Claim Text:
1. A static eliminator for a parts feeder comprising: a bowl to which vibration is applied for moving works on a surface of the bowl, having a static eliminator cup of which a bottom portion thereof is opened in a downward direction toward said surface of said bowl and being separated from said surface by a distance sufficient for allowing said works to pass through, said static eliminator cup being provided, in a center part of a top wall of an upper portion thereof, with an ion generating chamber for ionizing air introduced from outside to be ionized air and an ionized air injection opening through said top wall into the upper portion of the static eliminator cup, said ionized air being sucked by negative pressure in said static eliminator cup into said static eliminator cup, said static eliminator cup being further provided with, at opposites sides of an upper portion on an inner side wall thereof below said ionized air injection opening, a pair of air injection openings for injecting air into said static eliminator cup directed in a diagonally downward tangential direction for injecting air into said eliminator cup in a diagonally downward tangential direction along said inner side wall of said static eliminator cup so as to generate a downwardly circling cyclone flow of air within said inner side wall of said static eliminator cup, and a negative pressure of air at said upper portion caused by centrifugal force of said cyclone and an upwardly circling tornado flow of air caused by said negative pressure.
