The first embodiment of the present invention relates to a shared fax information transmission unit in which one fax transmits data coming from three external terminals.

Next, as shown in FIG. 1, the shared fax according to the first embodiment of the present invention has a port section including a first port stage 20, a second port stage 21, and a third port stage 22 into which external data is input. And receiving data from each port of the port portion, and receiving the received data from the first signal of the first parallel sequential FIFO unit 23, the second signal of the second parallel sequential FIFO unit 24, and the third parallel sequential FIFO. If only one of the three signals coming into the parallel control FIFO section and the first control means section 26 which is sent to the first control means section 26 in the form of the third signal of the section 25 is high, A high priority prioritization register (28) which operates only the parallel sequential FIFO unit which has become high) and controls two or more highs at the same time to operate the parallel sequential FIFO unit having a high priority first. By controlling the operation time of the control means 26, one parallel sequential FIF only for a specified time And a timer 27 for transmitting the data of the O portion to the fax memory portion 29.

Subsequently, as shown in FIG. 2 showing the configuration of the parallel sequential FIFO unit of the present invention, the parallel sequential FIFO unit transmits a start signal to the first control unit 26 when data is input from each port. And FIFO memory section 36 and FIFO which store data such as status register 32 which stores states such as start and stop of data received from each port and parity error, and parallel sequential FIFO section. The FIFO register 33 that records the amount of data to be stored in the memory unit 36 and the shift register 34 that receives data continuously and converts the data into a parallel form in a single byte and sends the data to the buffer register 35. Receives data from the buffer register 35 and the FIFO memory section 35, which transfers the data received from the shift register 34 to the FIFO memory section 36, and receives the fax control section and the fax. And a data bus buffer unit 37 for transferring to the memory unit 29, and a second control means unit 30 for controlling each component inside the parallel sequential FIFO unit.

Next, the information transmission method of the shared fax of the present invention uses the external terminal of the first port terminal 20, the second port terminal 21, and the third port terminal 22 as shown in FIGS. 1 and 2. Data input to the first parallel sequential FIFO section 23, the second parallel sequential FIFO section 24, and the third parallel sequential FIFO section 25, and the receiver timing controller 31 in each parallel sequential FIFO section. Generating each of the first signal, the second signal, and the third signal to the first control means section 26; and controlling the first signal, the second signal, and the third signals from each parallel sequential FIFO section. Determining a parallel sequential FIFO unit to be operated first through the means unit 26; sending a corresponding first stop signal, second stop signal, or third stop signal to the parallel sequential FIFO unit not selected for the line operation; The parallel sequential FIFO section selected according to the line operation determines the received data. After the step of transmitting to the fax memory unit 29 until the time of the timer 27 is completed and the storing of the data in the parallel sequential FIFO unit in the fax memory unit 29 are finished, the first control means unit 26 receives the fax control unit ( 29) and the fax control unit 29 operates to generate a tag after the last data stored in the fax memory unit 29 before being interrupted. In determining the parallel sequential FIFO unit to be operated first among the above-described operations, when two or more of the first signal, the second signal, and the third signal that have entered the first control unit 26 are high, a priority determination register ( 28, the first control means 26 is controlled to select the parallel sequential FIFO to operate first.
