摘要： A multi-functional copying machine according to the invention has a scanner for reading the image of a document and image information appended to the document and a printer for forming the image on a medium. It compares the image read by the scanner and the image information, determines according to the extent of alteration of the image whether or not reproduction of the image of the document as it is can be permitted and, if permitted, produces a copy from the reproduced image of the document. If reproduction is forbidden of the image of the document as it is, whether or not to permit restoration of the scanner-read image according to the image information is determined and, if permitted, a copy is produced from the restored image. This makes it possible to keep track of any alteration in a copyrighted image by quick processing, prevent altered copyrighted images from circulation, and protect copyrighted images appropriately.

摘要： An apparatus and method for eliminating position deviations of a photosensitive drum which is rotated by a stepping motor driven by full step and half step drive pulses. The apparatus includes a photosensitive drum, a stepping motor which rotates the photosensitive drum; and a controller which controls the stepping motor to be driven with half step drive pulses when the photosensitive drum is being scanned. In the apparatus and method, a scanning starting control is performed by driving the stepping motor by full step drive pulses so that salient poles of the rotor are aligned with salient poles of the stator such that the rotor is in a stable position. The full step drive pulses are switched to half step drive pulses before scanning is started, and the scanning of the photosensitive drum is started on an even numbered half step drive pulse.

摘要： An image copying device and an image copying system are arranged to read an image of a document and to acquire copyright information on each area regarding the image of the document from an IC chip embedded in the document. Then, based on the read image data and the acquired copyright information, a selection screen is displayed on a manipulation/display panel. Copyright information on each area of the image of the document is schematically represented on the selection screen. Whether or not copying is performed is selected area by area by manipulation by a user on this screen. For areas for which “copying” is selected is copied, but areas for which “nocopying” has been selected is not copied. Further, a copyright fee pertaining to the copied areas is collected. Thus, the image copying device and an image copying system enable the user to select appropriate processing according to differences in copyright information from one area to another of the image and cause images to be formed.
