ABSTRACT:
An apparatus for processing a rotary member, comprising: a rotational drive for driving the rotary member so as to rotate the rotary member about an axis of the rotary member; an encoder for detecting a rotational position of the rotational drive device; a control device for controlling, in response to an output signal of the encoder, the rotational drive device so as to rotate the rotational drive device at a uniform speed; a processing device for processing an arbitrary position of the rotary member rotating at the uniform speed; a position detecting device for detecting, on the basis of the output signal of the encoder, a rotational position of the rotary member by raising a resolution of the output signal of the encoder; and a processing control device for controlling the processing device on the basis of the rotational position of the rotary member detected by the position detecting device.
