A position sensor includes a receiver capable of receiving a position signal from an external source, and an inertial motion unit capable of sensing movement and producing a movement signal based upon the sensed movement. In the process, a target object is exposed to plasma of a fluorocarbon gas and a thickness of a protective film on the second region is larger than a thickness of a protective film formed on the first region. The attenuating section 31 receives a rotational angular velocity \u03c9e of the motor 12. A second set of rays is defined between the appliance and the tooth, and the distance along each ray is determined. The telephoto discernment PAR code includes at least three dots, for designating production of a pseudo telephoto print from a region in an imaging frame in the photo film corresponding to the telephoto view field.
