Abstract
A beam light scanning apparatus capable of speeding up transfer of image data used for scan with a beam light while suppressing an increase of the parts cost. The beam light scanning apparatus includes a laser oscillator for emitting a beam light for scan, and a unit for processing and supplying image data of a target image in each line in a direction of main scan in response to a sync signal. The apparatus further includes a unit for acquiring the supplied image data after a certain time from generation of the sync signal, and a unit for controlling operation of the laser oscillator by a driving signal which is generated based on the acquired image data.
