PROBLEM TO BE SOLVED: To obtain the driving device of a rotary body constituted so that an installing space thereof can be reduced and such possibility that one rotary body out of the plural rotary bodies is affected by the rotation irregularity and the mechanical vibration of the other rotary body is avoided. SOLUTION: This driving device is provided with the plural rotary bodies 31 and 37, a rotation driving source 331 transmitting rotational force to one rotary body 31 through a driving transmitting means 72 and a driving branching means 74 branching the rotational force of the source 331 as the driving for driving the other rotary body. The branching means 74 is constituted so as to be provided with a main driving rotation part 71 and a follower rotation part 751 rotated in accordance with the rotation of the rotation part 71 based on a magnetic action between the rotation part 71. Thus, since the rotation irregularity or the like of the rotary body can be absorbed in comparison with a case that the rotational force is blanched by mechanical coupling, an adverse effect is surely prevented from being exerted on the other rotary body. |
