摘要:
A copying machine which has a function to contain sheets, each of which has an image on a first side, in a refeeding unit and refeed the sheets for forming an image on a second side. The refeeding unit has an intermediate tray, a pick-up roller for refeeding the sheets one by one and a containing section for feeding the sheets to the intermediate tray. Each of the sheets is fed into the intermediate tray by a first or a second roller of the containing section. The containing section is movable along a transporting way and set at such a position that the first and the second roller are positioned corresponding to the size of sheets to be contained in the intermediate tray.

An image forming apparatus includes a charging device for performing charging and discharging using a power storage device, and a plurality of loads each serving as a target of power supply from said charging device and being used in operation of the image forming apparatus. The image forming apparatus obtains information about an operation status of the image forming apparatus and sets priorities for being a target of power supply from the charging device for the plurality of loads, according to the obtained information. The image forming apparatus controls power supply operation of the charging device according to the information about the remaining capacity of the power storage device and the set priorities.

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.

Electronic device comprising: processing unit including accepting part accepting processing request from external device and executing process specified by request; secondary battery connected with external power source; and power-source device transitioning to operating state when request is accepted in waiting state, and transitioning to waiting state when processing unit completes executing process, wherein, in waiting state, power supply from external power source to processing unit is stopped and secondary battery supplies power to accepting part, and in operating state, power is supplied from external power source to processing unit. Power-source device includes controller executing first charge control operation to cause external power source to charge secondary battery when, in operating state, voltage of secondary battery is not higher than threshold, and end executing first charge control operation when transitioning to waiting state, controller updating threshold in response to increase in number of times first charge control operation is executed.
