SCANNING DEVICE OF IMAGE PROJECTION SYSTEM

摘要

PURPOSE: A scanning device of an image projection system is provided to reduce installation scale and realize a clear screen by controlling accurately a light path advancing direction of a synthesized light opposite to vertical and horizontal side of a screen with a first, a second mirror and each rotating member. CONSTITUTION: A vertical side mirror(44) reflects an incident light and is settled to shift a vertical directional position of the path into an appointed angle. A horizontal side mirror(46) reflects an incident light reflected at the vertical side mirror(44) and is settled to shift a horizontal directional position of the path into an appointed angle. A vertical side rotating member(48) is settled at a side or back of the vertical side mirror(44) and rotates the front in vertical direction to get the light path to be shifted into an appointed angle opposite to the vertical direction and to be reflected. A horizontal side rotating member(50) is settled at a side or back of the horizontal side mirror(46) and rotates the front in horizontal direction to get the light path to be shifted into an appointed angle opposite to the horizontal direction and to be reflected.
