Abstract:
1. A drive switching mechanism comprising: a first transmission element train that transmits a driving force from a drive source that rotates in a predetermined direction; a second transmission element train that is connectable to the first transmission element train and that transmits the driving force to a rotatable body; a third transmission element train disposed in an indirect path connecting an element of the first transmission element train to an element of the second transmission element train; a connection/disconnection element disposed at one of a position between the first and second transmission element trains and a position in the third transmission element train, the connection/disconnection element connecting or disconnecting a drive transmission path depending on whether or not current is applied thereto; and a rotation restraining element disposed at the other of the position between the first and second transmission element trains and the position in the third transmission element train, the rotation restraining element being drivenly rotated, when the drive transmission path is disconnected by the connection/disconnection element, on the basis of a driving force transmitted from the first transmission element train and selecting a drive transmission path that is different from the drive transmission path disconnected by the connection/disconnection element, and the rotation restraining element stopping being drivenly rotated, when the drive transmission path is connected by the connection/disconnection element, on the basis of driving forces transmitted from the first and second transmission element trains and selecting the drive transmission path connected by the connection/disconnection element.
