Patent number: 11365082Abstract: The present application discloses a post-processing apparatus including a second tray which receives a sheet stack ejected from a first tray, a pushing mechanism including a pushing portion which pushes the sheet stack against the second tray, a motion detector which detects a motion of the pushing mechanism, and a controller including an ejection controller which controls an ejector. When the ejector ejects the sheet stack, the pushing mechanism moves the pushing portion in a first direction away from the second tray. When the ejector finishes ejection of the sheet stack, the pushing mechanism moves the pushing portion in a second direction which is opposite to the first direction. Unless the motion detector detects the motion of the pushing mechanism moving the pushing portion in the first direction when the ejector ejects the sheet stack, the ejection controller executes interruption control of stopping the ejection of the sheet stack.Type: GrantFiled: April 1, 2019Date of Patent: June 21, 2022Inventors: Rina Okada, Terumitsu Noso, Yasunori Ueno

Patent number: 11358824Abstract: A finisher assembly of a multifunction peripheral includes a vertically oriented stapler and a paper transport motor. When the paper transport motor rotates in the forward direction, printed pages from the print engine of the multifunction peripheral are received via a paper chute and a feed assist roller urges the printed pages into a vertical paper accumulation cache basin. Rotation of the paper transport motor also opens a biasing plate allowing the pages to freely enter the cache basin. Once all of the pages of the print job are in the cache basin, the paper transport motor rotates in the reverse direction causing the biasing plate to bias the printed pages, in the cache basin, against a registration surface of the vertically oriented stapler unit. The pages of the print job are stapled together the stapled print job is moved to the paper tray for collection by a user.Type: GrantFiled: February 28, 2020Date of Patent: June 14, 2022Assignee: Toshiba TEC Kabushiki KaishaInventors: Michael W.
