In a thermal printer having a flat platen, a flat platen support mechanism comprises a flat platen support plate, and a frame body. A projection having a curvature is provided between the flat platen support plate and the frame body. The projection having a curvature is to be swingable freely and to be movable with a slip movement. The projection is arranged on a center line of a flat platen width. When a thermal head is pressed with the flat platen, the flat platen swings smoothly. The thermal head is face contacted uniformly with the flat platen.
