Abstract: In a multiple-time recorder in which different colored recordings are superimposed on a single sheet to draw a multi-colored drawing, the reference position of the recording paper must remain at a same point for each-time drawing of a single color. At an initialization, a physical property of the recording paper is measured as a function of the paper position including the reference position, and this function is stored in a reference data memory. Before the commencement of the next and subsequent recordings, the same physical property is measured and stored in a compared data memory. From the cross correlation of the contents of the compared data memory and those of the reference data memory, the reference position for the next and subsequent recordings is precisely determined.
