Description

[Detailed explanation of the idea] The present invention relates to an electronic time signal clock.

2. Description of the Related Art Conventionally, some electronic watches that generate a time signal sound every hour on the hour generate a sound when correcting the contents of a memory circuit for the hour.

However, according to this, after the correction is completed,
I was not able to confirm whether or not the correction had been made accurately, which left me feeling uneasy.

Therefore, the present invention provides an electronic timepiece that can notify and confirm the corrected contents of the memory circuit after the correction is completed.

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 generating circuit for time reporting, 5 is a first signal generating circuit for time reporting, and 6 and 7 are a control signal generating circuit and a second signal generating circuit for correction reporting, respectively. Reference numeral 8 designates an hour storage circuit, 9 a time reporting circuit, and 10 a coincidence circuit. 11, 12, and 13 are flip-flop circuits. 14 is a counter, 15...21 is a gate circuit, and 22 is an inverter. 23...26 is a differentiation circuit, 27 is a delay circuit, 29 is a sounding device, 3
0 is a correction switch, 31 is a chattering prevention circuit, and 32 is a resistor.

Next, the operation will be explained. At the hour, an output is generated from the detection device 1, the flip-flop circuit 11 is set, and the gate circuit 15 is opened by the output Q, and the control signal generation circuit 4 is operated. In this example, the control signal generation circuit 4 is set to generate a control signal with a period of 1 second, and this is supplied to the signal generation circuit 5 via the gate circuit 15 to generate a time signal and generate the sound generation device 29. A time signal sound is generated. On the other hand, the above control signal is the gate circuit 1
6 and is supplied to a counting circuit 9, where the number of time reports is counted. When the content of this count matches the content of the memory circuit 8, an output is generated from the coincidence circuit 10, the flip-flop circuit 11 is reset, the time signal stops, and the content of the memory circuit 8 is read out via the gate circuits 18 and 19. Proceed. Further, the output of the matching circuit 10 is differentiated by the differentiating circuit 25, and the counting circuit 9 is reset.

The above operation is performed every hour on the hour to signal the time.

Next, the operation of correcting the contents of the memory circuit 8 will be explained. It is assumed that in the initial state, the flip-flop circuit 12 is reset, and its output opens the gate circuits 18 and 21, and the counter 14 is held in the reset state. When the correction switch 30 is then closed, the differential pulse is supplied to the memory circuit 8 via the gate circuit 21 and reset. On the other hand, the differential pulse is slightly delayed by the delay circuit 27, and the flip-flop circuit 12 is set and the content of the memory circuit 8 is set to 1. By setting the flip-flop circuit 12, the counter 1
When the reset of 4 is released, the gate circuit 1
8, 21 closes. The counter 14 receives the pulse from the frequency divider 3 and is set to produce an output when, for example, 3 seconds have elapsed.

Therefore, when the correction switch 30 is closed again within three seconds, the content of the memory circuit 8 is incremented by one by the differential pulse, and the counter 14 is reset.

That is, in normal correction, the operation interval of the correction switch 30 does not exceed 3 seconds, so no output is generated from the counter 14 during the correction. When three seconds have passed since the final operation of the correction switch is completed, an output is generated from the counter 14, and the flip-flop circuit 13 is set by the differential pulse. The gate circuit 17 is opened by the output Q, the control signal generating circuit 6 is operated, and the control signal passes through the gate circuit 17. The generation cycle of this control signal is set to 0.5 seconds in this example, and as a result, the signal generation circuit 7 generates a correction notification signal, and the sounding device 29 generates a correction notification sound different from the time signal. Occur. This notification sound is used to confirm the stored contents after correction, and in order to shorten the time required for this confirmation, the generation interval is set to 1/2 of the time notification sound. On the other hand, the above control signal is transmitted to the gate circuit 16.
The signal is supplied to the counting circuit 9 via the alarm circuit 9, and the number of generated notification sounds is counted. When the counted contents match the stored contents of the memory circuit 8, an output is generated from the matching circuit 10, the flip-flop circuit 13 is reset, the notification sound stops, and the counting circuit 9 is reset. While the above coincidence output is being generated, the gate circuit 18
is closed, the contents of the memory circuit 8 are not incremented, and when the coincidence output is stopped by the above-mentioned reset of the counting circuit 9, the inverter 22 and the differentiating circuit 2
6, the flip-flop circuit 12 is reset and returns to its initial state.

Incidentally, in the above embodiment, the time signal sound and the correction notification sound are made different, but they may be made common in order to simplify the circuit configuration. For example, as shown in FIG. 2, the flip-flop circuit 11 is set based on the output of the counter 14 after the correction is completed, and the same sound as the hourly sound is generated by the number of contents stored in the memory circuit 8 in exactly the same way as when the hour is announced. occurs.

In the above embodiment, the contents of the memory circuit are incremented one by one each time the correction switch is operated, but the invention is not limited to this, and correction can be made by generating correction pulses at a constant cycle while the correction switch is pressed. You may also do this.

In either case, a sound may be generated in conjunction with the operation of the correction switch, and a notification sound for confirmation may be generated after the correction is completed.

Further, the time from the end of the correction to the generation of the notification sound is not limited to three seconds as in the above embodiment, but may be set as appropriate as necessary.

Further, the notification of time and correction is not limited to sound, and may be performed by light.

As described in detail above, according to the present invention, after the contents of the storage circuit at the hour are corrected, the corrected storage contents are notified, so that it can be confirmed whether or not the correction has been performed correctly.
