The flow process of Fig. 6 comprises the following steps: when the sending start signal is produced, detect whether there are more than two situations of sending the starting signal; check the circuit of detecting the sending signal, thereby print the video data corresponding to the lower line sequence number and store Corresponding to the video data of other line numbers.

The following description will be made with reference to the block diagram in FIG. 1 and the flowcharts in FIGS. 2 and 3 .

The operation of the process for receiving video data from several facsimile systems enables the transfer of received video signals to dedicated facsimile devices. In step 150, the central processing unit (CPU) 30 detects whether a telephone ring signal comes from the public telephone network. In step 160, at this time the CPU 30 controls the corresponding components so as to form a call path. Then in step 170, the CPU 30 detects whether there is a calling tone (CNG) signal. At this time, if a CNG signal is detected, the CPU 30 controls the corresponding components to switch to the receiving mode. Then the CPU 30 controls the printing control 60 to send a sending start signal, so that in step 210, the received data is sent to the dedicated printing device. In step 220, the CPU 30 detects the sending end signal; at this time, if the sending end signal is detected, the CPU 30 sends the sending end signal to the dedicated printing device 20 in step 230 .

On the other hand, for the case where the CNG signal is not detected in step 170, the CPU 30 controls the corresponding components to perform a general telephone call in step 180. In step 190, the CPU 30 detects the received information. At this time, if the received information is detected, then in step 200, it will switch to the receiving mode. After steps 210 to 230 are executed, the program ends accordingly.

The following describes a flowchart in which received data transmitted when received data is transmitted from the facsimile system 10 in the same manner as described above is received and printed.

In step 240, CPU 100 detects a transmission start signal. Then in step 250, the CPU 100 checks the flag. At this moment, the signs show the corresponding states of the telephone lines connected from the facsimile system 10, as shown in FIG. In the format of the marks, "0" on the first one on the right indicates that the first facsimile system is in a waiting state, and "1" indicates that video data is in the process of being transmitted from the first facsimile machine. Then, in step 260, the CPU 100 detects whether the dedicated printing device 20 is in the process of printing. At this time, if the dedicated printing device 20 is not in the printing process, the CPU 100 generates and sends a control signal to the printer 140, so that in step 280, the sent data is printed in the order of a priority order. While the dedicated printing apparatus 20 is during printing, in step 270 the CPU 100 stores the transmitted data in the memory in the order of a priority command. At this time, the storage area of the memory 120 is as shown in FIG. 5 . Subsequently, in step 290, the CPU 100 checks whether or not the facsimile system 10 generates a transmission end signal. At this time, if a transmission end signal is generated, in step 300, the CPU 100 detects whether the dedicated printing device 20 is in the process of printing. At this time, if the dedicated printing device 20 is not in the printing process, the dedicated printing device 20 prints data in the order of priority instructions stored in the memory 120 . At this time, in step 310 of judging the priority command, the CPU 100 detects whether there is a transmission start signal. If the transmission start signal is detected, it is checked by the CPU 100 at step 320 whether there are transmission start signals of more than two facsimile systems. If only one transmission start signal of the facsimile system is detected, then in step 340, the CPU 100 prints the received data of the line transmission with the transmission start signal. On the other hand, if transmission start signals of more than two facsimile systems are detected, the telephone line having the transmission start signal is checked in step 330 . Thereafter, in step 350, the CPU 100 compares the A telephone line number with the B line number, thereby checking whether the B telephone line number is higher than the A line number. Here, the A line number and the B line number refer to the numbers of the connection lines from the two facsimile systems to the dedicated printing apparatus 20 . At this time, in step 350, if the sequence number of line B is higher than that of line A, then in step 360, the received data of line A is printed. On the other hand, if the serial number of the A line is relatively high, then in step 370, store the received data of the B line in the memory.

In step 370, CPU 100 stores the received data, and then executes step 380. At step 380 , CPU 100 checks whether the printing of the received data of line A has been completed, and if the printing is completed, the program proceeds to step 390 . Otherwise, the program goes to step 360 . In step 390, the CPU 100 prints the received data of the B line stored in the memory, and then ends the routine.

The method of collectively receiving video data according to the present invention has the following advantages: by providing efficient document handling to several operating facsimile systems when the received video data is sent to a dedicated printer and the sent video data is printed in a dedicated printing device, it is possible to The lower cost sets up a dedicated sending fax machine and saves users from having to wait indefinitely while the fax system is in operation.
