<P>PROBLEM TO BE SOLVED: To provide a keyboard device capable of enhancing performance by preventing horizontal deflection of a hammer member when a key is depressed, while preventing detachment of the hammer member in the vertical directions. <P>SOLUTION: A hammer contact section 30 is provided at a tip end of the hammer member 3 in which an action weight is given to a key 2 provided so as to be rotatable in vertical directions on a keyboard chassis 1, and a hammer connection section 20, having a holding hole section 31 in which the hammer contact section 30 is inserted so as to be slidable, is provided in the key 2. Guide projection parts 34 and 35 are provided in top and bottom faces of the holding hole section 31, and guide groove sections 36 and 37 for relatively guiding the guide projection sections 34 and 35 in cross directions of the key 2, are provided. Consequently, detachment of the hammer contact section 30 in vertical directions from the key 2, when the key is pressed, and horizontal deflection of the hammer member 3 are prevented, and the action weight by the hammer member 3, according to key pressing operation is accurately transfered to the key 2 and performance is fully enhanced. <P>COPYRIGHT: (C)2008,JPO&INPIT |
