A storage part preliminarily stores a program for executing processing and validity period information indicating a period during which the program can be executed. A first control part determines necessity/non-necessity of updating the validity period information stored in the storage part, based on the validity period information stored in the storage part and the date information acquired by the date information acquisition part, and controls a communication part to transmit request information for requesting a new program including at least new validity period information to the server device, based on the determination result. A second control part receives the new program including the new validity period information from the server device and controls the storage part to store the received new program. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
