Abstract
Disclosed is a sheet feeder for supplying single sheets of paper to a printer's paper feeding mechanism. The sheet feeder is pivotably mounted so that the paper supply is maintained in contact with a fixed position feed roller. The feed roller is actuated when a sheet of paper is to be fed into the printing mechanism. The sheet feeder's pivot point is chosen to provide constant feed pressure to the paper supply regardless of the size of the remaining paper supply.
