STRUCTURE FOR HOLDING OPTICAL COMPONENT, AND OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS INCLUDING THE SAME

摘要

A structure for holding an optical component, includes: first and second flat plate portions provided in a state where the portions stand on a base plate, opposed to each other in a state where the flat plate portions are coupled to each other, and constituting first and second hierarchies, respectively; first and second positioning portions that are provided at the first flat plate portion, and that determine positions of directions of first and second coordinate axes of first, second, and third coordinate axes that intersect with each other; a third positioning portion that is provided at the second flat plate portion, and that determines a position of a direction of the third coordinate axis of the first, second, and third coordinate axes that intersect with each other; and a holding portion coupled to the first flat plate portion or the second flat plate portion, and holding the optical component.
