Image forming apparatus and method of controlling the same

摘要

An image forming apparatus includes a printer unit to form an image and outputting the image on a sheet, a storage unit, a control unit to control hardware resources of the image forming apparatus including at least the printer unit and the storage unit by executing a first OS that is activated on the image forming apparatus and a control program operating on the first OS and that can execute second to N-th OSs that activate at least one application and an emulator disposed between the first OS and the second to N-th OSs to allow the second to N-th OSs to operate on the first OS, wherein the control unit can cause the first OS to enter into a sleep mode and inhibits the first OS from entering into the sleep mode when at least one of the second to N-th OSs is active.

1. An image forming apparatus comprising:
a printer unit to form an image based on image data and output the image on a sheet; a storage unit storing a first operating system and second to N-th (N is an integer of 2 or more) operating systems; and a control unit that controls hardware resources of the image forming apparatus including at least the printer unit and the storage unit by executing the first operating system that is activated on the image forming apparatus and a control program operating on the first operating system and that can execute the second to N-th operating systems that activate at least one or more applications and an emulator that is disposed between the first operating system and the second to N-th operating systems to allow the second to N-th operating systems to operate on the first operating system, wherein the control unit can cause the first operating system to enter into a sleep mode and inhibits the first operating system from entering into the sleep mode when at least one of the second to N-th operating systems is active, and the emulator emulates hardware on which the second to N-th operating systems operate.
