Are provided in a circular arc shape on a part of an annular ring having three rows of concentric circles with respect to the rotation axis. Of the three columns of value display units 111, the innermost value display unit 1111 has 10 values ranging from 0 to 9000 in which the values of thousands are changed in order. In the second value display portion 1112 provided outside the value display portion 1111, ten values from 0 to 900 obtained by sequentially changing hundreds of values are arranged in order. In the outermost value display portion 1113, ten values from 0 to 90 obtained by sequentially changing the tens place value are arranged in order. These values may be printed on the dial 11, or may be engraved concave portions or raised convex portions.
That is, in the value display unit 111, a predetermined digit corresponding to each concentric circle is determined.

In these value display portions 1111 to 1113, 10 numerical marks are provided in ascending order at intervals of 12 degrees from a direction (azimuth angle) of 42 degrees clockwise with the 12 o'clock direction as a reference direction. .

In the hour hand 2 of this embodiment, the selection window 202 (first window) provided in a hollow shape at the tip has a length that overlaps each value in the innermost value display 1111. Selection window 20 of hour hand 2
Reference numeral 2 denotes a triangular frame shape. One of the numerical marks of the value display portion 1111 is accommodated in the triangular frame and exposed at the top. The selection window portion 202 is not limited to a hollow shape, and may be provided with a transparent member.

The analog electronic timepiece 1 is a three-hand independent drive electronic timepiece in which hands 2 to 4 are independently driven by separate drive units based on a drive control signal output from the CPU 45. The hour hand drive unit 40, the minute hand drive unit 41, and the second hand drive unit 42 (hereinafter, each drive unit as a drive unit for the plurality of hands 2 to 4 is collectively described as drive units 40 to 42), respectively. It is possible to move the pointers 2 to 4 forward or backward. The set value of the maximum speed at which the drive units 40 to 42 advance the pointers 2 to 4 respectively is twice the set value of the maximum speed to reversely move.

The second hand 4 can be discretely moved to each position of 60 steps per round every 6 degrees. In the time display state, the second hand drive unit 42 moves the second hand 4 forward by one step every second. Hour hand 2
, And the minute hand 3 can indicate each position of 360 steps per turn once.
In the time display state, the minute hand drive unit 41 moves the minute hand 3 forward by one step every 10 seconds. In the time display state, the hour hand drive unit 40 moves the hour hand 2 forward by one step every two minutes.

The oscillation circuit 48 generates a frequency signal having a predetermined frequency, for example, 1.6384 MHz, and outputs the frequency signal to the frequency dividing circuit 49. The frequency dividing circuit 49 divides the frequency signal input from the oscillation circuit 48 by a set frequency dividing ratio, outputs a 1 second signal to the time measuring circuit 50, and outputs a signal having a set frequency used by the CPU 45. It outputs to CPU45.

The timer circuit 50 is a counter that counts a time by counting a one-second signal. Further, the time data counted by the timer circuit 50 can be corrected based on a correction command from the CPU 45.

The CPU 45 comprehensively controls the entire operation of the analog electronic timepiece 1 and performs various arithmetic processes. In the time display state, the CPU 45 outputs a drive control signal to the drive units 40 to 42 based on the time data signal input from the timer circuit 50. When various physical quantities are measured, the movement destination positions of the hands 2 to 4 are determined based on measurement values input from the pressure sensor 53 described later, and the hands 2 to 4 are moved to the movement positions.

The ROM 46 stores various control programs executed by the CPU 45, function programs, and setting data. The function program includes a measured value display processing program for displaying the altitude value calculated based on the measured atmospheric pressure by the hands 2 to 4. CPU
45 reads out a program and setting data from the ROM 46 as needed, develops them in the RAM 47, and executes them. Further, the ROM 46 stores an altitude table 46a indicating a default conversion table between atmospheric pressure and altitude.
The RAM 47 provides a working memory space to the CPU 45. The CPU 45 temporarily stores values obtained by executing control programs and function programs, and settings and calculated values. The RAM 47 also has an altitude table 46a based on the atmospheric pressure state when using the altitude sensor.
And a user setting table 47a determined based on user operations such as unit settings (meters, feet, etc.) for altitude display.

The power supply unit 51 supplies power necessary for driving the CPU 45. Although this power supply part 51 is not specifically limited, For example, it combines a solar cell and a secondary battery.

The pressure sensor 53 is a semiconductor sensor that measures atmospheric pressure using a piezoelectric element, for example.

The operation unit 52 sends an electric signal based on the operation of the buttons B1 to B3 and the crown C1 to the CPU 45 as an input signal. For example, when the button B <b> 2 is pressed, the CPU 45 changes from the time display state to the altitude display state, and displays the altitude on the hands 2 to 4 based on the atmospheric pressure data measured by the pressure sensor 53. Further, when the button B3 is pressed, the CPU 45 sequentially changes the mode from the time display state. When crown C1 is operated, the CPU
In 45, the time is changed manually or the altitude table is corrected.

Next, an operation procedure for performing the altitude display operation in the analog electronic timepiece 1 of the present embodiment will be described.
FIG. 5 is a flowchart showing the control procedure of the altitude display operation by the CPU 45.

In the altitude display process, the button B2 is pressed by the user or the button B3 is pressed,
Started when altitude measurement operation is selected.
When the altitude display process is started, the CPU 45 first sends a command to the pressure sensor 53 to measure the atmospheric pressure (step S11). Further, the CPU 45 sends a command to the second hand drive unit 42 to move the second hand 4 in the direction of 0 o'clock. The CPU 45 includes a minute hand drive unit 41, and
The drive command to the hour hand drive unit 40 is stopped, and the minute hand 3 and the hour hand 2 are temporarily stopped (step S).
12).

When the atmospheric pressure measurement value is input from the pressure sensor 53 to the CPU 45, the CPU 45 reads the altitude table 46a and the user setting table 47a, and converts the atmospheric pressure value into an altitude value. The CPU 45 determines the movement destination positions of the hands 2 to 4 based on the converted altitude value (step S13).

Then, the CPU 45 sends a command to the hour hand drive unit 40 to move the hour hand 2 to the movement destination position (step S14). Subsequently, the CPU 45 sends a command to the minute hand drive unit 41 to give the minute hand 3
Is moved to the destination position (step S15). Finally, the CPU 45 has a second hand drive unit 42.
The second hand 4 is moved to the destination position (step S16). And CPU4
5 ends the altitude display process. In the analog electronic timepiece 1, not only the altitude display but also the atmospheric pressure display can be performed in the same manner based on the measured value of the atmospheric pressure input from the pressure sensor 53.
The atmospheric pressure display process is started, for example, when the button B1 is pressed by the user or the button B3 is pressed and the atmospheric pressure measurement operation is selected. The pointers 2 to 4 are the value display portions 11 respectively.
By selecting and indicating a value included in 11 to 1113, the atmospheric pressure value is similarly represented.

Therefore, the user can easily read a numerical value by reading and adding each digit value.

In particular, the upper digit of the measurement value is indicated by the hour hand 2, the middle digit is indicated by the minute hand 3, and the lower digit is indicated by the second hand 4, so that the user can easily recognize the numerical value intuitively.

The pointers 2 to 4 are provided with hollow selection windows 202 to 402, and the pointers 2 to 4 are
Since the value to be pointed is positioned so as to be included in the selection windows 202 to 402, the selection window 2
The values exposed by 02 to 402 can be easily recognized.

Further, the minute hand 3 intersecting with the value display portion 1111 and the second hand 4 intersecting with the value display portions 1111 and 1112 are provided with transmission window portions 303 and 403 at the intersecting portions, respectively, so that the hour hand 2 and the minute hand 3 Or even when the second hand 4 overlaps, or even when the minute hand 3 and the second hand 4 overlap, all the values included in the selection window portions 202 to 402 are surely recognized without being covered by other pointers. I can do it.

Moreover, since the shape of the selection window portions 202 to 402 is set to a triangle with respect to the rectangular transmission window portions 303 and 403, the value included in the transmission window portion and the selected value can be easily identified. At the same time, the time can be easily recognized when displaying the time by the apex of the triangle.

In addition, since the measurement value obtained by the measuring instrument such as the pressure sensor 53 is digitized and displayed discretely by the pointers 2 to 4 for each digit value, attention is paid to the density of the scale when the analog display is viewed. Measurement values can be read clearly and easily without any problems.

FIG. 10 is a flowchart showing the operation procedure of the measurement value display process in the analog electronic timepiece 1 of the second embodiment.

In the analog electronic timepiece 1 of the second embodiment, the operation procedure of the measured value display process executed by the CPU 45 is the same as the altitude display process executed by the CPU 45 in the analog electronic timepiece of the first embodiment, with the process of step S10 being added. Steps S11 and S12 are performed in step S11.
11a and S12a are respectively changed. Other identical processes are denoted by the same reference numerals and description thereof is omitted.

This measurement value display process is started by inputting a measurement command of any value of temperature, atmospheric pressure, or altitude. When the measurement value display process is started, the CPU 45 first determines which value is to be measured (step S10). The CPU 45 sends a command to cause the pressure sensor 53 or the temperature sensor 54 to perform measurement based on the determination result (step S11a),
