Abstract

<P>PROBLEM TO BE SOLVED: To provide a keyboard instrument which can accurately detect a key depression state independently of individual differences of rubber switches. <P>SOLUTION: In a keyboard instrument 1, a projecting part 71 is formed on the depression object part 70a of a rubber switch 70 facing the tail part 21 of a hammer 20. Meanwhile, a recessed part 22 capable of being fitted to the projecting part 71 is formed on the depression surface 21a of the tail part 21 facing the rubber switch 70. Since the recessed part 22 on the depression surface 21 and the projecting part 71 on a depression object surface 71a are fitted to each other when the rubber switch 70 is depressed to control deviation in the horizontal direction of the rubber switch 70 in this keyboard instrument 1, differences of deviation in the horizontal direction resulting from differences of elastic force among individual rubber switches 70 are eliminated. Consequently, the key depression state is accurately detected, so that key depressions on keyboards for the same sounds can be detected at the same timing between keyboard instruments 1 provided with rubber switches 70. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【０００１】
【発明の属する技術分野】
本発明は、鍵盤楽器に関する。
【０００２】
【従来の技術】
電子ピアノで用いられる従来の鍵盤装置１は、図１に示すように、鍵盤１０、ハンマー２０、シャーシ３０を備えている。そしてシャーシ３０は、棚板４０の上方に設置され、具体的には、その前方部と後方部に配置された二つの支持具５０により棚板４０から所定高さ位置に支持され、また、二つの支持具５０を渡して設けられたリブ６０によりその中間点が支持されている。そして、鍵盤１０は、シャーシ３０の後方端に揺動可能に取り付けられ、シャーシ３０の前方端の上方に鍵盤１０の遊端側が配置されるよう設置されている。またハンマー２０は、シャーシ３０中央の後方寄りの上面に揺動可能に取り付けられ、シャーシ３０に設けられた挿通孔３１を通し、錘２５を備える遊端側がシャーシ３０の前方端の下方に位置するよう設置されている。
【０００３】
また、ハンマー２０は、シャーシ３０に揺動可能に取り付けられている揺動軸２６の後方側にテール部２１を備え、鍵盤１０は、このテール部２１に対向する位置に突起１１を備えている。そして、鍵盤楽器１は、このテール部２１の下側の面である押下面２１ａに対向するシャーシ３０上にゴムスイッチ７０を備えている。
【０００４】
さらに、ゴムスイッチ７０は、テール部２１に押下される方向に沿って並設され、接点間の距離が異なる２対の接点を、ゴム製の本体の内部に備えている。
このように構成された鍵盤装置１では、鍵盤１０が押鍵されると突起１１がテール部２１を押下し、さらにテール部２１がゴムスイッチ７０を押下すると、ゴムスイッチ７０が備えている各接点が順次接触する。
【０００５】
そして、図示しない制御装置では、ゴムスイッチ７０が押下され、押鍵を検出すると、押鍵された鍵盤１０に応じた音を発音すると共に、ゴムスイッチ７０内に備えられた各接点が接触するタイミングのズレを検出すると、このズレの長短により鍵盤１０の押下速度（ベロシティ）、すなわち押鍵の強さが分かるので、このズレの長短に対応する押鍵の強さの音を発音する制御を行っている（特許文献１）。
【０００６】
尚、上記従来の技術の説明では、ハンマー２０がゴムスイッチ７０を押下するものの例について説明したが、鍵盤１０が直接ゴムスイッチ７０を押下するものもある（特許文献２）。
また、上記従来の技術の説明では、ハンマー２０の遊端側が、フレーム３０の前方に配置された例について説明したが、ハンマー２０の遊端側が鍵盤１０の後端よりも後方側に配置され、ハンマー２０の遊端側の上部に設置された擬似アクションを動作させる構造のものもある（特許文献３）。

【発明が解決しようとする課題】
しかし、各ゴムスイッチ７０には個体差があり、外見的には同じゴムスイッチ７０でもその弾性力に違いがある。一方、鍵盤１０やハンマー２０は、シャーシ３０に対し揺動可能に取り付けられているので、ゴムスイッチ７０はこれらに鉛直に押下されるのではなく、やや斜め下方に向かって押下される。そのため、ゴムスイッチ７０は押下されるとき水平方向にズレ、そのズレ幅は弾性力の違いにより異なるので、その押下量も異なってくる。その結果、鍵盤楽器１が異なると同じ音の鍵盤１０でも同じタイミングで押鍵を検出できなかったり、同じ音の鍵盤１０を同じ強さで押鍵しても同じベロシティを検出できない等、押鍵状態を正確に検出できないという問題があった。
【０００９】
そこで本発明では、ゴムスイッチの個体差によらず、押鍵状態を正確に検出できる鍵盤楽器を提供することを目的とする。
【００１０】
【課題を解決するための手段及び発明の効果】
上述した問題点を解決するためになされた請求項１に記載の鍵盤楽器は、鍵盤が押下されたとき、該鍵盤あるいは該鍵盤に連動する連動部材に押される位置に配置されたゴムスイッチを備える鍵盤楽器において、前記鍵盤あるいは前記連動部材が前記ゴムスイッチを押す押下部、及び、前記押下部に対向する前記ゴムスイッチの被押下部に、互いに嵌合可能な嵌合部が形成されていることを特徴とする。
【００１１】
この鍵盤楽器では、ゴムスイッチが押下されるとき押下部及び被押下部の各嵌挿部が互いに嵌挿し、ゴムスイッチの水平方向のズレが規制されるので、個々のゴムスイッチの弾性力の違いによる水平方向へのずれの差がなくなる。
従って、本発明が適用された鍵盤楽器同士では、ゴムスイッチの個体差による影響がないので、同じ音の鍵盤であれば同じタイミングで押鍵を検出できるなど、押鍵状態を正確に検出することができる。
【００１２】
尚、嵌合部については、押下部に嵌合部である凸部、被押下部に嵌合部である凹部、あるいは、押下部に凹部、被押下部に凸部のように、いずれに凸部あるいは凹部を設けてもよい。また、凸部あるいは凹部の形状は、楕円形状、円形状等、どのような形状でもよい。
【００１３】
次に、請求項２に記載したように、連動部材としてはハンマーや、擬似アクションを構成する各部品（ウィッペン等）が好ましい。
次に、請求項３に記載した鍵盤楽器では、ゴムスイッチが、押下部に押下される方向に沿って並設され、接点間の距離が異なる２対の接点を備えているので、各接点の接触タイミングから、押鍵の速さ（ベロシティ）すなわち押鍵の強さが分かる。本発明の鍵盤楽器では、ゴムの弾性力の違いによる横方向へのズレが規制されるので、ゴムの弾性力の違いによる横方向へのずれの差がなくなる。そのため本発明のようなゴムスイッチを備える鍵盤楽器同士では、同じ音の鍵盤を同じ速さで押鍵するのであれば同じベロシティを検出できるなど、押鍵状態を正確に検出することができる。
【００１４】
【発明の実施の形態】
[第１実施形態]
以下、本発明が適用された実施の形態について図面を用いて説明する。
ここで、図１は、本第１実施形態の鍵盤装置の断面図である。図２及び図４は、図１の一部拡大図である。図３は、ゴムスイッチ７０の断面図である。尚、図２では、説明に必要な構成のみ拡大して示してある。
【００１５】
尚、以下の説明では、従来の技術の欄で説明した部分と重複する部分については、説明を省略して、本発明の特徴部分が現れている部分について説明する。また、従来の技術の欄で説明した鍵盤装置を同じ構成については、同一符号を用いて説明する。
【００１６】
本実施形態の鍵盤装置１は、図１に示すように、鍵盤１０、ハンマー２０、シャーシ３０、支持具５０，５０、リブ６０、ゴムスイッチ７０を備え、棚板４０上に設置されている。本実施形態の鍵盤楽器１は、ハンマー２０を備えたいわゆる電子ピアノである。
【００１７】
本実施形態の鍵盤楽器１は、図２に示すように、ハンマー２０のテール部２１に対向するゴムスイッチ７０の被押下面７０ａ（本発明の被押下部に相当）には凸部７１（本発明の嵌合部に相当）が形成されている。一方、ゴムスイッチ７０に対向するテール部２１の押下面２１ａ（本発明の押下部に相当）には、凸部７１に嵌合可能な凹部２２（本発明の嵌合部に相当）が形成されている。
【００１８】
また、ゴムスイッチ７０は、図３に示すように、水平面に鉛直な方向に沿って並設され、接点間の距離（図中符号αとβ）が異なる２対の接点（図中符号７５ａと７５ｂ、７６ａと７６ｂ）を備えている。このゴムスイッチ７０を用いると、２対の接点（符号７５ａと７５ｂ、７６ａと７６ｂ）間の距離（符号α、β）が異なるので、各接点の接触タイミングから、押鍵の速さ（ベロシティ）すなわち押鍵の強さが分かる。そのため、本実施形態の鍵盤楽器１では、図示しない制御装置により、ゴムスイッチ７０で検出した各接点の接触タイミングに基づいて発音される音の強さが決定され、その音の強さで発音する制御がなされる。
【００１９】
以上のように構成された鍵盤楽器１では、ゴムスイッチ７０が押下されるとき押下面２１ａの凹部２２及び被押下面７１ａの凸部７１が互いに嵌挿し、ゴムスイッチ７０の水平方向のズレが規制されるので、個々のゴムスイッチ７０の弾性力の違いによる水平方向へのズレの差がなくなる。
【００２０】
従って、本実施形態のようなゴムスイッチ７０を備える鍵盤楽器１同士であれば、同じ音の鍵盤であれば同じタイミングで押鍵を検出でき、また、同じ音の鍵盤１０を同じ速さで押鍵すれば同じベロシティを検出できるなど、押鍵状態を正確に検出することができる。
【００２１】
尚、本実施形態では、押鍵面２１ａに凹部２２、被押鍵面７０ａに凸部７１を形成したが、図４に示すように、押鍵面２１ａに凸部２３を形成し、被押鍵面７０ａに凹部７２を形成してもよい。
[第２実施形態]
次に、本発明の第２実施形態について説明する。尚、本実施形態では、第１実施形態と異なる点のみ説明する。
【００２２】
ここで、図５は、本第１実施形態の鍵盤装置の断面図である。図６及び図７は、図５の一部拡大図である。
本実施形態の鍵盤楽器１は、第１実施形態の鍵盤楽器が備えていたハンマー２０を備えておらず、鍵盤１０が、シャーシ３０に設置されたゴムスイッチ７０を直接押下する構成になっている。本実施形態の鍵盤楽器１は、いわゆるオルガンタッチの鍵盤である。
【００２３】
そして本実施形態の鍵盤楽器１は、鍵盤１０の下部であって、ゴムスイッチ７０に対向する位置に突起１１が形成され、図６に示すように、その突起１１の下面である押下面１１ａに凸部１２が形成されている。一方、この押下面１１ａに対向するゴムスイッチ７０の被押下面７０ａには、凸部１２が嵌挿可能な凹部７１が形成されている。
【００２４】
以上説明した鍵盤楽器１では、第１実施形態と同様の作用効果を奏する。
尚、本実施形態では、押下面１１ａに凸部１２、被押鍵面７０ａに凹部７１を形成したが、図７に示すように、押下面１１ａに凸部１３を形成し、被押鍵面７０ａに凹部７２を形成してもよい。
【００２５】
尚、本発明の実施の形態は、上記実施形態に何ら限定されるものではなく、本発明の技術的範囲に属する限り種々の形態を採り得ることはいうまでもない。

[Problems to be solved by the invention]
However, each rubber switch 70 has an individual difference, and the same rubber switch 70 has a difference in elasticity in appearance. On the other hand, since the keyboard 10 and the hammer 20 are swingably attached to the chassis 30, the rubber switch 70 is not pressed vertically vertically, but is pressed slightly obliquely downward. Therefore, when the rubber switch 70 is depressed, the rubber switch 70 is displaced in the horizontal direction, and the displacement width varies depending on the difference in elastic force, so that the depression amount also varies. As a result, if the keyboard instruments 1 are different, the key presses cannot be detected at the same timing even on the keyboard 10 of the same sound, or the same velocity cannot be detected even if the keys 10 of the same sound are pressed at the same strength. There was a problem that the state could not be detected accurately.
[0009]
In view of the above, an object of the present invention is to provide a keyboard instrument that can accurately detect a key-depressed state irrespective of individual differences of rubber switches.
[0010]
Means for Solving the Problems and Effects of the Invention
The keyboard instrument according to claim 1, which has been made to solve the above-mentioned problem, includes a rubber switch arranged at a position where the keyboard or an interlocking member interlocked with the keyboard is pressed when the keyboard is pressed. In the keyboard musical instrument, a fitting portion capable of fitting with each other is formed in a pressing portion where the keyboard or the interlocking member presses the rubber switch, and a pressed portion of the rubber switch facing the pressing portion. It is characterized by.
[0011]
In this keyboard instrument, when the rubber switch is pressed, the pressed portions and the pressed portions are fitted into each other, and the horizontal displacement of the rubber switch is regulated. The difference in the displacement in the horizontal direction due to the difference is eliminated.
Therefore, since the keyboard musical instruments to which the present invention is applied are not affected by the individual difference of the rubber switch, it is necessary to accurately detect the key depression state, for example, the key depression can be detected at the same timing if the keyboard has the same sound. Can be.
[0012]
Regarding the fitting part, the convex part which is the fitting part in the pressed part, the concave part which is the fitting part in the pressed part, or the concave part in the pressed part and the convex part in the pressed part A portion or a concave portion may be provided. Further, the shape of the convex portion or the concave portion may be any shape such as an elliptical shape and a circular shape.
[0013]
Next, as described in claim 2, as the interlocking member, a hammer or each component (such as a whippen) constituting a pseudo action is preferable.
Next, in the keyboard instrument according to the third aspect, the rubber switches are provided side by side along the direction of being pressed by the pressing portion, and are provided with two pairs of contacts having different distances between the contacts. From the contact timing, the key pressing speed (velocity), that is, the key pressing strength is known. In the keyboard musical instrument of the present invention, the lateral displacement due to the difference in the elastic force of the rubber is restricted, so that the difference in the lateral direction due to the difference in the elastic force of the rubber is eliminated. Therefore, a keyboard instrument having a rubber switch as in the present invention can accurately detect a key-depressed state, such that the same velocity can be detected if keys of the same sound are depressed at the same speed.
