In-vivo information acquiring system
First Claim
1. An in-vivo information acquiring system comprising:
- an in-vivo information acquiring apparatus introduced into an object to be examined, 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;
an external signal detection section that detects an external signal and outputs an internal signal according to the detected external signal;
a power switch that controls a power supply from the power supply source to the in-vivo information acquiring section; and
a power supply control section that causes the power switch to operate according to the internal signal inputted from the external signal detection section, andan external signal generating apparatus disposed outside the in-vivo information acquiring apparatus, comprising;
an external signal generating section that generates the external signal;
an operation section that outputs an operation signal instructing the external signal generating section to generate the external signal according to an operation; and
a masking section that masks the operation signal from the operation section to the external signal generating section for a predetermined period.

8. A capsule endoscope system comprising:
-
a capsule endoscope to be introduced into an object to be examined, comprising; an in-vivo observation section that acquires an image inside the object to be examined; a battery that supplies power used to drive the in-vivo observation section; a magnetic field detection section that detects a magnetic field signal and outputs an internal signal according to the detected magnetic field signal; a power supply switch that controls a power supply from the battery to the in-vivo observation section; and a power supply control section that causes the power supply switch to perform a toggle operation according to the internal signal inputted from the magnetic field detection section, and a magnetic field generating apparatus disposed outside the capsule endoscope, comprising; a magnetic field generating section that generates the magnetic field signal; an operation switch that outputs an operation signal instructing the magnetic field generating section to generate the magnetic field signal according to an operation by a user; and a timer that extends a pulse width of the operation signal to the magnetic field generating section from the operation switch for a predetermined period.
