A communicating unit performs a communication operation to a destination address designated by an address designating unit. A result displaying unit displays a result of an operation stored in a result storing unit in a readable manner. Upon the address designating unit designating the destination address, a control unit, with a plurality of inputs of the destination address, causes the communicating unit to perform the communication when the destination address is identical at each of the inputs, and causes the result storing unit to store therein a result of an address mismatch when the destination address is not identical at each of the inputs. |
