Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a portable device in a wireless fax machine applied to the present invention. Referring to FIG. 1, the portable device controller 12 controls the overall operation of the interior. The keypad 10 includes keys for setting various functions and modes and numeric keys for performing a dialing function, and outputs key data corresponding to a key pressed by the user to the portable device controller 12. The RF transmitter 20 outputs a transmission voice signal output from the voice amplifier 14 or data output from the portable device controller 12 through an antenna under the control of the portable device controller 12. The RF receiver 24 demodulates the signal received through the antenna and outputs the demodulated signal to the voice amplifier 14 and simultaneously outputs control data to the portable device controller 12. The signal controller 28 controls the RF transmitter 20 and the RF receiver 24 at a transmission / reception frequency based on control data output from the portable device controller 12. The voice amplifier 14 amplifies the voice signal input from the transmitter 18 or the voice signal received from the RF receiver 24.

2 is a block diagram of a facsimile system with a radiotelephone function according to an embodiment of the present invention. Referring to FIG. 2, first of all, the whole system includes three components, and includes a fixed device wireless circuit, a facsimile circuit, and a power supply.

In this case, the fixed device wireless circuit unit is composed of a wireless circuit control unit 202, a line interface unit (LIU) 204, a wireless processing unit 206, a sensor unit 208, the operation unit 210, the wireless circuit control unit 202 To perform a wireless telephone call. In addition, the facsimile circuit unit includes a facsimile control unit 212, a modem 214, a memory unit 216, a scanner 218, and a printer 220 to perform a facsimile call under the control of the facsimile circuit control unit 202. do. Finally, the power supply unit includes a power supply unit 222 and a power switching unit 224 to supply power to the above-described components.

Then, each configuration in the above-described system will be described in more detail.

The operation unit 210 includes various numeric keys and function keys and has a display window for displaying the state of the system. The radio circuit controller 202 controls the overall operation of the radio circuit, and is used as a master controller in the present invention to generate a control signal for supplying power to operate the facsimile control unit 212 and the facsimile circuit unit during the facsimile call. In addition, the control unit 212 generates a control signal for shutting off power to the facsimile control unit 212 and the facsimile circuit unit. The LIU 204 selectively connects the telephone line incoming from the exchange with the wireless telephone call load and the facsimile call load under the control of the radio circuit controller 202 to form a call loop. The radio processing unit 206 is RF-transmitting unit for band-modulating and outputting a radio wave through an antenna by modulating a signal input by call switching from the LIU 204 under the control of the radio circuit controller 202 therein, and received through the antenna. A signal for controlling the RF transmitter and the RF receiver at a transmission / reception frequency based on channel data output from the radio circuit controller 202 and demodulating the signal into a signal of a voice band and outputting the signal to the radio circuit controller 202. It consists of a control unit. The facsimile control unit 212 controls the overall operation of the facsimile according to the control program, and is used as a slave control unit in the system of the present invention. The modem 214 demodulates a modulated signal input through the LIU 204, and modulates and outputs a signal to be sent to a telephone line through the LIU 204. The memory unit 216 includes a ROM and a RAM, and the ROM stores a control program executed by the facsimile control unit 212. The RAM stores image data received or read under the control of the facsimile control unit 212 when performing a specific function of the facsimile, or temporarily stores data generated when the facsimile performs a function. The scanner 218 scans an original, converts an image of the original into secondary information, and applies the same to the facsimile control unit 218. The printer 220 prints the received image data or the read image data under the control of the facsimile control unit 220. The power supply unit 222 supplies power to the wireless circuit unit and the power switching unit 224. The power switching unit 224 cuts off or supplies power to the facsimile circuit unit and the facsimile control unit 212 under the control of the radio circuit controller 202.

As a result, when there is a voice transmission mode selection from any one of a plurality of portable devices connected to the stationary device of the facsimile, and input of an identification number of a second mobile device to which voice information is to be transmitted, The wireless circuit controller 202 of the fixed device controls the internal operation mode to switch to the voice transmission mode, and then receives the voice message transmitted from the first mobile device and stores the voice message in a specific storage area of the internal memory unit 216. . Thereafter, the wireless circuit controller 202 of the fixed device controls the corresponding unit to automatically call the input identification number of the desired second portable device to form a call, and stores the first portable device stored in the memory unit 216. Automatically send voice message.

The operation of the present invention will now be described in detail with reference to the control flow of FIG. 3 with reference to the block diagrams of FIGS. 1 and 2 described above.

3 is a flowchart for controlling voice message transmission between portable devices in a wireless fax machine according to an embodiment of the present invention. Referring to FIG. 3, first, the control flowchart is described based on the radio circuit controller 202 of the fixed device which is the master controller.

In step 302 to 306, when the device inputs a voice transmission mode selection key from a specific first mobile device in a standby state, and thus inputs an identification number for calling the second mobile device, the wireless circuit controller of the fixed device 202 controls the corresponding mode in the device to switch the operation mode to the voice transmission mode. In this case, the wireless circuit controller 202 of the fixed apparatus performs step 308 to store the voice message transmitted through the first portable apparatus in a specific storage area of the memory unit 216. Thereafter, in step 310, the radio circuit controller 202 detects whether the storing of the received and stored message is terminated. In this case, when the storage of the received and stored message is terminated, the wireless circuit controller 202 controls to attempt to make a call by automatically calling the identification number of the second portable device in steps 312 to 316. When a call is made, the voice message stored in the memory unit 216 is automatically transmitted to the second portable device, and the program is terminated.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

The present invention as described above has the advantage that the user can use the product more convenient by allowing the user to use the product by mutually transferring the voice messages between the portable device in the facsimile with the addition of a radiotelephone function.
