摘要： In a facsimile receiver comprising a recording unit for forming a latent image on a continuous recording medium fed by a variable speed feed unit and a developing and fixing unit for processing the latent image into a visible one, a controllable feed unit and a store unit are arranged successively prior to the processing unit. When fed to the controllable feed unit by the variable speed feed unit, the continuous sheet is held by the former so as to heap in the store unit. Responsive to a page end signal, a cutter disposed prior to the store unit cuts the continuous sheet into a separate sheet and a remaining continuous sheet. The separate sheet is now fed by the controllable feed unit to the processing unit at a predetermined speed. The recording medium may be one of stacked separate sheets, when the controllable feed unit feeds the above-mentioned one separate sheet a predetermined interval after the separate sheet is fed thereto by the variable speed feed unit. This invention is applicable also to a device where a provisional record of a pattern formed on a recording medium fed with a preselected one of various speeds should be processed into a final record with the medium fed at a predetermined speed.

摘要： In order to increase decoding speed of two-dimensionally encoded facsimile data, changing pixels a.sub.0, a.sub.1, a.sub.2 and b.sub.1 (defined by CCITT) on a decoding and reference lines are detected, and the address of b.sub.1 is stored into a reference line address memory. The address of b.sub.1 is compared with the address of a.sub.1 during the vertical mode, and if a.sub.1 >b.sub.1, the address of a.sub.1 is stored into the reference line address memory. During the horizontal mode, the addresses of b.sub.1 and a.sub.2 are compared. If a.sub.2 >b.sub.1, the address of a.sub.2 is stored into the reference line address memory.

摘要： A digital facsimile system provides band-compression of half-tone picture signals. Primarily, a plurality of analog signals are derived by successively scanning a picture. Thereafter, the analog signals are converted into digital signals and then the digital signals are compressed. Initially, the digital signals are pulse trains of two-level signals, representing the scanned picture, sliced into segments at multi-level quantization levels. Band compression is realized after a plurality of two-level digital pulse trains are compared. Only the differences between corresponding bits, which are found by the comparison, are encoded and transmitted.

摘要： In a facsimile receiver, a reversible pulse motor feeds a continuous recording medium forwardly during recording, further forwardly to a cutter after the recording, and backwardly after cutting from the continuous recording medium by the cutter of a separate sheet on which a figure, namely, a picture or its equivalent, is recorded. During the recording, clock pulses may be counted by a counter and supplied in groups to the pulse motor to stepwise feed the recording medium. The amount of the further feed should not be less than that of the backward feed. Preferably, these amounts are determined by two counters energized when the recording ends and when the cutter works, respectively, to count the clock pulses to predetermined counts. Alternatively, a single counter is similarly energized to count the clock pulses to a predetermined count so as to render the amounts equal. The clock pulses to be counted for the further and the backward feed may have a higher repetition frequency than the pulses for the stepwise feed. The cutter may work as soon as the counter counts the clock pulses to the predetermined count for the further feed.
