<P>PROBLEM TO BE SOLVED: To provide a cover opening/closing structure of a keyboard instrument, which is capable of surely stopping a cover of the keyboard instrument in an opening position to control the position and attitude of the cover in the opening state, with a simple configuration having a reduced number of components. <P>SOLUTION: A coupling mechanism 30 coupling a side part 6 of a case and an end part of a cover 20 facing the side part 6 includes a long-sized tabular coupling tool 31 which has one end supported at a first link fulcrum provided on the side part 6 and has the other end 31b supported at a second link fulcrum 35 provided on the end part of the cover 20. Further, a stopper mechanism 37 is provided which brings a part in the vicinity of the second link fulcrum 35 of the coupling tool 31 into contact with an attachment plate 34 attached to an inner surface 20c of the cover 20 in a state where the cover 20 is in the opening position, to not only stop turning of the cover 20 in this position but also control the position and attitude of the cover 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
