Abstract

See full text

Provided is a keyboard device for which the number of parts can be reduced. The present invention is provided with: hammers rotatably linked to a chassis; keys rotatably linked to the hammer thereof; guiding pins provided to the keys and extending in the widthwise direction of the keys; and a guiding groove provided to the chassis side and into which the guiding pins are inserted. The downward displacement of the front-end sides of the keys is guided by the rotation of the hammers with respect to the chassis, and the downward displacement of rear-end parts of the keys is guided by the sliding of the guiding pins with respect to the guiding groove. This eliminates the need for links to guide the displacement of the rear-end parts of the keys, thus allowing the number of parts to be reduced.
