PRINTING SYSTEM, SHEET TREATMENT SYSTEM, AND SHEET PASSAGE SWITCHING DEVICE

摘要

A path switching unit is provided which is capable of switching a sheet travel path between a first path and a second path parallel to each other, and capable of reversing a sheet that passes along the first path. A first input unit that introduces a sheet into the first path and a second input unit that introduces a sheet into the second path are adjacent to each other. A first output unit to which a sheet that has traveled along the first path is output and a second output unit to which a sheet that has traveled along the second path is output are also adjacent to each other.
