Abstract: An apparatus wherein a hot stamp transfer roller can be quickly removed from the metal core after the hot stamp transfer roller is used up and immediately replaced with another hot stamp transfer roller so that the process can continue without having to return the central hub and the remaining portion of the hot stamp transfer roller to a facility where the hot stamp transfer roller is ground away from the central hub.

Abstract: A roll sheet supporting apparatus includes a pair of rotation shafts which are respectively fitted into end portions of the hollow portion of the core tube and configured to support the roll sheet rotatably and capable of being drawn out, an engaging member movable between a projecting position and a retracting position, wherein the engaging member projects from an outer circumferential surface of the each rotation shaft abutting on the core tube to engage with the core tube at the projecting position and retracts inward from the outer circumferential surface of the each rotation shaft at the retracting position, and an engaging member moving unit configured to move the engaging member between the projecting position and the retracting position.

Abstract: A core tube holding device comprising: a plurality of out-pushing members that are arranged side by side spaced apart in the axial direction, each having a pressing part; a connecting member for connecting the plurality of out-pushing members; a holding member that has at every position in the axial direction a pressed part corresponding to the pressing part, and that is disposed radially outward with respect to the plurality of out-pushing members; and an action unit adapted to exert a force for moving, to one side in the axial direction, a one end out-pushing member which, among the plurality of out-pushing members, is at an end on the one side; wherein: at least one from among the pressing parts and the pressed parts is formed in a tapered shape that spreads radially outward from the one side to the other side in the axial direction, and when the force for moving the one end out-pushing member acts thereon via the action unit, the one end out-pushing member moves to the one side while also pulling the othe

Abstract: A sheet storage cassette which contains a print sheet in roll form and is attached to a printing apparatus, comprises: a shaft which retaining the print sheet in roll form; and a support portion rotatably supporting the shaft, wherein an urging member protrudes from a maximum outer diameter of the shaft while the print sheet is not attached to the shaft, and urges the inner surface of a hollow portion of the print sheet while the print sheet is attached to the shaft, and a rib portion which continuously extends in a rotational direction and contacts a pickup guide, when the urging member rotates, the rib portion is provided to prevent the pickup guide from interfering with the urging member which rotates together with the shaft.

Abstract: A reel-to-reel assembly is provided. The reel-to-reel assembly includes, but is not limited to a supply spindle and a wind-up spindle. The supply spindle receives a supply reel having a length of ribbon wrapped around the supply reel. The wind-up spindle receives an initially empty wind-up reel. The wind-up spindle includes an adjustment mechanism for varying the outer diameter DO of the wind-up spindle from an initial outer diameter DOi to a final outer diameter DOf which is larger than the initial outer diameter DOi.

Abstract: A bobbin holder for tensioning a bobbin tube and receiving a wound thread bobbin is presented. The bobbin holder includes a rotatable drive shaft that is connected to a drive with a bearing end thereof and that has a tensioning device for tensioning a bobbin tube on a tensioning end. The tensioning device includes a plurality of bobbin tubes on the periphery of the drive shaft and interposed tensioning rings. A tensioning piston guided on the free end of the drive shaft acts upon at least one of the bobbin tubes to deform the tensioning rings. In order to allow the use of high fatigue strength materials for the tensioning ring, the tensioning ring includes a continuous separating slot on the periphery, which extends between two opposite ring ends of the tensioning ring, deformation being essentially achieved by an expansion of the tensioning ring.

Abstract: This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing.

Abstract: A carbon ribbon shaft is provided for a barcode printer and includes a shaft rod and at least one first rotation member and one second rotation member. The shaft rod has an end coupled to a housing of the barcode printer. The first and second rotation members are fit over the shaft rod. Arranged between inside of the first rotation member and the shaft rod is a resilient element that allows the first rotation member to effect resilient rotation with respect to the shaft rod. The first rotation member has an outer surface forming sliding-resistant resilient tabs. Arranged between inside of the second rotation member and the shaft rod is a resilient element that allows the second rotation member to effect resilient rotation with respect to the shaft rod. The second rotation member has an outer surface forming sliding-resistant resilient tabs. The surfaces of first and second rotation members receive a carbon ribbon roll of the barcode printer to fit thereon.

Abstract: A tightening mechanism for adjustably setting a tape holder to an immovable state on a tape dispenser includes a tape holder being provided at an axially outer end with a flared round recess, a bushing ring having a bevel wall and being fitted in the flared round recess, and a locating member slightly smaller than the bushing ring for fitly seating in the bushing ring. A turning knob having a spring put thereon is sequentially extended through the locating member and the bushing ring to screw into a fixing bar, on which the tape holder is mounted. When the knob is turned, a tightness of the bushing ring against the flared round recess is progressively changed to thereby adjust the tape holder to different degrees of immobility, allowing the tape dispenser to apply to tapes of different adhesion ability.

Abstract: A spool, such as supply for a wide-format printer, is provided. The spool comprises a spindle for slidingly receiving an outer shaft, which is typically the core of a roll of print media. A first resiliently deformable gripping ring is circumferentially mounted about the spindle, and a compression mechanism is provided for axially compressing the gripping ring. The axial compression causes radial expansion of the gripping ring, thereby urging the gripping ring into gripping engagement with the outer shaft received on the spindle.

Abstract: An easily tear-off tissue holder includes a base, a shaft connected with and standing on the base, a fix rod connected with the shaft and having a slide hole for an upper small diameter connect rod of the shaft to fit and move up and down therein, and a press member connected on top of the fix rod to press down the fix rod and an elastic cylindrical member. When the press member is pressed down the fix rod and the elastic cylinder member, the elastic cylinder member with vertical slots and of narrow strips defined by every two neighboring vertical slots may elastically bend diametrically outward to push an inner wall of a cylindrical shaft of a coil tissue to stop the coil tissue immovable for easily tearing off a proper length of the tissue, by which the coil tissue may not be smeared in tearing off action.
