Abstract
Abstract A recording apparatus includes a stationary suction member having a number of openings disposed opposite to recording device. Through the openings a suction force is applied to a recording paper to keep the paper in close contact with the stationary suction member for flat registration. Thereby, the flatness of the recording paper at the recording station is attained and the distance between recording means and recording paper is maintained constant.
