Paper feeder

Abstract

A paper width of a sheet of paper is input into a paper width setting section. In case of defining a non-print area at a fore end of the paper, a paper bail roller is manually separated from a platen to output a detection signal A from a paper bail switch. In this case, a paper feeding motor is controlled to be driven by a control device, thereby feeding the paper until the fore end of the paper reaches the paper bail roller. On the other hand, in case of starting printing from the fore end of the paper, an operating section is operated to output a command signal B therefrom. In this case, only when the paper width input into the paper width setting section is determined to be less than a predetermined value by the control device, the paper feeding motor is controlled to be driven by the control device, thereby feeding the paper until the fore end of the paper reaches a position opposed to the printing head, and a centering device is controlled to be driven by the control means, thereby moving a carrier to a transverse center of the paper, so as to suppress separation of opposite side portions of the paper from the platen.
