ABSTRACT:
A recording apparatus is provided which is capable of transferring recording information from an ink film to recording paper without clogging the recording paper in the recording apparatus. The recording apparatus includes a thermal recording head which generates heat in response to recording information to transfer ink from an ink film to the recording paper thereby printing the recording information on the recording paper. An ink film guide roller guides the ink film from the thermal recording head without forming wrinkles in the ink film. A separating plate is positioned closely adjacent the ink film guide roller to separate the recording paper from the ink film. The ink film guide roller has a pair of side rollers and a center roller, the diameters of the side rollers being greater than the diameter of the center roller in order to reduce the formation of wrinkles in the ink film. Most importantly, the separating plate includes a separating edge having a central portion adjacentg the center roller and two side portions adjacent the side rollers, the central and side portions of the separating plate being dimensioned to provide substantially the same gap between the center roller and the central portion of the separating plate as between the side rollers and the side portions of the separating plate. Thus, the entire edge of the separating plate can be positioned close to the ink film guide roller to establish a constant narrow gap between the separating edge and the ink film guide roller.
