Sheet storing cassette and image forming apparatus therewith

A sheet storing cassette, comprising:

• a cassette base which can be inserted in and drawn out from an apparatus main body and which stores sheets;
• a sheet stacking plate whose end part on an upstream side in a sheet feeding direction is pivotably supported on a bottom face of the cassette base and on whose top face the sheet is placed;
• a cursor rail which is on the bottom face of the cassette base and which extends along the sheet feeding direction;
• a regulation cursor which is provided movably along the cursor rail, the regulation cursor having an engaging portion and a first regulating portion which forms a first sheet regulating face for positioning the sheet placed on the sheet stacking plate in the sheet feeding direction;
• a plurality of engaged portions which are provided at standard-size positions corresponding to a plurality of standard sheet sizes in the cursor rail to mesh with the engaging portion when the regulation cursor is arranged at one of the standard-size positions;
• and
• an adjustment member which is attachable to and removable from the regulation cursor and which has a second regulating portion that offsets, when the adjustment member is attached to the regulation cursor arranged at one of the standard-size positions, the first sheet regulating face to a second sheet regulating face corresponding to a non-standard size sheet smaller in the sheet feeding direction than a standard size corresponding to the one of the standard-size positions, and
• a plurality of the adjustment members corresponding to the sheets in a plurality of the non-standard sizes,
• wherein
• one of the plurality of adjustment members is selectively fitted to the regulation cursor, and
• the standard size without offsetting of the first sheet regulating face and the non-standard size with offsetting of the first sheet regulating face to the second sheet regulating face are indicated on each of the adjustment members.
