ABSTRACT:
Marking of a generally planar object at a first surface thereof with one or more indentation-defined pixels. For generating the marking, an anvil member is provided as having an impact surface. A marking head is positioned at a fixed relationship with respect to the anvil member. The head includes a confronting portion opposing the impact surface, and a marker pin having a distal impacting tip issuing from the confronting portion which is reciprocatably actuable along a marking axis from a retracted position to an extended position. With the object disposed intermediate the marking head and the anvil member, and with at least a portion of the second surface of the object being supported on the impact surface of the anvil member, the object may be positioned at a predefined pixel location within a marking locus. Thereupon, the impacting tip of the marker pin may actuated from its retracted position to its extended position impacting the second surface of the object in an indentation contact defining one of the pixel marks.
