Description

팩시밀리의 전송 방법 및 그 장치Fax transmission method and device thereof

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명에 따른 팩시밀리 장치의 개략적 회로도,2 is a schematic circuit diagram of a facsimile apparatus according to the present invention,

제3도는 본 발명에 따른 팩시밀리의 전송동작 프로우 챠트도.3 is a flow chart of a fax transmission operation according to the present invention.

Claims (2)

전송원고에서 독취되어 광전변환과 A/D 변환을 거친 데이타 신호를 압축시켜 두개의 라인 메모리에 순차적으로 저장하고, CPU의 신호에 따라 두개의 라인 메모리와 비교기를 인에이블시켜 비교기에서 두개의 라인 메모리에 저장된 신호를 비교하여, 같은 경우에는 선행라인 데이타를 송출하고 EQL 신호를 송출하며 라인 메모리(11)의 신호를 송출하고 라인 메모리(12)의 라인 데이타를 라인 메모리(11)에 이전하고 새로운라인 데이타를 라인 메모리(12)에 저장하여 상기와 같은 비교수순을 계속하여 두개의 라인 데이타가 다른 경우 선행 라인 데이타를 송출하고 라인 메모리(12)의 라인 데이타를 라인 메모리(11)에 이전하여 다음에 입력되는 라인 메모리(12)의 라인 데이타와 비교하여 철하도록 구성된 것을 특징으로하는 팩시밀리의 데이타 전송 방법.Compressed data signals read from the transmission document and subjected to photoelectric conversion and A / D conversion are sequentially stored in two line memories, and two line memories and comparators are enabled according to the CPU signal to enable two line memories. In the same case, the preceding line data is sent, the EQL signal is sent, the signal of the line memory 11 is sent, the line data of the line memory 12 is transferred to the line memory 11, and the new line is compared. By storing the data in the line memory 12 and continuing the comparison procedure as described above, if the two line data are different, the preceding line data is sent out, and the line data of the line memory 12 is transferred to the line memory 11, and then the next. A method for transferring data of a facsimile, characterized in that it is configured to be compared with line data of an input line memory (12). 원고를 독취하는 독취주사부(1)와 독취된 광신호를 전기적 신호로 변환하는 광전변화부(2)와 그 아나로그 신호를 데이타 처리 가능한 디지탈 신호로 변환하는 A/D변환부(3)와 데이타량을 감축하는대역압축부(4)와 CPU(6)와 모뎀(7)을 포함한 것에 있어서, 선행/후속 데이타 라인을 저장하는 두개의 라인 메모리(11)(12)와, 상기 두개의 라인메모리(11) (12)에 저장된 라인 데이타를 비교하는 비교기(13)를 포함하여 선행/후속 데이타를비교하여 전송시간을 축소하도록 구성된 것을 특징으로 하는 팩시밀리의 데이타 전송 장치.A read scanning unit 1 for reading an original, a photoelectric conversion unit 2 for converting the read optical signal into an electrical signal, and an A / D conversion unit 3 for converting the analog signal into a digital signal capable of data processing; Two line memories (11) (12) for storing the preceding and subsequent data lines, including the band compression section (4) for reducing the amount of data, the CPU (6), and the modem (7), and the two lines And a comparator (13) for comparing the line data stored in the memory (11) (12) to reduce the transmission time by comparing the preceding / following data. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
