Abstract
A thermal recording apparatus for example for use in a facsimile machine includes a thermal printhead provided with a plurality of heat-producing elements arranged in the form of a single array and a platen roller which is pressed against the thermal printhead to keep a sheet of recording paper pressed against the array of heat-producing elements so that a heat pattern defined by the array of heat-producing elements is transferred to the sheet of recording paper efficiently. The platen roller is provided to be movable between a recording position where the platen roller is located separated away from the heat-producing elements so as to allow the sheet of recording paper to be separated away from the heat-producing elements and a stand-by position where the platen roller is located and adjacent to the heat-producing elements to keep the sheet of recording paper pressed against the heat-producing elements. The positioning of the platen roller between the stand-by and recording positions is automatically controlling depending on the mode of operation of the apparatus.
