ABSTRACT:
Apparatus for controlling the feeding of paper about a printer platen. Controlled are paper aligning, rear roller feeding, front roller feeding and paper bail operation. The apparatus is primarily made up of a rocker button, reed switches, a drive motor, a cam gear, a comb, and a paper bail. Upon operator manipulation of the rocker button, the drive motor is turned on for rotating the cam gear. Rotation of the cam gear effects bi-directional rotation of the comb and a paper bail arm carrying the paper bail. Rotation of the comb in a first direction results in (1) a rear feed roller being displaced from the platen to provide a feeding path for paper when inserted into the printer, and (2) a paper aligner being positioned for aligning the paper. Rotation of the comb in a second direction results in the rear feed roller causing engagement of the paper and platen and the paper aligner being brought out of the feeding path of the paper. Rotation of the paper bail arm in a first direction causes the paper bail to be displaced from the platen. Rotation in a second direction results in the paper bail causing engagement of the paper and platen.
