Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a clock device that is installed on a street or the like and notifies the time by operating a puppet device or the like at a fixed time, for example, on the hour.

(Prior art) Conventionally, as shown in Utility Model Application Publication No. 49-51267,
For example, a so-called karakuri clock has been proposed, which informs nearby people of the time by activating a puppet device or automatic musical instrument attached to the hour or half past hour.
They are being installed on the streets.

(Problems to be Solved by the Invention) Since this type of mechanical clock is on the street, it is necessary to stop the time-reporting operation on rainy or windy days to prevent danger. This can be done by attaching an anemometer or rain gauge to the watch and stopping the watch when the wind speed or rainfall exceeds a certain value, but a. Wind speed or rainfall cannot be measured instantly.

b. If the time signal operation is stopped without any prior notice,
I think the people who gather to see this (starting about 10 minutes in advance) are out of order, and if they've been waiting in anticipation for minutes and nothing happens, they'll feel uncomfortable and watch the clock. This will greatly damage the image of the installer.

There were problems such as.

(Means for Solving the Problems) The present invention is characterized in that the suspension of the time reporting operation to prevent such danger is notified at and before the scheduled time. To this end, the present invention includes an on-time detector that detects a certain amount of time before the scheduled time, an alarm sensor that operates based on a signal from the on-time detector, and an alarm sensor that starts operation based on the detection signal from the on-time detector. a first gate that allows the output signal from the timer to pass only when a detection signal is generated from the alarm sensor; and an output signal generation from the first gate. The present invention is characterized in that it includes an alarm device that performs an alarm operation for a certain period of time starting from the hour, and a second gate that prevents an operation signal from being input to the time alarm device in response to an output signal from the first gate.

(Embodiment) FIG. 1 is a block diagram of a timepiece according to an embodiment of the present invention, and FIG. 2 is a waveform diagram showing its signal form.

In FIG. 1, a master clock 2 measures the time and supplies a driving pulse signal at a constant cycle, for example, every minute, to a large device clock 4 installed on the street. This pulse causes the device clock 4 to drive the hands and display the time. When the time measured by the master clock 2 reaches the hour, the hour detector 6 detects this and outputs a detection signal to the time signal device 8. The time signal device 8 is composed of an automatic performance device or a puppet device, and is configured to start its operation when a detection signal is input.

The master clock 2 is also provided with an on-the-hour detector 10 that detects a fixed time before the hour, which in this embodiment is 47 minutes past the hour, that is, 13 minutes before the hour. This hourly detector 1
With the detection signal A of 0, the wind speed sensor 14 and rain sensor 16 as the alarm sensor 12 start detection operations. These wind speeds and rainfall amounts require a certain amount of measurement time, and the measurement results appear after a certain period of time. If the amount is above a certain level, a detection signal is output.

The detection signal from the hourly detector 10 also enables the six minute timer 18. For this reason, the timer 18 outputs the signal B to the first gate 20 when 6 minutes have elapsed since the timer start time (13 minutes before the hour). The first gate 20 has an alarm sensor 12
The signal B from the 6-minute timer 18 is input to the alarm device 22 only when the detection signal from the 6-minute timer 18 is generated, that is, only when the wind speed and rainfall are measured to be above a certain level. This signal B is input to the set input S of the FF 24 and raises its output signal C to H level. This signal C is delayed by a certain period of time (about 45 seconds in the embodiment) by a delay circuit 26 and sent to the warning device 2.
8. The warning device 28 receives this signal D and, for example, plays "Ping Pong" (BGM about 10
Ping Pone, we apologize for the inconvenience, but the wind and rain automatic stop device has been activated, so we have to cancel the performance. please note that. (BGM approximately 30 seconds)" warning sound is repeated. This operation continues until the output of the 3 minute timer 30, which is activated by the output signal B of the 6 minute timer 18, is supplied to the reset input R of the FF 24.

This operation is performed again six minutes after the first warning, that is, when signal B is output from the six-minute timer 18 one minute before the hour. A warning sound will start 15 seconds before the hour.

6 minute timer 18 after passing through the first gate 20
The signal B is also input to the set input S of the FF 34 of the second gate 32. As a result, the output of the FF 34 becomes L level, and the connected AND gate 36 is closed. As a result, the detection signal from the hour detector 6 is prevented from being input to the time signal device 8,
Normally, the time signal operation on the hour is not performed. Thereafter, a signal from the after-hours detector 38, which detects that a certain period of time has passed since the hour by the master clock 2, is input to the reset input R of the FF 34.
The output returns to H level again in preparation for the next hour.

In the present embodiment, the explanation has been given of a case in which the time signal operation is performed every hour, but it can also be applied to a clock that is performed every half hour, and the warning device 2
8 may be a display device.

(Effects of the invention) As described above, according to the invention, when the time signal operation is stopped due to deterioration of the external environment such as wind and rain, the warning is issued when onlookers begin to gather and just before the scheduled time, so it may be mistaken for a malfunction. , it will not make the viewer feel uncomfortable, and it will not damage the image or credibility of the clock installer.
