ABSTRACT:
An apparatus for attaching a pair of fastener elements of a garment fastener to a garment fabric, comprises an optical indicator for designating a position of the garment fabric where the two fastener elements are to be attached. The indicator includes a light projector having a light source for projecting a beam of light, a reflector for reflecting the light beam downwardly, and means defining an aperture for the passage therethrough of the reflected light beam. An actuator is operatively connected to the light projector for reciprocating the same toward and away from a position where the aperture is in registry with a common vertical axis of the two fastener elements. The indicator is structurally and functionally separated from a pusher mechanism for supplying one fastener element to an upper unit of the apparatus. The indicator may include means for changing the color of the light beam projected from the light source so that a clear and distinctive light spot is produced on the garment fabric even when the latter has a color the same as or confusingly similar to the color of the light beam.
