A control circuit receives in advance data representing a predetermined number of copy jobs to be provided from a scanner and data representing a predetermined number of print jobs to be provided from external equipment, queues each of the copy jobs and print jobs on the basis of such data, and causes the jobs to be processed in a time divisional and parallel manner. Basically, the control circuit gives higher priority to the copy job. The priority order can be changed according to an instruction from a user interface. When a current job has been suspended, the control circuit causes a succeeding job to be processed earlier.

Multi-function image processing system

Image data obtained by a image reading unit is stored in a single file of a hard disk on a page basis. An image data control table is held in a main control circuit, and contains job number data and page number data both for inputting and a page number list for ourputting which represents the output order of pages. The image data is read from the hard disk and reproduced by an image output unit according to the order set in the page number list.

Image processor

An image processing system including an image read section for reading an image on a document, data compressing means for compressing image data as read by the image read section, data decompressing means for decompressing the image data compressed by the data compressing means, an image output section for outputting the image data as decompressed by the data decompressing means in the form of a hard copy, data storage means for storing the image data as compressed by the data compressing means, a page buffer for storing the data of a plurality of pages every page, the data being transferred to and from the data storage means, and control means for controlling the compressing and decompressing of the data by the data compressing means and the data decompressing means, and the data transfer between the data storage means and the page buffer that is done every page. When the image data is transferred from the data storage means to the image output section, the control means reads the image data of two pages from the data storage means and successively stores the image data of two pages into the page buffer, and stores image data of the next page into the page buffer if the image data of one page is read out of the page buffer.
