Abstract: <P>PROBLEM TO BE SOLVED: To suppress noise generation and damages to a collided section by collision among a various kinds of members, in key pressing and depressing the operation of a key, according to key information that represents key depressing and key unpressing of the key.  <P>SOLUTION: A computer section 70 reads an event data in a music piece data with the lapse of time and controls the key driving device 50 according to the read event data. In a keyboard device 50, the key is displaced from an original position to a key pressing position with a large force, when key pressing is started, and thereafter, the key is held in the key pressing position with small driving force. When key depressing is started, the driving force of the key is decreased during a key pressing hold operation period, while the driving force of the key is finally released; and thereby, the key is restored in the original position from the key pressing position. In this case, when a key pressing operation is started, the driving force is increased in a stepwise manner; and when key pressing operation control is finished, the driving force is increased. When a key-depressing operation control is started, the driving force of the key is decreased rapidly, and thereafter, the driving force is increased.  <P>COPYRIGHT: (C)2009,JPO&INPIT
