1. A communication device comprising:
a connector which is inserted into a first device;
a communication circuit which performs wireless communication with a second device;
a processing circuit programmed to execute
communicating with the first device via the connector,
generating a first signal representing that the connector is pulled out from the first device when the processing circuit detects that the connector is pulled out from the first device, and
transmitting the first signal to the second device by controlling the communication circuit; and
a first storage circuit which stores communication data based on data obtained from the first device via the connector, wherein
the processing circuit is programmed to erase the communication data stored in the first storage circuit when the processing circuit detects that the connector is pulled out.
