Further, in the present invention, the analog / digital conversion circuit converts analog data into digital data in a data format suitable for digital signal amplification in the amplification means.

Further, according to the present invention, the sampling frequency of the analog / digital conversion circuit is set to a frequency sufficiently higher than the frequency of the standard radio signal.

According to the present invention, when the control means is in the alarm sound command, for example, the alarm setting time or the hour, or when the monitor switch is input, the alarm sound data is read from the alarm sound data holding means. It is output to the amplification means. The amplifying means amplifies the sound information data with a predetermined gain and applies it to the sound means as a drive signal. As a result, the sound corresponding to the sound data is emitted from the sound generating means. Therefore, even during sounding, the standard radio signal can be received and the time can be adjusted with almost no influence of noise or fluctuation of the power supply voltage.

Further, according to the present invention, the control means is a sounding command, for example, an alarm setting time or an hour.
Alternatively, when the monitor switch is input, the report sound data holding means outputs the report sound data as an analog signal to the analog / digital conversion circuit. In the analog / digital conversion circuit, the amplification means converts the analog data into digital data in a data format suitable for digital signal amplification, and outputs the digital data to the amplification means. The conversion from analog data to digital data is performed at a sampling frequency sufficiently higher than the standard radio signal frequency of 40 kHz or 60 kHz. In the amplification means,
The report sound data is amplified with a predetermined gain and applied as a drive signal to the report sound means. As a result, the sound corresponding to the sound data is emitted from the sound generating means.

Further, as shown in FIG.
The fifth wheel & pinion 122, the second hand wheel 123, the third wheel & pinion 133, the minute hand wheel 134, and the hour hand wheel 136 are all arranged at the same time. Then, the through hole 122 of the first fifth wheel & pinion 122.

When 36e) are overlapped with each other, the detection light emitted from the light emitting element 142 is received by the light receiving element 144 and outputs that the second hand, the minute hand and the hour hand point to positions such as the hour.

Further, the light emitting element 142 is composed of the upper case 11
2 is arranged in a mounting recess 112c serving as a first disposition portion formed so as to open to the outside of the second mounting recess 112c, and a circular through hole 112d having a predetermined diameter is formed on the bottom surface of the mounting recess 112c.
Has been opened. The circular through hole 112d has a property that the detection light emitted from the light emitting element 142 spreads in a divergent shape, so that the light in the spread portion is blocked and only the converged light is allowed to pass therethrough to prevent erroneous detection. It is something to do. Similarly, the light receiving element 144 includes the lower case 11
1 is arranged in a mounting recess 111c serving as a second disposing portion that is formed so as to open to the outside of 1, and a circular through hole 111d having a predetermined diameter is formed on the bottom surface of this mounting recess 111c.
Has been opened. The circular through hole 111d is for allowing only the light emitted from the light emitting element 142 and passing through the through hole to pass through as much as possible to prevent erroneous detection.

When the first fifth wheel 122, third wheel 133, second hand wheel 123, minute hand wheel 134 and hour hand wheel 136 are mounted, a predetermined positioning pin is used as a circular through hole 111d of the lower case 111 for positioning. Each of the through holes and the circular through hole 112d of the upper case 112 are sequentially assembled so as to penetrate therethrough. Then, after the upper case 112 and the lower case 111 are joined and integrated, the positioning pin is pulled out to mount the light emitting element 142 in the mounting recess 112c in which the through hole 112d is located.
The light receiving element 144 is mounted in the mounting recess 112c where 1d is located.

As a result, the through holes 112d and 111 are formed.
d is completely closed, and the upper case 112 and the lower case 11
External light can be prevented from entering the internal space defined by 1. Therefore, it is possible to prevent erroneous detection due to invasion of external light, and since it also serves as a positioning hole during assembly and a through hole for light detection, compared to the case where these holes are provided separately. The device can be integrated and downsized.

As shown in FIGS. 5 and 6, the manual correction system 150 includes a back wheel 135 on the day that meshes with the small diameter gear 134b of the minute hand wheel 134 and a large diameter gear 136a of the hour hand wheel 136, and a back wheel 135 of the day. The manual correction shaft 151 has a gear 151a that meshes with the large diameter gear 135a of the back wheel 135. This manual correction shaft 151 is used for the upper case 1
A head 151b positioned outside 12 and allowing the user to directly touch his / her finger, and a protrusion formed on the lower case 111 through the opening 112e formed on the upper case 112 and extending from the head 151b. A columnar portion 151c pivotally supported with respect to 111e, and a gear 151a is formed in a region below the columnar portion 151c.

The manual correction shaft 151 is constructed so as to rotate in the same phase as the minute hand wheel 134, and when the minute hand wheel 134 is being driven by the above-mentioned second drive system 130, it passes through the day back wheel 135. While rotating in the same phase as the minute hand wheel 134, when the second drive system 130 is not operating, the head 15
The pointer position can be manually corrected by rotating 1b with a finger.

As described above, the second hand shaft 12 of the second hand wheel 123 is
3b is inserted into the minute hand pipe 134p of the minute hand wheel 134,
Since the minute hand pipe 134p of the minute hand wheel 134 is inserted through the hour hand pipe 136p of the hour hand wheel 136, the second hand wheel 1
23, the minute wheel & pinion 134, and the hour wheel & pinion 136 have a common rotation center axis, and when displaying the time,
The second hand is rotated once every 60 seconds, the minute hand is rotated once every 60 minutes, and the hour hand is rotated once every 12 hours.

At the tip of the minute hand pipe 134p of the minute hand wheel 134 and at the tip of the hour hand pipe 136p of the hour hand wheel 136, as shown in FIG. 16, a first index for positioning that extends in a radial direction with a predetermined width. 134g as a groove and a groove 136g as a second index are formed. The groove 134g and the groove 136g are set to indicate a predetermined time, for example, 12:00 when they are aligned.

By providing such a positioning index, the minute hand wheel 134 and the hour hand wheel 136 are attached to the lower case 111.
Even after being covered and covered with the upper case 112, it can be seen that the grooves 134g and 136g are aligned in a straight line to indicate a preset approximate time. The hour hand can be easily attached, other alignment and position confirmation steps are unnecessary, and the manufacturing time and the inspection time on the manufacturing line and the inspection line can be shortened. The positioning index is not limited to the above groove, but may be a mark such as a potch.

Next, the operation of the above configuration will be described.

When the CPU 13 receives a sounding command, for example, a reference signal near the alarm set time from the timepiece main body 14, it is on the hour, or when the monitor switch 6b is input, a sound is output from the memory 9. Voice data as alarm data for power-up alarm and predetermined sound information data are read out, and are read through the bus BS and I / O port 17
It is supplied to the amplifier 10 bit by bit. In the amplifier 10,
The audio data such as voice data read from the memory 9 is received bit by bit, and the digital signal is amplified as it is by the ultra-high-speed sampling of 2.8 MHz and the high-order ΔΣ modulation processing.
Is output to. The LPF 11 extracts the low frequency component of the digital report sound data amplified by the amplifier 10 and outputs it to the speaker 12. The speaker 12 is driven by the output signal of the LPF 11 and produces a sound according to the predetermined report sound data read from the memory 9 by the CPU 13.

At this time, the radio-controlled timepiece 1 receives the standard radio-wave signal and adjusts the time with almost no influence of noise or fluctuations in the power supply voltage even during sounding.

Next, the time correction operation of the radio-controlled timepiece 1 will be described.
Focusing on the control operation in the CPU 13, FIG.
This will be described with reference to 1.

When the receiving switch 12 is turned on by the user, for example, various states are returned to the initial state in the CPU 13 and the forced correction mode is set (ST101). At this time, for example, the pointer is stopped and the liquid crystal display panel 30
The calendar display including the date, the day of the week, and the like displayed in is initialized. Further, since the receiving switch 6d is turned on, driving power is supplied from the CPU 13 to the standard radio signal reception system 2, for example, and the standard radio signal reception operation is performed (ST102).

For example, in the long wave receiving circuit 2b of the standard radio wave signal receiving system 2, after the received signal from the antenna 2 is amplified, it is demodulated by the detection circuit, converted into a binary signal by the waveform shaping circuit, and converted into a digital time code. It is output as a signal.

After the receiving operation of step ST102, if the receiving state is within the reference range and the button correction mode is not set (ST103, ST104), the operation moves to the next pointer position detecting operation (ST105).

When it is determined in step ST103 that the correction button has been input, and in step ST
If the reception state is out of the reference range in 104, the same pointer position detection as in step ST105 is performed (ST1.
07), the process proceeds to step ST108.

Next, the pointer position detecting operation in step ST105 will be described with reference to FIG. First, the CPU
At 13, the elapsed time counter is reset (ST1
51), and shifts to the pointer fast-forward operation (ST152).

As shown in FIG. 20, the needle fast-forward operation is as follows.
First, the pulse signal output pattern for hour, minute, second is set from the CPU 13 (ST521), and the drive signal signal DR ₂ is set.
Is output to the drive circuit 18 at a low level. As a result, the transistor Q ₂ is turned on and the detection light is emitted from the light emitting element 142, that is, the light emitting diode.

Then, the CPU 13 outputs the first and second control signals CTL ₁ and CTL ₂ , and the second hand stepping motor 121 and the hour / minute stepping motor 1 are output.
31 is pulse-driven (ST522).

Then, a desired time, for example, 32 ms
Is counted, and when the counting is completed (ST52
3), first and second control signals CT from the CPU 13
When the outputs of L ₁ and CTL ₂ are stopped, the second hand stepping motor 131 and the hour / minute stepping motor 131
Pulse driving is stopped (ST524).

Next, the CPU 13 with the polarity reversed.
The first and second control signals CTL ₁ and CTL ₂ are output from (ST525), and it is determined whether or not it is the first second (ST526). In the case of the first second, the time counter is incremented. (ST527), and the elapsed time counter is incremented (ST528).

Then, the optical sensor 140 is driven so that the input state of the detection signal DT ₁ can be checked (S
T529).

If it is determined in step ST526 that it is not the first second, step ST526.
Proceed to 529.

Then, a desired time, for example, a time of 16 ms is counted, and when the counting is completed (ST53
0), the process proceeds to the next step ST153.

Next, the output pattern of the optical sensor 140 is discriminated (ST153). Here, the time adjustment by comparing the output pattern with the pattern stored in advance is performed by matching with any one of the three types of patterns.

That is, as shown in FIG. 21A, the output pattern of the phototransistor by the minute hand wheel 134 has two narrow B widths as the OFF width on which the light shielding portion acts.
Part and one wide A part appear alternately, and the output pattern of the phototransistor by the hour hand wheel 136 has an off width in which the light shielding part acts, as shown in FIG. A pattern in which three types of D, E, and C parts appear alternately at a predetermined interval, and an output pattern obtained by combining the two is a D, B, and A part as shown in FIG. Three types of patterns, that is, a pattern in which parts are combined, a pattern in which parts E, B and A are combined, and a pattern in which parts C, B and A are combined, are patterns that appear at predetermined intervals. . Note that, among the patterns shown in FIG. 21, the part of the pattern which is turned on is actually a part of the pattern which is turned off by the light-shielding portion of the third wheel & pinion 133, and therefore has a toothless pattern.

Therefore, when the pattern composed of the combination of the D section, the B section and the A section is confirmed, for example, 4:00
For example, 8:00 when a pattern composed of a combination of minutes, E, B and A is confirmed, and when a pattern composed of a combination of C, B and A is confirmed, for example, 12:00 Set and set it as 00 minutes beforehand. Then, comparing with this set pattern, 1
Whether the position is 2:00 or not (ST154),
It is determined whether or not the position is 4:00 (ST155), 8:00
It is determined whether or not it is the 0 minute position (ST156).

Then, step ST154, step S
In any of T155 and step ST156, if it is determined that the position is different, step ST15
Return to processing of 2.

Further, step ST154, step ST
If it is determined that the position is the predetermined position in any of the processes of 155 and ST156, the process returns to the predetermined process.

Next, the fast forward correction operation of the hour hand for analog display of time is performed (ST106). In the fast-forward correction operation of the pointer, the first and second drive signals CTL ₁ and CTL ₂ are sent to the stepping motor 121 for the second hand and the stepping motor 1 for the hour and minute hand according to the value of the time counter.
It is output to 31 and is rotationally driven by fast-forwarding, and the pointer position is corrected to the time of the time counter.

When the reception state is outside the reference range, "not possible", and when the reception state is within the reference range, "good"
Is set (ST108).

When the oscillation circuit 19 counts one second (ST109), the internal clock 13a
In the time counter, the count is incremented by 1 second (ST110). Then, the first control signal CTL
₁ is output and the second hand stepping motor 121 is pulse-driven (ST111).

Then, the control signal CTL ₂ is output every 10 seconds in the time counter, and the second hand stepping motor 131 is pulse-driven (ST112).

Then, the set reception state is "impossible".
In this case, the drive signal DR ₁ is output to the drive circuit 15, and the light emitting element 16 as the notification means emits light to notify the user that the radio signal can hardly be received.

In the normal correction mode, if the button correction mode is not set (ST114), it is judged whether or not the reception time is preset (ST11).
5) If it is not the set time, it is determined whether or not it is the position detection time, for example, 12:00:00 am (ST116), and the process proceeds to step ST23.

When it is determined in step ST116 that it is not the position detection time, the process returns to step ST109.

In step ST114, when the correction switch 13 is turned on to shift to the button correction mode, a predetermined button correction operation is performed (ST117). Then, the process proceeds to step ST122.

When it is determined in step ST115 that the time is the automatic reception time, the standard time radio signal is received (ST118). In the reception operation of step ST118, it is determined whether or not reception is impossible (ST1
19) If the reception is good, it is determined whether or not there is a difference from the internal clock.

When it is determined in step ST119 that the reception is impossible, and when it is determined in step ST120 that there is no difference between the internal clock 13a and the received time, the process proceeds to step ST122. .

When it is determined in step ST120 that there is a difference from the internal clock 13a, the fast-forward correction is performed (ST121).

At step ST122, when the reception state is within the reference range and when the correction button is input, "impossible",
When the reception state is within the reference range, "good" is set, and the process returns to step ST109.

Then, in step ST116, if it is determined that it is the position detection time by determining whether it is the position detection time or not, the process proceeds to step ST123.

At step ST123, the drive signal D
R₂ Is output to the drive circuit 18 at a low level. This
As a result, the transistor Q₂ Turns on and the light emitting element 142
The detection light is emitted from. Then, the light receiving element 144
The phototransistor turns on and the detection signal DT ₁ Ha
Level (power supply voltage V_CCLevel) to low level
It is discriminated whether or not it has been changed (ST123),
If it is switched to the bell, the process of step ST109 is performed.
Return to ri.

In step ST123, for example,
At 12:00 am, which is the position detection time, when the light receiving element 144 does not switch to the low level, that is, when the hour, minute and second hands are not aligned, the frequency of the state where they are not aligned is determined. (ST124).

For example, if it is determined that the unaligned state appears at least once a month, for example, the drive signal DR ₁ is sent at regular intervals.
5, the light emitting element 16 is made to blink, a warning is displayed to the user (ST125), and the process returns to step ST109.

If it is determined in step ST124 that the number of unaligned states is less than or equal to the predetermined number of times, the pointer position detection process is performed (ST126).

The process of step ST126 is the same as the process of step ST105, and therefore its description is omitted.

Then, it is determined whether or not the elapsed time is abnormal (ST127), and when it is determined that the elapsed time is abnormal, the process returns to step ST126 again.
That is, for example, if position detection is performed from the position of 12:00, which is the position detection time, the next stop position is 4:00.
Since it is determined to be 0 and 8:00, it is possible to determine whether it is normal or not by the sending time.

If it is determined in step ST127 that the elapsed time is not abnormal, the internal clock 13
Until it coincides with a, the control signals CTL ₁ and CTL ₂ are output to the stepping motor 121 for the _second hand and the stepping motor 131 for the hour and minute hands to rotate and drive at fast forward, and the pointer position is corrected at the time of the internal clock 13a. (ST
128) and the process returns to step ST109.

As described above, in the correction operation of the hands, the minute hand wheel 134 and the hour hand wheel 136 use the arc-shaped through holes, that is, the long holes as the through holes for allowing the detection light to pass therethrough. The range in which is turned on is widened, the position detection time can be shortened, and as a result, the time for adjusting the time of the second hand can be shortened. In addition, hour wheel 1
Since 36 types of light-shielding parts C, D, and E are provided in 36,
You can detect any of the points and correct the time,
Further, the position can be detected only by rotating the hand wheel 136 at the slowest rotation speed by approximately 1/3 of the rotation of the conventional wheel 136.
The time at which the time of the minute hand 203 and the hour hand 204 is adjusted can be shortened.

As described above, according to the present embodiment, in the self-correcting timepiece with a sound reporting function for adjusting the time by receiving the standard radio wave signal including the standard time information of the predetermined frequency,
Memory 9 for holding sound data as digital data
An amplifier 10 that amplifies the digital report sound data as a digital signal and outputs it as a drive signal; and a speaker 12 that is driven by the drive signal from the amplifier 10 via the LPF 11 to generate a sound according to the report sound data. Since the CPU 13 which receives the sound report command and outputs the digital report data stored in the memory 9 to the amplifier 10 is provided, the standard radio wave can be received even during the sound generation without being restricted, and the current consumption can be reduced. Therefore, there is an advantage that the battery life can be extended.

Second Embodiment FIG. 22 shows a second embodiment of the radio-controlled timepiece with sound reporting function according to the present invention.
2 is a system configuration diagram showing the embodiment of FIG.

The difference of the second embodiment from the first embodiment described above is that a sound source device (IC) 40 for outputting report sound data such as a melody as an analog signal is provided in the preceding stage of the amplifier 10, The ADC 41 that converts the signal into a digital signal and supplies the digital signal to the amplifier 10 is provided. Note that in the configuration of FIG. 22, a recording system such as a microphone is not provided.

In such a structure, when the CPU 13 receives a warning sound command, for example, a reference signal near the alarm set time from the timepiece main body 14, it is on the hour, or when the monitor switch 6b is input, the sound source. Device 40
To output sound data to the ADC 41. ADC41
Then, the analog data is converted into digital data in a data format suitable for the amplification of the digital signal of the amplifier 10,
It is output to the amplifier 10. This analog data is converted to digital data by using the standard radio signal frequency of 40 kHz.
Alternatively, the sampling frequency is sufficiently higher than 60 kHz. The amplifying means amplifies the sound information data with a predetermined gain and applies it to the sound means as a drive signal. As a result, the sound corresponding to the sound data is emitted from the sound generating means. Therefore, even during pronunciation
