The drive mechanism comprises a baseplate (1) with an oblong frame (2), from the forward end (3) of which there protrudes a wheel (4) driven by a motor (5) at the rear end (6). The frame, with motor and wheel, extends in the lengthwise direction w.r.t. to the baseplate. A spring (7) between a stop on the baseplate and the rear end of the frame thrusts the wheel against the driven component. |
