Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides an analog electronic timepiece with a meter that is equipped with two motors that independently drive the hour and minute hands and the second hand, so that the second hand also serves as a meter display. Regarding.

[Conventional technology]

In recent years, various functions have been added to analog electronic watches, making them multifunctional. Some of these multifunctional analog electronic watches display various meters,
Some of these have a meter pointer separate from the hour and minute hands, and others have the time display pointer also used as a meter pointer. As the latest example of the above-mentioned pointer combination system, a system has been proposed in which the hour and minute hands and the second hand are independently driven by separate motors, and the second hand can be rotated forward and backward to display a meter display.

[Problem that the invention seeks to solve]

However, among the devices proposed so far, those in which a meter pointer is provided separately from the time display pointer have a complicated structure and lead to an increase in cost. In addition, when the time display hand is also used as a meter hand, the hour and minute hands display the time in the meter display function, so the hour and minute hands may be at any position within the display range where the second hand displays the meter. As a result, there is a drawback that the meter pointer and hour and minute hands overlap, making it difficult to read, and it is also difficult to judge whether it is in normal time mode or meter mode (・5 points out of 7 points).

SUMMARY OF THE INVENTION An object of the present invention is to provide an analog electronic timepiece with a meter in which the time display pointer also functions as a meter pointer and which has improved readability as a meter.

[Means for solving problems]

The configuration of the present invention for achieving the above object is such that the hour and minute hands are driven by a first motor, the second hand is driven by a second motor, and the second hand is driven by a second motor.
a range regulating circuit for driving the second hand and regulating the range in which the meter is displayed; It is characterized by the provision of an hour and minute hand control circuit.

[Effect]

In the analog electronic timepiece with a meter according to the present invention, in the meter display function mode, the hour and minute hands are fixed at positions that restrict the meter display range, and the second hand moves within the range restricted by the hour and minute hands. is what is displayed on the meter.

〔Example〕 Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 2 and 3, 20 is a display, 21 is an hour hand, and 22 is a minute hand, each of which also serves to indicate the range of the depth meter pointer in the depth meter mode. 26 is a second hand which also serves as a depth meter pointer in the depth meter mode.

In the watch mode shown in FIG. 2, the hour hand 21 and minute hand 22 move every 20 seconds, and the second hand 26 moves every second.

1. The minute hand 22 is moved rapidly and fixed at the starting point (zero meter position) and end point (near the 45 meter position) of the water depth meter pointer 26, respectively, as shown in FIG. At this time, the hour and minute hands stop at the 4:35 position, but this is because the hour hand 21 is connected by the gear train due to the structure of the watch.
and the minute hand 22 are regulated to a certain positional relationship, so when the minute hand 22 is at the 35 minute position (zero meter position), the hour hand 2
1 cannot be set at exactly 45 meters (4 o'clock position).

Therefore, when the upper limit of the display range of the water depth meter pointer 23 is set to 45 meters, the hour hand 21
It is desirable to set the position so that it does not overlap with the . Therefore, the hour hand 21 is set at a position further forward than the 45 meter position as shown in FIG. The second hand 23 is also quickly returned to the zero meter position (35 seconds position), and thereafter the hand moves by one scale each time the diver dives one meter to display the water depth in the range indicated by the arrow.

The first motor 18 drives the hour and minute hands 21,22, and the second motor 19 drives the second hand 23.

Next, the operation of the analog electronic timepiece with depth gauge having the above configuration will be explained.

First, in operating the analog electronic timepiece with depth gauge, the hour and minute hand control circuit 8 and the second hand control circuit 12 are initialized. After replacing the battery, etc., the hour and minute hand control circuit 8
This is to match the contents of the hour and minute hands with the actual positions of the hour and minute hands, and the contents of the second hand control circuit 15 with the actual second hand positions.

First, set the reset switch 13b to ONL,
- Turn on A5, 86, and A7. At this time, switching circuit 1
4 and 16 are both in the selection output state of the human input terminal.

Next, the second hand movement switch 13c is operated to generate an arbitrary number of second movement pulses Ps to move the second hand 23 to the 35 second position, which is the zero position of the depth gauge, shown in FIG.

Furthermore, the hour and minute hand movement switch 13d is operated to generate an arbitrary number of hour and minute hand movement pulses PM to move the hour and minute hands 21 and 22 to the 4:35 position, which is the regulation range shown in FIG. At this time, the display unit 20 is at the 4:35 position where the hour and minute hands 21 and 22 regulate the water depth display range, and the second hand 2
6 is located at the same position as the minute hand 22 and indicates zero meters. In this state, the initial setting switch 13a is operated to generate the initial setting pulse P. is generated and the hour/minute counter 8
a. Hour and minute hand counter 8C1 The initial setting operation is performed by resetting the second counter 12a and the second hand counter 12c and setting the count value of each counter to zero.

By the above operation, the hand position of the hour and minute hands 21 and 22, that is, 4:35, is initialized as zero in the one-minute counter 8a and the hour and minute hand counter 8C, and the hand position of the second hand 23, that is, 35 seconds, is initialized as zero. 12a and the second hand counter 12C are initialized as a count value of zero.

In the watch mode shown in FIG. The C terminal of the OR2 switching circuit 7, and the NOR gate NR3 is connected to the C terminal K of the switching circuit 11.
They each supply an H level signal.

Therefore, the switching circuits 7 and 11 are both connected to the input side I
Hz pulse PA, 1/20 Hz pulse PA are selectively output. Also NAND game) Nl and OR
Since both OR3 supplies H level signals to the hour and minute hand counter 8C and the second hand counter 12c, both counters function as up counters. At this time, both outputs of AND gate Al01All are L.
level, both the -number circuits 8b and 12b are not operating, but since the 1/201'lz pulse pa1 is equally input to the hour and minute counter 8a and the hour and minute hand counter 8c, they always match. ing.

Also, the second counter 12a and the second hand counter 12c also have I.
Since the Hz pulse PA2 is equally input, both always match.

Furthermore, since the reset signal R8 is at the L level, the switching circuits 14 and 16 selectively output the 1/20 Hz pulse PAI and the 111 z pulse PA2, both of which are on the B input side.

At this time, the first drive circuit 15 and the second drive circuit 17 are
Since an H level signal is supplied to the D terminal, both are in the up mode. As a result, the first drive circuit 15 sends the normal rotation drive pulse PDPI to the first motor 18, and the second drive circuit 17 sends the normal rotation drive pulse P02 to the second motor 1? The hour and minute hands 21, 22 and the second hand 26 both display the normal time.

The above is the operation in clock mode.

Next, the operation in depth gauge mode will be explained.

Switching from the watch mode to the depth gauge mode is performed by switching the mode changeover switch B. First, by turning on the mode changeover switch 6, the mode changeover signal Sc is switched to H level. At this time, the mode switching pulse generator 4 generates a mode switching pulse P in synchronization with the rise of the mode switching signal Sc, and sets the R-3FFs 5 and 6 to generate a first fast-forward permission signal S11 and a second fast-forward permission signal. As a result, the AND gate) AI outputs the first fast-forward pulse PI, and the ANDNO gate outputs the second fast-forward pulse P, 2, respectively. At this time, NOR game)
Since both NRI and NR3 are at the L level, the switching circuit 7 selectively outputs the first fast-forward pulse P, 1, and the switching circuit 11 selectively outputs the second fast-forward pulse P, 2, respectively.

Now, let's focus on the operation of the hour and minute hand control circuit 8.

Since the AAND gate Al1 is at L level, the - number circuit 8b is not operating. Further, since the output of the NAND gate N1 is at H level, the hour and minute hand counter 8c functions as an up counter, and the second drive circuit 15 is also in the up mode.

At this time, the hour and minute hand counter 8c indicates the first fast-forward pulse P2.
is counted as fast forward. At the same time, the first fast-forward pulse P,1 is passed through the switching circuit 14 to the first drive circuit 1.
5 and causes the minute hand 22 to move rapidly at 64) 1z. Then, when the hour and minute hand counter 8C reaches the zero position, the zero position detection pulse PL2 is output, and the R signal is outputted via the ANDNO gate and OR gate OR2 which are in the ON state.
-8FF5 by resetting AND game) AI
Turn off.

As a result, the output of the first fast forward pulse P,1 is stopped,
The hour and minute hands 21 and 22 stop fast forwarding at the initial setting position of 1:35, and are fixed.

Also, focusing on the operation of the second hand control circuit 12, since the ANDNO gate is at the L level, the - number circuit 12b is not operating.

Also, OR game) Since the output of OR3 is I-■ level,
The second hand counter 12c functions as an amplifier counter, and the second drive circuit 17 is also in up mode.

At this time, the second hand counter 12c outputs the second fast forward pulse PI2.
is counted as fast forward. At the same time, the second fast forward pulse PI2 is transmitted to the second drive circuit 1 via the switching circuit 16.
7 and causes the second hand 26 to move rapidly at 64 Hz. Then, when the second hand counter 12c reaches the force-zero position, it outputs the zero position detection pulse PL4, and outputs the zero position detection pulse PL4, and outputs the R signal through the AND gate AIO and OR gate (OR4) which are in the ON state.
- AND gate A2 by resetting 8FF6
Turn off.

As a result, the output of the second fast forward pulse P,2 is stopped,
The second hand 26 stops fast forwarding at the 35 second position, which is the initial setting position.

Furthermore, the zero position detection pulse P that resets R-8FF6
At the same time, L4 resets the meter counter 10a constituting the range regulation circuit 1o, and makes the zero meter position of the water depth meter pointer 23 coincide with the zero position of the meter counter 10a of the measurement system. This completes the switch to depth gauge mode.

The operation of the depth meter will be explained below.

For example, if a diver who wears this watch dives 10 meters, the water depth gauge circuit 9 detects the water pressure at that time by the water pressure sensor 9a, and the meter signal generation circuit 9d
At least 10 meter pulses PMD and a polarity signal S of level 1 are output. At this time, since the mode switching signal Sc from the mode switching switch 3 is at H level, the AN
The D gate A9 is in the ON state, and the H level polarity signal S sets the meter counter 10a to the up mode, and also outputs the AND gate A9 and the OR gate OR3.
The second hand counter 12a and the second drive circuit 17 are set to the up mode via.

In addition, if the upper limit signal S and lower limit signal SB of the meter counter 10a are both at L level, i)
Game) The output of NR2 is at H level, and the signal obtained by inverting the second fast forward permission signal S+2 by an inverter is at H level.
Since this is the level, AND game) A4 is in the ON state. Therefore, the meter pulse P. 0 causes the meter counter 10a in the up mode to count 10 times, and causes the second hand counter 12c to count up via the AND gate A4, the OR gate (ORI), and the switching circuit 11.

Furthermore, the 10 meter pulses PMo are supplied to the second first actual operation circuit 17 via the switching circuit 16, thereby causing the second motor 19 to advance 10 steps in the forward direction.

As a result, the water depth meter pointer 23 has 10 scales, that is, 10
Move the hand to the meter position. Further, when the diper dives 3 meters to a total depth of 13 meters, the meter signal generating circuit 9d outputs three meter pulses PMD and H.
Level polarity signal S.

is output, and the meter counter 10a and second hand counter 12
c is added 3 counts for a total of 13 counts.

Further, the water depth meter pointer 26 moves by three scales and indicates 13 meters.

Next, when the diper floats up to a depth of 5 meters, that is, to a depth of 8 meters, the meter signal generating circuit 9d outputs five meter pulses PMD, but the polarity signal SP switches to L level.

As a result, the meter counter is 1゛Oa, the second hand counter is 12
c and the second drive circuit 17 are both switched to the down mode, and the meter counter 10a and the second hand counter 12c
The second drive circuit 17 generates five reverse pulses PDR2 to advance the second motor 19 five steps in the opposite direction, and the depth meter pointer 26 also counts down five times. The hand moves in reverse on the 5th scale and indicates 8 meters.

Then, Daiper dives again and reaches the upper limit of depth 45.
Suppose we reach m. At this time, meter counter 1
0a is an H level upper limit signal S.

Output. NOR game)N by the upper limit signal ST
The output of R2 becomes L level, and A N D gate A4
is turned off, the meter pulse PMD no longer passes, the second hand counter 12c stops at 45 counts, and the depth meter pointer 26 also stops at the 45 meter position.

That is, the display function is stopped for diving exceeding 45 meters. After this, even if the diper dives to 50 meters, the depth meter pointer 23 does not move beyond the 45 meter position, but the meter counter 10a continues to count 50 meters and output the I-I level upper limit signal ST. .

Next, when the diper begins to float, the polarity signal S, switches to L level, so the meter counter 10a starts counting down the meter pulse PMD corresponding to the depth of the float, but the upper limit signal S, remains unchanged. The depth meter pointer 23 does not move as it remains at H level. When the water depth becomes less than 45 meters, the upper limit signal S is switched to L level.

At this time, since the lower limit signal SR is also at L level, NOR
The output of the gate NR2 becomes H level, turning the A N D gate A4 ON again.

As a result, when the water depth reached 44 meters, one meter pulse PMD returned to the ON state and the AND gate A4
, and is supplied to the second hand counter 12c and the second drive circuit 17, and the second hand counter 12c, which is in the down mode due to the L-level polarity signal S, counts down one shot to reach a count of 44. Become.

Similarly, the second drive circuit 17, which is in the down mode, outputs one reversal pulse Pn*2, so that the water depth meter pointer 26 moves in the reverse direction by one scale and indicates 44 meters. Furthermore, each time the diper rises by 1 meter, the meter counter 10au and the second hand counter 12c count down one by one, and the depth meter pointer 23 also moves in reverse by one scale (
·Ku. When the depth reaches zero meters, the lower limit signal S from the meter counter 10a switches to level 11.

As a result, the output of NOR gate NR2 switches to L level, and AND gate 1. By turning on ~4, water depth display will start again. While the electronic watch operates in the depth gauge mode, the hour and minute counter 8a and second counter 12a always count the normal time.

The above is the operation in depth gauge mode.

Switching from the depth gauge mode to the watch mode is performed by turning off the mode changeover switch 6. Due to the immediate switching K, the mode switching pulse PC is supplied from the mode switching pulse generator 4 to the R-3FFs 5 and 6, and the first fast forward permission signal S9. and the second fast forward permission signal SL2 both switch to H level. Then, the first fast forward permission signal 8
．． Since the first and second fast-forward permission signals S12 are both at H level, ]~ND game) Al and A2 are both O.
is in N state, AND game) AI is the first fast forward pulse P
, , , AND game) A2 supplies the second fast-forward pulse P12 to the switching circuits 7 and 11, respectively.

At this time, since the outputs of the NOR gates NRI and NR3 are at L level, the switching circuit 7 outputs the first fast-forward pulse P, 1, and the switching circuit 11 outputs the second fast-forward pulse P, respectively.

Also, since the outputs of the AND game) A2 and A8 are both at the I level, the matching circuits 8b and 12b are in the operating state.Here, if we focus on the operation of the hour and minute hand control circuit 8, , the NAND gate N1 supplies an L level signal to the hour and minute hand counter 8c and the first drive circuit 1.
8 in the down mode, the hour and minute hand counter 8
c is the first drive circuit 1 that counts down the first fast-forward pulse PL1 and is simultaneously supplied with the first fast-forward pulse Pl.
5 outputs a reverse hand movement pulse P o II I, and the hour and minute hands 21 and 26 start reverse fast forwarding. When the contents of the hour and minute hand counter 8c match the contents of the hour and minute counter 8a, a coincidence pulse PL1 is outputted from the coincidence circuit 8b.

This coincidence pulse PL+ is passed through the OR gate (OR2) to R-
By resetting 8FF5, AND gate A1 is turned off and the output of N0I (game) NRI is set to l-.
Switch to I level.

As a result, the hour and minute hands 21 and 22 are fast-forwarded in reverse to the normal time position, completing the correction operation. And the switching circuit 7
1 / 2011z Pulse PA1 is selected, returns to the beginning of the sentence, and thereafter the hour and minute hand counter 8c and the hour and minute counter 8a are set to 1.
/2011z Pulse PA1 is counted up, and the hour and minute hands 21.22 also move in 20 second increments to display the normal time.

Next, focusing on the operation of the second hand control circuit 12, the inverted signal obtained by inverting the second fast forward permission signal S, 2 by the inverter is at the L level, so A4 is at the L level.
F' F. An inverted signal obtained by inverting the mode switching signal Sc by an inverter is sent to the second hand counter 12c and the second drive circuit 17 through the OR gate OR3.
Since an H level signal is supplied to the terminal, the second hand counter 12c counts the second fast forward pulse P12.

At the same time, since the second fast-forward pulse P,2 is also supplied to the second drive circuit 17, the second drive circuit 17 outputs the normal fast-forward pulse PDF2 to fast-forward the second hand 26 in the normal rotation. When the contents of the second hand counter 12c and the contents of the second counter 12a match, the minus number circuit 12b
A matching pulse PL3 is output. This coincidence pulse P
L, turns off AND gate A2 by resetting R-3FF6 via OR gate OR4, and switches the output of NOR gate NR3 to H level.

As a result, the second hand 23 is rapidly forwarded forward to the normal time position, and the correction operation is completed. Then, the switching circuit 11
The state returns to the selection state of Hz pulse PA2, and thereafter the second counter 12a and second hand counter 12c select 1 tlz pulse PA.
2 and the second hand 26 also moves in 1 second increments to display the normal time.

FIG. 4 shows another embodiment of the present invention, and is an example of a depth gauge mode in which the hour and minute hands 21 and 22 are set at the 12 o'clock position, and 60 meters with the zero second position as zero meters. It is a total. That is, by setting the hour and minute hands 21 and 22 to overlap the 12 o'clock position, the starting and ending points of the depth gauge are set at the same position, and the entire circumference is set as the display range of the depth gauge.

The above embodiment in FIG. 4 can be constructed by using the circuit configuration in FIG. 1 as is and simply changing the set values for each counter.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, by fixing the hour and minute hands at the start and end points of the meter pointer, the meter pointer and the hour and minute hands overlap, making it difficult to read.
This solves the drawback that it is difficult to determine whether it is in watch mode or meter mode, and the above configuration makes it possible to realize an analog electronic watch with a meter that has extremely high visibility.
