PROBLEM TO BE SOLVED: To solve the problems of causing winding deviation in a wound recording medium if deviation occurs in the direction of crossing a conveyance direction in the case of winding up the recording medium, and of remarkably causing a deviation in the direction of crossing the conveyance direction to increase the winding deviation if a winding up error occurs to bring the recording medium into contact with a floor in an image recorder using the recording medium that is wound up in the shape of a roll and including a winding device for winding a recorded recording medium in the shape of a roll.SOLUTION: Sagging is created by self-weight in a recorded recording medium to acquire tension equal to or greater than a prescribed amount by making the sagging smaller than a prescribed sagging amount. When tension increases, a winding deviation is suppressed. By using a sensor for detecting an interval between a roll obtained by winding the recorded recording medium and a regulation bar, and a bottom edge of the sagging, and a winding device, the winding device is controlled so as to make the sagging to be a prescribed sagging amount. |
