Abstract
An optical system driving device comprising: a lamp unit which emits an optical beam for scanning an object and moves with respect to the object; a photosensitive member which receives a reflection light reflected from the object; a mirror unit which is disposed on an optical path between the lamp unit and the photosensitive member for guiding the reflection light to the photosensitive member and moves at a predetermined speed ratio with respect to the lamp unit; and a rack-pinion means connected to the lamp unit and the mirror unit to move the units at the predetermined speed ratio. Thereby it becomes possible to simplify the structure of the device and easily adjust the relative position between the lamp unit and the mirror unit at the time of assembling the device. Also, the speed ratio between the lamp unit and the mirror unit can be easily adjusted to be a predetermined ratio.
