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 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.

A printer includes a mainframe (10) including a front face part (11) that has an opening (13) through which a recording medium passes; a guide unit (30) connected to the mainframe (10) on a first side of the front face part (11); a printer mechanism unit (20) configured to perform printing on the recording medium, and connected to the mainframe (10) on a second side of the front face part (11) opposite to the first side thereof; an arm unit (50) having a first end connected to the mainframe (10); and a shaft unit (70) configured to hold a roll of the recording medium, and connected to a second end of the arm unit (50), wherein the guide unit (30) is configured to guide the recording medium so as to feed the recording medium to the printer mechanism unit through the opening (13) of the front face part of the mainframe (10).

There is provided an aligning device for a printing member in a printer in which it is presupposed to use a printer of a one-end supporting structure, the printing member (thermal transfer ribbon 3) can be used by selecting one of center alignment and one-end alignment, and the compatibility of printing data is taken into account. Focusing on provision of a rack and pinion structure within a cylindrical shaft 22, there are provide a pinion 16 rotatably provided within the cylindrical shaft 22 on a center line C across a width direction of the transfer path and a pair of racks 17 and 18, a push-in projection 19 configured to push the rack 17 toward the push-in end 22B of the cylindrical shaft 22, a positioning projection 20 configured to detachably engage with any of a plurality of positioning engagement holes 26 defined in the cylindrical shaft 22 along an axial direction. The push-in projection 19 drives the racks 17 and 18 and the pinion 16 by the pushing of the core tube 21 into the cylindrical shaft 22, and the positioning projection 20 engages with one of the positioning engagement holes 26 in the cylindrical shaft 22, and whereby the core tube 21 is positioned at the central position across the width direction.

A cardboard cylinder for winding a heat-sensitive transfer image-receiving sheet having a receptive layer on one surface of a support around the cardboard cylinder, wherein an innermost surface of the cardboard cylinder is composed of a layer containing a polyolefin resin having a number average molecular weight of 12,000 or more in a proportion of at least 80% by mass based on the layer.

L'invention concerne une installation d'impression d'une bande (24) souple en un matériau imprimable, destinée à être découpée en feuille après impression.

Cette installation est caractérisée en ce qu'elle comporte, entre le dispositif (17) d'approvisionnement en bande (24) et les moyens (2) d'avance de bande du module (1) d'impression, des moyens (4) moteurs, dits intermédiaires, d'entraînement en déplacement de la bande (24) dans le sens d'une avance de la bande en direction du module (1) d'impression et dans le sens d'un recul de la bande en direction du dispositif (17) d'approvisionnement

A tape printer (1) includes a holder support member (15) at one side end in a roll sheet holder storage part (4) in a direction substantially perpendicular to a feeding direction. A mounting piece (13), which is substantially rectangular in section and formed protruding outward on a positioning holding member (12) of a roll sheet holder (3), is fitted in the holder support member (15). The tape printer (1) further includes a flat portion (21) formed substantially horizontally between a rear edge of an insertion opening (18) through which a roll sheet (3A) is inserted into the tape printer. On the flat portion (21), a front portion of a guide member (20) is placed. At a rear edge of the flat portion (21) in the feeding direction, at plural positions corresponding to various kinds of the roll sheets (3A) having different widths, there are formed four second positioning grooves (22A-22D) in which part of the guide member (20) is fitted.

A cardboard cylinder for winding a heat-sensitive transfer image-receiving sheet having a receptive layer on one surface of a support around the cardboard cylinder, wherein an innermost surface of the cardboard cylinder is composed of a layer containing a polyolefin resin having a number average molecular weight of 12,000 or more in a proportion of at least 80% by mass based on the layer.

A tape printer (1) includes a roll sheet holder storage part (4) of which a bottom is formed with a positioning recess (4A) which is rectangular in plan view and long sideways and has a predetermined depth. A discrimination recess (4B) rectangular in plan view is provided between the positioning recess (4A) and an inner base end of a holder support member (15). The discrimination recess (4B) fittingly receives a sheet discrimination part (60) extending in a predetermined length from a lower end of the positioning holding member (12) inward at substantially right angle thereto. The sheet discrimination part (60) is formed with sensor holes (60A-60E) arranged in an L-shaped pattern. In the discrimination recess (4B), there are provided sheet discrimination sensors (S1-S5) arranged in an L-shaped pattern.

A top cover (5) and a guide member (24) form a discharge port (19). A plurality of guide ribs (28) is provided on an edge portion (5A) of the top cover (5). A plurality of projecting pieces (25) is provided on a guide member (24) at positions not to face to the guide ribs (28). These guide ribs (28) and projecting pieces (25) are used for guiding a roll sheet (3A) to a discharge port (19). At least one of the guide ribs (28) is provided with an extended portion (29) extending upstream in a feeding direction to prevent the roll sheet 3A from curving in a direction vertical to the feeding direction. Thus, the inability to discharge the roll sheet (3A) can be avoided.
