Abstract / Hauptanspruch
A position detecting device (200) includes a first position detector (111), a second position detector (112), and a controller (113). The first position detector (111) controls a reading device (201) to detect, as a first detection result, an outer shape of a processing subject and a position of an image pattern on the processing subject. The second position detector (112) controls the reading device (201) to detect, as a second detection result, a mark (M) arranged on a position reference member (202), the mark (M) corresponding to a predetermined position in the reading device (201). The controller (113) detects a first correction value of the reading device (201) and a second correction value of the reading device (201) corrected by the first correction value on basis of the second detection result and reflects the values to the first detection result to correct a processing position in the processing subject.
