<P>PROBLEM TO BE SOLVED: To provide an air filter cleaning mechanism which prevents dust from outgoing to the outside and adhering to an optical lens or the like even when the way equipment is placed is changed or direction of the equipment is changed. <P>SOLUTION: The air filter cleaning mechanism is provided with a dust collecting container 29 which collects the dust removed from a pre-filter 17 by a dust removing body 21, and a shielding means 30 which is provided in the dust collecting container 29 and remain closed anytime, wherein the shielding means 30 opens interlocked with moving operation of the dust removing body 21. By setting the shielding means 30 to open when the dust removing body 21 having removed the dust from the pre-filter 17 is moved into the dust collecting container 29, the dust removing body 21 moves easily, and the dust adhering to the dust removing body 21 can be collected into the dust collecting container 29. By setting the shielding means 30 to close when the dust removing body 21 is moved to the outside of the dust collecting container 29, the dust in the dust collecting container 29 is not leaked to the outside, thereby preventing a situation that the dust adheres to the optical lens or the like in the equipment in which the air filter cleaning mechanism 2 is mounted and the shadow of the dust is projected to an image. <P>COPYRIGHT: (C)2011,JPO&INPIT |
