Image scanning and printing system having a common paper feeding passage

摘要

A scanner printer includes a scanner portion for reading written information on an original manuscript paper and a printer portion for printing written information on printing paper, both of which are integrally combined within a single casing. The respective paper feeding into the scanner portion and the printer portion is performed through a common feeding passage. Thus, the overall dimension of the scanner printer can be downsized. A pointer directs the original manuscript and the printing paper into an original manuscript passage and into the printer portion, respectively. Hence, wear an on a surface of a photo-sensitive drum of the printer portion can be greatly reduced thus maintaining accurate and sharp printing characteristics.
