Abstract:
Provided is an electronic machine that is able to update only necessary firmware. The electronic machine includes a panel unit, a storage device, a firmware-management unit, and a system-control unit. The storage device stores a plurality of firmware that is divided for each function, and that has version information to which package information is given that indicates a combination of latest versions of firmware that guarantees operation. The firmware-management unit has a latest version of a management table in which version information of the plurality of the latest versions of firmware, and package information that indicates a combination of the firmware are registered, and that is downloaded from an information-distribution server, and that based on an instruction to check versions of the firmware, checks whether or not version information of the respective firmware that is read from the storage device and version information that is registered in the management table match. The system-control unit instructs the firmware-management unit to check the versions and causes the check results of the firmware-management unit to be displayed on the panel unit. Moreover, when there is an instruction via the panel unit to download the latest version of the management table, the system-control unit sends a request to the information-distribution server for downloading the latest version of the management table, and when there is an instruction via the panel unit to perform a download based on the check results of the firmware-management unit, sends a request to the information-distribution server for a download.
