摘要：A scanning optical device focuses a laser beam emitted by a laser oscillator (2)by a first lens (21a), scans it by a deflector (4) to direct it onto a medium to be scanned(7), by a second lens (21b), deflects a portion of the light transmitted through the secondlens by a stationary mirror (8), directs it to a photo-sensor (11) by a third lens (21c) anduses an output of the photo-sensor to trigger a horizontal synchronous signal. At leasttwo of the first lens (21a), the second lens (21b) and the third lens (21c) are integrallyformed.
