ABSTRACT:
A paper alignment mechanism for a recorder in which the paper is moved by one or both rollers at the outer edges of the paper along the X axis in accordance with one variable and a stylus is moved across the paper along the Y axis in accordance with another variable, the alignment being achieved by determining the distance between two points on a line parallel to the Y axis and an orientation line on the paper, applying a pivot near one edge of the paper and a force near the other edge, the force being in such direction as to rotate the paper to an aligned position and the relative positions between the pivot and the point of application of the force being such that the paper between them is in tension.
