Abstract
A drive force transmission device that causes a plurality of driven members to operate in different operational areas for different operational purposes includes a lead screw and at least one movable member. The lead screw has a threaded portion formed on an outer circumferential surface of the lead screw. The lead screw is rotated about the axis of the lead screw when a drive force is generated. The at least one movable member has an engagement portion that is arranged to engage with the threaded portion of the lead screw. The movable member is moved along the axial direction of the lead screw through the engagement portion guided by the threaded portion when the lead screw rotates. While moving, the movable member associates with the driven members in a state in which the drive force is transmissible from the lead screw to the driven members and operates each of the driven members by the drive force.
