Further, an angle sensor is provided and the angle of the rotation is detected to output the pitch of the pitch variation curve.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operator device for an electronic musical instrument, which is provided with an operator for controlling a musical tone called a pitch bender, which imparts a musical effect to a musical tone.

[0002]

2. Description of the Related Art A pitch bender raises or lowers the pitch of a musical tone of an electronic musical instrument by changing the resistance value of a variable resistor according to the rotation of an operating element, thereby obtaining a playing effect. Conventionally, a pitch bender shown in FIG. 14 has been proposed (see Japanese Utility Model Laid-Open No. 58-69905).

The operating device 49 of the electronic musical instrument includes a lever 41a for rotating a variable resistor (not shown) and a response to the rotation of the operating device 41, and when the lever 41a is released. A torsion coil spring 45 is provided for returning the lever to the initial position. Further, by performing A / D conversion of the analog voltage from the variable resistor, it is possible to arbitrarily set the pitch change curve so that the amount of change in the pitch of the musical sound of the electronic musical instrument to be raised and lowered differs depending on the lever rotation region. A technique has also been proposed (see Japanese Patent Laid-Open No. 2-296296). For example, when a pitch change curve as shown in FIG. 15 is set, turning the lever to the upper end side enables a performance imitating the choking performance of an electric guitar,
When turned to the lower end side, a performance imitating the arm-down performance of the electric guitar tremolo arm becomes possible.

[0004]

In the technique for A / D converting the analog voltage from the conventional variable resistor described above, when different pitch change curves are set in the small turning area and the large turning area of the operator. In addition, even if the control element moves to a different pitch change curve area, it is difficult for the performer to immediately recognize that it has changed to a different pitch change curve area. It is difficult to operate the child to add a playing effect,
Therefore, there is a problem that the performance becomes jerky.

In view of the above circumstances, it is an object of the present invention to provide an operator device for an electronic musical instrument that allows a player to immediately recognize that the operator has moved to a region of a different pitch change curve.

[0006]

In order to achieve the above object, a first electronic musical instrument operating device of the present invention is pivotally mounted on a main body and is tiltable in both directions. An operator that rotates with respect to the main body, a first urging force applying unit that applies an urging force against the rotation of the operator, and a first operator when the operator rotates a predetermined amount or more. In addition to the urging force applying means, the second urging force applying means for applying an urging force, and an angle sensor for detecting an angle of rotation of the operator are provided.

In addition, an operator device for an electronic musical instrument according to a second aspect of the present invention for achieving the above object is pivotally attached to a main body portion, can be tilted in both directions, and can be rotated with respect to the main body portion by tilting. A moving operator, a first biasing force applying means for applying a biasing force against the rotation of the operator, an angle sensor for detecting the angle of rotation of the operator, and the operator rotating by a predetermined angle. In this case, the operating element abuts and is pressed, and a pressure-sensitive element that detects the pressing force by this pressing is provided.

Here, it is preferable that the operating element is provided with an arm member that abuts the pressure-sensitive element and elastically deforms when the operating element rotates by a predetermined angle. Further, a third electronic musical instrument operator device of the present invention for achieving the above object is
A manipulator that is pivotally attached to the main body, is tiltable in both directions, and that is tilted to rotate with respect to the main body, and a first attachment that applies a biasing force against the rotation of the manipulator. Boundary between the force applying means, the angle sensor that detects the angle of rotation of the operator, the first operation area within a predetermined rotation amount of the operator, and the second operation area that exceeds the predetermined rotation amount. And a click feeling imparting means for imparting a click feeling to the operation of the manipulator when passing through.

[0009]

In the first operating element device of the present invention, when the operating element is rotated by a predetermined amount or more, the second urging force applying means operates in addition to the first urging force applying means. Therefore, when the operator is operated within a range of a predetermined rotation amount or less, only the first biasing force applying means acts, while when the operator is operated over a predetermined rotation amount, the first biasing force is applied. In addition to the biasing force of the imparting means, the biasing force of the second biasing force imparting means is transmitted to the player as a response, and therefore, the response is changed when the player operates the predetermined rotation amount, and thereby the operation within the predetermined rotation amount is performed. The player immediately recognizes that the pitch change curve is different from the time. When the operation element is operated beyond the predetermined rotation amount, it is detected by an angle sensor that detects the rotation angle of the operation element, and the pitch is changed to a pitch change curve whose pitch is different from that during operation within the predetermined rotation amount. To be done.

Further, although the first manipulator device is configured to rotate beyond a predetermined amount of rotation, in the second manipulator device of the present invention, the manipulator has a predetermined angle. When turned, this operator turns only slightly further,
Alternatively, it is provided with a pressure-sensitive element which hardly rotates but instead abuts and is pressed. Therefore, when the operator is operated by a predetermined amount of rotation, the response is transmitted to the player. When the operator is operated by the predetermined amount of rotation and a force is further applied in the rotation direction, this force is detected by the pressure sensitive element, and the pitch can be changed according to the magnitude of the force. If the operator is provided with an arm member that comes into contact with the pressure-sensitive element and elastically deforms when the operator rotates a predetermined angle, the operator cannot rotate even after the arm member comes into contact with the pressure-sensitive element. This rotation allows the player to easily adjust the force applied to the pressure-sensitive element.

Further, in the third manipulator device, the manipulator is operated when the manipulator passes through the boundary between the first operation area within a predetermined rotation amount and the second operation area exceeding the predetermined rotation amount. Since the player is provided with a click feeling imparting means for imparting a click feeling to the child's operation, the player recognizes that the transition to a different pitch change curve region is caused by the click feeling when passing through the boundary.

1 (a) is a front view of a first embodiment of an operator device for an electronic musical instrument according to the present invention, and FIG. 1 (b) is FIG. 1 (a).
FIG. The operator device 9 of the electronic musical instrument of this embodiment is roughly composed of a main body 3 and an operator 1. The manipulator 1 is mounted on a shaft 3a extending from the main body 3. A first torsion coil spring 5 and a second torsion coil spring 7 are wound around the rotary shaft of the operator 1. Both ends 5a, 5b of the first torsion coil spring 5 are held at predetermined intervals by a holding member 3b extending from the main body portion 3, and both ends of the second torsion coil spring 7 are held by a holding member 3c extending from the main body portion 3. It is held so as to spread from both ends of one torsion coil spring 5. In addition, the operating element 1 extends between both ends of the torsion coil springs 5 and 7, and when the operating element is rotated, each end is moved against the bias of the torsion coil springs 5 and 7. The moving member 1b is provided. 2 (a) is shown in FIG.
2A is a front view showing a state in which the lever 1a of the operator 1 is operated and the operator 1 is rotated counterclockwise in FIG.
FIG. 2B is a front view showing a state where the manipulator 1 is further rotated as compared with FIG. Further, FIG. 3 is a diagram showing an example of a pitch change curve with respect to an operation amount of an operator.

As shown in FIG. 2A, as the operator 1 rotates, the rotating member 1b resists the one end 5a of the first torsion coil spring 5 against the urging force of the first torsion coil spring 5. The player feels that the operating element is rotated by this urging force. An angle sensor (not shown) such as a rotary knob detects the angle of rotation of the manipulator 1, whereby the pitch change curve corresponding to the angle of rotation, that is, the first region shown in FIG. The pitch based on the pitch change curve of is output.

When the operator 1 is further rotated, FIG.
As shown in (b), the rotating member 1b moves one end 7a of the second torsion coil spring in addition to the one end 5a of the first torsion coil spring. As a result, the biasing force of the second torsion coil spring 7 is added to the biasing force of the first torsion coil spring 5, and due to the increase of this biasing force, the performer 1
It is possible to immediately recognize that the rotation of has shifted to the area of the different pitch change curve (second area shown in FIG. 3). In addition, the angle of rotation is detected by the angle sensor, and the pitch change curve different from the state of FIG. 2A, that is, the pitch change curve of the second region shown in FIG. The pitch based on is output.

FIG. 4 (a) is a front view of a second embodiment of the operator device for an electronic musical instrument of the present invention, and FIG. 4 (b) is FIG.
It is an AA sectional view of (a). The operating device device 19 of the electronic musical instrument of this embodiment is roughly composed of a main body 13, an operating device 11, and an abutting member 12. The manipulator 11 is
It is attached to a shaft 13a extending from the main body portion 13, and a torsion coil spring 15 is wound around the rotary shaft of the operator 11. Both ends 15a, 1 of this torsion coil spring 15
5b is held by a holding member 13b extending from the main body 13 so as to keep a predetermined distance, and a rotating member 11b fixed to the operator 11 extends between both ends of the torsion coil spring 15. A contact member 12 with which the operator comes into contact when the operator 11 is rotated by a predetermined amount of rotation extends from the main body 13 along the shaft 13a, and the pressure-sensitive element 16 is provided on the contact surface. It is provided.

5 (a) is a front view showing a state in which the lever 11a of the operating element 11 of FIG. 4 is operated and the operating element 11 is rotated counterclockwise in FIG. 5 (a), FIG. 5 (b). Is shown in FIG.
It is a front view which shows a mode that the operation element 11 rotated further counterclockwise from (a), and the operation element 11 contacted the pressure sensitive element 16. FIG. 6 is a diagram showing an example of a pitch change curve with respect to the operation amount of the operator shown in FIG.

Along with the rotation of the operator 11, the rotating member 11
b moves one end 15a of the torsion coil spring 15 against the urging of the torsion coil spring 15, and the urge allows the player to feel the response that the operating element 11 has been rotated. When the button is released, the operator 11 returns to the original state. Further, an angle sensor (not shown) detects the rotation angle of the manipulator 11, and based on the pitch change curve corresponding to this rotation angle, that is, the pitch change curve of the first region shown in FIG. Output pitch is output.

When the operator 11 is further rotated from the state shown in FIG. 5 (a), the operator 11 is moved as shown in FIG. 5 (b).
Comes into contact with the pressure-sensitive element 16 and becomes a state in which it can rotate only a little more. The performer can feel this in response. The pressure-sensitive element 16 is pressed within a range in which it can rotate after the contact, and this pressing force is detected by the pressure-sensitive element 16, and based on the pitch change curve of the second region shown in FIG. Determines whether to raise or lower the pitch, and outputs the pitch.

FIG. 7 (a) is a front view showing a state in which the operator 11 is rotated counterclockwise in FIG. 7 (a) in the third embodiment of the operator device for an electronic musical instrument of the present invention. 7 (b) is
FIG. 8 is a front view showing a state where the manipulator 11 further rotates counterclockwise from FIG. 7A, and an arm member provided on the manipulator 11 abuts the pressure-sensitive element 16 and is elastically deformed. The manipulator 11 shown in FIG. 7 is the manipulator 11 shown in FIG. 4 provided with two arm members 11c. This arm member 11
When the manipulator 11 is rotated and comes into contact with the pressure sensitive element 16, elastic deformation occurs in c, and the player can feel this elastic deformation as a response. Further, due to the elastic deformation of the arm member 11c, the manipulator 11 can be rotated even after the arm member 11c is in contact with the pressure-sensitive element 16, and thus the player presses the pressure-sensitive element 16. Control of pressing force becomes easy. Therefore, even if the pitch changes abruptly like the pitch change curve of the second region shown in FIG. 6, the control becomes easy.

FIG. 8 is a flow chart for generating the pitch change curve shown in FIG. 6 from the operation amount of the operator shown in FIGS. In step 101, each voltage output from an angle sensor (not shown) and the pressure-sensitive element 16 is A / D converted by rotating the operating element 11 and pressing the pressure-sensitive element 16, so that each voltage becomes 0. To an integer value of 127. Here, the voltage output from the angle sensor becomes 0 when the operator 11 is fully tilted to one side,
It is A / D converted so that it becomes 127 when it is pushed down to the other side. Further, the voltage of the pressure sensitive element 16 becomes 0 when it is not pressed and 1 when it is pressed sufficiently strongly.
27. These A / D converted values are C
Stored in separate registers in PU (step 10)
2). Next, in step 103, the value output from the angle sensor is set to 0 at the midpoint where the manipulator 11 is not rotated.
Offset processing is performed so that Thereby, the value output from the angle sensor becomes a negative value when the operator 11 is tilted to one side and a positive value when the operator 11 is tilted to the other side. In addition, in step 103, dead zone processing is performed to obtain a region in which the pitch is not changed in the vicinity of the midpoint so that the pitch is not changed only by the player touching the operator 11. Next, in step 104, it is checked whether the value of the angle sensor after performing the offset process as described above is positive or negative. This is because it is necessary to know the direction of rotation of the manipulator 11 in order to set a pitch change curve that differs depending on the direction of rotation of the manipulator 11 (see FIG. 6). In steps 105 and 106, the pitch change amount is determined based on the pitch change curve corresponding to the direction of rotation. Here, the pressure-sensitive element 16 requires a predetermined return time to return to its original state once pressed, and during that time, a residual voltage that is still pressed is output from the pressure-sensitive element 16. Therefore, in step 107, in order to prevent the return time and the residual voltage from adversely affecting the change in pitch, for example, when the output from the angle sensor is equal to or less than a predetermined value, the output from the pressure sensitive element 16 is ignored. Is processed. Then, in step 108, the pitch of the musical tone is determined, and in step 109, the musical tone is emitted. Then, the process returns to step 101 and the same procedure is repeated.
