Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pointer-type alarm electronic timepiece having a function of generating an alarm sound.

In conventional alarm clocks that display the time using hands and a dial, the alarm occurrence time is generally set using a reference hand, but with this method, the setting error is very high in extremely high-precision electronic clocks, etc. is too large.

In order to reduce setting errors, for example, clocks have been proposed which are provided with a separate time counter and a memory circuit for storing the alarm occurrence time.

However, when setting the time at which an alarm sound is generated in a watch incorporating such a time counter and memory circuit, it is impossible to accurately set the time unless the set time is displayed in some other way.

For this reason, it is conceivable to use the display section of a so-called calendar clock, which conventionally displays the day of the week or B-ft, to display the alarm setting time instead of the day of the week or date. A disc with letters and numbers printed on it, which can be rotated to change the content displayed in the window provided on the dial.

Therefore, for example, if the disk that conventionally displayed the day of the week displays the hour unit of the alarm setting time, and the disk that conventionally displayed the date displays the minute unit, then the hour If the alarm is set in a 24-hour display, it is easy to distinguish whether the alarm is set in the morning or in the afternoon, but the displayed numbers will be extremely small.

For this reason, if the hour is displayed in a 12-hour format, the numbers displayed will be large, but it will be extremely difficult to distinguish between morning and afternoon.

Accordingly, the present invention provides an alarm electronic clock that allows the operator to determine by sound which time zone the set alarm occurrence time is in when a switch for setting the alarm occurrence time is operated. The details will be explained based on examples.

FIG. 1 is a plan view showing the external appearance of an alarm electronic timepiece according to the present invention, and reference numeral 1 indicates an outer case.

A crown 2 is provided on the side surface of the exterior case 1.

A dial plate 3 is provided on the upper surface of the exterior case 1, and a window portion corresponding to the hour plate 5 and the division plate 6, which are provided at the bottom of the dial plate 3 and serve as a display unit for displaying the alarm occurrence time, is provided in a part of the dial plate 3. 4
is formed.

An hour hand 7 is attached to the tip of an hour wheel pipe (not shown) extending above the dial, and an hour hand 7 is attached to the shaft of the second wheel (not shown) passing through the pipe and extending above it. minute hand 8
is installed.

FIG. 2 is a block diagram showing the circuit section of the alarm electronic timepiece according to the present invention, and reference numeral 9 is an oscillation circuit including a crystal oscillator or the like.

The oscillation output signal obtained by the oscillation circuit 9 is frequency-divided by the frequency dividing circuit 10 into a reference signal having a frequency that serves as a reference for time measurement.

The output of the frequency dividing circuit 10 is supplied to a drive pulse generation circuit 11, and the output of the drive pulse generation circuit 11, that is, the drive pulse, is supplied to a converter 12 such as a step motor.

The converter 12 is driven by the drive pulse, and the operation of the converter 12 mechanically drives the clock mechanism 13 including the hour hand 71, minute hand 8 (shown in the first diagram), and the like.

On the other hand, numeral 14 is a seconds counter that has a sexagesimal counter and a quinary counter in tandem, and outputs a 5-minute carry.
The carry is supplied to the hexadecimal force rank 15.

The carry of the minute counter 15, that is, the pulse with a period of one hour, is supplied to the hour counter 16 in base 24.

Count outputs output from the minute counter 15 and hour counter 16 in BCD codes are supplied to a matching circuit 19.

The coincidence circuit 19 is also supplied with the respective memories of a minute memory circuit 17 consisting of a decimal counter and an hour memory circuit 18 consisting of a 24-base counter.

Reference numeral 20 is a switch that is turned ON once by rotating the crown 2 shown in FIG. It is something to remember.

The switch 21 is turned on once by turning the crown 2 (first illustration) clockwise once from the first drawer position, and this switch 21 stores the alarm occurrence time in the hour memory circuit 18 in units of one hour. It is something that makes you

The switch 22 is a switch that is turned on when the crown 2 (shown in the first diagram) is changed from the second pulled out position to the first pulled out position, and thereby the minute and hour memory circuits 17.1
8.

The switch 23 is a switch that is turned ON when the crown 2 (shown in the first figure) is positioned at the second drawer position. All counters 14-16 are reset.

A high potential voltage VDD of the power supply voltage is applied to one end of the switches 20 to 23.

The output of the coincidence circuit 19 described above is supplied to a control circuit 24 which is supplied with a frequency division signal from a predetermined frequency division stage of the frequency division circuit 10.The output of the control circuit 24 is supplied to an alarm drive circuit 25. .

The output of the alarm drive circuit 25 is supplied to an electroacoustic transducer such as a speaker.

The operation of the alarm electronic timepiece according to the present invention having such a configuration will now be described.

The oscillation output signal of the oscillation circuit 1 is divided by the frequency dividing circuit 10,
For example, the frequency is divided to a reference signal of IHz, and the drive pulse generation circuit 11 generates two drive pulses with opposite phases based on the reference signal and supplies them to the converter 12.

The converter 12 is driven by the drive pulse, and the clock mechanism 13 is mechanically driven thereby to display the time using the hour and minute hands 8.

Next, if the time when you turn on the power to the watch is, for example, 9 a.m.
Assuming that the time is 59 minutes, set the alarm occurrence time below.
The operation of each part due to time correction etc. will be explained.

When the power is turned on, the pointers 7, 8 and each counter 14~
16. The contents of each of the memory circuits 17 and 18 are uncertain.

Therefore, first turn crown 2 (shown in the first diagram) from the normal position to 1.
The user pulls out the drawer to the drawer position of the second stage, rotates the crown 2 to the right and left, respectively, and sets the alarm generation time displayed on the window 4 (first illustration) of the dial 3 to 10:00 AM.

In this case, since numbers are printed on the hour plate 5 in units of 1 hour and numbers printed on the division plate 6 in units of 5 minutes, the setting of "minutes" is performed in units of 5 minutes.

Further, to distinguish between morning and afternoon, a control circuit 24, which will be described in detail later, is configured, and a switch interlocked with switch 21 produces an identification sound only in the afternoon while the switch is ONL, or This can be done by generating different identification tones.

In this way, the display content on the window section 4 is set to 10:00 am.

At this time, a certain number, that is, a number corresponding to the operation of the crown 2, is stored in each of the hour, minute, and hour memory circuits 17 and 18.

Thereafter, the crown 2 is positioned at the second pulled out position.

As a result, the switch 23 is turned on, and the frequency division and
Bribe 101. The drive pulse generation circuit 11 and the second, minute, and hour counters 14 to 16 are all reset. In this state, rotate the crown 2 to set the hour hand 7 and minute hand 8 to 10:00.
Set to indicate 0 minutes.

Next, as soon as the time reaches 10:00, turn the crown 2.
Push it to the normal position.

This allows the crown 2 to move from the 2nd drawer position to the 1st position.
The switch 22 is turned on while changing to the drawer position of the second stage, and the minute and hour registers (indication circuits 17 and 18 are reset).

In this state, the converter 12 and the counters 14 to 16 perform normal operations.

Next, when setting the alarm generation time to 3:05 p.m., for example, first pull out the crown 2 (shown in the first figure) to the first drawer position and rotate the crown 2 clockwise five times.

As a result, the switch 21 is turned on five times.

Therefore, the time memory circuit 18 has f! 521 is stored.

Next, rotate crown 2 once to the left.

This turns on the switch 20 once. Therefore, "1" is stored in the minute storage circuit 17.

'5'' is stored in the time storage circuit 18,
The window 4 of the dial 3 displays 03'', the minute storage circuit 17 stores 1', but the window 4 of the dial 4 displays 05.

This is because the minute counter 15 and the minute memory circuit 1γ are configured in a decimal format, and the minute counter 15 contains 30
Since pulses with a period of 5 minutes are supplied from the 0-base second counter 14, it can be easily understood that the content is 5 minutes in terms of time compared to 1''.

By doing so, the second counter 14 becomes complicated, but the circuit configurations of the minute counter 15, minute storage circuit 17, and matching circuit 19 can be simplified, and the division plate 6 that displays in units of 5 minutes can be simplified. (as shown in the first diagram), the crown 2 that operates the crown 2, and the hinges that operate the crown 2 can be simplified.

In this state, when the time reaches 3:05 p.m., the count contents of the minute counter 15 become l l t+ and the hour counter 16
The count content becomes 5''.

As a result, the matching circuit 19 detects that the contents of the minute counter 15 and the minute storage circuit 17 match, and that the contents of the hour counter 16 and the hour storage circuit 18 match, and outputs a fixed time detection signal.

The control circuit 24 to which the detection signal is supplied outputs a predetermined alarm signal while the detection signal is being supplied, and supplies it to the alarm drive circuit 25, as will be described in detail later.

The alarm drive circuit 25 amplifies the supplied alarm signal and supplies it to the electroacoustic transducer 26.

The outline of the alarm electronic timepiece according to the present invention has been described above, and a specific example of its main part, that is, the control circuit 24, will be shown and explained below in FIG.

FIG. 3 is a circuit diagram showing a first embodiment of the control circuit 24 in FIG.
This is a switch installed in the section.

This switch 27 is a switch that is turned on once just before '12' is displayed on the window 4 of the dial plate 3.

Therefore, when the time plate 5 is rotated twice by rotating the crown 2 (first illustration), the switch 27 is turned ON twice, and the switch signal obtained by this switch 27 is transmitted to the inverter 28.
The signal is supplied to a terminal CL of a flip-flop circuit (hereinafter abbreviated as FF) 29 via the gate terminal CL.

The Q output of the FF 29 is supplied to a two-man powered AND circuit 30, one input terminal of which is supplied with the first frequency-divided signal in the audible range from the frequency divider circuit 10 (second diagram).

The output of the AND circuit 30 is connected to the switch 2 shown in FIG.
A two-man powered OR circuit 3 via a switch 31 linked to 1
3.

On the other hand, the first frequency-divided signal supplied to the AND circuit 30 is supplied to a three-man powered AND circuit 32 together with another relatively low-frequency second frequency-divided signal.

The remaining input terminal of the AND circuit 32 is connected to the coincidence circuit 19 (second
A detection signal is supplied from the
supplied to

The output of the OR circuit 33 is supplied to the alarm drive circuit 25 (shown in the second figure) as an alarm signal and an identification signal.

The operation of the control circuit having such a configuration will be explained next.

First, the Q output of the FF 29 is determined by the switch 27, which is turned ON-OFF by the rotation of the time plate 5 (shown in the first diagram).
1" is assumed to be in the afternoon.

Now, the Q output of FF29 is logic [in the old case, window 4 of dial board 3]
When "10" is displayed in (the first diagram), it is difficult for the user to determine whether the alarm generation time is around 10 a.m. or around 10 p.m.

Then, the crown 2 (shown in the first figure) is rotated one turn in the right direction at the first pulled out position.

As a result, the switch 31 is turned ON once by the force LFF2.
Since the Q output of 9 is logic "0", no signal is output from the OR circuit 33, and no sound for identifying the time zone is generated.

This allows the user to know that the alarm occurrence time displayed on the window 4 (first illustration) is in the morning.

On the other hand, when the crown is operated, the window 4 appears at °゛11''.
is displayed.

Further, when the crown 2 is rotated so that the display on the window 4 becomes "12", the switch 27 turns ON L, FF29
The Q output of changes to logic "1".

As a result, the switch 31, which is turned on immediately thereafter, generates an identification sound for a short period of time.

Thereafter, while 12'' is displayed on the window 4 of the dial 3, an identification sound is generated only once for each rotation of the crown 2.

By generating such an identification sound, the user can know that it is the afternoon time zone.

On the other hand, when the alarm generation time is reached, a detection signal is supplied from the coincidence circuit 19 (second diagram) to the AND circuit 32.

As a result, the first frequency-divided signal is modulated into the second frequency-divided signal, which is output from the OR circuit 33 as an alarm signal.

Note that the morning and afternoon time zones can be determined based on the Q output of the FF29.When the Q output of the FF29 is logic "1", it is considered morning, and when the logic is "0-1", it is considered afternoon.
The frequency-divided signal is also sent to the AND circuit 30 or the AND circuit 3
2, and the other ANDa paths may be supplied with divided signals of other frequencies.

In this way, when the plate 5 is divided into 12 parts (shown in the first diagram), 1
FF2 is activated by a switch 27 that is turned on once every time it rotates.
Since the Q output of 9 is changed, it is difficult to tell whether the time displayed on the hour plate 5 of the 12-hour display is AM or PM using the crown 2.
You can tell by the identification sound that occurs when you rotate the machine.

FIG. 4 is a circuit diagram showing a second embodiment of the separate circuit in FIG. 2, and reference numeral 34 is a switch similar to the switch 27 in FIG. 3.

The switch signal obtained by this switch 34 is supplied to the clock terminal CL of the FF 38 via the impark 35.

The Q output of the FF 36 is supplied to a two-man powered AND circuit 37, which has one input terminal supplied with a third frequency-divided signal in the audible range from the frequency divider circuit 10 (second diagram).

The Q output of F''F36 is the fourth
It is supplied to the two-man-operated AND circuit 38 together with the frequency-divided signal.

Each output of the AND circuits 37 and 38 is connected to the two-man OR circuit 3.
9, the output of which is supplied to a two-man OR circuit 42 via a switch 40 which operates similarly to switch 31 shown in FIG.

The fourth D-divided signal supplied to the AND circuit 33 is sent to the three-man AND circuit 41 together with the fifth frequency-divided signal of relatively low frequency.
supplied to

The remaining input terminal of the AND circuit 41 is supplied with the detection signal from the coincidence circuit 19 (shown in the second diagram), and its output is supplied to the OR circuit 42 .

The output of the OR circuit 42 is supplied to the alarm drive circuit 25 (shown in the second figure) as an alarm signal and an identification signal.

Therefore, if we assume that the time is in the afternoon when the Q output of FF 36 is logic [1], similar to the Q output of FF 29 in FIG. If the Q output of the FF 36 is logic "1", the third frequency-divided signal is output from the OR circuit 42 as an identification signal.

Further, when the Q output of the FF 36 is the moon, the fourth frequency division signal is outputted from the OR circuit 42 as a time zone identification signal by rotating the crown 2 in the right direction.

Furthermore, when the alarm generation time comes, the detection signal becomes AN
The fourth frequency-divided signal is supplied to the D circuit 41, modulated by the fifth frequency-divided signal, and output as an alarm signal via the OR circuit 42.

In this way, by rotating the time plate 5 (first diagram) once, the output changes depending on the Q and Q outputs of FF'36, and when the crown 2 is rotated, a signal with different sounds is output as an alarm signal. Therefore, the time plate 5 (
The numerical display can be enlarged by using the numerals (as shown in Figure 1), and the time zones of morning and afternoon can be distinguished by the difference in sound 1].

In addition, in FIG. 4, as well as the circuit shown in FIG.
It will be easily understood that it is also possible to change or reverse the logical values of the frequency-divided signal or the Q and Q outputs of the FF 36.

FIG. 5 is a circuit diagram showing a third embodiment of the control circuit shown in FIG. 2, and reference numeral 43 indicates the switch 27 in FIG.
and a switch similar to switch 34 in FIG.

A switch signal obtained by this switch 43 is supplied to the clock terminal CL of the FF 45 via an inverter 44.

The calculated power of the FF45 is applied to the -power input terminal by the frequency dividing circuit 10 (
A sixth frequency-divided signal in the audible range is supplied from 2
LQ calculation power frequency dividing circuit 10 supplied to the human-powered AND circuit 46
(2nd diagram) 7th frequency divided signal (audible range) supplied from
The signal is also supplied to a two-man-operated AND circuit 47.

The outputs of each of the AND circuits 46, 47 are fed to a two-person OR circuit 48 whose outputs are connected via a switch 49 similar to switch 31 shown in FIG. 3 and switch 40 shown in FIG. The signal is supplied to a two-man powered OR circuit 51, and is also supplied to one input terminal of a three-man powered AND circuit 50.

The other input terminal of the AND circuit 50 is supplied with an eighth frequency-divided signal having a relatively low frequency and a detection signal from the coincidence circuit 19 (shown in the second diagram), and its output is supplied to an OR circuit 51. Ru.

The output of the OR circuit 51 is supplied to the alarm drive circuit 25 (shown in the second figure) as an alarm signal and an identification signal.

Therefore, just like the example shown in Figures 3 and 4, when the calculation power of FF45 is logic "1", the dial 3
Assuming that the time displayed on the window 4 (first illustration) is in the afternoon, when the crown 2 (first illustration) is rotated clockwise, if the calculation power of the FF 45 is logic "1", then the 6 is output from the OR circuit 51 as an identification signal, allowing the user to know that the time displayed on the window 4 (first illustration) of the dial 3 is in the afternoon.

Also, when the calculation power of the FF 45 is logical "moon", by rotating the crown 2 (first diagram) in the right direction, the OR circuit 51 outputs the seventh frequency division signal and identification signal, indicating that it is morning. can be known.

When the alarm generation time comes, a detection signal is output from the matching circuit 19 (shown in the second diagram). At this time, if the alarm generation time is set in the morning, the calculation output of the FF 45 is logic "1". Therefore, the seventh frequency-divided signal is output as an alarm signal, and if the set time is in the afternoon, the sixth frequency-divided signal is output as an alarm signal.

That is, the sound that is generated when setting the alarm generation time is also generated at the set time.

In this way, it has a switch 43 that is turned on once by rotating the time plate 5 (first illustration) once, and the Q and calculation power of the FF 45 change depending on the switch signal.
Since different identification sounds are generated when setting the alarm occurrence time according to the output change, it is recommended to use a 12-hour time plate 5 (shown in the first diagram) with large display characters to make the display easier to read. In addition, when setting the alarm occurrence time, the alarm occurrence time to be set is
It is easy to determine whether it is afternoon or not based on the identification sound that is generated.

Although the details of the electronic alarm clock according to the present invention have been explained above based on the illustrated embodiments, the present invention is not limited to the illustrated embodiments, and various changes and improvements can be made. be.

For example, switch 43°4 in FIGS. 3 to 5
0.49 can also be changed to a transmission gate controlled by a switch signal obtained by switch 21 shown in FIG.

Further, in the embodiment, the time slots to be distinguished are morning and afternoon, but it is also possible to provide a plurality of switches on the time plate 5 and set two or more time slots.

Note that in this case, it is necessary to change the control circuit.

As described above, the alarm electronic clock according to the present invention has a display section that displays the set time for 12 hours in response to the operation of the screen inch that sets the alarm occurrence time, and a window section that corresponds to the display section. Equipped with a control circuit that controls the generation of an identification sound to identify the time zone when setting the alarm occurrence time, depending on the time zone of the alarm occurrence time, so the display number that indicates the alarm occurrence time can be changed to a 24-hour display. It can be made sufficiently large in comparison, it can be easily read, and it can be used to easily identify whether the alarm occurred in the morning or in the afternoon. This can be achieved and has great effects in use.
