  • Driving device for a printing carriage provided with a print head
    Patent number: 4294554
    Abstract: A driving device for a printing carriage (20) with print head (22) including printing elements (24) which print characters on a data carrier includes a motion converting means (14) with a closed gear path (16) converting the rotational movement of a motor driven pinion (10) to a reciprocating movement of the printing carriage along the data carrier. Two pivotable gear segments (26, 28) which are in engagement with each other and with the motion converting means move the printing carriage in any of two directions parallel with the data carrier when the pinion is in engagement with any one of two straight gear paths (16a) on the motion converting means and permit the displacement of the motion converting means perpendicularly to said directions when the pinion is in engagement with any one of two curved gear paths (16b) which connect said straight paths (16a) on the motion converting means.
