A body height measuring apparatus is disclosed comprising a measuring bar, a ground mainframe, an ultrasound signal transmit unit and an ultrasound signal receive unit, a synchronous signal transmit unit and a synchronous signal receive unit. The first operational control unit and a second operational control unit synchronize the operation of the ultrasound signal transmit unit and the ultrasound signal receive unit through manipulation of the synchronous signal transmit unit and the synchronous signal receive unit, and calculate a height based on a transmission time during which an ultrasound signal travels from the ultrasound signal transmit unit to the ultrasound signal receive unit. As the body height is measured based on a unidirectional transmission of the ultrasound signal, the measurement error is reduced, the measuring accuracy is improved and an advantage in use is achieved. |
