Abstract

PURPOSE: To make the relative positions of action mechanisms and keyboard accurate by unitizing striking mechanism and coupling the same to the main unit of a piano.
CONSTITUTION: A key bed 34, keyboard 41, actions 31, etc. are integrally constituted and respective striking mechanisms 51 ... are unitized so that the adjustment of the relative positions of the actions 31 and keyboard assembly 32 in the transverse and parallel directions of strings 16 is surely and readily accomplished by the lateral movements of bar members 37 thru 39 and the movement of a member 36. When these mechanisms 51 ... having undergone the adjustment are determined of the positions with the may bed and key bed 34 by means of positioning pins 65 engaging into bushings and are coupled to the main unit of the piano by using adjusting screws 68, etc., the relative positions of the action mechanism and keyboard are always accurately held and the action touch is made always even.
