<p>PURPOSE:To improve the processing efficiency by writing key information of a device main body, which is effective for a program stored in an external storage medium, on the device main body side at the time of setting the external storage medium to the device main body and selecting a processable key input for extended soft based on this key information. CONSTITUTION:When an external storage medium 4 is set to a device main body 1, key information of the device main body 1 which is effective for the program stored in the external storage medium 4 is written on the side of the device main body 1. A processable key input an be selected for extended soft based on this key information to omit the unnecessary processing of the key input in the device main body 1. Thus, the key input processing for extended soft is efficiently performed.</p> |
