Claim:
1. A drive coupling mechanism for selectively driving a shaft of a rotatable member in an imaging device, comprising: a drive gear including an outer cylindrical portion, an inner cylindrical portion concentric with the outer cylindrical portion, and a plurality of tabs disposed along an inner surface of the outer cylindrical portion; a hub member including an annular portion having an outer surface and disposed around the inner cylindrical portion of the drive gear and a plurality of protrusions which extend from the outer surface of the annular portion in at least a radial direction; and a pin member being one of secured to an end portion of the shaft of the rotatable member and integral with the shaft, the pin member including a plurality of segments each extending in a different radial directions about the end portion of the shaft disposed about the end portion of the shaft, the end portion of the shaft disposed in the inner cylindrical portion of the drive gear and the annular portion of the hub member, wherein when the drive gear is rotated, the plurality of tabs of the drive gear directly contact the plurality of protrusions of the hub member to cause the hub member to rotate and the plurality of protrusions of the hub member directly contact the plurality of segments of the pin member to cause the shaft to rotate.
