Elliptical vibration machines can transport works in multiple directions by varying the phase difference between vertical and horizontal vibration. Works have a phase difference with zero velocity. The phase difference with zero velocity change based on a work's friction coefficients. Utilizing this characteristic, electronic parts with different friction coefficients of the face side and the reverse side can be separated. If the given vertical vibration is over jumping limit, the phase differences with zero velocity of the face side of electronic parts change drastically. As a result, the margin between the two phase differences with zero velocity widens and electronic parts can be separated face/reverse side quickly. In this investigation, we observe the movement of electronic parts using a high-speed camera and search for the reason that the phase differences with zero velocity change.
