Title: Musical sound control signal generating device for electronic musical instrument
Inventor: MASUBUCHI TAKAMICHI
IPC: G10H1/34
Filed: 1993-12-27
Abstract: PURPOSE:To improve response and to make detection sensitivity irrelevant to a key array direction. CONSTITUTION:The base part 8a of a stopper member 8 is fixed to the reverse surface of a keyboard frame 2 which supports keys 1 in a free swing state, a stopper part 8d which extends in the key array direction is integrally formed at the base part 8a through beams 8b and 8c along the key length direction and has a lower-limit stopper 9 stuck on the top surface, and strain sensors 11A and 11B are arranged on the beams 8b and 8c closely to the base part 8a. When a key stopper piece presses the stopper part 8d through the low-limit stopper 9 by an after-touch after key depression, the sum of forces operating on two fixed points P1 and P2 of the stopper part 8d on the prolongations of the beams 8b and 8c is constant irrelevantly to the key depression position in the key array direction, so an after-control signal with good response can be generated with the sum of the outputs of the strain sensors 11A and 11B positioned on curvature points on the beams 8b and 8c.
