    摘要: An operation-position detector and an application thereof are configured to include a tube that allows an ultrasonic signal to propagate therethrough and to detect the operation position of an operation of an operator without the use of an electric switch.
    A tube (40) has a plurality of holes (41 a to 41 e) capable of being selectively closed or opened by an operation of an operator at its side and is provided with an ultrasonic transmitter-receiver (50) arranged at a first end thereof. A signal processor (60) drives the ultrasonic transmitter-receiver (50) and causes an ultrasonic signal to propagate through the inside of the tube (40), receives a reflection signal corresponding to a closed or open state of each of the holes (41 a to 41 e), and detects the state of each hole on the basis of the reflection signal, thereby detecting the operation position of an operation conducted by the operator.
