Abstract:
1. A sheet storage cassette, comprising: a cassette base where sheets are stored; a sheet stacking plate on an upper surface of which sheets are placed, and an upstream-side end portion of which in a feeding direction of the sheets is rotatably supported at a bottom of the cassette base; a lift portion that moves the sheet stacking plate up and down between a lower limit position that is parallel to the bottom of the cassette base and that allows the sheets to be set on the sheet stacking plate and a sheet feeding position that allows the sheets to be fed out; and a pair of width adjustment cursors provided one on each side in a sheet width direction perpendicular to the feeding direction of the sheets, to be reciprocatingly movable in the sheet width direction, the sheet storage cassette being insertable and withdrawable with respect to a body of an image forming apparatus, wherein at least one of the width adjustment cursors includes: wherein when the sheet stacking plate is located at the lower limit position with respect to the cassette base, the pressed portion is pressed by the sheet stacking plate into a pressed state to cause the restriction portion to swing in a direction of the first position against a biasing force of the first biasing member, and when the sheet stacking plate rises up to the sheet feeding position, the pressed state of the pressed portion is released and the restriction portion is caused to swing in the direction of the second position by the biasing force of the first biasing member.
