Abstract: PURPOSE:To correct a print start position by a corresponding scanning light in response to the time difference of a synchronizing signal by allowing a beam light detection section to compare a detection output from a beam light detector at a comparison section having a different threshold level thereby generating plural synchronizing signals. CONSTITUTION:1st and 2nd laser beams outputted from a rotary mirror scanning unit are led to a sole beam light detector 308. Thus, it is not required to light the other laser light beam not used for print is not required to light and the service life of a laser oscillator is kept longer. The output of the detector 308 used comparison sections 400, 401 and is compares with a different reference voltage and each comparison section outputs horizontal synchronizing signals HSY0, HSY1. Thus, when the detection signal to the 1st and 2nd laser beam light are separated completely, after one beam light completes the scanning of the detector 308, the other beam light scanns the detector 308. In this case, the print start position is decided by the time difference of the two signals of the comparison section 400.
