The rolling bearing has a first bearing ring, a second bearing ring and a plurality of rolling bodies which are arranged between the first bearing ring and the second bearing ring. If a motor is locked before an original point position signal is outputted, a reciprocating operation for moving the wiper arm temporarily in the forward path direction and then moving the wiper arm again in the backward path direction is performed. Therefore, a more accurate high precision alignment can be performed, and there is no requirement to increase the NA of the detection optical system, nor to prepare a special short wavelength light source, meaning increases in the size and cost of the apparatus can also be prevented. An RFID scanner is used to interrogate the transponders, and the retrieved information is stored and acted on as appropriate.
