Abstract

PURPOSE:To offer a cordless telephone system provided with an alarm function which implement surer morning call function or the like in a slave set or a master set. CONSTITUTION:An alarm time is set by operating an alarm mode key 12 and a ten-key 11 of a master set 1. A control circuit 14 compares a current time with a set alarm time and sends an alarm time detection signal through a control channel to a slave set before a prescribed time of the alarm time such as 5sec. When a reply signal returns from the slave set through the control channel within 5sec, both the master set and the slave set are set to a predetermined talking channel. After lapse of 5sec, the master set sends an alarm signal to the slave set and the slave set sounds an alarm tone from a speaker. When the slave set operates an interrupt key while the alarm tone is sounded, the transmission of the alarm signal is stopped and the master set and the slave set are restored to the reception standby state. When no reply signal returns from the slave set within 5sec, the control circuit 14 emits an alarm sound from the speaker 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone device having an alarm function.

[0002]

2. Description of the Related Art A master unit having a transceiver connected to a telephone line, and a slave unit wirelessly connected to the master unit,
A cordless telephone device in which a child device is connected to an outside line via a parent device is very convenient because the child device can be freely carried as long as the child device is within a communication range, and it is becoming popular in recent years.

By the way, for example, JP-A-1-160120.
As disclosed in Japanese Patent Publication, an alarm function is added to an electric product and used for a wake-up call or the like. Recently, such an alarm function is used in a bedroom like a cordless telephone handset. It is preferable to add it to those that can be placed in the same manner.

[0004]

However, since the slave unit is driven by a secondary battery because of its portability and has a power switch to avoid unnecessary power consumption, the power switch is accidentally turned on. Leave it on and leave it in a place other than the charger,
If the battery runs out of power, or turn on the power switch
There is a possibility that it may be left in the FF state and left unattended. In this case, the child device does not operate, and the wake-up call and the like cannot be performed.

[0005]

A cordless telephone device of the present invention comprises a master unit having a transceiver connected to a telephone line and a slave unit wirelessly connected to the master unit. In the cordless telephone device in which the cordless handset is connected to the outside line via the cordless handset, the cordless handset requests the cordless handset to form a wireless line at a preset time, and the wireless line is connected within a predetermined time. When the notification signal is transmitted to the slave unit when it is formed, and the control unit that drives the notification unit when it is not formed is provided, the notification unit and the notification unit by receiving the notification signal from the master unit. Is provided with a control means for driving.

[0006]

Since the present invention is configured as described above, if the wireless line between the parent and the child is formed when the preset time comes, the notification is made on the handset side and the wireless line is connected. If it is not formed, a notification is made on the base unit side.

[0007]

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a block diagram of a master unit (1), (3) a receiving circuit for receiving a signal from a slave unit (2), (4) a transmitting circuit for transmitting a signal to a slave unit (2), (5) is a network circuit connected to the telephone line (L), and connects the receiving circuit (3), the transmitting circuit (4) or the handset (6) to the telephone line (L). (7) is a bell signal detection circuit for detecting a bell signal when an incoming call is received, and the detection output is a control circuit (1
4). (8) is a dial circuit for sending a dial signal of a dial number designated by the control circuit (14) to the network circuit (5), and (9) is a hook detection circuit for detecting on-hook and off-hook of the handset (6). , (10) is a keyboard including a ten-key pad (11) and an alarm mode key (12), and (13) is a speaker for generating an alarm sound. Reference numeral (14) is a microprocessor, which is a control circuit for controlling the entire master unit (1) and has a built-in timer for counting the current time.

FIG. 2 shows a block diagram of the slave unit (2),
Reference numeral (15) is a receiving circuit for receiving a signal from the base unit (1), and the received signal is amplified by the receiving speaker (17) via the amplifier (16). Reference numeral (18) is a transmission circuit for transmitting a signal from the slave unit (2) to the master unit (1), and an output signal of the microphone (19) for transmission and an output signal of the control circuit (25). Is being supplied. Reference numeral (20) is a speaker for generating an alarm sound of an incoming call or a sound different from the bell sound. Reference numeral (21) is a keyboard composed of a numeric keypad (22), a call key (23), an off key (24) and the like. Reference numeral (25) is a control circuit which is composed of a microprocessor and controls the slave unit (2) as a whole.

FIG. 3 is a flowchart of a program of a main part relating to alarm processing written in the master unit (1).
The operation will be described below based on this.

To set the alarm time, first, after operating the alarm mode key (12) of the master unit (1), input the desired time with the ten-key (11), and then again the alarm mode key (12). It can be performed by operating.

Then, the control circuit (14) of the master unit (1) compares the present time with the set alarm time, and when 5 seconds before the alarm time, an alarm time detection signal is sent by the control channel to the slave unit. (2) (step S-
1, 2). When the slave unit (2) receives this alarm time detection signal and a response signal is transmitted from the slave unit (2) through the control channel within 5 seconds, both the master unit (1) and the slave unit (2) Set to a predetermined call channel (step S-
3-6). After 5 seconds, the master unit (1) transmits an alarm signal to the slave unit (2) through the communication channel (step S-7), and the slave unit (2) which receives the alarm signal outputs an alarm sound to the speaker (20). ) Caused by. While this alarm sound is being generated, the off key (24) on the slave unit (2) side
Is operated and a cutoff signal is transmitted to the master unit (1) through the call channel, the master unit (1) stops transmitting the alarm signal (steps S-8 and 9). After that, both the master unit (1) and the slave unit (2) return to the reception standby state.

In the above description, when the response signal is not transmitted from the handset unit (2) within 5 seconds (when the power switch of the handset unit (2) is OFF, the battery of the handset unit (2) has no remaining power). In the case of etc.), the control circuit (14) of the parent device (1) is
3) an alarm sound is generated (step S-1)
0). In this state, the alarm mode key (1
When 2) is operated, the generation of the alarm sound is stopped (steps S-11 and 12).

In the above configuration, the alarm sound is generated, but if the answering machine is installed in the base unit (1), the alarm message is stored in the IC memory for storing the response message. May be stored in advance, and the message may be generated by the parent device (1) or the child device (2).

[0014]

Since the present invention is configured as described above, if a wireless line between a parent and a child is established at a preset time, a notification is made on the slave side and a wireless communication is made. When the line is formed, the notification is made on the side of the master unit, and even if the slave unit is not in the operating state for some reason, the wake-up call or the like can be performed more reliably.
