摘要： To provide a switch structure that ensures a smooth parallel movement of a pressing operation portion with a simple configuration and suppresses deterioration in appearance. A guided portion 41A and a guided portion 43A are provided in an operation switch 40 at different positions in a circumferential direction, and restriction portions 21A, 22A facing the guided portion 41A from an outer side and an inner side in the radial direction, and restriction portions 24A, 23A facing the guided portion 43A from the inner side and the outer side in the radial direction are provided in a housing 10. In a pressing process, the guided portion 41A moves while being guided between the restriction portions 21A and 22A, and the guided portion 43A moves while being guided between the restriction portions 24A and 23A. Movement restricting directions of the guided portions 41A, 43A are not parallel to each other.

摘要： A keyboard instrument includes: a detectable portion that is disposed on a movable member that is displaceable in response to a playing operation by a user, a detection board; a control board that is discrete from the detection board; and a wiring portion. The detection board includes a detection coil facing the detectable portion, and a detection circuit that generates a detection signal depending on a distance between the detection coil and the detectable portion. The control board includes a control integrated circuit configured to generate, based on the detection signal, displacement data indicating a position of the movable member. The wiring portion includes a wiring configured to transmit the detection signal from the detection board to the control board.

摘要： The present disclosure provides a generation device having a plurality of operators that receive a user operation that causes generation of a sound. The generation device includes: at least one first operator arranged in a first region and configured to receive a first user operation that causes generation of a rhythm sound signal; at least one second operator arranged in a second region and configured to receive a second user operation that causes generation of a melody sound signal; and at least one third operator arranged in a third region and configured to receive a third user operation that causes a sound effect to be applied to a synthesized sound signal of the generated rhythm sound signal and the generated melody sound signal. The first region, the second region, and the third region are different regions of the generation device from each other.
