摘要:
An original image comprises a printed region on which a predetermined printed matter is realized and a background region on which no printed matter is realized. The shape of a peripheral zone in the original image comprises the shape of the background region, which shape exists particularly at the peripheral region of said original image. It is determined whether or not the original image comprises the special document by detecting the peripheral zone. Further, the original image has an outer-frame region, having a predetermined shape, at the peripheral region of the original image. The determination is carried out using a result of measuring the width of the outer-frame region. Further, the width of the outer-frame region comprises a width along a direction substantially perpendicular to a direction extending along the outline of the original image.

摘要:
The present invention relates to a special-document discriminating apparatus used for providing a counterfeit preventing function to a digital copy machine and the like, and to a managing system for an image forming apparatus having a special-document discriminating function. The special-document discriminating apparatus is provided with a ROM for discriminating a special-document such as paper money, which ROM is detachably attached to a controlling circuit board. Data used for determination may be learned from test pattern data input from the image forming apparatus, or the data may be input from an external unit via a communication line. The managing system for an image forming apparatus comprises an image forming apparatus and a managing apparatus connected to the image forming apparatus. Either the image forming apparatus or the managing apparatus has a special-document discriminating function. Additional information is sent from the image forming apparatus together with determination result information or detected data. Information used as reference for determination may be sent from the managing apparatus to the image forming apparatus.

A desktop color copier having a size which allows the copier to be placed on a stand when the copier is used. The desktop color copier includes a photoconductive drum for sequentially forming toner images of respective colors thereon, a charger for charging the photoconductive drum, an exposure device for exposing the charged photoconductive drum, a revolving type developing device for forming color toner images on the photoconductive drum, an image transferring devices which includes an intermediate transfer belt to which the color toner images are sequentially transferred one on top of the other, and a fixing device for fixing the color toner images on a sheet of paper. The desktop color copier includes a single paper feed tray which is located under the transferring devices.
摘要:
A color image forming apparatus is provided with a printer controller which is capable of receiving color image data for one page, which is divided into a plurality of data for each of a corresponding plurality of colors, at an irregular interval, and, upon receiving the image data for one color, driving an image forming device to form an image of the color whose data has been received, and after images of all of the plurality of colors are completed, outputting the final image on a recording media. The image forming device may also include, an intermediate image transfer belt for forming thereupon an image of each of the plurality of colors, superposing one on another, and a leading edge detect sensor to detect a leading edge of an image of each of the plurality of colors for registering the leading edges of images of the plurality of colors. The apparatus may further include, in addition to a scanner and a printer, a system controller which issues an image formation command for each of the plurality of colors to the scanner and the printer at a regular interval in a copy mode, and to the printer at an irregular interval in a print mode.
摘要:
A digital color copying machine preparing an image reproducing copy by applying color separation to an original image of an original and processing color component signals for each of the separated colors into recording information. With such a digital signal processing, the color copying machine of the present invention can increase the speed and efficiency of multiple copies and can provide a symmetric copy mode, a swap or inverting copy mode and a multiple image copy mode.
摘要:
A modular copying system including combinations of printer, scanner, and system controller modules formed as independent frames. The scanner module includes devices for image reading, first data I/O and first synchronizing signal generation; the printer module includes devices for image forming, second data I/O and second synchronizing signal generation; and the system control module includes devices for third data I/O and system control. The modules are added or removed according to user requirements and the system is capable of accommodating up to seven modules. The modules are stacked in a vertical direction and arranging devices ensure proper module alignment. Once the modules are aligned and assembled in the system, communications between each module is accomplished via light wave, electric wave, or sonic wave transmission and reception. As a result, system interconnection is reduced, system noise is reduced and various connecting cables are eliminated. In addition, the system can be connected to a public ISDN line for transmitting detected system faults to the factory and for receiving fault diagnosis information which is displayed to a user via a display. Further, the system is capable of performing various image processing functions, such as processing with a space filter, image size conversion, image-trimming, image movement, color image trimming, color correction, and tone conversion.
