The ring detector 116 is connected to the switching output terminals bl and b2 and the switching output terminals a3 and a4 of the first relay 102 in parallel to each other so that the first telephone lines L1 and L2 and the second telephone line are connected in parallel. Detects and outputs ring signals received through telephone lines L3 and L4. By the above connection, the connection structure of one facsimile device and one telephone as shown in FIG. 1 is made through the relay element.

2 is a block diagram of a facsimile apparatus applied to the present invention, wherein the CPU 10 controls the telephone function and the fax function to be used simultaneously when two lines are connected according to a predetermined program. kl) and various display control data. OPE (OPERATING PANNIL) 20 has a plurality of keys for selecting various functions, inputs them to the CPU 10 when the key data is generated, and displays data under the control of the CPU 10. The memory unit 30 accesses or stores data under the control of the CPU 10 and a program for making two telephone lines available at the same time. The scanner 40 scans an image of an original and provides it to the CPU 10 as digital image data. Under the control of the CPU 10, the modem 50 performs analog modulation on the transmission data and demodulates the analog reception data. The network control unit (NCU) 60 is operated under the control of the CPU 10 to form a call loop of a telephone line, and interfaces a signal of the modem 50 with a signal of the telephone line. The printer 70 prints an image on a recording sheet under the control of the CPU 10.

The facsimile apparatus according to the present invention having the relay connection structure of FIG. 1 and the configuration of FIG. 2 performs a control flow according to FIG. 3 to achieve the above object.

3 is a control flow diagram for connecting two trunk lines according to the present invention and simultaneously using a telephone and facsimile data.

Here, FIG. 3 allows a facsimile operation to be performed on one line when there is one telephone and one facsimile device of the present invention. That is, the present invention describes a method of transmitting / receiving facsimile data to and from another telephone line while the user is making a phone call using the facsimile telephone through one telephone line.

Referring to FIG. 3, in step 201, the controller 10 determines whether a ring signal is detected from the first-second ring detection circuits 108 and 116, and if no ring signal is detected, the controller 10 proceeds to step 202. In step 202, the controller 10 checks whether the handset of the telephone is hooked off from the hookoff detection circuit 112. If not, the controller 10 proceeds to step 203. In step 203, the controller 10 checks whether an original is fed from a document detection sensor (not shown). If the original is not fed, the control unit 10 returns to step 201. If the original is fed, the controller 10 proceeds to step 217. In step 217, if the on-hook dial key is input, the control unit 10 checks whether the first telephone lines L1 and L2 are in use in step 218. In step 219, the controller 10 inputs a dialing number input by the user from the OPE 20, performs dialing, and proceeds to step 220. In step 220, the controller 10 inputs a start key input from the OPE 20 to transmit the image data scanned from the scanner 40 to the telephone line through the modem 50 and the NCU 60. When the image data transmission is completed, the controller 10 terminates communication in step 221 and outputs the CML signal in a low state and returns to step 201. When the CML signal is output in the low state, the second relay 108 has a switching input terminal c5-c6 connected to the switching output terminal a5-a6.

However, if the first telephone lines L1 and L2 are in use in step 218, the control unit 10 connects the second telephone lines L3 and L4 in step 222. In step 223, the controller 10 opens the OPE ( In step 20), the user dials a dialing number input by the user, and proceeds to step 224. In step 224, the controller 10 inputs a start key input from the OPE 20 to transmit the image data scanned from the scanner 40 to the telephone line through the modem 50 and the NCU 60. When the image data transmission is completed, the controller 10 ends the communication in step 225 and outputs the CML signal in a low state, and returns to step 201.

On the other hand, if the hook is off in step 202, the off-hook flag is set to 1 in step 204, and the process proceeds to step 205. In step 205, the control unit 10 checks whether the first telephone line L1, L2 is in use, and if the first telephone line L1, L2 is in use, the CML signal becomes high and the first telephone line is faxed. In step 209, the controller 10 performs dialing by inputting a dialing number input by the user from the OPE 20 through the second telephone lines L3 and L4. When the telephone call is terminated in step 210, the controller 10 resets the on-hook flag to 0 in step 211 and returns to step 201. However, if the first telephone lines L1 and L2 are not in use in step 205, the controller 10 proceeds to step 206 in which the controller 10 inputs a dialing number input by the user from the OPE 20 to dial and form a call. . After the call is formed, the control unit 10 checks whether the fax communication is performed in step 208, and proceeds to step 212 if the fax communication is carried out. In step 213, when the control unit 10 inputs the start key input from the OPE 20, the control unit 10 resets the on-hook flag to 0 and proceeds to step 215 to transfer the image data scanned from the scanner 40 to the modem 50 and It communicates by sending out to the telephone line through the NCU (60). After the image data transmission is completed, the flow advances to step 216 to terminate the communication, outputs the CML signal low, and returns to step 201.

If the ring signal is received in step 201, the ring signal is detected in step 226. In step 227, the ring signal is detected from the first telephone line or the second telephone line. At this time, if a ring signal is detected from the first telephone line, in step 229, the controller 10 checks whether the automatic reception mode is set. If the ring signal is set in the automatic reception mode, the controller 10 proceeds to step 230. In step 230, the control unit 10 proceeds to step 231 when the set number is counted by counting the ring counter. In step 231, the controller 10 generates a high signal from the CML signal. Then, the input terminal (c5, c6) and the output terminal (b5, b6) of the second relay 106 is connected, so the fax communication starts in step 232 to receive the image data, and when the communication ends, the control unit 10 in step 233 Outputs the CML signal low. However, if it is set to the manual reception mode instead of the automatic reception mode in step 229, the flow proceeds to step 234 to drive a speaker (not shown) to generate ringing sounds. If the hook-off switch is detected in step 235, and the hook-off state is detected from the hook-off detection circuit 112, the hook-off flag is set to 1 and the process proceeds to step 236. If it is not in the fax communication mode, the process proceeds to step 237, the telephone call is made, and the process proceeds to step 238. In step 238, when the telephone call is terminated, the controller 10 resets the hook-off flag to '0' in step 239 and returns to step 201. However, in step 236, if it is in the fax mode, the controller 10 proceeds to step 240 and the controller 10 inputs a start key input by the user from the OPE 20 and proceeds to step 241. Occurs with a high signal. Then, the input terminals c5 and c6 of the second relay 106 and the output terminals b5 and b6 are connected. At this time, in step 242, the control unit 10 hooks the telephone 114, clears the hook-off flag to 0, starts a fax communication in step 243, receives image data, and when the communication ends, in step 244, the control unit 10 Output the CML signal low.

In addition, if a ring signal is detected from the second telephone line in step 227, the controller 10 determines whether the first telephone lines L1 and L2 are in a call in step 245. Ring through the signal and proceed to step 247. If the hand cell is lifted off-hook by the user in step 247, the hook-off flag is set to 1, the phone call is made in step 248, and the process proceeds to step 249. When the telephone call is terminated in step 249, the controller 10 resets the on-hook flag to 0 in step 211, and returns to step 201.

However, if the first telephone line (Ll, L2) is busy in step 245, the process proceeds to step 251. The hand cell is lifted by the user and sets the off-hook re-hook hook-off flag to 1 and performs a phone call in step 252. Proceed to step. In step 253, the control unit 10 checks whether the fax communication is performed. If not, the control unit 10 proceeds to step 249. If the fax communication is performed, the control unit 10 proceeds to step 254. The control unit 10 inputs a start key input from the OPE 20. In step 255, the line select signal LINE SELECTS is generated high and applied to the first relay 102. Then, the first terminal 102 is connected to the input terminal (c3, c4) and the output terminal (b3, b4) is connected to the fax modem part 110. At this time, in step 257, the control unit 10 hooks on the telephone 114, clears the hook-off flag to 0, starts fax communication, and receives image data. Then, when the image data reception ends, the controller 10 ends the communication in step 258 and generates a line select signal LINE SELECT low, and returns to step 201.

According to the present invention as described above, the facsimile having the telephone integrally has a plurality of telephone line access functions, thereby facilitating transmission and reception of facsimile data during a telephone call using the facsimile telephone.

Although the above-described invention has been described and limited by way of example with reference to the drawings, the same will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention.
