Capsule medical apparatus
First Claim
1. A capsule medical apparatus comprising:
- a capsule exterior member;
an electric circuit arranged in the exterior member;
a battery arranged in the exterior member; and
a switch circuit for controlling to switch a state of energy supply from the battery to the electric circuit to one of an ON-state and OFF-state;
wherein the switch circuit includes;
a first physical quantity detecting unit which can detect a temporary change of a first physical quantity outside the exterior member and which, upon detecting the temporary change of the first physical quantity, starts the energy supply from the battery;
a second physical quantity change detecting unit which can detect a temporary change of a second physical quantity outside the exterior member and which, upon detecting the temporary change of the second physical quantity, stops the energy supply from the battery; and
a power supply state holding unit which holds the state of energy supply from the battery to the electric circuit to the OFF-state until the first physical quantity change detecting unit detects the temporary change of the first physical quantity, and holds the state of energy supply from the battery to the electric circuit to the ON-state until the second physical quantity change detecting unit detects the temporary change of the second physical quantity; and
wherein the first physical quantity and the second physical quantity are physical quantities of different types from each other.

Abstract
A capsule medical apparatus includes a capsule exterior member and a sensor that can detect the change of an atmospheric physical quantity caused outside the exterior member in the non-contact state, and performs, based on the temporary change in atmospheric physical quantity detected by the sensor, at least one of first control for switching operation from the ON-state of energy supply to the electric circuit from the battery to the OFF-state of the energy supply and of second control for switching operation from the OFF-state of the power supply to the ON-state of the power supply, and holds the state of energy supply switched by the control until another change of atmospheric physical quantity is detected.
