Abstract:
A position detector includes a reading device, a position reference member having a mark opposite the reading device, and circuitry. The circuitry controls the reading device to detect the contour of the processing target and the position of the image pattern on the processing target and the position of the mark and corrects a processing position for the processing target to offset distortion of the reading device.
