摘要： A keyboard device for a keyboard instrument, capable of obtaining excellent touch feeling and stable key stroke without giving sponge feeling or unpleasant vibration during key depression. The keyboard device includes a keyboard chassis, keys pivotally supported on the chassis, hammers swingably supported on the chassis and swinging along with key depression, a hammer upper limit stopper provided on a chassis rear end and contacted by a hammer rear end from below during key depression, and a key lower limit stopper provided on a chassis front end and contacted by front ends of the keys from above during key depression. The hammer upper limit stopper has predetermined flexibility that allows deformation of the hammer upper limit stopper such that after contact of a hammer during key depression, an associated key reaches its lowest position in a state in contact with the key lower limit stopper.

摘要： A piano frame including a main plate having a first major surface for supporting piano strings and an opposite second major surface for supporting a soundboard. First, second, third and fourth elongate anchor zones are located on the first major surface for anchoring, respectively, first end (upper, tuneable end) and second end (lower, hitched end) of bass strings and first end (upper, tuneable end) and second end (lower, hitched end) of treble strings. A plurality of openings are provided in the main plate between the third anchor zone and the fourth anchor zone. A truss defined by a plurality bracing members integrally formed in the main plate extends between the third anchor zone and the fourth anchor zone. The bracing members are located wholly between a plane extending between the third and fourth anchor zones and a plane defined by the second major surface of the main plate.

摘要： A keyboard-type tone plate percussion instrument which is simple in construction and light in weight and capable of easily unifying key-operation feelings and efficiently outputting well-balanced sounds. Percussion units are arranged to respectively correspond to keys and tone plates and each strike a corresponding tone plate when driven by a key depressing operation. A resonance box has resonance chambers corresponding to the tone plates and each having an opening side thereof close to a corresponding tone plate. The tone plates are constructed into a single-stage structure where they are arranged in an order of tone pitch in a direction of array of the keys so that tone plates neighboring in specific tone pitch are arranged adjacent to each other. The percussion units are constructed into a single-stage structure where they are arranged to correspond to array of the tone plates.
