Claims

[Claims for Utility Model Registration] (1) Transparent original projection in an original reading device consisting of a projection device main body equipped with an illumination optical system and an imaging optical system, and a reflective surface unit section equipped with a reflective surface and a connecting optical system. In the device, the reflective surface in the reflective surface unit section is held fixed at a predetermined angle, and the reflective surface unit section including the reflective surface is covered with a cover member having a front opening that serves as an optical path guided to the reflective surface. What is claimed is: 1. A transparent original projection device in an original reading device, characterized in that: (2) The transparent original projection device in the original reading device according to item 1, further comprising a locking means for coupling the reflective surface unit portion and the projection device main body. (3) A transparent document in the document reading device according to item 1, wherein the coupling optical system in the reflective surface unit section is mounted so as to be movable relative to the reflective surface fixedly held at a predetermined angle. Projection device.
