Patent ID: 7672026

Claim:
A sheet presser, comprising: two pivot shaft portions fixedly disposed substantially coaxially with each other and substantially parallel to a sheet of a document as conveyed in a predetermined direction; a pressing member pivotably mounted on the pivot shaft portions; and a biasing member which biases the pressing member around the pivot shaft portions in a direction to press the sheet, wherein the pressing member has a pair of elongate bearing bores, each of which is long in a direction substantially perpendicular to a surface of the sheet, and which are formed in respective portions which are distant in a lateral direction of the pressing member to bear the respective pivot shaft portions; and the biasing member biases the pressing member such that at least one of the pivot shaft portions is held in contact with a remote end of the corresponding bearing bore which is one of opposite ends of the bearing bore and away from the sheet, so that an acute angle is formed, between the predetermined direction of conveyance of the sheet and a portion of the pressing member that contacts the sheet, when the pressing member is held within a predetermined range.
