摘要： The drive control device of a light scanning apparatus can be easily controlled, occurrence of overshoot can be prevented, and a scanning range of a mirror section can be adjusted in a short time. An amplitude adjusting section generates at least one of first adjusting voltage for acceleration, whose amplitude is higher than that of adjusting voltage for obtaining object amplitude, and second adjusting voltage for deceleration, whose amplitude is lower than that of the adjusting voltage for obtaining the object amplitude, and applies the same to a drive circuit for a prescribed time, to perform feedback control, when a comparing section generates an error signal, so as to cancel increase-decrease variation of the error signal.

摘要： The mirror swing range control device is capable of reducing a production cost of the control device and precisely adjusting a swing range of a mirror section. The mirror swing range control device comprises: a swing range detecting section for detecting a swing range of the mirror section swung by driving the vibration source; a signal processing section for arithmetically processing a detection signal, which is generated by the swing range detecting section, so as to generate an inverted detection signal; a standard value generating section for generating a standard value signal indicating a standard time interval; a comparing section for adding the inverted detection signal to the standard value signal, integrating calculated errors and generating an error signal; and a swing range adjusting section for performing feedback control, in which a cancelling signal is applied to the drive circuit for a prescribed time when the comparing section generates the error signal, so as to cancel an increase-decrease value of the error signal.
