DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless handset of a home cordless telephone.

[0002]

2. Description of the Related Art In general, the cordless handset of a home cordless telephone is limited to only voice (call) communication means.
Recently, personal computer communication and the like using a telephone line at home are increasing.

FIG. 4 and FIG. 5 are diagrams showing a conventional method of connecting a personal computer to a telephone line when performing personal computer communication at home.

When a personal computer communication is to be performed at home, a modular cable 21 is extended from a modular jack 20 of a telephone line (NTT) as shown in FIG. 4 and connected to a communication modem 23 of a personal computer 22. Modem 2
3 to the cordless telephone / base unit 25 which is wirelessly connected to the cordless telephone / slave unit 24 and extend the modular cable 21 or connect a bifurcated modular jack adapter 26 as shown in FIG. Had a way to connect to.

[0005]

However, in the connection method described above, it is difficult for ordinary people to connect the cable by routing it from a room at home to the room, and it is dangerous for the cable to be left in the room. But it was.

The present invention solves the problem that it is difficult to connect a modem to a telephone line, and the cable is left unsafe when connected, and provides an apparatus that can easily connect a telephone line to a modem and use it safely. Is what you do.

[0007]

Therefore, according to the present invention, a separately installed modem is incorporated in a battery charger for a cordless telephone / slave unit, and a telephone line is transmitted from the cordless telephone / base unit by a switching circuit of the slave unit body. By entering the modem through the main unit and connecting to the main unit, the modular cable used for the connection between the telephone line's modular jack, modem, cordless telephone, and base unit can be reduced, Eliminate the above problems.

[0008]

FIG. 1 is a block diagram of a cordless telephone / slave unit having a built-in modem according to a first embodiment of the present invention. Battery charger 1 for cordless phones and handsets
A modem 2 is built in the battery charger (hereinafter referred to as a battery charger), and a switching circuit 3-1 of the cordless telephone / child device (hereinafter referred to as the child device) and the battery charger 1 are connected to a power supply terminal 1-1. , And a communication terminal 1-2 and a control terminal 1-3. Also, battery charger 1
Has a general-purpose connection terminal such as RS-232C or RS-422, and connects the personal computer 4 to the modem 2 with a general-purpose communication cable 5.

When the main unit 3 is attached to the battery charger 1, a telephone line (NTT) through the modular jack 6 is connected to the cordless telephone / base unit 7 (hereinafter referred to as base unit) by the switching circuit 3-1. The user enters the modem 2 through the slave main unit 3 and is connected to the slave main unit 3. That is, this is the same as the mode in which the modular cable 21 in FIG. In addition, 3-2 is a speaker & microphone, 3-3 is a communication circuit, and 3-4 is a wireless circuit.

Next, the operation of the first embodiment will be described.

At the time of transmission by data communication such as personal computer communication, a signal is transmitted from the modem 2 to the slave unit main unit 3 via the control terminal 1-3, and the slave unit main unit 3 determines when the dial button is pressed. The same operation is performed with master device 7 to establish a call with the telephone line. At this time, if data communication is being performed, the slave
The battery charger 1 is locked by the mechanical locking mechanism 1-4 and cannot be removed.

When making an outgoing call by voice, the slave unit body 3 is detached from the battery charger 1, or the dial button of the slave unit body 3 is operated while the battery unit 1 is attached to the battery charger 1. At this time, the connection between the slave unit main body 3 and the modem 2 is disconnected by the switching circuit 3-1 and the voice call with the speaker & microphone 3-2 becomes possible.

At the time of an incoming call, if the modem 2 has been designated to automatically answer the modem 2 from the personal computer 4, the modem 3 responds without sounding the speaker 3-2 of the slave unit body 3.

If no automatic response is specified, the handset main unit 3 is used in the same manner as a normal home cordless telephone.
The speaker 3-2 sounds and if the child device main body 3 is lifted, that is, if the child device 3 is detached from the battery charger 1, voice communication can be performed.

FIG. 2 is a block diagram of a cordless telephone / slave unit (PCMCIA interface) having a built-in modem according to a second embodiment of the present invention. PCMCIA is Pe
rsonal Computer Memorycard International Associati
Abbreviation for on, a PC of an arbitrary organization established in June 1989.
Refers to the International Association for Memory Cards.

The slave battery charger 10 incorporating the modem 2 has a connection terminal in the form of a PCMCIA card, and is connected by directly inserting it into a PCMCIA card slot 11 of a notebook computer or the like. Other configurations and operations are the same as those of the first embodiment,
Description is omitted.

FIG. 3 is a block diagram of a cordless telephone / slave unit having a built-in modular jack according to a third embodiment of the present invention.

The battery charger 12 has a built-in modular jack 12-1 and a signal detecting circuit 12 for causing the same operation as the telephone line (NTT) modular jack 6.
-2 is incorporated, and the switching circuit 3-1 of the slave unit 3 is incorporated.
And the battery charger 12 include a power supply terminal 1-1,
They are connected by a communication terminal 1-2 and a control terminal 1-3.

When the main unit 3 is attached to the battery charger 12, a telephone line is connected from the main unit 7 to the main unit 3 and the modular jack 12-1 in parallel. That is, this is the same as the mode in which the modular cable 21 in FIG.

Next, the operation of the third embodiment will be described.

A modular jack 12-1 built into the battery charger 12 is a modular jack 6 for a telephone line.
In the same manner as described above, it has a function of performing operations such as telephone conversation, dial signal reception, polarity inversion, and terminal calling.

At the time of transmission from the modem 13 connected to the built-in modular jack 12-1, the signal detection circuit 12-2 of the battery charger 12 detects transmission and dial signal, and If it can be connected to the telephone line via the device 6, the polarity is inverted.

When making an outgoing call by voice, the slave unit body 3 is detached from the battery charger 12 or the dial button of the slave unit body 3 is operated while being attached to the battery charger 12. At this time, the connection between the slave unit main body 3 and the modem 13 is disconnected by the switching circuit 3-1 and the voice communication with the speaker & microphone 3-2 becomes possible.

When an incoming call is received from the base unit 7, the call signal is sent to the built-in modular jack 12-1 at the same time as the speaker & microphone 3-2 of the main unit 3 is sounded. During the call via the built-in modular jack 12-1, if the slave unit main body 3 is detached, the line is disconnected. Therefore, during the call, the slave unit body 3 and the battery charger are mechanically locked by the mechanical lock mechanism 1. -4 locks and cannot be removed.

As described above, in the embodiment of the present invention, a configuration example in which one slave unit and one personal computer are provided has been described. However, if there are a plurality of slave units and personal computers, the communication function between the slave units is utilized. Data can be exchanged between PCs at home without having to route cables.

[0026]

As described above, according to the present invention, the telephone line can be connected to the personal computer by bringing the cordless telephone handset to the place where the personal computer is placed, and the telephone code is routed from room to room. The cable can be reduced, and PC communication can be performed without the hassle of connecting and the danger of having a telephone cord on the floor.

Further, in the case of a system in which the slave unit is inserted into the PCMCIA card slot of the personal computer, the connection is simplified and a communication cable is not required.
