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.

Image forming apparatus and image forming method

A charging system includes a plurality of image forming apparatuses, and an information processing device that manages a charging processing on the image forming apparatus. The image forming apparatus detects a trouble occurring on the image forming apparatus, and transmits a total number of output papers put out of the image forming apparatus and the detected contents of trouble to the information processing device as a use condition of the image forming apparatus. The information processing device calculates a total amount of service charge on the basis of the total number of output papers transmitted from the image forming apparatus, and also calculates an amount of deduction corresponding to the contents of trouble transmitted from the image forming apparatus. The information processing device deducts the amount of deduction from the total amount of service charge to calculate an amount of charge on the image forming apparatus.

An image processing portion for conducting the specified processing of an image to be reproduced by an image forming portion based on the processed image data is constructed as a single control portion. Consequently, the development of a variety of digital copying machines requires preparation of specially designated control boards according to levels of the products. This makes machines expensive and requires users to pay a considerable initial cost. An image processing device of the present invention is provided with an image information inputting means for inputting image information as a first level image, a main image-processing board for conducting the specified processing of the input image information of the first revel image, a sub image-processing board for conducting the specified processing of the image information processed by the main image processing board and outputting the information as a second level image, and a means for reproducing an image according to the image information processed by the main image-processing board or the sub image-processing board. These boards are independent from each other in the circuit configuration.

A network system for copiers includes a plurality of copiers each provided with a communication device for communicating with external equipment and a power-on device for powering on the copier in a hold state in response to an external signal received by the communication device and a main controller including an operation controller for controlling operation of the copiers and a time setter for setting time to power on a copier, the main controller being connected to the copiers by a network. The operation controller executes control such that only predetermined one of the copiers is powered on at the power-on time set by the time setter.

A document platen driving device is provided with an endless gear connected to a document platen, whereon a document is placed, which reciprocates. A sun gear is secured to a fixed station within a space surrounded by the endless rack, and a planetary gear meshing with the endless rack and with the sun gear is also provided within the space. The planetary gear is a double gear composed of a large gear and a small gear having different pitch circle diameters. It is arranged such that the document platen is moved forward by meshing the small gear with the endless rack, and moved backward by meshing the large gear with the endless rack. In this arrangement, the backward moving speed of the document platen can be set faster than the forward moving speed, thereby permitting a reduction of the entire time required for a copying process, especially for a successive copying process.
