<P>PROBLEM TO BE SOLVED: To provide a keyboard device in which a key touch feeling approximate to an acoustic piano can be obtained during a keying operation without using a hammer member. <P>SOLUTION: A keyboard device includes: a plurality of key guide units 11 which are provided on a keyboard chassis 2 for guiding a plurality of keys 6 vertically, respectively; a plurality of load imparting members 20 which are provided in the plurality of key guide units 11, respectively, and, when keying operations are performed on the plurality of keys 6, impart loads caused by friction resistance to the keys 6 on which the keying operation have been performed, respectively; and a plurality of load departing units 29 which are provided in the plurality of keys 6, respectively, and, when ending push-down actions of the keys 6 on which the keying operations have been performed, depart the loads imparted to the keys 6 by the load imparting members 20, respectively. Therefore, without using a hammer member, a key touch can surely be made heavy by imparting the loads to the keys 6 during keying operations, and key touch feelings releasing the key loads can be obtained by rapidly lightening the key loads through the load departing units 29, so that playability can be improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
