<P>PROBLEM TO BE SOLVED: To provide a keyboard device which stabilizes rotating operation of a key to allow satisfactory key depressing operation by fixedly holding a rotation support point of the key whichever of a front portion and a rear portion of the key is depressed, to secure the durability of a bent portion. <P>SOLUTION: The keyboard device includes: a keyboard chassis 1; a key 2 which is arranged on the keyboard chassis 1 and is rotated in a vertical direction by bend of a bent portion 22 located in the rear portion thereof; and a key rotation holding part 30 for fixedly holding the rotation support point of the key when the key 2 is rotated in the vertical direction. Consequently, when the key is depressed to bend the bent portion 22 of the key 2 in the vertical direction, the rotation support point of the key 2 is fixedly held by first and second support parts 31 and 32 of the key rotation holding part 30, so that the key 2 can be always rotated in a fixed state. Therefore, whichever of the front portion and the rear portion of the key 2 is depressed, the durability of the bent portion 22 can be enhanced and the rotating operation of the key 2 can be always stabilized, so that satisfactory key depressing operation of the key 2 can be performed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
