Embodiment 1

[0131] The following description will explain the present invention based on the drawings showing Embodiment 1 of the present invention. FIG. 1 is a schematic front view of an image forming apparatus 100 according to Embodiment 1 of the present invention. In FIG. 1, 1 is a glass platen for placing originals thereon. Installed above the platen 1 is an automatic document feeding unit 2 including a document tray 20 and an image reading unit 24 described below. Installed below the platen 1 is a scanning unit 3 including an image reading unit 30 described below.

[0132] The image forming unit 4 is arranged below the scanning unit 3 such that a transport path 7 for discharging recording paper (paper) on which an output image is formed is located between the image forming unit 4 and the scanning unit 3 . The image forming unit 4 includes an electrophotographic processing section 40 , a fixing device 41 , an optical writing unit 42 , a process controller 43 for controlling the elec...

Embodiment 2

[0229] The following description will explain the present invention based on the drawings showing Embodiment 2 of the present invention. FIG. 20 is a schematic front view of an image forming apparatus 200 according to Embodiment 2 of the present invention. In FIG. 20, 101 is a platen glass for placing originals thereon. Installed above the platen 101 is an automatic document feeding unit 102 including an image reading unit (not shown) and a document tray 120 . Installed below the platen 101 is a scanning unit 103 including an image reading unit 130 .

[0230] The image forming unit 130 includes a scanning unit that moves in a reciprocating manner parallel to the lower surface of the platen 101 , a focusing lens, and a CCD linear sensor (none of which is shown) as a photoelectric conversion device. The scanning unit includes a light source for irradiating laser light to an original placed on the platen 101 or an original fed along a conveyance path, and a mirror for guiding l...

Abstract

An image on a fed document is read, and recording paper on which an output image is formed based on the read image is discharged onto a first tray. When overlapped feeding is detected at the time of feeding a document, page numbers of the overlapped documents are recorded, and an image on a document fed after the overlapped documents is read, an output image is formed on recording paper based on the read image, and the recording paper is discharged onto a second tray to notify the occurrence of overlapped feeding. When the documents are set again by the user and fed, an image on a document of a page number matching a recorded page number is read, an output image is formed on recording paper based on the read image, and the recording paper is discharged onto the first tray.

Description

technical field [0001] The present invention relates to an image forming apparatus and an image forming method capable of continuously forming images without stopping a document reading process when feeding a document, even when a plurality of pages of document are fed in an overlapping manner. [0002] The present invention also relates to an image forming apparatus and an image forming method capable of reducing the user's burden and continuously forming images even when sheets on which images are to be formed are fed in an overlapping manner. Background technique [0003] In recent years, an image forming apparatus such as a digital multifunction machine having a scanning function, a printing function, and a facsimile function includes an automatic document reading device, and passes a stack of documents placed on the document tray of the automatic document reading device to the image forming unit. A document is fed one page at a time, images recorded on the document are ...
