ULTRASONIC PROBE AND ULTRASONOGRAPH

摘要

PROBLEM TO BE SOLVED: To provide a cordless ultrasonic probe having no exposed electric contact point, and having high reliability and safety. SOLUTION: Electromotive force is generated in a coil wound on a magnetic core from the outside by electromagnetic induction by the cordless ultrasonic probe 100 for internally storing an ultrasonic wave transmitting receiving means operating with a secondary battery as a power source, and the built-in secondary battery 114 is charged with generated electric power. The probe has a display means for displaying a residual quantity of the secondary battery.
