PURPOSE:To execute easily the fine adjustment of a position of an inmirror lens by providing an image forming member so as to be freely attachable and detachable at a position separated by the same length as an optical length extending from the reflection mirror surface of the third reflection mirror to a rotary drum. CONSTITUTION:When positioning an inmirror lens 144, an image forming member 170 is installed to the prescribed position in a state that the right side wall and a partition plate 126 of a housing 100, and the third reflection mirror 146 are not installed. As a result, the image of an original placed on a transparent plate 102 is projected onto an image forming member 170, and this image forming member 170 is positioned in the vicinity of the right side wall of the housing 100, and also constituted of a translucent member such as glass, therefore, the original image projected to the surface of the image forming member 170 is observed easily from the rear side of the image forming member 170. Accordingly, the position of the inmirror lens 144 is finely adjusted easily, observing the original image projected to the surface of the image forming member 170. |
