| 英文摘要 | Disclosed is a laser scanning unit for emitting a laser beam which scans on a surface to be scanned within a predetermined scanning range. The laser scanning unit has a laser diode, and a laser diode controller for controlling the laser diode to emit the laser beam. The laser beam has an intensity corresponding to one of a predetermined graduation steps within a intensity range defined by a first intensity and a second intensity greater than the first intensity in accordance with an image data. The laser scanning unit is further provided with a controller which is capable of shifting the intensity range by changing the first and second intensities. |
