| description | A lens shift mechanism includes a movable portion configured to support a projection lens and movable in two directions orthogonal to each other in a plane orthogonal to an optical axis; first and second operating units configured to generate drive forces for moving the movable portion in the two directions, respectively, first and second rotating portions to which the drive forces generated by the first and second operating units are transmitted, and a lock mechanism configured to be capable of switching between a locked state in which the two operating units are locked and an unlocked state in which the two rotating portions are rotatable, and the lock mechanism includes first and second locking members configured to lock the first and second rotating portions respectively and a lever mechanism configured to move the two locking members. |
