<p>PROBLEM TO BE SOLVED: To provide a laser beam deflecting unit having a simple structure capable of performing high speed printing of a stable image by preventing vibration and noise and of facilitating the manufacturing thereof. SOLUTION: This device consists of a laser diode 100 that emits a laser beam, a photosensitive drum 107a that receives the laser beam emitted from the laser diode 100 and a deflecting means 200 that deflects the laser beam emitted from the laser diode 100 toward the photosensitive drum 107a. The deflecting means 200 comprises a reflecting means 201 that reflects the laser beam emitted from the laser diode 100 at a predetermined angle, rotating means 205, 206 that rotates the reflecting means 201 at a predetermined angle range with respect to the photosensitive drum 107a and supporting means 202, 203, 204 each supporting both ends of the reflecting means 201, respectively such that the reflecting means 201 can be rotated.</p> |
