Abstract
A printer includes a platen roller and a print head for printing information on a recording medium moving between the platen roller and the head in a predetermined direction. The platen roller is supported by a supporting frame which is rotatably mounted on a supporting shaft so that the platen roller is rockable in directions to touch and leave the head. The platen roller is pressed against the head by an urging member. The platen roller is shifted in a direction in parallel to the moving direction by a shifting mechanism as the roller rocks, so that the position of the roller relative to the head is kept constant with respect to the moving direction of the recording medium.
