| 摘要 |
The present invention provides a light beam emitter that has a simple construction and can direct a light beam toward any positions on the 2D coordinate system, and an image-forming device. In a light beam emitter, an light deflection mechanism has a transmissive light deflection disk, equipped with light deflection areas from which the incident light beam exits toward different positions on the 2D coordinate system depending on the incident positions of the beam, and a drive mechanism that rotates the transmissive light deflection disk in order to change the position of the light beam emitted by the light source device to enter the transmissive light deflection disk.
