摘要:
An image processing apparatus has an input device such as a scanner for inputting an original image, and a mode setting device for setting an editorial processing mode such as trimming, enlargement or size reduction to be executed on the input image. The apparatus further has a processing device for performing, in accordance with the editorial processing mode set by the mode setting device, the editorial processing on the image input by the input device. The apparatus further has a storage control device for storing, in a storage medium such as a disk, the image after the editorial processing performed by the processing device, together with reproduction data which corresponds to the executed editorial processing mode. The reproduction data is used for reproducing the original input image from the image after the editorial processing.

A control board includes a main-board and a plurality of sub-boards which control loads. The sub-boards each include a providing unit which provides a board type ID, a read unit which reads an installation location ID, and a transmission unit which transmits the board type ID and the installation location ID to the main-board. The main-board includes a communication control unit, a configuration information acquisition unit which acquires configuration information expressed by a combination of the board type ID and the installation location ID, an analysis unit which analyzes the configuration information, and a control unit which controls the sub-unit on the basis of information analyzed by the analysis unit.
摘要:
An image forming apparatus such as a copier with a detachable process cartridge is provided with a first memory for storing the number of copying operations; a count renewing unit for increasing the count of the first memory and a second memory in the process cartridge, at each copying operation, a comparator for comparing the counts in the first and second memories, and a controller for determining a process condition specific to the process cartridge in case the counts do not mutually coincide. The service life of the process cartridge can be more precisely judged, and the process condition can be more appropriately determined for each process cartridge.
