Abstract
A control device for preventing meandering of patterns for use in a patterned film manufacturing device which includes a film transferring equipment and a pattern forming equipment, includes a marking unit that forms markings on a predetermined reference position on the film, a recognizing unit that is located at the rear of the marking unit and recognizes positions of the markings on the film, a computing unit that computes an amount of meandering based on differences between the reference position and the recognized positions of the markings, a control unit that generates a correction signal for correcting positions of the marking unit and the pattern forming equipment corresponding to the computed the amount of meandering, and a correction unit that receives the correction signal and corrects positions of the marking unit and the pattern forming equipment based on the received correction signal.
