Patent number: 5580038Abstract: A sheet post-treating apparatus includes a stapler disposed along a path to a discharge port. A pile of sheets to be stapled at two locations along a lateral edge is driven toward the discharge tray until the downstream stapling location is at the stapler. The movement of the pile of sheets is then reversed to bring the upstream stapling location to the stapler. The movement of the pile of sheets is then again reversed to discharge the now stapled pile.Type: GrantFiled: April 17, 1995Date of Patent: December 3, 1996Assignee: Nisca CorporationInventors: Kimihiko Furuya, Misao Kobayashi, Hideki Mimura, Takehiko Saitou, Masahiro Kouno
