ABSTRACT:
The present invention is to provide a program update apparatus which carry out an updating process automatically in a device built-in system (in particular, in a system for an apparatus that needs to be always operated), and makes the system free from freezing. A downloaded new operation program is stored in a storage area that is separated from a storage area in which a previous operation program that has been operated is stored. Then, the new operation program24is activated so that an execution application is operated on the new operation program24. In the event of a failure in activating the new operation program, the previous operation program is reactivated so that the system is operated on the previous operation program21.Moreover, in a state where the new operation program or the previous operation program is successfully activated, if the execution application is not activated, the setting required for the execution application is recovered by a recovering application.
