PURPOSE: A height measuring apparatus and height data management system using the same are provided to minimize contamination due to foreign materials or damage due to an external shock by arranging a radio signal transfer part in a hollow part of a supporter.CONSTITUTION: A supporter(110) includes a hollow part which is formed inside thereof. A touch bar(120) is arranged at the supporter to move up and down. A driving control part(130) controls the driving of the touch bar. A touch detection part(140) senses the contacting state of a target person and the touch bar. A height extension part(150) calculates the height of the target person using a sensing value in the touch detection part. A radio signal transfer part(160) transfers the sensing value of the touch detection part to the height extension part in a wireless system. A display part displays the height calculated in the height extension unit.COPYRIGHT KIPO 2013본 발명의 실시예는 신장측정장치에 관한 것으로써, 터치바와 피측정자의 접촉 신호를 무선 방식으로 신장연산부에 전달할 수 있고, 유선 방식으로 신호를 전달하기 위한 구성요소를 생략할 수 있다.
