Abstract: The apparatus for reading a luminescence pattern is equipped with a stage on which the sample to be read is mounted. A photoreceptor disk is installed in the lower part of the stage and scans and condenses light from the luminescent pattern of the sample at positions determined by the rotation of a rotary plate. A transport mechanism causes the stage and the photoreceptor disk to undergo relative motion. An optical guide part guides the light from the luminescent pattern to a photoelectric converter. The optical guide part may include mirrors or one or more optical fibers. The photoelectric converter converts the light into an electrical signal. A controller controls how scanning is performed by the photoreceptor disk and transport mechanism and generates a read scanning position signal. A data processor performs data processing by converting the electrical signal into a digital signal and obtains a scanning position signal from the controller.
