Title: Apparatus for melting a needle using an electric current

Abstract: A needle disposal apparatus for melting a needle to be disposed of by passage of electrical current through it, has a guide member having an inlet which permits the needle to be inserted; an upper electrode roller, to which a first voltage is applied, the inserted needle making contact with an outer surface of the upper electrode roller; a lower electrode roller to which a second voltage is applied, the inserted needle making contact with an outer surface of the lower electrode roller; and a drive mechanism which rotates the electrode rollers in each direction so that the inserted needle is drawn between the electrode rollers; wherein the electrode rollers are disposed so that a part of the lower electrode roller is hidden behind the upper electrode roller when viewed from the inlet in a direction of insertion of the needle.
