A tape dispenser housing wound adhesive tape includes a brake spoke tapering (i.e., narrowing) from a distal radial end to a proximal radial end relative to a tape rotational axis, wherein the brake spoke effectuates the braking of wound adhesive tape on a hub by contacting the wound adhesive tape, the hub, or both simultaneously.

A roll paper holder is provided which rotatably holds belt-like paper to be conveyed towards a printing section when a roll of paper is obtained by winding the paper on an upstream side in a conveyance direction with respect to the printing section. The roll paper holder includes a side wall section in contact with both side ends of the roll of paper in a width direction to prevent the roll of paper from moving in the width direction. The holder further includes at least one protrusion located outside a range where it can contact with the side end of the roll paper to be held having the largest diameter in the side wall section. The at least one protrusion is configured to protrude by a predetermined dimension from a portion contacting with the side end to control a position of the paper in the width direction.

Automatic sheet feeding of an installed roll is performed more reliably. To this end, a leading end of a sheet is detected on the basis of a change in an output value of a sensor while causing a roll to rotate in a winding direction using a sensor capable of detecting a distance to the sheet separated from the roll. After the detection, the roll is caused to rotate in a feeding direction, and a feeding state of the sheet is determined on the basis of a change in the output value of the sensor.

A media roll holder assembly for a roll is detachably supported in a printing system. A rotational drive includes a roll engaging element configured for fittingly engaging and driving a drive engaging element of a roller, for example an Oldham coupling. A first guide surface is configured to support and direct the roller in a loading direction. A second guide surface at least partially extends at an angle with respect to the first guide surface, such that movement of the roller over the first guide surface brings the drive engaging element in contact with the second guide surface. The second guide surface directs the drive engaging element into a predetermined orientation, which orientation aligns the drive engaging element with the roll engaging element in a loading orientation, such that further movement of the roller in the loading direction inserts the drive engaging element into the roll engaging element.

A stretch film dispenser with a moving device includes a frame. The frame includes a bottom seat and a coupling seat. A tubular member is connected between the bottom seat and the coupling seat. The tubular member is provided with a telescopic rod. The bottom seat is provided with a moving unit. A bottom surface of the moving unit is provided with at least two first moving members. When in use, the telescopic rod is pulled to a height suitable for holding, and then the user holds the telescopic rod to pull the stretch film dispenser. The stretch film dispenser can be moved through the moving unit, thereby achieving the effect of moving the stretch film dispenser easily and conveniently.

A stretch film dispenser with a lifting device is disclosed. The lifting device includes a first operating unit. The first operating unit has a first through hole. The first through hole is provided with a first fixing member. The first operating unit further has a first opening. The first opening is provided with a first control member. The first operating unit is connected with an accommodating unit. The accommodating unit includes a telescopic rod therein. An outer peripheral wall of the telescopic rod is formed with a plurality of spaced first positioning holes corresponding to the first fixing member. The first fixing member is engaged in one of the plurality of first positioning holes for positioning the telescopic rod. Thereby, the telescopic adjustment of the telescopic rod is controlled by the first operating unit for articles of different heights, and the packing process is more smooth and convenient.

A cutting device includes a fixed blade and a movable blade that slides with respect to the fixed blade during cutting, the movable blade having a first end that engages with the fixed blade at cutting start and a second end that engages with the fixed blade at cutting end, an urging member connected to the movable blade to urge the movable blade towards the fixed blade and a rotation of the movable blade in a first rotational direction, and a support for the movable blade having a shaft that rotates as the movable blade moves, the shaft having a center portion and first and second ends rotatably connected to the movable blade, wherein points of connection of the first and second ends are at locations that urge a rotation of the movable blade in a second rotational direction opposite the first rotational direction.
