Claims

[Claims for Utility Model Registration] (1) A first scanner optical system and a second scanner optical system that moves at half the speed of the first scanner optical system are provided, and a document is scanned by these optical systems. In a document scanning device such as a copying machine, the scanner optical system has one end supported by a sliding member slidingly guided by a guide rod and the other end supported by a guide roller rollingly guided on a guide rail. At least one of the guide roller of the first scanner optical system and the guide roller of the second scanner optical system has a support shaft rotatably supporting the guide roller formed as an eccentric cam, and rotation of the eccentric cam changes the support height of the scanner optical system. A document scanning device characterized in that the document scanning device is configured such that its width can be adjusted. (2) A document scanning device such as a copying machine that includes a first scanner optical system and a second scanner optical system that moves at half the speed of the first scanner optical system, and scans a document using these optical systems. In the scanner optical system, one end is supported by a sliding member slidingly guided by a guide rod, the other end is supported by a guide roller rollingly guided on a guide rail, and the scanner optical system is connected to the guide roller of the first scanner optical system. A support shaft rotatably supporting at least one of the guide rollers of the second scanner optical system is attached to the scanner optical system so that the position of the support shaft can be adjusted in the axial direction, and the support shaft rotatably supports at least one of the guide rollers of the second scanner optical system. The moving surface is formed as an inclined surface whose height gradually changes in the axial direction of the support shaft, and the support height of the scanner optical system can be adjusted by adjusting the position of the support shaft in the axial direction. A document scanning device characterized by:
