Patent ID: 8496576

Claim:
An in-vivo information acquiring system comprising: a magnetic field generating apparatus comprising an input section for inputting first identification information that allows an in-vivo information acquiring apparatus to be controlled to be distinguished from other in-vivo information acquiring apparatuses, and a magnetic field generating section that generates a magnetic field signal that controls the in-vivo information acquiring apparatus to be controlled; and an in-vivo information acquiring apparatus introduced into an object to be examined and to be controlled, comprising an in-vivo information acquiring section that acquires information inside the object to be examined, a power supply source that supplies power to be used to drive the in-vivo information acquiring section, a magnetic field signal receiving section disposed outside that receives the magnetic field signal from the magnetic field generating apparatus, a storage section that stores second identification information that allows the in-vivo information acquiring apparatus to be controlled to be distinguished from the other in-vivo information acquiring apparatuses, and a power supply control section that controls a power supply from the power supply source to the in-vivo information acquiring section, wherein when the in-vivo information acquiring system has any one of configurations where (1) the magnetic field generating apparatus comprises a first comparing section that compares the first identification information with the second identification information and judges whether both pieces of information are the same or different, and (2) the magnetic field generating apparatus comprises the first comparing section and the in-vivo information acquiring apparatus to be controlled comprises the second comparing section which compares the first identification information with the second identification information and judges whether both pieces of information are the same or different, and when the judgment of the first comparing section is a judgment that both pieces of information are the same, the power supply control section supplies or shuts off power from the power supply source to the in-vivo information acquiring section.
