PROBLEM TO BE SOLVED: To prevent reception of second data from being erroneously recognized by receiving noise that is generated when an MCU is operated, by a second antenna, in a transmission device formed by proximately disposing a plurality of transmitters in the same configuration in a fixed three-dimensional array, each transmitter being formed by accommodating an electronic circuit including the MCU, a first antenna for transmitting first data generated by the transmitter to the outside by radio and a second antenna for receiving the second data for adjusting timing among each transmitter to transmit the first data from the first antenna by radio from the outside by radio within at least a predetermined housing.SOLUTION: In the vicinity of an arrangement position of the electronic circuit including the MCU in a housing 130 of each transmitter, a conductor plate 500 that is electrically insulated is provided, thereby blocking the noise that is generated when the MCU is operated.SELECTED DRAWING: Figure 10 |
