A medium transport apparatus includes a transport section configured to support a medium and transport the medium in a transport direction, and a wrinkle reducing section configured to come into contact with the medium to reduce the formation of wrinkles in the medium. The wrinkle reducing section can change surfaces to come into contact with the medium. The medium transport apparatus having such a structure enables to reduce the formation of wrinkles in the medium.

The present disclosure a packaging apparatus for packaging bags equipped with a label printer, the packaging apparatus having a remarkably high packaging speed in comparison to packaging apparatuses of the related art. The packaging apparatus of the present disclosure includes a frame equipped with components for operating and controlling the apparatus therein, a bag feeding unit automatically conveying and feeding half-cut and wound bags, a label attaching unit installed on the frame and printing and attaching a label to the bags that are conveyed, and an opening and sealing unit opening tops of the bags, putting a product into the bags, and then packing the bags through sealing.

A sheet conveying apparatus includes a conveying roller, a pinch roller, a holding member, and a pressing device. The pinch roller includes a roller shaft and a roller body rotatable relative to the roller shaft. The roller shaft includes a first end portion and a second end portion. The holding member holds the roller shaft movably in a first direction. The pressing device presses the roller shaft in a pressing direction such that the roller body is pressed against a peripheral surface of the conveying roller. The first end portion of the roller shaft has a first contact surface being a planar surface. The second end portion of the roller shaft has a second contact surface being a planar surface. The roller shaft is disposed such that the first contact surface and the second contact surface are oriented in the pressing direction.

Provided is a sheet processing device capable of preventing a folded sheet bundle from being opened after pressing to improve accumulating property and aligning property of the sheet bundle. A sheet processing device includes: a pair of sheet pressing members 70 that press a fold of a folded sheet bundle in a thickness direction of the fold; and a moving member 56 that moves the sheet pressing member pair 70 along the fold of the folded sheet bundle. The moving member 56 supports a plurality of rows of the sheet pressing member pairs 70 arranged in a moving direction of the moving member 56. The sheet pressing member pairs 70 press the folded sheet bundle with the intervals therebetween in the respective rows reduced stepwise in the moving direction of the moving member 56.

At a printer that feeds a continuous paper unwound from a paper sheet supply unit in a sheet-shape to a printing head portion side via a damper portion, and then prints on a label of the continuous paper, in conjunction with an opening and closing operation of the printing head portion of the printing unit, the damper portion opens and closes in a vertical direction.

In one example in accordance with the present disclosure a device to detect media being wound around a wheel is described. The device includes a reel that collects the media and a movable arm pivotally coupled to the reel to provide tension to the media being wound around the reel. The device also includes a controller that detects media is being wound around the reel by 1) determining an angular position of the movable arm and 2) calculating, based on the angular position of the movable arm, when an output of a motor that rotates the reel is non-zero.

A printer includes a printing unit that performs printing on a printing medium; a winding unit that winds the printing medium on which the printing is performed by the printing unit; and a frame unit which is positioned between the printing unit and the winding unit on a feeding path of the printing medium, in which in a case where the printing medium is not wound by the winding unit, a receiving member for receiving the printing medium is detachably mounted to the frame unit, and in a case where the printing medium is wound by the winding unit, the receiving member is detached such that the frame unit comes in contact with the printing medium.
