Patent ID: 7408686

Claim:
A manuscript conveyer guide provided in an image-reading unit that reads an image of a manuscript moving on a contact glass plate by using an optical system arranged under the contact glass plate, the manuscript conveyer guide comprising an upper guide being arranged over the contact glass plate and guiding the manuscript that has passed over the contact glass plate in a direction of discharge, wherein: said upper guide has a curved surface and a flat surface in a facing portion to an upper surface of the contact glass plate; the curved surface is positioned on the upstream in the direction which the manuscript is conveyed and the flat surface is positioned on the downstream in the direction which the manuscript is conveyed; and a distance d 2 between the flat surface and the contact glass plate is greater than a distance d 1 between the curved surface and the contact glass plate; further comprising a downstream guide adjacent to the contact glass plate guiding a manuscript that has passed on the contact glass plate to a discharge tray, said downstream guide having an upward incline relative to said contact glass plate; an upstream end of said downstream guide being positioned lower than the upper surface of said contact glass plate, and wherein the distance d 2 is such that the flat surface of said upper guide is above a contact point P of said manuscript on said downstream guide, whereby a deflected portion of said manuscript is prevented from rubbing said upper guide.
