Patent ID: 8330786

Claim:
An optical scanner for scanning an object, comprising: at least one light source to emit a light beam to the object, the light source including a laser diode array; an optical element to form the light beam emitted from the laser diode array of the light source into a desired shape; a deflective scanner to deflect the light beam; an optical housing to house the optical element and the deflective scanner, the optical housing including at least one positioning member to position the laser diode array of the light source in an axial direction of the light source by abutting the laser diode array against the positioning member in the axial direction of the light source; a pressing member to press the laser diode array of the light source towards the positioning member to sandwich the laser diode array of the light source between the pressing member and the positioning member and mount the light source on the optical housing, the pressing member having a rectangular plate-like shape; the pressing member further includes: a plurality of pressing surfaces to contact the light source to press the light source; and a mounting surface to be attached to the optical housing, and at least a peripheral portion of the pressing surface elastically deforming when the pressing member is fixed to the optical housing; a mounting member to fasten the pressing member to the optical housing; a through-hole through which a feeding member of the laser diode array is inserted to be provided in a substantially central portion of the pressing member; and a pressing member positioning assembly to position the pressing member in a rotational direction before the pressing member is fixed to the optical housing.
