Abstract
A marking device includes a marking mechanism, a marking portion moving mechanism, and a pressure adjusting circuit. The marking mechanism marks a surface to be processed, of an object to be marked, by reciprocating a marking portion. The marking portion moving mechanism moves the marking portion in two-dimensional directions along the surface to be processed. The pressure adjusting circuit keeps a constant pressure which the marking portion applies to the surface to be processed. The marking mechanism includes a cam mechanism for linearly reciprocating the marking portion by following a cam which is rotated by a driving member.
