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.
Claims18
A keyboard device comprising:
- at least one key;
- and
- an action mechanism corresponding to the at least one key, wherein the action mechanism comprises:
- 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,
- wherein 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.
A keyboard device comprising:
- at least one key;
- and
- an action mechanism corresponding to the at least one key, wherein the action mechanism comprises:
- a transmitter which moves in response to key depression to the at least key;
- and
- a hammer member which adds weight to the depressed key by moving in response to the transmitter and on which an elastic deformer is arranged,
- wherein a let-off feeling is given to the depressed key when a first abutting part which abuts the elastic deformer causes the elastic deformer to elastically deform.
