Patent ID: 8605304

Claim:
An image processing apparatus comprising: a power supply switch configured to be operated to send an instruction to supply a power or shut down the power supply; a power control part configured to shut down the power supply after a predetermined power shutdown condition is established when the instruction to shut down the power supply is sent from said power supply switch; a prescript safe state transition part configured to perform a prescript safe state transition process to shift a predetermined number of previously set prescript parts among parts of said image processing apparatus to a predetermined safe state in which the power supply is shut down in safe in accordance with a predetermined transition procedure; a priority safe state transition part configured to perform a priority safe state transition process to shift a predetermined number of previously set priority parts among the parts of said image processing apparatus to said safe state in accordance with a predetermined transition procedure; and a transition process control part configured to cause said prescript safe state transition process to be executed before execution of said priority safe transition process, and cause the priority safe state transition process to be executed when a predetermined transition change condition is established in the prescript safe state transition process, wherein said power control part determines that said predetermined power shutdown condition is established when said prescript safe state transition process is completed, and shuts down the power supply after the completion of said prescript safe state transition process.
