PURPOSE: To improve the precision of a supply number at a vibration feeder for electronic components such as a condensor or the like, by switching a delivery regulating ring into an intermittent rotation at the time point when a number that is less by a predetermined number than a predetermined lot number, has been counted, and arranging so that the ring may stop after it has supplied a remaining number one by one.

CONSTITUTION: An electro component 9 is transported by means of the rotation of a delivery regulating ring 7, and the number of these electro components are counted by means of a counter 11. And, a command for intermittence is issued to a drive electromagnet which is not shown in the drawing, at the time point when the number of electro components 9 that is less by a predetermined number than a predetermined lot number N, has been counted, and the delivery regulating ring 7 is rotated intermittently. And, the remaining number a of electro components 9 is supplied one by one. And, a vibration feeder is stopped at the time of the supply completion of the predetermined lot number N. As a result, the accurate supply of the necessary kinds of electro components can be accomplished.
