    摘要: The feeding of typewriter ribbons is improved by utilizing a cartridge carried driving element engaging the periphery of a translatable take-up spool where the driving element is driven by an interface connection with a driving member connected either directly or through a gear reduction train to a stepper motor. The simplified ribbon feed mechanism provides control over the increment of feed electronically as well as each ribbon cartridge carrying the appropriate gear reductions, if necessary, for different types of ribbons.

    摘要: A regulator adapted to regulate the throughput of an ink between an ink source and a print head includes: (a) a pressurized chamber including an ink inlet in fluid communication with and ink source, an ink outlet in fluid communication with a print head, and at least one flexible wall; and (b) a lever including a flexible arm extending along a portion of the flexible wall and an opposing arm operatively coupled to a seal biased to close the ink inlet when the lever is in a first position and to open the ink inlet to allow fluid communication between the ink inlet and the pressurized chamber when the lever is pivoted to a second position; where a lower pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm, pivoting the lever to the first position (inlet closed), where a higher pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm to pivot the lever to the second position (inlet open), and where a pressure change from the lower pressure differential to the higher pressure differential across the flexible wall causes the flexible wall to actuate and flex the flexible arm without causing the lever to pivot.

    摘要: A fabric ribbon (13) is stuffed in a cartridge chamber (11). Two pinch rollers (35 and 39) are driven by a third roller (29). The direction for forces from the pinch rollers is toward a wall portion (9a), which is near an opening having a dam (ridge 67) which leads to chamber (74) have an exit slot (71) located near the wall portion (9a). The drive roller (29) is positioned to be located where the drive roller of an existing cartridge was located, making this cartridge interchangeable with a cartridge for a spool-to-spool ribbon.
