Scanning and printing apparatus.

摘要

In a scanning and printing apparatus such as a copier or facsimile machine, the same driving system (11-15) moves the scanning unit (21-23) and transports paper (35) through the printing unit (41-47). One edge of the paper (35) is held by a clamping mechanism (31) that is driven together with the scanning unit. In a copier, signals from the scanning unit can be sent directly to the printing unit for simultaneous scanning and printing which automatically synchronises the scanning and printing speeds. Alternatively, the signals can be temporarily stored, and scanning and printing can be performed in opposite directions of motion. For color scanning and printing, the scanning unit has filters (64) that spectrally match the inks in the printing unit. The apparatus is compact and economical because it has only a single driving mechanism and requires minimal signal interfacing.
