Patent number: 11708233Abstract: A sheet stop mechanism includes a sheet stopper and a support mechanism. The sheet stopper is formed on a sheet stacking surface. The support mechanism supports the sheet stopper to be rotatable between a stored state and a standing state, wherein in the stored state, the sheet stopper is stored in the sheet stacking surface, and in the standing state, the sheet stopper stands from the sheet stacking surface diagonally upward toward a downstream in the sheet discharge direction. When the sheet stopper is in the standing state, the support mechanism supports the sheet stopper in such a manner that an angle formed between the sheet stopper and the sheet stacking surface becomes small as sheets stacked on the sheet stacking surface increase in number.Type: GrantFiled: September 29, 2020Date of Patent: July 25, 2023Assignee: KYOCERA Document Solutions Inc.Inventors: Takeshi Yoshida, Takeshi Iketani
