Abstract
Abstract A facsimile device has optical reader unit, an original transport unit, a printing unit, and a base unit. The optical reader unit comprises a light source for illuminating an original document, and an image reading element for receiving and reading the light reflected from the original document. The original transport unit comprises a feed roller and original guides for transporting the original document to an original reading position of the optical reader unit. The printing unit comprises a printer head and a flexible member which presses the printer head on a recording paper to be copied. The base unit comprises a recording paper holder and a platen. The base unit is provided for supporting each of the optical reader unit, the original transport unit and the printing unit.
