露光光学装置。[Claims for Utility Model Registration] (1) A copy original placed approximately horizontally is scanned by a first mirror mounted on a full-rate mirror carriage, and an image of the original is scanned by the first mirror and the half-rate mirror carriage. In an exposure optical device for a copying machine, which forms an image on a photoreceptor using a plurality of mirrors including second and third mirrors mounted on a rate mirror carriage and an imaging lens, in the third mirror: A fourth mirror is provided that reflects light traveling in a substantially horizontal direction so as to travel downward on the side of the photoconductor before reaching the top of the photoconductor, and the half-rate mirror carriage is configured to fifth and sixth mirrors are provided, which are always located laterally away from the photoreceptor and its peripheral equipment, and which guide the light reflected downward by the fourth mirror onto the photoreceptor from the lower side. An exposure optical device for a copying machine characterized by the following. (2) The exposure optical device for a copying machine according to claim 1, wherein the imaging lens is disposed in an optical path going downward from the fourth mirror.
