する多点同期装置。 A multipoint synchronization system that includes a grating that is scanned by a scanning beam, a photodetector that detects the beam that passes through the grating, and a phase synchronization system that generates a synchronized clock in synchronization with the output signal of the photodetector. A multi-point synchronization device, characterized in that the grating is configured such that the output signal of the light detection means is generated from before the image area start position.
