Next, the operation of the electronic wristwatch configured as described above will be explained. First, for example, when the assembly of the watch module is completed, the switch S1 is operated depending on the material of the watch beak. That is, when the switch Sm1lfr is operated, the one-shot circuit 27 outputs a pulse signal 1 every time the switch 8a is operated, and the pulse signal 1 is inputted to the ternary counter 50 of the temperature correction U path 17. Therefore, the ternary counter 50 is incremented each time the switch Sa is operated. In this case, if the watch case is a metal case, 3
The contents of the advance counter 5.theta. are set to "O", "1" if it is a plastic case, and "2" if it is an insert case. When the contents of the ternary counter 50 are set in accordance with the material of the watch case in this way, the gate circuits 44 to 49 corresponding to each bit output of the ternary counter 50 are opened, so that the contents of the ternary counter 50 are set in accordance with the material of the watch case. Temperature coefficients @at~&a and initial values b1~b depending on the material of the watch case are input to the arithmetic circuit 41. As a result, the arithmetic circuit 41 can perform a predetermined calculation based on the input temperature coefficients and initial values among the temperature coefficients &1 to &1, spinning period values, and -ba.

Next, the display states of FIGS. 186A to 186 will be sequentially explained. First, the content of the ternary counter 30 of the switch control unit 13 is "0", that is, the time mode is set, and one output of the flip-flop 28 is a logical value l! l〃, lines 12 and A3 of the decoder 29
, No. 4.16 outputs a signal with a logical value of 11, which opens the gate circuits 32, 33, 34, and 36 of the display switching control section 11, respectively. As a result, the date information output from the gate circuit 32 is sent to the second numerical display 4, the day of the week information output from the gate circuit 33 is sent to the character display 3, and the date information output from the gate circuit 34 is sent to the second numerical display 4. The output time information is sent to the first numerical display unit 2, and the corrected temperature information output from the gate circuit 36 is sent to the analog display unit 5.
are sent to and displayed respectively. As a result, the display contents of the display device 1 become as shown in Fig. 6). In this case, the displayed temperature on the analog display section 5 is changed every 7 minutes. That is, the /P/ output from the hand clock W&circuit IO
/M signal automatically operates the temperature sensor 6, the Mu/D conversion circuit 16, and the temperature correction circuit 17 at 1-minute intervals, and the temperature detected by the temperature sensor 6 is detected by the Mu/D conversion circuit 1116. After being converted into a digital value, Ta
Correction is performed according to the correction formula of gαm, T + bn,
This corrected temperature is sent to the analog display s5 via the latch 22 and the display switching control section 11. Therefore, the temperature that is automatically measured every 7 minutes is corrected and displayed on the analog display section 5.

Next, in the clock mode, switch S, t! -/times of operation, the output state of the 7-rip 7a knob 28 is reversed by the pulse signal output from the one-shimmit circuit 23,
The Q output becomes a logic value slz, and the logic waxs is output from lines J11, 1!3, No4, Noro, and 17 of the decoder 29.

As a result, the temperature sensor 6, *, /I) conversion circuit 16 is

．． When you operate the , the temperature at that point is measured. That is, while temperature measurements are automatically taken every 7 minutes, switch 8. When the vacuum cleaner is swept, the temperature at that point is measured and
Manual temperature measurement becomes possible for the self-v1 temperature fj11 constant. Therefore, the line J13,i of the decoder 29

36.37 will be opened. As a result, the temperature measured at the time of operation of the switch S is corrected by the humidity correction circuit 17, and this corrected temperature is displayed on the first numerical display 4 (see figure 6).
As shown in the figure, the date information and date information are displayed. In this state, when the switch S is further operated, the output state of the 7-lipfuge 28 is inverted, and its Q output becomes the logical value jFll, so the display returns to the display state shown in Figure 6). .

Next, when the switch S is operated in the state shown in FIG.
The temperature measurement mode is set. In this measurement mode, a signal with a logical value of llll is output from the lines Q4 and (Qs of the differential 1229), and the gate circuits 34, 38, and 39 of the display switching control m11 are opened, and most of the output signals of the lines are displayed as characters. given to body 3. This Pi
As a result, as shown in FIG. 6(0), in addition to the time information being displayed on the first numerical display 2, the Nti positive temperature output from the gate circuit 38 is displayed on the second numerical display 4. ,
In addition, the uncorrected amount outputted from the gate circuit 39 is displayed on the analog display section 5, and furthermore, [T
K-J is displayed, indicating that the display content of the second numerical value display $4 is the uncorrected temperature.

In this measurement mode, the switch S is also turned on.

/ When the same machine is operated, the ternary counter 30 is a pulse signal output from the one-shot circuit 24, and its content is "3".

6.37 will be opened. As a result, the set temperature output from the gate circuit 35 is displayed on the seventh numerical display 2. In this case, the signal g output from the decoder 29 is a logical value IQI, so in the temperature storage circuit 18, the signal g reversed by the inverter 55 opens the dart circuit 53, and the contents of the temperature setting counter 51 are gated. It is sent out via circuit 53. Therefore, the set temperature displayed on the first numerical display 2 is the lower limit of the alarm temperature. Initially, the content of the temperature storage circuit 18 is rOJ, so the displayed set temperature is "0". When setting a desired alarm temperature, for example -s DEG C., in the temperature storage circuit 51, the switches 8 DEG are operated simultaneously. As a result, the pulse signal output from the one-shot circuit 26 is output as a signal 0 from the liner 9 of the decoder 29, and is input to the 1/input terminal of the temperature setting counter 51 of the temperature storage circuit 18. Therefore, a value corresponding to the number of times the switch 84 is operated is set in the counter 51, and this axis is displayed on the 1f) numerical display 2. In this case, in the temperature alarm setting mode, the output signal of the fin Js of the decoder 29 is supplied to the seventh numerical display 2 and the character display 3, so the 61'4 (I)
As shown in the figure, the lower digits of the seventh numerical display 2 are "10".

By displaying "L", it is possible to clearly indicate that the temperature displayed on the first numerical display 2 is the lower limit temperature of the alarm level. In the temperature alarm setting mode, the corrected temperature output from the gate circuits 36 and 37 is the first number tl!, as shown in FIG. 6(I). In addition to being digitally displayed on the display 4, the analog display 5
is displayed in analog form.

Next, in the temperature alarm setting mode, when setting the upper limit concentration of the alarm temperature, first operate the switch SI 7 to invert the output soft part of the flip-flop 28, and set the output to the logical value III. Line λs,i! of decoder 29 s,/7% 713 outputs a signal with logical value #1#.

Therefore, the gauge circuits 3B, 36, 37 are opened, and the signal g also output from the line 113 is input to the temperature storage circuit 18, which opens the gate circuit 55 and opens the gate circuit 54.

In this state, to set the upper limit temperature of the alarm temperature to, for example, 24t'(:), operate the switch S8 2j times.As a result, the pulse signal output from the one-shot circuit 25 is transmitted to the decoder. It is output as a signal f from line λ12 of No. 29, and is input to the +7 input terminal of the temperature setting counter 52 of the temperature storage circuit 18. Therefore, the value corresponding to the number of operations of switch 8.0 is stored in callan #52. is set, and the value set in the counter 52 is displayed on the seventh numerical display 2, as shown in 6th v!J(K). Furthermore, as shown in FIG. 116 (7),
By appropriate means, the upper digits of the seventh numerical display 2 are
By displaying "H", it is possible to clearly indicate that the six-point temperature on the numerical display body 2 of the building/ is a temperature above the alarm temperature.

In this state, when the switch S1 is operated seven more times, the output state of the seven lip 70 knob 28 is inverted and the output Q becomes the logical value pls, so that the display state shown in FIG. 6(D) is returned. Become.

Further, in the state shown in FIG. 6(D), the switch S,
7 more times, the inner world of the ternary counter 3o becomes ``0''.
-1, so the state returns to the state shown in FIG. 6 (4).

Thus, the alarm temperature set in the counter 51.52 of the temperature storage circuit 18 is supplied to the comparison circuit 58.59 via the corresponding gate circuit 56.57 every time the output of the OR gate 15 is given. . Comparison circuits 58 and 59 are
Every time the output of the OR gate 15 is given, the arithmetic circuit 41

When the corrected temperature reaches the lower limit of the alarm temperature, for example -j'(, Sometimes, the comparison circuit 59
An alarm signal is output from the alarm device 20, and an alarm sound is generated from the sound reporting device 20.

In the above embodiment, the temperature correction was performed according to the preset temperature coefficient α and the initial value depending on the material of the watch case, but furthermore, since there are individual differences in body temperature, , set the user's body temperature in advance,
Temperature correction may also be performed taking this set body temperature into account. Furthermore, temperature coefficient αn1 initial value b! ! can be selected depending on the material of the watch case, but only the temperature coefficient and initial value of the case to be used may be fixedly stored.
