Abstract

A lead-in path through which a sheet is led in; a first branch path and a second branch path which branch from the lead-in path; a first switchback path which extends from the first branch path; a second switchback path which extends from the second branch path; a first joining path and a second joining path through which the switched-back sheet is transported; and a lead-out path which extends from a joining point at which the first joining path and the second joining path join with each other, are provided. The lead-out path passes through between the first switchback path and the second switchback path. A first connection point at which the first switchback path and the first joining path are connected to each other is disposed above a second connection point at which the second switchback path and the second joining path are connected to each other.

First claim

What is claimed is:

1. A transport apparatus comprising:
a housing which includes a plurality of paths;
a lead-in path through which a medium is led into the housing;
a first branch path and a second branch path which branch in directions different from each other from a branch point which becomes a downstream end of the lead-in path, in a transport direction in which the medium led in from the lead-in path is transported;
a guiding portion which guides the medium by selectively switching the medium that is transported through the lead-in path to be transported to any one of the first branch path and the second branch path;
a first switchback path which is provided to extend downward in a vertical direction from the downstream end of the first branch path, and in which the medium is switched back;
a second switchback path which is provided to extend downward in a vertical direction from the downstream end of the second branch path, and in which the medium is switched back;
a first joining path through which the medium switched back by the first switchback path is transported;
a second joining path through which the medium switched back by the second switchback path is transported; and
a lead-out path which extends from a joining point at which the downstream end of the first joining path and the downstream end of the second joining path join with each other,
wherein the lead-out path is provided to pass through between the first switchback path and the second switchback path and extend in order to detour the downstream end of the first switchback path,
wherein a first connection point at which an upstream end of the first switchback path and an upstream end of the first joining path are connected to each other is disposed above a second connection point at which an upstream end of the second switchback path and an upstream end of the second joining path are connected to each other in the vertical direction, and
wherein a downstream side in the second switchback path is configured of a guide portion provided to extend lower in the vertical direction than the detour portion of the lead-out path.

2. The transport apparatus according to claim 1 ,
wherein the first connection point is positioned below the branch point in the vertical direction.

3. The transport apparatus according to claim 1 ,
wherein the lead-in path is provided to diagonally extend to intersect the vertical direction.

4. The transport apparatus according to claim 3 ,
wherein the lead-in path is provided to include a portion which is above the housing in the vertical direction to penetrate the inside and the outside of the housing.

5. The transport apparatus according to claim 4 ,
wherein the downstream end of the lead-out path extends toward a side opposite to the side on which the lead-in path penetrates the housing, and the first connection point and the second connection point are positioned near the downstream end of the lead-out path with respect to the branch point.

6. The transport apparatus according to claim 1 ,
wherein an opening portion is formed at a part of a side wall of the housing.

7. The transport apparatus according to claim 1 ,
wherein the second switchback path extends to pass through a lower part of a path which is positioned at the lowermost part of the lead-out path, in the vertical direction.
