Supporting construction for keyboard assembly |
摘要 |
A pair of key blocks bearing a keyboard assembly via an intervening frame are pivotally coupled to side boards of a musical instrument by means of pin-groove engagement, and a top board and a front cover of the instrument are both turnable upwards in order to allow free pivotal movement of the keyboard assembly. Pivotal mounting of the keyboard assembly allows easy access to its bottom construction for replacement, repairment and adjustment purposes.
