Abstract
A reciprocating rod of the ejector is borne in a non-sliding state by permanent magnets on the reciprocating rod and permanent magnets surrounding the reciprocating rod. The reciprocating rod linearly projects out and retracts by the reciprocating components which cause the reciprocating rod to reciprocate by the driving signals from the driver circuit. A slanted surface is provided at the foremost end of the reciprocating rod. When the granular objects to be ejected flow-in continuously, the projecting-out action takes place correspondingly with the leading granular object to be ejected and, after the following granular object(s) to be ejected has been ejected, the retracting action takes place.
