The technique of the invention relieves the requirement of repeated positioning to a wireless communicable range in the process of data transmission to and from each of multiple cartridges by wireless communication. A carriagewith multiple ink cartridgesthroughmounted thereon is stopped at a position Pwhich is away a distance Dfrom an antennaand is conveyed from the position Pat a preset velocity V. With the movement of the carriagedetection storage modulesthroughmounted on the ink cartridgesthroughsequentially approach to the antennaand establish communication with a control circuitof a printer via the antennaof a receiver transmitter unitThis arrangement enables data transmission between the control circuitand each of the detection storage modulesthroughwithout repeatedly stopping the carriage

Recording apparatus and communication method

A first plate member constitutes a part of a main frame of a liquid ejection apparatus. A second plate member is extended from the first plate member such that a first part thereof opposes to a traveling path of a carriage which carries a plurality of liquid containers each provided with an IC chip and a receiving antenna. A transmission antenna is provided on an antenna board. The antenna board is mounted on the first part of the second plate member. The second plate member is formed with a first region which allows the transmission antenna to establish radio communication with the receiving antenna, and a second region which shields radio waves.
