Abstract
An apparatus for tracing and recording image lines includes a coordinate reader which detects coordinate values of an image to be traced; an image sensor which is movable in a plane relative to a table; a memory in which image signals detected by means of the sensor are written; and a central processing unit which controls the above elements of the apparatus. Trace data are obtained by means of the coordinate reader which detects coordinate values of the image lines. Then, the image is positioned on the table, where record data are obtained based on the trace data by means of the image sensor which generates image signals corresponding exactly to the image.
