Abstract

PURPOSE:To prevent the setting of an alarm from being forgotten, by generating the message corresponding to the setting state of the alarm on the basis of the output detected by a human body sensor. CONSTITUTION:The start time and finish time of a specific time zone containing the time performing the setting operation of an usual alarm are inputted to a memory circuit 5 by an input means 4 to be stored thereon. The content of this circuit 5 and the clocking time of a clock circuit 1 are compared by a judge circuit 6 and, when a set time zone appears, output is generated from the circuit 6 to open gate circuits 20, 21. A human body sensor 7 detects the approach of a person and an one-shot circuit 8 receives the detection signal to generate a pulse. Herein, when a sound stop switch 15 is closed and an alarm is in a non-setting state, the pulse passes through the circuit 20 to be supplied to a sound synthesizer circuit 18 to output such message that the alarm is not set. When the switch is opened and the alarm is not set, the pulse passes through the circuit 21 to be supplied to the circuit 18 to issue such a massage that the alarm is set.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an alarm clock.

[Prior Art] In conventional alarm clocks, whether an alarm is set or not is determined by checking whether an alarm set button is pressed.

[Problems to be Solved by the Invention] With the above-mentioned devices, people often forget to set their alarms, resulting in them being late in the morning because the alarm does not go off, or missing important appointments.

The present invention aims to minimize the possibility of forgetting to set an alarm.

[Means for Solving the Problems] The present invention is provided with a notification unit that notifies an alarm set state when a human body is detected by a human body sensor during a specific time period.

[Example/Example] In the drawings, 1 is a clock circuit for measuring time, 2 is a display thereof, 3 is a means for setting a specific time period, input means 4 such as a numeric keypad, and a start time and an end time of the time period are shown. It consists of a memory circuit 5 that stores . Reference numeral 6 denotes a time zone determination circuit, which generates an output during the time zone set in the memory circuit 5.

7 is a human body sensor consisting of an infrared sensor etc. that detects the presence of a human body within a certain range; 8.9 is a one-shot circuit; 10
1 is a flip-flop circuit, and 11 is an alarm circuit.

12 is a gate circuit, 13 is a delay circuit, 14 is an alarm switch, and 15 is a ring stop switch. Reference numeral 16 denotes a notification means, which includes a memory circuit 17 storing messages, a speech synthesis circuit 18, a sound generating device 19, gate circuits 20, 21, and an inverter 23.

Next, the operation will be explained. First, use the input means 4' to input the time at which you normally set the alarm (generally,
The start time and end time of a specific time period including (time of bedtime) are manually stored in the memory circuit 5. The contents of the memory circuit 5 and the time measured by the clock circuit 1 are compared in the judgment circuit 6, and when the time period set above is reached, an output is generated from the judgment circuit 6 and the gate circuit 20.21 is opened. ' When a person approaches this timepiece device, it is detected by the human body sensor 7 , and one pulse is generated from the one-shot circuit 8 and supplied to the gate circuit 12 .

Assuming that the flip-flop circuit 10 is now reset and the gate circuit 12 is open, the pulse passes through it and is supplied to the gate circuits 20 and 21. On the other hand, the output of the anti-squeal switch 15 is supplied to the gate circuit 20, and the output of the anti-squeal switch 15 is inverted in level by an inverter 23 and supplied to the gate circuit 21. Therefore, when the ring stop switch 15 is closed and the alarm is in a non-set state, the pulse passes through the gate circuit 20 and is supplied to the voice synthesis circuit 18. At this time, a message indicating that the alarm has not been set, such as "Do I have to wake you up tomorrow?", is selected from the memory circuit 17 and is supplied to the speech synthesis circuit 18, where it is synthesized into speech and sent to the sound generation device. Announcement will be made from 19.

Further, when the ring stop switch 15 is open and an alarm is set, the pulse is supplied to the voice synthesis circuit 18 via the gate circuit 21. by this,
A message to the effect that an alarm has been set, such as a message such as "I'll wake you up tomorrow", is selected from the memory circuit 17 and supplied to the speech synthesis circuit 18 for speech synthesis, and then notified from the sound generation device 19.

By the way, the above-mentioned pulse that has passed through the gate circuit 20 or 21 is slightly delayed by the delay circuit 13 and resets the flip-flop circuit 10.

Therefore, the gate lff1 path 12 and the gate circuit 12 are closed until the alarm switch 14 is closed and the flip-flop circuit 10 is reset, and the above-mentioned notification is not performed.

If the current time or alarm time is used in a known clock that announces the alarm time by voice, when announcing that an alarm has been set, for example, the alarm time will be announced as "I'll wake you up at 11:00 tomorrow." may be notified.

[Effects of the Invention] According to the present invention, the set state of the alarm is notified when a human body is detected during a specific time period, so even if you forget to set the alarm, you can set it without any special operation. You can know when you forget to set it, and you can prevent forgetting to set it. Also, by arbitrarily setting a specific time period that suits your lifestyle, you can be sure to receive notifications when you go to bed.
