Abstract

An electronic thermometer suited for measuring a basal body temperature comprises a current time information keeping circuit. A time preset system is included in the electronic thermometer so that a desired time at which the body temperature measuring operation should be performed is preset in the electronic thermometer. When the current time reaches the preset time, the body temperature measuring operation is automatically conducted, and the measured data is stored in a memory means. A digital display unit is associated with the memory means so that the measured body temperature stored in the memory means is displayed on the digital display unit at any time.

Claims

1. An electronic thermometer comprising:

temperature measuring means for measuring a body temperature,

said temperature measuring means comprising a temperature sensor probe, an oscillator circuit of which the oscillation frequency is a function of the output signal derived from said temperature sensor probe and counter means for counting said oscillation frequency of said oscillator circuit which is a measure of said body temperature;

time information keeping means for storing current time information;

preset time memory means for storing a preselected time data at which the body temperature measuring operation is to be performed;

coincide detection means for developing a coincide detection output when the current time information stored in said time information keeping means becomes identical with said preselected time data stored in said preset time memory means;

drive means for activating said temperature measuring means when said coincide detection output is developed from said coincide detection means;

temperature memory means for storing a measured temperature derived from said temperature measuring means in response to said coincide detection output derived from said coincide detection means; and

a temperature display unit for displaying said measured temperature stored in said temperature memory means,

said temperature memory means comprising a latch circuit for storing the count information relayed from said counter means, said count information representing a function of the body temperature for display on said body temperature display unit, whereby the temperature measuring means performs the body temperature measuring operation via said temperature sensor probe automatically in response to said output signal derived from said temperature sensor when said coincide detection output signal is received from said coincide detection means, the body temperature data obtained in said temperature measuring means being applied to and stored in said temperature memory means for display on said temperature display unit.

2. The electronic thermometer of claim 1, wherein said drive means comprises a one-shot multivibrator for activating said oscillator circuit for a predetermined period of time after generation of said coincide detection output derived from said coincide detection means.

3. The electronic thermometer of claim 1, wherein said current time information display unit, said preset time information display unit and said body temperature display unit are included in a liquid crystal display panel.
