Image processing apparatus, computer readable storage medium storing power supply control program

An image processing apparatus comprising:

• an image scanner that executes image processing to scan in an image of an original when there has been an image scanning instruction, the image scanner comprising an original platen on which the original is placed, an opening and closing member capable of moving between two positions that are an open position for placing an original on the original platen, and a closed position in which the original is disposed between the original platen and the opening and closing member, a closing operation detection unit that detects closing operation of the opening and closing member from the open position to the closed position, and a determination unit that determines a size and orientation of the original placed on the original platen when closing operation has been detected by the closing operation detection unit;
• an image forming unit that forms an image on recording paper based on either image data scanned by the image scanner or image data received from outside of the image scanner;
• a switching unit that independently switches between power supply or supply interruption for a plurality of respective image processors at least including the image scanner and the image forming unit;
• a notification unit that, when there has been a power save release instruction with the image scanner in a power interrupted state, after power supply has been resumed the notification unit executes notification to urge selection of either manual input of the size and the orientation of the original or opening and closing operation of the opening and closing member;
• and
• an image scanning processing control unit that executes image scanning processing of the image scanner at time when the size and the orientation of the original have been confirmed based on operation according to notification of the notification unit.
