- 押鍵操作により鍵回動軸を中心に回動する鍵と、
前記鍵に対応して設けられ、対応する鍵の押鍵操作により、前記鍵回動軸に平行なハンマ回動軸を中心に回動して押鍵操作に慣性を与えるハンマ体とを有し、
押鍵操作により、前記鍵の一部分または押鍵操作によって可動する介在部材のいずれかが駆動部となって、前記駆動部の押圧駆動面が前記ハンマ体の被駆動部を押圧駆動するように構成された電子鍵盤装置であって、
前記駆動部の前記押圧駆動面と前記被駆動部とは、前記鍵及び前記ハンマ体が回動するときに分離し得るように構成され、
前記駆動部には、前記ハンマ回動軸の側に開口し、前記被駆動部と係合するスリット部が設けられ、
前記スリット部の天井部と底部のそれぞれに緩衝材が設けられ、
前記スリット部の前記天井部に設けられた緩衝材の下面が、前記押圧駆動面となり、
前記押圧駆動面は下方に凸の曲面であることを特徴とする電子鍵盤装置。 - 強押鍵で押鍵した場合は、前記押圧駆動面と前記被駆動部とが分離し得、弱押鍵で押鍵した場合は、前記押圧駆動面と前記被駆動部とが押鍵往行程の全てで当接関係となることを特徴とする請求項1記載の電子鍵盤装置。
