Abstract:
A document reading device for applying light to a document placed on platen glass so as to read an image formed on the document. The device is provided with a light-screen. The width of the light-screen can be changed according to the document size in such a way that it is also possible to change the amount of light which can pass through the light-screen from a light source to be applied to the platen glass. With this arrangement, a local temperature increase in the platen glass can be inhibited during sequential document-reading.
