Copy discouraging information which is used for prohibiting or discouraging copying of image information is formed so that it can be positively recognized by a copy machine. The copy discouraging information which is used for prohibiting or discouraging copying is printed so that the number, position and shape of the items of the copy discouraging information are made different depending upon the importance degree of the image information to be printed. If the image information has, for example, a relatively higher importance degree, a plurality of items of the copy discouraging information are printed in the inner sides and in the vicinity of four sides of recording paper. When someone tries to copy this recording paper by the copy machine, presence of the copy discouraging information can be immediately recognized in the copy machine regardless of the scanning direction.

There are at least four patterns of mounting the original on which an original image including a predetermined image marking “SECRET” indicating the content is confidential information, in an original mounting unit such as an ADF. The image processing apparatus generates image data expressing the image depending on the original mounted state, and four pattern images are obtained depending on the direction of mounting the original. Of the plural original mounted states corresponding to plural layout states such as position or direction of the predetermined image, the predetermined mounted state of the original permitting image processing is preliminarily noticed to an authorized user, and image processing is prohibited when the layout state of the predetermined image corresponding to other mounted state than the predetermined mounted state is given, so that image processing by unauthorized user can be prevented.

The present invention is directed to the provision of an image forming apparatus capable of effectively preventing the formation of images related to illegal conducts by making provisions so that, even in situations where images can be formed based on image data outputted from any arbitrary image output apparatus, the image output apparatus which outputted the image data can be identified without fail. When image data is inputted from a portable image output apparatus, first it is checked whether identification information has been inputted together with the image data, then an image of an identification pattern is created, and image formation is performed based on image data obtained by attaching the image data of the identification pattern to the input image data. On the other hand, when image data is inputted from a fixed image output apparatus, first it is checked whether identification pattern data is included in a designated position in the image data, and then image formation is performed based on the input image data. The image thus formed by the digital copying machine contains the image of the identification pattern by which the image supply device that outputted the source image data is identified.

During warming up such as carried out upon power application, a first or second condition managing section monitors the status of an always changing device such as an image station and a fixing device, and based upon the current status of the device and the features of data for print jobs that have been received, a control section determines the order of the jobs to be printed out and carries out the corresponding output. Therefore, it is possible to efficiently output images without delay in handling image data even during warming up upon power application.

In conventional color digital copy machines, when copying in color mode, the polygon mirror of the laser beam scanner for black, which is driven at a higher speed than those of the other colors, is switched to a slower speed in conformity with the speed of the polygon mirrors for the other colors. However, a drawback of this structure is that, especially when switching from monochrome to color mode, the time required to obtain the first copy is lengthened, and the operating efficiency of copying is poor. In the present invention, when copying in color mode, the rotation speed of the polygon mirror of the laser scanner unit for black is not changed at all, but, by skipping certain mirror surfaces of the polygon mirror, and/or by skipping certain of a plurality of laser light sources, the scanning density of the laser scanner unit for black can be brought into conformity with that of the laser scanner units for the other colors.

An object of the present invention is to offer an image stabilizer device capable of effectively improving quality of images produced by an image forming apparatus of a type that changes the size of a basic pixel by controlling an irradiation time of write-in light, and to offer a pattern image reader device used for the purpose. A pattern image reader device 100 is constituted by a reader unit 2 that at least contains a semiconductor laser 3, converging lens 6, and photosensor 5 for reading the amount of reflected light, and the driving section 7 that contains a drive coil 7c for moving the reader unit 2 in the principal scanning direction, and can measure on the order of microns the size of a toner image formed on the surface of a transfer and transport belt 26 in the principal scanning direction by monitoring the output of the photosensor 5 while moving in the principal scanning direction under the control by the CPU 48. The CPU 48 thereafter corrects lookup tables 45a to 45d according to the dot diameter measured in the principal scanning direction.
摘要:
An image-forming system is constituted by connecting a plurality of digital copying machines to a communication apparatus so that the digital copying machines can transmit and receive image information with each other. As an instruction for image processing is inputted at any of the digital copying machines, a control section of the digital copying machine outputs the image information to a digital copying machine that is capable of carrying out the image processing. The digital copying machine that is assigned the image processing carries out a predetermined image processing on the image information and returns the processed image information via the communication apparatus. The image information is then visualized by a digital copying machine that receives the image information. Therefore, even if a predetermined image-processing function cannot be found in the digital copying machine that is to be used, the image information is processed by another digital copying machine having that image-processing function. This reduces economic burden on the user of the digital copying machine.

In the present image forming system, when a digital copying machine having no specimen image judging section makes a copy, it transfers an input image to an image processing apparatus having the specimen image judging section within the system to request to judge whether the input image is a copy-prohibited image on its behalf. When the judging result is returned within a predetermined period, the digital copying machine controls the copying operation based on the judging result: when the judging result is negative, a normal copying operation is carried out; when the copying is totally prohibited, the image processing apparatus ends the copying operation after informing the user that the copying operation is terminated because the copying of the subject image is prohibited. Consequently, whether the subject image data are a specimen image like paper money can be discovered at the image processing machine, thereby preventing a crime, such as forgery of paper money or securities. Also, if the specimen image judging section is installed in the image processing apparatus, each digital copying machine connected to the same does not have to include the specimen image judging section, thereby suppressing a cost increase.
摘要:
An image forming system is arranged such that when a designated machine is not provided with the image processing function requested by an operator, a plurality of image forming apparatuses which are capable of performing the requested image processing function are selected. Then, the image data are respectively transferred to the selected plurality of image forming apparatuses through a transmission apparatus to be processed. When the image data has been processed with a requested image processing function, the processed image data are returned to the image forming apparatus of the requesting end. Then, the image forming apparatus of the requesting end realigns a plurality of processed image data. As a result, even if a predetermined processing function is not provided in the designated image forming apparatus, a plurality of image data are transmitted to other image forming apparatus to be processed, thereby obtaining a visible image efficiently.
