DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm clock capable of automatically adjusting an alarm time.

[0002]

2. Description of the Related Art In an alarm clock with a snooze mechanism,
During the alarm time and the alarm notification is being performed,
By turning on the snooze switch, the alarm notification starts again after a certain time has elapsed. Therefore, the actual use of this kind of alarm clock is
For example, if it is absolutely necessary to wake up at 6:00 AM, it is common to set an alarm time about 15 minutes before that time and wake up after performing the snooze operation two or three times. is there.

[0003]

According to the above, even if the bedtime of the previous day is late and it is desired to sleep for a little longer time, the alarm is notified at the alarm time. Can not.

[0004] It is an object of the present invention to adjust the sleep time by changing the alarm notification time within an allowable time range according to the bedtime.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a bedtime is scheduled.
Judge whether it is later or earlier than the set time.
The above object is achieved by providing a control means for delaying the alarm time by an allowable time as compared with the case where it is earlier .

[0006]

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

In FIG. 1, 1 is a clock signal generator,
Reference numeral 2 denotes a current time clock circuit which constitutes a clock means. Reference numeral 3 denotes an allowable time storage circuit for setting an allowable time for adjusting an alarm time. Reference numeral 4 denotes an alarm set switch, and 5 denotes a key, which is used to set an alarm time, a permissible adjustment time thereof, a standard bedtime, and the like. 6 the alarm tone generator constituting the alarm unit, 7 A color <br/> arm time memory circuit, 8 is a control circuit constituting control means,
It comprises a CPU, a ROM, and the like. Reference numeral 9 denotes a time display unit, and reference numeral 10 denotes a standard sleeping time storage circuit.

Next, the operation will be described with reference to FIG. First, using the key 5, an alarm time, an allowable adjustment time thereof, and a standard bedtime are set. For example, suppose that the time that must occur is 7:00 AM, AM 6:45 is set as the alarm time, and ± 15 minutes is set as the allowable adjustment time. The standard bedtime is a time when the user goes to bed, for example, PM11: 0.
It is assumed that 0 is set.

When the user goes to bed and closes the alarm set switch 4 to set an alarm, the difference t between the current time Tp and the standard bedtime Ts at that time is calculated (step). That is, the time when the alarm is set is regarded as the actual bedtime, and the standard bedtime PM11: 00
It is to determine how much earlier or later you went to bed.

Next, whether or not the difference t falls within the range of -1 hour≤t≤ + 1 hour, that is, the bedtime is PM1
It is determined whether the time is between 0:00 and 12:00 (step). Within this range, the currently set alarm time AM6: 45 becomes the alarm time as it is. If t is not in the range of −1 hour ≦ t ≦ + 1 hour, it is determined whether or not t is in the range of t> +1 hour (step), and if t is included in the range of t> +1 hour, If the time has passed AM 12:00, the alarm time is (time stored in alarm time storage circuit 7) + (maximum time 15 minutes stored in allowable time storage circuit 3) = AM 7:00. (Step). t
Is not within the range of t> +1 hour, the alarm time is (time stored in the alarm time storage circuit 7) +
(Minimum stored in the allowable time storage circuit 3 time - 15
Minute) = 6: 30 AM (step).

In this manner, the alarm time is adjusted within a range of ± 15 minutes according to the bedtime. Current time clock circuit 2
When the coincidence of the current time obtained from the above and the alarm time receiving the above operation is detected (step), the alarm sound generator 6 operates to generate an alarm sound (step). It is assumed that the alarm sound is stopped by opening the alarm set switch 4.

An example in which a snooze function is added to this configuration will be described with reference to the flowchart of FIG. This flowchart follows the steps of FIG. When the snooze switch (not shown) is turned on and the snooze is set after the alarm is generated, it is determined whether or not the previously obtained t is greater than one hour (step). If t is smaller than 1 hour, that is, if the user goes to bed before 12:00 AM , a snooze operation is started (step), and a fixed time (about 5 minutes).
Later, the alarm sounds again and functions as a normal snooze alarm clock.

However, when t> 1 hour, that is, A
If you went to bed M 12:00 too it is barely of time
Since an alarm sound is generated at 7:00 AM , the user goes to sleep when entering the snooze operation. In this case, snooze is disabled, and the alarm sound does not stop even if the snooze switch is turned on. Therefore, unless the alarm set switch is opened, the alarm sound does not stop and can be reliably generated.

Next, another embodiment will be described with reference to FIG. Reference numeral 11 denotes a standard sleep time storage circuit, in which the average sleep time of the user is set by the key 5. Reference numeral 12 denotes a sleep time storage circuit that stores an actual sleep time. The same numbers as those in FIG. 1 indicate the same components.

Next, the operation will be described with reference to FIG. Also in this case, the calculation and determination are performed by the control circuit 8. First, the key 5 is used to set the standard sleep time Tav to, for example, 8 hours. It is determined whether or not the alarm set switch 4 is set, and when the alarm set switch 4 is set, t ′ = Tav− (Ta−Tp) is calculated. Here, Ta is the alarm time, Tp is the current time at the time of alarm setting, and the actual sleep time is calculated by (Ta−Tp), and the difference from the standard sleep time Tav is obtained. The following operation is the same as that described in the previous embodiment.

In this embodiment, the sleep time storage circuit 1
By storing the actual sleep time (Ta-Tp) in 2, this can be displayed.

In the above embodiment, the sound is used as the alarm means. However, the alarm means by vibration may be used instead of the sound, and the means for changing the magnitude of the sound or vibration over time may be used. Similar effects can be obtained.

Note that a mode switch for selecting the above function may be provided, and the mode switch may be used to notify an alarm at a conventional alarm time by switching the mode switch.

[0019]

As described above in detail, the alarm clock of the present invention determines whether the bedtime is later or earlier than the preset time.
Judgment is made, and if it is late, it will alert for an allowable time
Since the sleep time is delayed , it is possible to sleep just to the permissible range when sleeping later than usual.
