摘要： An operation detection device for a key operation of a keyboard device includes a conductive unit configured to be disposed on each of keys, a substrate configured to be disposed facing each of the keys in a pressing direction of the keys. The substrate is provided with a sensor including at least first and second coils, the sensor being configured to be disposed spaced from one key so that at least one of the first or second coil outputs a signal corresponding to a distance between the one key and the respective sensor. The operation detection device includes a detection unit configured to detect a displacement of the one key in at least one of a yaw direction or a roll direction based on signals output from the first and second coils during a key pressing stroke of the one key.

摘要： A keyboard device includes plural white and black keys 11w, 11b that rock according to a key depression/release operation. Positions of key support portions 13w, 13b supporting the plural white and black keys 11b, 11w in the longitudinal direction are set to be different from one another. The keyboard device also includes hammers 16w, 16b that rock with the rocking movement of the plural white and black keys 11w, 11b. The plural white and black keys 11w, 11b include drive units 11w1, 11b1 that drive the hammers 16w, 16b. The drive units 11w1, 11b1 and the pivot centers of the hammers are located on the same straight line extending in the lateral direction. An upper-limit stopper 21 and a lower-limit stopper 20, which restrict the rocking movement of the hammers 16w, 16b, are provided to extend in the lateral direction.
