OSCILLATING BODY APPARATUS, LIGHT DEFLECTOR AND IMAGE FORMING APPARATUS USING THE SAME |
摘要 |
PROBLEM TO BE SOLVED: To solve a problem that a sufficient control effect and a stable driving are not obtained when a same control parameter is given to a feed back control regardless resonance frequencies because the response characteristic to a driving signal of an oscillating body apparatus is different depending upon devices. SOLUTION: The oscillating body apparatus has: a supporting part; an oscillation system having a plurality of oscillating bodies and a plurality of torsion springs; driving means which drive the oscillation system; a driving control means which controls the driving means; an oscillation detection means which detects the oscillation state of the rocking bodies; a resonance frequency calculation means which calculates the resonance frequency of the oscillation system on the basis of the output of the oscillation detection means; and a control parameter adjusting means which adjusts the control parameter of the driving control means. The control parameter adjusting means adjusts the control parameter on the basis of the output of the resonance frequency calculation means. COPYRIGHT: (C)2009,JPO&INPIT |
