Abstract: Disclosed is an adjustable paper blocking structure of a thermal printer, comprising: a base evenly provided with a plurality of tooth grooves; a paper blocking component slidably connected to the base and used to limit the two ends of label paper in the middle of the paper tray of the desktop thermal printer, and a locking component having one end rotatably connected to the paper blocking component and the other end engaging with the tooth groove. The proposed adjustable paper blocking structure of a thermal printer can be used for label papers of different sizes and improves printing accuracy.

Abstract: A media hanger/guide comprising a media hub having a top surface and a channel extending through a portion of the top surface. The media hanger/guide further comprises two mounting brackets positioned in the channel, each mounting bracket having an elongated member and each elongated member having a plurality of teeth located thereon. Each mounting bracket also has a support member connected thereto. At least a portion of each support member is located outside of the channel of the media hub. The support members are adapted for lateral movement along the channel of the media hub relative to the top surface of the media hub. The media hanger/guide further comprises two gears positioned in the channel. Each gear is in operable connection with the teeth of one of the mounting bracket's elongated members. The gears are also in operable connection with each other.

Abstract: A media spindle apparatus for supporting a media roll having media to be delivered to a printing apparatus. The apparatus includes a spindle configured to support the roll. The spindle defines an axial direction about which the roll rotates relative to the printing apparatus to deliver the media to the printing apparatus. A guide member is supported by the spindle and guides the media to the printing apparatus. The guide member is positionable in a first configuration in which a securing mechanism is disengaged and the guide member is translatable substantially in the axial direction relative to the spindle. The guide member is pivotable about the axial direction relative to the spindle to move to a second configuration and thereby engage the securing mechanism to inhibit the guide member from translating in the axial direction relative to the spindle and pivoting from the second configuration to the first configuration.

Abstract: A paper roll fixing device of a printer is provided. The paper roll fixing device includes a first supporting member and a second supporting member. The first supporting member includes a first supporting protrusion part and plural first auxiliary rollers. The second supporting member includes a second supporting protrusion part and plural second auxiliary rollers. The first supporting protrusion part and the second supporting protrusion part are inserted into two ends of a hollow shaft of a paper roll. Consequently, the paper roll is fixed in the space between the first supporting member and the second supporting member, and supported by the first auxiliary rollers and the second auxiliary rollers. Moreover, especially, the paper roll fixing device is applicable to a variety of paper rolls with different diameters.

Abstract: Medical devices and methods are provided for rolling an endoscopic sheet into a tubular configuration.

Abstract: A paper roll mounting device, configured to enable a paper roll to be supported by a paper roll supporting means provided to each arm of pairs of arms by rotary-driving a female screw member to individually move each arm in a direction parallel to a rotating shaft, is provided with: a female screw rotation amount signal output means provided to output a rotation amount signal corresponding to a rotation amount of the respective female screw member, individually on a female screw member basis, in response to rotation of the female screw member; and an arm stop position control unit configured to enable setting of a reference position for each of the arms, and, when changing a position of each of the arms in an axis direction of the rotating shaft, to enable input designation of a stop position of each of the arms, and to detect a current position of the arms with respect to the reference position by calculating a movement amount of the arms based on the rotation amount signal, and thereby move each of the arms

Abstract: A novel system for mounting welding wire spools of different sizes on a mounting spindle of a wire feed system is provided. The invention may reduce or eliminate wire feedability difficulties and welding arc outages arising from misalignment of the wire spool and inconsistent wire feeds. The invention provides a medium and large wire spool mounting system including a spool mounting hub, a movable back plate configured with a locking slot arrangement, and a left threaded nut plate. Furthermore, the invention provides a system for mounting small wire spools on a keyed shaft of a wire feed system comprised of washers, a spring, and a knurled nut. A braking system including washers, a spring, and a knurled nut is provided for the prevention of wire spool free wheeling during non-welding periods.

Abstract: Disclosed are a printer and a stacker and methods. The printer prints selectively on one or both sides of a printable web and sheets or labels are cut from the web and stacked in the stacker. The printer has an unwind or unwind mechanism that accepts and holds web rolls of different widths in center-justified relationship with respect to a print head. The printer has a spindle for mounting an ink ribbon core with a detent for center-justifying the ink-ribbon with respect to the print head.

Abstract: A centering photographic material winding device for the winding or unwinding of a photographic material web onto or from a winding core. The winding device includes a winding core seat which is adapted for receiving a winding core moveable on the winding core seat. The winding core is centered by two push members which are coupled in their movement for the displacement and centering of a winding core received on the winding core seat between the push members in that the push members evenly move towards one another.

Abstract: A method and apparatus for mounting a supply roll to a rotatable support shaft in an imaging system. The apparatus includes a first collet/collar assembly for accurately positioning the supply roll at a desired location on the support shaft, and a second collet/collar assembly for frictionally coupling the support shaft to an interior surface of a supply core of the supply roll using a deformable gland.
