  • Plotter having a support platen of angular profile
    Patent number: 4916466
    Abstract: A paper sheet (10) is supported by a platen (30) having a horizontal central portion (31, 41, 51) including the write path and having front and rear portions (40, 50) for supporting the sheet in front of and behind the central portion. Each of the front and rear portions comprises a plurality of plane faces (42, 43, 44; 52, 53, 54) interconnected by horizontal edges (46, 57; 56, 57) and forming increased angles (a, b), relative to the horizontal. The selected shape of the edges and the faces is such that when the sheet (10) is resting against the second and third edges (46, 47, 56, 57) it is constrained to keep off the first and second faces (42, 43, 52, 53) and to lift above the level of the central portion (31) prior to coming into contact therewith.
