Abstract

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.

A device for processing a recording medium having a leading edge, comprising variable speed feed means for feeding the recording medium along a predetermined path with a preselected one of a plurality of speeds, means for recording a provisional record of a pattern on the recording medium being fed by said feed means, means forwardly along said path of said feeding means and said recording means for processing said provisional record into a final record of said pattern, store means between said processing means and one of said variable speed feed means and said recording means that is nearer to said processing means to be put normally in a first position for guiding the recording medium fed thereto by said variable speed feed means towards said processing means and controllably in a second position for storing the recording medium fed thereto by said variable speed feed means, controllable feed means for further feeding the stored recording medium to said processing means, and control means for controlling said store means and said controllable feed means, wherein:

said controllable feed means comprises a feed roller transversely of said path, a cooperating member put normally in a first location of disengaging with said roller and controllably in a second location of engaging therewith, and controllable drive means put controllably in a first mode of operation for making said feed roller feed at a predetermined speed the recording medium put between said feed roller and normally in a second mode of operation for rendering said feed roller to feed nothing;
said control means comprising detector means along said path at a predetermined distance from said feed roller for detecting passage thereby of the leading edge of the recording medium fed by said variable speed feed means to produce a start signal, first means responsive to said start signal for putting said cooperating member into said second location and said store means into said second position, second means for putting said controllable drive means into said first mode of operation a first predetermined interval after the last-mentioned leading edge reaches said feed roller, and third means for putting said cooperating member back into said first location, said store means back into said first position, and said controllable drive means back into said first mode of operation approximately a second predetermined interval after production of said start signal, said second predetermined interval being longer than said first predetermined interval.
