摘要： A ribbon cartridge for a thermal transfer printer is configured to provide a retractable feed for a donor ribbon. The ribbon cartridge includes a housing, a roll of donor ribbon wound on a core within the housing, and a clutch operatively coupled to the core. A resilient structure is coupled to the clutch and to the cartridge housing such that the release of energy stored in the resilient structure by advance of the donor ribbon produces retraction of ribbon slack, if the donor ribbon is released or backfed. Alternatively, a ribbon roll having a self-contained clutching and slack take-up capability includes a hollow core configured to receive a roll of ribbon and a clutch having a friction component configured to induce frictional engagement with the core. At least one end of the clutch is adapted to be externally constrained, and a resilient component is located between the friction component and at least one end of the clutch.

摘要： A clean print ribbon feed system and method for a printer having a ribbon with two non-inked clean hands portions wound around a pair of spools is disclosed. Detection of the spool having greater angular velocity and lesser angular velocity determines the direction of feed. The spool having greater angular velocity winds and takes up the print ribbon. The non-inked portion can be formed as a conductive plastic and is initially wound on each spool. Detection of the non-inked portion of the ribbon takes place by two electrical contactors. The determination of the angular velocity of the spools determines the amount of print ribbon on one of the spools so that the spool having the lesser ribbon can be driven as a take-up spool to provide proper directional drive for winding the clean hands portion and the inked portion which follows.

摘要： A ticket-printing device has a ribbon sensor and a mode-switching circuit. The mode-switching circuit automatically selects different printing conditions depending on whether or not the ribbon sensor detects the presence of an ink ribbon. The ink ribbon is wound on a supply spool and take-up spool. When the ink ribbon is replaced, a ribbon fixture holds the supply spool and take-up spool in correct relative positions so that they can be easily slipped onto a supply spool shaft and take-up spool shaft in the ticket-printing device.

摘要： A printer is capable of preventing the formation of creases in a portion of an ink ribbon corresponding to a print head and of printing characters and images in good print quality without forming streaks attributable to creases in the ink ribbon. A main frame supports a feed spool and a takeup spool so that an ink ribbon extends between the feed spool and the takeup spool. A print head support frame supporting a print head and an ink ribbon guide is supported pivotally at one end thereof on the main frame. When the print head support frame is locked in place on the main frame, the ink ribbon guide depresses the ink ribbon so that the tension of a portion of the ink ribbon on one side of the main frame is higher than that of a portion of the same on the other side of the main frame while the printer is in an unoperational state and tension is distributed uniformly across a portion of the ink ribbon corresponding to the print head while the printer is in an operational state. Thus, creases are not formed in the ink ribbon while the printer is in the operational state.

摘要： An apparatus for use in a thermal printer for printing bar code symbols onto a paper substrate material is provided which utilizes a ribbon having a multi-transfer ink layer. The thermal printer enables the ink ribbon to be transported at a rate that is selectively lower than the transporting rate of the paper substrate. The thermal printer comprises a platen and a thermal head disposed adjacent to the platen having a region defined therebetween through which the paper substrate material is transported at a first rate. Images or symbols are imprinted onto the paper substrate material by operation of the thermal head in cooperation with ink from the multi-transfer ink ribbon advanced to the region. A supply hub carries a supply of the ribbon, and a first motor is mechanically linked to the supply hub. The first motor rotates the hub in a direction opposite to a direction of advancement of the ribbon. A roller is mechanically linked to the first motor and has a surface engaging the ribbon provided with a friction coefficient sufficient to prevent slippage of the ribbon across the surface. A second motor applies a tension on the ribbon, and a clutch interposed between the first motor and the supply hub permits controlled slippage of the supply hub to permit advancement of the ribbon. A take-up hub mechanically linked to the second motor receives the ribbon after its passage through the region between the platen and the thermal head.

摘要： A method and apparatus for controlling tension on a sheet material in a reel-to-reel transport system. The sheet material is feed along a defined path from a supply reel to a take-up reel. A motor is operatively connected to the take-up reel for applying a torque to the take-up reel while a sensor is positioned to detect rotation of the supply reel. A microcontroller enables the motor with an initial PWM pwm.sub.o to create torque on the take-up reel and then incrementally increases the PWM. When the sensor indicates that the supply reel has moved, the current PWM is stored in memory as pwm.sub.i. This pwm.sub.i is subsequently used by the apparatus to determine a desired tension on the thermal ribbon.
