Claim:
1. A scanning endoscope system comprising: a fiber configured to guide illuminating light emitted from a light source; a first actuator disposed on a side of the fiber, wherein the first actuator is configured to deform by expanding and contracting upon application of an applied voltage, according to a first drive signal, thereby swinging the fiber; a second actuator disposed at a position facing the first actuator across the fiber, wherein the second actuator is configured to deform by expanding and contracting upon application of according to an applied voltage, according to a second drive signal, thereby swinging the fiber; a drive signal output section configured to output the first drive signal and the second drive signal, wherein the first actuator and the second actuator are configured to deform in opposite directions when a polarity of the first drive signal and a polarity of the second drive signal are the same; and a controller configured to control the drive signal output section to:
