Abstract
A rotational driving apparatus with frictional engagement includes a base, a rotating member having rigidity and axially supported on the base, at least one frictional roller having rigidity and at least one driving roller which are in rolling contact with the rotating member, a motor for rotating the driving roller, and a pressing mechanism for pressing the frictional and driving rollers against the rotating member, thereby transmitting a driving force of the driving roller to the rotating member to rotate it.
