A printing apparatus includes a transport unit configured to transport a medium, a winding unit disposed downstream, in a transport direction, of the transport unit, the winding unit being configured to wind the medium, and a tension applying unit including a rod member biased toward the medium between the transport unit and the winding unit, the rod member being for applying a tension to the medium. The tension applying unit is configured so that the rod member moves along a predetermined direction as at least one of the transport unit and the winding unit is driven to transport the medium. An upper limit position of a movement of the tension bar along the predetermined axis is changed according to a winding mode of the winding unit.

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.

A control device includes a processor configured to: acquire information on a direction in which continuous paper is wound up, specify a viewable surface, which is a surface of the continuous paper viewable from a user in a state where the continuous paper has been wound up, on a basis of the direction in which the continuous paper is wound up, and control a printer to print print information, which is information on a job printed on the continuous paper, on the viewable surface.

The printer has a closed state where the printing head portion and the damper portion are positioned on a position printable on the print mediums, and an open state where the printing head portion and the damper portion are positioned on a position separated from the print mediums. In a case of a transition from the closed state to the open state, the printing head portion and the damper portion behave in conjunction, and in a case of a transition from the open state to the closed state, the damper portion and the printing head portion independently behave.

Disclosed is a label printer, configured to hold the carrier tape with the labels in contact with the printhead, wherein the carrier tape is led between the printhead and a counter-element; a drive mechanism for the carrier tape having a driven carrier tape drawing roller; and at least one non-driven carrier tape pressure roller, associated with the carrier tape drawing roller, that is rotatable about a rotational axis, wherein the carrier tape is led between the carrier tape drawing roller and the respective carrier tape pressure roller and is transported along a predefined carrier tape transport path. The respective carrier tape pressure roller is supported perpendicular to its rotational axis and in a displacement direction toward the carrier tape drawing roller, with a spring device being provided to exert a pressing force onto the carrier tape, said spring device preloading the respective carrier tape pressure roller in the displacement direction.

In accordance with an embodiment, a printer comprises a housing section configured to accommodate a roll body obtained by winding an elongated image receiving medium in a roll shape; a conveyance section configured to pull out the image receiving medium from the roll body to convey it; a printing section configured to perform printing on the image receiving medium pulled out of the roll body by the conveyance section; and a buffer device arranged at the bottom of the housing section on an upstream side of the conveyance section along a direction in which the image receiving medium is pulled out by the conveyance direction so as to apply a pressing force in a direction towards the roll body to the image receiving medium pulled out of the roll body.

A recording device includes a recording unit capable of performing recording on a medium, a holding unit capable of holding a roll body around which the medium is wound, a transporting unit that transports the medium unwound from the roll body, a tension roller that, between the holding unit and the recording unit, comes into contact with a back surface of the medium and applies tension to the medium, and a blowing unit that blows air onto a front surface of the medium. The blowing unit blows the air towards the tension roller.

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.

A recording device includes a recording unit configured to perform recording on a first surface of a medium, a holding unit configured to hold a roll body obtained by rolling the medium, a transport unit configured to transport the medium unwound from the roll body, and a knocking unit configured to knock on a second surface of the medium between the holding unit and the recording unit, the second surface being a surface opposite the first surface. The knocking unit knocks on the second surface by moving between a spaced position for being spaced apart from the second surface and a contact position for making contact with the second surface.

A sheet conveyor includes: a holder that detachably holds a sheet roll; a rotation measuring device that measures a rotation amount of the sheet roll; a conveyance roller that conveys a sheet pulled out from the sheet roll held by the holder; a tensioner that is provided between the holder and the conveyance roller and that contacts with the sheet pulled out from the sheet roll toward the conveyance roller; a position detector that detects a position of the tensioner; a motor that generates driving force for rotating the conveyance roller; and a controller that controls the motor. The controller estimates a diameter of the sheet roll based on a conveyance amount of the sheet caused by rotation of the conveyance roller, a rotation amount of the sheet roll measured by the rotation measuring device, and a position of the tensioner detected by the position detector.
