Patent ID: 7696653

Claim:
A movable-body apparatus, comprising: a movable body; heat-dissipating unit mounted to the movable body to remove heat from the movable body; a driving device for driving the movable body in a predetermined plane defined by a first axis and a second axis intersecting the first axis; and a waste-heat member disposed, without contacting the movable body, relative to the heat-dissipating unit and configured to absorb heat received by the heat-dissipating unit from the movable body; wherein one of the waste-heat member and the heat-dissipating unit extends over a predetermined respective range relative to a respective one of the axes, and the other of the waste-heat member and heat-dissipating unit extends over a respective predetermined range relative to the respective other of the axes within the predetermined plane so that, as the movable body is moved within the plane, at least a portion of the heat-dissipating unit remains in heat-transfer confrontation with at least a portion of the waste-heat member.
