産業上の利用分野
本発明は電子オルガン、電子ピアノ等の各種電
子楽器に使用する鍵盤装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a keyboard device used in various electronic musical instruments such as electronic organs and electronic pianos.
従来例の構成とその問題点
一般に電子楽器において鍵盤装置は第１図、第
２図に示すほうに構成されていることが多い、第
１図、第２図において鍵盤１の後方には各種操作
釦３やこの操作釦３によつて操作されるスイツチ

に一体に形成した支持片６ａで回動自在に支点支
持されている。そして鍵盤１は更にスプリング７
によつて常時上方に付勢されており、鍵盤を下方
に押圧したとき、シヤーシ６に取付けられたスイ
ツチ８が押圧操作されるように構成されている。Conventional configurations and their problems In general, keyboard devices in electronic musical instruments are often configured as shown in Figures 1 and 2. In Figures 1 and 2, various operations are provided behind the keyboard 1. A panel 2 is arranged to which a button 3, a switch 4 operated by the operation button 3, a printed wiring board 5, etc. are attached, and a rear end of the upper surface of the keyboard 1 is connected to a chassis 6.
It is rotatably supported as a fulcrum by a support piece 6a integrally formed with the support piece 6a. And keyboard 1 is further spring 7
The switch 8 attached to the chassis 6 is pressed upward when the keyboard is pressed downward.
ところで、このように構成された鍵盤装置では
パネル２と鍵盤１との間に寸法Ａの隙間をあけて
おくのが通例であり、この寸法Ａはパネル２の下
側への反りや鍵盤１とパネル２との取付精度等を
考慮して決定されている。すなわち、寸法Ａを大
きくとると内部が見えて見栄えが悪くなり、小さ
くとるとパネル２が下側に反つたときパネル２が
鍵盤１に当り押圧された鍵盤１が元に戻るとき、
異音を発することがあり、その寸法の設定が非常
にむつかしいという問題があつた。 By the way, in a keyboard device configured in this way, it is customary to leave a gap of dimension A between panel 2 and keyboard 1. It is determined in consideration of the mounting accuracy with the panel 2, etc. In other words, if the dimension A is set too large, the inside will be visible and the appearance will be bad, and if it is set too small, when the panel 2 is warped downward, the panel 2 will hit the keyboard 1 and the pressed keyboard 1 will return to its original position.
There were problems in that it could make strange noises and that it was very difficult to set its dimensions.
発明の目的
本発明はこのような従来の欠点を除去するもの
であり、簡単な構成で製造、組立ての容易な優れ
た鍵盤装置を提供するものである。OBJECTS OF THE INVENTION The present invention eliminates these conventional drawbacks and provides an excellent keyboard device that has a simple structure and is easy to manufacture and assemble.
発明の構成
本発明は鍵盤の上面後端部を支点支持する支持
片に直接パネルの前端面を当接させるように構成
したものであり、本発明によればパネルが下側に
反つてもこれを支持片によつて阻止することがで
き、見栄えよく、しかも鍵盤操作に支障のない優
れた鍵盤装置を得ることができる。Structure of the Invention The present invention is configured such that the front end surface of the panel is brought into direct contact with a support piece that supports the rear end of the upper surface of the keyboard as a fulcrum.According to the present invention, even if the panel curves downward, this This can be prevented by the support piece, and it is possible to obtain an excellent keyboard device that has a good appearance and does not interfere with keyboard operation.
実施例の説明
第３図は本発明の鍵盤装置の一実施例の断側面
図であり、図中第１図、第２図と同一符号を付し
たものは第１図、第２図と同一のものを示してい
る。DESCRIPTION OF EMBODIMENTS FIG. 3 is a cross-sectional side view of an embodiment of the keyboard device of the present invention, and the same reference numerals as in FIGS. 1 and 2 in the figure are the same as in FIGS. 1 and 2. It shows things.
第３図において、第１図、第２図と異なる点は
シヤーシ６に一体に形成された支持片６ａが鍵盤
１の上面より寸法Ｂだけ上方に突出するように構
成されており、その上、この支持片６ａに直接パ
ネル２の前端面が当接するように上記パネル２を
配置している点である。 3 is different from FIGS. 1 and 2 in that a support piece 6a integrally formed on the chassis 6 is configured to protrude upward by a dimension B from the top surface of the keyboard 1, and in addition, The above-mentioned panel 2 is arranged so that the front end surface of the panel 2 directly contacts this support piece 6a.
このように構成するとパネル２の下側へ反りを
シヤーシ６に一体に形成した支持片６ａによつて
ほゞ完全に防ぐことができ、したがつて寸法Ｂは
寸法Ａに比し著しく小さくすることができ見栄え
も同時に著しく良好なものにすることができる。
そして、上記実施例によれば寸法Ｂが小さくなつ
てもパネル２に鍵盤が当るようなことは全くな
く、これによる異音の発生も全く生じないという
利点を有する。 With this configuration, downward warping of the panel 2 can be almost completely prevented by the supporting piece 6a formed integrally with the chassis 6, and therefore the dimension B can be made significantly smaller than the dimension A. At the same time, the appearance can be made extremely good.
The above embodiment has the advantage that even if the dimension B is reduced, the keyboard will never hit the panel 2, and no abnormal noise will be generated due to this.
発明の効果
本発明は上記実施例より明らかなように鍵盤の
後端部を支点支持する支持片を鍵盤の上面より若
干上方に突出させ、ここに直接パネルの前端面が
当接するように構成したものであり、パネルの下
側への反りを効果的に防止することができると共
に全体として見栄えのよいものとすることがで

も従来に比し、著しく粗でよく、その製造、組立
ても著しく容易になるという利点を有する。Effects of the Invention As is clear from the above embodiments, the present invention has a structure in which a support piece that supports the rear end of the keyboard as a fulcrum protrudes slightly above the top surface of the keyboard, so that the front end surface of the panel comes into direct contact with the support piece. It is possible to effectively prevent the panel from warping downward, and it can be made to look good as a whole.Furthermore, it can also prevent the generation of abnormal noise, and the dimensional accuracy is also higher than before. Compared to this, it has the advantage that it can be much rougher and its manufacture and assembly are much easier.
