Abstract
An analyzing deviceincludes position detection marks, each having one of a reflective surface, a refractive surface, and a light shielding surface that block output light incident on a sensorfrom a light sourcewhen the output light reaches a rotation detection position just before or behind measurement spots, andof the analyzing device. Output signals from the sensorfor reading the measurement spots, andare stored in a memory, the positions of the measurement spots, andare determined based on light receiving data stored in the memory, and only a desired analyzing signal is extracted. Thus even when the number of measurement spots increases, it is possible to read the measurement spots without adding any components.
