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 for wireless communication.

[0002]

2. Description of the Related Art A conventional cordless telephone system will be described with reference to FIG. FIG. 3 is a configuration diagram showing a configuration of a conventional cordless telephone device.

In FIG. 3, a master unit 50 connected to the telephone line 3, a slave unit 60 for performing wireless communication with the master unit 50, and a charging stand 70 for charging the slave unit 60 are provided.

The base unit 50 has a handset 51 having a receiving section and a transmitting section, and a key operation section 52 for inputting a dial number.

[0005] The slave unit 60 is connected to a key operation unit 61 for inputting a dial number and a charging terminal 71 provided on the charging stand 70 to charge the slave unit 60 with electric power (not shown). A charging terminal is provided.

Next, the operation of the conventional cordless telephone device will be described. The slave unit 60 is usually installed on a charging stand 70 for charging. When the slave unit 60 is removed from the charging stand 70, the charging of the slave unit 60 is stopped.

The slave unit 60 transmits a dial number to the master unit 50 by an input from the user's key operation unit 61, and the master unit 50 transmits the transmitted dial number to the telephone station via the telephone line 3. Send to 4.

Therefore, according to the above-mentioned conventional cordless telephone device, the dial number can be transmitted and input not only from the master device 50 but also from the slave device 60.

[0009]

However, according to the above-mentioned conventional cordless telephone device, although the dial number can be transmitted and input even in the cordless handset 60, in recent years, the cordless handset 60 is required to be compact. Therefore, there is a problem in that the key operation unit 61 provided in the cordless handset 60 is downsized and an erroneous operation occurs when a dial number is input.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cordless telephone device capable of reliably preventing an erroneous operation when a dial number is input. .

[0011]

In order to achieve the above object, according to the cordless telephone device of the present invention, a master unit connected to a telephone line, a slave unit wirelessly communicating with the master unit, and the slave unit. A cordless telephone device having a charging stand for charging the electric power of, the operating stand for inputting a dial number and a light emitting means for converting the inputted dial number into an infrared signal and outputting the infrared signal. The slave unit has a control unit for converting the infrared signal output from the light emitting unit, decoding the dialed number, and transmitting the dial number to the master unit.

[0012]

With this configuration, according to the cordless telephone device of the present invention, the operating means for inputting the dial number is provided on the charging stand having the same size as the parent machine, and the data communication between the charging stand and the child machine is performed. Since it is done with infrared rays, when making a call with the slave unit, dial the dial number using the operating means that is almost the same size as the master unit installed on the charging stand. It is possible to reliably prevent erroneous operation of the number.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cordless telephone device of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of a cordless telephone device of the present invention.

In FIG. 1, a master unit 10 connected to the telephone line 1, a slave unit 20 that wirelessly communicates with the master unit 10, and a charging stand 30 that charges the slave unit 20 with electric power are provided. .

The base unit 10 has a handset 11 having a transmitting / receiving unit and a key operating unit 12 for inputting a dial number.
And have. The charging stand 30 contacts a charging terminal (not shown) of the slave unit 20 to charge the slave unit 20 with electric power, a key operation unit 32 for inputting a dial number, and the key operation unit 32. And a light emitting unit 33 which converts the dial number input at to into infrared rays and emits the infrared rays. The base unit 10 and the charging stand 30 have substantially the same size.

The handset 20 has a handset 21 having a transmitter / receiver section, a light receiving section 22 for receiving infrared rays from the light emitting section 33 of the charging stand 30, and decodes the dial number from the received infrared rays. An RF control unit 23 that controls wireless communication with the base unit 30 is included.

Next, the operation of the cordless telephone system will be described with reference to FIG. When making a call with the slave unit 20, the user dials the key operation unit 32 provided on the charging stand 30 to convert the dial number into infrared light and emit light from the light emitting unit 33.

The light receiving section 22 of the slave unit 20 receives the infrared ray from the light emitting section 33 and supplies it to the RF control section 23. The RF control unit 23 converts the infrared rays to decode the dial number, and transmits the decoded dial number to the base unit 10.

The master unit 10 sends the dial number transmitted from the slave unit 20 to the telephone station 2 via the telephone line 1.

Therefore, according to the above embodiment, the key operating unit 32 for inputting the dial number is provided on the charging stand 30 having the same size as that of the base unit 10, and the charging stand 30 and the slave unit 20 are provided.
Since the data communication with the device is performed by infrared rays, when the mobile device 20 makes a call, the charging base 30
The key operation unit 32 having substantially the same size as the base unit 10 provided in the
By inputting the dial number with, it is possible to reliably prevent erroneous operation of the dial number.

Further, since the slave unit 20 is not provided with a key operation section, the slave unit 20 is extremely lightweight,
You can talk for a long time more easily than before.

In the above embodiment, the key operation unit 1
The cordless telephone device having the master device 10 including the handset 2 and the handset 11 has been described, but in the case of the cordless telephone device having the master device 40 without the key operation unit and the handset as shown in FIG. I cannot make calls. Therefore, it is needless to say that when the cordless telephone device of the present invention is applied, the effect can be further enhanced because the communication using the cordless handset 20 is mainly used.

[0023]

According to the cordless telephone device of the present invention configured as described above, the charging stand having the same size as the master unit is provided with the operating means for inputting the dial number, and the charging stand and the slave unit. Since the data communication with the device is performed by infrared rays, when making a call with the slave unit, enter the dial number with the operating means that is almost the same size as the master unit installed on the charging stand. By doing so, it is possible to reliably prevent erroneous operation of the dial number.
