Network system in which a plurality of image processing apparatuses are connected

An image forming system that does not impair the operability of a standardized external apparatus functions in a standard mode and an individual mode. The mode of the system is selected using a mode-switching switch on an operation unit or a work station. A display screen of the operation unit is switched in correspondence with the selected mode.

In order to raise the productivity of jobs to be output by an image forming apparatus, sheets belonging to a plurality of jobs that have been input are ejected in parallel in dependence upon the type of a sheet stacking apparatus connected to the image forming apparatus. Further, sheets belonging to a plurality of jobs that have been input are ejected in turns in dependence upon the status of use of a sheet stacking apparatus connected to the image forming apparatus. The sheet stacking apparatus is controlled in such a manner that sheets belonging to a plurality of jobs that have been input to the image forming apparatus can be ejected in parallel.

An output signal of an optical reading line sensor is converted into a digital signal by an A/D converter and, thereafter, is shading corrected by a shading correction circuit, and is inputted to a magnification processing circuit through a selector. An optical reading scanning speed by the line sensor can be freely changed. There are a first mode for zooming a read image by changing the scanning speed of the line sensor, a second mode for zooming the read image by the magnification processing circuit, and a third mode for commonly performing the zoom by changing the scanning speed of the line sensor and the zoom by the magnification processing circuit. Any one of the modes is adaptively selected in accordance with a size of original and a reading resolution.

In response to the setting of a first face-down mode on an operation panel, a topside pickup roller picks up documents stacked face-up in a document tray to bring the document to a document platen. In response to the setting of face-up mode on the operation panel, a bottom-side pickup semi-circular roller picks up documents stacked face-up in the document tray to bring the document to the document platen. A copying operation is now performed. In a single-side mode, recording sheets are inverted through a inverter path and then discharged in the face-down mode. Depending on the user's preference, the recording sheets are discharged face-down or face-up. In either discharge mode, the order of pages of copied recording sheets is not reversed.

A copying apparatus includes an original feed unit for feeding originals stacked on the stacking position to an exposure position one by one, an exposure unit for exposing an image on the original fed to the exposure position, and an image forming unit for forming the image exposed by the exposure unit onto a sheet, the image forming unit being able to operate in a first mode for forming an image on a single original on a single sheet, and a second mode for forming images on a plurality of originals on a single sheet. The original feed unit includes a first feed unit for feeding the originals stacked at the stacking position in turn from the last page, and a second feed unit for feeding the originals stacked at the stacking position in turn from the first page. When the image forming unit operates in the first mode, the first feed unit feeds the originals. When the image forming unit operates in the second mode, the second feed unit feeds the originals.

An image processing apparatus has an adjusting mode which enables determination of a magnification correction value. A predetermined image on a test chart placed on an original table or an image of a chart fixed outside the valid image area are read, and the proper correction value for compensating for any variation in the image magnitude within a scanning system is computed based on the results of reading the test chart image. Subsequently, a printing system is operated to print test chart data read from a memory and the image printed in accordance with the test chart data is read by the scanner system which has been corrected, the result of the reading being used in computing the magnification correction value for compensating for any magnification variation occurring in the printer system.

When images on the front and rear sides of multiple originals are reduced in size and recorded onto both sides of a single recording sheet in composite form, recording positions of images on the front and rear sides of each original are determined such that reduced images on the front side of the original are recorded on the front side of the recording sheet and reduced images on the rear side of the same original are recorded at corresponding positions on the rear side of the recording sheet. As a result, when the recording sheet is cut into pieces corresponding to respective recorded images, images on the front and rear sides of each cut piece of the recording sheet respectively agree with images on the front and rear sides of each original.
