[Second embodiment of route forming unit]
A second embodiment of the route forming section 60 included in the relay conveyance device 50 will be described with reference to FIG. 3. In order to show the features of the structure, FIG. 3 shows a side view of the path forming part 60, unlike the cross-sectional view of FIG.
In FIG. 3, a second embodiment of the path forming section 60 is designated by the reference numeral 60B. In the embodiment described with reference to FIG. 3 and subsequent figures, the same components as those shown in FIG. 2 are denoted by the same reference numerals, and redundant explanation will be avoided.
In FIG. 3, the path forming section 60B is composed of a paper guide member 65. The paper guide member 65 has a rotation shaft 65a that constitutes a first rotation fulcrum, and by rotating in the XZ plane about the rotation shaft 65a, the ejection section 59 moves to the path forming section 60B.

[Third embodiment of route forming unit]
A third embodiment of the route forming section 60 included in the relay conveyance device 50 will be described with reference to FIG. 4. Similar to FIG. 3, FIG. 4 also shows the side surface of the path forming portion 60, unlike the cross-sectional view of FIG. 2, in order to show the features of the structure. In FIG. 4, a third embodiment of the path forming section 60 is designated by the reference numeral 60C.

Thereby, the path forming part 60C is rotatable about the rotation axis 70a and movable in the X-axis direction.

A second paper guide member 71 is arranged downstream of the first paper guide member 70 . The first paper guide member 70 and the second paper guide member 71 are connected by a connecting portion 72. The second paper guide member 71 is connected to the connecting portion 72 via the rotation shaft 71a, which is a second rotation fulcrum, so that it can rotate about the rotation shaft 70a in the XZ plane. As the second paper guide member 71 rotates, the discharge section 59 is displaced in the Z-axis direction. In FIG. 4, arrows R1b and R2b indicate the rotation direction of the second paper guide member 71.
In this way, by the rotation of the first paper guide member 70 and the rotation of the second paper guide member 71, the discharge section 59 is displaced in the Z-axis direction, which is the direction intersecting the moving direction of the path forming section 60C. Therefore, when connecting the printer 1 and the post-processing device 30, the paper ejecting direction from the discharging unit 59 is determined by the paper receiving position in the post-processing device 30, specifically between the receiving member 38 and the receiving member 39. It is possible to prevent the camera from moving too far away from its location.
That is, in FIG. 4, the first paper guide member 70 faces toward the lower left, which is a direction away from the position between the receiving members 38 and 39. On the other hand, the second paper guide member 71 faces toward the upper left in FIG. 4, which is the direction between the receiving member 38 and the receiving member 39. By rotatably connecting the plurality of path forming parts to each other in this manner, the paper can be appropriately directed between the receiving member 38 and the receiving member 39.
