Abstract: An image forming apparatus, comprises an image information receiving section to receive image information including image data and setting data indicating a control condition at the time of an image formation; a first storing section to store temporarily the image information received by the image information receiving section as one of a plurality of JOB data; an image forming section to form an image based on the image information stored in the first storing section; a second storing section to store image information corresponding to specific JOB data among the image information received by the image information receiving section; a selecting section to select JOB data to be combined from the plurality of JOB data stored in the second storing section; a judging section to judge the propriety of the JOB data selected by the selecting section based on the content of the setting data of the selected JOB data; and a control section to combine a plurality of JOB data judged as being selectable by the judging se

Abstract: An automatic document feeder includes a document stacker for holding documents, a first conveyer for feeding the documents one sheet by one sheet to a platen glass for reading an image on a first side of the conveyed document, a second conveyor for conveying the conveyed document so that the conveyed document is turned over and conveyed to the platen glass again to read an image on the second side, and a discharger for discharging the conveyed document from the platen glass and returning the conveyed document to the document stacker. A third conveyer, located over the platen glass, conveys the conveyed document from at least one of the first conveyor and the second conveyer to the platen glass and conveys the conveyed document from the platen glass to at least one of the first conveyer, the second conveyer, and the discharger.

Abstract: A method of indicating a setting screen of an image forming machine on which a touch-panel is displayed, wherein automatic setting conditions and a manual mode button are displayed on an initial screen; and when a touch operation is conducted on the manual mode button, a manual setting screen is indicated and an operating condition can be manually set by a touch operation on the manual setting screen.

Abstract: An automatic document conveying device has a stack tray on which a plurality of documents are stacked; a feeder by which the documents stacked on the stack tray are separated and fed one by one; at least one pair of conveying rollers provided downstream of the feeder; a reading position for reading document information from said separated documents positioned downstream of the at least one pair of conveying rollers; a conveyor provided opposite to the reader for conveying separated documents to the reading position; a discharger positioned downstream of said reading position for discharging documents after said conveyor conveys the documents to the reading position, a conveyance path on which a plurality of documents are sequentially located between the feeder and the reading position; the conveyance path having predetermined stand-by positions provided on the conveyance path at which documents, subsequent to a document positioned at the reading position are stopped; a document detector provided between the a

Abstract: 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.

Abstract: An apparatus with a document feeder for sequentially copying plural sheets of documents. When a document longer than a predetermined length is detected by a sensor, a stopper for aligning the document at a predetermined position is withdrawn in order to prevent the document from being damaged. At the same time, an indicator is turned on, warning the operator of jamming.

Abstract: An image processing apparatus includes a photoelectric converter, a multiple-value circuit, and a detachable external storage unit. The photoelectric converter photoelectrically coverts data of an original into image signals. The multiple-value circuit converts the image signals into multiple-valued data by comparing the image signals with predetermined threshold value data. The detachable external storage stores the threshold value data. The threshold values can also be made automatically responsive to gray scale data. The automatic mode and the manual selection mode are switched between in response to a release (toggle) signal. Color separation and color ghost correction are provided; and various types of formatting management are faciliated. Partial color converting (as, for example, color reversal) is also provided.
