A buffer saddle is provided separately from the main saddle, on an opposite side of the center-folder across the main saddle. The pile of sheets saddle-stitched on the main saddle is placed on the buffer saddle. When viewed from above, the buffer saddle is movable in a direction separating from the main saddle that is a reverse direction to the center-folder, and in a direction orthogonal to the direction separating from the main saddle. A sheet processing device is arranged in the orthogonal direction where the buffer saddle is movable. ## Claims ### Claim 1 A sheet processing device comprising: a first saddle on which sheets center-folded by a center-folder are to be placed; a second saddle that is provided separately from the first saddle on an opposite side of the center-folder across the first saddle, allows a pile of sheets saddle-stitched on the first saddle to be placed thereon, and is movable in a direction separating from the first saddle that is a reverse direction to the center-folder and in a direction orthogonal to the direction separating from the first saddle, viewed from above; and a post processor that is arranged in the orthogonal direction where the second saddle is movable, and performs a post-processing on the pile of sheets. ### Claim 2 (depends on 1) The sheet processing device according to claim 1, wherein while a folding direction of the center-folded pile of sheets is fixed, the pile of sheets are moved from the center-folder through the first saddle and the second saddle to the post processor. ### Claim 3 (depends on 1) The sheet processing device according to claim 1, wherein when the second saddle feeds the pile of sheets to the post processor with the pile of sheets placed on the second saddle, the second saddle moves in the direction separating from the first saddle, and thereafter moves in the direction orthogonal to the direction separating from the first saddle, and when the second saddle delivers the pile of sheets to the post processor and thereafter returns to a receiving position for receiving the pile of sheets from the first saddle, the second saddle moves linearly from a delivering position to the post processor, to the receiving position from the first saddle. ### Claim 4 (depends on 1) The sheet processing device according to claim 1, wherein the post processor includes a cutter that trims an edge portion of the pile of sheets. ### Claim 5 (depends on 1) The sheet processing device according to claim 1, wherein. a sheet loader that loads the pile of sheets post-processed by the post processor is arranged above the second saddle. ### Claim 6 (depends on 1) An image forming system comprising: an image forming unit that forms an image on a sheet; and the sheet processing device according to claim 1 that receives the sheet on which the image is formed by the image forming unit.
