Abstract

PURPOSE:To prevent the disturbance of sleep and to make time signal operation easy by inhibiting the signal at night. CONSTITUTION:In the time band from 7 a.m. to 8:45 p.m., each output of a discrimination circuit 9 is kept at ''0'', outputs from one-shot multivibrators 15- 17 at 15min, 30min and 45min and an output from an one-shot multivibrator 14 at noon are applied to a reading control circuit 11, so that the circuit 11 specifies a prescribed address in a storage circuit 10 every 15min and a chime melody data are read out from the circuit 10 and signalled from a speaker 13. In the time bands from 9 a.m. to 10:45 p.m. and from 5 a.m. to 6:45 p.m., only the noon is signalled. In the time band from 11 p.m. to 4:45 a.m., the output 9a of the discrimination circuit is turned to ''1'' and all signals are inhibited.

Description

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

Conventionally, there was a time reduction system in which a chime sounded on the hour and every 15 minutes after the hour, but it would be annoying if the chime sounded every 15 minutes at night. There is something to do.

However, according to this, it is extremely troublesome to operate the 4rF Nikari city and stop the f/jib (/H).

Therefore, the present invention prohibits the sounding of l- during times such as nighttime,
The purpose of this invention is to provide a time signal clock that is designed to emit a sound on the hour during time periods such as before and after that time. An embodiment of the present invention will be described below based on the drawings. 1st
In the figure, 1 is an oscillator and a 2-digit frequency divider.

The drive circuit of the 6-digit morph earth, the morph earth is the time display pointer (
(not shown). With a 5-digit frequency divider, 15
An output is produced every minute, which is incremented by a quaternary counter 6. 7 is a lever, whose output end is 1,000 T15
+ 30th and 45th Karage 15 per hour each
Output occurs at minutes, 30 minutes, and 45 minutes. 8 is a counter in 24 decimal notation, 9 is a specific time zone discrimination circuit, and its output terminal 9a outputs the first signal from 11 p.m. to 4:45 a.m.
A discrimination output (alarm control signal) is generated for the time period of , and output terminals 9b and 9C output the first time period of the second time period, that is, from 9:00 p.m. to 10:00 p.m. Discrimination outputs are generated at 1:45 a.m. and from 5:00 a.m. to 6:45 a.m. 10 is a memory circuit consisting of ROM, and every 15 minutes (
The melody data for the chime to be played and the melody data for the time stamp are stored. A readout control circuit consisting of an 11-digit address register, an address IH regular ROM, etc., indicates the hour.

The melody data for the chime at the 15th, 30th, and 45th minutes is read out, as well as the melody data for the hour strike at the hour.

12 is the D-A disaster circuit, 1'' is the sounding device, 14-17i
1': lr7 function generator, 18-23)/-to circuit-'rh. The nometer circuit 23 and the discrimination circuit 9π constitute a discrimination control circuit. 24il
'lt is a switch that closes one minute before the hour.

Finally, I would like to explain the operation. 7:00 a.m. to 8:04 p.m.
During the third time period up to 5 minutes, each output of the discrimination circuit 9 is ``0''.
Since 9Vc is maintained, gate circuits 19 to 22 are open. Therefore, at 7:15 a.m., for example, the output from the terminal T of the decoder 7 generates a pulse from the one-shot pulse generator 15, which is sent to the readout control circuit 11 via the gate circuit 19. Supplied.

As a result, the address of the chime melody in the read control circuit 111-115 is specified 101,
This is the memory circuit 10 to 11■ Primary station/personnel h,ru.

This melody data is converted into a gradation message by the D-A switching circuit 12. A chime sound is generated from the sound generating device 13. At 7:30 am, a pulse is generated from the one-shot pulse generator 16, which causes a 30 minute i'171> The address of the melody data of the chime is specified, and the chime sound is emitted from the r inert circuit 10, and the chime sound disappears at 7:45 a.m. ((Hawan shot pulse is generated) A pulse is generated from the device 17, which specifies the address of the melody data for the chime that will appear at the 45th minute.
A chime sound is generated from the Japanese circuit 10.

Then, a little before 8:00 a.m., the Nui Sochi 24 closes and the gate circuit 18 opens, and at 8:00 a.m., the one-shot pulse generator 14 receives a 1-minute signal from the frequency divider 5. Rusu is caused. This pulse f causes the counter 8 to step down by one step and count 8 o'clock. On the other hand, the above e pulse y is supplied to the Mf output 5 control circuit 11, and the address of the melody data of the chime at the hour is specified by kneading. The sound is generated +A0 When the generation of this chime is finished, the address of the melodic day for the hour is specified by the ut output control 1 circuit 11, and this is repeated 1.
．． It's reading A. There is a ticking sound. This nap :l
When the number of occurrences of 'J' sounds matches the contents of the counter 8, the reading of the tenth period data is completed and the time stamping is completed.

VC reports will be held every 5 minutes.

Terminals 9b and 9c of the discriminator circuit 9 are connected during the second hour of the IHj band from 9:00 a.m. to 10:45 p.m. and from 5:00 a.m. to 6:45 a.m. "1" The gate circuit 1 is activated by the alarm control signal from the toh gate circuit 23.
9 to 21 are closed. Therefore, the pulses from the one-shot soto pulse generators 15 to 17 at 15 minutes and 309.45 minutes are prohibited.

Therefore, the 15-minute, 30-minute, and 45-minute beeps are prohibited, and only the hourly beep is made.

Further, during the first time period from 11:00 pm to 4:45 am, the terminal 9a of the discrimination circuit 9 becomes //1'l(,(), and the gate circuits 19 to 22 are closed by this alarm control signal. However, it was on the hour at this time.

All 15 minute, 50 minute and 45 minute signals are prohibited.

It is also possible to prohibit the chime on the hour (7) and only make the hour chime sound.

It is not limited to 15 minutes, but it can also be used repeatedly in QIK.

All alarms are prohibited during the hours of 10 and 10, so it will not disturb your sleep, and during the hours before and after that. Since the hourly alarm sounds, you can aurally know the time for each furnace 1.
Obi (with a sound signal every 15 minutes), you can hear the time every 15 minutes, and also [Temple 11j]
By controlling the volume depending on the volume, it is possible to prevent noise from occurring at night.
