摘要： An object is to provide a thermal transfer printer having an inexpensive configuration and capable of making a tension given to an ink ribbon as constant as possible, even when a secular change and an environmental change occur in a DC motor used as a supply motor and a winding motor. A supply motor control unit controls a supply motor of an ink ribbon supply unit. A winding motor control unit controls a winding motor of an ink ribbon winding unit. A remaining amount detection unit detects a remaining amount of an ink ribbon. A variable calculation unit acquires parameters for an armature current, an applied voltage, and a rotational speed of each of the supply motor and the winding motor, and calculates variables to be used for controlling the supply motor and the winding motor on the basis of the acquired parameters.

摘要： A printer with a single motor system to match torques between ribbon supply and ribbon take-up is provided. The printer comprises a ribbon supply spindle, a take-up ribbon spindle, sensors to output ribbon width and diameter at ribbon supply, and a sensor which outputs ribbon diameter at ribbon take-up. The printer is provided with a drive system providing rotation to the ribbon supply via tension on the ribbon loaded on the ribbon supply spindle and taken-up on the take-up ribbon spindle. Firmware, communicatively linked to the sensors and the drive system, is configured to calculate ribbon tension at the ribbon supply spindle, to calculate the torque required on the ribbon on the ribbon take-up spindle to match the ribbon tension at the take-up spindle to the ribbon tension at the ribbon supply spindle, and to adjust the drive system to match these torques.

摘要： To provide a printing apparatus capable of preventing the image quality from deteriorating, the printing apparatus is provided with a ribbon 41 laid between spools 43, 44, DC motors Mr3, Mr1 for rotating these spools, driver for supplying driving power to the motors, encoders for detecting rotation amounts of the motors, and controller that controls the driver. A CPU drives the motor without the tension due to the ribbon 41 being applied, calculates the rotation velocity of the motor based on the rotation amount of the motor detected in the encoder, applies the calculated rotation velocity and the supply current in driving the motor to the relationship between the rotation velocity and the supply current in a reference motor, and calculates the supply current for providing the same rotation velocity as the rotation velocity in driving the reference motor with the supply current of the time the motor is driven.

摘要： A thermal printer having a supply of media with a rotatable platen on which the media is moved for printing by a thermal printing head. A supply spindle supplies print ribbon from a supply spool mounted thereon, and a take-up spindle takes up the used print ribbon on a take-up spool. The spindles are each driven by a motor and controlled by a controller which detects the Back EMF (BEMF) of the motors, and calculates the velocity of the spindles, spool, and print ribbon to control each motor based on the BEMF. The status of the print ribbon as to low condition, breaks, ribbon full and other monitoring functions can be provided to a remote host computer or other monitoring station.

摘要： This invention relates to a cartridge 11 for a printing ribbon 13 comprising a container 12 which houses an inked ribbon 12, a ribbon feeding roller 18 and a ribbon inking element 14. The inking element 14 is selectively actuated from a rest condition in which, during the cartridge utilization initial phase, the inking element does not supply the ribbon 13 with ink, to a work condition in which the inking element 14 supplies the ribbon with ink. A reducing unit 34 and a cam 33,42 are provided for automatically actuating the inking element 14 and guide it from the rest to the work condition, when a predetermined number of turns is reached by the feeding roller 18 for advancing the ribbon.
