BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A reed for a keyboard instrument according to an embodiment of the present invention will be described. FIG. 1 shows a state in which a part of a reed 1 of a keyboard instrument is cut away to show a side surface portion. In the figure, the reed 1 is a front reed 2 assembled before and after a reed middle bundle 3. And a reed 4 and a reed 5 assembled on the upper surface of the reed bundle 3. The front 2 of the reed, the rear 4 of the reed, and the middle 5 of the reed extend parallel to each other in the direction in which the keyboards 6 are arranged.
It is fixed between the reeds.

As shown in FIG. 1 and FIG.
The five block members 5a to 5e are integrally connected to each other, and solid spruce members whose grain directions are different from each other are used except for two predetermined block members 5b and 5d. The block material 5b, 5d of this reed 5
Has a number of balance pins P along the direction in which the keyboard 6 is arranged.
1 (only two are shown in the figure) is implanted, and these block members 5b and 5d are made of plywood formed by laminating hardwood, for example, single veneer or maple. In the reed 5, a large number of white keys 6a and black keys 6b (only one each shown in the drawing) are placed in engagement with each balance pin P1. The keys 6a and the black keys 6b swing about the balance pins P1 as a fulcrum when their front ends are depressed during the performance.

As shown in FIG. 1 and FIG. 3, the front 2 of the reed is formed by integrally joining six block members 2a to 2f back and forth, and two block members 2b,
Except for 2e, solid spruce materials whose grain directions are different from each other are used. A large number of front pins P2 (2 in the figure) are attached to the block members 2b and 2e at two predetermined portions.
The front pin P2 is engaged with a not-shown groove at the front end of the white key 6a and the black key 6b, so that the white key 6a and the black key 6b When swinging, they are guided so that they do not move left and right. Similarly, the block members 2b and 2e at the two predetermined sites where the front pins P2 are implanted are also made of hardwood plywood.

The operation of manufacturing the reed of the keyboard instrument of the present invention configured as described above will be described. First, wood having a predetermined material and wood grain is selected, and a front reed 2, a reed middle bundle 3, and a reed Afterwards, it is processed for reed 4, middle 5 and reed wife. At this time, beech or maple veneer veneers are laminated and bonded for the block members 5b and 5d in the reed 5 and for the block members 2b and 2e in the front 2 of the reed to form a plywood. The plywood formed in this way has a better yield at the time of processing and is economically superior to the case of using solid beech wood or maple wood. The production cost when producing the block material can be reduced. Also,
This plywood has the same strength as beech wood or maple wood which is also solid.

Next, the respective members are combined and adhered to form a reed 1 having a front reed 2, a middle reed bundle 3, a rear reed 4, a middle reed 5, and a reed wife. Next, using a drill or the like, the block members 5b and 5d in the reed 5 and the block members 2b and
A prepared hole for driving each of the pins P1 and P2 is made at a predetermined location 2e. Thereafter, each of the pins P1 and P2 is driven into this pilot hole and fixed. At this time, each block material 2b,
Since the plywood constituting 2e, 5b, 5d has the same strength as the solid material of beech or maple as described above, the pins P1, P2 which are driven in are firmly fixed and held. You. In addition, since the front reed 2 and the middle reed 5 have a structure in which blocks having different grain directions are in front of and behind each other, the strength is higher than that of the single-plate structure, and the weight of the keyboards 6a and 6b and the playing time are improved. Operation can be well supported. Further, the block members 2b, 2e, 5b, 5d
Since the other block members are made of solid spruce material, the blocks are deformed while receiving the weight of the keyboards 6a and 6b, so that the keyboards become familiar as a whole and can support the keyboard in a well-balanced manner.

In the above embodiment, hardwood plywood is used for both the portion where the pin P1 is to be implanted in front of the reed 2 and the portion where the pin P2 is to be implanted in the reed 5, but only one of them may be used. . Further, the hardwood is not limited to beech or maple, and may be any material having a strength capable of firmly fixing and holding the implanted pins P1 and P2.
