1. An electronic thermometer comprising:

  • temperature sensing means for detecting the body temperature and developing a data signal representing the body temperature;

    memory means for storing a said data signal for each of at least five days;

    graphic display means for displaying body temperature variations in accordance with said data signals stored in said memory means;

    control means for interconnecting said temperature sensing means, said memory means and said graphic display means;

    measurement start key means in said control means said detecting operation of the body temperature through the use of said temperature sensing means;

    memory key means in said control means for instructing a memorizing operation of said data signal into said memory means;

    display key means in said control means for activating said graphic display means to display a temperature corresponding to said data signal;

    time period counting means in said control means responsive to actuation of said measurement start key means for counting a time period starting from such actuation;

    said control means disabling said temperature sensing means when the time period counted by said time period counting means reaches a predetermined value; and

    interruption means responsive to said memory key means and said time period counting means for disabling said temperature sensing means when said memory key means is actuated before said predetermined value is counted by said time period counting means;

    said memory means comprising;

    a first memory section for storing the data signal which represents the body temperature of the present day;

    a second memory section for storing the data signal which represents the body temperature of one day ago;

    a third memory section for storing the data signal which represents the body temperature of two days ago;

    a fourth memory section for storing the data signal which represents the body temperature of three days ago; and

    a fifth memory section for storing the data signal which represents the body temperature of four days ago.
