ABSTRACT:
A printer apparatus includes: a platen roller around which paper sheets wind; a printing structure arranged for being drawn near to and away from the platen roller; a plurality of winding support members circumferentially disposed around the platen roller, for guiding a paper sheet to wrap around the roller; a sheet feed guide disposed in proximity to the printing structure and being pivotable substantially along the circumference of the roller; and a diverting mechanism for letting the sheet feed guide escape to a position such that it does not interfere with the printing structure in a print mode. The sheet feed guide is linked with a lever that pivots in a plane substantially perpendicular to the rotation axis of the platen roller, the lever having a fore-end protuberance.
