To use elliptical vibration, it can separate and transport the work which material and shape is similar at the same time. When the vertical vibration of elliptical vibration is larger than 1.0G, works jump and the characteristics of transportation change considerably. But some works don't jump because negative pressure is caused on contact face. As a result, it is possible to separation and transportation by the presence of jump. However, it is difficult to separate works with little difference and tiny works. In this study, authors try these works by using elliptical vibration which has high frequency of driving frequency. But authors are concerned that transportation velocity of tiny works decrease by using elliptical vibration which has high frequency of driving frequency. So, authors think that to separate and to transport of the works need to take steps to cope with the situation by raising the horizontal acceleration of the elliptical vibration. First, author examined that the influence of driving frequency on jump limit and stability of the separation. Next, authors examined that the influence of driving frequency and horizontal acceleration of elliptical vibration on transportation velocity. Finally, from a result of these examinations, authors choose optimal driving condition of the tiny works with little difference in the face side and reverse side. In this condition, authors try separation and transportation a lot of tiny works at fast and stable using elliptical vibration.
