Abstract
PURPOSE:To minimize the variation of the extent of feed of a plot form and correct skew by providing a position detector of the plot paper and controlling the rotation of a driving roll based on the detected extent of feed and the extent of skew of the plot paper. CONSTITUTION:A plot paper 1 is fed in the direction of an arrow by a driving roll 2. A position detector 6 and a riving control part 7 which receives the detection signal from the detector 6 to drive a step motor are provided just before a recording head 4. The detector 6 reads position detection marks 8 on the paper 1 to output the position detection signal. The control part 7 differentiates the position detection signal to generate pulses at the time of rise and fall of black and counts the time between both pulses and controls the rotative speed of the step motor so that the counted value coincides with a preliminarily set reference value, thereby increasing or reducing the rotative speed of the roll 2 to correct the extent of feed of the form 1. Further, a differential mechanism of the roll 2 is controlled to correct the extent of skew.
