Image Forming Apparatus and Method of Controllling the Same
First Claim
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; 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 a 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 second to N-th (N is an integer of 2 or more) 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, whereinthe 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.

Abstract
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.

18. A method of controlling an image forming apparatus comprising:
-
a printer unit that forms an image based on image data and outputs the image on a sheet; and
a storage unit,the method controlling hardware resources of the image forming apparatus including at least the printer unit and the storage unit by executing a first operating system that is activated on the image forming apparatus and a control program operating on the first operating system, the method comprising the steps of; executing second to N-th (N is an integer of 2 or more) operating system 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; and causing the first operating system to enter into a sleep mode, wherein the first operating system is inhibited from entering into the sleep mode when at least one of the second to N-th operating systems is active. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
