Abstract: An inkjet printer includes: a casing; a first control board; a carriage; a head; a transmission antenna; and a reception antenna. The first control board is configured to reciprocate in a scanning direction crossing a conveying direction of a recording medium. The head is mounted in the carriage and has a plurality of nozzles. The transmission antenna is connected to the first control board. The transmission antenna is configured to transmit, through near field communication, an ejection signal for controlling ejection of ink from the plurality of nozzles. The reception antenna is provided in the carriage. The reception antenna is configured to receive the ejection signal from the transmission antenna. The near field communication has a communication range smaller than a size of the casing.

Abstract: A communication apparatus including: a relaying section which relays phone conversation between a sub-communication apparatus and an external communication apparatus which is in a communicable connection state by the communication controlling portion; a request section which requests, when a transmission command for transmitting transmission data has been transmitted from the sub-communication apparatus performing the phone conversation with the external communication apparatus, a data processing apparatus to transmit the transmission data while maintaining a connection state between the communication apparatus and the external communication apparatus to the communicable connection state; a receiving section which receives the transmission data transmitted from the data processing apparatus in response to the request of the request section; and a transmitting section which transmits the transmission data received by the receiving section to the external communication apparatus being in the communicable connec
