Abstract:
1. A magnetic control method for an endoscope device comprising a capsule sensor and a driving device, comprising the following steps: providing a turn table and a plurality of outer magnetic elements disposed in the driving device wherein the turn table rotates around a first axis, and the outer magnetic elements are axially disposed with respect to the first axis so that the magnetic poles of the outer magnetic elements whose polarities are different are facing the turn table alternatively; providing an inner magnetic element disposed in the capsule sensor and radially disposed with respect to a second axis; attracting the inner magnetic element by the magnetic field generated by at least one of the outer magnetic elements; moving the capsule sensor by the movement of the driving device; rotating the outer magnetic elements around the first axis at a first speed to spin the capsule sensor around the second axis which is perpendicular to the first axis; and rotating the outer magnetic elements around the first axis at a second speed slower than the first speed to rotate the capsule sensor around a third axis which is parallel with the first axis.
