摘要：A scanning optical device focuses a laser beam emitted by a laser oscillator by afirst lens, scans it by a deflector to direct it onto a medium to be scanned, by a secondlens, deflects a portion of the light transmitted through the second lens by a stationarymirror, directs it to a photo-sensor by a third lens and uses an output of the photo-sensor to trigger a horizontal synchronous signal. At least two of the first lens, thesecond lens and the third lens are integrally formed.
