Abstract

A digital copier system wherein a plurality of applications share resources. When two or more applications generate requests for using resources including an image forming device, they are allowed to use the resources in an interleaved order matching a predetermined priority order. Accordingly, different applications alternatively access the resources simultaneously in an order determined by the priority order. For example, a copier can take priority over a printer or facsimile machine to use an image reading device while the printer or facsimile machine uses the image forming device. A user gives a desired priority order to the applications beforehand, and the system is conveniently used even when a plurality of applications share the image forming device.
