发明名称 PROJECTOR
摘要 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.

主权项 1. A projector comprising: a projection lens configured to project light; and a lens shift mechanism configured to move the projection lens, wherein the lens shift mechanism includes: a movable portion configured to support the projection lens and movable in a plane orthogonal to an optical axis of the projection lens,an operating unit configured to generate a drive force causing the movable portion to be moved by a manual operation,a rotating portion configured to be rotated by the drive force generated by the operating unit transmitted thereto, anda lock mechanism capable of switching between a locked state in which the rotating portion is locked and an unlocked state in which the rotating portion is rotatable, and the lock mechanism includes: a locking member moving along a center axis of rotation of the rotating portion to lock the rotating portion; anda lever mechanism configured to move the locking member to switch between the locked state and the unlocked state.
