1. A vibrating device comprising:
- a vibrator including;
a dust-screening member which is shaped like a plate as a whole and has at least one side that is symmetric with resect to a symmetry axis; and
a vibrating member secured to the dust-screening member and configured to produce, at the dust-screening member, vibration having a vibrational amplitude perpendicular to a surface of the dust-screening member; and
a hold and support member configured to hold and support the vibrator to a fixed member, whereinthe hold and support position by the hold and support member is arranged at position along a circle or ellipse concentric to the centroid of the vibrator such that peak ridges of the vibration having a vibrational amplitude perpendicular to the surface of the dust-screening member form closed loops,a drive unit configured to drive the vibrating member to produce vibration Z(x, y) at the dust-screening member, the vibration being expressed as follows;
Z(x,y)=Wmn(x,y)·
cos(γ
)+Wnm(x,y)·
sin(γ
)where Z(x, y) is vibration at a given point P(x, y) on the dust-screening member;

Abstract
A vibrating device includes a vibrator having a dust-screening member which is shaped like a plate as a whole and has at least one side that is symmetric with respect to a symmetry axis, and a vibrating member secured to the dust-screening member and configured to produce, at the dust-screening member, vibration having a vibrational amplitude perpendicular to a surface of the dust-screening member, and a hold and support member configured to hold and support the vibrator to a fixed member. The hold and support position by the hold and support member is arranged at position along a circle or ellipse concentric to the centroid of the vibrator such that peak ridges of the vibration having a vibrational amplitude perpendicular to the surface of the dust-screening member form closed loops.

9. An image equipment comprising:
-
an image forming element having an image surface on which an optical image is formed; a vibrator including;
a dust-screening member which is shaped like a plate as a whole, has at least one side that is symmetric with respect to a symmetry axis and has a image surface and light-transmitting spaced therefrom by a predetermined distance; and
a vibrating member configured to produce vibration having an amplitude perpendicular to a surface of the dust-screening member, the vibrating member being provided on the dust-screening member, outside the light-transmitting region through which a light beam forming an optical image on the image surface passes;a sealing structure for surrounding the image forming element and the dust-screening member, thereby providing a closed space in which the image forming element and the dust-screening member that face each other; and a hold and support member configured to hold and support the vibrator to the sealing structure, wherein the hold and support position by the hold and support member is arranged at position along a circle or ellipse concentric to the centroid of the vibrator such that peak ridges of the vibration having a vibrational amplitude perpendicular to the surface of the dust-screening member form closed loops, a drive unit configured to drive the vibrating member to produce vibration Z(x, y) at the dust-screening member, the vibration being expressed as follows;
