<p><P>PROBLEM TO BE SOLVED: To provide a driving mechanism for flipping a sounding piece with a free end part to be displaced, which is easy to produce, and which is comfortably operated. <P>SOLUTION: The mechanism comprises a sounding piece 3 for generating sound when the free-end part is flipped; a jack 5 in which a driving pin 5b for flipping the sounding piece is provided; a wippen 4 by which the jack supported so as to be rotated is moved to a B direction, in such a way that the driving pin displaces the sounding piece; a keyboard 6 for transmitting operation force of a user to the wippen; and a restriction piece 1k by which the driving pin is escaped to outside of the sounding piece free end part, by rotating the jack to an E direction, after the sounding piece is displaced to an upper direction. Moreover, an auxiliary reed is provided, together with the corresponding driven sounding piece 3 , and the sound generated is harmonized due to the resonance of the auxiliary reed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
