WEB CONVEYING DEVICE, PRINTING APPARATUS, AND TENSION CONTROL METHOD |
摘要 |
A control unit allows a rotational position of a tension generating roller to be changed depending on a width of a web at time of the beginning of conveyance of the web, controls a motor according to a detection signal of a second sensor such that a tension guide maintains its position within a predetermined range during conveyance of the web, causes position data at time of keeping the same value of the position data of the motor for a predetermined period to be stored, calculates an initial operational position of the tension generating roller using the position data and a predetermined correction coefficient, and sets the calculated initial operational position as an initial operational position of the tension generating roller at time of the beginning of next conveyance of web.
