PROBLEM TO BE SOLVED: To avoid damage and breakage of articles by receiving a shock to only a limited part, by moving the articles in a tray for counting furnished with numerous compartments for counting the articles. SOLUTION: In this counter, an elliptical vibration is applied to a movable plate 7 attached with a tray 1 for counting by an electromagnet 21 for horizontal vibration, a leaf spring 24 for horizontal vibration, an electromagnet 31 for vertical vibration and a leaf spring for vertical vibration the ceramic dielectrics in the tray 1 for counting are moved in the circumferential direction to fit to the compartments for counting. In this case, a phase difference reversing timer is added to the phase setter of the control system of a driving part 8, the rotating direction of the elliptical vibration is reversed, and the moving direction of the ceramic dielectrics in the tray 1 for counting is reversed in the clockwise direction and the counterclockwise direction at a specific time interval.
