ABSTRACT:
A rotary drive mechanism selectively and rotationally drives at least first and second bodies which are to be driven. The rotary drive mechanism comprises a single motor, an arm structure pivotally supported on an output shaft rotated by the motor, a first rotation transmitting body fixed to the output shaft, a second rotation transmitting body rotatably supported on the arm structure and comprising a first part which is constantly linked to the first rotation transmitting body and a second part, and a third rotation transmitting body having a predetermined rotary load and linked to the second part when the arm structure is in a first rotary position. When the motor rotates in a forward direction, the second part disengages from the third rotation transmitting body and the first part engages and rotationally drives the first body when the arm structure rotates from the first rotary position to a second rotary position. When the motor rotates in a reverse direction, the second part disengages from the third rotation transmitting body and the first part engages and rotationally drives the second body when the arm structure rotates from the first rotary position to a third rotary position.
