CONTROL SIGNAL TRANSMITTING APPARATUS

摘要

A magnetic field generating apparatus (20) transmits control signals to a capsule endoscope (10) that is controlled to start/stop in accordance with the control signals generated by a magnetic field. The magnetic field generating apparatus (20) is provided with: a case (25) which has a housing section (21) wherein the capsule endoscope (10) is disposed; a magnetic field generating section (42) which generates the magnetic field; and a shield section (26) which shields a leaked magnetic field that is leaked to regions other than the housing section (21) from the magnetic field generated by the magnetic field generating section (42).
