The present invention relates to a simplified dialer device of a wired / wireless telephone. In particular, an auxiliary power source is provided in a fixed device of a wired / wireless telephone to enable dialing using a wired dialer and a wireless dialer as a wireless dialer. A simplified dialer device of a telephone.

In general, a typical wired / wireless telephone is fixed to a wired dialer and a wired / wireless telephone that generates dual tone multi-precision (weak DTMF below) using power from an exchange connected through a CO line. DTMF generation operation is performed by purchasing a wireless dialer that generates DTMF by using a power supply provided in the device and under the control of a microprocessor.

Conventional wired and wireless telephones equipped with a dialer as described above may be of the type shown in FIG. As shown in the figure, a conventional wired / wireless telephone includes a keypad 10, a microprocessor 20, a wireless dialer 30, a wired dialer 40, a telephone call circuit section 50, and a power supply section 60. It includes.

In the figure, the keypad 10 includes a numeric key for inputting a telephone number and a special key for performing various special functions in order to perform a desired telephone operation by a user.

The microprocessor 20 then controls the overall operation of the phone and generates data corresponding to the input signal from the keypad 10 to the wireless dialer 30.

The wireless dialer 30 also has a DT corresponding to the data from the microprocessor 20.

Generates MF, and wired dialer 40 generates DTMF corresponding to the telephone number input from keypad 10.

At this time, the wire-line dialer 40 directly generates a DTMF corresponding to the telephone number input from the keypad 10 by using a power source provided by an exchange through a telephone line.

On the other hand, the telephone call circuit unit 50 amplifies DTMF generated from the wireless dialer 30 and the wired dialer 40, and transmits the DTMF to the exchanger for remote control via a telephone line.

Finally, the power supply unit 60 is a means for supplying power to each component.

However, there is a problem in that the complexity of the circuit and the manufacturing cost are increased by providing the wired dialer and the wireless dialer, respectively, which perform the same function in the phone equipped with the component.

Accordingly, the present invention is to solve the problems of the prior art as described above, to provide a simplified power supply of a wired and wireless telephone to provide a power supply to prepare for a power failure and to generate a DTMF with one dialer to perform a telephone operation The purpose is to provide a device.

In order to achieve the above object, the present invention is a simplified dialer device of a wired / wireless telephone having a fixed device and a portable device, which is installed in the fixed device, and which uses a numeric key to perform an operation of a desired phone. A keypad equipped with a special key, a microprocessor for controlling the overall operation of the telephone corresponding to an input signal from the keypad, and from the microprocessor based on a dialing signal through the portable device and a dialing signal from the keypad. A dialer for generating a DTMF (DUAL TONE MULTI-FREQUENCY) in response to a control signal of the telephone, a telephone call circuit unit for amplifying and transmitting the DTMF generated from the dialer through a telephone line, and supplying power to each component. A main power supply for supplying and at the time of shutting off the power from the main power supply; And it provides the device simplification of the die allergens wired or wireless telephone comprising the auxiliary power supply unit for charging by supplying power to the microprocessor.

Other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a fixed device of a wired / wireless telephone having a simplified dialer device according to the present invention.

In the same figure, the present invention includes a keypad 10, a microprocessor 20, a dialer 30, a telephone call circuit unit 40, a main power supply unit 50, an auxiliary power source 60.

As apparent from the figure, the simplified dialer device of the present invention is configured by integrating one connected in parallel with the main power supply unit 50 to supply power when the power supplied from the main power supply unit 50 is interrupted due to a power failure. Its main structural feature is that the remaining components, except for these components, are substantially similar to conventional devices.

Next, the operation process of the present invention will be described in detail with reference to FIG.

First, when the telephone loop is turned on by the user (step 200), it is determined whether there is a dial input through the keypad 10 (step 202).

If there is a dial input as a result of the determination in this step, the microprocessor 20 detects this and generates data corresponding to the input signal to the dialer 30 (step 204).

At this time, in the conventional case, unlike the present invention, the input dial signal is divided into a wired or wireless type, and when the wired type is used, the DTMF is directly generated by the wired dialer. Allergens generated DTMF.

The dialer 30 receiving the data then generates a corresponding DTMF (step 206), amplifies the DTMF by the telephone call circuit unit 60 and transmits it to the exchange via the telephone line (step 208).

Thus, through the above process, the simplified dialer device of the present invention generates DTMF corresponding to the desired dial signal input through the keypad of the fixed device as well as the portable device through one dialer 30. do.

As described above, according to the present invention, by adopting a dialer in the wired or wireless telephone, there is an effect of simplifying the telephone circuit and reducing the manufacturing cost.
