Abstract
To provide an electronic wind instrument capable of accurately detecting the amount of rotation of a transmission member. An electronic wind instrument whereby contact with an optical sensor by a flat surface of a rear section can be suppressed even when at least a prescribed amount of a reed is bitten, as a result of the flat surface rotating in a direction away from the optical sensor when the rear section of the transmission member rotates in conjunction with displacement of the reed. As a result, the spacing between the facing flat surface and the optical sensor can be set comparatively narrowly in the initial state and the detection sensitivity at the optical sensor increased, thereby enabling accurate detection of the rotation amount of the transmission member (the amount of the reed that is bitten).
