Abstract
An inked ribbon spool 1 for a printer comprises a drum 2 having a bore 4 for reception of an idler spindle. Flanges 6 are provided on each side of the drum 2 and an annular internal involute bear 10 driven by a pinion 17. The gear drive mechanism allows a positive rotation of the spool 1 to be accurately controlled with low torque for controlled acceleration and deceleration. A ribbon is secured to the spool by engaging a fixing barb 15 in a transverse slot 11 in the drum and/or by engaging a ball shot in a square hole 24 in the drum 2.
