PROBLEM TO BE SOLVED: To reduce the size of a recording material processing device or the like including a binding mechanism unit and provided with a guide member guiding a recording material and displaceable in a direction away from a recording material transport route.SOLUTION: A sheet guide member 80 is provided rotatably around a hinge 81 arranged deep in a first post-processing device. Upon rotation of the sheet guide member 80 around the hinge 81, the sheet guide member 80 arrives onto a moving route of a staple head 51, and an opening is formed in a portion indicated by reference symbol 5A. A user is thereby accessible to a third sheet transport route R3 from a front side of the first post-processing device via this opening. |
