Abstract:
A scanning exposure device including: a first and a second light sources emitting a first and second beam, respectively; a polygon mirror having reflecting surfaces; a first and a second optical sensors detecting the first and the second beam, respectively; and a controller storing first writing time until which an exposure by the first beam starts after the first beam is detected and second writing time until which an exposure by the second beam starts after the first beam is detected, for respective reference surface identifiers specifying the respective reflecting surfaces, and the controller acquires a first timing at which the first beam is detected and a second timing at which the second beam is detected for the respective reflecting surfaces identified by respective acquisition surface identifiers; and specifies a correspondence relation between the respective reference surface identifiers and the respective acquisition surface identifiers.

Claim (Index 6):
The scanning exposure device according to  claim 5 ,\n wherein when specifying the correspondence relation, the controller is configured to calculate:\n a first correlation coefficient, which is the correlation coefficient in a case where the reference time difference stored for each of the reference surface identifiers and the time difference between the first timing and the second timing acquired for each of the acquisition surface identifiers are associated with each other in one correspondence pattern; and \n a second correlation coefficient to a N th  correlation coefficient, each of which is the correlation coefficient in a case where the correspondence relation between the respective reference surface identifiers and the respective acquisition surface identifiers is associated in a correspondence pattern in which each of the reference surface identifiers or each of the acquisition surface identifiers is deviated from the one correspondence pattern by 1 to N\u22121, and \n the controller is configured to specify the correspondence relation between the respective reference surface identifiers and the respective acquisition surface identifiers by selecting a correspondence pattern in which a correlation coefficient is closest to 1 of the first correlation coefficient to the N th  correlation coefficient.
