Title: Imaging apparatus
Inventor: ITABASHI AKIHISA
IPC: B41J2/44
Filed: 2000-07-27
Abstract: PROBLEM TO BE SOLVED: To correct variation in the scanning length caused by a deflector, e.g. a polygon scanner, and fluctuation of an image appearing at the end part thereof. SOLUTION: A 1/n counter 331 is reset by a mark detection signal from a deflector to resume counting of sync pulse signal and to count 1, 2, 3,..., n faces before being reset again by a mark detection signal from the deflector. Deflection scanning face of the deflector is determined by repeating the operation. Since the scanning width is expanded/contracted by the deflection reflective face, information for each face is stored in a count setting section 334 as line information. The line information is loaded to an N-adic counter 330 according to an identification signal indicative of a face being scanned next by a line counter 333 and a count is set. The N-adic counter 330 generates a Phase-Set signal and shifts the phase of a write clock.
