Abstract:
A printer comprising:a paper supply section for supplying a recording paper therefrom; a feed roller pair for nipping and conveying said recording paper along a paper transport path; a printing head for printing an image on said recording paper in synchronism with conveying movement of said recording paper; an aligning device disposed in said paper transport path between said paper supply section and said printing head, said aligning device pushing side edges of said recording paper in a lateral direction to said paper transport path to align said recording paper with said paper transport path; a path size switching device disposed between said paper supply section and said aligning device, said path size switching device being switchable between a limiting position and a widening position; and a system control means for switching said path size switching device to said limiting position while said recording paper is being conveyed in a paper supply direction from said paper supply section toward said printing head, for limiting the paper transport path in a direction of thickness of said recording paper, and for switching said path size switching device to a widening position while said aligning device is being activated and while said recording paper is being conveyed in a reverse direction to said paper supply direction, for widening said paper transport path in the direction of thickness of said recording paper, thereby to allow said recording paper to make a loop between said paper supply section and said aligning device.
