えたビブラフォンのファン停止角度を規制するビブラフ
ォンのファン停止角度制御装置において、ファンの回転
角度が所定値になる度に検出信号を発生する角度検出回
路と、電流を遮断したとき回転が直ちに停止する回転速
度となるための補助電流をモータに供給するとともに、
検出信号が発生する度に補助電流を遮断する駆動回路と

度制御装置。A vibraphone fan stop angle control device that regulates the fan stop angle of a vibraphone equipped with a vibrato mechanism that rotates a fan using a motor includes an angle detection circuit that generates a detection signal every time the rotation angle of the fan reaches a predetermined value, and an electric current. In addition to supplying an auxiliary current to the motor to achieve a rotation speed that immediately stops rotation when the motor is cut off,
A fan stop angle control device for a vibraphone, comprising a drive circuit that cuts off an auxiliary current every time a detection signal is generated.
