Abstract
A body-insertable apparatus that is used in a state of being introduced in a body of a subject, and that performs a predetermined function inside the body of the subject includes an imaging circuit, a batterythat supplies with energy to be used to drive the imaging circuit, a power switchthat switches energy supply to the imaging circuitfrom the battery, a switch control circuitthat performs a switching control of the power switch, and a signal detecting circuitthat detects a magnet and that transmits, to the switch control circuit, a control signal to cause the power switchto toggle the switching control based on this detection state, and is possible to be turned on and off a main switch at a desirable timing before introduction into the body of the subject, thereby achieving energy saving in which a life of a battery is saved, and suppressing unnecessary radio wave radiation.
