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.
Claims18
A paper-feeding mechanism for a compact printer comprising paper-feeding roller means, a driven wheel for transmitting rotary motion to said roller means, a driving wheel driving said driven wheel, said driven wheel having first and second rotary motion transmission means, said driving means having means for cooperative interengagement with said first and second transmission means, said first and second transmission means being adapted to drive said driven wheel at different rotary speeds when engaged by said interengagement means, and means for selectively engaging said interengagement means with one of said first and second transmission means for selecting the rotary drive speed of said driven wheel.
