  In the present embodiment, one key unit KU is configured with one octave as a unit. However, the present invention is not limited to this, and any configuration including a plurality of keys may be used, and a key with two or more octaves is integrated. There may be. First, as shown in FIGS. 2 and 3, the white key unit KUW includes a first white key unit KUW1 in which white keys 20 of “D, F, A” in terms of pitch names are integrally connected at a base end portion 21. And a second white key unit KUW2 in which white keys 20 of “C, E, G, B” are integrally connected at the base end portion 21. The black key unit KUB is formed by integrally connecting a black key 40 of “C #, D #, F #, G #, A #” as a pitch name at a base end portion 41.

  Each of the first white key unit KUW1 and the second white key unit KUW2 is configured such that a white key body 23 is connected to each base end portion 21 via a thin plate-like vertical hinge portion 24 and a horizontal hinge 22, respectively. Is done. The vertical hinge portion 24 connected to the base end portion 21 is easily bent in the left-right direction and allows the free end portion of the white key body 23 to swing in the key arrangement direction (left-right direction) in the free state.

  The horizontal hinge 22 connected to the front side of the vertical hinge portion 24 is easily bent in the vertical direction, and in the free state, the free end portion of the white key body 23 is pushed and released with respect to the base end portion 21 and the vertical hinge portion 24. It can be rotated in the vertical direction. Further, an escape portion 25 for avoiding interference with the black key 40 when the black key 40 rotates is formed on the upper rear portion of the white key body 23 (see FIG. 3).

  The black key unit KUB is configured by connecting a black key body 43 to a base end portion 41 via a thin plate-like horizontal hinge 42. A portion of the rear portion of the black key body 43 that is connected to the horizontal hinge 42 is a flat plate portion 43a. The flat plate portion 43a is formed in a flat plate shape that is slightly thicker than the horizontal hinge 42, and the upper surface thereof is flush with the front portion of the upper surface of the key body portion 23 of the white key 20 from the escape portion 25 ( (See FIG. 3).

  As shown in FIG. 2, two horizontal hinges 42 are provided for each black key body 43 and are formed at positions separated from each other. Thereby, corresponding to each black key 40, through holes penetrating in the vertical direction are formed inside the base end portion 41, the black key body 43, and the two horizontal hinges 42. For example, as shown in FIG. 2, a part of the through holes are denoted by reference numerals, and among the black keys 40, the through holes 46 </ b> A are formed corresponding to the C # key, and the through holes 46 </ b> B are formed corresponding to the A #. .

Strictly speaking, the rotation centers of the white key body 23 and the black key body 43 are a connection point PW between the vertical hinge portion 24 and the horizontal hinge 22, and a connection point PB between the base end portion 41 and the horizontal hinge 42, respectively. (See FIG. 3).

  As shown in FIG. 3, the base end 21 of the second white key unit KUW2, the base end 21 of the first white key unit KUW1, and the base end 41 of the black key unit KUB are stacked and fitted in order from the bottom. These base end portions 21, 21, 41 constitute a common base end portion 30. In addition, a plurality of screw fastening holes 26, 26, and 44 are formed in the base end portions 21, 21, and 41, respectively. Abutting surfaces 27 and 28 facing each other are formed at the lower portion of the base end portion 21 of the second white key unit KUW2, which is also the lower portion of the common base end portion 30.

  On the other hand, as shown in FIG. 3, fixing portions 15 and 16 for fixing the common base end portion 30 correspond to the abutting surfaces 27 and 28 at the rear upper part of the key frame 10 slightly from the center in the front-rear direction. Is formed. The adhering portions 15 and 16 are respectively composed of a front end surface and a rear end surface of a portion protruding upward from the key frame 10. A plurality of screw holes 17 are formed at intermediate positions in the front-rear direction of the fixing portions 15 and 16 in the key frame 10 corresponding to the screw fastening holes 26 and 44.

  The abutment surfaces 27 and 28 of the common base end portion 30 are brought into contact with and opposed to the fixing portions 15 and 16, and screws 82 (see FIG. 1) are passed through the screw fastening holes 26 and 44 of the common base end portion 30. The common base end 30 is fastened and fixed to the key frame 10 by being screwed into the screw hole 17. As a result, the white key 20 and the black key 40 are rotated by the performance operation. In addition, the aspect of fixing the common base end portion 30 is not limited to this.

  In the integrated key unit KU, the horizontal hinge 42 of the black key 40 is located behind the horizontal hinge 22 of the white key 20. Therefore, the connection point PB is also located behind the connection point PW. As a result, the distance from the base end portion 41 (strictly speaking, the connection point PB) corresponding to the rotation fulcrum of the black key 40 to the free end portion is made as long as possible, and the performance operability of the black key 40 is improved. . Further, the positions of the vertical hinge portion 24 and the horizontal hinge 42 in the front-rear direction substantially coincide with each other, and the vertical hinge portion 24 of the white key 20 is located almost immediately below the horizontal hinge 42 of the black key 40. That is, the vertical hinge portion 24 is disposed by effectively using the space below the horizontal hinge 42. Furthermore, the upper end surface of the vertical hinge portion 24 is an inclined surface 24a that is slightly inclined downward toward the front (see FIG. 3). This prevents the horizontal hinge 42 and the vertical hinge portion 24 of the black key 40 from interfering with each other when the black key 40 is rotated downward.

  As shown in FIGS. 2 and 3, projecting pieces 31 (31 </ b> A and 31 </ b> B) spaced apart from each other are integrally formed at the base end portion 21 of the second white key unit KUW <b> 2. As shown in FIG. 3, the protruding piece 31 includes a horizontal extending portion 32 that extends forward from the front portion 21 a of the base end portion 21 of the second white key unit KUW <b> 2 and a substantially upper portion from the front end portion of the extending portion 32. It comprises a vertically extending portion 33 that extends. As shown in FIG. 2, the vertical extending portions 33 of the projecting pieces 31 </ b> A and 31 </ b> B are located in the through holes 46 </ b> A and 46 </ b> B in plan view, and the vertical extending portions 33 are formed in the through holes 46 </ b> A and 46 </ b> B. And protrudes upward from the horizontal hinge 42. The upper end portion of each vertical extending portion 33 is a flange portion 34 bent forward (see FIG. 3). These protruding pieces 31 are used as a gripping part for gripping the key unit KU when the key unit KU is attached or detached.

  In such a configuration, the key unit KU is assembled to the key frame 10 after the entire mass body 50 is assembled to the key frame 10. The operator moves the key unit KU from the front to the rear, and simultaneously lowers the lower end portions of all the drive hanging pieces 29 and 45 of the key unit KU to the lower engaging pieces 53 of the corresponding mass bodies 50.

This is a so-called temporarily fixed state. Accordingly, by gripping the projecting pieces 31A and 31B, the common base end portion 30 is secured while preventing the base end portions 21, 21, and 41 from coming apart and applying extra stress to the key unit KU. The fixing portions 15 and 16 can be engaged. In addition, if an unskilled operator is instructed that the protruding pieces 31A and 31B should be gripped, there is little risk of gripping inappropriate portions, and the wearing skill can be learned smoothly.

  On the other hand, when removing a key unit KU from the key frame 10, especially when other key units KU are arranged adjacent to each other on both sides thereof, there is almost no gap between the adjacent key units KU. Therefore, it is difficult to grip the common base end 30 of the key unit KU. However, if the protruding pieces 31A and 31B protruding above the horizontal hinge 42 of the black key 40 are gripped and the key unit KU is moved upward, the common base end 30 can be easily moved from the fixing portions 15 and 16. Can be detached. In addition, since the protruding piece 31 is provided with the flange 34, instead of directly holding the protruding piece 31 with a finger, a predetermined locking tool is used, and the locking tool is hooked on the flange 34. The key unit KU may be removed.

  According to this embodiment, it is possible to utilize the projecting portions 31 as grip portions, the attachment and detachment of the key unit KU on the key frame 10 can be facilitated. Further, the protruding piece 31 is integrally connected to the front portion 21a of the base end portion 21, and the vertically extending portion 33 of the protruding piece 31 is located in the through hole 46 in a plan view, and the base end portion 21 is provided. Is close to. Thereby, the force at the time of gripping the protruding piece 31 is directly transmitted to the common base end portion 30, and the operation is almost the same as holding the key unit KU by gripping the common base end portion 30 itself, The key unit KU can be stably held. Moreover, since the base end portion 21 on which the protruding piece 31 is provided is the base end portion 21 of the second white key unit KUW2 in the lowermost layer, when the protruding piece 31 is gripped, the base end portions 41, 21, The laminated fitting state of 21 is not easily broken (does not break).

  Also, the first and second white key units KUW1, KUW2, and the black key unit KUB are molded with a mold, and after molding, they are taken out from the mold, and their base ends are stacked to form one key unit KU. It is easy to grip the key unit KU so that it does not fall at the common base end 30 by gripping the protruding piece 31 even when packing it, carrying it to the assembly site, and assembling it to the keyboard device. It is. Therefore, the workability | operativity at the time of taking out from a metal mold | die and handling it collectively as one key unit after shaping | molding by a metal mold | die can be improved.

  The protruding piece 31 protrudes upward from the horizontal hinge 42 of the black key 40, but is not limited thereto. That is, if the tip of the protruding piece 31 can be gripped with a finger or the like through the through hole 46, or if the locking tool or the like can be locked to the collar 34 of the protruding piece 31, the protruding piece 31 is slightly shortened. The upper end of the installation piece 31 may be lower than the horizontal hinge 42.
