DATA STORAGE TRANSMISSION APPARATUS, DATA LOGGER, DATA TRANSMISSION SYSTEM, AND RADIO WAVE OUTPUT ADJUSTMENT UNIT

摘要

PROBLEM TO BE SOLVED: To provide a technology for achieving the adjustment of a radio wave output without largely changing the configuration of a control unit about a data storage transmission apparatus for transmitting by radio stored data of the control unit for storing data to a data logger by an antenna. SOLUTION: The data storage transmission apparatus 10 is provided, which includes: a control unit 11 storing data; an antenna 12 for transmitting stored data of the control unit 11 by radio; a shielding mechanism 13 for moving a radio wave shielding cover 14 for covering the antenna 12 to open and close the cover; a shielding mechanism control part 16 for controlling the driving of the shielding mechanism 13; and a trigger signal receiver 17 for receiving a data output command transmitted by radio from the data logger 20, and adjusts a moving amount from a closed position of the cover 14 in accordance with the receiving strength of the data output command. A data logger 20, a data transmission system and a radio wave output adjustment unit are also provided. COPYRIGHT: (C)2011,JPO&INPIT
