Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermometer and an electronic temperature measuring device for monitoring and maintaining equipment.

[Conventional technology]

This Kusunoki electronic temperature measuring device has been adopted in many parcels in recent years, and is rapidly becoming popular for garden use, replacing the conventional mercury meter, due to its ease of use. . This is done by distributing the sensor and T6tz I & to the object to be constructed, processing the output signal of the sensor with a display circuit, and displaying the obtained axis results on the display screen. The outer leather circuit is activated at the same time as operation is started by operating a switch. Body temperature reading 1
In this case, the ladder-shaped main body case has front/r and b switches, and a sensor is housed at the tip.

[4 points while the invention is about to come to an end] By the way, such a temperature measuring device, for example, if it is a hygrometer, it will take 9 pieces to measure one body temperature, and it will be placed under the armpit or under the tongue and put in the mouth. Therefore, even though a display screen is provided, it is not clear whether the displayed temperature value is changing or not.

Therefore, if you use a conventional mercury thermometer to measure the temperature of a sea urchin for, say, 5 minutes, the temperature value will no longer change, and the displayed temperature value can be considered to accurately represent the body temperature, but it will measure for 1 hour. In addition to the time-consuming process, actually measuring the temperature of 5 molecules ij resulted in a positive @1. The VC body temperature is displayed at a constant rate, and depending on the usage, the 5 minute period may seem very long, and the temperature measurement will be completed and displayed in a shorter period of time than the 5 minute song. In some cases, you may end up looking at the temperature value.

There is a problem with the temperature value displayed as 1 like this.

Furthermore, when the & stock malfunctions, it may be necessary to detect abnormal temperatures while observing the phenomenon of the malfunction. In such a case,
If the location where the failure phenomenon is observed is far from the location where the temperature display screen is installed, this will cause problems in cropping. Also, temporary abnormal temperatures occur. For ice machines, it is necessary to constantly monitor the display screen in order to quickly find out about sudden failures.

[Means for solving problems]

This invention was made in view of the above circumstances, and is designed to classify temperatures or "constant dry ranges" and provide different notifications for each predetermined range using sound, light, etc. This notification allows you to easily and intuitively determine the position even at a position that has been removed from the measuring device or a position where the display screen cannot be formed. Since ￥V knowledge does not change, measurement 1
The purpose of this method was to increase the reliability of the measured value by making it easy to know that the value represents the body temperature that is being measured.

Temperature measurement part 11. Display decoder 14. Falling edge detection section 1
9. Level edition meeting 24. When the signal supplied to the reset terminal is still at level (hereinafter referred to as ")i"), the rising edge output device 25 and the notification signal generator 26 respectively
It is in a reset state.

The switch 1 is a normally open switch that can be operated from the outside, such as a bush switch, a slide switch, or a reed switch provided inside the main body case (not shown) that is operated from the outside using a magnet. It is connected in series with a resistor between the voltage terminal and the ground terminal to which positive voltage VDD is applied. The connection point between this resistor and switch 1 is the counter 4- and the ratte circuit 5.
Reset terminal and Nantes gate AK f&
Mt and when switch 1 is not operated (ie, in the open state), a signal of 1lH1+ is supplied to these.

Oscillator 2 is C1 (oscillator, crystal oscillator, etc., and generates reference clock MCK. This reference clock MCK
is divided by the required frequency π by counter 3, and then divided by counter 5,
9 and display decoder 14 as a clock. Further, the count value of the counter 3 is
It is offered to

The oscillator 2 and the counter 3 can be switched between the operating state (re-nut release state) and the non-operating state (reset state) by the MCK ON signal obtained by inverting the output of the Nant gate 4 with the inverter 4-8. .

The counter 5 and the latch circuit 6 constitute a determining section for determining whether the switch 1 has been operated (that is, whether it has entered the closed state). This counter 5 counts the clock from the counter 3 when the switch 1 is operated to release the °C reset. When the counter 5 first counts 1, its Q output is inverted from +2 ``L'' (low level) to 1H'', and thereafter, every time the counter 5 counts 1-1, its Q output is inverted.

On the other hand, the latch circuit 6 is set at the rising edge of the Q output of the counter 5 after the reset is released, and the Q output is 1H.
“L”K unless reversed and reset from “L” to “L”
Retained.

The counter 5 and the latch circuit 6 are in a reset state when the switch 1 is closed, and are in a reset release state when the switch 1 is closed, and each time the switch 1 is operated and becomes the closed state,
The Q output of the latch circuit 6 is inverted from "H" to "Ll". Therefore, this Q output changes from "H" to "L".
This inversion indicates that switch l has been operated.

The counter 7 is a 1-bit binary counter that counts by one at the falling edge of the Q output of the latte circuit 6, and the Q output is inverted every time it counts. Q of counter 7
The output is inverted by the inverter 20 and becomes G l(S 'f'
1 (No. 0 is formed, and this GLE ST1 signal is sent to the counter 91 display decoder 1 along with the previous Nant gate 4.
4. It is also supplied to the reset terminals of latch circuits 17 and 18.

Counter 9 further divides the clock from counter 3. The Qj ratio of a predetermined frequency division ratio is supplied to the output control area 10, and the side temperature? At flS11? Controls the timing of 1111 lines. Q! The QIr+ output of the frequency division ratio of the small output 2 is fed to the latch circuit 17 as a set input, and the Qrn output 2
The Qn output with the double frequency division ratio is supplied as the latch circuit 18vC set input. The latch circuit 17 is set at the first rising edge of the Q-output of the counter 9 after the reset is released, and the Q-output t'! It is held until it is reversed from "H" to ILI and reset. The Q output of this latch circuit 17 is a control +tA1 signal as a Ga5T2 signal.
0. It is supplied to the reset terminals of the temperature measurement section 11 and the falling edge detection section 19, and the inverter 21
It is inverted by the inverter 23 and supplied to the NAND game) 16, and further inverted by the inverter 23 and supplied to the measurement range +2fi outside detection section
It is also supplied to the EN terminal of. Further, the latch circuit 18 is
The reset release signal is set on the first rising edge of the Q-output of counter 9, and its Q output &)"f(" to II
LI t,c will remain until it is reversed and reset.
It will be decoded. This Q output is immediately supplied to the falling edge detection section 19 which has been released from reset, and when the falling edge is detected, a ratio signal is formed.

The memory unit 12, which is a MAX-type flip-flop, is reset. The Q output of the ratte circuit 18 is also supplied to the Nant gate 16.

The temperature measuring section 11 starts operating when the reset is released, and measures the temperature once every cycle of the QI output of the counter 9, that is, the temperature is measured. Each temperature measurement is completed immediately before the rising edge of the Qz ratio output of the counter 9. The temperature measuring section 11 is
In synchronization with the rising edge of this Q1 output, the m111 temperature value obtained by each temperature measurement (hereinafter referred to as the current temperature measurement value) is compared with the temperature measurement value held in the storage unit 12, and the current measurement value is calculated. When the temperature value is large, a MAX·φ signal is generated and the current measured temperature value is written in the storage unit 12 in place of the previously held temperature value. Therefore, the temperature measurement unit 1 is stored in the storage unit 12.
Among the current temperature values obtained so far after the reset of 1 is released, the largest one is held.

The storage unit 12 retains data even after the power is turned off. Therefore, even after the vA section 11 stops operating, the storage section 12 retains the maximum current temperature value obtained during the 70-year sea bream until it is reset by the MAX/ratio signal.

The side temperature value held in the storage unit 12 is extracted, supplied to the display decoder 14 via the measurement range detection unit 13, and displayed on the display 15. If the temperature value is outside the specified measurement range, the display 15
In order to display that fact, the out-of-measurement range detection unit 13
Instead of the side temperature value, data representing measured values, symbols, patterns, etc. is output to the display decoder 14.

Here, the above predetermined measurement range is 35.0'C~42,
The temperature shall be 0°C. The temperature value held in the first test section 12 before being reset by the MAX-R signal before the temperature measurement section 11 starts operating (this is the measurement result of the previous measurement, hereinafter referred to as the previous temperature measurement) ), this is 35.
When the temperature is below 0°C, the out-of-measurement range detection section 13 detects r
35.0°C, and when it exceeds 42.0°C, it is displayed as 42.0°C. In addition, when displaying the current temperature weir held in the storage unit 12 after being reset by the MAX-C signal, if it is less than 35.0°C, it is displayed as "LO℃J, exceeding 42.0°C". Sometimes [H
Symbols and patterns such as I'CJ are displayed on the display.

In this way, the previous temperature measurement value outside the predetermined measurement range and the machine $11
T! In order to display the ih value differently, the out-of-defined-range detection section 13 is controlled by a signal obtained by inverting the GR8T2 signal using an inverter 23. Cy)
t, 8'r 2 signal is the display period of the previous side temperature value,

It is.

The display decoder 14 and the display 15 constitute a display surface. For this reason, the display decoder 14 does not send any signal to the display 15 when reset.

The display 15 is in a blank display state with no display. (J B S '1" 1 When the reset signal becomes 1L" and the reset is released, the display decoder 14 inverts the output of the Nant gate 16 with the inverter 22 and outputs Di.
As long as the sPR signal is ILI, the outside of the defined range detection section 13
The output of the multiplexer 13 is decoded and the above display is performed in the display w 15. However, when the IJisPR signal becomes 1H'', it is preset and stops receiving the output of the multiplexer 13, and the display Ks 15 displays all the segments. Provides a signal to turn on the light.

The level discriminator 24 and the rising edge detector 25 count the level discriminators. The level discriminator 24 is preset with temperature ranges (hereinafter referred to as ranges), and when the output of the supination detector 13 (g) is supplied to the The determination unit 24 determines which range this falls into, and outputs a signal corresponding to any one of Q and Q4 of C"H".

FIG. 2 shows an example of each range set in the level discriminator 24. In this example, temperature T of 35°C or higher is determined as 35°C≦T<36°C, 36°C≦T< 37°C23
It is divided into four ranges: 7℃≦T≦38℃, and 38℃≦T. Then, the level discriminator 24 outputs one of the signals Q1 to Q4 as follows, depending on the range in which the m degree T represented by the output signal of the out-of-defined-range detection section 13 falls.

When 35℃≦T 36℃, Q4 signal 36℃≦T〈37℃, Q, signal 37℃≦T When 38℃, Q8 signal When 38℃≦T Q4 signal In the following explanation , the level discriminator 24 is assumed to have its range set in this way and output signals Q1 to Q4.
The range of each range is not limited to this, and any VC can be set.

The rising edge detector 25 detects the rising edge of each No. 91 to 9416 from the "Repe" size B'us 24,
A constant width of Q1' to Q4' that rises at this rising edge
Output a signal. That is, the rising edge detector 25 receives the QI multiplied signal from the level discriminator 24;
When 3t4) is supplied, it outputs a constant duck Q, / signal that rises at the rising edge of 7.

The notification signal generating section 26 is a decoder, and although the counter values are sequentially supplied from the counter 3, it selects the counter value according to the Q1/~Q4' signal supplied 1L from the rising edge detector 25, The notification signal DI (is generated only during the periods Ql' to Q4'. This notification signal DR is Q,
/~Q4' signals so that they are the same as each other.

Therefore, although the notification signal range differs depending on the range set by the level discriminator 24, an example thereof is shown in Figure 2. In this example, the notification signal is composed of pulses of a predetermined repetition frequency generated every required period.The repetition frequency a becomes higher and the number of pulses increases as the temperature range increases.

In order to form such a notification signal, K is a notification signal generating section 2.
In step 6, numerical values corresponding to each of the Ql' to Q, / signals are set, and the number of numerical values set for the Q,' signals is small (and the tic
L, Qt'*, Qs' * Q+' (1111 K of the fi number. Increase the number of numerical values to be set so that the difference between them becomes small. Then, if any of the Qt' to Q4' signals is supplied Then, select the above-mentioned numerical values corresponding to that signal, compare these numerical values with the count value from the counter 3, and generate a pulse when the two match. The signal generator 26 generates a number of pulses equal to the number of numerical values VC selected by one of the signals Q and / to Q4' once every counting cycle from the minimum count value to the maximum count value of the counter 3. This is the notification signal DH.

It is. In the following explanation of the operation, this counting operation cycle of the counter 3 is set to a period from when the Q7 output of the counter 9 is inverted until the next inversion.

In this case, it goes without saying that the period of the clock output from the counter 3 is sufficiently shorter than the above-mentioned counting operation period of the counter 3, and for this purpose, for example,
2 of a number of divide-by-2 dividers counting counter 3
The clock may be generated from the output of the frequency divider.

In addition, as described above, instead of making the notification signal DR a pulse signal with a repetition frequency that differs depending on the QB' to Qa' signals, the width may be constant or the repetition frequency may be changed depending on the Ql' to Q4' signals. Pulses with different levels may be used.

The notification signal IJ generated by the notification signal generator 26 is supplied to the notification s27.

The notifying unit 27 has an annunciator 29 and a transistor 28 connected in direct contact between a power terminal to which a positive power supply voltage VDD is applied and a ground terminal. is supplied and the alarm 29 is activated. The alarm 29 is a puller.

A lamp, a light emitting element, etc. can be used.

Next, the operation of this embodiment will be explained using FIGS. 3 and 4 showing the operation timing of each part. To avoid complication, first, the parts other than those related to notification will be explained using FIG. 3, and then the parts related to notification will be explained using FIG.

In Fig. 1 and Fig. 3, when not in use, the previous temperature measurement value Nx' is retained in the storage unit 12, regardless of whether the air conditioner (not shown) is turned on or off. When the power is turned on, the display screen 15 is activated, but if a battery is used as a power source, '#It' is normally turned on and the display tm15 is turned on even when not in use.
is in one set of actuation states.

At this time, counter 7 has been reset and divided by m, but its Q output &'! “L” and q-STI signal is @H
It is I. Further, the switch 1 is in the closed state (Kdr), and the counter 5 and the latch circuit 6 are in the reset state.

Therefore, since both of the two inputs of the Nant gate 4 are K ``I('', the MCK ON signal is H'', and the oscillator 2.
Counter 3 is in a reset state. Also.

Since the QR8TI signal is H'', the counter 9° display decoder 14 and latch circuits 17 and 18 are also in the reset state, and the display 15 displays blank.

Furthermore, since the 1latte circuit 17 has been reset, its Q output is H", and for this reason, G HIS
T2 m kt "H" tear)te, control R1
510, temperature measuring section 11. Falling edge detection section 19. Level discriminator 24. The rising edge detection section 25 and the notification signal generation section 26 are also in a reset state. *H++ GR8T2
The signal is inverted by the inverter 21 and supplied to the Nant gate 16, and is further inverted by the latch circuit 18 in the reset state.
Since the 1Hw Q output of is also supplied to the Nandts gate 16, the L)isPR signal obtained by inverting the output of this Nandts gate 16 by the inverter 22 is ILI.

The above is the state of each part when not in use.

In this state, when switch 1 is operated to close, the input of switch 1 of Nantes gate 4 becomes "L".
Therefore, the MCK-ONii signal becomes "L" and the oscillator 2. Counter 3 is reset. For this,
The oscillator 2 generates a reference clock IVCK, which is frequency-divided by the counter 3.

At the same time, the counter 5 and the latch circuit 6 are also reset, and the counter 5 counts the clock from the counter 3. When the counter 5 counts, its Q output is inverted from IL'l to "l-1", and the latch circuit 6 is set at the rising edge.

For this reason, the Q output of the ratte circuit 6 changes from 1H'' to ILW.
The counter 7 counts by 1 at the falling edge. By this count, the Q output signal of the counter 7 is inverted, and the G 1 (18'r 1 signal is inverted from IHII to IILIIK. Along with this, the counter 91 display decoder 14.
8 is reset. As a result, counter 9 starts counting the clocks from counter 3. Further, the previous temperature measurement value Nx' read out from the storage section 12 is sent to the display decoder 14 via the out-of-measurement-range detection section 13, where it is decoded and displayed as rT-"Cl on the display 15. .In this case, if the previous temperature measurement value Nx' is outside the ultra-short measurement axis opening, it will be "35.0℃" or r42
．． Needless to say, "0℃" is displayed.

In such a state +x, even if the switch 1 is in the open state after the operation is completed, there is a slight problem. This is because when the switch 1 is opened, the counter 5 and the latch circuit 6 are reset, and the Q output of the latch circuit 6 is inverted from "L" to "H", but the counter 7 is not affected by this. Therefore, the G STI signal is kept as it is, and therefore the M(,'K·ON signal obtained from the inverter 8 is kept as it is).

When the counter 9 continues counting and counts a predetermined number l, *HWK is inverted from s Q' small output ILI, and when it further counts by l and the count 1 reaches 21,
In addition to reversing the Qz ratio output from "H" to "L", the Qm
The output power is inverted from L1 to 7H''. The latch circuit 17 is set by the rising edge of this Qr11 output, and its Q output, that is, the GLE ST2 f= signal is mHII
From “L” K is inverted.

Therefore, the reset of the control unit 10 and the ouj1bn' unit 11 is canceled, and the PJN of the out-of-measurement-range detection 1b13 is released.
The signal supplied to the terminal is inverted from IILI+ to "H", and the display of the temperature value outside the range for (2) is typically set to 5. Furthermore, the input on the inverter 21 side of the Nant gate 16 becomes 1H'', and the input of the other latch circuit IB[li is also IIH1', so the DisP signal is inverted from "L" to H"K, and the display decoder 14 is preset. As a result, the 1-display decoder 14 is prohibited from accepting data from the out-of-measurement-range detector, and all segments of the display 15 are lit.

In this manner, by lighting all segments of the display 15, the operation of the display decoder 14 and the display 15 in the royal palace can be suppressed before the temperature measurement starts.

Counter 9 continues to count and KARANTOI vLQ

) to "L", and the Q11 output is inverted from "Ll" to "W." Due to the rise of this '=9-output, the output of the latte circuit 18
The Q output of is inverted from "H" to "L". This falling edge of the Q output is detected by the falling edge detection section 19, and the M

2 is reset. This Akakichiku, in Ki 1 Onbu 12,
The previous gilaN3/ is erased and the value 0 is held.

In addition, since the Q output of the latch circuit 18 becomes 1L'', the output of the Nant gate 16 also becomes H'', and therefore the DisP signal becomes 1L'' and the display decoder 14
The preset will be canceled. As a result, display decoder 1
4&1. The temperature value read from the recording section 12 is supplied via the out-of-measurement-range detection section 13, but in this case, this side Yjt i1u is 0 and is out of the measurement range, that is,
Since the temperature is 35.0℃, there are 11 fixed axes, 1 outside detection area, and 1

41C is supplied, so that this is displayed on the display 15.

When the count value of the counter 9 reaches 51, the Qt output is inverted from L'' to H'', and the control section 10 detects this inversion and sends a signal to the temperature measuring section 11.

On the other hand, in the mll temperature section 11, the first (II) temperature has been completed just before the above-mentioned Qt small output rising edge of the counter 9, and when the control section 10 also receives the signal, it reads out the measured temperature value from the storage section 12. The current temperature measurement value N is softer than the current temperature measurement value N. In this case, since Mj'f, the measured temperature value f directly is O, the current temperature measurement value N is larger, and therefore, the temperature measurement part 11 is 1
vl A Sends the X・φ signal to the storage unit 12 and stores the current temperature value N
, write down! , and store it in section 12. As a result,.

The display 15 shows the displayed value [1゛] for the measured temperature value N, vc.

℃" will be displayed.

Note that the period during which the counter 9 counts by l is set here to approximately 0.7 seconds.

Qt small output has a cycle of about 1.4 seconds, 9m output has a cycle of about 2.8 seconds, and Qn output has a cycle of about 5.6 seconds. Therefore, it takes about 1.4 seconds to display the previous temperature value T, / and the period "1° for all segment points on the display 15", and the previous "LO℃"
is displayed for approximately 0.7 seconds.

Further, the counter 9 continues to count, and when the count value reaches 6, the Ql small output is reversed from H" to "L", and then when the count value reaches 71, the % Q' output + x" changes from "L" to "
The temperature is reversed to "H". Along with this, in the temperature measuring section 11,
The current temperature value N obtained immediately before that and the temperature measurement value N1 held in the storage unit 12 are compared, and when the current temperature measurement value N is large, the current temperature value N is Temperature value N, VC can be omitted. Therefore, on the display 15, this temperature measurement value N! 1st line r'rt'c' is displayed.

In this way, unless the switch l is operated, the counter 9 continues counting, and the current temperature value and the memory unit 12
The temperature value held in is stopped and the current temperature value is 4t (x
When the number of million is large, a pill; = ”currently received at J12]
Temperature value [=〆f can be measured. Therefore, the display 15 displays the maximum fA value measured by 1) 1111 and 111. As "C" increases, the value displayed is updated.

In addition, the 9m output of the counter 9 is as follows every 47 counts.
Further, the Qn output rises to 81 counts, but the latch circuits 17 and 18 are kept in the set state, and the above-mentioned side temperature operation continues.

Next, switch 1? : When closed, the counter 5 and latch circuit 6 are reset. In this case too, MCK・ON
Since the signal is held at ILI+, oscillator 2 and counter 3 are active. Therefore, counter 5 is counter 3
When the clocks from the latch p=! are counted and the output of K. I kfr 6 kl is set and the Q output vx is inverted from "H" to "L". As a result, the Q output cover of the counter 7 is inverted and the Ga5T1 signal +x is inverted from "L" to "H". Therefore, the display decoder 14 is reset and the display 15 displays a blank.

At the same time, counter 9. The latch circuits 17 and 18 enter the reset state jz14, and as a result, the Q outputs of the latch circuits 17 and 18 are reversed from L'' to 19. Level issue divider 24. Rising edge calculator 25 and notification signal generator m26 are also reset. In this case, since the MAX-ratio signal is not dead or alive, the storage unit 12 stores the maximum number up to now. 1 temperature value N, is maintained as it is.The stiff temperature measuring part N, becomes the previous side temperature value at the time of the next temperature measurement.

Furthermore, one input of the Nantes gate 4 (j

1LN, and the MCK ON signal is 1L".
The human power is both K”l-1”, therefore, MCK・
The σN signal becomes lHl, and the oscillator 2 and counter 3 become inactive. Of course, counter 5 and latch circuit 6
is also in the reset state.

In this way, each circuit becomes inactive, and the entire device stops operating.

Next, using FIGS. 4(a) and 4(b), the portion related to notification in FIG. 1 will be explained.

As explained earlier, the temperature measurement unit 11 started operating due to busy schedule.

These temperature values written in the storage unit 12 are supplied to the display decoder 14 via the measurement range out-of-range detection unit 13, and are decoded and displayed on the display 15 as a display value r for these temperature values.
'r'1℃" = rT! 'Cl = "" = rTt
o'cJ = rTtt°CJ = .

The level discriminator 24 discriminates which of the above ranges the supplied temperature value falls into, but when the side temperature values N, , N, are supplied, the temperatures T, , T, for these are determined.
Since the temperature is less than 35° C., the level discriminator 24 does not generate any output.

Next, when the temperature value N3 is supplied to the level discriminator 24,
The temperature T corresponding to this is 35° C.≦T (36° C.), so the level discriminator 24 outputs Q11 of 1H1.

Therefore, the rising edge detecting section 25 detects the rising edge of this Q signal, and the counter 9 counts 21 times, which is equal to the constant width of the rising edge (in this case, the temperature measuring period T of the side temperature section 11). outputs a Q,/ signal of equal to the period).

This Qt' signal is supplied to the notification signal generator 26.

The notification signal generator 26 decodes this Qt' signal, and outputs the notification signal DI (, which is made up of 21 pulses with the lowest repetition frequency) twice during the period of this Q1/signal (as explained earlier). (The period of occurrence of the notification logic number DR is equal to the period counted by the counter 9).

This notification signal is supplied to notification $27, and notification signal 1
1) The alarm 29 emits a sound every time there is a pulse. in this case,
The notification signal D consists of two pulses IJ.

Since this is generated twice, the generation f from the alarm 29 becomes beep, beep, beep. - When the temperature value N is supplied to the level discriminator 24, the level discriminator 24 outputs a Q signal of 1H'', and the rising edge detector 25 outputs a constant Q signal that rises at the rising edge of the signal. A Q!' signal of width TI is output.Therefore,
During this period of Qt', the notification signal generating section 26 generates a notification signal DR consisting of three pulses having the next lowest repetition frequency. Therefore, the alarm 29 beeps,
A beeping sound is generated.

The measured temperature value Ns is input to the level discriminator 24 by setting the interval to +γ.

N. is supplied, the level discriminator 24 outputs a false signal sQ4 times, and along with this, the rising edge detector 25 outputs Qa'11 and Q4' respectively.
Nos. 1 and 7 are output. Therefore, the notification signal generator 26
In general, both the Qs' signal and the Q4' signal have a higher repetition frequency and a larger number of pulses, so that the Qs and Q4 signals are generated from the annunciator 29.
A sound corresponding to K is generated.

As described above, as the value displayed on the display 15 increases, the sound generated from the alarm 29 changes, and the temperature can be sensed from the sound generated even if the displayed value is not monitored.

In the above example, four ranges were provided (five ranges including temperatures below 35°C), but the valley range was made narrower (and #III was also used for temperatures above 38°C). By providing a narrow width range and greatly increasing the number of ranges, it is possible to know the measured temperature more accurately from the generated sound.Also, since the generated sound is no longer generated, the temperature measurement value has increased significantly. For example, when measuring VcvA of body temperature, etc., the reliability of the displayed value on the display 15 is improved.The above numerical values are only shown as an example for the purpose of explanation. The invention is not limited to these values.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to know the measurement results intuitively without monitoring the measurement results displayed on the display surface, and to perform highly reliable measurements from the display surface. It is possible to obtain results, and it is possible to obtain sophisticated effects not found in the above-mentioned conventional techniques.
