A device on which transmitting devices are loaded the transmitting device is installed detachably on a sensor device, which is implanted in an examinee to acquire a biosignal from said examinee, and said transmitting device acquires bio-information from the biosignal acquired by the sensor device and transmits same to an external device. The device comprises: a first and a second port on which the transmitting devices are mounted and loaded and respective communication units, which are provided on said ports and communicate with the transmitting devices mounted on the respective ports. When a transmitting device is newly mounted on one of the ports, the device acquires the data to be transmitted including communication identifying information for said transmission from the newly mounted transmitting device using the communication unit of said port, and transmits said acquired transmission data to the other transmitting device that is already mounted on the other port using the communication unit provided on said other port.Linvention concerne un dispositif sur lequel des dispositifs de transmission sont chargés le dispositif de transmission est installé de façon détachable sur un dispositif de capteur, qui est implanté dans une personne examinée pour acquérir un biosignal provenant de ladite personne examinée, et ledit dispositif de transmission acquiert des bioinformations provenant du biosignal acquis par le dispositif de capteur et les transmet à un dispositif externe. Le dispositif comprend : un premier et un second port sur lesquels les dispositifs de transmission sont montés et chargés et des unités de communication respectives, qui sont disposées sur lesdits ports et communiquent avec les dispositifs de transmission montés sur les ports respectifs. Lorsquun dispositif de transmission est nouvellement monté sur lun des ports, le dispositif acquiert les données à transmettre comprenant des informations didentification de communication pour ladite transmission
