Abstract
An apparatus for delaying the closing of a printer paper bail so that paper positioned for the first line of printing at the top of the paper will advance in the paper path to a position where the paper bail can close on it. The apparatus mounts on a conventional paper bail assembly and has a sector cam which rotates to a position between its axis of rotation and the platen thereby restraining the closing of the paper bail. It is preferable that the sector cam contact the drive gear of the platen. When the platen rotates for feeding the paper through the paper path, frictional contact between the sector cam and the platen gear causes the sector cam to rotate to a position where the sector is no longer between its axis of rotation and the platen thereby permitting the paper bail which is under spring tension to close.
