Abstract: A keyboard device includes at least one key and an action mechanism corresponding to the at least one key. The action mechanism includes a transmitter which moves in response to key depression to the at least one key, a hammer member which operates, in response to movement of the transmitter, to apply a load to the depressed key, a first abutting part which is arranged on one of the hammer member and a member which the hammer member abuts, and an elastic part which is arranged on another of the hammer member and the member which the hammer member abuts. At least one part of the elastic part gets over the first abutting part in a process of deforming of the elastic part, thereby a let-off feeling is given to the depressed key.

Abstract: A keyboard apparatus is provided, which is provided with plural keys 2 disposed in parallel, plural transmission members 10 rotating in response to a key pressing operation on the plural keys, and plural hammer members 11 rotating in accordance with rotation of the transmission member to give an action load to the key. The weights of the transmission members together with the weights of the hammer members bring the plural keys to the initial positions and initial loads of the keys are adjusted by the weights of the hammer members. Even if the weight of the hammer member is changed, the initial load of the key can be adjusted based on the weight of the transmission member. Therefore, when the weights of the hammer members are changed, the initial loads of the keys can be kept constant on the high-pitched tone side and the low-pitched tone side.
