Description

TECHNICAL FIELD The present invention relates to a cordless telephone with an alarm function.

[Prior Art] A conventional telephone is installed in a predetermined place, and when using the telephone, it goes to that place, but it is convenient and convenient to keep the telephone near you. Recently, a cordless telephone that can easily move a cordless telephone subunit that is charged by a charger on the master unit side is on the market, and many people use the cordless telephone subunit when sleeping by putting it on a pillow.

On the other hand, an alarm clock is often placed on the pillow while sleeping to wake up, and a cordless telephone with an alarm function in which a clock with an alarm function is combined with a cordless telephone is conceivable.

[Problems to be solved] The above cordless telephone with an alarm function is placed on the pillow with the cordless telephone subunit separated from the charger when sleeping, but in this case, whether the storage battery of the cordless telephone subunit has the alarm time or not. I am worried if I do not know in advance.

Also, after the alarm is notified and the alarm is turned off, if the battery is forgotten to be attached to the charger and is left as it is, the battery will run out, and the battery cannot be used immediately the next time it is used.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cordless telephone with an alarm function that can know whether or not a cordless telephone subunit can be operated until an alarm time when it is detached from a charger, and can prevent forgetting to charge after alarm notification. I am trying.

[Means for Solving the Problem] The present invention provides a clock circuit that measures the current time, an alarm time storage circuit, an alarm set switch, and an alarm set state by the alarm set switch, in which the clock circuit measures time. Alarm signal generating means for generating an alarm signal when the present time and the alarm time stored in the alarm time storage circuit match, a storage battery to be the power source of the cordless telephone slave unit, and for charging this storage battery Detecting means for generating an output signal when the cordless telephone slave unit is detached from the charger, and when an output signal is generated from the detecting means in an alarm set state by the alarm set switch, An operable time calculation circuit for calculating the operable time of the cordless telephone subunit by a storage battery; , When the operable time calculated by this operable time calculation circuit is shorter than the time from the current time measured by the clock circuit to the alarm time stored in the alarm time storage circuit, an alarm signal is output. A first alarm signal generating circuit for generating the alarm signal is provided to generate an alarm signal when the cordless telephone subunit is detached from the charger and when the operable time of the storage battery does not reach the alarm time. In addition, more than a predetermined time from when the alarm was turned off by the alarm set switch,
The above problem is solved by providing a second alarm signal generating circuit for generating an alarm signal when an output signal is generated from the detecting means, and preventing forgetting to charge after alarm notification. is there.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 5 is an alarm signal generating means for generating an alarm signal when an output is generated from the comparison circuit 3 in the alarm set state by the alarm set switch 4, 6 is a display section for displaying the present time, the alarm time and the like, 7 Is a keyboard including a mode switch for switching the display of the display unit 6, a timing switch for timing the current time, an alarm time setting switch, and the like. 8 is a storage battery that serves as a power source for the cordless telephone subunit, 9 is a telephone circuit, 10 is a transmission / reception circuit for transmitting / receiving a call signal and the like to / from a cordless telephone master unit (not shown), 11 is charging for charging the storage battery 8. Means for producing an output when the cordless telephone subunit is disconnected from the device (not shown),
Reference numeral 12 is an operable time calculation circuit for calculating the operable time of the cordless telephone subunit by the storage battery 8 when the output from the detection means 11 is generated in the alarm set state by the alarm set switch 4, and 13 is the operable time calculation circuit 12 1st alarm signal generation that generates an alarm signal when the operable time calculated in step 1 is shorter than the time from the current time measured by the clock circuit 1 to the alarm time stored in the alarm time storage circuit 2 When the output signal is generated from the detecting means 11 when the circuit, 14 is turned off by the alarm set switch 4, the circuit 14 starts timing, and when the output signal is continuously generated from the detecting means 11 for a predetermined time or longer. A timer circuit that generates an output, and 15 is a second alarm signal generation circuit that generates an alarm signal according to the output from the timer circuit 14. 16 is a speaker driven by signals from the alarm signal generating means 5, the first alarm signal generating circuit 13 and the second alarm signal generating circuit 15, and 17 is an operable time calculating circuit.
A control circuit for controlling whether or not the operable time calculated in 12 is shorter than the time from the current time measured by the clock circuit 1 to the alarm time stored in the alarm time storage circuit 2. Is.

Next, an alarm sound generating operation when the storage battery 8 does not have an alarm time will be described with reference to the flowchart of FIG.

When the detection means 11 is in the closed state, that is, when the cordless telephone subunit is detached from the charger, the alarm set switch 4 sets the alarm set state, and the operable time calculation circuit 12 detects the voltage of the storage battery 8. Based on this voltage value, the operable time of the cordless telephone subunit by the storage battery 8 is calculated (step).

Next, the control circuit 17 calculates the time from the current time measured by the clock circuit 1 to the alarm time stored in the alarm time storage circuit 2 (step).

Subsequently, the control circuit 17 compares the operable time with the time until the alarm time. If the operable time is shorter, the first alarm signal generating circuit 13 generates an alarm signal and the speaker is activated. An alarm sound is generated from 16 (step).

By the above operation, when the cordless telephone subunit is detached from the charger and is in the alarm set state,
When the operable time is shorter than the time until the alarm time, an alarm sound is generated. This alarm sound may be, for example, a voice saying "The battery does not run until the alarm time."

Next, an alarm sound generation operation for forgetting to charge after the alarm is stopped will be described with reference to the flowchart of FIG.

When the detection means 11 is in the closed state, that is, when the cordless telephone subunit is detached from the charger, an alarm sound is generated, and subsequently, when the alarm is stopped, the timer circuit 14 starts timing ( Step).

Before the predetermined time is measured by the timer circuit 14, the detection means
If 11 is opened, that is, if the cordless telephone subunit is attached to the charger, no alarm sound is generated (step).

On the other hand, a signal is output when the timer circuit 14 finishes measuring the predetermined time with the detection means 11 in the closed state, whereby an alarm signal is generated from the second alarm sound generation circuit 15 and an alarm sound is output from the speaker 16. Is generated (step).

By the above operation, an alarm sound is generated when the cordless telephone subunit is detached from the charger, and then an alarm sound is generated when the cordless telephone subunit is not charged for a predetermined time or more after being turned off. . This alarm sound may be, for example, a voice saying "please charge."

In the above embodiment, the alarm sound is generated from the speaker 16 based on the alarm signals from the first alarm signal generation circuit 13 and the second alarm signal generation circuit 15, but the present invention is not limited to this. Alternatively, an alarm may be given by a display based on each of the above alarm signals.

[Effect] According to the present invention, when the cordless telephone subunit is detached from the charger and in the alarm set state, the operable time of the cordless telephone subunit by the storage battery is from the current time to the alarm time. Since the alarm is issued when the time is shorter than, it is possible to prevent failures such as when the battery runs out during sleep and you do not understand even if you receive a call.

Further, after charging the alarm, an alarm is given when charging is not started within a predetermined time. As a result, for example, when alarm notification is used for wake-up, since the storage battery consumes a lot of power during sleep, it is necessary to charge the battery after the alarm is turned off. It can be surely prevented. If you charge it, the battery will run out, and you will not know when someone calls you. Or you can avoid the situation where you will not be able to use it the next time you call.
