ABSTRACT:
A paper-feeding mechanism of a compact printer is provided. The mechanism has a driven wheel which transmits rotation to a paper-feeding roller and a driving wheel which drives the driven wheel. The driving wheel has first and second sets of gear teeth for engagement with teeth on the driven wheel. The driving wheel is axially displaceable to provide for driving with the first set of gear teeth at a normal paper feed rate and also by the second set for driving at a rapid paper feed rate. A solenoid-operated rate-selection lever serves to select either of the driving speeds. A cam attached to a power wheel which drives the driving wheel serves to return the mechanism from rapid to regular paper-feeding.
