ABSTRACT:
The present invention relates to a collimate lens assembly of a laser scanning unit having an improved structure that includes a aperture cap for fixing the collimate lens, a support resiliently supporting the collimate lens and a aperture. The high accuracy collimate lens assembly is achieved according to the present invention without an additional assembling jig, thereby decreasing the assembly time, and the collimate lens can be securely held against any external shocks or vibrations, whereby the productivity is increased.
