Abstract:
1. Vibrating device comprising: a dust-screening member disposed in front of an image surface of an image forming element, wherein the image surface is arranged to have an optical image formed thereon, wherein the dust-screening member has a box shape including a bottom surface portion having a light transmitting part through which one of light coming from the image forming element and light coming into the image forming element is transmitted, and side wall portions which are tilted with respect to the bottom surface portion by at most a predetermined angle, wherein the side wall portions extend from all end face portions of the bottom surface portion in a direction of the image forming element, and wherein at least the bottom surface portion has a substantially uniform thickness; and a vibrating member disposed at one of (i) a position of the bottom surface portion other than the light transmitting part of the bottom surface portion and (ii) a flat surface portion of one of the side wall portions, wherein the vibrating member is configured to apply, to the bottom surface portion of the dust-screening member, a vibrational amplitude which is perpendicular to the bottom surface portion; wherein the side wall portions of the dust-screening member are fixed to a fixing member via a soft holding member.
