Description

Description: TECHNICAL FIELD The present invention relates to an expression foot switch device in an electronic musical instrument.

Configuration of Conventional Example and Problems Thereof FIG. 1 shows an example of a conventional assembly type electronic musical instrument generally used. In the figure, 1 is an organ body having a hand key board and various operation switches 2 and 3 is a stand. The organ main body 1 can be assembled with screws (not shown). A foot keyboard unit 4 is composed of a foot keyboard 5, an expression device 6 and an exterior cover 7, and is placed between the stands 3 and played.

FIG. 2 shows a conventional expression device.
An expression pedal 9 is rotatably mounted on the base 8 in the directions of arrows A and B, and the volume of the expression pedal 9 is controlled by rotating the expression pedal 9 with a foot during a performance. A foot pedal 10 is rotatably attached in the direction of the arrows C and D to the portion, and a foot switch (not shown) is operated by rotating the foot pedal 10 with a foot to operate the glide effect (the sound of the entire keyboard of the hand keyboard). It is configured to add a semitone lowering effect) and the like. However, the electronic musical instrument of the assembly type needs to be disassembled into the organ body 1, the stand 3 and the foot keyboard unit 4 so that it can be freely carried. In this case, in the conventional example, the foot pedal 10 of the foot keyboard unit 4 is used. Is protruding from the surface of the expression pedal 9,
Moreover, since it is made of sheet metal (see FIG. 2), the foot pedal 10 is easily deformed when it is applied to other objects, and the fingers and the like are easily injured. It had problems such as easy attachment.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and prevents the foot pedal from protruding beyond the surface of the expression pedal during transportation of the foot pedal to prevent deformation of the foot pedal, injury of fingers and the like. The purpose is to

To achieve the above object, an expression foot switch device of the present invention is provided with a foot lever for operating a foot switch and a foot pedal rotatably attached to the foot lever by a shaft. The foot lever is rotatably supported around an axis perpendicular to the side surface of the expression pedal between a state in which it projects from the surface of the expression pedal and a state in which it does not project. Further, according to the present invention, a foot lever for operating a foot switch and a foot pedal rotatably attached to the foot lever by a shaft are provided, and the foot pedal is attached to the foot foot lever around an axis parallel to a side surface of the expression pedal. Thus, the expression pedal is rotatably supported between a state where it projects from the surface of the expression pedal and a state where it does not project.

Description of Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the first embodiment shown in FIGS. 3 to 5 will be described.

In the figure, 11 is a foot lever for actuating a foot switch (not shown), which is mounted rotatably in the directions of arrows E and F as in the conventional example. 12 is a washer interposed between the foot pedal 13 and the foot lever 11, 14 is a screw shaft that pivotally supports the foot pedal 13 on the foot lever 11, and is a side portion of the expression pedal 15 in a direction perpendicular to the side surface of the expression pedal 15. The foot pedal 13 is rotatably attached with an appropriate tightening force. Reference numeral 16 is a locking piece formed integrally with the foot lever 11 and serves as a stopper so that the foot pedal 13 does not rotate more than necessary when standing up.

With the above-described structure, when the foot pedal 13 is rotated in the direction of arrow G from the state shown in FIG. 3, the state shown in FIG. 4 is obtained, and the foot pedal 13 does not project from the expression pedal 15. Next, in order to return the foot pedal 13 to the playing state, by rotating the foot pedal 13 from the state shown in FIG. 4 in the direction of arrow H, the foot pedal 13 rises up, and finally the engaging piece 16 engages. The rotation operation is stopped at the position where it is stopped, and the state shown in FIG. 3 is obtained.

As described above, according to the present embodiment, the foot pedal 13 and the foot lever 11 are supported by the shaft 14 provided at right angles to the side surface of the expression pedal 15, so that the foot pedal 13 has a plate thickness. It can be rotated in a direction parallel to and does not protrude from the surface of the expression pedal 15 during transportation.

Next, a second embodiment will be described with reference to FIGS. In the figure, the foot lever 11 is rounded in a pipe-like shape at one end thereof, and the foot pedal 13 is also rounded in the same manner as the foot lever 11 at one end portion on the foot lever 11 side. Reference numeral 17 is a shaft that pivotally supports the foot lever 11 and the foot pedal 13, and is oriented parallel to the side surface of the expression pedal 15, and is inserted into the pipe-shaped rounded holes of the foot pedal 13 and the foot lever 11. The pedal 13 is constructed so as to be rotatable with an appropriate turning force. Reference numeral 18 is a locking piece formed integrally with the foot pedal 13 and serves as a stopper so that the foot pedal 13 does not rotate more than necessary when standing up.

With the above-mentioned structure, when the foot pedal 13 is rotated in the direction of arrow I from the state shown in FIG. 7, the foot pedal 13 will turn into the expression pedal 15 as shown in FIG.
The expression pedal.
No longer sticks out from 15. Next, in the playing state, press the foot pedal 13
To return the foot pedal, move the foot pedal 13 from the position shown in FIG.
This foot pedal 13 rises up by turning in the direction, and finally the turning operation is stopped at the position where it is locked by the locking piece 18, and the state shown in FIG. 7 is obtained.

As described above, according to the second embodiment, the foot pedal 13 and the foot lever 11 are supported by the shaft 17 that is oriented parallel to the side surface of the expression pedal 15 so that the foot pedal 13 can overlap the upper surface of the expression pedal 15. The expression pedal 15 can be configured so as not to project from the surface of the expression pedal 15.

As described above, according to the present invention, the foot pedal is rotatably supported with respect to the foot lever around the shaft between a state in which it projects from the surface of the expression pedal and a state in which it does not project. In the playing state, the foot pedal can be turned up to perform a predetermined operation, and when carrying the foot keyboard unit, the foot pedal can be turned in the opposite direction to the playing state to allow the surface of the expression pedal to rotate. It can be prevented from protruding further. Therefore, when carrying the foot keyboard unit, the accident that the foot pedal hits another object and is deformed does not occur. In addition, the foot pedal does not injure fingers or the like, and when covered with a packaging material, the packaging material is not damaged and packaging becomes very easy.
