Abstract

PURPOSE: To enable guiding to be continuously accomplished without stopping the tracer by marking the conditions under which what branch line is to be selected and traced may be correctly determined to a template in the tracer.
CONSTITUTION: Until a tracer 1 reaches the cutting start point 0, there is only the lead line X and here is no intervention of a branch line, and therefore the photoelectric transducers A, B travel on the center of the line X as shown by the imaginary lines. When the tracer approaches to the start point 0, the element A approaches to the lead line X1 for leading to the cutting start point 01 (shown on the imaginary line product pattern 10) of the next process and detects this. Hence, the DC output of the element A increases fundamentally, trying to rotate the tracer 11 in the left side of the advance direction. In order to correct this turning action, an equivalent length segment Y is provided. This causes the DC output of the other photoelectric transducer B to increase correspondingly and become equal to the DC output of the element A. Hence, the turning movement of the tracer 11 is erased and the tracer passes the center on the line X and arrives at the start point 0.
