. That is, since the auxiliary operation parts 51 to 53 are wedge-shaped when viewed from the upper surface of FIG. 1A, when the user presses any part of the auxiliary operation parts 51 to 53 with a finger, the body panel 1 restricts the movement of the finger. Therefore, the amount of depression of the auxiliary operating portions 51 to 53 itself is also defined accordingly. The amount of depression of the auxiliary operating parts 51 to 53 varies depending on the position of pressing because the amount of protrusion of the auxiliary operating parts 51 to 53 is gradually decreasing. That is, as the pressed position moves away from the connection point with the main operation part 50, the amount of depression of the auxiliary operation parts 51 to 53 also gradually decreases. The magnet 5 is provided on the back side of the main operation unit 50 of the operation device 4.
4 is attached. A Hall element 55 is provided at a location of the body back plate 1B facing the magnet 54. The magnet 54 and the hall element 55 detect the rotational movement amount of the operating device 4.
The detection signal of the hall element 55 is output as a digital control signal by an A / D converter or the like.

Since the auxiliary operation parts 51 to 53 have such a shape, it is possible to realize an operation method in which the tip ends of the auxiliary operation parts 51 to 53 are traced toward the main operation part 50 with a finger. As a result, the control signal can be smoothly output. Further, by pressing a predetermined position of the auxiliary operation sections 51 to 53 with a finger, the amount of depression can be controlled with good reproducibility. That is, the operating device is the main operating unit 5
It is very difficult to reproduce the same amount of depression when it is only 0, but it is easy to reproduce the amount of depression by pressing the intermediate position of the auxiliary operation unit 52, for example.
Therefore, when it is desired to operate with the same amount of depression, it suffices to remember any part of the auxiliary operators 51 to 53 and press that part again, which makes the operation very easy. Further, by displacing the finger back and forth or / and right and left at the pressing positions of the auxiliary operation parts 51 to 53, it is possible to give the operating device 4 a vibration motion centering on the amount of depression. This can be applied as a musical tone control signal that gives a delicate modulation similar to a finger vibrato playing method or a choking playing method of a guitar.

In the above-described embodiment, the auxiliary operating portions 51 to 53 are formed so that the projecting amounts of the auxiliary operating portions 51 to 53 gradually decrease at a predetermined inclination angle as they move away from the main operating portion 50. As explained, the auxiliary operation unit 51
The amount of protrusion of ~ 53 may be the same amount, that is, may be constant.
Because the operating device 4 has a hinge structure, even if the depression amount due to the pressing operation is the same, as the pressing positions of the auxiliary operating portions 51 to 53 move away from the rotating shaft (shaft 59), that is, the rotating shaft. This is because the distance between the magnet 54 and the Hall element 55 gradually changes depending on the relative distance between the pressing position and. Further, in the above-described embodiment, the case where the operating device 4 has the hinge structure has been described, but the main operating portion 50 and the auxiliary operating portions 51 to 53 are provided in the main body panel 1 generally in parallel like a push button switch. It may have a structure that sinks. However, in this case, the amount of protrusion of the auxiliary operation parts 51 to 53 must be gradually reduced.

In the above-mentioned embodiment, the auxiliary operation parts 51 to 51
The configuration in which the amount of protrusion of 53 is gradually reduced with a predetermined inclination angle has been described, but the present invention is not limited to this, and a configuration in which the amount of protrusion is reduced stepwise may be used. Needless to say, it may be provided. Further, in order to make the pressed position easy to understand, a display (for example, a scale) may be provided as a guide on the main body panel 1. Furthermore, the size of the inclination angles of the plurality of auxiliary operation portions may be different, or the inclination angles may be the same and the protrusion amounts of the tip portions of the auxiliary operation portions 51 to 53 may be different. Alternatively, both the angle of inclination and the amount of protrusion of the tip may be different. In this way, by making the inclination angles of the respective auxiliary operating elements 51 to 53 different and the projecting amounts of the distal end portions thereof, the lengths in the longitudinal direction of the plurality of auxiliary operating portions can be apparently increased.
That is, the inclination angles of the three auxiliary operating portions 51 to 53 are the same, and the respective auxiliary operating portions 51 when not pressed.
It is possible to operate as an auxiliary operation unit having a length of three by using three short auxiliary operation units by making the protruding amounts of the leading end portions to 53 different from each other so that all the protrusion amounts are not the same. . In the embodiment described above, FIG.
Although the case where the auxiliary operating portions 51 to 53 have a wedge shape as shown in (A) has been described, the auxiliary operating portions 51 to 53 may have a rectangular shape or a trapezoidal shape. Further, in the drawing, the outer shapes of the main operating part 50 and the auxiliary operating parts 51 to 53 are shown as having roundness as a whole, but they may be angular.
Further, the shapes of the projecting portions of the main operating portion 50 and the auxiliary operating portions 51 to 53 may be rounded like a semi-cylindrical shape or may be angular. Further, in the above-described embodiment, the case where the number of the auxiliary operation units 51 to 53 is three has been described, but it goes without saying that the number may be smaller or larger than this. In addition, since there are a plurality of auxiliary operation portions, the finger to be pressed can be changed without changing the operation state, and rapid continuous hitting becomes possible. Further, although the case where the operating device is operated by hand has been described, the operating device may have a shape that can be operated by the foot. Further, in the above-described embodiment, the sensor including the magnet 54 and the hall element 55 is used to detect the rotational movement amount of the operating device 4, but the present invention is not limited to this, and the operating amount of the operating device 4 is not limited to this. Any sensor may be used as long as it can detect it. For example, a reflecting plate may be provided instead of the magnet, and the moving amount of the reflecting plate may be detected by using an optical element, or the rotational moving amount of the operating device 4 may be directly detected by a rotary transformer, an encoder, or the like. . The main operation part 50 and the auxiliary operation parts 51 to 53 may be arranged in reverse, that is, the main operation part may be arranged farther from the rotation axis than the auxiliary operation part. In this case, its function is reversed,
The main operation parts are 51 to 53.
