A first communication unit performs a non-contact communication with an external device and receives setting data from the external device. A second communication unit performs a wireless communication with the external device. A control unit establishes the wireless communication between the second communication unit and the external device by using the setting data. A data processing unit stores the setting data in a storage unit before the wireless communication is released. A communication releasing unit releases the wireless communication. The control unit uses the setting data stored in the storage unit at a time of re-performing a wireless communication between the second communication unit and the external device. The communication releasing unit releases the wireless communication when the power is not being supplied via a power input unit to which power is input from outside.
