に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an electronic thermometer having a temperature measurement completion notification function. Furthermore, the present invention relates to an electronic thermometer that can display both degrees Celsius and Fahrenheit.
従来、検温終了報知機能を有する電子体温計は第２図の
ように構成さｎ′ｆｃものが知らｎている。Conventionally, an electronic thermometer having a function of notifying the end of temperature measurement is constructed as shown in FIG. 2.
第２図において、温度測定回路１で測定さｔた温肚を最
高値ラッチ２に保持さｔ′Ｌｆｃ以前までの最高値と比

値ラッチ２を曹きかえる。最高値ラッチ２には常に最高
値が保持さ扛表示４に表示する。In FIG. 2, the temperature measured by the temperature measurement circuit 1 is held in the highest value latch 2, and the comparison circuit 8 compares it with the highest value up to t'Lfc, and only when it is determined to be large or high. Reset the highest value latch 2. The highest value is always held in the highest value latch 2 and displayed on the display 4.
一方演算回路６は温度測定回路１で測定さ扛た温度の時
間的増分あるいは変化率を計算し、時間的増分あるいは
変化率が所定値以下になったときに、表示４に検温終了
であることを表示する。On the other hand, the arithmetic circuit 6 calculates the time increment or rate of change of the temperature measured by the temperature measurement circuit 1, and when the time increment or rate of change becomes less than a predetermined value, the display 4 indicates that the temperature measurement is complete. Display.
しか１．従来のように測定温度の時間的増分を演算して
検温終了を報知する電子体温計は、回路が複雑で大規模
なものになってしまうという欠点があった。Only 1. Conventional electronic thermometers that calculate the temporal increment of the measured temperature to notify the end of the temperature measurement have the disadvantage that the circuit is complex and large-scale.
さらには、セ氏表示、カ氏表示両用の電子体温計を提供
するためには、演算回路を２種類用いなけｎばならない
という欠点があった。Furthermore, in order to provide an electronic thermometer that can display both degrees Celsius and Fahrenheit, there is a drawback that two types of arithmetic circuits must be used.
そこでこの発明は従来のこのような欠点を解決するため
、非常に簡単な構成で検温終了を報知でき、またセ氏表
示、力比光示両用できる電子体温計を提供することを目
的としている。SUMMARY OF THE INVENTION In order to solve these conventional drawbacks, it is an object of the present invention to provide an electronic thermometer that can notify the end of temperature measurement with a very simple configuration, and can also display both Celsius and force ratio light.
上記問題点を解決するためにこの発明は、測定周期をカ
ウントし、最高値が測定さｔ′Ｌｆｃときにリセットさ

とし、非常に簡単な回路で検温終了報知機能付の電子体
温計を実現できるようにした。In order to solve the above-mentioned problems, the present invention has a configuration that notifies the end of temperature measurement using a temperature measurement end counter that counts measurement cycles and is reset when the highest value is measured t'Lfc, and has a very simple circuit. We have made it possible to create an electronic thermometer with a function to notify the end of temperature measurement.
また、検温終了カウンタがカウントする所定数を、カ氏
表示の場合はセ氏表示の半分とするように構成し、セ氏
表示、カ氏表示両用の電子体温計を実現できるようにし
た。In addition, the predetermined number counted by the temperature measurement end counter is configured to be half of the number counted in Fahrenheit and Celsius, thereby realizing an electronic thermometer capable of displaying both Fahrenheit and Fahrenheit.
上記のように構成さｔた電子体温計の検温終了カウンタ
は、測定周期をカウントする一方測定値が以前までの最
高値より大きい場合リセットされる。すなわち、温度上
昇中は常にリセットさ扛、温度上昇が飽和したとき、つ
まり最高値が所定時間更新さｎなかったとき、検温終了
であることを報知する。この所定時間の計数は、検温終
了カウンタで測定周期を所定数カウントすることにより
実現できる。The temperature measurement end counter of the electronic thermometer configured as described above counts the measurement period and is reset if the measured value is greater than the previous maximum value. That is, it is always reset while the temperature is rising, and when the temperature rise is saturated, that is, when the highest value has not been updated for a predetermined period of time, it is notified that the temperature measurement is finished. This predetermined time count can be realized by counting a predetermined number of measurement cycles with a temperature measurement end counter.
また、カ氏温度をＦ、セ氏温度′ｆ：Ｃとするとそ、セ
氏表示の１．８倍の変化率になる。そこでカ氏表示の場
合は、検温終了カウンタがカウントする所定数をセ氏表
示の半分にすることにより、簡単な回路でセ氏表示、カ
氏表示両用にできる。Further, if the temperature in degrees Fahrenheit is F and the temperature in degrees Celsius is 'f:C, then the rate of change is 1.8 times the rate of change in degrees Celsius. Therefore, in the case of Fahrenheit display, by setting the predetermined number counted by the temperature measurement end counter to half of the Celsius display, a simple circuit can be used for both Celsius and Fahrenheit display.

値が保持さｎ表示４に表示する。In FIG. 1, the temperature measured by the temperature measuring circuit 1 is held in the highest value latch 2 and compared with the highest value up to 1rLfc in the comparison circuit 8, and only when it is judged to be larger, the highest value latch 2 Rewrite. The highest value is always held in the highest value latch 2 and displayed on the n display 4.

ても、検温終了報知機能を損うものではない。On the other hand, the temperature measurement end counter 5 counts the pulses 10 that are generated every time the measurement is synchronized. The temperature measurement completion counter 5 is composed of flip-flops 11, 12, '13, 14, and 15, and when the Q output of the flip-flop 15 reaches 16H level, the display 4 indicates that the temperature measurement has been completed. Furthermore, the temperature measurement end counter 5 is activated when the maximum value is measured, that is, when the temperature measured by the temperature measurement circuit 1 is determined to be larger than the value held in the maximum value latch 2. , comparison - is reset by the output signal of the circuit 8. - In this example, after counting the measurement period 10 16 times, the Q output 16 of the flip-flop 15 becomes "
■For example, set the measurement period to 1 second,
If the resolution of the measured temperature is 0.1°C, the temperature measurement completion will be notified when the temporal increment of temperature becomes 0°l''°C/16 seconds or less. It is for selecting the display and F temperature display. When the Celsius and Fahrenheit selection signals 21 are at the 1H5 level, it is Fahrenheit, and when it is at the "L" level, it is Fahrenheit. In the case of Fahrenheit display, the temperature measurement is completed by bypassing the flop 11 with a frit. The count number of the counter 5 is half of that when the temperature is displayed in degrees Celsius.As mentioned above, the rate of change in the temperature in degrees Celsius is 1.8 times the temperature in degrees Celsius, but it is assumed that it is about twice as much as the temperature measurement end force □ Counter 5 Even if the number is half of that displayed in degrees Celsius, the temperature measurement completion notification function will not be impaired.
