を特徴とする画像読取装置。 The document table is supported under a transparent document table so as to be movable in the sub-scanning direction, and the document table has a tilt angle of 45.
A first traveling body having elongated reflecting mirrors in the main scanning direction facing each other at an angle of 90 degrees is provided, and the first traveling body is supported movably in the sub-scanning direction on the reflection optical axis of the first traveling body and is elongated in the main scanning direction at an included angle of 90 degrees. A second traveling body having two reflecting mirrors is provided, a light receiver is fixedly disposed on the reflection optical axis of the second traveling body, and the amount of movement of the second traveling body is determined by the movement of the first traveling body. In an image reading device in which a scanning optical path with a constant optical path length from the surface of the original document mounting table to the light receiver is formed as half of the amount, a drive belt stretched in the sub-scanning direction and connected to the first traveling body is provided. A guide rail is provided that is elongated in the sub-scanning direction and is disposed parallel to and opposite to the tensioning portion of the drive belt, and is rotatably supported between the guide rail and the drive belt to support the second traveling body. What is claimed is: 1. An image reading device comprising: a driven wheel connected to a driven wheel;
