Abstract:
1. A drive transmission unit, comprising: a first input rotary body to rotate in a first direction; a second input rotary body; a rotation input shaft to bear rotatably and coaxially the first input rotary body and the second input rotary body, a first switching device disposed on the rotation input shaft to switch between a power transmitting state and a non-transmitting state between the first input rotary body and the second input rotary body; a first output rotary body disposed in a radial direction of the first input rotary body, to receive from the first input rotary body a driving force in a second direction opposite the first direction; a second output rotary body disposed in the radial direction of the second input rotary body, to receive from the second input rotary body a driving force in the same direction of rotation as that of the second input rotary body; a rotation output shaft to bear rotatably and coaxially the first output rotary body and the second output rotary body, and a second switching device disposed on the rotation output shaft to switch between the power transmitting state and the non-transmitting state between the first output rotary body and the second output rotary body.
