    摘要： A document reading device comprising a document stand having a document placing surface and an optical reading means for optically reading the surface of a document placed on the document placing surface. The device further comprises a guide member defining a guide passage extending in a direction toward and away from the document placing surface, an oscillating member mounted such that its one end can reciprocate freely along the document placing surface in a predetermined scanning direction and in a direction opposite to it and the other end can freely reciprocate along the guide passage, and a driving source for oscillating the oscillating member which is capable of moving said one end of the oscillating member at a substantially constant speed'in the scanning direction. The optical reading means is provided in the oscillating member. While said one end of the oscillating member is moved in the scanning direction at said substantially constant speed, the optical distance between the surface of the document placed on the document placing surface and the optical reading means is maintained substantially constant, and the optical reading means scans the surface of the document.
