<P>PROBLEM TO BE SOLVED: To solve a problem of being unable to deliver reception data which a management PC has not obtained to a user due to the data disappearance when blackout and the like occurs because of property of a volatile memory, although the volatile memory is used in the storage area of an external storage. <P>SOLUTION: When a first communication unit communicates with an external device, a first storage unit stores reception data received from the external device regardless of on or off of electric power. In addition, a second storage unit stores conversion data converted to a prescribed format from the data received from the external device only when electric power is on, and an output unit is capable of outputting the conversion data. Here, an electric power determination unit is capable of determining whether electric power is on or off, and based on determination that power has been turned on, a restoration management unit converts the reception data in the first storage unit into conversion data to make the second storage unit store the conversion data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
