Parts 52 are superimposed, and furthermore, their common mounting parts 52
The common mounting part 52 of the black key unit 21 is superimposed on
These seven white keys 33-36, 43-45 and 5
One octave (predetermined key)
Keyboard unit 60 (FIG. 4 and FIG. 4).
(See FIG. 5). Here, a one-octave keyboard unit 60
Are provided with seven white keys 33 to 36, 43 to 45
The first white key unit 31 and the second white key unit 41
Is positioned by the first positioning means 61.
You. Also, this one-octave keyboard unit 60 and this
One octave keyboard unit on the lower or higher frequency side
Means a predetermined position such as a key arrangement direction by the second positioning means 71.
Has been positioned. That is, the first positioning means 61
As shown in FIG. 2, the common mounting portion of the first white key unit 31
52 at a substantially central portion in the length direction (key arrangement direction).
Hole 63 and common mounting portion 52 of second white key unit 41
Fits into the hole 63 at the approximate center of the length direction (key arrangement direction)
The projection 65 is formed so as to protrude downward so as to be inserted.
You. In other words, the first white key unit 31 and the
2 octaves combined with 2 white key units 41
When forming the keyboard unit 60, these white key units
First positioning means 61 for positioning between 31 and 41
Is the position of the E key 34 of these white key units 31 and 41
And the common mounting portion 52 at the position of the F key 44.
You. Further, the common mounting of the first white key unit 31
The upper surface of the portion 52 bulges upward in a rectangular shape, and the second white key unit
The common mounting portion 52 of the knit 41 is also rectangular in accordance with this shape.
Is formed. This rectangular bulge is a rectangular recess
And the positioning of the common mounting portion 52 in the width direction in particular.
What to do. The common mounting portion 52 of the black key unit 21
And the common mounting portion 52 of the second white key unit 41.
A hole 81 having the same structure as a positioning means therebetween.
And a projection 83 are formed respectively. These holes 8
1 and the projection 83 are respectively located on the common mounting portion 52,
It is located in the middle of its length direction (key array direction).
You. A hole 81 is formed in the common mounting portion 52 at the position of the F key 44 by a projection.
83 is a common mounting part 52 at the position of the F key 25,
It is arranged. In addition, these common mounting portions 5
2 in that a dent of the same shape as the rectangular bulge is formed
Has a similar configuration. The one-octave keyboard unit 60 is
Keyboard that spans multiple octaves
, The keyboard unit 60 of each octave
Positioning between them is required. The second that makes this positioning
The positioning means 71 is a common unit of the first white key unit 31.
A first position is provided at both ends in the longitudinal direction (key arrangement direction) of the attaching portion 52.
A hole 73 having the same configuration as the positioning means 61 and fitted into the hole 73
Are formed by forming the projections 75 respectively.
Have been. The second positioning means 71 is one octave.
Key of the common mounting portion 52 of the keyboard unit 60 constituting the
That is, they are arranged at the ends in the arrangement direction. Figure 3
Of the second positioning means 71 is shown in cross section. In addition, the above three units, which are resin molded products,
, 31, and 41 are long at their common mounting portion 52.
Three slots 84, 85, 86 are equally spaced at the same position in the hand direction
It is formed in the septum. These slots 84, 85, 86
Shows that the screw 90 is inserted as shown in FIG.
The entire unit assembly is mounted on a resin frame 91 as a whole.
It can be attached. Note that, as shown in FIG.
The horizontal projection 93 formed on the common mounting portion 52 of each key fits
An insertion hole 95 to be inserted is formed. According to the above configuration
Keyboard unit, a one-octave keyboard unit 6
0 is assembled to the frame 91. In this case, whether it is on the first white key unit 31 or not.
And align the second white key unit 41
You. The positioning at this time is performed by the first positioning means 61.
The protrusion 65 is fitted into a certain hole 63, and the bulging portion is recessed.
It is done by fitting only. As a result, the seven white keys 33 to 36,
43-45 are assembled in an array as shown in FIG.
A predetermined gap between the key 34 and the F key 44 (equal intervals in the longitudinal direction)
It is beautifully assembled with. Next, the black key unit 21 is connected to the second white key unit.
The knit 41 is overlaid from above. Location of both units
In the same manner as above, the protrusion 83 is fitted into the hole 81 and swelled.
This is achieved by fitting the part and the recess. This
In this way, a set of one octave keyboard unit 60 is formed.
After the completion of the setting, as shown in FIG.
Assemble the whole. The screw 90 shown in FIG.
And stick them together. The frame 91 has a plurality of octaves.
Arrange a plurality of keyboard units 60 to form a keyboard
If you want to play the
The positioning between the knits 60 is performed by the second positioning means 71.
This is done. That is, as shown in FIG.
First white key unit for the keyboard unit 60 of the keyboard
The hole 7 formed in the common mounting portion 52 at the position of the B key 36 of 31
The keyboard unit that constitutes the higher octave
The C key 33 of the first white key unit 31
The projection 75 protruding from the lower surface of the common mounting portion 52 is fitted at the position
The positioning is performed by the insertion. As described above, a plurality of frames
A keyboard device with octave keys 33 is extremely simple
Assembled. In this case, the positioning means 61, 71
Is the position where the deviation and error etc. are smallest in the resin molded product
Approximately the center of the common mounting portion of each unit in the key array direction
The white key 3 even after assembly
3, 36 (34, 44) in the adjacent part
The difference is small and can be assembled beautifully as an external appearance
You. Each key of the keyboard device has a key body.
When the part 50 is pressed, the first hinge part 56 of the fulcrum part 54 is
Deflected up and down, with the common mounting part 52 as a fulcrum as a whole
Swing up and down. Then, a predetermined portion of the frame 91
By turning on the switch attached to the
Will occur. The seven keys that make up the one-octave keyboard
Of the F key 44, the A key 45, the C key 33, and the E key 34
First white key unit integrated with G key 35, B key 3
6, 2 minutes with the second white key unit with D key 43 integrated
You may split it. In this case, the first white key unit and
One octave key combined with a second white key unit
When forming a panel unit, the position between these white key units
The first positioning means for performing the positioning is provided by these keyboard units.

In this case, both use a projection and a hole and
Technicians were stacked vertically. However, the common mounting part
It is not limited to these as positioning means betweenWhat
And otherStructure positioning means can also be employed.
For example, a groove may be used instead of the hole, and the groove may be used instead of the protrusion.
A protrusion may be formed to be engaged with and fitted into. Further, the common mounting portions are vertically overlapped.
Without engaging, to engage in the left and right direction, for example
A corrugated uneven portion may be formed at an end of the common attachment portion. Sa
In addition, this positioning means is used in the longitudinal direction of the key body.
Along with the positioning engagement part of each unit, for example,
It may be formed on each of the common mounting portions. Other positioning
