Claim Text:
1. A drive transmission device comprising: a first output gear and a second output gear which are rotatable about the same rotational axis; and a single intermediary member to be rotated about the rotational axis by a driving source, wherein said intermediary member is provided between said first output gear and said second output gear with respect to an axial direction of the rotational axis, wherein said intermediary member moves in a first axial direction of the rotational axis to rotate in engagement with said first output gear when the driving source rotates in a first direction, and moves in a second axial direction of the rotational axis opposite to the first axial direction to rotate in engagement with said second output gear when the driving source rotates in a second direction opposite to the first direction, and wherein said intermediary member includes a first ratchet tooth having a first ratchet surface for transmitting drive to said first output gear and a second ratchet surface for moving said intermediary member toward said second output gear, and includes a second ratchet tooth having a third ratchet surface for transmitting drive to said second output gear and a fourth ratchet surface for moving said intermediary member toward said first output gear.
