BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upright device for a undulating musical score plate provided in a keyboard instrument or the like.

[0002]

2. Description of the Related Art For example, there is a musical score plate of a piano that uses the inside of a keyboard lid, but there is also a musical instrument that is attached to the upper surface of the musical instrument, and in that case, from the state of standing up above the musical instrument, It is usually placed on the mounting surface so that it does not get in the way when not in use.

The conventional music plate such as the latter has a structure in which, for example, the music plate is hinged to the mounting surface, and a stopper provided behind it supports the mounting surface, or a recessed hole is formed in the mounting surface. The structure is such that a fitting protrusion provided at the lower end of the music plate is fitted and raised.

However, although the structure in which the stopper supports the mounting surface is simple, there is a problem that the stopper tends to fall down, and particularly when the score is large or heavy, it becomes extremely unstable.
The one provided with the protrusion also has a problem in strength, and also has a problem of where to put the removed one.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points. The problem is that the musical score can be supported sufficiently stably when it is used, and it can be folded flat when not in use. It is possible to make a music plate that can be undulated, and especially to make it easy to raise the music plate when using it.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a musical score plate 1 is attached to a mounting portion 2 at one end thereof by a support shaft 3 so as to be rotatable. 1 is formed so that it can be undulated, and a stopper 4 for supporting the music plate 1 is attached at one end to a mounting portion 2 located on the back side of the music plate 1 in the rotational direction by a support shaft 5 so as to be rotatable. 4 is set to a length exceeding the axial fulcrum of the musical score plate 1 and supports the musical score plate 1 in a standing posture of the musical score plate 1. Therefore, a locking portion 6 engageable with the musical score plate 1 on the back side is attached to the stopper 4. A means for providing a musical score stopper 7 for supporting the lower end of the musical score leaning against the musical score plate 1 is provided at a portion of the stopper 4 on the tip side of the engaging portion 6.

The musical score plate 1 is made of a thin flat plate-like member, and is rotatably attached to a mounting portion 2 formed of a horizontal surface at one end portion, that is, a lower side portion thereof by a spindle 3. It is formed so that it can rise and fall in contact with the mounting portion 2 from the lying position (solid line in FIG. 1) to the standing upright posture (solid line in FIG. 2). The hinge 3 used for the opening and closing part of a keyboard instrument can be used for the support shaft 3.

The stopper 4 is rotatably attached by a support shaft 5 to an attachment portion 2 located on the back side of the musical score plate 1 in the rotational direction. The stopper has a length exceeding the pivotal fulcrum of the music plate 1, and therefore can be inverted from the position on the back side of the music plate 1 in contact with the plate surface of the mounting portion 2 to the position on the front surface of the music plate 1. .

The stoppers 4 are located on the back side, that is, behind the support shaft 3 as described above with reference to the rotating direction of the musical score plate 1, but in the embodiment, they are arranged on both left and right sides of the musical score plate 1. The left and right sides 8 of the music score plate 1 are supported respectively. The support shaft 5 is fixed to the mounting portion 2 using a mounting bracket 9.

The locking portion 6 is provided so as to project from the midway portion of the stopper 4 toward the center of the music plate so that it can be locked on the back side of the side 8 to support the music plate 1 in the upright posture. ing.

The music score stopper 7 is attached to a portion closer to the tip than the locking portion 6 described above, protrudes upward in the front of the music score plate 1 and supports the lower end of the music score.

For this reason, the stopper 4 has the shape of an elongated U-shaped frame in which a music score stopper 7 is attached to the ends of a pair of left and right members. Therefore, the pair of left and right stoppers 4 and 4 are the music stoppers 7.
The music stopper 1 can be moved while holding the music scoreboard 1 (FIG. 1), and the music score stopper 7 overlaps the music scoreboard 1.

When the musical score stopper 7 is pulled up and rotated counterclockwise in FIG. 1, the musical score plate 1 engaged with the engaging portion 6 of the stopper 4 at its side is raised to support the musical score plate 1. When the music score stopper 7 is rotated in the same direction about the shaft 3 and the music score stopper 7 is inverted about the support shaft 5 to come closest to the mounting portion 2, the music score plate 1
Is also erected and is supported by the locking portion 6 (FIG. 2). The musical score is supported at its lower end by the musical score stopper 7, the back is supported by the musical score plate 1, and the load of the musical score plate 1 is applied so as to press the stopper 4, so that it is in a stable use state.

Such a device of the present invention can be attached to a keyboard musical instrument, and since it has a structure capable of undulating, it can be compactly housed even when the upper part of the keyboard is not so high in structure as in an electronic organ.

An example in which the device of the present invention is attached to a keyboard instrument will be described below with reference to FIGS.

The mounting portion 2 is a top plate of the musical instrument body 20, specifically, an inner portion of the front top plate 21. Front top plate 21
A first vertical plate 22 that covers the step to the keyboard part 25 is provided at the front edge of the keyboard, a lid part 23 that covers the upper surface of the keyboard part is provided at the lower edge, and the front edge covers the front surface of the keyboard part. Second vertical plate 2
4 is provided, the lid portion 23 can be inverted 180 degrees by the shaft portion 26, and the second vertical plate 24 is also rotated 90 degrees by the shaft portion 27 so as to be superposed on the inner surface of the lid portion 23.

Since the front top plate 21 is attached to the front edge of the rear top plate 28 by the shaft 29 so as to be able to be inverted by 180 degrees, the device of the present invention is accommodated in the upper part of the musical instrument body 20 (FIG. 4). In this state, the shaft portion is tightened so as not to go down into the instrument body, or is held in a constant posture by holding means 31 as shown in FIGS. 1 and 4, for example. Therefore, the front top plate 21 is turned upside down on the rear top plate around the shaft 29 (FIG. 5), and when the music stopper 7 is pulled up, the music stand is set to the normal state (FIGS. 5 and 6). .

When the musical score plate 1 is erected and the lid portion 23 is further inverted, the front edge 23 'can be set so as to contact the back surface of the musical score plate 1, so that the musical score of the musical score plate 1 can be set. The support structure is further strengthened. FIG. 6 shows the same situation as FIG. 2 in the previously described embodiment.

On the other hand, when the musical score plate 1 does not need to be erected and another keyboard 30 or the like is used together with the keyboard instrument, the lid 23 serves as a mounting table for the keyboard 30 (FIG. 7).

As described above, the device of the present invention is suitable as a music stand of a keyboard instrument having a small upper structure and a small dimensional margin. However, it is not limited to keyboard instruments or keyboard devices,
It can be incorporated into various objects such as a case of a musical instrument.

[0022]

[Effects of the Invention] Therefore, according to the present invention, it is possible to support the musical score sufficiently stably when it is used and to fold it up flat when not in use.
Since the stopper 4 has a structure that can be engaged with the music scoreboard 1, the music scoreboard 1 can be stood up by an operation of pulling up the stopper 4 and the music scoreboard 1 can be easily erected. Also, since it becomes flat as described above when not in use, any musical instrument, frame, case or other portion can be selected as the mounting portion 2. Especially when it is mounted on a keyboard musical instrument, the occupied portion is very small, so the musical instrument side It has a remarkable effect that it does not need to be changed.
