Summary:The utility model relates to a heat-key-mode text-data processing apparatus capable of supporting multi-key processing. Input key sets are arranged in single line (column) along the edge of a display; the functional meanings of the keys are corresponding to the contents displayed by the display. A microprocessor is connected with the display through an I/O expanding unit; a matrix of the input key set provides encoding keys and interrupt signals to an I/O port and an interrupt port of the microprocessor. Due to the adoption of the heat-key operating mode, the utility model simplifies a traditional key processing mode, realizes finishing the two functions of selecting and acknowledging by one key, and has the advantages of convenient and simple operation, high work efficiency, high key response speed, timely response and high real-time performance.
