Abstract

PURPOSE:To prevent a semiconductor device from contaminating with ink by providing a skirt gradually increased in a bore at the end of a lead supporting cylinder. CONSTITUTION:A skirt 13 is formed at the end of a lead supporting cylinder 2 to absorb excess ink adhering to a lead 1 into the skirt 13 after ink 9 is applied to a semiconductor device 12. Since the bore of the skirt 13 is gradually increased from the midway to the end of the cylinder 2 while the lead is being designated, the ink 9 absorbed into the skirt 13 is returned to a gap between the inner periphery of the cylinder 2 and the outer periphery of the lead 1 and an ink bottle 3 by capillarity. Thus, the ink 9 is prevented from adhering in a spherical state to the end of the outer periphery of the cylinder 2.
