A winding unit includes a winding roller configured to wind up an elongated medium M that was transported, a cylindrical pressing member that extends along a rotation shaft of the winding roller and that is configured to press the medium M toward the winding roller at a position where the medium M is wound by the winding roller, a cylindrical winding guide member that extends along the rotation shaft of the winding roller, that has a fixed position with respect to the winding roller, and that is configured to guide the medium M to the winding roller before the medium is wound up by the winding roller, and arms that extend in a direction intersecting an extension direction of the pressing member and that are configured to support the pressing member, wherein the arms are configured to pivot about a central shaft of the winding guide member.

Winding device and printing device with a moveable arm

Provided are: a holding unit configured to rotatably hold a roll body on which a medium is wound; a transport unit configured to transport the medium unwound from the roll body; a tension applying unit configured to press the medium between the holding unit and the transport unit to apply tension to the medium; a driving portion configured to provide driving force to the tension applying unit; a control unit configured to control the transport unit and the driving portion; and a detector configured to detect a load applied to the transport unit, and the control unit controls the driving force by the driving portion on the basis of the load detected by the detector to adjust the tension applied to the medium.

Transport device, printing apparatus, and transport controlling method

A medium heating device includes a support portion configured to support a medium being transported, a heating unit configured to heat a medium supported by the support portion, and a detector configured to detect a temperature of the support portion. The support portion includes a metal plate including a first surface as the support face, an end portion of the metal plate is bent toward an opposite side to the first surface, the metal plate is fixed by a fixing portion and a fixing portion next to the fixing portion in a width direction, and a detection position of the detector is set to a position between the mutually adjacent fixing portions in the width direction.

Medium heating device and liquid ejecting device

A transport device includes a transport roller configured to transport a roll paper, a winding unit configured to wind the roll paper transported, a tension applying unit configured to apply tension to the medium between the transport roller and the winding unit, and a control unit configured to control the tension applying unit. The control unit is configured to control the tension applying unit to maintain a state where the tension is released, at least during an acceleration period of rotation of the transport roller within a period in which the transport roller applies a transporting force to the roll paper.

Medium transport device, recording device, and recording method

A medium transport device includes a transport unit configured to transport a medium in a transport direction, a winding unit configured to wind the medium, a tension applying unit configured to apply a tension to the medium between the transport unit and the winding unit, a drive unit configured to drive the tension applying unit, and a controller configured to control the drive unit, in which the controller is configured to control the drive unit such that an application of the tension by the tension applying unit is released at a time when a subsequent transport operation by the transport unit is started after a termination of an winding operation of the medium by the winding unit.
