A sheet feeder 3 includes a stopper member 532 which is a member located in a sheet feeding route and supported on a supporting body 531 rotatably about a first rotational pivot point and the posture of which is changed among a restricting posture in which a contact end portion 538 comes into contact with a leading end SU of a sheet S in a feeding direction to restrict the position of the leading end SU in the feeding direction before a feeding operation of feeding the sheet S by a feeding mechanism 32, a feed allowing posture which is assumed during the feeding operation and in which the contact end portion 538 is separated from the leading end SU in the feeding direction in a first direction F in which the sheet S is fed, and a rotational posture reached from the feed allowing posture by the rotation of the stopper member 532 about the first rotational pivot point so that the contact end portion 538 faces in a second direction opposite to the first direction. The second direction is a direction in which the sheet S is pulled out from the feeding mechanism 32 when a jam occurs in the feeding mechanism 32. |
