Abstract:
1. A 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 with an open side, the dust-screening member including a bottom surface portion and a side wall portion, wherein the bottom surface portion has a light transmitting part which extends from a center of the bottom surface portion and through which light for forming the optical image is transmitted, wherein the side wall portion is tilted with respect to the bottom surface portion by at most a predetermined angle and extends from the bottom surface portion in a direction of the image forming element, wherein the bottom surface portion and the side wall portion are integrally formed and have substantially the same thickness, and wherein the side wall portion and the bottom surface portion form the box shape with the open side such that the side wall portion and the bottom surface portion surround a space that is open at a side opposite from the bottom surface portion; and a vibrating member disposed at one of (i) a position of the bottom surface portion other than the light transmitting part and (ii) the side wall portion, wherein the vibrating member is configured to generate, in the bottom surface portion of the dust-screening member, vibration having a vibrational amplitude which is perpendicular to the bottom surface portion.
