<p><P>PROBLEM TO BE SOLVED: To provide a closing mechanism for a lens shutter having a simple device configuration, for closing the lens shutter sequentially with drawing-out operation of a handle, and opening/closing independently the lens shutter even in the state of storing the handle. <P>SOLUTION: While drawing out the handle 4 for carrying a projector 1 to a carrying position, the engaging end 4b of the handle 4 is engaged with an engagement piece part 6b of a shutter 6 on an open position, and the shutter 6 is moved toward a closed position. A position along a sliding direction of the engaging end 4b and/or the engagement piece part 6b is designed so that an urging force of an alpha-spring 12 acts in a closing direction immediately before the handle 4 is fully drawn out. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
