摘要： A printer ribbon 6 is mounted on two spools 7,11 each of which is driven by a respective stepper motor 14,15. A controller 17 controls the energisation of the motor(s) such that the ribbon is transported in at least one direction between the spools mounted on spool support(s) 8,12. The controller is operative to energise both motors to drive the spools of ribbon in the direction of ribbon transport to achieve push-pull operations. Ribbon tension is monitored to enable accurate control of ribbon supply and ribbon take up. The tension is monitored by checking power supply to the stepper motors. The arrangement may be used for both continuous and intermittent printing applications.

摘要： A label printer comprises a supporting frame having a pair of side plates (14, 15) facing each other. A print head (39) and a platen roller (24) are arranged between the side plates. Above the print head is arranged a ribbon supply device (45) for running a transfer ribbon between the print head and the platen roller. The ribbon supply device includes a ribbon unit (46) supported on a supporting mechanism (44), and a ribbon drive section (47) attached to the side plate so as to drive the ribbon unit. The supporting mechanism includes a fixed arm (43) fixed to one of the side plates, and a slider (91) mounted on the fixed arm. The slider supports the ribbon unit thereon and slidable between a first position wherein the ribbon unit engages the ribbon drive section and a second position wherein the ribbon unit is situated outside the supporting frame.

摘要： An apparatus (10) for printing graphic images on sheet material (S) has a thermal print head (30) with a linear array of heating elements pressed into engagement with an ink web (W) overlying the sheet material on a platen (32). The platen (32) extends in the lengthwise direction of the print head (30) across the width of the sheet material (S), and is rotatably driven to in turn drive the sheet material with the ink web (W) relative to the print head. A removable cassette (34) having a predetermined length (L) of ink web (W) bearing a printing ink is mounted adjacent to the print head (30) with the ink web interposed between the sheet material and the print head for printing the graphic images on the sheet. A supply spool (36) carrying the ink web (W) is rotatably mounted in the cassette (34), and a take-up spool (38) is also rotatably mounted in the cassette for receiving the ink web (W) from the supply spool upon passage between the platen and print head. The take-up spool (38) defines a first overall diameter (D1) without receiving the ink web (W) from the supply spool (36), and a greater second overall diameter (D2) upon receiving the predetermined length (L) of ink web, wherein the second overall diameter (D2) is no more than 10% greater than the first overall diameter (D1). A spring-wrapped clutch (42) is drivingly connected between a take-up motor (40) and the take-up spool (38) to impart a constant torque ( tau C) to the take-up spool (38) for winding the ink web (W) onto the spool during printing operations and to thereby maintain a substantially constant tension (Tw) within the ink web.

摘要： A thermal transfer recording apparatus for recording an image on a recording medium (11) by transferring ink on an ink sheet (14) onto the recording medium (11) is provided with a loading unit for the ink sheet (14), a means (17, 18) for conveying the ink sheet, a means (12, 16) for conveying the recording medium, a detection means for detecting the loading of the ink sheet and a recording means (13). When the detection means detects that the ink sheet is loaded into the loading unit, the ink sheet (14) is conveyed by a predetermined amount by the ink sheet conveying means so as to take up the slack on the ink sheet.
