Abstract
In a capsule 3 as a medical apparatus inserted into a body cavity, the lengthwise direction of the capsule 3 is used as an insert axis, a manipulation/input device 8, which is magnetized in a direction orthogonal to the insert axis, is disposed at the center position of the insert axis. A magnetic field generation device 4, which is disposed outside of a body, is caused to generate a vibration magnetic field in a direction parallel with the insert axis of the capsule 3 by turning on a vibration (ON/OFF) switch 8f of a manipulation/input device 8 so that couples having lines of action, which are in parallel with the insert axis, are exerted on the capsule 3, thereby the capsule 3 executes a swiveling motion about the insert axis and smoothly travels along a cavity organ.
