ABSTRACT:
A paper bail in a printer having a platen includes two bail levers rotatably mounted on the printer and pressed toward the platen by a spring. An elongate bail plate is formed as a flat metal sheet having a L-shaped section, one side of which extends substantially transverse to a line connecting the bail plate with a rotational axis of the bail levers. A bail roller on the bail plate is mounted thereon by an elastic member capable of permitting only axial movement of the bail roller when the bail roller is out of contact with the platen, and permitting only rotational movement of the bail roller when the bail roller is in contact with the platen.
