Abstract

A printer comprises a rotatable platen for supporting a sheet and a printhead which is capable of moving along the platen to print data on the sheet. A paper bail shaft supports paper bail rollers rotatably so as to be faced to the platen. A printhead retreating unit makes the printhead retreat to a position opposed to one end of the platen at the time of a paper feed operation. Arms serve as a paper bail retreating unit to separate the paper bail rollers from the platen at the time of the paper feed operation by displacing one end of the paper bail shaft a greater distance from the platen than the other end where the printhead is retreated.
