Abstract
A phonograph cartridge stylus protector includes a magnifying lens to permit the user to view a magnified image of the stylus tip. The stylus protector is pivotally mounted to the cartridge and may be positioned at a first position out of the way of the stylus, a second position in which the user may obtain one magnified view of the stylus tip while the stylus tip is inserted in a record groove, and a third, lowermost position in which the protector protects the stylus against accidental contact and in which the user may obtain a different magnified view of the stylus tip and the area adjacent the stylus tip.
