Abstract
A keyboard-type tone plate percussion instrument that permits a player to make an operation to select percussion unit's striking a tone plate with or without intervention of a displacement member between percussion units and tone plates, making it possible to change, with a simple construction, tone color produced by a struck tone plate. In response to key depression, a corresponding percussion unit () is driven. The percussion unit directly strikes a corresponding tone plate when a displacement member (), which is different in material and hardness from percussion units, is extracted from between keys and the percussion units, but indirectly strikes the tone plate via the displacement member when the displacement member is interposed therebetween.
