Abstract
A paper feed roller arrangement for a printer which permits exchanging of a ribbon cassette and assures a maximum range of paper on which printing can be made. The paper feed roller arrangement includes two pairs of paper feed rollers, one disposed on the upstream side and one disposed the downstream side of a print head in a feeding direction of paper for feeding the paper in a planar condition. One of the paper feed rollers which is opposed to a path of the ribbon cassette when the ribbon cassette is to be exchanged is disposed for movement toward and away from the print head. Upon ordinary feeding of paper, the movable paper feed roller is positioned proximate the print head where it cooperates with a corresponding paper feed roller to feed the paper. When a ribbon cassette is to be exchanged, the movable paper feed roller is moved away from the print head to increase the spacing in the vicinity of the print head to facilitate such exchanging of the ribbon cassette.
