 BACKGROUND ART Conventionally, a wooden keyboard has been generally used as a keyboard of a keyboard instrument such as a grand piano. As shown in FIG. 6, this wooden keyboard has ivory and synthetic resin plates attached to the upper surface P2 and the front surface P3 of the key P1, but the left and right side surfaces P4 of the key P1 are pianos. In order to improve the impression when you play, the surface of the wood is normally exposed.

However, since the side surface P4 of the key P1 is directly touched with a finger or the like when the adjacent key P1 is pressed down, the side surface P4 of the piano key P1 that has been played to some extent becomes dirty due to a finger or the like. There was a problem. Therefore, at the time of maintenance of the piano, the side surface P4 of the key P1 was scraped off with sandpaper one by one to remove the dirt, but this method had a problem that the maintenance was very troublesome. Further, if the side surface P4 of the key P1 is cut too much, the width of the key P1 becomes narrow and the performance is hindered. Therefore, another problem that the cleaning work cannot be repeated many times occurs. .

The present invention has been made to solve the above problems, and an object of the present invention is to provide a wooden keyboard for a keyboard musical instrument, which can prevent dirt from adhering to the side surface of the key and can simplify the maintenance of the musical instrument. To do.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A shows a perspective view of one key of the wooden keyboard of the first embodiment, and FIG. 1B shows an exploded view of the key. The wooden keyboard of the first embodiment is a so-called ivory keyboard in which ivory is used on the upper surface of the keyboard.

As shown in FIGS. 1A and 1B, in the wooden keyboard of the first embodiment, a square pole wooden material is used as the core material 2 of the key 1. An ivory plate 3 is attached to the upper surface 2a of the core material 2, a white celluloid plate 4 is attached to the front surface 2b of the core material 2, and a sealer is attached to both side surfaces 2c and 2d of the core material 2. The transparent antifouling layers 5a and 5b (collectively referred to as 5) that have been applied are formed.

Next, the manufacturing process of this wooden keyboard will be described with reference to FIG. First, an adhesive such as acetone is applied to the front surface 10a of a wide keyboard material 10 (which becomes the plurality of keys 1) to attach the long celluloid plate 4. Next, a cutting operation is performed in which the core material 2 of each key 1 (with the celluloid plate 4) is cut out from the keyboard material 10 to which the celluloid plate 4 is attached.

Next, a sealer is applied to both side surfaces 2c and 2d of the cut core material 2 of the key 1 to form a stain prevention layer 5. Next, the ginseng 11 and the ivory plate 3 are arranged on the upper surface 2a of the core material 2 of the key 1, and the ivory plate 3 is attached to the core material 2 by using an adhesive such as glue on the ginseng 11. Complete 1.

In the wooden keyboard of this embodiment manufactured as described above, the side surface of the key 1 is coated with a sealer to form the stain prevention layer 5, so that the stain prevention layer 5 can be used for playing. Even if a finger touches the side surface of the key 1, the side surface of the key 1 is not soiled. Therefore, there is an effect that almost no effort is required to remove the dirt during maintenance. Further, unlike the conventional case, it is not necessary to scrape off the side surface of the key 1 to remove dirt, which is advantageous in that deformation of the key 1 due to excessive cutting can be prevented. In addition, since the antifouling layer 5 is transparent, a beautiful pattern due to the grain of the side of the key 1 can be seen during the performance, which has the effect of not impairing the appearance.

Next, a second embodiment will be described with reference to the drawings. FIG. 3A shows a perspective view of the key of the wooden keyboard of the second embodiment, and FIG. 3B shows an exploded view of the key. The wooden keyboard of the second embodiment uses an artificial material (for example, artificial ivory or acrylate) on the upper surface and the front surface of the key.

As shown in FIGS. 3 (a) and 3 (b), in this wooden keyboard, artificial ivory integrally molded in a substantially L shape on the upper surface 22 a and the front surface 22 b of the wooden core material 22 of the key 21. Alternatively, a surface material 23 made of acrylite is attached. On both side surfaces 22c and 22d of the core material 22 of the key 21, varnish is applied on the sealer to form slightly glossy and transparent stainproof layers 24a and 24b (collectively referred to as 24).

Next, the manufacturing process of this wooden keyboard will be described with reference to FIG. First, a cutting operation for cutting out the core material 22 of each key 21 from the wide keyboard material 20 is performed. Next, a sealer is applied to both side surfaces 22c and 22d of the core material 22 of the cut key 21 and then a varnish is applied to form a stain prevention layer 24.

Next, a surface material 23 made of a substantially L-shaped artificial ivory is attached by using a thinner adhesive so as to cover the upper surface 22a and the front surface 22b of the core material 22 of the key 21. To complete. When the substantially L-shaped surface material 23 is made of acrylite, it is desirable to use a vinyl acetate adhesive as the adhesive.

In the wooden keyboard of this embodiment manufactured as described above, the sealer and varnish are applied to the side surface of the key 21 to provide the transparent stainproof layer 24, as in the first embodiment. Even if the key 21 is used for a long period of time, the side surface of the key 21 does not get dirty, and the effect of reducing the dirt during maintenance is reduced. In addition, it is possible to prevent the key 21 from being deformed due to excessive shaving, and moreover, the beautiful impression due to the grain of the side surface of the key 21 is not significantly impaired.

It is needless to say that the present invention can be implemented in various modes other than the above-described embodiment without departing from the scope of the present invention. For example, as shown in FIG. 5 (a), there are four types of keys that make up the keyboard, but the antifouling layer formed on the side surface of the key has a notch of the type shown in FIG. 5 (b). It may be up to the portion, and for the type shown in FIG. 5 (c), it may be up to the end of the plate material attached to the upper surface.
