Patent number: 9796542Abstract: A sheet feeding device having sheet feed tray configured to support multiple sheets be movably inserted to a main body. A sheet feed roller is configured to contact the sheet supported by the sheet feed tray and rotate to apply a feeding force to feed the sheet in a sheet feed direction. The sheet feed roller is configured to contact the sheet feed tray when there is no sheet on the sheet feed tray. A push latch mechanism is arranged on a downstream side with respect to the sheet feed roller in the sheet feed direction. A state of the push latch mechanism is alternately switched between an engaged state and a disengaged state every time when a pressing force is applied to the push latch mechanism. A first spring is configured to exert an elastic force to move the sheet feed tray toward a near side.Type: GrantFiled: March 28, 2016Date of Patent: October 24, 2017Assignee: Brother Kogyo Kabushiki KaishaInventors: Yukio Shiohara, Yohei Hashimoto, Masamitsu Ukai, Hirotaka Mori, Noriyuki Kawamata, Masahito Saeki, Hiroyuki Okuchi, Makoto Souda
