Patent number: 9126784Abstract: A paper feeding device includes a pressing member, a restricting mechanism, and an interlocking mechanism. The pressing member is movable up and down between a pressing position and a release position. The pressing position causes a pressure to a paper sheet against the feed roller. The release position causes a release of the pressure. The restricting mechanism is movable between a restricting position and a removal position. The restricting position causes a restriction on moving up of the pressing member to the pressing position. The removal position causes a removal of the restriction. The interlocking mechanism is configured to move the restricting mechanism to the removal position in interlock with rotation of the feed roller.Type: GrantFiled: May 9, 2014Date of Patent: September 8, 2015Assignee: Sharp Kabushiki KaishaInventors: Kohji Aoki, Haruhisa Furumoto
