摘要： In a sorting machine designed for use with a copying machine capable of handling paper of various sizes, a vertical array of sorting bins includes an uppermost sorting bin with an expandable surface area. This allows the sorting machine to handle extraordinarily large paper without increasing the footprint of the sorting machine. The uppermost position ensures that when expanded, the expandable sorting bin will stand over the copying machine, which does not normally need great overhead clearance. The expandable sorting bin may be expandable by virtue of a hinged, sliding or detachable extension plate, and may be expanded automatically when the copying machine detects and signals the use of larger paper. Multiple expandable sorting bins may be used for sorting the extra-large paper. In addition, the sorting machine may have one normal-sized sorting bin in alignment with a main receiving tray of the copying machine so as to allow the main tray to accommodate extra-large paper.

摘要： A paper discharge apparatus for a recording system includes a plurality of vertically movable bins, arranged vertically stepwise, for receiving a recorded sheet discharged from a recording system main body, a lifting mechanism, a shifting unit, and a selection shift selecting unit, and a shift operation control unit. The lifting mechanism moves the bins upward/downward stepwise in synchronism with a sheet discharging operation in a sort mode. The shifting unit transversely shifts a discharging direction of a recorded sheet from a normal discharging direction. The selection shift selecting unit selects a shift mode or a non-shift mode as a discharge mode. The shift operation control unit operates the shifting unit such that when a number of sets of recorded sheets more than the number of bins are to be discharged in the sort mode, sets of recorded sheets discharged exceeding the number of bins are shifted and discharged in a reverse order from the lowermost bin or the uppermost bin, and recorded sheets for the next original are shifted and discharged from the last used bin of an immediately preceding original to the lowermost or uppermost bin and discharged without shifting to the first bin thereafter.

摘要： An electrophotographic copying apparatus has increased speed in recording sheet conveyance where the conveying path from the sheet feed cassette to the photosensitive member is relatively long. The sheet conveyance apparatus is constructed to equalize the line speed of the photosensitive member, the feed speed of the recording sheet and the conveying speed of the recording sheet. A plurality of sheets serially fed out from a sheet tray are concurrently transported along the sheet path. A sheet is fed out from the sheet tray in response to a timing reference signal generated in response to the scanning operation for a previously fed out sheet.
