Abstract: A single actuator moves the chart and the marking implement in a chart recorder. A first drive means is used for advancing the chart to be recorded upon, a second drive means is used to move the marking implement, and an electromechanical actuator, responsive to an input signal, coupled to both the first and second drive means, exhibits a first direction of movement causing the marking implement to move and the chart to advance, and a second direction of movement causing only the marking implement to move. The electromechanical actuator preferably takes the form of a bidirectional stepper motor, though other types of motors and actuators such as solenoids may alternatively be utilized. Although useful with other types of chart recorders such as strip-chart recorders, the invention is particularly well suited to circular charts, since the shaft of the motor may be coupled to the chart movement mechanism by way of a rotatable disk.

Abstract: The present invention provides a novel structure of a tape cartridge accommodating a printing tape and an ink ribbon used for printing, which prevents the printing tape from being stuck in a cartridge case or the ink ribbon from being slackened. The tape cartridge of the invention has a mechanism for preventing an end of the tape from being reversely moved back into the cartridge case. A typical structure of the mechanism includes an anti-inversion system which prevents a tape core having a tape wound thereon from rotating in a reverse direction, that is, a direction opposite to a normal rotating direction for printing. The anti-inversion effects are removed when the tape cartridge is set in a printing device such as a tape writer to ensure smooth feeding of the tape for printing. When the tape is forcibly pressed back into the cartridge case, a movable platen clamps the tape between the platen and a fixed wall to prevent reverse movement of the tape.

Following the coupling step, in an adjusting step, the printhead-to-media spacing is selectively adjusted by the driving spacing adjuster with the motor for the total drive value. A method is provided of accommodating manufacturing tolerance variations accumulated during assembly of an inkjet printing mechanism having a printhead that prints on media in a printzone.
