Description

Post-processing device and image forming apparatus Technical Field The present invention relates to a post-processing apparatus and an image forming apparatus. Background Patent document 1 discloses a post-processing apparatus including a1 st stapling unit 90 that staples paper and moves a1 st gear 97 while rotating, a 2nd stapling unit 70 that staples paper and moves a 2nd gear 77 while rotating, a common path 521 that is a path along which the 1 st stapling unit and the 2nd stapling unit move, a1 st rack 54 that is provided along the common path and meshes with the 1 st gear, and a 2nd rack 53 that is provided along the common path and is provided on the opposite side of the common path from the 1 st rack and meshes with the 2nd gear. Patent document 1 Japanese patent application laid-open No. 2019-167194 Disclosure of Invention The invention aims to provide a post-processing device and an image forming device which can obliquely bind by obliquely rotating a binding device even if a guide rail for moving the binding device is in a straight line. The post-processing device according to claim 1 of the present invention includes a stapling device that performs stapling processing on a sheet bundle, a guide rail that moves the stapling device, and a rotation mechanism that is disposed adjacent to the guide rail and rotates the stapling device that moves on the guide rail in accordance with the movement. In the post-processing apparatus according to claim 2 of the present invention, in the post-processing apparatus according to claim 1, the stapling apparatus is rotatably mounted on a base that moves on the guide rail via a rotary table, and the rotating mechanism accommodates a guide provided to the stapling apparatus in a guide mechanism in association with the movement of the stapling apparatus, and moves the accommodated guide along the guide mechanism, thereby rotating the stapling apparatus obliquely.
