A conveyance path is formed inside the frame to connect the document tray and the discharge tray. The frame contains a conveying structure to convey the original document along the conveyance path; a transparent support member located below the conveyance path to support the original document; a scanning member located below the transparent support member, the scanning member having a scanning position in which the scanning member scans the original document when being located on the transparent support member; and a pressing member disposed above the transparent support member and facing the scanning member for pressing the original document onto the transparent support member.
