ABSTRACT:
A method of controlling the operation of a copying apparatus which includes a tracer for tracing automatically a contour of a pattern to be copied and a working machine arranged in conjunction with the tracer in a given relationship is disclosed. At first, the tracer is moved manually with respect to the pattern to be traced to detect point data such as a working start point, a copy start point and a copy end point, and then automatically moved along the contour of the pattern to detect pattern data, while the working operation is performed. Next, the thus detected point and pattern data are stored in a cassette tape. Therefore, in case of performing the repetitive working operation for the same pattern, since the working operation can be performed in accordance with the data read out of the cassette tape, the required working operation can be effected in a simple and rapid manner.
