Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard device that can be used in electronic keyboard musical instruments and the like, and a keyboard weight position setting means used in this keyboard device.

[0002]

2. Description of the Related Art A keyboard device for an electronic keyboard instrument has a drawback that it is difficult to obtain a feeling of tapping like a piano because it only operates a switch for controlling generation and stop of sound. For this reason, conventionally, as shown in FIG. 11, a weight 3 supported by a shaft 2 is provided corresponding to each key 1 in a state capable of seesaw movement, and a non-weight portion 4 opposite to the weight 3 is projected from each key 1. Engage the protrusions 5 and use the weight 3 to load the key 1
A structure that gives a feeling of keystroke by giving a reaction force to is practically used.

[0003]

According to the structure of the keyboard weight 3 shown in FIG. 11, the engagement position between the key 1 and the non-weight part 4 (the constant position of the keystroke stroke of the key 1) is constant. Therefore, there is a drawback that the feeling of hitting the key 1 cannot be freely changed. SUMMARY OF THE INVENTION An object of the present invention is to provide a keyboard device which can freely change the feeling of hitting the keyboard and a keyboard weight position setting means used in this device.

[0004]

According to the present invention, the keyboard device is provided so as to face each key in a state capable of seesaw movement, and the end of the non-weight portion engages with each key, and the weight is applied to the keystroke. In the keyboard device that is structured to give a reaction force by the load of
The present invention is characterized in that a keyboard weight position setting means capable of setting the rotation angle position of the weight to an arbitrary position is provided, and the engagement start point with the weight can be arbitrarily set within the keystroke stroke of each key. To do.

According to the keyboard device of the present invention, the engagement start point with the weight can be set at an arbitrary position within the keystroke stroke of each key, so that the feel of a heavy touch to that of a light touch can be freely set. Can be set and changed.
Therefore, there is an advantage that it is possible to set a keystroke feeling that matches the taste of the player.

1 to 3 show an embodiment of the present invention.
Portions corresponding to those in FIG. 11 are designated by the same reference numerals. In the figure, 1 is a key, 2 is a shaft that supports a weight 3 in a seesaw movable manner, 4
Is a non-weight portion that is projected to the opposite side of the weight 3, and 5 is a protrusion that is provided on the back side of each key 1. The non-weight portion 4 is engaged with the lower end of the projection 5 to give a feeling of tapping, but in the present invention, a structure is provided with keyboard weight position setting means 10 for arbitrarily setting the rotation angle position of the weight 3. It is characterized by.

In the example shown in FIGS. 1 to 3, the lifter 11 is arranged below the weight 3 in the arrangement direction of the weight 3, and the main part of the lifter 11 In this example, as shown in FIG.
Screw shafts 12 are provided so as to project downward at three positions, that is, both ends and an intermediate portion of 1, and the screw shafts 12 are engaged with screw holes formed in the center of the gear 13. Teeth 13A are formed on the outer peripheral surface of the gear 13, and another gear 14 meshes with the tooth 13A. The gear 13 is rotationally driven by the gear 14 to move the lifter 11 in the vertical direction.

That is, the gear 13 has a recess bearing on both the upper surface side and the lower surface side, and the cylindrical bearing 15 is engaged with the recess bearing to be rotatably supported. A screw hole is formed at the center, and the screw shaft 12 is screwed into this screw hole. Therefore, by rotating the gear 13 via the gear 14, the screw shaft 12 can be moved up and down. By moving the screw shaft 12 up and down, the shifter 11 moves up and down, and the turning position of the weight 3 can be moved.

In this example, the gear 14 is rotationally driven by a bevel gear 17 mounted on a rotary shaft 16 which extends across almost the entire width of the keyboard as shown in FIG. Rotating shaft 16
A motor 19 is connected to the end of the lifter 11 via a gear reduction mechanism 18, and is driven in the forward and reverse directions by the motor 19 to set the position of the lifter 11 to an arbitrary position. Thereby, the rotation angle position of the weight 3 can be set to an arbitrary position.
By setting the rotation angle position of the weight 3 to an arbitrary position, the engagement start point with the protrusion 5 protruding from the key 1 can be appropriately changed. As a result, various settings can be made whether the reaction force received from the weight 3 when hitting each key 1 is received from the beginning of the keystroke or when the keystroke is finished.

4 to 6 show another embodiment of the keyboard weight position setting means 10 of the present invention. In this example, a flap 20 that rotates in the same direction as the rotation direction of the weight 3 is provided below the weight 3, and the rotation position of this flap 20 is set to a lever 21.
Keyboard weight position setting means 1 by adjusting by
The case where 0 is configured is shown. FIG. 5 shows the lever 21 with the motor 1
9 shows a case of a structure in which the screw feeding mechanism 22 is used for operation. Further, FIG. 6 shows a case where a fan-shaped worm wheel 23 is attached to the flap 20, a worm 24 is meshed with the worm wheel 23, and the worm 24 is rotated by a motor 19 to constitute the keyboard weight position setting means 10.

7 to 10 show still another embodiment of the present invention. In this embodiment, rails 25 are provided below the weights 3 in the arrangement direction of the weights 3, and the rails 25 and the board 26 are provided.
The hinge 27 is inserted between the and, and the rail 25 is moved by moving the rail 25 in the arrangement direction of the weight 3, and the rail 25 is moved up and down by the rotation of the hinge 27. The case where the setting means 10 is configured is shown. Incidentally, reference numeral 28 in the drawing denotes a stopper for restricting the rotation range of the hinge 27.

In the example of FIG. 7, the rail 2 is moved by the lever 29.
The case where 5 is moved is shown. FIG. 8 shows a case where the rail 25 is moved by the electromagnetic solenoid 30. In the embodiment of FIG. 8, the set positions are two positions.
In the example of FIG. 9, the gear 32 is rotated by the handle 31, the feed screw 33 screwed into the screw hole of the gear 32 is screw-fed in the axial direction, and the rail 25 is connected to the feed screw 33. Indicate the case. FIG. 10 shows a case where the motor 19 is used instead of the handle 31 shown in FIG.

[0013]

As described above, according to the present invention, the weight 3 supported so as to be capable of seesaw movement corresponding to each key 1 of the keyboard musical instrument is prepared, and the weight 3 can be vertically moved below the weight 3. The lifter 11, the flap 21, or the rail 25 is provided, and the lifter 11, the flap 21, and the rail 25 are provided.
Thus, the turning position of the weight 3 can be set to an arbitrary position. Therefore, the engagement start position of each key 1 and the weight 3 can be freely selected and set within the keystroke stroke of each key 1. Therefore, it is possible to freely select from a heavy touch feeling to a light touch feeling. Can be set.

Therefore, according to the present invention, the feeling of tapping can be set in accordance with the taste of the player, so that there is a practical advantage that an optimal performance can be performed.
