ABSTRACT:
A paper feeding apparatus for the printer having an intermittent mechanism between a driving motor and both a paper feed roller and a platen. The intermittent mechanism allows both the platen and the paper feed roller to rotate simultaneously and also allows only the platen to rotate while the paper feed roller is suspended, so that a sheet of printing paper is set straight along the platen. When the rotational direction of the driving motor is reversed to reverse that of the platen, the driving motor stops rotating for a limited period. Under such conditions the sheet is fed properly in response to the rotation of the platen, being free from the inertia force of the sheet and from the platen's vibration.
