wherein the control unit is configured to execute a first preparation operation in a case where the initialization operation
is performed when the function is not restricted by the function restriction unit, and to execute, in a case where the initialization
operation is performed when the function is restricted by the function restriction unit, a second preparation operation in
which a preparation operation corresponding to the restricted function is excluded from the first preparation operation.
