Description
【考案の詳細な説明】 本考案は電子楽器における鍵装置に関する。[Detailed explanation of the idea] The present invention relates to a key device for an electronic musical instrument.
元来、電子楽器における鍵とキースイッチとの関係は、
各鍵が所定のストローク押下げられたとき、キースイッ
チが作動し、発音が行なわれるように設計されている。Originally, the relationship between keys and key switches in electronic musical instruments was
The design is such that when each key is pressed down a predetermined stroke, the key switch is activated and a sound is produced.
しかしながら設計上の誤差や取付状態等により、ばらつ
きが生ずる。However, variations occur due to design errors, installation conditions, etc.
かかるばらつきを調整する手段としては錠本体の下面に
設けた緩衝材の厚さを変えたり、キースイッチのアクチ
ュエータの長さを調整したりする必要があった。As a means to adjust such variations, it is necessary to change the thickness of the cushioning material provided on the lower surface of the lock body, or to adjust the length of the key switch actuator.
そのためにはいちいち鍵を取外さなければならず多大の
手数と労力を必要とする不都合があった。For this purpose, the key must be removed each time, which is inconvenient and requires a great deal of time and effort.
本考案は鍵を取外すことなく、組込んだままの状態で簡
単に調整出来る鍵装置を提供することを目的とするもの
で、熱可塑性プラスチックにより形成された錠本体１の
底板２のキースィッチ３操作部４を、切溝５により、遊
離させて舌片６を形成し、該舌片６の根部に上方に突出
する突条９を形成して戒る。The purpose of the present invention is to provide a key device that can be easily adjusted while the key is still installed without removing the key. The operating part 4 is separated by the cut groove 5 to form a tongue piece 6, and a protrusion 9 that projects upward is formed at the root of the tongue piece 6 to prevent it.
図面において８は操作部４の下面に設けた緩衝材、９は
アクチェータ、１０はシャーシを示す。In the drawings, reference numeral 8 indicates a cushioning material provided on the lower surface of the operating section 4, 9 indicates an actuator, and 10 indicates a chassis.
かくて、第３図示のように加熱鏝ａをその下面の凹条す
に突条７を嵌合した状態で舌片６の根部を加熱し、該加
熱鏝ａを所望の方向へ傾動させることにより舌片６を上
動又は下動させて錠本体１の所定の下動ストロークにお
けるキースイッチ３の作動点を調整する。Thus, as shown in the third diagram, the root of the tongue piece 6 is heated with the protrusion 7 fitted into the groove on the lower surface of the heating iron a, and the heating iron a is tilted in a desired direction. The operating point of the key switch 3 during a predetermined downward stroke of the lock body 1 is adjusted by moving the tongue piece 6 upward or downward.
次で加熱鏝ａを外すとその状態に再び硬化し、以後、鍵
の所定の下動ストロークに対して正確に発音が行なわれ
るようになる。Next, when the heating iron a is removed, it will harden again to that state, and from then on, accurate sound will be produced for a predetermined downward stroke of the key.
このように本考案によるときは、キースイッチ操作部４
に舌片６を形成すると共にその根部に突条７を形成した
ので、該根部を加熱し、該突条７において曲げ力を作用
させることにより舌片６を所望量上動又は下動させるこ
とが出来て錠本体１の所望の下動ストロークにおけるキ
ースイッチの作動点の調速が簡単に行なわれ、而も、鍵
を取外すことなくその調整が出来る効果がある。In this way, according to the present invention, the key switch operating section 4
Since the tongue piece 6 is formed at the same time as the protrusion 7 at the root thereof, the tongue piece 6 can be moved upward or downward by a desired amount by heating the root and applying a bending force to the protrusion 7. As a result, the operating point of the key switch can be easily controlled during the desired downward stroke of the lock body 1, and the adjustment can be effected without removing the key.
