Description

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

Conventionally, watches with a time signal function that stop the time signal at night have had a large structure because the stop time has been set using a cam or the like linked to a car 24 hours a day. In addition, a display board connected to the car 24 hours a day was used to distinguish between AM and PM, and when setting the time, the user had to turn the hand to set AM and PM, which was cumbersome.

Therefore, the present invention provides an electronic time signal clock that uses an electronic configuration to notify the time and stop it at night.
This eliminates the drawbacks of the conventional method.

An embodiment of the present invention will be described below based on the drawings. In FIG. 1, 1 is an hour detecting device, 2 is a crystal oscillator, and 3 is a frequency divider. 4 is a control signal generation circuit; 5 is a signal generation circuit that generates a time signal;
6 is a sounding device. 7 is a decimal hour clock circuit, 8 is a time counting circuit, and 9 is a coincidence circuit. 10 is a storage circuit, and 11 is a comparison circuit. 1
2, 13, and 14 are flip-flop circuits, and 15 is a counter. 16 and 17 are gate circuits, 18
is a manual switch for setting the stop time. 19,
20 are AM and PM setting switches, respectively;
21 is a stop release switch, and 22...25 is a resistor.

Next, the operation will be explained. First, we will discuss the time signal operation. Note that the flip-flop circuit 12,
14 has been reset, the gate circuit 17 is open, and the clock circuit 7 is assumed to be counting the next hour on the hour. When an output is generated from the detection device 1 on the hour, the flip-flop circuit 12 is set, and its output Q operates the control signal generation circuit 4 and opens the gate circuit 16. In this example, the control signal generating circuit 4 is set to generate a control signal with a period of 1 second, and this is supplied to the counting circuit 8 and the signal generating circuit 5 via the gate circuit 16. A time signal is generated from the signal generating circuit 5, and is supplied to the sounding device 6 via the gate circuit 17 to generate a time signal. On the other hand, the counting circuit 8 receives the control signal and counts the number of time reports. When the counted contents match the timed contents of the clock circuit 7, an output is generated from the coincidence circuit 9, the flip-flop circuit 12 is reset, and the time reporting ends. On the other hand, the above output from the matching circuit 9 is
At the same time, the contents of the clock circuit 7 are advanced by one.

Time reporting is performed in the manner described above.

Next, a description will be given of the operation of stopping the alarm at night or the like. The clock circuit 7 is incremented by one at every hour on the hour as described above, and the flip-flop circuit 13 is triggered by the output every 12 hours, and the output Q is set to "1" and "0" in the morning and afternoon, respectively. is maintained. When the desired time to stop the time reporting arrives, the switch 18 is closed and the contents of the clock circuit 7 and the output of the flip-flop circuit 13 are stored in the memory circuit 10. For example, if you want to stop the time signal after 10 o'clock, the clock circuit 9 measures 10 o'clock from the end of the 9 p.m. time signal until 10 p.m., and the flip-flop circuit 13
When the output Q of the switch is "0", the switch 18 is closed. As a result, 10:00 pm is stored in the memory circuit 10, an output is generated from the comparator circuit 11, and the flip-flop circuit 14 is set.
Therefore, the gate circuit 17 is closed, the time signal is cut off, and the time is no longer reported. On the other hand, the reset of the counter 15 is canceled by the output Q of the flip-flop circuit 14, and the counter 15 is reset to the coincidence circuit 9.
Timing of the time signal stop time is started by the output every hour on the hour. For example, the time measured by the counter 15 is 8
If you set it to the time, the output will occur after 8 hours.
Flip-flop circuit 14 is reset, gate circuit 17 is opened, and a time signal is made at each subsequent hour on the hour.

When the time signal of 9 p.m. ends again and the clock circuit 7 measures 10 o'clock, an output is generated from the comparator circuit 11, and the time signal stops until 8 hours later.

To cancel the stoppage of the alarm, the gate circuit 17 may be opened by closing the switch 21.

As detailed above, according to the present invention, a manual switch is operated at a desired time to memorize the time,
Since the time signal is stopped for a certain period of time from that time every day, the time signal can be stopped at any time by simply installing one external switch, making it extremely simple in terms of configuration. can.
