Abstract

A keyboard device for an electronic musical instrument includes a frame, a plurality of keys, a plurality of biasing members, a plurality of weight members, and a position-adjusting unit. The keys are mounted to the frame. Each of the keys has a front operating portion and a rear weight-mounting portion, and is tiltable from a normal rest position to a lower stop position in response to a stroking action at the front operating portion. The biasing members bias the keys toward the normal rest position. The weight members are mounted on the rear weight-mounting portions of the keys, and are movable relative to the front operating portions of the keys. The position-adjusting unit is operable so as to adjust concurrently positions of the weight members relative to the front operating portions of the keys.
