Abstract

PURPOSE:To dispense with a coiling mechanism of a cable, and to improve the performance and a service life of the cable by constituting a signal receiving cable in an MRI device so that an examinee can be contained into a bed by dead weight of the cable in connection with a movement of a horizontal moving part of a placing device. CONSTITUTION:A top plate 4 on which an examinee can be placed in a lying state is placed so that it can be taken in and out freely and can be moved horizontally and freely against a static magnetic field space, and a signal receiving cable 5 for connecting a receiving coil for receiving a nuclear magnetic resonance signal and a signal amplifier in connection with a movement of this top plate 4 is contained in a bed. That is, the cable 5 is connected to the signal amplifier through a connector base 8 in a state that one end and the other end are fixed to the rear end of the top plate 4, and the rear part of a pan 6, respectively. Also, a movable part 5a placed in an unloose state at the time when the top plate 4 is in an initial position on the bed is loosened in connection with a movement of the top plate 4, contained by dead weight on the pan 6 combined with a water receiver, and the part protruding from the pan 6 is extended on a cable receiver 7.
