The unit table can be moved between a treatment position drawn near to the vicinity of the patient and a retreat position kept away from the patient and is arranged in the same direction as the center axial line in the longitudinal direction of a patient's chair at the treatment position. The unit table and the astral lamp are mutually set to a relative positional relation wherein the astral lamp is present at a predetermined irradiation position illuminating the mouth of the patient when the unit table is set at the treatment position. Further, both of them are mutually connected so as to be moved between the predetermined irradiation position and the retreat position of the astral lamp without changing the relative positional relation when the unit table is moved between the retreat position and the treatment position. <P>COPYRIGHT: (C)2004,JPO |
