Abstract
A cost-effective and accurate light source deice for use in an image forming apparatus and including semiconductor lasers is disclosed. The device needs only a minimum number of parts, obviates displacements during assembly, and allows collimator lenses to be adhered by photo-curable adhesive. Even when temperature around the device varies, the distance between the semiconductor lasers in a beam pitch direction varies little.
