Patent ID: 8780158

Claim:
A scan unit for an imaging device, comprising: a mirror movable about an axis; one or more light sources, a light beam generated by each light source being directed toward the movable mirror such that movement of the mirror causes each light beam that is reflected by the mirror to follow a distinct scan pattern; an optical assembly associated with each reflected light beam so as to form an optical path for the reflected light beam from the mirror, the optical assembly including at least one stationary mirror and at least one lens; a housing to which the movable mirror, the one or more light sources and the optical assembly are secured, including a plurality of mounting surfaces, a first group of one or more of the mounting surfaces supporting the at least one stationary mirror of the optical assembly; and at least one adhesive, each of the at least one stationary mirror mounted on and supported by the first group of one or more of the mounting surfaces via the at least one adhesive, wherein for each of the at least one stationary mirror, the at least one adhesive is disposed between the at least one stationary mirror and the first group of one or more of the mounting surfaces so as to prevent any direct contact between the at least one stationary mirror and the first group of one or more of the mounting surfaces, and wherein the at least one adhesive comprises at least two adhesives, the at least two adhesives being different types of adhesives.
