Claim Text:
1. A driving force transmission device, comprising: a first driving member configured to rotate a first rotating member around a first rotation axis, provided coaxially with the first rotation axis, and connectable to the first rotating member and separable from the first rotating member in an axial direction of the first rotation axis; a second driving member configured to rotate a second rotating member around a second rotation axis parallel to the first rotation axis, provided coaxially with the second rotation axis, and connectable to the second rotating member and separable from the second rotating member in an axial direction of the second rotation axis; a moving member movable in a first direction perpendicular to the first rotational axis and the second rotational axis and a second direction opposite to the first direction; and a connection drive section configured to execute, in conjunction with movement of the moving member in the first direction, a separating operation for separating the first driving member from the first rotating member and a separating operation for separating the second driving member from the second rotating member, wherein the moving member includes a first gear portion extending in the first direction, the connection drive section includes: the first transmission section includes a first transmission gear including a second gear portion, the second gear portion engages with the first gear portion of the moving member, the first transmission gear rotates in a third direction around the first rotation axis in association with the movement of the moving member in the first direction, the first transmission section separates the first driving member from the first rotating member in association with the rotation of the first transmission gear in the third direction, the second transmission section includes a second transmission gear, the second transmission gear rotates around the second rotation axis in a fourth direction in association with the rotation of the first transmission gear in the third direction so as to separate the second driving member from the second rotating member, the fourth direction is opposite to the third direction, the connecting section rotates the second transmission gear in the fourth direction in association with the rotation of the first transmission gear in the third direction, the connecting section includes: the linking member includes: the second fulcrum portion is inserted through the elongated opening, in the first transmission section, the first transmission gear is rotated in the third direction by the moving member from a first angle at which the first driving member is connected to the first rotating member to a third angle through a second angle at which the first driving member is separated from the first rotating member, in the connecting section: the second transmission gear rotates in the fourth direction around the second rotation axis in association with the rotation of the first transmission gear from the second angle to the third angle so as to separate the second driving member from the second rotating member, and a time difference occurs between the separating operation for the first driving member and the separating operation for the second driving member.
