An apparatus for measuring distance between an X-ray generating unit and an image capturing unit of X-ray devices is provided to enhance user convenience by calculating the distance based on reception time difference between electric wave and ultrasonic signals. An apparatus for measuring distance includes a signal generator(30), a calculator(40), and a display unit. The signal generator implemented at an image obtaining unit generates simultaneously electric wave and ultrasonic signals. The calculator implemented at an X-ray generating unit(1) receives the electric wave and ultrasonic signals, and calculates distance the X-ray generating unit and an image capturing unit(4) based on reception time difference between electric wave and ultrasonic signals. The display unit displays the calculated distance.
