When completing the first processing by the execution means 1a and when receiving again the request 4 adding the same information 3 as the first processing, a transmitting means 1b for notification of completion transmits a notification 5 of completion of the first processing. A transmitting means 2a for processing request transmits the request 4 adding the information 3 to a server device 1. When receiving the notification 5 from the device 1, a second processing execution means 2b executes a second processing.
