[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snooze alarm clock equipped with a human body detection sensor.

[0002]

2. Description of the Related Art Conventionally, when the snooze switch is operated once when an alarm is issued, the snooze function is started, and when the snooze switch is operated twice, an alarm is switched every 24 hours, that is, an alarm set for the next day is performed. An alarm clock is disclosed in JP-A-63-134997.
No. 6,086,045.

[0003]

In the above, the user has to judge whether the snooze switch is operated once or twice when the alarm is issued, which is a troublesome operation when waking up. , The user feels that he / she has sufficiently awakened when the alarm notification was stopped.
If you repeat the operation and perform the next day's alarm set and then go to sleep again, the snooze function required in this case does not work, and you may not be able to wake up at the scheduled time.

An object of the present invention is to appropriately switch the snooze operation and the alarm set for the next day without performing a troublesome operation.

[0005]

Means for Solving the Problems After the alarm notification is temporarily stopped by operating a snooze switch, when the human body detection means detects a human body within a desired range, the human body detection means is notified again and the human body detection means detects the desired range. The above object is achieved by providing a control means for resetting the alarm notification the next day when it detects that there is no human body inside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in the drawings.

In FIG. 1, reference numeral 1 denotes a human body detection circuit which constitutes human body detection means. In this example, an IR sensor (infrared sensor) is provided to detect a human body in a human body detection area. Reference numeral 2 denotes a time counting circuit which constitutes a time measuring means and measures the present time. 3 is an alarm time storage circuit, which is composed of RAM,
Remember the alarm time. Reference numeral 4 is a comparison circuit, which is a timing circuit 2
When it is detected that the present time obtained from the present time matches the alarm time stored in the alarm time storage circuit 3, a coincidence detection signal is output. Reference numeral 5 is a counter, and 6 is an alarm output section which constitutes an informing means for issuing an alarm. Reference numeral 7 denotes an input unit, which includes a snooze switch 8 and a sound stop switch (not shown). A display unit 9 displays the present time, alarm time, and the like. Reference numeral 10 is a control circuit which constitutes a control means, and is C
It is composed of PU, ROM, RAM and the like.

Next, the operation will be described with reference to FIG. Now, the human body detection area of the human body detection circuit 1 is used as a sleeping place for the user.

When the present time reaches the alarm time stored in the alarm time storage circuit 3 (step a), the comparison circuit 4 sends a coincidence detection signal to the control circuit 10 and the control circuit 1
For 0, the alarm output unit 6 is notified of the alarm (step b). When the snooze switch 8 is closed (step c), the control circuit 10 causes the alarm output unit 6 to operate.
The alarm notification from (step d) is stopped, and the counter 5 is operated to count for a fixed time (for example, 5 minutes) (step e). When the human body detection circuit 1 detects a human body in the human body detection area at the end of counting (steps f and g),
The control circuit 10 causes the alarm output unit 6 to notify the alarm again (step h). That is, the snooze operation is executed. If no human body is detected in the human body detection area at the end of counting (steps f and g), the control circuit 10 resets the alarm the next day (step i).

That is, after a lapse of a certain time after the alarm is stopped, if the user does not wake up and is still in the sleeping place, the snooze operation is executed, and the user wakes up and leaves the sleeping place. Then, the alarm will be set again the next day.

[0011]

As described in detail above, the snooze alarm clock of the present invention snoozes when the human body detecting means detects a human body within a desired range after the alarm notification is temporarily stopped by operating the snooze switch. When the human body detecting means executes the operation and detects that the human body does not exist within the desired range, the alarm notification is reset to the next day. After a certain time has passed since the alarm was stopped by operating the snooze switch,
If the user does not wake up and is still in the sleeping place, the snooze operation is executed, and when the user wakes up and goes out of the sleeping place, the alarm can be reset to the next day, which is a troublesome operation. The snooze operation and the alarm set for the next day can be appropriately switched without using them.
