【発明の詳細な説明】
〔産業上の利用分野〕
この発明は、１！子オルガン、電子ピアノ、携帯用鍵盤
電子楽器等の鍵盤装置に関し、特に演奏者の感情表現に
よる微妙な鍵操作を正確に演奏楽音に現わすことができ
る鍵盤装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] This invention has the following features: 1! The present invention relates to a keyboard device for a child organ, an electronic piano, a portable keyboard electronic musical instrument, etc., and in particular to a keyboard device that can accurately express subtle key operations based on the emotional expression of a performer in the musical sounds played.
この発明は、複数の鍵と、その各部をそれぞれ回動可能
に支持する鍵回動支持部材とからなる鍵盤装置において
、その鍵支持部を鍵と鍵回動支持部材のいずれか一方に
設けた円柱状又は円筒状の軸部と、他方に設けた上記軸
部と相対回動可能に嵌合する軸受部とから構威し、これ
らの軸部と軸受部の間に、ＩＩの回動操作量に応じて多
数のパルスを発生するパルス発生手段を設けることによ
り、演奏者の鍵タッチの仕方による複雑な感情表現を可
能にし、しかもそれをコンパクトで安価に実現できるよ
うにしたものである。The present invention provides a keyboard device comprising a plurality of keys and a key rotation support member that rotatably supports each part of the keys, in which the key support portion is provided on either the key or the key rotation support member. It consists of a cylindrical or cylindrical shaft part and a bearing part provided on the other side and fitted to the shaft part so as to be relatively rotatable, and between these shaft parts and the bearing part, there is a rotary operation of II. By providing a pulse generating means that generates a large number of pulses according to the amount of pulses, it is possible to express complex emotions by the manner in which the player touches the keys, and this can be realized compactly and inexpensively.
電子オルガン等の電子楽器は、基本的には押鍵によるキ
ースイッチの開閉によって発音を制御するようになって
いたが、それだけでは発音特性が単調で、ピアノのよう
に演奏者の感情を表現した演奏ができない。The sound of electronic instruments such as electronic organs was basically controlled by opening and closing key switches by pressing the keys, but this alone resulted in monotonous sound characteristics, and it was difficult to express the performer's emotions like a piano. I can't play.
そこで、押鍵時の力の相違によって発音、特性に変化を
与えて感情表現を可能にするため、いわゆるタッチレス
ポンス機能を持たせる技術が種々開発されている。Therefore, in order to make it possible to express emotions by changing the pronunciation and characteristics depending on the force applied when pressing a key, various technologies have been developed to provide a so-called touch response function.
このタッチレスポンス機能とは、押鍵時の立上り及び押
鍵後の音の持続状態における演奏者の指の動きに応じて
、発生する楽音の音量、音高、音色等を制御してタッチ
コントロールをかけることである。This touch response function is a touch control function that controls the volume, pitch, timbre, etc. of the musical sound generated according to the movement of the performer's fingers during the rise when a key is pressed and the sound that continues after the key is pressed. It is to multiply.
そのために、例えば実公昭５４−６４２１号公報に見ら
れるように、押鍵によって磁石とコイルとを相対変位さ
せて誘導起電力を発生させ、その出力をタッチレスポン
スのコントロール信号として利用するものがある。For this purpose, for example, as seen in Japanese Utility Model Publication No. 54-6421, there is a device that generates an induced electromotive force by relatively displacing a magnet and a coil by pressing a key, and uses the output as a control signal for touch response. .
また、実公昭５７−３１３３１号公報に見られるように
、押鍵に応じて導電性弾性部材を変形させて基板上に列
設された複数の固定接点間を順次短絡して抵抗値を段階
的に変化させ、それを電圧に変換してタッチレスポンス
のコントロール信号とするものもある。In addition, as seen in Japanese Utility Model Publication No. 57-31331, a conductive elastic member is deformed in response to a key press, and a plurality of fixed contacts arranged in a row on a board are successively short-circuited to gradually change the resistance value. There are also devices that change the voltage to a voltage and use it as a touch response control signal.
さらに、特開昭５８−１８８１２号公報に見られるよう
に、押鍵により回転円盤状の可動接点が回転し、基板上
の複数の固定接点に順次接して発生するデジタル信号を
用いて、演奏に効果を与えることも考えらｈでいる。Furthermore, as seen in Japanese Patent Application Laid-Open No. 58-18812, a rotary disk-shaped movable contact rotates when a key is pressed, and digital signals generated by successively contacting multiple fixed contacts on a board are used to generate musical performances. I can't even think of giving it any effect.
しかしながら、これらの従来技術はそれぞれ次のような
問題点があった。However, each of these conventional techniques has the following problems.
１番目と２番目のものは、いずれもアナログ的な信号処
理によってタッチレスポンスを付与するので、電子楽器
のハードウェアが増大してコスｌ−アップにつながるほ
か、安定した動作を行なわせることが一般に困難である
。なお、２番目のものでは固定接点のピッチをあまり小
さくすることは、接点形成上からも配線が膨大になるこ
とからも困難であるから、木目細かなコントロールは無
理である。The first and second methods both provide touch response through analog signal processing, which increases the hardware of the electronic musical instrument, leading to an increase in cost.In addition, it is generally necessary to ensure stable operation. Have difficulty. In the second case, it is difficult to make the pitch of the fixed contacts too small, both from the viewpoint of contact formation and because the amount of wiring becomes enormous, so fine control is impossible.
３番目のものは、デジタル信号シこよるタッチレスポン
スの付与が可能になるので、特に近年主流となっている
マイクロコンピュータを用いたデジタル信号処理によっ
て楽音を発生させる電子楽器に採用するのに都合がよい
が、やはり接点配列によって信号発生精度が制限されて
しまうし、出力ラインも接点数だけ必要になる。また、
その構造が複雑で設計の自由度が制約されるばかりか、
耐久性の点でも問題がある。The third method is suitable for use in electronic musical instruments that generate musical tones through digital signal processing using microcomputers, which has become mainstream in recent years, since it is possible to provide a touch response using digital signals. Although this is good, the signal generation accuracy is still limited by the contact arrangement, and the number of output lines required is equal to the number of contacts. Also,
Not only is the structure complex and the degree of freedom in design is restricted, but
There are also problems with durability.
この発明は、従来の電子楽器の鍵盤装置におけるこのよ
うな問題を解決し、演奏者による押鍵操作の仕方による
木目細かなタッチコントロールをデジタル信号処理によ
って、ハードウェアの増加が少ない簡単な構成によりコ
ンパクトで安価に実現できるようにすることを目的とす
る。This invention solves these problems in conventional keyboard devices for electronic musical instruments, and uses digital signal processing to provide fine-grained touch control based on the way the player presses the keys, using a simple configuration that requires less hardware. The aim is to make it compact and inexpensive.
この発明は上記の目的を達成するため、複数の鍵と、そ
の各軸をそれぞれ回動可能に支持する鍵回動支持部材と
からなる鍵盤装置において、上記鍵回動支持部材に、鍵
の回動操作量に応じて多数のパルスを発生するパルス発
生手段を設けたものである。In order to achieve the above object, the present invention provides a keyboard device comprising a plurality of keys and a key rotation support member that rotatably supports each axis of the keys. This device is provided with a pulse generating means that generates a large number of pulses in accordance with the amount of dynamic operation.
そして、そのパルス発生手段は、軸部と軸受部のいずれ
か一方に設けた磁気的変化誘発部材と、他方に設けた磁
気的変化検出部材とからなるようにするのが好ましい。Preferably, the pulse generating means includes a magnetic change inducing member provided on one of the shaft portion and the bearing portion, and a magnetic change detecting member provided on the other.
この発明による鍵盤装置は、鍵操作によりその鍵の回動
操作量及び操作速度に対応する多数のパルスをそのパル
ス数より極めて少ない出力ラインから、発生するので、
例えば押鍵開始後一定時間内での発生パルス数、あるい
は押鍵後の発生パルス数等に対応して、音量、音色、ピ
ッチ、テンポ。In the keyboard device according to the present invention, when a key is operated, a large number of pulses corresponding to the rotational operation amount and operation speed of the key are generated from the output line which is much smaller than the number of pulses.
For example, the volume, timbre, pitch, and tempo correspond to the number of pulses generated within a certain period of time after the start of a key press, or the number of pulses generated after a key press.
ビブラート、トレモロ等の楽音制御パラメータを多段階
に変化させることができる。Musical tone control parameters such as vibrato and tremolo can be changed in multiple stages.
したがって、演奏者による鍵操作の仕方によって、パル
スの発生パターンが変わり、そのパルス数に応じた木目
細かなタッチコントロールをデジタル信号処理によって
行うことができ、ハードウェアの増加も少なくて済む。Therefore, the pulse generation pattern changes depending on the way the player operates the keys, and fine touch control according to the number of pulses can be performed by digital signal processing, and there is no need to increase the amount of hardware.
また、鍵支持部を軸と軸受部とから構成してその間にパ
ルス発生手段を設けたので、その検出回路を極めてコン
パクトで且つ安価に実現することができる。Furthermore, since the key support section is composed of the shaft and the bearing section, and the pulse generating means is provided therebetween, the detection circuit thereof can be realized extremely compactly and at low cost.
さらに、そのパルス発生手段を磁気的変化誘発部材と磁
気的変化検出部材とから構成すれば、簡単な構成で極め
て安定したパルス発生が可能になる。Furthermore, if the pulse generating means is composed of a magnetic change inducing member and a magnetic change detecting member, extremely stable pulse generation can be achieved with a simple configuration.

By pressing downward against the biasing force of the spring 7, a large number of pulses can be generated depending on the rotational displacement amount and speed.
次に、上記のように構成した実施例の作用を説明する。Next, the operation of the embodiment configured as described above will be explained.
いま、第１図に示す状態から鍵１の押鍵部１ａを板ばね

＠１が軸部材４の軸部４ａを支点として図で下方へ回動
