て、挟持した受信用紙S2を送り出す。Below the main gear 4, there is provided a drive gear 3 which is connected to a drive motor (not shown) to rotate, and the movable levers 2A and 2B connected to the document feed table (not shown) are rotated about the center O1. In the state of FIG. 1 in which the main gear 4 is tilted upwards,
Is rotated downward, meshes with the drive gear 3, and is rotated about the center O2. In this state, the drive roller 1 which is pivoted downward together comes into contact with the lower driven roller 7 as shown in FIG. 4 and rotates around the center O2 together with the main gear 4 to send out the sandwiched receiving sheet S2.

用紙S2と同方向へ送り出す。Both the moving levers 2 are operated by operating the document feed table.
When the A and 2B are tilted downward about the center O1 (FIG. 2), the main gear 4 pivots upward and disengages from the drive gear 3, and the sub gear 5 meshes with the drive gear 3 instead. Since the main gear 4 is rotated via the sub gear 5, the center O is rotated in the direction opposite to that at the time of the downward movement end.
Rotate around 2. In this state, the drive roller 1 is
As shown in FIG. 3, the driven original 6 comes into contact with the upper driven roller 6 and rotates together with the main gear 4 about the center O2 to send out the sandwiched transmission original S1 in the same direction as the reception paper S2.
