PURPOSE:To also facilitate the comparison of max. atmospheric temp. and min. atmospheric tem., by a method wherein a temp. is displayed by using the hand of an analogue watch having an optical display element used therein to make the watch multifunctional. CONSTITUTION:At the time of a clock mode, an hour hand is displayed when one among an hr display element group 2 is lighted and the hr display element group 2 and a min display element group 3 are lighted at the same angle from the center of a watch main body 1 while a sec display element group 4 is lighted and put out to enable the reading of a sec. When the clock mode is changed over to a thermometer mode by manipulating a crown 6, a temp. graduations display element group 5 is lighted and the temp. at this time is displayed by lighting the hr display element group 2 and the min display element group 3 at the same angle from the center of the clock main body 1 while the max. atmospheric temp. and the min. atmospheric temp. of that day are shown by lighting the min display element group 3 and the sec display element group 4 at the same angle. By this method, the atmospheric temp. at the time, the max. atmospheric temp. and the min. atomospheric temp. of the day are known on sight and, even if the atmospheric temp. at the time is coincided with the max. atmospheric temp. or the min atmospheric temp. of the day, they can discriminated immediately.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multifunctional analog timepiece that includes a thirst meter added to an analog timepiece using an optical display element such as a liquid crystal.

In the past, there were very few analog watches that used optical display elements such as liquid crystals. Although it uses an optical display element, it is not suitable for multifunctionalization. -r This is because analog watches have disadvantages such as having mechanically operated hands that give them a more luxurious image. As for If meters, they are not something that can be easily attached to one's personal belongings. It only shows the temperature at that time and cannot be compared with the highest and lowest temperatures.

There were drawbacks such as.

The present invention was made to eliminate these drawbacks, and uses an optical display element, the phase opening of a Kumquat FC analog clock, to display the current humidity, as well as the highest and lowest atmospheric pressures of the day. This is an analog watch that uses an optical display element and has been made multi-functional, thereby eliminating its cheap image.

FIG. 1 is a plan view showing the entire electronic sub-timepiece of the present invention in timepiece mode. The surface of the watch body 10 is arranged from the center of the watch body 1 to the hour display element group 21 the minute display element group 31 the second display element group 4. There is a depth scale display group 5, and the watch body 1
There is a crown 6 on the right side of the watch. When one hour display element group 2 is lit, the hour hand is indicated, and when the hour display element group 2 and the minute display element group 3 are lit at the same angle from the center of the watch body 1, the minute hand is indicated. There is no second hand for displaying the seconds, and the shift register tx is replaced with a ring counter for the 1-second pulse minute period 9 in FIG. It turned on and off, making it possible to read the seconds. crown 6
is for adjusting the time and switching modes.

FIG. 2 is a plan view showing the entirety of the analog timepiece in thermometer mode when the temperature is indicated using the hands of an analog timepiece using the optical display element of the present invention. When the watch mode is switched to the thermometer mode by operating the crown 6, the temperature scale display element group 5 lights up, and the current mud i, high air temperature, and low air temperature of the day are displayed.

The display method will be explained in detail below.

Since a clock and a thermometer have different scales, the temperature scale display element group 5 is turned on in the hygrometer mode. The temperature at that time is indicated by lighting the hour display element group 2 and the minute display element group 4 at the same angle from the center of the tense body 1, and the highest and lowest temperatures of the day are indicated by the minute display element group 6 and the second display element group 4.
It is shown by lighting it at the same angle as . This determines the temperature at that time.

You can see the highest and lowest temperatures of the day at a glance, and even if the temperature at that time is the same as the highest or lowest temperature, you can easily tell the difference.

FIG. 3 shows an example of a drive circuit for this double watch.

For example, 32.768 KH when in clock mode without switching.
Oscillation circuit 7 using a Z crystal, 32H2 frequency divider 8 that divides it to 52Hz. 1 second pulse frequency divider 9. 1 second pulse that divides the output of the 32Hz frequency divider 8 by 1 second pulse 1. a 1-minute pulse frequency divider 10 that divides the output of the frequency divider 9 into 1-minute pulses; a 12-minute pulse frequency divider 11 that divides the output of the 1-minute pulse frequency divider 10 into 12-minute pulses; There is a clock decoder 13 to which the outputs of a second pulse frequency divider 9, a 1 minute pulse frequency divider 10, and a 12 minute pulse frequency divider 11 are applied. is applied to drive the hour display element group 22 minute display element group 69 second display element group 4. In the thermometer mode, the temperature sensor 14 and its output are applied to the thermometer decoder 17 and the comparison circuit 15, and when the temperature sensor 14 is applied to the thermometer decoder 17, the thermometer decoder 17 responds to the output of the hot water temperature sensor 14. The output is applied to the driver 19 through the mode switching circuit 18 to drive the hour display element group 2 and the minute display element group 3 to indicate the temperature at that time. When the output of the temperature sensor 14 is applied to the comparator circuit 15, it is compared with the maximum temperature and minimum air mixture data in the memory 16, and when it is higher than the maximum temperature or lower than the minimum temperature in the memory 16, the contents of the memory 16 are changed. Rewrite each. The contents of the memo IJ-16 are applied to the thermometer decoder 17, and the output of the hygrometer decoder 17 relative to the output of the memory 16 is applied to the mode switching circuit 18.
The signal is applied to the driver 19 through the signal line, and drives the minute display element group 6 and the second display element group. When the temperature scale display element group 5 enters the thermometer mode, it is similarly driven with an output of 32 Hz. Further, the output of the 12-minute pulse frequency divider is divided into 24-hour pulses by the 24-hour pulse frequency divider 12,
The output of the 24-hour pulse frequency divider 12 is calculated by rearranging the contents of the memory 16 and using the temperature at that time as the highest temperature and the lowest temperature.
Write to memory 16.

As described above, in the present invention, the temperature is displayed using the pointer of an analog watch using an optical display element, so the analog watch using an optical display element can be made multi-functional. , maximum temperature, and minimum temperature can be easily compared, and it also has the effect of improving the image of analog clocks using optical display elements.
