A supporting and driving mechanism including a rotatable body and a supporting unit for assuring stable support and rotation of the rotatable body for a long time. The mechanism includes an axis member at either end of the rotatable body, a driven gear at one end of the rotatable body, two rollers and a driving gear of the supporting unit. The two rollers are placed parallel to each other and the distance between the closed surfaces of the rollers is smaller than the diameter of the axis member of the rotatable body. The driving gear engages the driven gear and transmits a driving force to the driven gear of the rotatable body. The driving force applied from the driving gear to the driven gear directs between the centers of the two rollers when the driving force is translated so that the origin of the force is brought to the center of the axis member of the rotatable body. Thus the axis member is pressed toward the two rollers while the rotatable body is driven by the supporting unit, whereby the position of the axis member is fixed and the stable rotation of the rotatable body is assured for a long time.
