发明名称 ELECTROPHOTOGRAPHIC INFORMATION PRINTER WITH AUTOMATICAL DUPLEX SHEET PRINTING
摘要 PCT No. PCT/DK85/00096 Sec. 371 Date Jun. 24, 1986 Sec. 102(e) Date Jun. 24, 1986 PCT Filed Oct. 21, 1985 PCT Pub. No. WO86/02746 PCT Pub. Date May 9, 1986.In an electrophotographic information printer with a xerographic reproduction system automatic duplex printing of sheets is obtained without considerable reduction of the rate of operation in that a sheet (24) after having been discharged from a sheet supply (6, 7) is passed along a feeding path (9, 10) past an image transfer station (5) to a vertical reversing chamber (15) and therefrom fed back to the separate sheet magazine (6) having an inlet opening (23) for returned sheets positioned at the opposite end in relation to the sheet discharge opening (8). The reversing chamber (15) is integral with a sorting unit (14) in a common housing (13a), a selectively operable blocking member (19) and a reversing device (17), respectively, being disposed at the lower end of a vertical partition (40). In an electronically controlled information printer the operation is effected automatically in that character information is stored in a buffer memory having memory sections corresponding to print pages and, subsequently, after conversion into image information values said character information is stored in an image information memory from which the image information is read out to a scanning imaging device, the read-out from the buffer memory being effected by arbritary, selective addressing of the said memory sections and from the image information memory in order either forwards or backwards.
