Abstract
A printer having a frame, a printing head and a platen, either one of the head and the platen is fixedly secured to the frame while the other is movably mounted on the frame by movable supports so that they are moved relatively toward and away from each other for the printing operation of a paper held therebetween when abutted against each other. The movable supports comprises a pair of supporting members each movably mounting other of the head and the platen independently from each other. Each of the supporting member is biased by a spring so as to urge the other of the head and the platen against the one of the head and the platen independently from each other. Thus, the parallel relationship between the head and the platen when abutted against each other for the printing operation is insured.
