Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm timepiece, and more particularly to an alarm timepiece which has a 12-hour reference contact point and outputs an alarm by validating a reference contact point signal every 24 hours.

[0002]

2. Description of the Related Art In a conventional alarm clock, a reference contact is turned on every 12 hours, and even if the wake-up time on the next day is the same as today, the alarm set is always operated by a switch. The alarm was not set. In order to eliminate such annoyance, it was considered to improve the alarm clock having a 12-hour reference contact point so that an alarm is output every 24 hours. For example, the actual Kaisho 61-32
Japanese Laid-Open Patent Publication No. 1993-134996 and Japanese Laid-Open Patent Publication No. 63-134996, which uses an arbitrary timer from 13 hours to 23 hours to block the reference contact signal once.
2 by reversing according to the reference contact signal as in the 6083 publication
A four-hour alarm clock has been proposed, and the alarm set for the next day is automatically made only by turning off the alarm. Further, there is a display for indicating whether the reference contact is valid or invalid according to the output of a binary counter for inputting the operation of the reference contact as disclosed in Japanese Utility Model Laid-Open No. 63-12793.

[0003]

However, if the following criteria are valid, the above display is a blinking display in order to reduce current consumption even though the lighting element is lighted by the notification circuit.
However, since the blinking operation is performed for 12 hours even in this case, the current is still wasted. The present invention has been made in view of the above problems, and an object thereof is to prevent useless current consumption by notifying when the user wants to know. Further, this is to effectively notify information without increasing the number of operation switches.

[0004]

In order to achieve the above-mentioned object, the present invention provides an alarm clock having a squeaking switch for setting and non-setting an alarm and turning on a standard contact every 12 hours. , A reference control circuit for alternately enabling and disabling the reference signal from the reference contact, a stop switch for stopping the alarm output, and holding the signal from the stop switch and generating the reference signal or the reference control A latch circuit that is reset in response to the inversion of the output signal from the circuit, an alarm circuit that controls an alarm output in response to a signal from the sound stop switch, the reference control circuit, and the latch circuit, and the reference control circuit Input the output signal of and display whether the alarm is output by the next reference contact signal in response to the signal from the stop switch. Characterized by providing a knowledge circuit. Further, the notification circuit may change the content of notification depending on the state of the stop switch.

[0005]

The operation signal of the stop switch causes the latch circuit to store and hold this operation signal. Therefore, when an alarm is output, the output from the latch circuit stops the alarm through the alarm circuit and invalidates the next reference signal. Is displayed, and when the operation signal is generated when the alarm output is not made, the next valid or invalid of the standard contact is displayed according to the output of the standard control circuit. At this time, although the operation signal is stored and held in the latch circuit, it is reset when the reference contact is generated, so there is no problem in alarm generation. Therefore, each time the stop switch is operated, it is possible to display whether the signal at the next reference contact is valid or invalid, and the latch circuit is reset each time the signal from the reference contact is input, so a reliable alarm is issued. Can be stopped and there is no need to provide a confirmation switch, and it can also be used as a stop switch. Further, depending on the state of the stop switch, it is possible to inform whether or not an alarm output is generated at the next set time, whether an alarm is set, or that the stop switch is operated.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit block diagram of an alarm clock according to the present invention. Reference numeral 4 is a reference contact, which is incorporated in the timepiece train wheel and is turned on for a predetermined time (15 to 40 minutes) from the set time to output the reference signal. 6 is a stop switch, and 8 is a sound stop switch, which has the same function as a conventional alarm set / non-set switch, and is an alarm output control switch. 1
Reference numeral 0 is a reference control circuit which is composed of a binary counter and outputs a valid or invalid signal indicating whether or not the output signal state is inverted by the input signal from the reference contact 4 and an alarm is output by the next reference signal. However, in a normal use state with the alarm stop switch 8 in the alarm set state, it serves as a 24-hour guide mechanism. Further, since the alarm is set to be output by the following reference signal by the alarm setting operation of the stop switch 8, the stop switch 8 can be used as a conventional 12-hour reference clock. Reference numeral 12 is a pulse generating circuit, which is a stop switch 6
A single pulse is output every time is operated. Reference numeral 14 denotes a latch circuit, which stores and outputs the operation of the stop switch 6 and is reset in response to the signal generation from the reference contact 4. Reference numeral 20 denotes an alarm circuit, which is an alarm control circuit 2
2. The sound generation circuit 24 and the speaker 26 are provided, and the signals from the reference control circuit 10, the latch circuit 14, and the sound stop switch 8 are input so that the sound stop switch 8 is in the alarm set state and the reference control circuit 10 outputs. An alarm is output in response to the generation of a reference signal when the effective signal of
The alarm output is stopped by the operation signal of the stop switch 6 from the latch circuit 14.

Next, the operation will be described. At the time of the first alarm setting, when the time is set to the wake-up time and the alarm stop state is set by the sound stop switch 8, the reference control circuit 10 outputs a valid signal that validates the next reference signal, and the alarm is activated within 12 hours. Is output. At the set time, the reference contact 4 is turned on, the output signal of the reference control circuit 10 is inverted into an invalid signal, and the latch circuit 14 is reset in synchronization with the rising of the reference signal. The alarm control circuit outputs an alarm in response to the reset output of the latch circuit 14 and the invalid signal of the reference control circuit 10. When an alarm is output, the output of the latch circuit 14 is inverted by the stop switch 6 and the alarm control circuit 22 stops the alarm output. In accordance with the operation of the stop switch 6, the notification circuit 30 displays, in response to the invalid signal of the reference control circuit, that the alarm is not output by the next reference signal. After that, the reference control circuit 10 inverts the output in response to the generation of the reference signal.
It will operate as an alarm clock for 4 hours. The output of the latch circuit 14 is reset by the generation of the next reference signal. At this time, the alarm control circuit 22 outputs a valid signal as the output signal of the reference control circuit 10, and no alarm is output. When confirming whether or not an alarm is output before going to bed, etc., by operating the stop switch 6, the notification circuit 30 causes the display element 32 to light up if the valid signal of the reference control circuit 10 is output. It indicates that an alarm output is generated by the operation of the next reference contact 4, and when the invalid signal is output, the display element 3
4 is lit to indicate that no alarm output will be generated by the next operation of the reference contact 4. Since the above operation is repeated and the alarm output is automatically generated 24 hours later, it is not necessary to set the alarm of the stop switch 8 each time.

Since the latch circuit 14, which is a feature of the present invention, is reset by the generation of the reference signal, the fact that the stop switch 6 has been operated can be surely stored and output at the time of alarm output, and the alarm can be stopped. For example, when the latch is released by the timer, there is a problem that the alarm output is not generated even if the reference signal is generated from the reference contact from the operation of the stop switch to the time up. Also,
Even if it is operated before the reference signal is generated, it will be reset when the reference signal is generated, so it will not affect the alarm output, and the operation signal can be accepted at any time to ensure whether or not an alarm is output. It is something you can know.

In FIG. 1, the signal of the stop switch 8 is input to the standard control circuit 10 so that an alarm output is generated by the next standard signal immediately after the switch 8 is set. A switch may be separately provided and the output of the reference control circuit 10 may be inverted every time the switch is operated. Further, the alarm circuit 30 has a sound stop switch 8
Signal is input and the display is not displayed when the switch 8 is in the non-set state, it may be displayed regardless of the switch signal, or the notification circuit 30 may be a voice notification. It is possible to notify that the stop switch 8 is not set or that the stop switch has been operated. It is possible to input the reference signal of the reference contact 4 to the alarm control circuit 22 or add an auto stop mechanism by a timer so that the alarm is not output for a predetermined time or longer as in the conventional case.

Further, when the stop switch 6 is used as various sensors to notify when a signal from the outside is detected, it is possible to provide an alarm clock with more taste. For example, an infrared sensor or an illuminance sensor can be notified when there is a change, and it can be notified whether an alarm sounds or not, and it can also be used as a targeting game by inputting a signal from an external device.

[0011]

As described above, according to the present invention, the latch circuit for latching the signal of the stop switch for stopping the alarm output is reset with the generation of the reference signal. It is possible to stop the alarm and to activate the notification circuit regardless of the output of the alarm. It can notify that the switch has operated and notify the necessary information by changing the notification sound according to various switch states. This makes it possible to add a taste as a game.
