Using a guidance system with a simple configuration, propulsive motion along a longitudinal direction and changing of the propulsion direction are easily performed with good precision and stability. There is provided a capsule-type medical apparatus which is inserted into the body of a subject and is guided by an external magnetic field, the capsule-type medical apparatus comprising: a substantially cylindrical capsule; a propulsion mechanism for converting rotary motion about a longitudinal axis R of the capsule into propulsive motion along the longitudinal axis R; a magnet accommodated inside the capsule and disposed in such a manner that the magnetic-pole direction thereof can be switched between a direction along the longitudinal axis R and a direction intersecting the longitudinal axis R; and a securing portion for securing the magnet to the capsule in each of the switched states of the magnetic-pole direction.

At an on-cell reset, a positive ramp wave of an ultimate voltage, which is larger than a maximum voltage of a sustain pulse, and smaller than an ultimate voltage of a positive ramp wave applied to a Y electrode at an all-cell reset, is applied to the Y electrode to make a weak discharge occur at a cell where it is non-lighting at a previous sub-field and a wall charge thereof is decreased due to an influence from an adjacent cell, thereby, it makes it possible to return a wall charge state to a normal state, to be capable of lighting a cell to be lighted securely based on a display data.
