Abstract

PURPOSE:To inhibit time-signal in midnight and perform specific time-signal before and after it and in a succeeding time zone by discriminating time zones in a day, and generating three kinds of time-signal control signal according to the time zones and controlling the inhibition of the time-signal. CONSTITUTION:A discriminating circuit 9 discriminates on the time zone in a day according to count outputs of a counter 6 which counts outputs of 15-min intervals from a frequency divider 5 and a 24-scale hour counter 8 and outputs three kinds of time-casting control signal to control the closure of gates 9-21. Consequently, the cutoff of time-signal signals of every 15, 30, and 45min from monostable multivibrator 15-17 and a regular time-signal signal from a monostable multivibrator 14 is controlled. The time-signal is not performed in midtime from AM1:00 to AM3:45, and the regular time is struck in time zones before and after it, i.e. from PM10:00 to AM0:45 and from AM4:00 to AM6:45; and the time- signal is performed at intervals of 30min including the regular time from PM7:00 to PM9:45 and from AM7:00 to AM9:45, and at intervals of 15min including the regular time in other time zones.

Description

[Detailed description of the invention] The present invention relates to a timepiece.

Conventionally, there are clocks that sound a chime on the hour and every 15 minutes after the hour, but since chimes sounding every 15 minutes at night can be annoying, some clocks are equipped with a chime switch to stop the chime at night. . However, according to this method, the operation to stop and release the sound must be performed every day, which is extremely troublesome.

Therefore, the present invention disables the sound signal during the time when the liquid is in the liquid, and only makes the sound on the hour during the time before and after that, and furthermore, during the time before and after that, the sound is on the hour and 30 minutes. To provide a time signal clock which makes a sound only at times.

An embodiment of the present invention will be described below based on the drawings. 1st
In the figure, 1 is an oscillator, 2 is a frequency divider, 3 is a drive circuit for motor μ, and motor 4 is for stepping a time display hand (not shown). Reference numeral 5 denotes a branching unit which produces an output every 15 minutes, which is counted by a quaternary counter 6. 7 is a decoder, and its output terminal T15. Outputs are generated from T0n and T45 at the 15th, 30th, and 45th minutes of every hour, respectively.

8 is a 24-decimal time counter, 9 is a specific time zone discrimination circuit, and its output terminal 9α outputs signals from 1:00 a.m. to 3:00 a.m.
A discrimination output (alarm control signal) for the first time period up to 5 minutes is generated, and output terminals 9h and 9c output signals for the second time period before and after the first time period, that is, from 10 p.m. to 12 p.m. Discrimination outputs from 4:45 am and 4:00 am to 6:45 am are generated. Furthermore, the terminals 9d and 9a are respectively connected to the sixth time period, that is, from 7:00 p.m. to 9:04 p.m.
5 minutes and from 7:00 AM to 9:45 AM. 1o is a memory circuit consisting of ROM;
The melody data for the chime performed every 5 minutes and the melody data for the time stamp are stored. 11 is an address counter.

A read control circuit consisting of an address designating ROM, etc. reads out melody data for chimes at the hour, 15 minutes, 30 minutes, and 45 minutes, as well as melody data for striking the hour on the hour. 12 is a D-A conversion circuit, ``'' is a sound generating device, 14 to 17 are one-shot pulse generators, and 18 to 24 are gate circuits. Gate circuit 2
3.degree. 24 and the discrimination circuit 9 constitute a discrimination control circuit. 25 is a switch that closes just before the hour.

Next, the operation will be explained. During the fourth time period from 10 a.m. to 6:45 p.m., each output of the discrimination circuit 9 is t.
o Since it is held at Or+, gate circuits 19 to 22
is open. Therefore, at 10:15 am, for example, a pulse is generated from the one-shot pulse generator 15 by the output from the terminal T15 of the decoder 7, and this pulse is supplied to the read control circuit 11 via the gate circuit 192. As a result, the read control circuit 11 specifies the address of the chime melody data for the 15th minute, and this is sequentially read out from the storage circuit 10. This melody data is converted into a musical tone signal by the D-A converter circuit 12, and the sound generating device 1
A chime sound occurs from 3. At 10:60 a.m., a pulse is generated from the one-shot pulse generator 16, which specifies the address of the chime melody data for 30 minutes, which is read out from the memory circuit 1o to generate a chime sound.

At 10:45 a.m., a pulse is generated from the one-shot pulse generator 17, which specifies the address of the chime melody data at 10:45 a.m., and this is read out from the memory circuit 1o to generate a chime sound.

Then, a little before 11:00 a.m., the switch 25 is closed and the gate circuit 18 is opened, and a pulse is generated from the one-shot pulse generator 14 by the 12 signals from the divider 5 at 11:00 a.m. The counter 8 is incremented by this pulse and counts 11 o'clock. On the other hand, the above-mentioned pulse is supplied to the readout control output 11, thereby specifying the address of the chime melody data on the hour, which is read out from the memory circuit 1o to generate a chime sound. When the generation of the chime ends, the readout control circuit 11 specifies the address of the melody data for the time beat, and this is read out repeatedly to produce the time beat sound. When the number of occurrences of the time-beating sound matches the contents of the counter 8, the reading of the data is completed and the time-beating is completed.

During the fourth time period, the alarm is made every 15 minutes as described above.

and the third time period, i.e. from 7pm to 9:04pm.
5 minutes and from 7:00 a.m. to 9:45 a.m., the terminals 9'tl and 9t of the discrimination circuit 9 become tl1#, and the gate circuit 19.21 is closed by the alarm control signal from the gate circuit 24. to be accomplished. Therefore, pulses at 15 minutes and 45 minutes from one-shot pulse generation H15 and H17 are prohibited. Therefore, the 15-minute and 45-minute beeps are prohibited, and only the hourly and 30-minute beeps are made.

Also, during the second time period from 10:00 p.m. to 12:45 a.m. and from 4:00 a.m. to 6:45 a.m., the discrimination circuit 9
The terminals 9b and 9C become "1", an alarm control signal is generated from the gate circuit 23, and the gate circuits 19, 20, and 21 are closed. Therefore, the 15-minute, 30-minute, and 45-minute alarms are prohibited during this time period, and the alarm is only made on the hour.

During the first time period from 1:00 a.m. to 6:45 a.m., the terminal 9α becomes '1'' and all gate circuits 19 to 22 are closed by this alarm control signal. All alarms are prohibited.

FIG. 2 shows a configuration in which a volume adjustment circuit 26 is added to the configuration shown in FIG. With this, the fourth. 6th degree 2nd. The volume of the alarm sound in the first time period is decreased in this order. In other words, the volume is set to the minimum during the first time period, which is midnight, and the volume is set to the maximum during the fourth time period, which is daytime.

Note that during the second time period, the hour chime may also be prohibited and only the hour chime may be performed. Furthermore, the chime on the hour may also be prohibited during the sixth time period.

Furthermore, each time period is not limited to the above, and may be set as appropriate.

Also, a memory circuit 10 that generates a chime and a ticking sound.
Read control circuit 11. The sound alarm device consisting of the D-A converter circuit 12 etc. is not limited to the one having such a configuration.
It can be applied to anything that makes a sound every minute.

As described above, according to the present invention, all alarm sounds are prohibited during times such as midnight, so sleep is not disturbed.
During the hours before and after the hour, such as during the night, only the hour alarm is emitted, so it is less likely to disturb your sleep, and moreover, if you are awake, you can hear the hourly time. Furthermore, in the evening
During times such as early morning, the alarm is made on the hour and at the 30th minute, so you can hear the time every 30 minutes without being bothersome, and during the daytime, etc., the alarm is made every 15 minutes. 6, so you can hear the time every 15 minutes.
