生部を設けたので、棒状体の傾きを求めることができる
ため、この棒状体の傾きも入力データとして利用できる
という格別の効果を達成することができる。In addition, since multiple ultrasonic generators are provided at different positions along the length of the rod, the inclination of the rod can be determined, which has the special effect of allowing the inclination of the rod to be used as input data. can be achieved.
