Patent number: 11365073Abstract: According to one embodiment, a manual sheet feeding device includes a pressure plate, a first displacement member, a first input member, a second displacement member, a second input member, a coupling member, a restricting member, and an elastic member. The first displacement member displaces the plate from a first side to a pressure and a release position. The first input member displaces the first displacement member to a first and a second position. The second displacement member displaces the plate from a second side to the pressure and the release position. The second input member displaces the second displacement member to a third and a fourth position. The coupling member gives the second input member a second displacement amount larger than a first displacement amount. The restricting member restricts a displacement amount of the second input member. The elastic member elastically deforms when the amount of displacement is restricted.Type: GrantFiled: August 13, 2019Date of Patent: June 21, 2022Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventor: Shoichi Dobashi
