PROBLEM TO BE SOLVED: To obtain simple constitution by which the position of a video is easily finely adjusted. SOLUTION: A flange body 4 provided on a columnar projection lens unit 7 for projecting an incident video is fixed in a state where it is butted on a projection lens attaching body 9, and light from planar liquid crystal panels 1R, 1G and 1B, which can be optically modulated for every pixel based on image information, is emitted to the unit 7 through a color synthesizing prism 2. A 1st driving pin 5 provided on the flange body 4 is moved in a specified direction with respect to the attaching body 9 by the turning operation of a 1st lens shift cam 20. Thus, the pin 5 is guided by a pin guide hole 8 provided on the attaching body 9 and the flange body 4 is moved along in the radial direction. As a result, the optical axis of the unit 7 is displaced in parallel with the attaching body 9. |
