Document conveying apparatus, image reading apparatus and image forming apparatus

An image reading apparatus comprising:

• a document conveying apparatus, including
• a document tray on which a document is placed,
• a feeding member configured to feed the document placed on the document tray in a feeding direction,
• a conveying portion configured to convey the document fed by the feeding member, and
• a discharge tray which is disposed below the document tray and onto which the document conveyed by the conveying portion is discharged,
• wherein the document tray includes
• an upper tray member configured to support the document,
• a lower tray member disposed to cover an underside of the upper tray member,
• a movable tray member configured to move, with respect to the upper tray member, in a width direction orthogonal to the feeding direction between a first position in which the movable tray member supports the document together with the upper tray member and a second position in which the movable tray member is retracted from the first position into below the upper tray member,
• a first regulating member provided on the movable tray member and configured to regulate one side edge of the document supported by the document tray in the width direction,
• a second regulating member provided on the upper tray member and configured to regulate the other side edge of the document supported by the document tray in the width direction, and
• a driving portion configured to move the upper tray member and the movable tray member integrally to a raised position in which the document placed on the document tray contacts the feeding member and a lowered position in which the document placed on the document tray is separated from the feeding member,
• wherein the document tray includes a shutter configured to cover a gap created between the upper tray member and the lower tray member, the gap being created by the upper tray member and the movable tray member being moved from the lowered position to the raised position and the movable tray member being moved from the first position to the second position;
• and
• an image reading portion configured to read an image of the document conveyed by the document conveying apparatus.
