A media cartridge is disclosed for insertion into a cartridge receptacle of a printer. The media cartridge includes a cartridge housing having one or more shifting ribs on the cartridge housing. At a position of initial insertion of the media cartridge into the cartridge receptacle, the shifting ribs are configured to center a length of media and an ink ribbon of the media cartridge between a print head and a platen roller in the cartridge receptacle. As the insertion of the media cartridge into the cartridge receptacle continues, the shifting ribs shift the length of media and the ink ribbon toward one of the print head and the platen roller.

A cartridge assembly is disclosed. The cartridge assembly includes a cartridge housing defining an internal chamber. At least one rotatable spool is housed in the internal chamber. In the wall of the cartridge housing, a ribbon lock is formed. The ribbon lock has an engaged position and a disengaged position. In the engaged position, the ribbon lock is biased into engagement with the rotatable spool(s) to inhibit rotation of the rotatable spool(s). In the disengaged position, the ribbon lock is urged away from the rotatable spool(s) to disengage the ribbon lock from the rotatable spool(s) to permit rotation of the spool(s).

Ribbon tension detecting means (20, 21), which are formed of a plate-like lever body (35) each, are located individually on the upstream side and the downstream side of a platen (7) with respect to its travel. The plate-like lever body (35) has first and second rollers (47, 48) on the upstream and downstream sides with respect to travel of a ribbon, and swings around an axis of rotation of the second roller (48), depending on a tension of the ribbon traveling guided by the rollers (47, 48). If the amount of its swing is not less than or not more than a fixed value, a ribbon feed motor (18) or a ribbon take-up motor (19) is driven. Further, the ribbon tension detecting means (20, 21) are provided with a smoothing member which touches the ink ribbon (13) to remove wrinkles from the ink ribbon (13).

Systems and methods for duplex printing of print sheets are described. In one aspect, a duplex module is configured so that print sheets may be controllably and reliably re-introduced into a print module in an orientation that is suitable for marking the second side of the print sheet without requiring a support structure that spans the entire width of the print sheet. In large format printing applications, this feature avoids large and heavy support structures, such as feed rollers, that otherwise would be needed to support the print sheets, as well as their own weight. In this way, a printing apparatus may provide duplex printing functionality with a structure that has a relatively light weight and a relatively small overall footprint.

A color thermosensitive recording sheet extends two-dimensionally in main and sub scan directions perpendicular to each other. In a thermal printer for use with the recording sheet, two cutters remove front and rear margins from the recording sheet by cutting the recording sheet along lines extending in the main scan direction. Two slitters remove first and second side margins from the recording sheet by slitting the recording sheet along lines extending in the sub scan direction. A slitter shifter shifts the slitters in the main scan direction between a slitting position and home position. The slitters are set at the side margins when in the slitting position, and away from the recording sheet when in the home position. An externally operable mode selector selectively sets a marginless mode and margin mode. A controller causes the slitter shifter to shift the slitters to the slitting position when the marginless mode is set, and actuates the cutters and slitters. The controller causes the slitter shifter to shift the slitters to the home position when the margin mode is set, and disables the cutters and slitters.

The present invention provides a card recording apparatus capable of printing in high speed as well as reducing overall dimensions of the apparatus. After a card is transported to an information recording section 200 in a lateral (short length) direction of the card, an information signal is recorded on the card thereby. Then, the card is transported to a second heating section 300. An ink image formed on an intermediate recording medium 7 by a first heating section 500 is re-transferred to the card by the second heating section 300. A warp developed on the card by the second heating section 300 is corrected by a card warp correcting section 400.

A data reading apparatus for reading and/or scanning data from a first and second scanned medium comprising a first transportation path P1, along which the first scanned medium is conveyed and a second transportation path P2, along which the second scanned medium is conveyed and wherein the first and second transportation paths each have a common mutually shared middle transportation path through which both scanned media must pass and a common data reader reading data from each scanned medium respectively. Checks S are conveyed on the first transportation path P1, cards C are conveyed on the second transportation path P2 at a different transportation height from that of the first transportation path P1 with data read from the respective media as they are being conveyed. Because the transportation heights differ, scanned media can be transported on different transportation paths without involving special switching devices.

Contactless power and communications links are established between a printer engine and a peripheral device installed on a replaceable printer component. For peripheral devices incorporated within or on the replaceable component, power is inductively transferred from a primary winding on the printer engine to an adjacent secondary winding on the replaceable component without the use of direct physical contact between electrical conductors. In addition, communications between the printer engine and at least one peripheral device on board the replaceable component are provided without making direct physical contact between electrical conductors. The communication task is accomplished in one of several ways. For a first embodiment of the invention, control signals are sent from the printer engine to the replaceable component over the inductive power coupling circuit by switching between two frequencies of alternating current applied to the primary winding on the printing engine. The frequency switching is decoded on board the replaceable component to provide control signals for the peripheral device. For communications in the opposite direction, the peripheral device may send information to the printer engine by modulating a resistive load coupled to the secondary winding. Current flow through the primary winding will vary in response to the load on the secondary winding. The variations in current flow on the printer engine side are decoded to signals which the printer engine comprehends. For a second embodiment of the invention, signals are inductively transmitted across a narrow gap. For a third embodiment of the invention, communications are handled by transmitting and receiving modulated infrared energy across a narrow gap.
