摘要： In a printer, a drive motor, a drive roller arranged on the shaft of the motor, a reversal roller in spaced relation to the drive roller, and an elongated drive belt trained about the drive and reversal rollers form a tensioning device, the belt being fastened at its ends to a print-head carriage for selectively displacing the carriage in the forward and reverse directions along and relative to a printable substrate support roller or base. The reversal roller is carried in a carrier housing which movably and cooperatively engages a spring-loaded tensioning wedge for maintaining the elongated drive belt in a predetermined tensioned or stretched relation. In order to avoid the need for a separate or specialized drive motor and an additional drive belt for advancing an inked printing ribbon, the drive force for the inked-ribbon drive shaft is derived from the reversal roller which, in the normal operation of the printer, is rotatable in opposite directions for selectively positioning the print-head carriage along the printable substrate support. For this purpose, a clutch member is interposed between the reversal roller and a gearwheel associated with the inked-ribbon drive shaft, the clutch member being longitudinally movable into coupled and uncoupled relations with the inked-ribbon gearwheel as a function of the direction of rotation of the reversal roller.

摘要： A ribbon is driven past the printing station of a printer only when the print head is moved in the right-to-left direction across the printer. An endless timing belt causes rotation of a gear pulley that is in mesh with an idler gear. The idler gear is supported on a pair of projecting fingers of a plate that is swingable on the center of the gear pulley. The idler gear is responsive to the direction of rotation of the gear pulley through a drag effect of the projecting fingers with the bottom surface of the idler gear.

摘要： An inkribbon feed mechanism is disclosed which feeds the inkribbon by utilizing power of a spacing motor by which a print head is transversed. The inkribbon feed mechanism comprises commanding means which detect a command element for reversing the inkribbon near one end of the inkribbon, an arm member which interlocks with the command means via a spring member and is pivotably supported by a pivot, a planetary gear member which is provided at one end of the arm member and is rotated by the power of the spacing motor via a drive gear member. In compliance with the alternate rotation of the spacing motor, the planetary gear member engages with a gear member of one reel or is slightly moved in orbit by the drive gear member so as not to render a rotational force to the reel. The arm member is pivoted by the command means to change the object which the planetary gear engages.

摘要： A printer arrangement of the type which prints data serially along a line on a record medium by relative impact of type characters and record medium through a ribbon. Printing is a mixture of stop and go printing, essentially a character at a time, and continuous printing of a plurality of characters. Driving power for the ribbon is derived from carriage movement on which the print head is mounted through controllable clutch and toggle switch action. The toggle switch action reverses ribbon drive direction in response to a depletion of ribbon signal.
