- 1 - Abstract: The invention provides a paper loading system for use in a printer having a platen and a paper bail mounted with two rollers. A carriage having a projection is provided to move parallely to the platen. At the free end of the projection, a photodetector is provided to detect an edge of a loaded paper so as to memorize the opposite ends of the loaded paper. When the paper bail is in a pressing position at which rollers are holding the paper on a path of advance of the paper, no engagement is accomplished between the projection and the rollers. But when the paper bail is in a releasing position at which rollers are separated from the path to release the paper, the projection may come into contact with rollers to change the position of rollers. Using the memorized data, the movements of the carriage and the paper bail are con- trolled to locate the rollers at the opposite side rims of the loaded paper.
