A conveying device includes a sheet conveyor configured to convey a medium in a conveyance direction of the medium, a sheet winder including a winding roller and a winding motor, and circuitry to control the sheet conveyor and the sheet winder. The circuitry is configured to convey the medium intermittently while repeating: causing the sheet conveyor and the sheet winder to convey the loosened medium by a predetermined conveyance amount; rotating the winding motor in a normal direction by a predetermined torque according to an outer winding diameter of the medium to apply a predetermined tension force to the medium; and rotating the winding motor in a reverse direction to loosen the medium by a predetermined slack amount. The circuitry is configured to determine the predetermined tension force according to the width of the medium intersecting with the conveyance direction of the medium.

A winding device (10) for winding a web (92) onto a reel (90) has a drive shaft (20), a gear (30), a clutch shaft (63), an energy storage means (50), a clutch (60) and an output shaft (80). The gear (30) is configured, as a positive-engagement gear, to transmit a rotary movement of the drive shaft (20) to a first clutch shaft element (61) assigned to the clutch shaft (63). The clutch shaft (63) is connected via the clutch (60) with the output shaft (80) in order, selectively, to enable or prevent a transmission of torque between the clutch shaft (63) and the output shaft (80). The gear (30) has, without the energy storage means (50) having effect, a first predetermined transmission ratio (i_0) between the drive shaft (20) and the clutch shaft (63), and the energy storage means (50) is configured to store and release rotational energy and to vary the transmission ratio.
