<P>PROBLEM TO BE SOLVED: To faithfully play a broad range of playing data with good pronunciation. <P>SOLUTION: Annular members 152 and annular spacers 101 composed of elastic members are alternately inserted and arrayed to a revolving shaft 100 and are rotated counterclockwise at all times. When an arm 43 is rotationally moved upward by turning on of electricity and the rotation restriction of a pick 46 is released, the pick 46 rotates instantaneously clockwise. A driving pawl 46a 1 is then fitted between the two annular members 152 opposing each other, and is elastically held and driven, by which the pick 46 is rotated clockwise cooperatively with the annular members 152. As a result, the driving pawl 46a 1 is driven and the driving pawl 46a 4 preceding in the rotating direction pricks a front end of a lead 48 and thereafter the further preceding driving pawl 46a 3 rapidly abuts on a free end 43a of the swing arm 43 and is reset to an initial state, by which the pronunciation action of one time is completed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
