摘要： The purpose of the present invention is to provide an upright piano action mechanism that improves sound quality relating to dynamic range and the like and facilitates repetition of the same note on the keyboard of the upright piano and any form of key pressing such as repetition and play-ing at half-touch while playing at pianissimo and half touch with the damper pedal depressed. The action mechanism is configured to either reinforce the spring force of a single hammer butt spring or use two hammer butt springs. When using two hammer butt springs, a butt range cord is provided with a twisted part to cause the hook of the two hammer butt springs to be caught by a ring-shaped part at the tip of the twisted part and the twisted part. The action mechanism uses a material with excellent lubricity for a hammer butt skin while reinforcing the elasticity of a jack spring, and is provided with a rubber-based cushion having a protrusion made of an elastic material with a through-hole along the rear surface of a jack stop rail and the front and rear surfaces of a damper stop rail.

摘要： A striking mechanism for a string instrument, such as a piano or a grand piano, comprises, for each string (4), a hammer (3), which, via a power transmission, is brought to strike the string when the associated key in the keyboard of the instrument is depressed. The mechanism furthermore comprises a first and a second check (27; 29) having, respectively, a first and a second check zone (28; 30) for, in mutual engagement, stopping and temporarily retaining the hammer during rebound. On each check zone, a magnetic or magnetizable material (32; 34) is placed, this material generates a magnetic field which causes the hammer during rebound to obtain a much safer and softer braking than is the case in conventional striking mechanisms whereby the risk of the hammer rebounding and striking the string in an unintended repetition strike is eliminated.

摘要： A keyboard device includes a plurality of transmission members (10) which are displaced in response to a depression operation on each of a plurality of keys (2) and a plurality of hammer members (11) each of which provides an action load to a depressed key (2) by performing a rotating motion in response to the displacement of a transmission member (10) corresponding to the depressed key (2). The weight of the transmission member (10) is set in accordance with the formation density of a plurality of ribs (22b, 45b) formed on a transmission body section (22, 45). Therefore, the weight of the transmission member (10) set in accordance with the formation density of the ribs (22b, 45b) can be provided to the key (2) as a static load. As a result of this structure, an initial load on a key (2) can be optimized, and a key depressing force on the key (2) at the time of key depression can be favorably transmitted to the hammer member (11).

摘要： A key actuating system (1) of a keyboard musical instrument is provided which helps quickly push the keys by reducing reaction force with respect to force of pushing the keys during manual operation, and which supports a person having less strength to play the keyboard musical instrument. The key actuating system for a keyboard musical instrument generates a sound when a key (3) is pushed including; a pressure detection sensor (11) detecting a pushing pressure on the key; a status detection sensor (13) detecting a movement status of the key: an actuator (15) actuating the key in a pushing direction of the key; and a control portion (19), when the pressure detection sensor detects the pushing pressure and the status detection sensor detects motion of the key, controls operations of the actuator in order to maintain the detected pressure by the pressure detection sensor at a pressure threshold which is in a range larger than 0 and smaller than a pushing pressure on the key which is necessary for making a sound.
