An IMES transmitter has a control unit, a non-volatile memory to record a transmitter number of the IMES transmitter, and a data I/F. When registration data Dset associating the transmitter number with position information is input from the data I/F, the control unit records the position information included in the registration data Dset if the registration data Dset includes the transmitter number of the IMES transmitter, and transmits the registration data Dset from a transmitting unit if the registration data Dset includes the transmitter number of another position information transmission device. The device registers various information such as position information on plural position information transmission devices without requiring complicated equipments.
