摘要： During a tracing operation of a tracer head (TR) the present position of the tracer head in the Z-axis direction is detected and a maximum value (Zma) of the detected tracer head positions is stored in a memory means (AR). When the tracer head (TR) is returned from a trace terminating end (LX2) to a trace starting end (LX1), it is quickly returned to a position (Zma + a) corresponding to the sum of the stored maximum value (Zma) and a constant value (a).
