Abstract:
1. An apparatus, comprising: a light source that turns on or off to produce a light beam corresponding to image data; a collimator lens spaced apart from the light source to collimate the light from the light source; a rectangular mirror, including a first side portion, a second side portion, and a center portion of an outer surface, and a back surface opposite to the outer surface, wherein one of the outer surface and the back surface is a mirror surface; a beam deflector that deflects the collimated light to scan light onto a photoconductor via the rectangular mirror; a frame having a mounting surface on which the back surface of the mirror is mounted and a supporting surface on which a side surface adjacent to the outer surface of the mirror is mounted; a first elastic member having a first pressing portion and a second pressing portion pressing the first side portion of the mirror towards the mounting surface; and a second elastic member having a first pressing portion and a second pressing portion pressing the second side portion of the mirror towards the mounting surface; wherein the mirror is mounted in a mounted position via the frame, the first elastic member and the second elastic member such that the back surface of the mirror is supported by the mounting surface of the frame; wherein the first pressing portion of the first elastic member is configured to press against a first region of the first side portion of the mirror and the second pressing portion of the first elastic member is configured to press against a second region of the first side portion located lower than the first region of the first side portion; wherein the first pressing portion of the second elastic member is configured to press against a first region of the second side portion of the mirror and the second pressing portion of the second elastic member is configured press against a second region of the second side portion located lower than the first region of the second side portion; and wherein each of the first elastic member and the second elastic member has an opening disposed between the first pressing portion and the second pressing portion, so that the first pressing portion and the second pressing portion may elastically press the mirror independently of each other.
