3 is a flowchart illustrating a multi-mode setting method of a multi-function phone according to the present invention. Steps 200 to 230 detect whether the mode input key is pressed when the multi-function phone is in the auto-answer standby state. Steps 240, 330, and 420 are processes for determining which mode the mode inputted by the dial button corresponds to, and steps 250, 340, and 450 are performed by the corresponding mode. If it is determined, the process for displaying the value previously stored in the memory in each corresponding mode, and steps 260 and 270, 350 and 360, 460 and 470 are the values entered in each corresponding mode and the displayed previous value stored in the memory. Steps 280, 370, and 480 are for comparing values, and if the values input in the corresponding modes are the same as the values previously stored in the memory, the corresponding values are previously displayed in the corresponding modes. The process returns to the process of displaying the value stored in the memory, and if it is not the same, it is a process for displaying the values input in the respective modes, and the steps 290 to 320, 380 to 410, and 490 to 520 are again performed. When the mode input key is pressed, it detects that the mode input is completed and saves the values input in the corresponding mode in the memory.

The operation of the present invention will now be described with reference to FIGS. 2 and 3.

Here is an example of a wired / wireless answering machine as a multifunction telephone. The power supply unit 10 generates a predetermined voltage and applies it to the microcomputer 60.

Hereinafter, the operation of the microcomputer 60 will be described. First, the code for the multiple mode is set in the microcomputer 60. In operation 200, the main program stored in the memory 30 is performed.

In step 210, it is checked whether the answering machine is in the auto answer standby state and returns to step 200 if it is not in the auto answer standby state. In step 210, it is checked whether the mode input key 20 is pressed (step 220). ).

When the mode input key 20 is not pressed in step 220, the process returns to step 200, and when the mode input key 20 is pressed, the display unit 100 is operated by the driver 90 to prepare for mode input. The state is visually displayed (step 230). The display unit 100 is composed of seven segments.

In operation 240, after the operation 230 is performed, it is checked whether the mode pressed by the dial button 70 is the ring number input mode. If the operation is not the ring number input mode, the process proceeds to step 330. The ring number stored in the display unit 30 is displayed on the display unit 100 (operation 250).

In operation 260, the dial button 70 checks whether a new ring number different from the previous ring number displayed on the display unit 100 is input, and if 20 seconds has elapsed when the same ring number is input (270). Step 20) If 20 seconds have elapsed, the flowchart ends. If 20 seconds has not elapsed, the flow returns to step 250. When a ring number different from the previous ring number is input, the new ring number is displayed on the display 100 (operation 280).

In operation 290, after the operation 280 is performed, if the mode input key 20 is pressed again, if the mode input key 20 is not pressed, it is checked whether 20 seconds have elapsed (operation 300) and 20 seconds have not elapsed. If no, return to step 290, and if 20 seconds elapses, step 310 is performed. When the mode input key 20 is pressed in step 290, a new ring number is stored in the memory 30 (step 310).

In operation 320, after the operation 310 is performed, the display unit 100 indicates that the new ring number is stored in the memory 30 and then ends the flowchart.

In step 330, if it is not the ring number input mode in step 240, it is determined whether the reception message recording time input mode is pressed. If the reception message recording time input mode is not pressed, the process proceeds to step 410 and the reception message recording time is determined. When the input mode is pressed, the reception message recording time previously stored in the memory 30 is displayed on the display unit 100 (step 340).

In operation 350, the dial button 70 checks whether a new received message recording time different from the previous received message recording time displayed on the display unit 100 is input, and 20 seconds have elapsed when the same received message recording time is input. If 20 seconds have elapsed, the flowchart is terminated, and if 20 seconds have not elapsed, the flow returns to step 340. In addition, when a reception message recording time different from the previous reception message recording time is input, the new reception message recording time is displayed on the display unit 100 (step 370).

In operation 380, after performing operation 370, it is checked whether the mode input key 20 is pressed again. If the mode input key 20 is not pressed, it is checked whether 20 seconds have elapsed (operation 390). If no, return to step 380, and if 20 seconds have elapsed, perform step 400. In operation 380, when the mode input key 20 is pressed, a new received message recording time is stored in the memory 30 (operation 400).

In operation 410, after the operation 440 is performed, the display unit 100 indicates that the new reception message recording time is stored in the memory 30, and then ends the flowchart.

In step 420, if it is not the incoming message recording time input button in step 330, it is determined whether the password input mode is pressed by the dial button 70, and if the password input mode is not pressed, it is checked whether 20 seconds have elapsed. In step 430, when 20 seconds have elapsed, the answering machine is left in the auto answer standby state (step 440). If 20 seconds has not elapsed, the process returns to step 230. When the password input mode is pressed, the password previously stored in the memory 30 is displayed on the display unit 100 (operation 450).

In operation 460, the dial button 70 checks whether a new password different from the previous password displayed on the display unit 100 is input, and checks whether 20 seconds have elapsed when the same password is input (operation 470). If 20 seconds have elapsed, the flowchart ends. If 20 seconds has not elapsed, the flow returns to step 450. If a password different from the previous password is input, the new password is displayed on the display unit 100 (step 480).

In step 490, after the operation 480 is performed again, the mode input key 20 is checked again. If the mode input key 20 is not pressed, it is checked whether 20 seconds have elapsed (step 500). If no, the process returns to step 490, and if 20 seconds elapses, the process proceeds to step 510. When the mode input key 20 is pressed in step 490, the new password is stored in the memory 30 (step 510).

In operation 520, after the operation 510 is performed, the display 100 indicates that the new password has been stored in the memory 30, and then ends the flowchart.

Here, the dial signal generator 80 inputs dial data output from the dial button 70 to generate a dial tone multi-frequency (DTMF) type dial signal to the DTMF detector 50 through the telephone line 40. Send it out. The DTMF detector 50 detects the DTMF signal from the output signal of the dial signal generator 80, converts the DTMF signal into hexadecimal data, and applies it to the microcomputer 60. The microcomputer 60 is output from the DTMF detector 50. The data is analyzed to determine the corresponding mode, and the data for displaying the function on the display unit 100 for the corresponding mode is sent to the driving unit 90. In addition, the above-described memory 30 is preferably configured as a nonvolatile memory to prevent the loss of data stored therein when the power is turned off.

As described above, in the multi-mode setting method and circuit of the multi-function telephone according to the present invention, the multi-mode is set using a dial button without operating a switch, so that the user can not only solve the inconvenience but also change the mode as the user desires. There is an advantage that can be set.
